Melamine tableware safe? Melamine tableware poisonous?

Also known as melamine tableware melamine tableware, melamine resin powder by the heat and pressure molded together, in some cases, also known as melamine. Since melamine has excellent solvent properties and processing simple performance, it is widely used in tableware and other daily necessities. Melamine tableware with cutlery as a new material, is increasingly encroaching on the traditional ceramic and plastic tableware market. Melamine tableware is made by chemical process, then the melamine tableware safe? The melamine tableware tableware used in the daily diet, the melamine tableware poisonous?
To learn more melamine plates? First let us understand the technical specifications of the next melamine tableware. Melamine tableware with the main technical indicators evaporation residue: ≤ 10mg / l; formaldehyde: ≤ 30mg / l; 65% ethanol bleaching test: negative; potassium permanganate consumption: ≤ 10mg / l; products, heat, impact , bending and other performance and health indicators to meet the GB9690-88, QB1999-94 requirements.
Melamine tableware poisonous? Used in our daily lives melamine tableware non-toxic and tasteless, in line with national food hygiene standards and U.S. FDA health standards; melamine tableware and smooth texture, with a ceramic handle, than enamel, plastic cutlery grade stainless steel and general, in recent years human consumption preferred; melamine tableware, chemical stability, high resistance to taste, difficult to taste the food remnants; but can not be used inside the microwave oven heating.
Melamine tableware safe? Melamine withstand temperatures of minus 30 to 120 degrees Celsius, in this context do not produce toxic substances, water is also the highest temperature of 100 degrees, so just to drink, then certainly no problem. There are now some unscrupulous manufacturers to make a profit and use alternative materials such as urea-formaldehyde resin, melamine powder, in the time of purchase must pay attention to. So the best time to buy a large supermarket.

Plastic extruder control system control system

Plastic extrusion machine control systems control systems including heating systems, cooling systems and process parameter measurement system, mainly by the electrical, instrumentation and actuators (ie, control panel and console) composition. Its main role is: to control and regulate the main auxiliary drive motor, the output meet the technical requirements of speed and power, and enable coordination of main and auxiliary; detect and adjust the temperature of the plastic extrusion machine, pressure, flow rate; to achieve control of the entire unit or automatic control. Extruder drive electrical control can be divided into two parts, control and temperature control, to achieve the extrusion process, including temperature, pressure, screw rpm, cooling screw, barrel cooling, product cooling and diameter control, and traction speed, neat cable on the reel and to ensure an empty plate to full plate from the constant tension take-up control. One set of screw speed control is the core of the device. Screw speed and stability in the regulation of the host drive one of the important process requirements. Screw speed and directly determine the volume of the plastic extrusion speed, normal production always want the highest possible speed and to achieve high yield, the extruder screw speed requirements from the start to the desired operating speed, the available speed range to be large. And stability requirements for high speed, because speed fluctuations will lead to fluctuations in the amount of extrusion, impact extrusion quality, so there is no change in the traction line speed case, the change will cause the cable diameter. Similarly, such as wire-speed traction devices can also cause large fluctuations in the changes in cable diameter, screw speed and traction stage through the operation reflected the appropriate instrumentation, extrusion should be closely observed to ensure high yield.
Plastic Machinery shortcomings of traditional control systems:
(1) in the traditional screw extruder systems, screw driven by a DC motor. In the case of direct drive screw directly driven by a gear box; in the case of indirect drive, screw driven by a belt drive and traction. The traditional DC motor itself, there are some drawbacks: for example, the brush DC motor to be replaced once a month, in the dusty or corrosive environment DC motor requires frequent cleaning, and sometimes even need to shop outside of DC motor through into the clean cool air.
(2) indirect drive screw extruder drawback: the existence of belt slip, belt will cause some energy loss, more wear and mechanical devices increases the possibility of failures. The biggest drawbacks of DC motor noise is too large, brush sparking, rotor pollution, motor temperature is too high, inadequate exhaust and electrical shock. Therefore, using the DC motor-screw extruder higher maintenance costs, the initial cost of DC motor higher.
Fourth, the frequency transformation implementation. SAJ-8000 series inverter for extrusion equipment, high-quality performance characteristics, which is due to vector-controlled inverter itself can provide good performance decision.
A high-performance CPU to provide higher frequency response SAJ-8000 series inverter built-in high-speed CPU, high control precision, fast response frequency performance. Extruder process is mainly required outlet pressure constant control equipment at the beginning of work, the speed control, demand pressure is reached, we should switch to pressure control. Switching process should be no impact, need to control the high frequency accuracy, the pressure signal to collusion.
2 Vector Control provides high torque output at low frequencies of the main extruder drive motor, mainly through reduction parallel shaft helical gear reducer drive after turning the screw, the following changes in the fundamental frequency constant torque when the speed governor. Past use of V / F control frequency, due to start considering the load torque, torque to set the corresponding bit to enhance the level, if the torque boost setting is too high, the low-frequency excitation light load will too easily lead to Motor severe fever, affects the stable operation of the device.
The use of speed sensorless vector inverter SAJ-8000 series, use the learning function can be observed from the motor parameters, not only good at low frequencies the motor output characteristics, inverter to run their own energy-saving feature will automatically change with reduced torque output current, not only can save energy, better to eliminate the likelihood of the above-mentioned risks.
3 torque limit and slip compensation structure is automatically set according to motor, speed control accuracy up to 0.1%.

Apple’s requirement to climate conditions

Apple is like low-temperature drying temperature of temperate fruit trees require winter cold, summer heat. Suitable temperature range is the average temperature 9 ~ 14 ℃, extreme cold winter not less than -12 ℃, the highest monthly average temperature in summer is not higher than 20 ℃, ≥ 10 ℃ accumulated temperature of 5000 ℃ or so years, the growing season (April to October ) average temperature of 12 ~ 18 ℃, 7.2 ℃ in winter to be low temperature below 1200 ~ 1500 hours, in order to smoothly through natural dormancy. Generally believed that the annual average temperature 7.5 ~ 14 ℃ of the region, can be cultivated apples. Apple dormancy period is longer. If winter temperatures are high, can not meet the required low temperatures in winter dormancy, spring germination missing. Apple from the world’s most cultivated regions of view, the coldest month in winter (northern hemisphere in January, Southern Hemisphere in July) the average temperature between -10 ~ 10 ℃, low temperature in order to meet Apple’s requirements. Apple’s major producing areas of China in January the average temperature in this limit. Growing season (April to October) average temperature in the 12 ~ 18 ℃, summer (June to August) average temperature in the 18 ~ 24 ℃, the most suitable for the growth of apples. Summer temperature is too high, the average temperature at 26 ℃ or more, bud bad apples. Calorie deficiency, bud not good, if small, acid, color difference, intolerance storage. Autumn temperatures during the day and night, high low, high sugary fruits, color is good, thick peel, fruit powder and more resistant to storage.
Apple in the growing season precipitation precipitation per acre to be about 180 mm. A natural precipitation, the actual use of the fruit trees can absorb about 1 / 3, so the growing season precipitation to 540 mm, is sufficient to use. In the April to September rainfall of 450 mm below the irrigation area is required, the uneven distribution of precipitation in northern China, 70 to 80 percent in July to August and spring is water shortage. In the inland areas with little rainfall, water shortage, and therefore choose to build gardens, must take into account the irrigation and soil moisture measures, but also pay attention to the rainy season drainage measures.
Apple trees sunshine is like light, light enough, before they can grow normally. According to the determination of Shandong Agricultural University, Taian Golden Delicious, the new star, light compensation point of 600 to 800 meters candlelight, the saturation point in 3500 ~ 4500 m candlelight. In this context, increased light intensity, photosynthesis is also strengthened. Sunlight, is caused by a series of reactions, such as leaves leggy, weak, weak anti-pest, a small flower bud, less nutrient storage, low fruit flowering, root growth is also affected, low-sugar fruits, color is also not good.
The growth of Gala Apple soil soil, yield and quality is good or bad influence. The main factor is the soil, soil aeration, soil. In short, Apple needs deep soil, good drainage, rich in organic matter, slightly acidic to slightly alkaline.
Wind winds often bring to Apple’s growth and development of many adverse effects, such as the deflection caused by the crown, affecting flowering, pollination, leaf organ damage and fruit drop, etc., so the establishment of apple orchards in windy areas, you must create a leaked forest.

Plastic extruder is divided into twin-screw extruder and single screw extruder, and more rarely seen and non-screw extruder screw extruder

Melamine plastic tableware, also known as melamine tableware, melamine resin powder by the heat and pressure pressing. Its lightweight, attractive, low-temperature capability, Naizhu, unbreakable and other properties, are widely used in fast food and children’s catering use.
As the melamine powder price high, so some unscrupulous business for the pursuit of profit, direct use of urea-aldehyde molding powder as raw material to produce; some of the aldehydes with urea molding powder as raw material, do the dishes after the the outer surface coated with a layer of melamine powder. Tableware made ​​with urea-formaldehyde, is harmful to humans. Consumers purchase, first go to a regular store, supermarket to buy, do not be cheap, buy at the flea market; Second, purchase equipment to see whether there is significant distortion, chromatic aberration, the surface is smooth, the bottom No injustice, decals are clear, whether wrinkles and bubbles, colored with a white napkin melamine dinner set wipe back and forth whether there is fading and so on.
For: food (fast food) chains, food court, University of (university) canteens, hotels, enterprises and canteens, advertising gifts. As the special nature of the molecular structure of melamine plastic, melamine tableware is not suitable for use in the microwave oven, if using the cracking phenomenon will occur. Melamine plastic tableware cleaning use a soft cloth over, do not use scouring pads, steel ball-like cloth to clean the dishes on the surface, because the scouring pad, steel wool ball will rub the surface of utensils to make it more vulnerable to contamination.

Overview of the extruder

Plastic extruder is divided into twin-screw extruder and single screw extruder, and more rarely seen and non-screw extruder screw extruder
The difference between two kinds of extruder:Single screw and twin screw machines machines: one is a screw, a screw is two. Are used in a motor-driven. Power varies due to the screw double cone of power is about .50 20KW, 65 of about 37KW. screw production and materials related to the production of about 50 conical twin 100-150KG / H, 65 double cone is about 200-280KG / H. yields only a single screw half.
Screw extruder according to their number can be divided into single-screw, twin screw and multi-screw extruder. Currently a single screw extruder is most widely used general materials suitable for extrusion processing. As the twin-screw extruder with less heat generated by friction, materials, subject to uniform shear, a large transmission capacity screw extrusion volume relatively stable, long stay in the machine barrel materials, mix well.
SJSZ series conical twin screw extruder with a force out, high-quality, adaptability, long life, the shear rate is small, the material is not easy to break down, mixing and plasticization performance, direct molding powder characteristics, temperature-controlled , vacuum exhaust and other devices. For tubes, plates, pvc pipe machine and other products production.
Either as a single-screw extruder or molding plastics processing machinery granulating machine has played an important role in recent years, single-screw extruder has been greatly developed. Current German production of large grain with a single screw extruder, screw diameter of 700mm, production of 36t / h.
Single-screw extruder main indicator of development in its key components – the development of the screw. In recent years, there has been a lot of screw theory and experimental research has been nearly a hundred screws, there are separate common type, shear type, barrier type, shunt type and wave type.
Perspective of the development from a single screw, although in recent years has been single-screw extruder better, but with the polymer materials and plastic products continues to develop, but also the emergence of more new features and special single screw screw extruder. Overall, single-screw extruder toward the high-speed, efficient and dedicated direction. Twin-screw extruder feed characteristics, and for powder processing, and more than a single-screw extruder with better mixing, exhaust, response and self-cleaning function, characterized by poor thermal stability of the plastic processing and Total mixing time also show its superiority. In recent years, foreign twin-screw extruder has been a great development, various forms of twin-screw extruder has been serialized and commercialization, production companies is greater.

China’s aluminum industry aluminum material production and consumption

1. China’s aluminum industry aluminum material production and consumption
In recent years, China’s national economy and high stability, sustained and rapid development, to promote China’s aluminum smelting and aluminum processing industry has developed very quickly. China’s aluminum aluminum alloy aluminum extrusion production in 2006 reached 8.793 million tons, more than the U.S. as the first in the world; 2007 output up to 12.508 million tons, an increase of 42.25% in 2006, a new record high; imports in 2007 Industrial aluminum 690,000 tons, an increase of 0.6% in 2006; exported 1.853 million tons of industrial aluminum, an increase of 49.4% in 2006, aluminium profile Net exports of 1.163 million tons; 2007, China’s apparent consumption of industrial aluminum 11,345,000 tonnes.
In January 2008, 1-6 production in China’s aluminum industry, aluminum production 11,129,000 tons, compared with growth of 18.1% over the same period in 2007, expected 2008 annual output of 2,300 tons; electrolytic aluminum production 6.62 million tons, compared with the same period in 2007. growth of 12.9%, production is expected to reach 14.5 million tons the year 2008; aluminum sheet 6.879 million tons, compared with same period in 2007 increased by 38.3%, expected full-year 2008 production will reach 14 million tons.
2. China’s aluminum timber species
In recent years, China’s aluminum industry and scientific development in close connection with the needs of the market, the traditional aluminum material has gradually completed the transition to modern aluminum timber, aluminum timber species so China has undergone tremendous changes. China is an important characteristic of aluminum material to high-performance, high-precision, energy, environmental protection, direction, and many products have become well-known brand, reputation in the domestic market; product quality steadily improved, the product has been in the international advanced standard level ranks, all the major manufacturers in addition to the national standard aluminum production, are able to directly accept the standards of advanced countries by the world’s order. This shows that our aluminum material has the further internationalization of production, but also for the national economy and science and technology to meet the sophisticated needs of a wide range of aluminum, the major aluminum companies also developed a number of internal supply appropriate technical standards.
China’s aluminum alloy material about 300 species, 1,500 varieties of products on the world one of the most abundant species.

Plush toy cleaning methods

[Hand]
Prepare basin filled with water, pour cleaning agents stirring until completely dissolved, it will make stuffed animals into the cleaning agent into the hand squeeze, after raging water and then rinse with water drained, wrapped in a clean, dry cloth stuffed toys a few minutes, will absorb some water, then dried, or allowed to do the sun is also a good way.[Wash] of directly into the washing machine before cleaning, be the first plush toy into the laundry bag, according to general cleaning procedures, use cold wash detergent is more effective than fine, and not to hurt the wool over, if the Use one of the general double-effect shampoo is also good. After washing, dry towel wrap and then required dewatering to avoid harming the surface.
[Wipe] use a soft sponge or a clean dry cloth, dampened with a diluted neutral detergent to wipe off the surface, then rinse clean it again.
[Dry cleaning] can be directly sent to dry cleaners, dry cleaning, or to the hair doll shop, doll hair to buy a special cleaning dry cleaning home cleaning, dry cleaning spray in the hair of their first toy surface, to be twenty-three minutes and then wipe with dry cloth can
[Sunshine law]The sun is the easiest and most effortless way to plush toys clean. UV light can effectively kill some invisible bacteria, plush toys to ensure basic health. But note that this method applies only to relatively shallow plush color because of different fabrics and materials, and some may be stuffed easily fade. Drying, it should be placed outdoors, if the sun radiation through the glass, is not have any bactericidal effect. Plush toys often get dry in the sun outside is very good.
[Disinfection]The longer plush toys, and the internal surface the more bacteria present, wash with water alone can no longer achieve the effect of cleaning. At this point, we must put in the water in the amount of cleaning agents for disinfection. In the washing, we can add the right amount of detergent or liquid detergent for disinfection, to anti-bacterial and anti-mite functions.
After disinfection and washing in the dry process, be sure to intermittent beat of plush toys, so fluffy and soft surfaces and fillers to restore a good shape before washing.

Generating units match

In order to ensure the unit to achieve the technical indicators, unit design and manufacture, diesel engines and generators must be a good match, which includes both power and speed. Diesel power is the rated speed diesel engine to run 12 consecutive hours beyond the normal reach of effective power. The power of synchronous generator is at rated speed, long-term continuous operation, the output terminal to get the rated power. Usually rated engine power (hp) synchronous generator rated power (kW) is called the matching ratio. In the plains the general requirements on the use of the unit matches the ratio of 1.6:1; for some of the demanding mobile power station, take the 2:1 matching ratio. Speed ​​matching requirements are very strict. Speed ​​and unit power, frequency, voltage and others have a close relationship, thus supporting the diesel generator requirements and must have good performance and reliable governor who work to ensure that the generators brought in a relatively short period of time It’s rated speed and stable operation, but also to meet the load changes on the governor’s request.
The unit can run diesel generators to run a single unit can also be incorporated into multiple parallel operation and power system operation. A single unit operation by many conditions: if the power required to meet the heavy conditions, light load operation will reduce the unit to run the economy, and its spare capacity of the unit but also with the same run unit. The use of multiple units operating in parallel and grid operation, can be expanded supply capacity and improve reliability of supply, the standby unit can have a relatively reduced reserve capacity of the unit.
To achieve parallel operation must meet the following four conditions: ① terminal voltage equal; ② same frequency; ③ phase-coherent; ④ the same phase sequence. But also have run protection devices, can automatically adjust the rational allocation and active and reactive power, the unit features and regulator between the FM curve tends to close.
Features diesel engine supplier and turbine-generator group, has the following characteristics: ① output per unit of small size, light weight, simple system, and more generally for the whole package. Therefore, the diesel power plant construction speed. ② high thermal efficiency of diesel power generation, and part-load or light load, the fuel consumption per unit of output changes little. ③ diesel generator starting, stopping with a load and a shorter time, it can start at any time, more suitable for emergency power. ④ than the diesel generator turbine generator operation and maintenance simple and convenient. However, the diesel generator sets are also some disadvantages: ① only use liquid fuel, fuel prices, more expensive, so energy costs are higher. ② engine wear large, short-lived, more frequent maintenance. Operational stability and overload capacity than steam power plant is poor. ③ operation unit vibration and noise, and workers in poor operating conditions. ④ of the magnetic pole surface of the generator must have the brake coil, in order to facilitate the unit starts and stops.
