Q:Is plastic bucket and plastic bottle the same raw material?
When the number of the triangle in the bottom of the barrel is "1", the main component of this kind of plastic bucket is polyethylene terephthalate (polyester), which is often called PET. The melting point of this kind of plastic barrel is high, but the heat resistance can only reach 70 degrees centigrade, and it is easy to deform. When the temperature of the plastic barrel is higher than that of the plastic bucket, the possibility of dissolving harmful substances in the plastic barrel is increased, and the material such as wine, oil and the like can be easily twisted and contracted. As China has traditionally been thrifty, people tend to reuse plastic buckets. However, this kind of plastic barrels of repeated use, may release carcinogenic DEHP, if such liquid plastic barrel by people drinking, will may be suffering from cancer, also has toxicity to male testis, its harm should not be overlooked.
Q:What is the raw material for producing high temperature polyethylene plastic bags?
In the process, 2% montmorillonite can be added, which can significantly improve the thermal stability and tensile properties. For specific methods, please refer to the relevant literature.
Q:The difference between resin and plastics
Plastic refers to the resin (or in the process of using monomer polymerization) as the main ingredient, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials, but also can be said to be material with resin as the main raw material and has plasticity and product. Plastic generally refers to finished products, such as plastic cups, plastic bowls and so on.
Q:What do you mean by grade 1, class two or class three in plastic?
Two material is that the raw material has been used once, but high pressure granulation except high-pressure granulation using imported large majority, if import large industrial film has not been exposed to the weather, so the quality is very good, the processed particles with good transparency, then it should be judged according to the brightness and surface whether the rough particles.
Q:How do you increase the transparency and hardness of PP plastic suction pipes? What raw materials do you need to add?
Add transparent nucleating agents to improve transparency, such as milk tea cups
Q:How to use all kinds of plastic materials?
ABS acrylonitrile butadiene styrene copolymerABS acrylonitrile (chemical corrosion resistance, surface hardness of butadiene styrene) (toughness) (good processability, good dyeing weatherability, easy oxidation) with good comprehensive performance, high impact toughness and good mechanical properties, excellent heat resistance, oil resistance and chemical stability, stable size, easy to machine processing, surface plating, good electrical properties.Suitable plastic products: for general structures or wear resistant transmission parts and corrosion protection equipment. Gears, pumps, impellers, bearings, handles, pipes, motors, housings, electronic parts, clocks and watches, water tanks, freezers, refrigerators, housings, stationery, toys
Q:What is plastic film material?
You should first say what type of plastic film you are going to make. You should make a bag or make a plastic wrap. The type is different. You should see what determines what material to use, and the plastic film is also divided into many kinds
Q:Is the plastic with high melting index good?
Its test method is: first let the plastic particles in a certain time (10 minutes), under certain temperature and pressure, melt into plastic fluid, and then through a diameter of 2.1mm tube g (grams) outflow. The greater the value, the better the processability of the plastic material, the worse the contrast.
Q:PVC what is the difference between raw and recycled raw materials?
Raw raw materials, such as rubber oil from rubber trees, are extracted from recycled products and recycled materials are recycled materials.
Q:That kind of plastic bottle blows well
PETA hard, tough, high strength, bright surface with transparent and multi colored sheets. The disadvantage is PET high frequency synthesis is difficult, the price is a bit more expensive than PVC, this material is often high-grade products and environmental requirements of the user to replace the PVC PET material generally used to make packaging for food, beverage, pharmaceutical plastic bottles.
