Q:How many kinds of plastic raw materials are there? How to distinguish them?

Plastic with its superior performance gradually replaced many has been used for decades, hundreds of years of materials and utensils, becoming an indispensable assistant. Plastic and metal in hard wood, light transparent glass ceramic, corrosion resistance, rubber elasticity and toughness in a body. Therefore, in addition to daily necessities, plastic more widely used in aerospace, medical equipment, petroleum chemical industry, machinery manufacturing, defense, construction and other industries.

Q:What is plastic material E-PET?

With the prevalence of the hardware industry, more industry technology is dazzling, and the technology that we know may not be even longer, so here we are talking about what is the real PET plastic.Polybutylene terephthalate mainly consists of polyethylene terephthalate two (PET) and polybutylene terephthalate (two) (PBT).PET is highly symmetrical and has certain crystalline orientation ability, so it has high film forming ability and plasticity. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, PET has excellent wear resistance, friction and dimensional stability, and electrical insulation. PET bottles are widely used because of their high strength, good transparency, non-toxic, impermeable, light quality and high production efficiency. PBT and PET molecular chain structure similar, most of the same nature, but the main chain from two methylene into four, so the molecules are more supple, processing performance is better.

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:Plastic raw materials, why LDPE and LLDPE?

LDPE is low density polyethylene, that is, high pressure material; LLDPE is linear material.

Q:What is the difference between plastic particles and raw materials?

PP recycled plastics profile: polypropylene (PP) - coloring not translucent, waxy, lighter than polyethylene, transparency is better than polyethylene, polyethylene than rigid. Mainly used for pots, barrels, furniture, thin film, woven bag, packing tape, bottle cap, car bumper.PE recycled plastics: Polyethylene (PE) - no coloring milky white translucent, waxy; touch smooth feeling, soft and tough, slightly elongated, generally low density polyethylene is relatively soft, good transparency, high density polyethylene hard. Mainly used for plastic film, bag, water, oilPS is polystyrene plastic. It is easy to dye and transparent. It is used to make lampshade, toothbrush handle, toy and electrical appliance parts. It is resistant to acid and alkali corrosion, but easily soluble in chloroform, two vinyl chloride, banana water and other organic solvents.

Q:What are the plastic bags made of?

Barrels are usually produced in HDPE, and as for plastic bags, these materials can be made, including polypropylene. Relatively soft is made of high pressure material, relatively hard bag is made of low pressure material, hard and quite, is PP do. Linear low density polyethylene has a strong tear resistance and is generally improved by adding a certain percentage to high pressure polyethylene. The requirements are not too high to add some recycled materials and should be appropriate to reduce the cost of filling masterbatch.

Q:What machines and materials are needed for the manufacture of disposable plastic cups?

Crusher is a large size of solid materials crushed to the required size of the machine. The crusher is composed of coarse crushing, fine crushing, pneumatic conveying and so on. It achieves the purpose of crushing in the form of high-speed impact. The use of wind power as a single powder eliminates traditional screening procedures.

Q:What are the main biodegradable plastic bags made of?

Biodegradable plastics(1) natural polymer modification method. Starch, cellulose, chitin, lignin, seaweed and other natural polymers as raw materials, through chemical modification and copolymerization method, these molecules were modified to synthesize biodegradable plastics.(2) chemical synthesis. The simulation of natural polymer structure, starting from simple water molecules, in the polymer chain of plastic with active groups such as amide, peptidyl, ester compounds containing these radicals, similar to natural protein structure, fragments of grease, easily biodegradable.(3) microbial fermentation, many microorganisms can take some organic substances as carbon source, through metabolism, secrete, produce polyester polymer, these molecules are easy to degrade, and can be further recycled.

Q:What are the raw materials for producing plastic bowls and cups?

Now the plastic bowl is basically made of PP, the quality is better. What's more, the PP bowl can be baked in a microwave oven, and other plastics will not.

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
