Please ask about the relevant knowledge of plastic particles and what are the raw materials of plast

1 General plastics This type of plastic mainly refers to a type of plastic with large output, wide use and low use. They account for about 80% of the total plastic production. The main varieties are: polyethylene, polyvinyl chloride, polypropylene, polystyrene, phenolic and amino plastics.

2 Engineering plastics generally refer to plastics that can be used as structural materials in engineering technology. The distinctive characteristics of this type of plastic are high mechanical strength, strong chemical resistance and high temperature resistance, which can replace metal or do other special purposes. The main varieties are:

Polyamide, polycarbonate, polyoxymethylene, polysulfone, ABS, polyphenylene ether, fluoroplastics, etc.

There are many kinds of plastic particles, which can be divided into three categories according to their properties: general plastics, engineering plastics, and special plastics.

The main raw materials are:

General Purpose Plastics: Polypropylene.

Polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane.

Wait. Engineering plastics: nylon, PTFE, polyoxymethylene.

Polycarbon, silicone, etc.

Specialty plastics: thermosetting plastics, functional polymer plastics, such as artificial kidneys. Heart. Blood vessels...aerospace industry, etc.

Plastic pellets. Class.

Introduction to PP recycled plastic: polypropylene (PP) - translucent, waxy, lighter than polyethylene, better transparency than polyethylene, and harder than polyethyleneMainly used in basins, barrels, furniture, films, woven bags, packing belts, bottle caps, car bumpers, etc

PE Recycled Plastic Introduction: Polyethylene (PE) - milky white translucent and waxy when uncolored; It has a slippery feeling when touched by hand, flexible and tough, slightly elongated, generally low-density polyethylene is softer, better transparency, and high-density polyethylene.

HarderMainly used for mulch, tote bags, water pipes, oil drums.

PS is a polystyrene plastic, easy to color, good transparency, mostly used in the manufacture of lampshades, toothbrush handles, toys, electrical parts. It is resistant to acid and alkali corrosion, but is easily soluble in chloroform.

Dichloroethylene, banana water.

and other organic solvents.

PVC is a polyvinyl chloride plastic that is brightly colored, corrosion-resistant, and durable. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process, its products generally do not store food and drugs.

Plastic particles can be roughly divided into the following types:

1. Polyolefin particles are made of polyethylene, polypropylene, paraffin, etc.

According to different needs, the formula is not the same, mainly used as additives for pipes, greenhouse films, etc. to reduce costs.

2. Masterbatch, mainly used for dyeing plastic products.

The solid chemicals in the ** extracted from the ground are used for processing and external processing with performance additives to adapt to the processing process.

The raw materials for plastic pellets are various types of plastic resins. Depending on the desired plastic properties and application, the corresponding plastic resin is selected as the raw material. Common plastic resins include, but are not limited to, the following:

Polyethylene: Polyethylene is a common plastic with good flexibility and impact resistance.

Polypropylene: Polypropylene is a plastic with a high melting point and chemical stability, which is widely used in the manufacture of various plastic products.

Polyvinyl chloride (PVC): Polyvinyl chloride is a widely used plastic with good weather resistance and corrosion resistance.

Polystyrene (PS): Polystyrene is a transparent plastic that is often used in the manufacture of crisper boxes, cups, packaging materials, etc.

Polyester: Polyester is a class of plastic materials widely used in textiles and plastic products, used to make fibers, clothing, bottles, etc.

Polycarbonate (PC): Polycarbonate has transparency and impact resistance, and is often used in the manufacture of safety glasses, mobile phone cases, etc.

These are just a few of the common plastic resins, there are actually many other types of plastic resins that can be used as raw materials for plastic pellets, each with its own unique properties and applications. According to the need, select the appropriate plastic resin as the raw material and prepare the corresponding plastic particles.

Imported industrial film or domestic waste shed film, convenience bags, all kinds of waste plastic baskets, plastic buckets.

If there is any problem, you can add recycled plastic ***7788872.

For plastic particles, different companies in different industries have different names: such as granules, rubber materials, recycled materials, etc.

But in general, it is first and foremost a thermoplastic, and thermoplastic refers to a plastic with the characteristics of heating and softening, cooling and hardening, and repeated use is the largest market value. Most of the plastics we use in our daily lives fall into this category. When heated, it softens to the point of flowing, and cooling becomes hard, a process that is reversible and can be repeated.

Polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyoxymethylene, polycarbonate, polyamide, acrylic plastics, other polyolefs and their copolymers, polyirony, polyphenylene ether, chlorinated polyether, etc. are all thermoplastics. The resin molecular chains in thermoplastics are all linear or branched structures, and there are no chemical bonds between the molecular chains, and the process of softening and flowing when heated and cooling and hardening is a physical change.

Thermoplastics are essentially some chemical raw materials, which are mostly powdered, but for the production of daily necessities, utensils, etc., whether it is transportation, storage, production is very inconvenient, so most of them are made of about 2mm particles before entering the circulation channel, and this is also convenient for packaging, dehumidification, weight splitting, color and other advantages, so it forms the plastic particles we need

In addition, plastic pellets can be divided into raw materials (used in production) and recycled materials (recycled materials).

At present, polystyrene and ABS and other general materials are the most factories, and the competition is very large. Business is also very difficult to do.

Recently, the next best business is definitely nylon.

Now there are many manufacturers, there is competition, it is recommended to invest cautiously.

There really isn't one in this area, in fact, this one is very simple, depending on which kind of plastic you choose to make.

The ones that are commonly used are just that, which is quite simple.

You can ask me any questions.

Use: It is to make recycled material drops, that is, to crush the first plastic classification with a crusher, wash it, dry it, use a plastic wire drawing machine to pull it into plastic wire, cool it, send it to a pelletizer to cut it into plastic particles, package it, and complete it! (Drawing, cooling, and pelletizing are completed in one turn.) ）

In daily life, recycled pellets can be used to make various plastic bags, barrels, basins, toys, furniture, stationery and other living utensils and various plastic products;

In the garment industry, recycled pellets can be used to make clothing, ties, buttons, zippers;

Building materials: recycled pellets can be used to make various building components, construction tools, plastic doors and windows, and plaster buckets;

Agriculture: recycled pellets can be used to make agricultural films, pumping pipes, agricultural machinery, fertilizer packaging bags, cement packaging bags;

Machinery industry: recycled pellets can be used to manufacture machine parts after special formulation: various forms of bearings, gears, cams, different wheels, sealing rings, various blades, various water pump impellers;

In the chemical industry, recycled particles can be used as reactors, pipelines, containers, pumps, valves, etc., and are used in chemical production sites to solve corrosion and wear.

There are many types of plastic pellets. Both general materials and engineering materials are available. Common plastic particles include PP, PE, PS, PET, PBT, PVC, ABS, PC, PC ABS, Pa6, PA66, POM, PA6T, PA9T, LCP, PEEK, PTFE, PF and many others, which are widely used in daily products, packaging products, plastic bags, films, toys, auto parts, medical accessories, office accessories, communication digital products, aerospace equipment accessories and so on.

The fields of application of plastic pellets are all-encompassing and almost ubiquitous. The use of plastic pellets, so to speak, is "anything is possible".

Uses of plastic pellets:

1. In daily life, it can be used to manufacture various plastic bags, barrels, basins, toys, furniture, stationery and other living utensils and various plastic products.

2. Garment industry: it can be used to manufacture clothing, ties, buttons, zippers, etc.

6. Chemical industry: It can be used as reactors, pipelines, containers, pumps, valves, etc., and is used in chemical production sites to solve corrosion and wear.

There's so much plastic pellets can do. Your pellets may not be able to make PVC pipes, it depends on the nature of the plastic pellets.

Plastic particles are a general term for plastic raw materials, which have hundreds of varieties, each with different uses and usages, and the PVC you said is only a general term, which is divided into soft and hard, membranes, and so on.

There are many types of plastic pellets, and of course plastic pellets can be injection molded.

If the plastic pellets are PVC material, they can be used to make PVC pipes for threading wires, but if not, they can't.

It can be used for water pipes, wire drawing, and mold blowing. Make woven bags, packing bags, and so on!

PVC material is fine, you can't use PE PP to produce PVC pipes.

I have friends who also make pellets, and they come to buy them.

Plastic particles can be roughly divided into the following types:

1. Polyolefin particles are made of polyethylene, polypropylene, paraffin, etc., adding heavy calcium, talcum powder, etc., according to different needs, the formula is not the same, mainly used as additives for pipes, greenhouse films, etc. to reduce costs.

2. Masterbatch, mainly used for dyeing plastic products.

There are more plastic pellets! Generally, the common ones in our lives such as PE, PP, PVC, PS, PET, ABS, PA, PC, PMMA, etc.; Oita has two categories: hot-melt plastics and thermosetting plastics, which can be regenerated and thermoset can not be regenerated; Hot melt plastics such as general plastics (PE, PP, etc.), engineering plastics (ABS, PA, etc.), elastomers (TPU, TPR, etc.) and other special plastics mentioned upstairs.

General materials, engineering materials, elastomers.
