Now what kind of plastic recycled pellets are more popular in the market

There are five varieties of general-purpose plastics, namely polyethylene, polypropylene, polyvinyl chloride, polystyrene and ABS. They are all thermoplastics.

1.Polyethylene (PE) Polyethylene is the highest yield variety in the plastics industry, widely used in packaging, construction, agriculture, industrial and consumer markets, films, opaque or translucent, light crystalline plastics, with excellent low temperature resistance (the minimum use temperature can reach 70 100), electrical insulation, good chemical stability, can resist the erosion of most acids and alkalis, but not heat resistance. Polyethylene is suitable for processing by injection molding, blow molding, extrusion and other methods.

2.Polypropylene (PP) Polypropylene is a thermoplastic obtained by the polymerization of propylene, usually colorless, translucent solid, odorless and non-toxic, with a density of kg m3 kg m3, which is the lightest general-purpose plastic, and its outstanding advantage is that it has the characteristics of cooking resistance in water, corrosion resistance, strength, rigidity and transparency are better than polyethylene, and the disadvantage is that the low temperature impact resistance is poor and easy to age, but it can be improved by modification and adding additives respectively. There are three production methods of polypropylene: slurry method, liquid phase bulk method and gas phase method.

3.Polyvinyl Chloride (PVC) Polyvinyl chloride is a plastic obtained by polymerization of vinyl chloride, and its hardness can be greatly changed by adding plasticizers. It has a wide range of uses, from hard to soft products.

The production methods of polyvinyl chloride include suspension polymerization, emulsion polymerization and bulk polymerization, and the suspension polymerization method is the main method.

4.Polystyrene (PS) General-purpose polystyrene is a polymer of styrene that has a transparent appearance but has the disadvantage of being brittle, so it can be made into impact-resistant polystyrene (HTPS) by adding polybutadiene. The main production methods of polystyrene are bulk polymerization, suspension polymerization and solution polymerization.

ABS resin is the product of the copolymerization of acrylonitrile, butadiene and styrene, referred to as ABS terpolymer. The properties of this plastic are also very different due to the different proportions of its components A (acrylonitrile), B (butadiene) and S (styrene) in their composition, as well as differences in manufacturing methods. ABS is a combination of injection molding and extrusion processing, so its use is mainly for the production of these two types of products.

The most prevalent are polyethylene (LDPE, HDPE) and polypropylene (PP).

In recent years, the waste plastic recycling industry has become an important part of the sustainable development of the plastics industry. It is not easy to deal with a waste plastic recycling pellet plant.

1. The environmental impact assessment must be carried out in accordance with the national environmental protection laws and regulations, and then approved by the local environmental protection department. Nowadays, the strict environmental protection inspection is completely corrected, and the recycled plastic pellet factories that do not meet the requirements of the environmental impact assessment cannot be opened.

2. There must be clear sewage treatment facilities for the sewage situation, and then discharge it in accordance with the national wastewater discharge standards, and the organic waste gas that may be generated by the absorption of activated carbon can be used for the treatment of waste gas.

3. For solid waste, it is necessary to directly sign a contract with a qualified hazardous waste treatment institution, and they will carry out professional treatment.

Notes:

1. The pellet machine does not matter whether it is good or bad, it is a motor with a gearbox and a screw, and then the material is discharged and formed. It is best not to break the sturdy machine.

2. Screw extrusion granulator Screw extrusion granulator is divided into single screw and twin screw, and there are two types of extrusion forms: front discharge and side discharge. The mixed and kneaded wet materials or materials with low softening point are extruded from the opening template of the machine head under the action of screw conveying and extrusion, and then dried or cooled to obtain a finished granular product, so as to achieve the purpose of changing the powdered product into a uniform granular product.

The plastic compound is too broad, and it is necessary to talk about the classification system.

In general, there are, abs, hips, GP, PP, POM, PMMA, PE, PBT, PVC, etc., ** du has a lot of variables, belonging.

DAO commodities range from a few dollars a kilogram to dozens of dollars. If you want to make plastic**, first you have to distinguish them, and then you can regenerate the granule, how big the plant depends on how much you want to invest, you have to buy a crusher, a pelletizer.

First of all, pay attention.

Environmental issues. Nowadays, the strict inspection of environmental protection is completely corrected, and the regenerated plastic pellet factories that do not meet the requirements of the environmental impact assessment cannot be reborn.

A: Open (of course, there are still a lot of sneaky things).

Secondly, there must be sufficient and advantageous supply.

In addition, it is necessary to understand some necessary technologies, although the requirements are not high, but it is related to quality and cost.

If you can open a plastic pellet factory in your hometown, you will not go out of business and stop production, China will bully outsiders, you will not bully locals, and you will not be able to shut down and stop production.

Since last year, I wanted to open an electronic wire factory, starting from extrusion, but the person who had no choice but to grasp the order was not there.

I am engaged in plastic pellet factory bai for more than 10 years, and I hope for your du opinion.

zhi can help you.

First: It is a DAO to understand the local environmental protection policy, and this is not much.

Are you a ** person? I've been doing this for 20 years, and I can tell you about some of my experiences, 13583844056

Good sales. Plastics have excellent chemical stability, corrosion resistance, electrical insulation, thermal insulation, excellent shock absorption and sound absorption.

Applications of Recycled Plastic Pellets:

Recycled plastic pellets have a wide range of applications. In daily life, recycled pellets can be used to make various plastic bags, buckets, basins, toys, furniture, stationery and other household utensils and various plastic products.

In the garment industry, it can be used to manufacture clothing, ties, buttons, and zippers. In terms of building materials, recycled plastics are sold as derivatives of late vertical particles, and plastic wood profiles are used to manufacture various building components, plastic doors and windows, etc.

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

The raw materials have been used once, but except for high-pressure granulation, most of the imported large parts are used in high-pressure granulation, and if the imported large parts are industrial films, they have not been exposed to the wind and sun, so their quality is also very good.

The processed particles have good transparency, and they should also be judged according to the brightness of the particles and whether the surface is rough. <>

The development of the plastics industry has brought great benefits to mankind, but it has left endless consequences, namely "white pollution". Since the advent of plastic products, it is inevitable that old plastics will be produced, and over time, more new raw materials will be put into use, so that the waste plastics will rise significantly. Because waste plastics are not easy to age and degrade at room temperature, they form increasing white pollution and cause serious damage to the ecological environment.

For this reason, the alarm bell has been sounded all over the world! China's leading and local departments at all levels have successively introduced a series of preferential policies to encourage the treatment and utilization of waste plastics, and give different forms of support such as tax reduction, tax exemption or return of corporate income tax in taxation. It is urgent to find a way to reduce plastic waste pollution, turn waste into treasure, and create huge economic and social benefits.

The application of plastic products in China has penetrated into all corners of society, from industrial and agricultural production to people's clothing, food, housing and transportation, plastic products are everywhere. Arguably, no other material has such a wide range of uses as plastics. At present, the annual output of plastic products in China has exceeded 21 million tons and is developing at a rapid growth rate of more than 13%.

The plastics industry has become an important pillar of China's national economy.

At present, the price of new plastic raw materials in China is 8,000-10,000 yuan, while the recycled particles are only 3,500-6,300 yuan. Significant cost advantages, coupled with the state's long-term implementation of preferential tax policies for enterprises producing and applying recycled particles, plastic products manufacturers actively purchase recycled particles as the main raw material for a medium-sized blown film factory, which consumes more than 1,000 tons of polyethylene recycled particles every year; A medium-sized plastic woven bag factory consumes more than 2,000 tons of polypropylene recycled pellets per year; Even small individual factories require a minimum consumption of several hundred tons per year. Most of the plastic daily necessities on the market are made from recycled pellets.

China's output of plastic products. The amount of consumption ranks first in the world, with an annual per capita consumption of about three kilograms of plastic (eight kilograms per capita in developed countries), and the fourth degree of white pollution in the world. Wherever there are people, there will be plastic waste.

It is of far-reaching significance to process waste plastic products into recycled pellets that are in demand in the market, and to realize a virtuous cycle of resource utilization. Agricultural films, convenience bags, cement bags, food packaging bags, woven bags, beverage bottles, plastic basins, barrels, toys, sandals, vehicle bumpers, household appliance shells, etc., are all raw materials for recycled particles, which are endless and never exhausted. Local purchase is low (758-1800 yuan tons), local processing of recycled particles, low cost, fast effect.

Easily available raw materials can be found everywhere, which provides unique conditions for the establishment of waste plastic recycling pellet factories in various places.
