Waste plastics have a broad prospect of recovering particles, which not only eliminates white pollution, but also saves energy and protects ecological balance, completes the virtuous cycle of resource use, turns waste into treasure, and is strongly supported by the national tax-free policy. Benefiting the country and the people is an occupation that will never be screened. Waste plastic particles are widely used in blowing film, injection molding, wire drawing, tube drawing, extrusion profiles and other processing for new plastic products. Due to its outstanding processing function, easy forming, cutting and welding, plastics can replace some metal or wood products in agriculture, chemical industry and daily life. For example, plastic bags, washbasins, buckets, bottles, shoes, agricultural films, toys and many other plastic products are processed from waste plastic particles.
The market for waste plastic particles is wide. For example, a medium-sized agricultural film factory needs more than one thousand tons of recycled high-pressure polyethylene particles annually. A medium-sized shoe factory needs more than one hundred tons of Recycled PVC particles annually. A smaller private enterprise also needs more than one hundred tons of recycled particles annually. Therefore, there is a big gap in demand for recycled plastics, which can not satisfy the demand of manufacturers. Therefore, the market is excellent and the benefit is excellent. Waste plastics have a wide history, are easy to buy, and are cheap (Nationwide). It's really a short, flat and fast project.
The price difference of particles formed by the same kind of waste plastics may reach about 3000 yuan. There are many reasons. The most important one is the quality of materials. There are many kinds of waste plastics, and their origins and uses are different. Some black heart businesses use recycled plastics and some waste plastics to mix with each other and sell them to customers as good recycled materials. Generally speaking, customers who are not very familiar with recycled materials do not know much about it, so they are often cheated. Now most of the recycled plastics in China are thermoplastic, because it is soluble and plastic. Different origins of waste plastics form different degrees of use of waste plastics and different prices. That's why we call the price diversification of recycled materials. First of all, the lighter the color (or even colorless and transparent), the wider the use scale, such as white, which can be adjusted into a variety of other colors, and can also be used as back white products, with the same price. Secondly, due to the demand of products, various ingredients are added to the raw materials. Now from the perspective of domestic shopping malls, it is mainly the content of CaC03 (stone powder) that determines the use value of waste plastics. The higher the content of CaC03, the lower the price.
From the naked eye, if the product is not bright and lusterless (except for matte), the content of CaC03 will be more, and it will feel heavy from the feel. If you burn it with fire, the burned part will turn red and turn grey after quenching. In addition, we need to pay attention to the reinforced (fiberglass) products. Now only PA, PBT, PP and other reinforced products can be used, and the price is not high. There are also ￠ ￠ kinds of alloy materials. At present, there is only one kind of ABS + PC in the domestic market, but not others. Then, according to the specific gravity (density) of the materials, we can judge whether the mixed materials can be reused. Now the most serious problem is that ABS and PS are mixed, PC and PMMA are mixed, PVC (bottle) and PE are mixed, PE and PP are mixed. After these materials are mixed, it is difficult to separate them in the usual way because of the same density. Therefore, the mixed materials cannot be crushed materials, otherwise the price will be very low, even no one wants. Here also reminds broad buyers that when buying recycled plastics, they should try not to select crushed materials, because it is difficult to distinguish several materials mixed together.
