Most of the hybrid films and rigid plastics are films made of PE and PP, and the proportion of other films is relatively small. As long as the PP and PE films exceed 50%, they can be made into qualified products. Because, those that can be plasticized can be combined with those that cannot be plasticized and can be used as fillers. Second, the mixing and dispersion problems are considered in the design of the barrel and screw of the equipment, which increases the function of mixing and dispersion; at the same time, the length of the screw barrel is lengthened, so that the plasticization and dispersion are more sufficient.
Because Guowang Machinery's 'mixed waste plastic extrusion molding equipment' is a special equipment for the recycling of mixed waste plastics. Mixed waste plastics can directly make the products you need without the necessary processing of sorting and sorting. Moreover, the quality and performance can meet the requirements of use, and the quality and the plastic recycling equipment price are low, which not only improves the environment and reduces plastic pollution, but also creates considerable economic and social benefits.
The fishing net is made of PE, PP and PA. Before use, PE, PP and PA are cleaned and granulated respectively. Then, PE, PP and PA granules are added to the same direction by a certain proportion through a metering feeder. In the twin-screw one-step extrusion molding equipment, qualified products can be made.
Food packaging film (vacuum packaging film), the amount of food packaging paper is large, and it is difficult to recycle. In order to use it, the paper and plastic must be separated, which has high cost, narrow use, and has an impact on the environment. The utilization problem was solved after the development of the new device. After crushing, a one-step extrusion molding equipment can be used to make pallet products.
The amount of industrial composite membrane is very large. Since it is difficult to utilize composite membranes, it can only be landfilled or incinerated, resulting in land waste and environmental pollution. How to use these composite membranes has attracted great attention from all walks of life. To this end, our plastic recycling machine company has developed a one-step composite film one-step extrusion injection molding equipment to solve this long-standing problem. After the film is broken, it is directly added to the "one-step extrusion molding equipment" to make the products we need, various forms of plastic trays, manhole covers, flower pots and other products.
According to incomplete statistics, more than 1 billion tons of used clothes are dumped into landfills worldwide every year, generating 2 million tons of carbon dioxide emissions every year. What is even more shocking is that by 2030, the impact of old clothes on climate warming will increase to 49%, and climate warming will make more and more polar bears homeless and even extinct. To this end, we change the processing technology, first make waste spinning particles, and then pass the waste plastic particles, waste spinning particles and additives through the metering feeder, which can be added to the co-rotating parallel twin-screw step in different proportions at will. In the extrusion molding equipment, the required products are made.
According to incomplete statistics, China's fast-growing milk carton (Tetra Pak) and beverage market generates about 45 billion discarded composite flexible packaging every year, which is equivalent to 450,000 tons of waste per year if calculated at 10 grams per package. Whether it is landfill or incineration, it will put more pressure on the increase of waste and the environment, and the related waste treatment cost will be nearly 2 billion yuan.
In response to this situation, we have issued "one-step profile equipment for waste milk boxes" and "one-step extrusion molding equipment for milk boxes" to solve the problem of recycling waste milk boxes (Tetra Pak).
