How to recover ABS plastic

At present, most of the recycled plastics in China are thermoplastic, because it is soluble and plastic. Different origins of waste recycled plastic particles lead to different degrees of use and different prices of waste plastics. First of all, the lighter the color (even colorless and transparent), the wider the use scale, such as white, which can be adjusted into a variety of other colors, and also can be used as white products, so the price is high. Secondly, because of the need of products, various ingredients are added to the materials.

　　Now from the domestic market, it is mainly the content of CaCO3 (stone powder) that determines the use value of waste plastics. The higher the content of CaCO3, the lower the price. From the naked eye, the product is not bright, the content of CaCO3 is on the high side in case of no luster (matte light outside), and it will feel heavy from the feel. The part that is burned with fire will turn red, and it will become gray after calming down. In addition, we need to pay attention to the reinforced products (glass fiber). Now only PA, PBT, P and other reinforced products can be used, and the price is not high. There are a variety of alloy materials, now only ABS + PC is sold in China. Then according to the relative density of recycled plastic particles, we can judge whether the mixed data can be reused. Now the most problem is that ABS and PS are mixed, PC and PMMA are mixed, PVC (bottle) and pet are mixed, PE and PP are mixed. After mixing, it is difficult to separate them by common methods because of the small difference in density.
