Polyolefin refers to polyethylene, polypropylene. They are mainly used to produce films, hollow products and plastic textile bags.
1 Recycling waste polypropylene plastic woven bags The collected waste polypropylene polypropylene woven bags are washed, air-dried, crushed, blended into new polypropylene, and mixed with about 10% low-pressure polyethylene. According to the quality requirements of woven bags, the blending amount can be 20-70%.
Use recycled materials to add a small amount of titanium dioxide and yellow pigments to adjust the color. The incorporation of a small amount of regrind material is slightly different in strength compared with a polypropylene material woven bag of a new material drawing and woven with a uniform weight, but has little effect on the use quality.
2 Manufacture of calcium plastic plastics In waste plastics such as polyethylene, polypropylene and polyvinyl chloride, a large amount of inorganic fillers can be added to make calcium plastic materials. This high-volume waste plastic has similar wood properties, but its rigidity, wear resistance, and heat resistance are superior to wood. Plastic molding methods can be used to process calcium plastic plastic.
Due to the large increase of inorganic fillers in waste plastics, the influence of impurities mixed in waste plastics will not change accordingly. The advantage of this product is its low price, but its strength and color are far less than the products processed by the new materials, and often it can only process black or reddish brown products with little force.
Filled inorganic materials should have fine particle size, good dispersion, low water content, and low price. Commonly used are light calcium carbonate, talcum powder, two fly powder or four fly powder (natural calcium carbonate) and waste generated when the production of sulfuric acid (mainly containing iron oxide) and so on.
