Guoheng Plastics has been widely used in more and more fields with its superior cost performance. It can be said that modified plastics have become a consumer trend, and the following five factors are hidden behind this trend.
1. WEEE (Waste Electrical and Electronic Equipment Directive) 2002/96/EC was promulgated, the maximum working voltage does not exceed 1000Va.c or 1500Vd.c, equipment that works through electric current, electromagnetic field, generator, transformer or equipment that measures such current ; All fit the instruction range. Most of the equipment within the scope of the directive uses plastic materials.
The main purpose of the regulations and directives:
Coordinating the relevant regulations, policies and measures of EU member states on the disposal of waste electrical and electronic equipment to improve the environmental protection capabilities of all relevant personnel involved in the life cycle of electrical and electronic equipment
Prevent or reduce environmental pollution caused by discarded electronic and electrical products
Prevent and control waste electrical and electronic equipment, and realize the reuse, recycling and other forms of recovery of these wastes
Reduce the amount of electronic waste that is finally processed
Improve the utilization of natural resources
Improve the environmental behavior of all operators related to the life cycle of electronic and electrical products
Ensuring environmentally friendly design
Standardize the treatment of waste electronic and electrical equipment by formulating special collection measures, treatment measures and recycling measures for waste electrical and electronic products.
2. After the raw material pretreatment process is mature, the modified environmental protection material meets the requirements of EU RoHS laws and regulations.
Large pieces of casing materials imported from Europe and the United States are pre-processed through multiple processes such as crushing, washing, electrostatic separation, silica gel separation, and color separation to remove impurities, labels, and iron substances in recycled materials, and are harmful to materials and RoHS. Substances are thoroughly separated to ensure that the materials meet the requirements of RoHS laws and regulations.
3. Process improvement and material modification. Provide customers with the best solutions, and the performance meets customer product specifications.
Researchers add functional additives such as tougheners, compatibilizers, lubricants, reinforcing agents, cold inhibitors, fillers, etc. to the separated polymer materials in a certain proportion, and mix them at high speed through a screw before grafting. Change the mechanical properties of materials. According to different customer specifications, make the best formula. It is widely used in various industries of electronic appliances and home appliances.
4. The cost of recycled materials and raw materials is relatively low, with better cost performance.
The cost of recycled materials is relatively low compared to raw materials, supported by laws and regulations around the world and national environmental protection policies. The production cost is relatively advantageous. Since the material itself cannot be directly recycled, it has a wide range of uses after modification and has a good cost-effective value.
5. The prospect is broad and its position in the industry is increasingly prominent.
In recent years, the production capacity of modified plastics in my country has expanded rapidly, and now has a certain scale of development. However, there is still a certain gap in the proportion of modified plastics in general plastics in my country compared with developed countries, and the current consumption of modified plastics in my country is growing rapidly, and the existing production capacity cannot fully meet the needs of the domestic market. There is still a lot of room for development.
Modified plastics add certain ingredients to plastics to change the properties of plastics to meet the needs of producing different products. At present, the world's annual output of modified plastics has reached more than 30 million tons, which are mainly used in automobiles, home appliances, communications, computers and other fields. Judging from the situation in my country, there is a huge demand for modified plastics in computer products, home appliances, communications, auto parts, and high-end tools in the Pearl River Delta foundry industry.
