In recent years, China's rapid development of PVC pipe plastic pipe industry has formed a great plan, with an annual output of nearly 2 million tons, ranking second in the world in the United States. However, the plastics industry in China is still in its infancy, and technology and equipment rely only on the introduction of imitation transitions. There is still a long way to go between the level of goods and the use of the world. China's joint efforts to advance the plastic pipe from the plastic pipe industry to the plastic pipe industry also require parties.
In recent years, China's rapid development of the plastic pipe industry has now formed a great plan with an annual output of nearly 2 million tons, ranking second in the world in the United States.

There is still a long way to go between the product level and the use plan and the world.
Analysis of the environmental impact of PVC pipe production line:
The PVC pipe production line also imposes a heavy burden on the environment during the production, processing, recycling, consumption, recycling and disposal. Therefore, the use of natural resources and energy to produce non-toxic, non-polluting and environmentally friendly environmental protection. The product is the development direction of PVC pipe. Environmentally friendly PVC plastic products are not a separate product variety, but an evaluation of the attributes of “health, environmental protection and safety”. In addition to its practicality, it also protects human health and protects the environment. Therefore, it is traditional Compared with plastic products, the basic characteristics of five aspects can be summarized: 1) Raw materials used in production should use as little natural resources as possible, and industrial waste should be used as much as possible; 2) Production technology with low energy consumption and production without pollution 3) in the preparation and production of the product, do not use formaldehyde, halide solvents or aromatic hydrocarbons, do not use pigments and additives containing lead, grid, fu and its compounds; 4) the product does not harm human health, and It should be beneficial to human health and has many functions, such as: antibacterial, anti-fog, heat insulation, resistance to tenderness, sound insulation, anti-static, etc.; 5) The product can be recycled or recycled for recycling, and does not produce waste that pollutes the environment.
To this end, the classification and characterization are based on the results of the inventory analysis, and then the resources (including energy) and various environmental modal types are evaluated according to the per capita resource ownership and per capita environmental impact contribution, and the product is considered to be the earth's 矣 oxygen layer. Destruction, the damage to the environment caused by the addition of human waste, is conducive to improving the ecological environment, whether to reduce carbon dioxide emissions. Whether to reduce the impact of radioactive and harmful substances is conducive to reducing the pollution of sound, light, electricity and magnetism. The types of environmental impacts involved in this paper are: global environmental impacts such as atmospheric pollution and non-renewable resource consumption, regional environmental impacts such as water pollution and renewable resource consumption, and local environmental impacts such as solid waste and dust.
China's joint efforts to advance the plastic pipe from the plastic pipe industry to the plastic pipe industry also require parties. Plastic pipes are characterized by a wide range of uses, and in almost every category of plastic pipe selection, PVC pipes continue to have new and useful new needs for advancing new developments. In the rapid development of plastic pipes, China's plastic pipe industry, the world is constantly improving, and a lot of research and development of plastic pipes. The research and development of some hotspots is crucial to breaking the serious impact and promotion of disciplines into plastic tubes.
