In the fish pond environment, because of the different breeds, the acid and alkali environment in the water is different. We will also take this into consideration when selecting the gas pipe. Today we will analyze the difference in the range of use of different materials.
PE is a polyethylene plastic, the most basic kind of plastic, plastic bags, plastic wrap, etc. are all PE, HDPE is a high crystallinity, non-polar thermoplastic resin. The original HDPE has a milky white appearance and a semi-transparent shape in a thin section. PE has excellent resistance to most of the characteristics of living and industrial chemicals. Because of its wear resistance, acid and corrosion resistance, high temperature resistance, high pressure resistance, etc., especially because this pipe is light and easy to install and move, it is the first choice for new materials.
PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for the surface of floors, ceilings and leather, but because soft PVC contains plasticizer (this is also the difference between soft PVC and hard PVC), the physical properties are poor (such as the water pipe needs to withstand a certain water pressure, soft PVC It is not suitable for use), so the scope of use of the gas pipe is limited. Hard PVC does not contain plasticizers, so it is easy to form and has good physical properties, so it has great development and application value. In the production process of PVC materials, it is bound to add several additives, such as stabilizers, plasticizers, etc. If all environmentally friendly additives are used, PVC pipes are also non-toxic, tasteless and environmentally friendly.
