PVC pipes sometimes have uneven surface and scratched surfaces. What is the reason?

PVC hose material is polyvinyl chloride, which is one of the largest plastic products in the world. It is cheap and widely used. The polyvinyl chloride resin is white or light yellow powder. PVC is a white powder with an amorphous structure, which has a small degree of branching and is inferior to light and heat. Depending on the application, PVC plastics can exhibit divergent physical and mechanical functions. Can be made into a variety of hard, soft and pvc transparent packaging tube products.

Due to the high chemical invariance of PVC hoses, it can be used to build anti-corrosion pipes, pvc transparent packaging pipes, oil pipes, centrifugal pumps and blowers. PVC hoses are widely used in the chemical industry to construct linings for various types of storage tanks, corrugated boards for buildings, door and window structures, wall decorations and other building materials. It is used in the electrical and electronic industries for the manufacture of plugs, sockets, switches and cables due to its excellent air-breaking edge function. In daily life, PVC is used to make sandals, raincoats, toys and artificial leather!

PVC hoses have high mechanical strength and good corrosion resistance. It can be used to construct waste gas sewage towers and gas liquid transportation pipes in chemical, textile and other industries. PVC hoses can also be used to make storage tanks, centrifugal pumps, fans and armor instead of other corrosion resistant materials. When the plasticizer is inserted in an amount of 30% to 40%, a soft polyvinyl chloride is obtained, which has high elongation, soft finished product, excellent corrosion resistance and electrical insulation, and is often formed into a film for use. Industrial packaging, agricultural nursery and daily raincoats, tablecloths, etc., can also be used to build acid and alkali resistant hoses, cable sheaths, insulation layers, etc.

The wealth of PVC hoses is growing rapidly in the world, and the prospects are spacious and spacious. All countries are optimistic about the potential of PVC and its benefits to the ecological environment. PVC hoses are demonstrating their dip and status to any other person with their superior and weird functions. The products are irreplaceable, social growth requires it, and environmental care needs it. It is an inevitable trend of the progress of our human society.
