The cylinder materials of sewage pumping station determines the product quality

2020-06-03
Which sewage pumping station is good? Where to buy sewage pumping station? Generally speaking, there are several materials for the cylinder of sewage pumping station, which are HDPE, ABS, PP and GRP. So, what are the differences between the three?

1.HDPE
HDPE is a thermoplastic polyolefin produced by the copolymerization of ethylene. It has a wide range of applications. It is used in applications with high resistance to environmental stress cracking, such as small engine fuel tanks and 90-gal trash cans. In the application of sewage pumping station, it is often more suitable for sewage lifting machine of large box.
2.ABS
ABS material is a polymer with a large output and a wide range of applications. Abs organically unifies various properties of PS, SAN, and BS, and has excellent mechanical properties of toughness, rigidity, and rigid phase balance. ABS is one of the five synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size, good surface gloss, etc. It is easy to paint, can also be used for secondary processing such as metal spraying on the surface, electroplating, welding, hot pressing and bonding. It is widely used in industrial fields such as machinery, automobiles, electronic appliances, instruments, textiles, and construction, wide range of thermoplastic engineering plastics.


 
3.PP
PP has excellent chemical stability and is inert to most acids, alkalis, salts, and oxidants. For example, it is stable in concentrated phosphoric acid, hydrochloric acid, 40% sulfuric acid, and their salt solutions at 100°C. Only a few strong oxidants such as fuming sulfuric acid, etc., may cause changes. PP is a non-polar compound, which is very stable to polar solvents, such as alcohol, phenol, aldehyde, ketone and most carboxylic acids will not make it swell, but it is easy to dissolve or swell in some non-polar organic solvents.
4.GRP
GRP is a composite material, which contains two parts: matrix and reinforcement. The matrix of GRP material is resin, and the reinforcement of GRP material is glass fiber, which plays a reinforcing role. Generally speaking, GRP fiberglass material is one of the widely used materials in sewage pumping stations. It has strong stability, high temperature resistance and corrosion resistance. The sewage pumping station is large in size and the weight of the equipment is known. It is made of GRP anti-corrosion material, which can effectively reduce weight and can be described as light and durable.
