Performance comparison of FRP equipment and PPH equipment

Number

performance

Fiberglass FRP

Plastic PPH

1

Corrosion resistance

temperature resistance

Resin properties, curing method, inner surface felt determined

Single material, in addition to strong oxidizing acid, other media can be used, the operating temperature is 90-110 ℃

2

Anti-aging

The material itself is not easy to degrade, but improper manufacturing will easily delaminate during use, and the fibers will be exposed

Elemental material, the material itself can solve the problem of aging, and the performance remains unchanged during manufacture and use

3

UV resistanceWeather resistance

Very poor, the color of the device will gradually turn yellow and then red under strong light.

Affect the performance of the equipment, which can be solved by adding a UV absorber to the outer layer, but the cost is high

Typically, this performance is enhanced by adding UV absorbers to the raw materials

4

impact resistance

High mechanical strength, but brittle

Good toughness, but brittle at low temperatures

5

Processing technology

The inner layer is made by mold, but manual operation,

The quality is unstable and needs to be checked and processed multiple times

Semi-automatic manufacturing, mature technology, stable quality

6

Environmental friendly

economy

thermoset material

Difficult to handle and expensive to handle

thermoplastic material

Recyclable for other products

7

Widespread use of media

The village material has memory, and there is residual medium intrusion in the pores.

Cannot be cleaned, cannot change storage medium

Residual media can be removed by washing, and storage media can be changed
