PH polystyrene is a colorless, transparent, ductile and malleable thermoplastic. It has good heat resistance and chemical corrosion resistance, and is easy to form and process. PPH tank is one of the commonly used tanks in petrochemical industry.

With the rapid development of China's petrochemical industry, the demand for large oil tanks is growing; At the same time, due to the high corrosiveness of petroleum products, PPH storage tank Its service life is greatly challenged. Therefore, how to improve the anti-corrosion performance and service life of PPH storage tank has become an urgent problem.

I Factors affecting the anti-corrosion performance of PPH storage tank:

1. Influence of raw materials: raw materials are one of the key factors that determine the anti-corrosion performance and service life of PPH.

It mainly includes the following aspects:

(1) Selection of resin and determination of grade;

(2) Selection, proportion and amount of additives;

(3) The selection and quality of filler will directly affect its corrosion resistance and durability;

II Process impact:

Whether the process flow design is reasonable is also an important reason affecting the corrosion resistance and durability of PPH products.

3、 Impact of environmental conditions:

The change of temperature, humidity, atmospheric pressure and other environmental conditions will also affect the physical and mechanical properties of PE materials, which will lead to cracking or peeling of PE products.

IV The construction art level also directly affects the physical and mechanical properties of PE products, and ultimately affects their crack resistance, cracking tendency and service life. PPH mixing tank
