FRP water tank
common problem
Polyethylene storage tank polymer
The foreign language of polyethylene is referred to as PE. Foreign trade names are Marlex, Hi-Fax, Polythene, Alathon. The highest application temperature is 60 ℃ for low density polyethylene and 70 ℃ for high density polyethylene. The minimum application temperature is -70 ° C. PE storage tank has excellent corrosion resistance. It has good corrosion resistance to non-oxidizing acids (such as hydrochloric acid, dilute sulfuric acid, hydrofluoric acid), dilute nitric acid, alkali and salt solutions, but it is not resistant to concentrated nitric acid and concentrated sulfuric acid. And other strong oxidants.
Polyethylene is a high molecular polymer of ethylene. Due to different production methods, the products are divided into two types: high density (low pressure) and low density (high pressure). The two properties are similar, but the high density polyethylene has a higher temperature resistance under no load and short term (100 ℃, low density is 75 ° C), and the strength is also high. Creep occurs under load and high temperature, and generally does not exceed 65 ° C for long-term use.
They have excellent corrosion resistance, and have good corrosion resistance to non-oxidizing acids (such as hydrochloric acid, dilute sulfuric acid, hydrofluoric acid), dilute nitric acid, alkali and salt solutions, but they are not resistant to concentrated nitric acid, concentrated sulfuric acid and others. Strong oxidant corrosion. Organic solvents generally have good corrosion resistance at room temperature, and high-density products are better, but some solvents can swell them. In the presence of external or internal stress, some volatile liquids or vapors can cause stress corrosion cracking. The product does not need to add stabilizers, enhancers, etc., but when exposed to outdoor elbow, adding carbon black (2%) can improve the resistance to ultraviolet rays.
Polyethylene storage tanks are the most widely used plastics. The processing and forming methods are the same as those of general thermoplastics. They are widely used in films, sheets, and various appliances, and they are used in large quantities in the field of anticorrosion.
