How to extend the life of polyethylene storage tanks

点击量: 7 Release time: 2018-05-23 Hits: 7

Polyethylene storage tanks have many applications in the industrial field, and the frequency of occurrence is also very high, but everyone does not know much about how to extend the life of polyethylene storage tanks, so today I will introduce you to this topic.

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.

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 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. If the specific gravity of the liquid or liquid is higher or the temperature is higher than 60 ° C, a steel-lined plastic (outer steel inner plastic) storage tank should be selected. This can prevent the deformation of the tank body and extend the service life.

Steel-lined plastic storage tanks are made of carbon steel tanks and then welded with a layer of diamond-shaped steel mesh (100 * 50 * 4) on the surface of the barrel. Polyethylene (PE) is used as the raw material. Technology) The whole is formed on the surface of the steel body at one time. Because the steel mesh (tortoise mesh) and polyethylene are integrated and the steel mesh is welded to the surface of the steel body, it is difficult for the polyethylene liner to escape from the surface of the steel body, so it is an extremely excellent corrosion-resistant product. The lining surface of the product is flat, smooth and strong. Compared with traditional steel-lined glass and steel-lined rubber, the product has better corrosion resistance, wear resistance and long life.
