Fluorine-lined check valve shell wall thickness and lining layer thickness

by:Lianke Valve     2022-06-30
The determination of the thickness of the lining layer is not only a scientific problem, but also a more realistic economic problem. The thick fluorine lining layer wastes expensive fluoroplastics, and the thin lining cannot meet the requirements of use. Because fluoroplastic is a polymer material, it has the property of absorbing a small amount of gas in contact with it. With the increase of temperature, the volume of the material expands, the gap between the molecules increases, and the penetration and absorption increase. Only a proper increase in thickness can reduce penetration. Therefore, in the design of the lining layer, an increase in thickness is used to make up for this defect.
