FS type fiberglass corrosion-resistant chemical pump - Product Overview
FS type
FRP corrosion-resistant chemical pumpThe structural design is advanced and reasonable, with a high degree of standardization, universal parts, strong interchangeability, and easy disassembly and maintenance. The components that come into contact with the medium are made of polyvinyl butyral modified phenolic glass fiber, which is molded into phenolic fiberglass parts at high temperatures. The product has excellent properties such as lightweight, high strength, no deformation, temperature resistance, and corrosion resistance. In terms of corrosion prevention, it can partially replace precious metals such as molybdenum containing stainless steel, titanium, and titanium alloys.
FS type fiberglass corrosion-resistant chemical pump - model significance
FS type fiberglass corrosion-resistant chemical pump - selection criteria
Ordinary engineering materials such as steel, stainless steel, aluminum, and lead are not suitable due to severe corrosion in hydrochloric acid. FS type fiberglassCorrosion resistant chemical pumpMost plastics have excellent corrosion resistance to hydrochloric acid.
A type of plastic that can withstand hydrochloric acid at all concentrations and boiling points, such as phenolic, furan, polytetrafluoroethylene, polytetrafluoroethylene, polyvinylidene fluoride, etc.
Phenolic resin (fiberglass) products have good corrosion resistance to non oxidizing acids (hydrochloric acid, dilute sulfuric acid, phosphoric acid, etc.), salt solutions, and water, but are not resistant to corrosion from alkali and oxidizing acids (nitric acid, chromic acid, etc.).
