Corrosion-resistance alloy chemical pump

Abstract

The invention belongs to the technical field of chemical pumps, and particularly relates to a corrosion-resistant alloy chemical pump. The chemical pump comprises a pump body and an antirust coating coated outside the pump body, wherein the antirust coating is prepared from the following raw materials in parts by weight: fluorocarbon emulsion, 2-ethylhexyl epoxystearate, polydimethylsilane, carboxymethyl hydroxyethyl cellulose, converter gas electrostatic precipitator dust having an iron content of 65 percent, butyl methacrylate, methyl-tri-butanone-oxime silane, pentaerythritol oleate, nano-benzotriazole, nano-cobaltous hydroxide, purified terephthalic acid and water. Compared with the prior art, the corrosion-resistance alloy chemical pump has the advantages that the antirust coating used on the surface of an alloy chemical pump can form a compact layer on the metal surface to effectively isolate air and achieve the anticorrosive, antirust and antioxidative effect, cannot be corroded or destroyed by acid and alkali mediums, has small air permeability and water permeability, has an excellent adhesive force on the metal surface to form a certain mechanical strength, and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of chemical pumps, in particular to a corrosion-resistant alloy chemical pump. Background technique [0002] Chemical process pumps In chemical or petrochemical production, pumps work under high temperature, low temperature or ultra-low temperature, high pressure, flammable, explosive, toxic and strong corrosive media. Working under the conditions of high viscosity, small flow and high cavitation puts forward quite strict requirements on the performance of chemical pumps. When manufacturing pumps, a layer of suitable anti-rust paint is usually coated on the pump surface to prevent rust. Function, the ordinary anti-rust paint used to coat the surface of the pump body can play an anti-rust effect, but it will have a certain impact on the subsequent painting, so that the paint cannot be effectively attached to the surface of the pump body, and an additional layer is required Primer to improve its adhesion.

During the use of chemical pumps, with the increase of flow and pressure and the deterioration of negative pressure conditions, it may cause the anti-rust paint to fall off and affect its normal use.
