Abstract

The invention discloses a strong-acid-resistant high-strength metal valve. The outer surface of the metal valve is coated by a strong-acid-resistant high-strength layer, the strong-acid-resistant high-strength layer is formed by compounding of an A component and a B component, wherein the A component comprises the following materials: 9-13 parts of epoxy resin, 6-13 parts of polyurethane, 8-15 parts of titanium dioxide, 3-7 parts of graphite fluoride, 19-24 parts of barium sulfate, 8-13 parts of a thixotropic auxiliary agent, 14-19 parts of a base-material emulsion, 3-9 parts of an antifreezing agent, 20-25 parts a filler, and 33-39 parts of an auxiliary material; and the B component comprises the following materials: 13-19 parts of nano silicon dioxide, 11-19 parts of butyl acrylate, 1-7parts of a silane coupling agent, 14-19 parts of xylem fiber powder, 20-25 parts of carbon fiber powder, 8-14 parts of a vapor phase corrosion inhibitor, 10-14 parts of antimony trioxide, 19-22 partsof a film forming auxiliary agent, 15-19 parts of a thickener, 4-9 parts of a defoaming agent, and 10-15 parts of a curing agent. The metal valve provided by the invention improves working efficiency,reduces pollution to the environment, and reduces production costs, and the process has simple steps, and is convenient for operation.

Description

technical field [0001] The invention relates to the technical field of valves and their processing, in particular to a strong acid-resistant high-strength metal valve and its surface heat treatment modification process. Background technique [0002] The metal valves in the prior art have low wear resistance and corrosion resistance, and the damage rate is relatively high. The damage of the valve often leads to the damage of the whole product, which greatly increases the scrap rate and poses a great threat to environmental pollution. In order to improve the utilization rate of metal valves, reduce the scrapping rate, and save time and labor, the invention proposes a strong acid-resistant high-strength metal valve and its surface heat treatment modification process. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a strong acid-resistant high-strength metal valve and its surface heat treatment modification process i...
