Embodiment 1

[0046] This embodiment provides a wear-resistant and anti-rust valve handle, including the valve handle. The surface of the metal valve is coated with a wear-resistant and anti-rust layer. The specific operation of coating the wear-resistant and anti-rust layer is as follows:

[0047] (1) Clean the valve handle with pure water at a temperature of 95°C, and then blow it dry at a drying temperature of 80°C, then cool it down to room temperature naturally, and clean the rubber surface of the dried valve handle with an aliphatic hydrocarbon solvent for 5 times , rinse again with pure water at a temperature of 45°C, and finally blow dry with a fan for later use;

[0048] (2) Prepare wear-resistant and anti-rust layer coatings, which include the following components in parts by mass:

[0049] Silicone modified epoxy resin: 13 parts, pigment: 2 parts, filler: 12 parts, plasticizer: 1 part, masterbatch: 6 parts, butene: 10 parts, dimethylacetamide: 5 parts, Methyl acetate: 16 parts, ...

Abstract

The invention discloses a wear-resistant and rust-proof valve handle. The surface of a metal valve is coated with a wear-resistant and rust-proof layer, and specific operation of coating the wear-resistant and rust-proof layer comprises steps as follows: (1) cleaning the valve handle with purified water at a temperature of 95-100 DEG C, performing blow drying at a temperature of 80-90 DEG C, cooling the valve handle naturally to the room temperature, cleaning the rubber surface 5-6 times with an aliphatic hydrocarbon solvent with respect to the dried valve handle surface, washing the surface with purified water at the temperature of 45 DEG C, and finally drying the surface by a fan for standby application; (2) preparing a wear-resistant and rust-proof layer coating which is prepared from the following components in parts by mass as shown in the description; (3) sending the valve handle treated in the step (1) to a heating furnace for preheating to 300-350 DEG C, and then sending the preheated valve handle into a spraying device, evenly spraying fine sand to the valve surface for thickness of 0.01-0.03 mm by using a spraying gun, then performing heating curing rapidly, repeating thespraying process until the film thickness is 0.06-0.08 mm; (4) cooling the valve handle coated with the wear-resistant and rust-proof layer, cooling the valve handle to room temperature, and inspecting and warehousing the valve handle.

Description

technical field [0001] The invention relates to the technical field of valves and their processing, in particular to a wear-resistant and anti-rust valve handle and its vacuum heat treatment modification process. Background technique [0002] Metal valves are an important part of the equipment, and metal valves are easily damaged. The damage of parts will easily lead to the scrapping of the whole equipment, which greatly increases the scrapping rate and poses a great threat to environmental pollution. In order to improve This situation reduces the scrap rate, and the invention proposes a wear-resistant and anti-rust valve handle and its vacuum heat treatment modification process. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a wear-resistant and anti-rust valve handle and its vacuum heat treatment modification process in view of the shortcomings of the above prior art, which not only improves the work efficienc...
