Abstract

The invention discloses a zinc powder sherardizing method enabling the thickness of a zinc coat to be considerable and uniform. The method comprises the steps of sand blasting, encasing, powder blending, zinc sherardizing, centrifugal zinc shredding, cooling, selecting and packaging. A zinc powder sherardizing agent used during zinc sherardizing comprises the following raw materials of zinc powder, zeolite powder, aluminum chloride powder, aluminum oxide powder, aluminum sulfate powder, cobaltous oxide powder, lead powder, magnesium stearate powder, sodium borate powder, calcium silicate powder, graphene powder, a surfactant, a dispersing agent, a modifier, an activating agent, a diffusant, an intensifier, a chelating agent, an sherardizing accelerant and a stabilizer. The zinc coat of a zinc powder sherardizing product prepared through the method is considerable and uniform in thickness and free of hydrogen embrittlement or surface damage, the zinc sherardizing technology process is free of environment pollution, the zinc utilization rate is high, and the raw materials can be effectively saved.

Description

【Technical field】 [0001] The invention belongs to the technical field of chemical heat treatment of iron and steel surfaces, and in particular relates to a powder zinc sherardizing method with considerable and uniform thickness of a zinc sherardizing layer. 【Background technique】 [0002] Outdoor steel structures and fasteners, highway guardrails, bridges, plumbing appliances, construction hardware, automobiles, construction machinery and other steel parts, powder metallurgy products and steel parts used in chemical, marine, metallurgical, power generation and other projects, often A corrosion resistant protective layer is required. Zinc is the most commonly used chemical element in the surface protection of steel parts: hot-dip galvanized layer, the thickness is generally 15-130μm, the thickness of the component plane and corner coating is obviously different, the uniformity is poor, and it is not easy to control; the thickness of the electro-galvanized layer is generally ...
