Mechanical galvanized carbon steel clamping type pipe fittings and its preparation process

Abstract

The invention provides a mechanical zinc-plating carbon steel clamping pressing type pipe fitting, which comprises a carbon steel clampinging pressing type pipe fitting, wherein a zinc tin composite plating layer is respectively arranged on each of the inner wall and the outer wall of the carbon steel clamping pressing type pipe fitting. Meanwhile, the invention also provides a preparation processof the mechanical zinc-plating carbon steel clamping pressing type pipe fitting. By using the preparation process, the mechanical zinc-plating on the inner wall and the outer wall of the carbon steelclamping pressing type pipe fitting can be realized; the anti-corrosion performance of the carbon steel clamping pressing type pipe fitting is improved.

Description

technical field

[0001] The invention relates to a technology for surface treatment of iron and steel parts, in particular to a mechanically galvanized carbon steel clamping type pipe fitting and a preparation process thereof. Background technique

[0002] Mechanical galvanizing is in a solution without external electric field at room temperature, relying on the mechanical rolling energy of the roller and the rubbing of glass beads, using the surface energy to form a multiphase flow environment with collision and rubbing effects, according to the predetermined Zinc powder and chemicals are added to the thickness of galvanizing, and under the joint action of chemical deposition and mechanical collision, a smooth and bright galvanized layer is formed on the surface of the workpiece. The principle of this process is completely different from traditional electroplating and hot-dip plating, with low cost, low pollution, coating thickness can be controlled between 5-100 microns, no...
