Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a formula for degreasing pine-hole chrome plating and a preparation method thereof, which solves the problem that the existing degreasing method has poor degreasing effect, and the cleaning time is long, and the degreasing agent cannot be realized. To improve the composition of the workpiece to quickly dissolve the processing oil stains on the surface of the workpiece to be treated, it is impossible to achieve the purpose of quickly and fully degreasing by using the degreaser in conjunction with the ultrasonic cleaning method, and it is impossible to achieve both fast and efficient cleaning The workpiece is quickly degreased, so the success rate of chrome plating on loose holes cannot be guaranteed, which brings great inconvenience to people's work on chrome plating on loose holes

Abstract

The invention discloses a formula for degreasing for spongy chromium plating and a preparation method thereof. The formula comprises the following raw materials by weight percent: 40-50 parts of whellote gas, 10-20 parts of hydrocarbon cleaning agents, 1-3 parts of borax, 5-10 parts of corrosion inhibitors, 1-5 parts part of antirust agents, 1-5 parts of surfactants and the balance water. The invention relates to the technical field of electroplating machining. According to the for degreasing for the spongy chromium plating and the preparation method thereof, components of a degreasing agent can be improved to quickly dissolve machining oil stains on the surface of a workpiece to be treated, so that the purpose of quickly and fully degreasing by matching the degreasing agent with an ultrasonic cleaning method is well achieved, and the effect of quickly and efficiently degreasing the workpiece to be cleaned is realized; and the degreasing agent has a good degreasing effect and the cleaning time is short, so that the success rate of spongy chromium plating is well ensured, and the spongy chromium plating of workpieces by people is thus greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a formula for degreasing chrome plating on loose holes and a preparation method thereof. Background technique [0002] Pine hole chrome plating is a special form of wear-resistant chrome plating. The obvious difference between it and general chrome plating is that the surface of the chrome plating layer produces mesh grooves or dot-like gaps. The purpose is to store a certain amount during use. A large amount of lubricating oil is used to improve friction conditions, reduce friction coefficient, and reduce direct metal surface contact, thus improving wear resistance. It can be seen from its principle that this chemical treatment is mainly used for cylinders, cylinder liners, piston rings, and pistons of internal combustion engines. Pins and the repair of parts after wear and tear described above, other parts under the adjustment of lubricating oil can be subjected to such ...
