Problems solved by technology

[0003] 1. The site requirements are relatively strict, and it is not convenient for cross-operation of various products, which will cause certain difficulties for production organization;
[0004] 2. The requirements for equipment are high, and the surface of the equipment in contact with the surface of the plate needs to be scrubbed before each operation
And it is difficult to ensure that all kinds of equipment do not leak oil, and it is difficult to avoid the plate from being polluted by oil;
[0005] 3. It is difficult to ensure that the stainless steel surface will not be polluted simply by using soft rubb

Embodiment Construction

[0023] The invention provides a temporary protective paint on the surface of a stainless steel plate. The temporary protective paint is mainly prepared from chalk powder and latex paint with a mass ratio of 1:1-2.

[0024] By analyzing the requirements and solutions for stainless steel surface protection, the following protection methods were invented: mix chalk powder, latex paint and water in a certain proportion, and brush the pre-protected stainless steel surface with a brush for 1 to 2 times. Provides temporary protection after drying. After the protection task is completed, it can be washed with water or pickled.

[0025] A kind of protection method that carries out stainless steel surface based on this protection coating, its concrete steps are:

[0026] 1. Mix 1 part of chalk powder and 1 to 2 parts of latex paint according to the mass ratio, and stir evenly into a paste for temporary protective paint for later use;

[0027] 2. Unpack the stainless steel plate with a...

Abstract

The invention relates to a protective coating for the surface of a stainless steel plate and a protecting method for the stainless steel surface. The protective coating for the surface of the stainless steel plate comprises 1 to 2 parts of chalk powder and 1 to 3 parts of emulsion paint. The invention provides the temporary protective coating for the surface of the stainless steel plate, which has a simple formula, obvious protection effect and low cost, can effectively reduce labour intensity and difficulties in post washing, acid cleaning and passivation, and is easy to remove. The invention also provides the protective coating-based protecting method.

Description

technical field [0001] The invention relates to a temporary protective paint on the surface of a stainless steel plate and a protective method thereof, in particular to a protective paint formula for the surface of austenitic stainless steel and a method for temporarily protecting the stainless steel based on the protective paint. Background technique [0002] With the increase in the demand for medium shipments of fine chemicals in my country, the demand for transport tanks made of austenitic stainless steel with anti-corrosion and cleaning requirements continues to increase. Sheets of this material are generally pickled before leaving the factory, and the surface is uniformly silvery white. However, during the manufacturing process of the tank, the surface of the sheet will be oily after blanking, rolling, welding, assembly, and lifting. , iron ions and other pollution, and the welding spatter near the weld is difficult to remove, which will cause difficulties in pickling ...
