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 rubber, wood or aluminum plates on the surface of tooling, hoisting gear and wire rope;
[0006] 4. Manual grinding after welding. Welding spatter is not only labor-intensive, but also difficult to remove completely, and may damage the base metal during grinding.
Spraying special anti-spatter agent near the weld is not only costly, but also difficult to remove after welding;
[0007] 5. The quality of the operators is not the same. It is difficult to prevent the operators from directly stepping on or wearing contaminated gloves and shoe covers to contact the stainless steel plate, which will cause surface pollution

Embodiment Construction
[0023] The invention provides a temporary protective coating for the surface of a stainless steel plate. The temporary protective coating is mainly prepared from chalk powder and latex paint in a mass ratio of 1:1-2.
[0024] By analyzing the requirements and solutions for the surface protection of stainless steel, the following protection method was invented: mixing chalk powder, latex paint and water in a certain proportion, and brushing the pre-protected stainless steel surface 1 to 2 times with a brush. Can play a temporary protective role after drying. After the protection task is completed, it can be rinsed with water or pickled.
[0025] A method for protecting the surface of stainless steel based on the protective coating, the specific steps are:
[0026] 1. According to the mass ratio, mix 1 part of chalk powder and 1-2 parts of latex paint, and stir evenly into a paste-like temporary protective paint for use;
[0027] 2. Unpack the stainless steel plate with good surface co...

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 coating for the surface of a stainless steel plate and a protective method thereof, in particular to a protective coating formulation for the surface of austenitic stainless steel stainless steel material and a method for temporarily protecting the stainless steel material based on the protective coating. Background technique [0002] With the increasing demand for the transportation of fine chemicals in my country, the demand for transportation tanks made of austenitic stainless steel with anti-corrosion and cleaning requirements continues to increase. The sheet material of this material is generally pickled before leaving the factory, and the surface is uniformly silvery white. However, during the manufacturing process of the tank body, the process of blanking, roller, welding, assembly and lifting will cause oil on the surface of the sheet. , Iron ions and other pollution, welding spatter near the weld is d...
