Problems solved by technology

[0002] Anilized special effect color-coated products are rarely produced and applied in China, and basically belong to a blank in the country. There is little experience in the control technology of the production process of anilized products. Through the test production of color coatings, it is found that the anilized shape control of this product is very unstable. During the production process It often happens that the size of the mesh is different, and the daily adjustment and control measures are difficult to ensure its stable and continuous production. The product yield is seriously low at only 96%. Therefore, a new method must be adopted to ensure the stable control of the mesh shape of the mesh special effect product.

Embodiment 1

[0040] 1) Select coating control parameters:

[0041]

[0042] Select the production line speed of the unit to be 70m / min.

[0043] 2) Determine the film thickness control principle, scope and monitoring method:

[0044] During the trial coating and production process, use a wet film meter to measure the wet film thickness on the roller surface by staggering the strip steel on the drive side and the operation side of the topcoat pick-up roller. The duration of each contact measurement is 30s, and the readings on both sides of the wet film meter are summed. Taking the average, the wet film thickness of the working side and the transmission side is required to be measured within 180s; for the thickness of the topcoat, the wet film thickness and paint consumption control are mainly monitored, and the thickness of the primer is based on the direct detection of the dry film thickness;

[0045] Through the coating area, coating rate and control of dry film thickness, it is conve...

[0057] 2) Determine the film thickness control principle, scope and monitoring method:

[0058] During the trial coating and production process, use the wet film meter to measure the wet film thickness on the roller surface by staggering the strip steel on the driving side and the operating side of the topcoat pick-up roller. The duration of each contact measurement is 35s, and the readings on both sides of the wet film meter are summed. On average, the wet film thickness of the working side and the transmission side is required to be measured within 180s; for the topcoat thickness, the wet film thickness and paint consumption control are mainly monitored, and the primer thickness is subject to direct detection of the dry film thickness;

[0071] 2) Determine the film thickness control principle, scope and monitoring method:

[0072] During the trial coating and production process, use the wet film meter to measure the wet film thickness on the roller surface by staggering the strip steel on the driving side and the operating side of the topcoat pick-up roller. The duration of each contact measurement is 40s, and the readings on both sides of the wet film meter are summed. On average, the wet film thickness of the working side and the transmission side is required to be measured within 180s; for the topcoat thickness, the wet film thickness and paint consumption control are mainly monitored, and the primer thickness is subject to direct detection of the dry film thickness;

Abstract

Disclosed is a stability control method for checker forms of a checker color-coated plate. The checker forms of the color-coated plate are subjected to surface pretreatment, the coating process, the film-thickness control process, the curing process and the wind-speed control process are optimized, and a strip steel is staggered on the two sides of a finishing coat lifting roller to measure a wet film through a wet film instrument in the trial coating and production processes; meanwhile, coating consumption in unit time is determined through coating area, coating rate and dry film conversion control and monitored; wet film monitoring and coating consumption control prevail in terms of the finishing coat, direct dry film detection serves as the standard of undercoat, and the color-coated plate with the stable checker forms is obtained. Compared with the prior art, the stability control method for the checker forms of the checker color-coated plate has the beneficial effects that the checker effect is good; the control over the checker forms is stable; the quality loss is reduced; continuous stable production is guaranteed; the product yield reaches over 99%; the checker control quality of a checker special-effect color-coated steel plate is improved; the quality cost is reduced.

Description

technical field [0001] The invention relates to the technical field of color-coated steel sheets, in particular to a method for stabilizing the texture of the textured color-coated steel sheet. Background technique [0002] Anilized special effect color-coated products are rarely produced and applied in China, and basically belong to a blank in the country. There is little experience in the control technology of the production process of anilized products. Through the test production of color coatings, it is found that the anilized shape control of this product is very unstable. During the production process The size of the mesh often varies, and the daily adjustment and control measures are difficult to ensure its stable and continuous production. The product yield is seriously low at only 96%. Therefore, a new method must be adopted to ensure the stable control of the mesh shape of the mesh special effect product.
