Problems solved by technology

[0002] In the production process of steel plate color coating, it is necessary to coat the coating material containing organic solvent on the steel strip, so that the steel strip with pattern can be produced, which can be used in the fields of houses, electrical appliances, etc. When pre-treating the steel plate, the steel plate The cleanliness and smoothness of the steel plate are poor, resulting in quality defects in the finished product. When the steel plate is baked and solidified, the temperature difference between the two sides of the steel plate is large, which causes the problem of uneven product quality.

Embodiment 1

[0039] The present invention proposes a single-sided color-coated embossing technology for color steel plates, which includes the following steps:

[0040] S1: Pre-degrease, roll and degrease the uncoiled steel plate. After the steel plate is degreased, it is convenient for grinding. After the steel plate is degreased, the steel plate is cleaned. Degreasing steps:

[0041] A. Add warm water into a container with a vibrating mechanism, control the temperature of the water to 60°C, add a degreasing agent, and stir for 3 minutes to obtain a degreasing aqueous solution. The degreasing agent is a mixture of sodium hydroxide, fatty alcohol polyoxyethylene ether and ethylene glycol. , the mass ratio of sodium hydroxide, fatty alcohol polyoxyethylene ether and ethylene glycol is 2:1:3;

[0042] B. Put the steel plate into the container, start the vibration mechanism at the same time, the vibration mechanism speeds up the degreasing speed, control the vibration frequency, control the d...

Abstract

The invention discloses a color steel plate single-sided color-coating embossing technological process. The process includes the following steps that an uncoiled steel plate is pre-degreased, roller-rolled and degreased; after degreasing of the steel plate is finished, the steel plate is subjected to cleaning treatment; a cleaned steel plate is fixed, the outer surface of the steel plate is subjected to grinding treatment, and burrs on the surface of the steel plate are removed; a ground steel plate is water-washed; a water-washed steel plate is wiped; the surface of a wiped steel plate is coated with a passivation solution; a passivated steel plate is color-coated; drying treatment is performed after color-coating is finished; cooling is performed till the temperature reaches the normal temperature after drying is finished; a cooled steel plate is subjected to surface painting treatment; then careful embossing is performed; the painted surface is air-dried and cured through an air-drying mechanism, and the air-drying and curing time is 15-20 minutes; and then a finished-product single-sided color steel plate is obtained after cooling is finished.

Description

technical field [0001] The invention relates to the technical field of color-coated embossing on steel plates, in particular to a color-coated embossing technology on one side of a color steel plate. Background technique [0002] In the production process of steel plate color coating, it is necessary to coat the coating material containing organic solvent on the steel strip, so that the steel strip with pattern can be produced, which can be used in the fields of houses, electrical appliances, etc. When pre-treating the steel plate, the steel plate The cleanliness and smoothness of the steel plate are poor, resulting in quality defects in the finished product. When the steel plate is baked for curing, the temperature difference between the two sides of the steel plate is relatively large, which causes the problem of uneven product quality. Contents of the invention [0003] The present invention proposes a color-coated embossing technique on one side of a color steel plate ...
