Example Embodiment

[0032] The present invention adopts the chemical etching etching method to carry out the technical scheme of continuously printing a certain pattern or handwriting on the surface of the strip material:

[0033] Process flow: hot bimetallic cold rolled strip → detergent (40~70℃)→washing (40~70℃)→baking (50~70℃)→printing→neutralizing with lye→water washing (40~70℃) ℃)→baking (50~70℃)→applying anti-rust oil→winding→inspection→warehousing.

[0034] Among them, surface degreasing: it is very important to remove oil stains on the surface during printing production operations. If the oil stains on the surface are not removed, an oil film will form on the surface of the strip to protect the surface of the strip from being corroded or to reduce corrosion, resulting in post-printing The surface of the steel strip has no writing or light writing, and is easily removed by subsequent process friction.

[0035] Solution Preparation: See Table 1.

[0036] When preparing the solution, it sh...

Abstract

The invention discloses a thermal bimetal steel strip surface printing technique, which includes the following steps: a) the steel strip surface is cleaned to remove the oil pollution on the steel strip surface; b) the steel strip surface is corroded by adopting chemical corrosion solution; c) a printing roller is made, and a film with pictures or handwritings is made; photosensitive aniline flexible plates are chosen to carry out photo sensing and baking; a printing plate is made to be coated on a metal roller; the chemical corrosion solution is caused to contact with the steel strip surface selectively; d) the thermal bimetal steel strip with the oil pollution on the surface removed passes through the printing roller stuck by chemical corrosion solution, and certain pictures or handwritings are left on the surface of the thermal bimetal steel strip after the rolling of the printing roller. The thermal bimetal steel strip surface printing technique solves the recognition problem of continuous printing on the surface of the thermal bimetal steel strip in order to distinguish the positive and negative sides of the strip materials by adopting a chemical corrosion and etching method, does not generate the defects interfering in the use on the surface of the cold rolling steel strip, can carry out continuous normal production, causes the printing quality to be easily observed and adjusted, and meets the bulk production requirement.

Description

technical field [0001] The invention relates to a metal surface printing process, in particular to a hot bimetallic strip surface printing process. Background technique [0002] Thermal bimetal is a thermally sensitive composite material that is composed of two or more layers of materials with suitable properties through certain means. Due to the large difference in the expansion coefficients of the two layers of materials (we call the high expansion coefficient the active layer, The low expansion coefficient is the passive layer), when the temperature increases, the material will bend toward the passive layer, when the temperature decreases, the material will bend toward the active layer, and when the temperature returns to the original temperature, the material will also recover to the original state. [0003] Thermal bimetals are usually made into strips or sheets, punched into small components as temperature control components, widely used in aerospace, color TV, home a...
