Transfer printing processing technology of the hot

Transfer printing processing and manufacturing process of steel plate

steel plate is used in the transfer printing process and can be printed on the surface of non planar objects. The specific processing steps are as follows

1 steel plate grinding: its purpose is to use physical and chemical methods to remove oil stains on the plate, so as to improve its adsorption performance; Avoid defects such as roughness, brittleness, telescopic degumming and difficulty in etching of the printing plate. Generally, more than 300 mesh grinding paste such as hte-201 is selected for grinding

2 steel plate cleaning: use the-202a to drip oil, wash with clean water, and then dry; Or use hte-202b instant detergent to soak in hot water to remove oil stains? Then wipe it with hte-704 surface treatment agent for standby

3 plate making glue: there are two kinds of sensitized the-301 and non sensitized the-302. Sensitized plate making glue is used for fine, high-density and overprinting; On the contrary, use non sensitizing plate making glue. The gluing operation can adopt coating and printing methods respectively. This step is the key of this process technology, which requires flat plane, consistent thickness and good adhesion

4 curing: the sensitized version is dried on the roaster; The non sensitized version is dried with a hair dryer. The drying temperature is controlled at 50 ~ 70 ℃. When hot gas evaporates from the glue, there is no need to dry it and let it dry. Cooling can be placed in the cooling plate, that is, put a sponge and half of the cold water in the plate, so that the curing time of the plate making adhesive is short and the adhesion is firm

5 manuscript film (film): is the content of the inspection thin? Depth of black? Drug film surface? Layout, etc., and then locate on the steel plate

6 exposure: paste the emulsion surface of the positive negative film with the sensitizing adhesive surface, and place it on the plate printer for exposure. The exposure time of ultraviolet light source is 1 ~ 2min, which is shorter, and the development effect is better? Second exposure curing is beneficial to etching forming

7 development: use the-701 developing solution to water, dip it with a brush and gently wipe it on the unexposed part. After exposing the bottom and displaying the image and text, rinse it with clean water and dry it. The higher the moderator is on the contrary Since March, the production and sales of domestic new energy vehicles have returned to the fast lane. The calculation formula is: ha=100- l/0.025. For undeveloped parts, use a fine pointed knife to gently carve and repair. Correct the parts with trachoma or excessive local development with plate making glue, and then dry and expose

8 etching: this step is the key to the quality of steel plate production. All parts are required to be fully prepared before operation? The-801 etching solution is poured into a small plastic bottle or box according to the dosage in advance. Never put it in a metal container? The non etched area around the steel plate should be glued into a box with tape, which is conducive to the release of etching solution by 2014? The steel plate is slightly heated, and the temperature is placed on the shelf in the plastic plate, which is beneficial. And the price of foreign hydraulic components is too high than the etching acceleration? Dip the etching liquid drops into the steel plate picture and text box with a brush, and let it react naturally, or around the steel plate picture and text? Apply evenly 2 ~ 5 times up and down. After 3 ~ 10min, if the picture and text have obvious concave shape, you can put clean water to wash it? The etching depth is about 30 ~ 50 μ m. If not, warm bake and etch the steel plate. The key is to grasp the relationship between etching solution and depth, temperature and time

9 film removal: remove the non sensitized steel plate with the-707; Heat the sensitized steel plate and put it into the disc containing the film removal solution the-901 for film removal? Clean and dry after film removal, and conduct a comprehensive inspection (it is best to use instruments and tools)

10 packaging: put mild oil on the steel plate surface into plastic bags. All working fluids shall be repacked into their respective packages, and tools and articles shall be cleaned and put into special plastic plates. (by Peng Minggang)
