When using the triangle scraper, first pour the glue on the front side of the net frame, then slowly scrape and straighten it with the triangle, and then scrape it and dry it. The temperature is maintained at 30-45°C to avoid overheating of the glue and to form heat crosslinks. The film cannot be removed during development.
The dried screen plate is placed on a flat glass plate with the concave surface facing upwards, and the lower surface is covered with black velveteen or red velveteen cloth and clamped with clips. Then put the glass with the bottom plate on the screen plate, clamp the glass with the deep mouth clip, and print it under the printing light box for 3~5min. The distance between the iodine tungsten lamp should be kept away from the layout of 40 ~ 50cm or so, to avoid overheating, development does not penetrate the net. UV cold light should be closer to the distance, printing about 5min. Ultraviolet light is harmful to the human body. It takes a long time for the eyes to see that the object is green, and it should be avoided to observe it with the eyes for a long time. Conditional wear safety glasses. Vacuum printing machine can also be used to print, in short, depending on the conditions.
After the exposure of the screen into warm water in the development of 2 ~ 3min, the water temperature of about 30 °C. After the powder is developed, the two corners of the side are grasped and gently vibrated up and down. The pattern gradually appears. The part that covers the light begins to fall off and forms a stencil. With a high-pressure spray gun sprayed from the opposite side first, the distance is 30cm, and all the patterns are transparent. Then spray from the front, exposing a white breathable mesh, check the pattern against the sun, so far. Do not spray too much. Long spraying will affect the accuracy of the edges of the pattern. Then spin off the water, or use a new towel to dry the water, do not rub it. Only press it up and down, put it in the oven, and dry it in the summer. After drying, the screen is filled with sand, holes, etc. with the original photosensitive adhesive, and then baked for 10 minutes to fully crosslink it. It can also be re-exposed for 10 minutes. Brush on a hardener and let it dry. The purpose is to increase the resistance to printing.
The squeegee can be made by itself, and a piece of rubber strip 0.8 to 1 cm thick is used to cut a piece according to the need, and then a groove of 2 cm thick wood is used to insert the rubber strip into the groove. The edge of the plane shaved into two sides or one side of the slope, leaving 2 ~ 3mm in the middle. Grab the surface into a semi-circle, not to rise hands.
Scrapers can also be purchased ready-made, soft, hard, long, short. The round mouth is suitable for printing rubber and has a large amount of ink. The disadvantage is that it is not suitable for printing fine. The oblique mouth is suitable for printing metallic ink and is printed thin. The tip is suitable for printing paper, and the flat mouth is suitable for fabrics, etc., and can be flexibly used according to the purpose.
The printing materials used for printing pens, flowers, and bird paintings can be modulated with cherry blossom paste, fine white powder, Huabiao white latex and Yidege ink. The formula is as follows:
Cherry brand paste: A bottle of about 500g
Titanium dioxide 10g
Huabiao White Latex 25g
Yidege Ink 20mL
The prepared printing material is stationary for 4 hours, covered with a plastic film and not crusted.
When printing the lines, do not print too dark, the ink is too stiff and rigid, the effect is not good, and it is not easy to complement the line.
The color paste can be used during the printing process, and the white paste is added in proper amount in the black color to make it clear and ink-like.
In order to print the linework, the paper and paperboard are cut according to the design requirements, using boards or glass that are slightly larger than paper or cardboard. Flatten the paper and file, stick it with tape, flatten it by hand, and paste it with another tape.
The printing material preparation during printing is very critical, so as to prevent the infiltration and running of ink during the installation, and it is even more difficult to handle.
For the meat marinating solution we refer to meat tenderizer, Saline mixer, Saline injector(brine injection systems), vacuum massage tumbler.
Saline injector can evenly inject the brine and salt auxiliary materials into the meat blocks, which can shorten the pickling time and greatly enhance the taste and yield of the meat products. The machine can be adjusted with stepping rate, stepping distance, injecting interval and injection pressure according to the technological requirements. Then the brine and salt auxiliary materials can be injected into the meat evenly and continually to reach the optimal effects.
While vacuum tumbler makes meat rolled in the drum under vacuum condition, similar to pulmonary respiration (make product to inflation and shrink alternatively). It makes meat salted evenly, increases the adhesive quality and taste and ensures the freshness of meat.
