Printing Scraper Yellow 75A 80A 90A Screen Printing Squeegee PU Material
Product Introduction
Scraping glue is used in the process of screen printing, also known as glue scraping. Most of them are made of PU material. According to the characteristics of the substrate of screen printing, the precision requirements of printing patterns and the different printing methods, different hardness and different cross-section shapes of scraping glue can be selected
Product Function
In screen printing, the function of the squeegee mainly has the following four aspects:
1.It can transfer the ink to the substrate through the screen.
2. It can scrape off excess ink from the screen.
3.It can keep the screen in contact with the substrate line.
4. It can print substrates with different shapes.

Product storage
1. Open the screen printing scraping glue and put the whole strip flat on the flat surface when storing.
2, avoid screen printing scraping edge pressing together, or by other hard objects extrusion.
3. Store in a cool place and avoid any heat source. A cool climate is less damaged than a hot climate, but too cold and too hot environment are not suitable, because it will change the physical properties of screen printing scraper.
4. Avoid exposure to sunlight and ultraviolet rays, and stay away from any welding engineering.
5. Avoid storing with any solvent, because the solvent volatilization in the air will be absorbed by the screen printing scraping adhesive.
6. Never dip the screen printing scraper in ink or solvent.
7, remedy: when the screen printing scraping glue becomes particularly hard because of too cold, the screen printing scraping glue can be dipped in hot water and taken out after flat use. This method also has some effect on the bending that has been caused by rolling storage.
How to choose a good squeegee
1. Considering hardness: The squeegee is usually made of polyurethane. The hardness of the squeegee is measured with a hardness tester. The hardness, size and blade shape of the squeegee determine the flexibility, flexibility and pressure of the squeegee. The hardness ranges from 55 to 90 degrees (Shore A). The hardness value is measured with a Shore A hardness tester. 55A-65A is a low-hard rubber scraper, 66A-75A is a medium hard, and more than 75A is a high hard.
2. Considering from Effective width: refers to the width of the squeegee when the squeegee is loaded into the aluminum squeegee and extends from the aluminum squeegee. This width is very important and determines the bending of the squeegee under pressure. The curvature is a cubic value of the effective width. For example, twice the effective width gives a curvature greater than 23 = 8.
