How to choose a scraper: the right scraper makes work more efficient

1,Choose according to the difference in the hardness of the strip
The scraping strip is divided into five types: 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, and 90 degrees. The higher the degree, the higher the hardness of the strip, the smaller the degree, the softer the hardness of the strip, generally 75 degrees. Soft and hard to meet most silk screen.

2,Knife shape selection analysis:
The scraper is oily flat and water-based. The general-purpose 75-degree sharp scraper is suitable for textile water-based printing. The flat-mouth scraper is suitable for ink screen printing.
Flat-mouth scraping rubber: It has a certain adaptability and can withstand higher pressure.
Sharp squeegee: It has good flexibility, compliance, and reduced pressure. It is especially suitable for the printing of irregular surface and irregular shape substrates.

3,Size classification and analysis:

①Size resolution:
Taking 50*9 flat 75 degrees as an example, 50 represents the width of the colloid, 9 represents the thickness of the colloid, flat mouth refers to the shape of the knife edge, 75 degree refers to the hardness of the rubber, and the length of the scraper of the wooden handle is mostly one meter long. How long does it take to use it?

Analysis of common problems
1. Is there any other difference between the degree of the rubber knife and the soft and hard?
The higher the degree, the harder the corresponding strip. In the same printing environment, the higher the degree of scraping, the less the amount of ink will be. The lower the degree of scraping, the more the amount of ink will be.

2. What is the difference between flat squeegee and sharp squeegee?
The flat mouth has a certain adaptability and can withstand high pressure. The sharp-mouthed scraping rubber has good flexibility, compliance, and reduced pressure, especially suitable for the printing of irregularly shaped substrates.

3. What should I pay attention to when using transparent glue?
The color of the transparent glue can adjust the original color of the excellent pulp, such as: dark blue, green, red, etc., but need to pay attention to the ratio of 5%-10%, too much color paste will affect the adhesion of the glue. .

4. How to wash the screen after printing?
The water-based glue is soluble in water. Therefore, it can be cleaned immediately after printing, and the screen can be cleaned with water. If the glue is dry on the screen, it needs to be washed with washing water.

5. Why is the printed pattern falling?
The printed glue is naturally dry _ it will take 24 hours to test the adhesion; if the test will still fall after 24 hours, it is usually caused by the mismatch between the selected glue and the cloth.
