Whether manual screen printing or fine machine screen printing, the methods of cleaning, grinding and storing rubber scrapers will directly affect the printing quality. There are several ways to properly maintain screen printing rubber scrapers.

1) Record

The record includes: the characteristics of the new rubber scraper; the name of the seller and the date of purchase; the type of printing suitable for the rubber scraper; the ideal screen printing parameters (squeegee pressure, speed, and theoretical angle); Number of prints; suitable maintenance measures and grinding methods for rubber scrapers.

2) Cleaning

Improper cleaning methods are more damaging than excessive use of rubber scrapers. Attention must be paid to cleaning rubber scrapers:

* Use diluted solvent;

* Do not immerse the rubber scraper in the solvent, even if the solvent is not corrosive, wear gloves and cloth for cleaning;

* Before cleaning, use samples to check the cleaning effect of the solvent glue scraper and whether it is harmful;

* Do not use solvents such as cyclohexanone, acetone, triesters, ethyl ethoxyesters, butyl propyl esters and carbohydrates;

* The hot squeegee after high-speed scraping should not be cleaned immediately. It should be left to dry for at least two hours before cleaning. Because the temperature increase will make the rubber scraping material more permeable, then cleaning the rubber scraping, the solvent will corrode the rubber scraping material.

3) Storage

Squeegee should be stored under the following conditions:

* After use and cleaning, lay it flat on the fixture with the knife edge facing up;

* The new plastic scraper box should be laid flat for 24 hours before use;

* Place in a ventilated place for rapid volatilization; avoid contamination with dust and dirt;

* Maintain constant temperature and constant humidity, the ideal temperature is 15 ~ 25 ℃, avoid light.
