The colloid for polyurethane rubber rollers has sufficient surface viscosity to ensure that the rubber rollers have good ink transfer and ink retention properties during the printing process. Its good ink affinity can ensure high-quality printing. When the polyurethane rubber roller is used and selected, if you do not pay attention to maintenance or do not know the selection method, the phenomenon of degumming of the polyurethane rubber roller will occur.
1. The choice of adhesive;
2. Treatment of iron core;
3. The influence of mold and iron core temperature;
4. Mold design and mold requirements;
5. The influence of synthesis process;
6. The influence of pouring process.
Avoid direct sunlight, rain and snow drenching, pressure impact, prohibit contact with acids, alkalis, oils and organic solvents, and be 2 m away from the heat source. And store (-10°c-40°c) in a cool and ventilated room with a relative humidity below 85. Do not approach heat sources or expose to cold air; the rubber layer of the rubber roller must not be compressed. When storing, rotate 180 degrees every half month. The rubber parts should be wrapped in kraft paper or plastic film, and then wrapped in blankets, etc., do not leave them naked, avoid sunlight. The rubber parts should be wrapped in kraft paper or plastic film, and then wrapped in blankets, etc., do not leave them naked , Avoid sunlight, be sure to use spacers to support the roller journal, do not support the rubber part.
During storage, in order to prevent the deformation of the rubber structure, the roller body should be rotated regularly (one half a month is appropriate). Do not use the rubber roller taken from a cold place, especially in the cold winter.
