The three major processes of rubber roller factory production

Rubber cots and blankets, fountain solution and ink cleaners are all printing auxiliary equipment. Although they are used in small quantities in printing, they have a great impact on the quality and stability of printed matter. The industrial rubber roller is also one of the main components of the inking system of the offset printing press. It needs to be in constant contact with water, ink, paper, etc., so it should absorb the minimum amount of water. Compared with metal rollers, industrial rubber rollers have the characteristics of elasticity, acid and alkali resistance, no rust, good ink absorption and ink transfer, and easy cleaning, so they are widely used. The following briefly introduces the three major processes of industrial rubber roller production.

1. Mix. In order to control the content of each component, the temperature of hot baking, etc., so that the hardness and components can be relatively stable. After mixing, because the colloid still has impurities and is not uniform, it has to be filtered. In addition to ensuring that the colloid is free of impurities, the chrome-plated roller manufacturer also ensures that the rubber roller can be evenly stressed during operation.

2. The rubber rubber roller is heated, pressurized and vulcanized to stabilize the plasticizer, so that once the rubber shrinks during use, the shrinkage can be reduced to the smallest degree. Through curing, it can be made soft and firm without losing its softness, and it can finally transfer ink better.

3. Grinding and polishing. Do not need a constant constant temperature for these two steps. Otherwise, if the temperature is too low, it will be easy to become brittle locally. If the temperature is too high, the surface of the rubber roller will be easily carbonized, and the peeling phenomenon will occur during printing, which will lead to the deterioration of the quality of the rubber roller. It does not have its good characteristics and cannot transfer ink well. cause waste.

The rubber roller factory is a special rubber roller for industry, which plays an important role in industrial production. Especially these two steps after Z are the key to determine the quality of the rubber roller. Although the surface of the rubber roller looks smooth, the surface of the tungsten carbide roller still has many small concave and convex parts. Grinding and polishing is to make the rubber roller more accurate in size and smoother surface, so that its ink transfer performance is better, and the quality of the printed product is higher.
