Learn About The Performance Of Rubber Bending Rollers

There are many performances of rubber bending rolls. The difference in performance materials also greatly affects the choice of some users. It specializes in producing all kinds of rubber rollers. It has more than 20 years of experience in manufacturing, strong technical force, sophisticated processing equipment and complete testing means. The material properties of the rubber roller are divided into various types. The following two are briefly introduced to you.

Medium resistance: This coefficient is very important: some rubber rollers need to be used under immersion conditions. Therefore, before using the formula, you should first understand the medium used in the medium, acid, alkali, high temperature, corrosion resistance and resistance. Wear and tear, the performance of various rubbers is superb in the raw materials and formula of rubber.


High temperature resistance rubber roller: The high temperature resistance depends on the type of rubber material selected and the related bonding method. Commonly used hard glue layer combination. This strengthens the joint strength with the drum. However, due to the softening of the hard rubber with the increase of temperature, the bonding strength between the metal and the rubber is lowered, and generally it can only be used at a temperature not exceeding 599. If other special adhesives are used, the use temperature can be raised to 999 degrees or so. If high temperature resistant silicone rubber is used, apply separate adhesives, so be sure to consider the correlation coefficient when using rubber rollers.

In the offset printing operation, the ink is emulsified due to "large water and large ink", and a hydrophilic foundation is formed on the smooth rubber roller to deink the ink. The solution is to remove the emulsifying ink, wash the deinking roller with gasoline, mix it with pumice powder with 5% sodium hydroxide solution, and treat the metal roller (or hard roller) accordingly. The hard roller can also be sanded with fine water sand in the state of water spray. Be careful not to stay in the same place, otherwise the rubber roller will be damaged. The fundamental method is to control the pH of the water hopper and do a good job of water and ink balance.

The rubber roller used for a long time aging, coupled with the erosion of chemicals, causing rotten rubber to drop the "slag", such a rubber roller is best not to use, otherwise it will seriously affect the quality of the printed product.

In order to ensure that production and printing quality are not affected, there must be spare ink rollers, but do not store too much to avoid aging. The rubber roller is stored in the same environment as the blanket. In addition, the rubber rollers should be straight on the journal and the surfaces should not touch each other.
