Hebei Yizhuo New Material Technology Co., LTD., after years of development, leading products are printing cots, industrial cots, office automation cots three series, widely used in printing, office automation, metallurgy, aluminum, wood, leather, paper making, printing and dyeing industries. Our company has 110 sets of production equipment such as mixer, dynamic balancing machine, filter, CNC lathe and lathes, more than 800 pieces of testing equipment, rubber roller products have passed ISO9002 quality system certification and ROHS environmental protection certification.

Industrial rubber rollers should be stored in the temperature of 10-35ºC, the relative humidity of 50-80% of the warehouse. The temperature is too high or too low, will cause thermal cracking or thermal crosslinking of rubber, which will make the rubber surface aging, hardening, loss of due elasticity, cracking, resulting in a drop in energy; In addition, if the humidity is too large, the damp air will cause the roller core moisture absorption rust.

Industrial rubber rollers production process

Mixing is to control the content of each component, the temperature of hot drying and so on, so that the hardness and composition can be relatively stable. After mixing, the colloid is not uniform due to impurities, which has to be filtered. Filtration in addition to colloid without impurities, but also cots in the operation of uniform force. The process of making cots and filtering is particularly important for high-speed presses to prevent expansion or contraction for various reasons.

Then the cots are heated, pressurized and vulcanized to stabilize the plasticizer, so that once the rubber shrinks in the process of use, it can reduce the shrinkage to a small degree. It can be softened by curing, but without losing its softness, transferring ink.

Then there's the grinding and polishing. Do not require constant temperature to perform these two steps. Otherwise, the temperature is too low, local brittle, too high, the surface of the cots is prone to carbonization, peeling phenomenon occurs when printing, resulting in the decline of the cots quality, does not have its good characteristics, can not be very good transfer of ink, resulting in waste. These two steps are the key to determine the quality of cots. Although the surface of the cots looks smooth, there are still many small concave and convex parts on the surface. Grinding and polishing is to make cots size surface smooth, so that the ink transfer performance is good, printing quality is high.

Industrial rubber rollers storage

Generally speaking, cots should be stored in the temperature of 10-35ºC, relative humidity of 50-80% of the warehouse. The temperature is too high or too low, will cause thermal cracking or thermal crosslinking of rubber, which will make the rubber surface aging, hardening, loss of due elasticity, cracking, resulting in a drop in energy; In addition, if the humidity is too large, the damp air will cause the roller core moisture absorption rust.

Because the cots are covered with rubber, in the process of transportation and storage, direct sunlight should be avoided, rain and snow immersion, and acid, alkali, oil and solvent contact should be prohibited, and 2m away from the radiation heat source.

Do not place in strong light and ultraviolet light, ultraviolet light in addition to directly cause the rubber molecular chain fracture and crosslinking, rubber absorption of light energy and free radicals, trigger and accelerate the oxidation chain reaction process. Ultraviolet light acts as heating. Therefore, it is necessary to use thick paper and black plastic cloth to cover the cots around the light protection measures, otherwise it will cause aging, decolorization, cracking, etc., reduce the service life of cots and affect the quality of printing products.

Cots in storage stacking, to support the shaft storage, no extrusion stacking, roller and roller spacing should not be less than 5mm. When handling and moving, it is necessary to lift and hang the shaft part to prevent the rubber surface from squeezing, knocking and scratching.

If the new roller is not used for the time being, please do not open the package, only before the installation can take off the wrapping paper, because the wrapping paper can play a protective role.

In addition, cots should be kept away from high-pressure equipment, motors and other places where ozone may be produced. Because the chemical activity of ozone is much higher than that of oxygen, it is also more destructive and improper storage, which is easy to cause ozone cracking. For cots stored over the standard period, check whether there are defects before use, only in good condition can be used on the machine.
