Features of DECAI Industrial Silicone Rubber Rollers

1. Good high and low temperature resistance, the working temperature range is -100 to 350 degrees. Ozone aging resistance, oxygen aging resistance, light aging resistance and weather aging resistance. The performance of silicone rollers does not change when placed outdoors in a free state for several years, so it is also one of the conveniences for many industries to use silicone rollers.
2. Good electrical insulation performance. The electrical insulation performance of silicone rollers changes little when exposed to moisture, frequency changes or temperature increases. After combustion, the silicon dioxide is still an insulator. Therefore, in some environments that require insulation, silicone rollers The frequency of use is also higher. In addition, there are few carbon atoms in the molecular structure of the silicone roller, and no carbon black is used as a filler, so it is not easy to scorch during arc discharge, so it is very reliable to use in high-voltage applications. Its corona resistance and arc resistance are extremely good, the corona resistance life is 1000 times that of polytetrachloroethylene, and the arc resistance life is 20 times that of fluororubber.
3. The silicone roller has special surface properties and physiological inertia, and the surface energy of the silicone roller is lower than that of most organic materials. Therefore, it has low hygroscopicity, long-term immersion in water, its water absorption is only 1%, the physical and mechanical properties are reduced, and the mildew resistance is good, so silica gel is also used for underwater operations or humid environments. In addition, the silicone roller does not stick to many materials and can play a role in isolation.
4. Silicone rubber is odorless and non-toxic and has no adverse effect on the human body. The body has a slight reaction and has excellent physiological inertia and physiological aging.
5. High air permeability. Compared with other polymer materials, the silicone roller has extremely superior air permeability. The air permeability at room temperature is 30-40 times that of natural rubber. The selectivity of different gases has different permeability.

Mechanical rubber roller
reasons for the degumming of polyurethane coated rollers

When the rubber rollers are stored and stacked, the shaft should be supported for storage. It is strictly forbidden to squeeze and stack them. The distance between the rollers should not be less than 5mm. When carrying and moving, the shaft must be lifted and suspended to prevent the rubber surface from being squeezed, bumped, and scratched.
If the new roller is not in use temporarily, please do not unpack it. The wrapping paper can only be removed before installation, because the wrapping paper can play a protective role.
In addition, the rubber roller should be stored away from high-voltage equipment, motors and other places that may generate ozone. Because the chemical activity of ozone is much higher than that of oxygen, the damage is also greater. Improper storage can also easily lead to ozone cracking. For rubber rollers that have been stored beyond the standard period, check whether there is any defect before use. Only when they are completely intact can they be used on the machine.
