Professional rubber roller manufacturers professional analysis instructions are silicone roller

Professional Rubber Roller manufacturer professional analysis shows that the professional roller roller manufacturer of Silicone Roller professional analysis is a silicone roller

Looking for the quality of the silicone roller recommended for you to Dongguan Haichang Hardware Rubber, Dongguan Haichang Hardware Rubber Co., Ltd. was established in 2001, is a professional manufacturer of various Industrial Rubber Roller and printing machinery rubber roller. Over the years, relying on strong technical force, advanced machinery and equipment "target=_blank> mechanical equipment, scientific management mode and pragmatic spirit of refinement, with integrity and quality as the purpose, the market share continues to expand, praised by the majority of users .

1) Introduction to silicone roller

It is made of metal or other materials and is covered with silicone rubber. It has high temperature resistance, ozone resistance, chemical inertness and non-adhesion to plastics. It is mainly used for processing hot-adhesive products such as polyethylene calendering, embossing and printing. And film and fabric coating adhesive, plastic composite, corona treatment and other machinery, also used as a sugar production and packaging machine on the release roll and non-woven fabric manufacturing.
Generally speaking, the silicone roller refers to the rubber roller on the heat transfer machine, which is used for the pattern printing special rubber roller on the thermal transfer of toys, electronics, craft gifts and bronzing products.

2) Heat-resistant silicone roller features
1. Excellent high and low temperature resistance, working temperature range -100 to 350 degrees. Excellent resistance to ozone aging, oxygen aging, photoaging and weathering. There is no change in the performance of the silicone roller in the free state for several years, so it is convenient to use the silicone roller in many industries.
2, excellent electrical insulation properties, the electrical insulation properties of silicone roller changes little when the moisture, frequency changes or temperature rise, the silica formed after combustion is still an insulator, so in some environments requiring insulation, silica gel The roller is also used more frequently. In addition, since the silica gel has a small carbon atom in the molecular structure and does not use carbon black as a filler, scorch is less likely to occur during arc discharge, and thus it is very reliable for use in high pressure applications. Its corona resistance and arc resistance are extremely good, the corona life is 1000 times that of polytetrachloroethylene, and the arc life is 20 times that of fluororubber.
3. The silicone roller has special surface properties and physiological inertness. The surface energy of the silicone roller is lower than that of most organic materials. Therefore, it has low hygroscopicity and is immersed in water for a long time. Its water absorption is only 1%, the physical and mechanical properties are reduced, and the mildew resistance is good. Therefore, silica gel is also used in underwater operations or in a humid environment. In addition, the silicone roller does not stick to many materials and can act as an insulator.
4, silicone rubber tasteless and non-toxic has no adverse effects on the human body, the body reacts slightly, has excellent physiological inertia and physiological aging.
5, high gas permeability, silicone roller and other polymer materials have superior gas permeability, the transmittance in the air at room temperature is 30-40 times that of natural rubber, in addition, the silicone roller also has a gas The selectivity is different for the gas permeability of different gases.

3) Use of silicone roller
1. When starting the heating, check whether the silicone roller rotates normally. When shutting down, please pay attention to whether the residual temperature delay is normal, not directly shut down, and the residual temperature delay is set at 40-50 minutes;
2. When the machine is in operation, if it is suddenly powered off due to power failure or other reasons, immediately put on the glove, remove it and put it away in other places to dissipate heat to avoid heat unevenness and burn the silicone roller;
3. When replacing the rubber roller tightly, the silicone should be locked and fixed when the silica gel is heated to the required temperature, but it should not be too tight;
4, silicone roller should keep the surface clean, try to avoid the transfer film debris and other glue to the surface of the rubber roller, such as the surface has dirt, can be used to add industrial alcohol to clean the surface. If stubborn dirt can be polished with fine sandpaper.
5. Like other printing Rubber Rollers, when used or stored, the silicone roller should not collide with other hard objects and be squeezed; away from corroded articles;
6. The temperature of the silica gel can be normally transferred after 190 degrees. In the case of qualified product transfer, the pressure and temperature of the silicone roller should be minimized.
