Nitrile Silicone Sealing, Waterproof And Oil Resistant Air Filter Seal

1. Specification parameters

It is an elastic rubber sealing ring with axial action, which is used as a non pressure seal of the rotating shaft. The sealing lip has good mobility and adaptability, can compensate for large tolerance and angle deviation, can prevent internal grease or oil leakage, and can also prevent the invasion of external splash or dust. Rubber Seal can produce solid rubber strip, hollow rubber strip, conductive rubber strip, foam rubber strip and special-shaped rubber strip of the following materials. Different cross-section structures can be designed according to the parts and conditions of use. Most customers are generally made of chloroprene rubber, ethylene propylene diene monomer rubber, silicone rubber and other rubber materials with excellent aging resistance due to the requirements of UV aging resistance and ozone resistance. Of course, we also have the ability to produce garlast? Ffkm perfluorinated rubber products. Our manufacturing methods are extrusion continuous vulcanization, extrusion vulcanization tank vulcanization or molding vulcanization. You can also tell us any geometry you need. Contact the sales personnel of RAST sealing products, and we will send technical personnel to assist you to complete the specified sealing system.

4. Production process

It is the mixing rubber through calendering machine pressed into a certain thickness and a width of film method called calendering molding, suitable for the manufacture of simple sheet, plate-shaped products. Some silicone sealing rings, such as tires, rubber cloth, rubber hose and other textile fiber materials must be coated with a thin layer of glue on the fiber is also called paste or rub glue, glue coating process is generally completed on the calender. Extrusion vulcanization can vulcanization or molding vulcanization.

Rubber sealing strips can be classified according to section shape, vulcanization method, application position and purpose, material and other methods.

(1) Discontinuous vulcanization method (cut the extruded rubber strip according to a certain length, put it into the vulcanizing tank for vulcanization, and extrude the semi-finished rubber strip

Put it into the model;

(2) Continuous vulcanization (microwave continuous vulcanization, salt bath continuous vulcanization, hot air continuous vulcanization)

In addition, some methods such as chemical method, etc.

Microwave continuous vulcanization composite sealing strip: microwave vulcanization technology is one of the key technologies of foreign energy crisis in 1970s

After the application and widely promoted production technology. Microwave continuous vulcanization technology can not only produce metal core, solid core rubber and sponge

Moreover, it is superior to other continuous vulcanization devices in energy saving and work efficiency improvement.

5. Operation method

Pay attention to the direction when installing the sealing ring, and do not damage the lip. If the lip has 50 μ The scar on M will cause oil leakage. It is not allowed to install forcibly or use a hammer. You must use a special tool to press the sealing ring into the seat hole, and then use a cylinder to protect the lip. You need to touch some lubricating oil before installation. The size of the replaced sealing ring shall be consistent and must be in strict accordance with the requirements of the manual, otherwise the compactness cannot be guaranteed.
