Rubber gasket selection - 2013-07-08 00:55:29

Rubber gaskets for water, sea water, air, inert gas, bases, salts and water and other media, but the impatience of mineral oils and non-polar solvents, long-term use at temperatures below 70 ℃, the maximum temperature does not exceed 90 ℃, low temperature performance, can be used in a 60 ℃ mouth
Nitrile rubber gaskets for oil products, such as oil, lubricating oil, fuel oil and other long-term use temperature of 120 ℃, such as in hot oil resistant 150'C, temperature is a 10 a 201C.
Neoprene gasket suitable for water, weak acid, weak base, salt solutions, resistance to oxygen and ozone aging performance; NBR oil resistance and excellent secondary to some other general rubber, long-term use at temperatures below 90 ℃, the maximum temperature does not 超过 130 ℃, low temperature for 30 a
50 ℃.
Viton gaskets have multiple varieties, they are with good acid, oxidation resistance and oil resistance, solvent resistance. Acids in the medium, and almost all of the oil and the solvent used, long-term use at temperatures below 200 ℃.
As a flange gasket rubber sheet, used for pipes or frequent removal manholes, hand holes, pressure does not exceed 1. 568MPa,
Due to the various types of gaskets, rubber gaskets softest, fit good performance in a smaller preload can play sealing effect. For this reason, to withstand the internal pressure, partial thickness or due to the low hardness of spacer and easy to be squeezed out.
Rubber material as benzene, ketones, ether and other organic solvents used, prone swelling, weight, soft, sticky phenomena resulting in seal failure. Usually more than 30% degree of swelling can not be used.
In low pressure (0.6 MPa, especially less), under vacuum, with rubber gasket is suitable. Good compactness rubber material, the degree of vacuum of up to 1.3 × 10 - ¹ Pa. Rubber mat in the 10p-¹ '10-³ Pa vacuum range use, subject to bake bake and exhaust treatment.
