The silica gel sealing strip is a kind of sealing element with a circular section shape. It is widely used in a variety of mechanical equipment, and plays a sealing role in a certain temperature, pressure and different liquid or gas media. Today, Lanxin rubber and plastic small make up to introduce how to extend the use of silicone waterproof sealing ring life:

First of all, in order to make the silica gel sealing strip has excellent sealing effect and extended service life, it is necessary to make the silica gel sealing strip equipment groove and sealing part of the open space design is appropriate, when the open space is too large, the silica gel sealing ring under the action of oil pressure crowded open space, constitute a hazard, and then cause leakage. When the working pressure is less than 9.8mpa, the retaining ring is generally not designed. When the pressure is greater than 9.8mpa, the bearing surface of the silica gel sealing strip is easy to be extruded, and the retaining ring should be added. If one-way compression, a retaining ring is set on the bearing surface, if two-way compression, two retaining rings should be set.

Secondly, after improving the parts of the silica gel sealing strip have relative conflict, to extend the life of the silica gel sealing strip. This way is to choose dry film lubricant coating thermosetting type, its main composition is anti-corrosion type platinum, lead sulfide, antimony elements, such as liquid epoxy compounds, coated with metal surface, low temperature drying curing, form a layer of thick about 0. Olmm more solid film, adhesion strong, not falling, in 1400 ~ 260 ℃ temperature scale normal operation, When the load exceeds 1550okg/mZ, there is still a long wear life.
