Silica gel refers to the silica gel whose main chain is composed of silicon and oxygen atoms alternately, and there are usually two organic groups attached to the silicon atom. Ordinary silica gel is mainly composed of siloxane chains containing methyl groups and a small amount of Z alkenyl groups.

Silicone gasket is a sealing material that is effectively used in some water gates and oil pipelines. Thanks to this product, we can easily avoid all kinds of leaks.

The function and correct use of silicone gaskets:

Silicone gaskets are widely used in electronic products. The main function of the silicone sheet is to use the gap to transfer heat to achieve insulation, shock absorption and sealing effects. However, due to improper use, some users not only cannot achieve the desired effect, but also damage the silicone pad. So what should be paid attention to when using silicone pads?

First of all, the surface of the silicone gasket should be kept clean to avoid sticking dirt, resulting in poor self-adhesive and sealing thermal conductivity.

Secondly, when selecting a large-area heat-conducting silicone sheet, it should be grasped from the center, because the larger silicone pad is not evenly stressed, which will cause deformation and affect subsequent operations.

Third, when in use, you should hold the sheet with your left hand, and tear off one side of the protective film with your right hand. The protective film on both sides cannot be removed at the same time. It is necessary to reduce the number and area of direct contact with the silicone pad to ensure that the self-adhesive and thermal conductivity of the silicone pad are not damaged.

Fourth, tear off one side of the protective film and face the radiator. Align the silicone pad with the heatsink as you lower it slowly. Take care to avoid air bubbles. When peeling off the other side of the protective film and placing it in the heatsink, be gentle so as not to strain or pull up on the silicone pad.

Fifth, if air bubbles are generated during operation, please use a tool to gently wipe the air bubbles, but do not use too much force to avoid damage to the thermal silicone pad. You can also pull up on one end of the silicone gasket and repeat the steps above to perform the operation again.

Sixth, after fastening or using a strong adhesive silicone gasket, apply a certain amount of pressure to the radiator and store it for a period of time to ensure that the silicone gasket is fixed.
