What is a Sealing Gasket? What Does It Do?
Sealing gaskets are the elements that play the role of combining between different installation and machine parts in order to prevent leakage in general. The gasket provides the sealing with the compression process. Sealing is possible with the harmonious operation of all components in the system.
Gasket Types Used in Sealing Applications
The sealing gasket is included in the class of static sealing elements and is used to prevent leakage between two stationary elements. According to the working principle of static sealing elements, we can divide them into two classes;
- Elements whose sealing effect depends on the compression ratio (gaskets),
- Elements whose behavior changes in response to pressure, they put more pressure on the surface as the pressure increases (O-ring, U-ring)
Gaskets are available in many types and liquid gaskets used in sealing applications will be mentioned.
Liquid Gaskets in Sealing Applications
Liquid gaskets and form in place gaskets (FIPG) are functionally used to provide sealing between connection surfaces. The advantages of liquid gaskets over other gaskets are that they can withstand high temperatures and can also be used as an adhesive. It is also used to prevent liquid or gas leaks, especially in the application area. It hardens by itself at ambient temperature.
In addition to the liquid seals used in sealing applications, EMI/RF conductive seals are also used in the electronics industry. It is important to protect modern electronic equipment and filters from electromagnetic interference (EMI) and radio frequency interference (RFI) radiated by electrical circuits. Although this can affect the performance of the equipment, it can be easily eliminated by using a gasket made of conductive or absorbent material. Electronic devices must also shield themselves from external interference, which can be brought about by the correct use of an EMI/RFI conductive seal. These liquid seals are very special products (silver, carbon, nickel, etc.) supplemented with electrically conductive materials.
Where are Liquid Gaskets Used in Sealing Applications?
Liquid seals are very popular in many sectors, especially in the petrochemical, defense industry, aviation and automotive sectors. It is especially preferred where equipment such as motor, gearbox, pump, valve and mechanical connections and flanges are used.
