In the process of manufacturing vibration components, the sealing is an important task. The ating can protect the vibration components from the external environment and improve its stability and life. At present, the commonly used sealing methods are epoxy, silica gel and new modified rubber. The advantages and disadvantages of these three methods are presented separately below.

 
1. Epoxy irrigation sealing method

Epoxy sealing method is the most common method of vibration components. Its advantages are mainly reflected in the following aspects:

1. Excellent heat resistance: epoxy material has good heat resistance, can maintain its performance stable in high temperature environment, will not be caused by temperature changes;
2. Excellent mechanical properties: epoxy materials have high strength and stiffness, which can effectively protect the vibration components from external collisions;
3. Easy to process: epoxy materials have good processing performance, suitable for a variety of complex shapes of vibration components filling;
4.
: Epoxy materials have excellent chemical corrosion resistance and good stability against some common acid and base chemicals.

 However, the epoxy filling method also has some disadvantages:

1. Strong brittleness: epoxy materials are easy to rupture due to long time vibration or external impact;
2. Easy to crystallization: epoxy materials are easy to crystallize under high temperature conditions, which reduces the sealing effect.

 Two, silica gel filling and sealing method

Silicone gel sealing method is a sealing method with the following advantages:

1. Good high and low temperature resistance: the silica gel material has good high and low temperature resistance, and can remain stable in the extreme temperature environment;
2. Excellent flexibility: silica gel material has good flexibility and high elasticity;
3. Highly reliable: the silicone material has good mechanical properties and anti-aging properties.

 At the same time, the silica gel filling and sealing method also has some disadvantages:

1. Poor tear resistance: silica gel material is more prone to tear, which may not be suitable for the vibration components that need to bear a large external force;
2. Low hardness: the hardness of silicone material is low, which is not suitable for some vibration components with hardness requirements.

 Three, the modified rubber filling and sealing method

To meet the more complex and high-strength sealing requirements, ENIENT developed a modified rubber sealing glue EG0552AB. This material combines the elasticity of silica gel, the strength of epoxy, and strong adhesion.merit:

1. Good shock resistance: the material itself has good seismic performance, which can effectively reduce the impact of the vibration components;
2. Excellent sealing: the material has a low permeability, can provide a good sealing effect, protect the vibration components from moisture and dust;
3. Excellent tear resistance: the material itself is more rigid than silicone gel and can withstand tear.
3. High adhesion and substrate versatility: this material has good viscosity for general engineering plastics and metal surfaces, and can provide a bonding strength of 5 Mpa.

 In conclusion, epoxy, silicone and modified rubber can be used for sealing vibrating components. Different methods have their own advantages and disadvantages. The choice of appropriate sealing method needs to comprehensively consider the requirements of vibration components, use environment and production cost.
