The sealant 730-C, also called slot Sealant or groove Sealant, is an ideal choice for groove type seals such as the end cover and outlet cover of hydrogen cooled steam turbine generators in thermal power plants. This sealant is made of a single component resin and is free of dust, metal particles, and other impurities. It has excellent sealing performance and a long service life. In order to help everyone better understand and apply 730-C sealant, this article will provide a detailed introduction to its usage method and precautions.

Usage:

1. Fill the sealing groove of the joint surface with sealant 730-C to ensure even distribution of the sealant.

2. Align the outer end cover of the generator with the sealing groove and tighten the bolts evenly.

3. Use an injection tool to inject 730-C sealant into the sealing groove. Glue injection method: Slowly inject from one of the glue injection holes, wait for adjacent holes to flow out sealant, and then inject sequentially until all are filled.

Precautions for use:

Before using sealant 730-C, the joint surface should be cleaned with tools to remove rust and burrs, ensuring that the joint surface is dry and clean.

2. Before installing the end cover, outlet cover, etc., fill the groove with sealant 730, then apply flat sealant, and then install the end cover and other components.

3. Use a glue injection tool to fill each gap with sealant and prevent leakage.

4. If hydrogen gas leakage is found during the operation of the motor, a glue injection tool can be used to expose and fill the groove sealant 730 until the sealing is restored.

Storage precautions:

Sealant 730-C should be placed in a clean, dry, and well ventilated warehouse, and should be well protected from sun, rain, heat, and pressure. Do not approach heat sources or be exposed to sunlight.

2. The best use of sealant is within 1 year after opening. During the validity period of the sealant, it is not necessary to replace the sealant during motor maintenance and disassembly. It needs to be covered well to prevent impurities from mixing in.

3. Sealant should be stored in a dark and dry place, away from sources of fire.

In summary, it is crucial to correctly grasp the usage method and precautions of sealant 730-C to ensure the safe operation of power equipment. With the strong support of the power industry, the research and application of 730-C sealant in China will undoubtedly achieve even more brilliant results, safeguarding the safe operation of power equipment.
