Generally, it is filled with foam, which is basically sold in hardware and building materials stores, and the small bottle of 10 yuan\/bottle is with a tube. Large bottles of about 20, but to use the foam gun, the general air conditioning hole is not much, a small bottle is enough. It is very easy to use, the specific use method is to shake well before use, and then put in the hole, press the pipe by hand, so that it can be sprayed. Note, it is best to seal one side with a board or tape on both sides, and then block the other side after filling, so that it is fully foaming inside, so that there is relative hardness, and then cut the excess higher than the plane with a knife.
The things that block the holes in air conditioning pipes are usually called pipe plugs or pipe plugs. It is a device used to plug holes or interfaces in air conditioning pipes, usually made of rubber, plastic or metal. The role of the pipe plug is to prevent air or water from leaking out of the pipe and maintain the sealing performance of the pipe. Pipe plugs are one of the essential tools when installing or servicing an air conditioning system. It can effectively prevent impurities and dust in the pipeline from entering the system and ensure the normal operation of the air conditioning system.
The air conditioning hole is called sealing putty, which is used to prevent water and mice. Sealing putty is made of butyl rubber as the base material and mixed with some auxiliary materials. It has good adhesion and waterproof sealing performance with cement, concrete, ceramics, rubber, plastics, wood and various metal materials, especially with excellent air tightness, water tightness and extensibility, and ADAPTS to the appropriate deformation of the base.
This kind of sealing putty has no vulcanization process and has non-drying pi3tt and repairability. Is a single component. Easy to use, mainly polyisobutylene, silicone rubber and other varieties. Used for interstitial sealing of structural joints.
