Glass wool pipe is a professional insulation system for boiling water, steam, refrigeration and other pipes. Especially in refrigeration equipment, this kind of pipe is widely used.

　　（1） When the door is open, the length and width of the board are determined according to the position of the wall. Glass wool is priced in large spaces such as gymnasiums and workshops. In order to absorb sound and reduce noise, centrifugal glass wool is often used as the main sound-absorbing material. According to the need, it can be made into plate, column, cone or other special-shaped body. The inner part of the sound absorber is filled with centrifugal glass wool, and the surface is wrapped with sound permeable layer. Because the absorber has many sound absorption surfaces, the sound absorption efficiency is very high. After the glass wool board is melted, the adhesive is added to solidify the glass wool board. The diameter of glass wool plate depends on centrifugal extrusion process.

　　（2） Waterproof and moisture-proof: each glass wool board is packed in small plastic bags. Before installation, check whether there are damaged plastic bags, such as damaged small plastic bags, etc; The top of the glass wool board shall be covered with plastic cloth to prevent rainwater from penetrating into the glass wool board before bonding with stone, and aluminum foil shall be firmly pasted on the exposed glass wool board at the corner of the glass wool board with the same material as the glass wool board; The stone joint must be pasted with silicone rubber sealant.

　　（3） Prevent hot bridge. Glass wool tube is a common raw material in cold storage, large air conditioning and other refrigeration equipment.
