What is the most common thermal insulation material used in light steel structure villas is fiberglass wool and rock wool? What is the difference between the two production processes, performance, service life, etc.? Is it good or bad? Fiber glass sandwich panel supplier share with you:
First, glass fiber wool and rock wool are different in raw materials and processing technology
1. Raw materials and technology of glass fiber wool
The main raw material of fiber glass sandwich panel is glass, which is mixed with other auxiliary materials in a certain proportion and put together in a glass melting furnace. The melting operation is not started. The melted solution will leak. The screening of the plate separates the impurities and is finally sent to the centrifuge. The centrifuge is fully powered and runs at a high level. Through the force of rotation, the glass is thrown into a thin stream of glass. The flow will be formed-all kinds of fibers. At the same time using the atomizing adhesive, due to the negative pressure wind of the poly cotton mesh belt, the chemical fibers adhered to the epoxy adhesive adhere to the moving mesh belt, resulting in a symmetrical Cotton felt.
Finally, the product is cured and shaped by a constant temperature curing oven, and cut according to predetermined specifications. The cut product can be sold after packaging.
2.Raw wool raw materials and technology
The main material of rock wool is fine basalt. After being melted into a solution at high temperature, it is sent to the centrifugal equipment to assist other materials with different proportions to make common insulation materials.
Fiber Glass Sandwich Panel China
Depending on the application of rock wool, different specifications can be made. Such as rock wool tube shell, rock wool board, rock wool seam felt and so on.
Second, the acoustic performance difference between glass fiber wool and rock wool board
Fiber glass sandwich panel china and rock wool both have good sound insulation, but their acoustic performance is different. Generally speaking, the sound insulation effect of 24kg / m3 glass fiber wool is equivalent to 80kg / m3 rock wool. (In the practical application of light steel villa construction, the effect of glass fiber wool is much better than that of rock wool. Because, even with the same sound insulation effect, glass wool can be much lighter.
Differences in hydrophobic performance between glass fiber wool and rock wool board
1.Hydrophobic performance of glass fiber wool
Glass fiber cotton is not easy to break due to soaking and rain, and it is easy to dry when it is invaded, and its characteristics are stable.
2. Hydrophobic performance of rock wool
The rock wool immediately collapsed after being infiltrated and lost many characteristics.

2. Hydrophobic performance of rock wool
The rock wool immediately collapsed after being infiltrated and lost many characteristics.
Fourth, the difference between the service life of glass fiber wool and rock wool board
1. The service life of glass fiber wool Glass wool has stable performance. Generally, it will not be powdered and its performance will decrease sharply. Its service life can reach 30 years.
2.The useful life of rock wool
Rock wool is easy to smash. After a period of time, the slag ball will fall off or even disintegrate. Its service life is generally about 10 years.
