Products Description

Centrifugal glass wool is made of natural minerals such as quartz sand, dolomite, borax and other inorganic materials, which are mixed according to specific process formula requirements, melted at high temperature, and made by advanced centrifugal fiber-forming technology. Its products are divided into glass wool felt, Glass wool boards and glass wool tubes. Compared with other traditional thermal insulation materials, centrifugal glass wool has the advantages of light weight, high fire rating, thermal insulation, good sound absorption performance, high water repellency, corrosion resistance, and stable chemical properties.

The lot of people know that formaldehyde has very big influence to health, mainly shows aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction. What we call formaldehyde-free environmentally friendly glass wool is based on the traditional centrifugal glass wool, and partially adjusts the glass wool raw material formula and molding process, so that the raw wool is suitable for combining, curing, and molding with a new binder.

Products feature

The adhesive used is completely different from traditional glass wool and is an acrylic adhesive. It completely abandons toxic and harmful substances such as phenol, formaldehyde, and urea, so it is a revolution to traditional glass wool. It not only solves the problem of binder, but also solves the problem of solidification in the production process and the problem of production cost control.

The hydrophobicity of formaldehyde-free environmentally friendly glass wool is higher than that of ordinary glass wool, which can greatly reduce the possibility of the thermal insulation performance and service life of glass wool being reduced due to the infiltration of water vapor into glass wool. Hydrophobicity can reflect a technical index of the material's resistance to water penetration. It is expressed by the volume percentage of the non-permeable part of the sample after a certain flow of water is sprayed in a prescribed manner.

The fiber diameter of formaldehyde-free environmentally friendly glass wool is small, the diameter of glass fiber is much smaller than the national standard, and it does not contain slag balls, and the distribution is more uniform. Experiments have proved that under the same conditions, the smaller the fiber diameter, the smaller the thermal conductivity of the product, and the better the thermal insulation performance of the product.
