Centrifugal glass wool, as a kind of multifunctional material, is widely used in fire prevention, heat preservation, sound insulation and other fields. Centrifugal glass wool bulk density (density) is an important parameter, which is directly related to the performance and use of glass wool. Centrifugal glass wool bulk density standardization can ensure product quality consistency, improve industry competitiveness and facilitate quality management and supervision. Next, Utsen insulation material manufacturers will explain to you the national standard for centrifugal glass wool bulk density.
According to "glass wool and its products for heat insulation", the types of glass wool products are divided into ordinary glass wool products, high temperature glass wool products, hard glass wool products, formaldehyde-free glass wool products, and water-repellent glass wool products. According to the shape division, glass wool can be divided into glass wool board, glass wool felt, glass wool blanket, glass wool tube shell, glass sliver, each classification has different standards for volume weight.
First, ordinary glass wool products
1, glass wool board
The nominal density shall not be less than 24 kg/m3, and the allowable deviation of inch and density shall comply with the provisions of Table 1.
2, glass wool felt
If the nominal thickness is less than 60 mm, the nominal density should not be less than 12 kg/m3, and if the thickness is greater than or equal to 60 mm, the nominal density should not be less than 10 kg/m3. Thickness dimensions and density deviations shall comply with the provisions of Table 3.
3. Glass cotton blanket
The bulk weight of the glass cotton blanket has not been made relevant requirements, but there are deviation requirements.
4. Glass wool tube shell
There are no relevant requirements for the bulk weight of the glass wool tube shell, but there are deviation requirements.
Two, high temperature glass wool products
The nominal density should not be less than 38 kg/m3. The size and density deviation of high temperature glass wool board shall comply with the provisions of Table 1, the size and density deviation of high temperature glass wool shall comply with the provisions of Table 3, and the size and density allowable deviation of high temperature glass wool tube shall comply with the provisions of Table 7.
Third, hard glass wool products
1, glass wool board
The nominal density should not be less than 48 kg/m3. Size and density deviations shall comply with Table 8.
2, glass cotton strip
The nominal density should not be less than 32 kg/m3. Size and density deviations shall comply with Table 9.
The national standard of centrifugal glass wool bulk density is an important basis for ensuring product quality and performance. In actual production and application, national standards should be strictly observed, and reasonable adjustments should be made according to specific needs to achieve the best performance.
