What are the identification methods for the quality of fireproof and thermal insulation materials ro

Rock wool board is made of basalt and other natural ores as the main raw materials, melted into fibers at high temperature, added an appropriate amount of binder, and cured and processed, which belongs to fireproof and thermal insulation materials, and due to the current improvement of fire protection requirements, the material has been used in a certain range of thermal insulation projects. In the face of the current complex and chaotic exterior wall insulation market, how to identify the quality of rock wool board insulation materials in my selection.

For the identification method of the quality of fireproof and thermal insulation material rock wool board, we can distinguish it from the following two aspects.

1.Rock wool board color.

Judging from the color of the cotton, whether it is the same, whether there is a difference between white and yellow. Then there is whether the distribution of the glue is even, and whether there are any glue blocks. The slag content is not to be able to see a lot of large slag with the naked eye.

The good thing is that the color is the same, yellow, the glue is evenly distributed, and the cotton filament is fine, and there is a lot of slag on it that is not visible to the naked eye.

2.Bulk density of rock wool board.

The bulk density of qualified rock wool board is generally 120 130kg cubic meters. The above identification methods for the quality of fireproof and thermal insulation materials rock wool board are for reference only, if there are any deficiencies, please point out the exchange!

I haven't heard of this manufacturer you are talking about. The real rock wool board has no feeling of pricking to the touch, with a smooth appearance, uniform compactness, good strength and greater toughness. The side-cut cotton silk is S-shaped, which is stirred together, which is caused by the unique process of large-scale production lines in order to increase the pulling force, and the water absorption rate is relatively small.

The rest of the performance can only be tested by the equipment.

Weigh the volume, see if it's enough, if it's enough, it's okay, Cathay has not heard of the good ones are Huaneng, Qiyuan, Owen, Si Corning.

In house construction, insulation works are a key focus. In the insulation project, we often use a material called "rock wool insulation board", which not only has good thermal insulation performance, but also high temperature resistance and long service life. What are the quality requirements for rock wool insulation board?

1. The thermal insulation should be good, and the relevant requirements of the construction must be met;

2. The stability should be good, it must be firmly pasted with the base layer of the wall, the impact resistance should be strong, and it should be able to resist the invasion of storms, rain and snow;

3. The durability should be good, it is the average service life should reach at least 25 years, the water tightness should be good, and the waterproof performance should be good.
