As a common functional material, rockwool has been widely used in construction and industry for its excellent properties such as fire resistance, heat insulation, sound absorption and sound insulation. In addition to pasting and fixing, rock wool can also be used for filling. Next, Utsen rock wool manufacturers to explain the rock wool block filling requirements.

First, the quality requirements of rock wool blocks

1, before filling the rock wool block, you first need to choose high-quality rock wool material. And in line with the relevant national standards, such as "building rock wool, slag wool insulation products" to ensure its quality and safety

2, rock wool block as a fireproof material, its fire performance is crucial. When selecting rock wool blocks, attention should be paid to their fire rating and melting point. In general, high-quality rock wool blocks should meet class A fire prevention standards, and the melting point is not less than 1000 ° C. Such rock wool blocks can effectively prevent the spread of fire and provide safe fire protection for the building.

3, the density of rock wool should be between 60-100kg/m³ to ensure its thermal insulation performance and compressive strength. At the same time, the moisture content should be less than 1% to prevent the thermal insulation performance from decreasing due to excessive moisture.

2. Filling construction requirements

1, preparation before construction: before filling the rock wool block, it is necessary to clean the construction base to ensure that the base is dry, smooth, and free from stains and oil stains. At the same time, it is also necessary to draw detailed construction drawings and be familiar with the relevant technical requirements.

2, filling process: when filling the rock wool block, it should be filled according to the design requirements. First, you need to determine the thickness and density of the fill, and then cut and splice according to the actual situation. In the filling process, it should be ensured that the rock wool block is evenly filled, dense and without gaps. In addition, it is also necessary to pay attention to the use of rock wool blocks with other fireproof materials to enhance the fire protection effect.

3. Check after filling: After filling, check the filling effect. Mainly check whether the filling is uniform and dense, and whether it meets the design requirements and relevant standards. If problems are found, rectification and repair should be carried out in time.

The use of rock wool blocks for filling needs to pay attention to two aspects, one is the quality of the product, the other is the construction standard.
