Glass wool board is a commonly used insulation material, which has the characteristics of lightweight, heat insulation, sound insulation and fire protection, and is widely used in construction, industrial equipment and pipelines. However, when purchasing glass wool board, how to judge its quality is a problem that needs to be considered. Utesen glass wool manufacturers will introduce how to buy high-quality glass wool boards.
First, the quality of the object
When buying glass wool board, you first need to observe its physical quality. A high-quality glass wool board should have the following characteristics:
1. Regular appearance: The appearance of glass wool board should be smooth and neat, without obvious concave and convex, deformation and other phenomena.
2. Uniform texture: The high-quality glass wool board has accurate size, uniform radial distribution of thickness, width and fiber, soft and delicate feel, and no obvious graininess.
3. Uniform color: The color of high-quality glass wool board should be uniform and consistent, and there is no obvious color difference.
2. Parameter indicators
In addition to the physical quality, the parameter index is also one of the important criteria to measure the quality of the glass wool board. Here are a few important parameters:
1. Thermal conductivity: Thermal conductivity is an important indicator to measure the thermal conductivity of materials, and the thermal conductivity of high-quality glass wool board is relatively low (at room temperature, 0035W mk), good thermal insulation performance.
2. Combustion performance: high-quality glass wool board has Class A non-combustible combustion performance, which ensures that toxic gases and a large amount of smoke will not be produced in the fire.
3. Moisture content: Moisture content is an important indicator to measure the moisture absorption performance of materials, and the moisture content of high-quality glass wool board is relatively low (moisture content is less than 1%), and it is not easy to be deformed by moisture.
4. Fiber diameter: The diameter of glass wool fiber is generally below 10 microns, the smaller the fiber diameter, the higher the production process, and the fiber diameter of high-quality glass wool board is small and evenly distributed.
5. Slag ball content: Slag ball content is one of the indicators to measure the content of material impurities, and the slag ball content of high-quality glass wool board is relatively small or even no slag ball.
Third, brand reputation
When purchasing glass wool boards, it is recommended to choose a brand with high visibility and good reputation. These brands usually have the following characteristics:
1. Strong strength: well-known brands usually have strong strength and scale, and can invest a lot of money and manpower in R&D and production to ensure product quality.
2. Quality assurance: Well-known brands usually pay attention to product quality and reputation, and have strict control over the production process and quality standards of products, which can ensure the quality of products.
3. High-quality service: Well-known brands usually provide perfect after-sales service, such as technical support, after-sales service, etc., which can provide consumers with better services.
4. Certificate and test report: Well-known brands usually provide product certificates and third-party test reports related to glass wool board to ensure compliance with national and industry standards.
The purchase of high-quality glass wool board requires us to pay attention to the physical appearance, parameter indicators, brand and other aspects of the product, and at the same time, we must also combine our own project situation and budget to select the most cost-effective one.
