Release time: 2019-01-07

Today, rock wool composite board manufacturers summarize some tips for you on the selection and purchase of composite boards. I hope you must pay attention when you buy the board to prevent being cheated when buying in the market. Then let's learn the tips for selecting composite boards.

1. Appearance quality: the surface is smooth, and there shall be no scars, stains and damages that hinder the use.

2. Combustion performance: combustion performance refers to all physical and chemical changes that occur when building materials burn or encounter fire. The performance is measured by the fire resistance of the material surface, the spread of flame and the production of toxic substances.

3, thermal load shrinkage temperature: thermal load shrinkage temperature is used to characterize the wet and thermal stability of rock wool composite board, is to soak the wet composite plate sample in gradually heated water, the plate will begin to shrink when the temperature reaches 643 degrees, so the load shrinkage temperature of the plate is 643 degrees, that is to say, the plate will deform when the outside temperature reaches 643 degrees.

4, hygroscopicity: hygroscopicity refers to the nature of the material in the air can absorb moisture. The nature of the composite plate and the chemical composition of the raw material are related to the structure. As for inorganic non-metallic materials, in addition to the chemical properties of the surface of the material, it is also related to the structure formed by the material. If the hairy pores, its moisture absorption capacity is relatively strong, in addition to the diameter and structure of the capillary pores.

5. The important content of the composite board is that the density range of the composite board is kg/m 3 100-250-15%, and the rock wool composite board in this density meets the product quality requirements.

It has low energy consumption in production, and the energy-saving effect shown in the process of being used is quite obvious. It also has the characteristics of soil saving, land saving, environmental protection, waste utilization, heat insulation, heat preservation, fire prevention, light weight, reduced transportation cost, convenient construction and low cost.

The number of new energy-saving building materials products is increasing step by step, such as green paint, energy-saving and water-saving sanitary products, environmentally friendly stone, environmentally friendly exterior wall tiles, etc.

The above is about the rock wool composite board related content, I hope to help everyone.
