Application of microsilica fume in thermal insulating material

microsilica fume in thermal insulating material

Microsilica fume is a very active raw material. After adding, it can greatly improve the quality of the project. Especially in improving the strength and early strength of the project, the effect is obvious. Micro silica fume powder was spherical under the microscope, after adding water, generating hydrogel under the water action, showing network chain structure, can play the role of wrapping water. Under the external force, the water can be released, and the cement can be hydrated and the strength can be increased.

Compared with calcium potassium carbonate, the micro silica fume can replace it completely in thermal insulation materials, and has absolute advantages in many aspects: the price is only 1 / 5 of calcium potassium phosphate, which can better guarantee the later strength of the project. The dosage of microsilica fume is about 3% – 10%, which can greatly improve the quality of the project. Thermal insulation material is very widely used, mainly used in:

1, wall insulation polymer mortar, thermal insulation mortar, interface agent.

2. cement based polymer waterproof material.

3, light aggregate heat preservation and energy saving concrete and products.

4. The interior and exterior walls used putty powder.
