"EVB Thermal Insulation Mortar" uses EVB particles as light aggregate of dry-mixed mortar, which is premixed with high-quality cement, fiber polymer and modifier through scientific production technology to form a single-component inorganic thermal insulation and fire-proof dry powder mortar (patent number 20051015103.3). This product has excellent heat insulation, aging resistance, weather resistance and fire resistance.
EVB thermal insulation mortar has the following characteristics:
-Stable quality: All series products have been industrialized, raw materials have been optimized, and production procedures have been strictly controlled, thus fundamentally ensuring the consistency, stability and reliability of materials.
-Low cost: it can be directly constructed on the dry base surface, and the leveling layer and the insulation layer are combined into one, which greatly reduces the overall construction cost and has high cost performance.
-Good workability: The unique batching technology makes the product have good workability, easy scraping, low water absorption and good sag resistance during construction, which can greatly reduce the construction loss. Ordinary Plaster workers can be used for construction operation.
High efficiency: early strength and quick drying, simple process, greatly shortening the construction period.
-Good integrity: the thermal insulation system is fully bonded with the base to form a continuous whole without cavities, which ensures the firmness and safety of the thermal insulation layer. Site construction can be formed at will, especially suitable for special-shaped parts.
—— Fire prevention and insect prevention: The combustion performance of the material is Grade A, and it can withstand the high temperature above 1000℃. It makes up for the defects that organic thermal insulation materials are flammable and produce toxic gases at high temperature. Insect-proof and ant-corrosion-proof products are the first choice for internal insulation of stairwells and fire exits.
Long service life: excellent waterproof, sound-absorbing, breathable, waterproof, weatherproof and freeze-thaw resistance. The stability of inorganic materials can ensure that the system has the same service life as the foundation wall.
-Green environmental protection: a new type of inorganic material, non-toxic and non-radiation, is a real green building material, which not only creates value, but also purifies the environment and has excellent social benefits.
-Good comprehensive performance: light bulk density, good thermal insulation performance, no hollowing and cracking, strong adhesion and good cohesiveness. The system itself has high strength, and after taking appropriate strengthening measures, it can meet the requirements of decorative surfaces such as paints and tiles.
Application fields of EVB thermal insulation mortar:
1. This product is mainly used for internal and external insulation of walls, roof insulation and industrial insulation.
2, especially suitable for all kinds of brick-concrete structure, frame structure and shear wall structure of internal and external wall composite insulation and basement,
Public facilities such as garages, stair corridors and fire exits should be treated with fire prevention, heat preservation and heat insulation.
3. It is very suitable for thermal insulation of old houses and new rural construction, and can solve the problem of wall insolation.
The problem of high internal temperature is the first choice for internal insulation of external walls, stairwells and fire exits.
