What is asbestos - free fibre-cement?

The main difference between asbestos-free fibre-cement slabs and cement fibreboard slabs is that one has organic mineral fibers in it called asbestos and the other doesn't. China is a major producer of asbestos products, in the country has two sets of industry implementation standards, European and American countries are not, so the use of European and American countries asbestos products is not safe, at the same time they do not allow the import of products containing asbestos. After scientific examination in China, it has been confirmed that the use of chrysotile asbestos building materials is harmless to human body. So allows you to use at home, no asbestos fiber cement in non-asbestos inorganic mineral fiber, organic synthetic fibers or cellulose fibre, alone or mix as reinforced material, adding silica with ordinary Portland cement or cement, calcium material instead of part of the cement gelled material, the production after pulping, molding, high compression and high temperature steam. It has the characteristics of fire and damp proof, heat insulation and weather resistance. Asbestos-free fiber cement board is similar to the use of fiber cement board, 4-6mm is often used for building ceiling ceiling, 8-12mm is mostly used for building partition or decoration, the thicker can be used as sandwich board, through asbestos-free fiber cement board as the base material can be made into a variety of building materials whether function or decorative are very good.


Product introduction

I. production process: the asbestos free fiber cement board is made of Portland cement, natural inorganic mineral fiber and plant fiber as raw materials, with addition of silica-calcareous materials and a variety of flame retardant materials modified, through pulping, molding, ten thousand tons of press pressure, high temperature autoclaved curing.

Ii. Product features

1. Fire insulation: non-combustible grade A, the board will not burn in case of fire and will not produce toxic smoke; Low conductivity makes it an ideal insulating material.

2. Waterproof and moisture-proof: in semi-open air and high humidity environment, it can still maintain stable performance without sinking or deformation.

3. Thermal insulation and sound insulation: low thermal conductivity, good thermal insulation performance, high product density, good sound insulation.

4. Light weight and high strength: the plate pressurized by the 7000-ton flat oil press is not only strong, but also not easy to deform and warp; Small weight, suitable for roofing ceiling and other aspects.

5. Simple construction: dry operation, simple installation and construction of keel and plate, fast speed. Deep - processed products also have the characteristics of simple construction and better performance.

6. Economic and beautiful: light weight, combined with the keel, effectively reducing the cost of engineering and decoration; Uniform color appearance, smooth surface, direct use can make the building surface color unity.

7. Safe and harmless: it is lower than the national "radiological protection standard for building materials", and the measured index is equal to that of the lawn around the building.

8. Long service life: acid and alkali resistance, corrosion resistance, will not be damaged by moisture or insects and ants, and the strength and hardness with time, to ensure a long service life.

9. Can be processed and second decoration performance is good: according to the actual situation for sawing, drilling, carving, drilling nails, painting, paste tile, wall cloth and other materials.

Iii. Application scope:

Mainly used in shopping malls, hotels, hospitals, new residential, renovation, entertainment venues, all kinds of industrial and commercial buildings and civil buildings. Construction units, designers, according to the specific circumstances of the project to choose the product. Asbestos-free fiber-cement board has been widely used in Beijing, shijiazhuang, Hohhot, baotou, tianjin, Shanghai, guangzhou, xi 'an, dalian and other first-tier and second-tier cities. Main specifications 1220*2440*8mm if the customer needs other format size, the enterprise can take the place of cutting, special specifications can be scheduled processing. If there is any technical problem, please contact our company in time.
