Fiber cement board price, specification, size, thickness, construction, installation, use, manufacturer density and strength consultation 1301150664
. Product is light: made of fiber Cement boards are used as partition walls, and the weight is only 1/2 of a brick wall of the same thickness, and 1/2 of a block wall, which is beneficial to the structure's earthquake resistance, and can effectively reduce the cost of the foundation and main structure.
. Thermal insulation: Since the fiber cement board uses Portland cement and plant fiber structure, its thermal conductivity is ./(.), which is almost the same as the gypsum board, and is similar to the lime sand brick block (.(.) )), its thermal insulation performance has significant advantages.
3. Good fire resistance: Because the fiber cement board itself is non-combustible, and will absorb a large amount of heat during the combustion process when exposed to fire, delaying the increase in ambient temperature, therefore, the fiber cement board has good fire resistance and flame retardancy. performance. Tested by the National Fire Equipment Supervision and Inspection Center
The fire resistance limit of fiber cement board partition walls can reach up to 2 hours. If it reaches the first level of fire resistance, the gypsum board can only reach the third level of fire resistance. The fire resistance of fiber cement board has passed the wet two-hour fire resistance test.
.Good decorative function: The fiber cement board has a smooth surface, and the seams between the boards form a seamless surface, and the surface can be directly decorated. Because the exterior and interior are the same, many seam processing methods can be used to show your noble side. The two sides have different textures. The fine side can be directly painted, and the rough side has a unique texture and can be directly applied with ceramic tiles and other materials. It has high strength.
.Good constructability: With only woodworking tools, fiber cement boards can be cut, perforated, and polished at will. The construction is very convenient. When used for decoration, traditional wet methods and dry hanging operations can be used, which is very convenient. Greatly improve construction efficiency.
.Comfortable living function: Because the fiber cement board has a unique and natural cement pore structure, it can adjust the indoor humidity within a certain range, making living comfortable. The unique clear water effect on the surface gives people a refreshing feeling and highlights your unique taste.
High strength: The flexural strength of fiber cement board reaches 3/ (vertical), / (horizontal), and the bending failure load: (vertical), (horizontal)
. Space saving: use fiber cement board When used as a wall, the thickness of the wall can be greatly reduced, and the sound insulation and fireproof performance of the wall can be guaranteed. What’s more, it has convenient construction and unique texture design.
.Complete specifications: The specifications of fiber cement board are:**

. Calculate density: The quality of fiber cement pressure board is closely related to its density. Users can according to the board Use the weight to determine whether the board is good, whether it is fiber cement pressure board or calcium silicate board. The density of the regular board (-) of the high-quality fiber cement pressure board board is about ./3, the weight of the best board in the natural state is about ./, the density of the thick board is about ., the weight of the best board in the natural state is about / about. The density of ordinary cement or pressure-free board is about ./3, and the weight is about ./. The density of calcium silicate board is around ./3 and around 3./.
Ask about special specifications:
manufacturers without presses can only produce ordinary cement boards with -thickness. Manufacturers with small presses cannot produce ultra-thin boards and ultra-thick boards. They cannot produce ultra-thin boards and ultra-thick board products. Manufacturers explain that their presses are too small or even have no presses at all, and naturally they cannot produce the best fiber cement pressure panels.
Choose the most powerful manufacturer: Buying from the manufacturer can prevent unscrupulous merchants from substandard goods from other manufacturers. Contact several manufacturers to inspect the strength of the manufacturers on the spot and compare them to buy the best products. When choosing a manufacturer, it depends on the manufacturer's scale, strength, management model, etc., especially whether it has ultra-thin plates and ultra-thick plates in stock. Avoid small workshops or family-managed businesses. Stock cement boardr>Roofing cement board. />Fiber cement board constructionr>
