FOREX US rock cement board cement board FOREX FOREX, FOREX plate, Shanghai US rock cement board, wood fiber cement board, magnesium oxide board sales, the United States slab, wood fiber board, sales WWCB US rock cement board production and processing US rock cement board, wood fiber cement board wood fire performance ingredients produced after mineralization by toxic chemicals. These mineralized wood components treated with the combination of Portland cement base, increasing its strength and toughness, so that the sheet has distinct structural features, and both Portland cement quality: fire, moisture, corrosion, pest control, and durable. Overall structural WWCB of it has impact resistance and easy processing. Because of compact, high-density, WWCB excellent sound effects, and affordable, and Portland cement lignocellulosic materials combine to produce a non-toxic building materials plate, it does not contain any volatile toxic substances, such as asbestos and formaldehyde. WWCB does not produce any harmful substances, excellent environmental performance. WWCB containing 71% Portland cement, 19% of mineralized wood fiber, 9% water and 1% of the adhesive. WWCB comply with ASTM E 136 standard non-combustible construction materials, structural performance excellent. Water immersion is not hierarchical, uniform stability. WWCB can be cut, planing, grinding, drilling, threading, and you can use nails or screws. WWCB having a non-directional characteristics, regardless of how to install, very easy. WWCB as a high-quality fireproof floors and decorative materials based on their unique physical characteristics, WWCB can be used in some high-quality decorative areas, such as long demanding fire regulations and the conditions of the regions and meet waterproof, moisture requirements. Fire WWCB can be used in some high-quality decorative areas, such as long demanding fire regulations and the conditions of the regions and meet water and moisture requirements. WWCB is a non-combustible decorative materials, has passed ASTM E 136 strict requirements. It has a zero flame spread and zero smoke spread limit. walls and flooring are 1-2 hours of fire resistance of easy reach. Strong impact resistance is strong impulse to fight other decorative materials having WWCB incomparable material, including airports, hospitals, prisons, or other places need to be very durable. Sound effects due to its high density 1300KG / cubic meter, when WWCB protective layer for wall or floor, it has a very good acoustic. The following is WWCB for walls, ceilings and floors when STC. Such as adding iron frame plates between the wall and the wooden frame panel walls WWCB, sound better. Join WWCB hollow joists or wall plates, will have the same effect. Weather resistance and durability WWCB had used around the world in different climate zones, weather resistance and durability in the United States and Europe have been a number of agencies to verify eligibility.
