Product Description
Product name:9mm 10mm 12mm Fire Rated Magnesium Oixde Tunnel Board
Product type:D-HC-2.0-12 D-RABT-3.8-20 D-ZH-2.0-10
Specification:GB28376-2012<tunnel fireproof protection board>
Product introduction:
Type of the D-HC-2.0-12, top of the tunnel fireproof board is our company third generation product. The first generation product is based on inorganic keel, insulation layer, inorganic board of horizontal separating elements. The second generation product develop sheet of fire resistance, water-proof structure and formula, It is based on the double-plates staggered directly install process, fire resistance and physical properties are suitable for underwater tunnel, access to the fire resistance, waterproof, solid structure, nicely decorated, and quickly to install, the affordable good results. The third generation product is more economical for a highway tunnel fireproof protection board.The products are mainly high-strength silicate, expansion perlite, mica, glass fiber and other inorganic materials, products are pressed and conservation, high temperature steam curing,drying,cutting, and molding, which is fire-resistant, lightweight, free from environment temperature, humidity limit construction,. It is the best choice of fireproof material by Four seasons installed roads, mountains and underground, and underground tunnel.
Main features:
1, Fireproof performance: homogeneous material, class A1 non-combustible performance material, when sheet thickness is 20mm, its time can reach to 3.83hours according to fire resistance RABT standard.
2, Light weight: dry density is only 900/m3, its an extremely safe ceiling materials.
3, Weather resistance: comply with the requirements of anti-acid, anti-alkali, heat and humidity resistance,salt fog resistance,freezing and thawing resistance and other standards.
4, Meet the durability of service life more than 20 years.
5, Seismic and sound absorbing:when driving , the piston wind pressure it will not be loose,due to the micropores formed by the structure of the plate, it has a good sound -absorbing effect.
6, Environment protection:it is made of inorganic material and water, by high temperature, high pressure steam curing, conservation, non-asbestos and no-radioactive hazardous materials, when it burns, it won't have toxic, which is an extremely environmentally friendly products.
7, Construction environment: when it is under construction, it won't have special requirements for environment temperature, humidity, ventilation, dry operating, and without any pollution damaging effects on the environment.
8, Quick construction: one time job is complete, don't need back and forth to repeat the operation, nor do they need secondary decoration job, 8-10 times faster compared with fire retardant coating .
9, Economy: fire resistant coating is the original fire safety products in the eighty of the last century, because fire retardant coating needs to be prepared in the field, produced by a large number of the bricklayer, so it is not stable and high labor costs, while tunnel fireproof board is stable products of the factory, its advantage is :stability, and the price is cheaper than coating.
fireproof partition fireproof resistance 1-4 hours using table 1:

Applications:
Xinlong tunnel fireproof boards are mainly used for road, mountain tunnels, and suitable for the standard of RABT and fire resistance 3.83hours.Also used for the type I and type II tunnels, and non-load-bearing structure of the tunnel fire protection.
Top of the tunnel fireproof classification and the boards selected:
1,Tunnel of the first level:fire resistance time is 3.83 hours(according to the standard of RABT), two pieces of 11mmfireproof boards stagged to install.
2,Tunnel of the second level:fire resistance time is 3.3 hours(according to the standard of RABT),two pieces of 10mm fireproof boards stagged to install.
3,Tunnel of the third level:fire resistance time is 2.0 hours(according to the standard of HC temperature rising curving),two pieces of 10mm fireproof boards staggered to install.
