First, the system introduction:
Inorganic fireproof insulation board exterior wall fire insulation system, is the use of expansion type fireproof insulation material, inorganic non-alkali non-corrosion external wall fire insulation board adhesive as adhesive, with special mechanical anchor fixing parts to hang the fire insulation board On the wall, then apply the anti-cracking mortar, press the glass fiber mesh to form the structural protection layer, and finally add the outer wall fire insulation system with the outer layer as required.
Second, the main performance profile:
a. High flexural strength (0.2-1.0MPa/30-80mm thickness), high compressive strength (0.5-3.0MPa);
b. The thermal conductivity is small (0.05-0.065W/km) and can be adjusted according to the instructions;
c. Moderate weight (220-280kg/m3), can be adjusted as needed;
d. Absolutely no alkali and no halogen, fundamentally avoid the serious consequences of powdering, embrittlement and shedding after returning halogen and anti-alkali;
e. Double waterproofing, high softening coefficient (≥0.8), no immersion agent water immersion strength decreased by ≤10%, if added, the effect is better;
f. Freeze-thaw resistance, frost resistance (30 times), mass loss (%) ≤ 3 strength loss (%) ≤ 10
g. Dry shrinkage value (fast method) (mm/m) ≤ 0.3
h. Non-toxic, high temperature resistance, (>1300 °C, fully meet the A-class standard), no shrinkage after combustion, no deformation, no powdering, good sound insulation, good elasticity, heat-insulating flame retardant, no black smoke, high temperature and high flame Non-toxic gas after burning (according to the national standard AQ1);
i. Unique breathing material, prevent the accumulation of internal moisture, and the moisture absorption and condensation of water vapor formed during the process of alternating high temperature and low temperature, which leads to the disadvantage of the plate, effectively eliminating the safety hazards of the wall and the outer layer. ;
j. Stable performance, low cost, is a special adhesive (non-water glass) for making fire insulation boards, firewalls, etc.
Third, the selection range of the expanded refractory slurry main materials:
Expanded perlite, vitrified beads, foam glass, foamed pottery, expanded vermiculite, etc.
Fourth, the development trend of inorganic insulation materials
The application of inorganic thermal insulation materials in engineering, with the development of low-carbon economy in the future, China's building energy-saving requirements are getting higher and higher, and the application of inorganic thermal insulation materials will become more and more extensive.
