Introduction of fireproof and thermal insulation system for expanded refractory slurry board

1, system introduction

Intumescent refractory slurry fireproofing and heat preservation system technology uses expanded mineral refractory granules, and uses Jinling brand inorganic alkali-free and non-corrosive exterior wall fireproof thermal insulation board adhesive as adhesive, which will be fixed by special mechanical anchor fixing parts. The fireproof insulation board is attached to the outer wall, and then the anti-cracking mortar is applied, and the glass fiber mesh cloth is pressed to form a structural protection layer, and finally the outer wall fireproof insulation system of the outer layer is added as required.

2, 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, no halogen, fundamentally avoid the serious consequences of powdering, embrittlement and shedding after returning halogen and anti-alkali;

e, double waterproof, high softening coefficient (≥0.8), no watering agent water soaking 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 powder, 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. The unique breathing material prevents the accumulation of internal moisture and the moisture absorption and condensation of water vapor formed during the alternating process of 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 and low cost. It is a special adhesive for making fireproof insulation boards and firewalls (non-water glass).

3. Selection range of intumescent refractory slurry main materials: expanded perlite, vitrified microbeads, expanded vermiculite, etc.
