Q:How long is the fire endurance of the rock wool board?
In the fire safety rules, of the building materials are classified as non-burning combustion body, difficult to burn the body and burning body categories depending on its difficulty level of burning. Rock wool board is the fiber processed by the coated steel sheet and basalt minerals and other inorganic minerals,and the building panels through artificial composition. Because that the dominant sectors, like, steel plate and rock wool are non-combustible materials, so it should be considered as non-combustible component. The fire resistance of rock wool board has its judging criteria. Loss of support capacity, loss of integrity and loss fire insulation function. Its fire resistance is within 2 hours.
Q:What is the interior fireproof thermal insulation material?
polystyrene foam board, glass fiber spraying, polyurethane foam, thermal insulation system of inorganic wall. Use "DY" inorganic active thermal insulation material, have small thermal conductivity, large heat storage coefficient, better strength and achieve better thermal insulation and energy-saving effect when used in wall . Wall should definitely not crack and hollow because of high temperature in summer. It doesn't crack and shed because it is influenced by stress during heat expansion and cold contraction in cold winter.
Q:What defect does fused cast refractories have ?
The impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement.
Q:what is the requirements of roofing insulation materials fire rating?
The fireproofing requirements of architectural design are regulated by architectural design fire safety rules, roofing insulation material only has the requirements of materials combustion performance, namely non-combustible material. No fire rating requirements.
Q:What are the models of refractory cables?
There are bout four types. 1.NA-YJV / NB-YJV Crosslinked polyethylene insulated PVC sheath A (B) class fire-resistant power cable 2.NA-YJV22 / NB-YJV22 Crosslinked polyethylene insulated steel belt braiding PVC sheath A (B) class fire-resistant power cable 3.WDNA-YJY / WDNB-YJY Crosslinked polyethylene insulated polyolefin sheath A (B) class low smoke no halogen fire retardant power cable 4.WDNA-YJY23 / WDNB-YJY23 Crosslinked polyethylene insulated steel belt braiding polyolefin sheath A (B) class low smoke no halogen fire retardant power cable
Q:How to divide fire resistant level of fire door?
The classification of fire resistant level of fire door: Grade A is not less than 1.2h. Grade B is not less than 0.9h. Grade C is not less than 0.6h. It is suitable for fire door with different levels: Grade A: Equipment room (such as fire-pump room,power distribution room, generator room, smoke control fan room, etc) door, fire compartment, door on firewall; Grade B: Eclosed staircase, front door of stair room, smoke-proof staircase and fire elevator share lobby door, front door of fire elevator, household door which directly opens to front room or shares room; Grade C: The vertical shaft door, such as strong electric wells, weak electric wells, pipe shaft door and air conditioning facilities. I hope this information can help you.
Q:What are the construction fire-proof materials?
1. fire retardant coating 2. fireproof panel 3. fire proof and sealing material 4. flame resisting decorative materials 5. Green fire prevention materials
Q:Which refractory is better for building 1500 degree kiln ?
High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.
Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases or smoked?
If the outer packing is made of solid wood, it must be fumigated! If it is not solid wood, you can do without!
Q:What is the role of adding chromium oxide green in unshaped refractory materials
Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
