Q:what is the specs of thermal insulation refractory slab ?
Fireproof insulation specification is 1220 * 2420 1220 * 2420 * 8 * 9. HPL also known as the fireproof board is scientificly named thermosetting resin impregnated paper laminated wood, the abbreviation of which is HPL.Decorative high-pressure Laminate is fire-resistant building materials for decorative purposes. It is rich in surface color, texture and special logistics performance, widely used in interior decoration, furniture, kitchen cabinets, laboratory table, external walls.
Q:What is the the best ratio of mortar in refractory cement?
The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
Q:What's the A class fireproof and thermal inuslation matertial for external wall?
It is a kind of green and environmental protection inorganic material, free of harmful substances like asbestos, benzene, formaldehyde, etc. Its fire resistance can be up to A1grade non-combustible material, which means it can endure the highest temperature of 1400 ℃. It is thermal insulating with low heat conductivity and high heat storage coefficient. It has good weather resistance, finished product stability, anti hollowing, crack resistance, wind pressure and shock resistance with the same service life as buildings of 70 years. It is water-fast and moistureproof, breathable but waterproof, and fungusproof without influence from steam. It is convenient in construction which omits many procedures of panels construction. Once the second plastering is finished, the construction is completed, which greatly shortens the construction period. It has good adhesive property with various base planes, and meanwhile its external exposed surface can choose coating, facing brick, aluminum sheet, marble, etc. It saves money. Excellent construction technology reduces the construction cost. It effectively prevents the panels from leakage at the external wall, window, eave, etc. which saves the subsequent maintenance fund. It provides timely delivery. With sufficient supplies of raw materials and convenient production, it is fast in delivery.
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:Is refractory material harmful to human body?
Part is harmful to human body, mainly refractory raw material, silica powder inhalation can cause lung tuberculosis, siliceous fiber on the human body does have great harm, in fact, like other inorganic fiber in the inhalation of the trachea or lung after the same harm to human
Q:What are the raw materials of refractory? And what are their names?
Q:How long is the duration of fire resistance that fireproof door of level B can endure?
Fireproof doors can be divided into three levels, namely level A,B,C. Fireproof doors of level A can endure fire for 1.50~2.00h while level B for 0.50~1.50h. However, according to national condition, the lowest fire doors fire resistance limit has been specified, namely, level A,1.50h;level B,1.00h; level C, 0.50h.
Q:what's the varieties of fire-proof sealing material?
Fire blocking material currently on the market include: fire stopping board, foam blocking material, flame resisting module, fire-resisting sealant, flexible organic caulking, WXY-II and fire retardant bag, etc. fire-proof sealing material is widely used in building construction and can ensure high-temperature flame and smoke from fires not spread to another fire compartment, different buildings generally use different sealing methods. Pipeline is generaly sealed by pouring concrete board or mortar.
Q:What are the advantages of refractory material?
Jingute WHL type, GDS type
Q:What's the poured refractory material?
According to the volume density, it can be classified as follows: Heavy (>2.0g /cm3), medium heavy (1.0-2.0g/cm3), light (0.4-1.0g/cm3); classified by binding agent: hydraulic bond, chemical bond, coagulation binder, hydraulic and coagulation binder; classified by material: material of clayey, high alumina, silicious, magnesian, alumina-magnesia, magnesian-chrome, magnesia-zirconia, silicon carbide-based, etc.
