Q:How is grade of fire endurance divided?
Fire resisting shutter is divided into Class A / B / C, and the relevant fire endurance are not less than 1.2 /0.9 /0.6 hours, see "General technical conditions for steel fire resisting shutter GB 14102-93". 4.3 4.3.1 Classification according to time of fire resistance 4.3.1 Ordinary steel fire resisting shutter (see Table 3) Table 3 and Category Code Refractory time hF1 1.5F2 Composite steel fire resisting shutter (see Table 4). Table 4 and Category Code Refractory time hF3 2.5F4 3.04.4 Classification according to refractory time and smoke prevention performance 4.4.1 Ordinary steel fire and smoke resisting shutter (see Table 5) Table 5 category and code refractory time h smoke leakage (20Pa differential pressure) FY1 1.5 ≤0.2m3 / m minFY2 2.0 ≤0.2m3 / m min4.4.2 composite steel fire and smoke resisting shutter (see table 6) table 6 category and code refractory time h smoke leakage (20Pa pressure) FY3 2.5 ≤0.2m3 / m minFY4 3.0 ≤0.2m3 / m min Excerpt completed. Fire shutter used as fire compartment has a fire resistance of 3 hours, and fire shutter set on the upper opening part on the firewall has a fire resistance of 1.2 hours. **** Materials with fire resistance of 3.0 hours are called AAA refractory material (back fire surface). "Building Conventions" have mentioned in places where it is really difficult to set a firewall, fire shutters can be used to separate fire compratment. When using fire shutters whose back surface temperature rise is included as the judging criteria of fire resistance, its fire resistance should be not less than 3.00h; When using fire shutters whose back surface temperature rise is not included as the judging criteria of fire resistance, independent protection of closed automatic water spraying system should be set on the both sides of the shutter, and the duration of water spray should be not less than 3.00h. In summary: Fire shutter is divided into: Grade AAA, A, B and C
Q:Who knows about roof fireproofing materials?
Roof thermal insulation materials are various which generally can be divided into two categories, namely inorganic and organic materials: Inorganic materials are expanded perlite, aerated concrete, rock wool, glass wool, etc. Organic materials are styrofoam, polyurethane foaming plastic and so on. A. common roof thermal insulation materials 1. the expanding polystyrene board (EPS) has good thermal insulation performance, and cheap price but poor intensity with heat conductivity coefficient of 0.038-0.041. 2. extruded polystyrene board (XPS) has better thermal insulation performance and high intensity but an expensive price with heat conductivity coefficient of 0.028-0.03. It is moisture resistant but needs treatments on surface in construction. 3. rock wool board, with heat conductivity coefficient of 0.041-0.045, is fireproofing, fire retardant. It has a good hygroscopicity performance but is poor in thermal insulation. 4. gelatine powder polyphenyl granule heat insulating slurry, with heat conductivity coefficient of 0.057- 0.06, has a good flame resistance performance, but the results of recycling and thermal insulation are unsatisfactory. It has high construction requirements. 5. polyurethane foaming material, with heat conductivity coefficient of 0.025-0.028, has good waterproofness and thermal insulation performance, as well as high intensity, but it is expensive. 6. perlite and other slurry, with heat conductivity coefficient of 0.07-0.09, have good flameproofness and water-absorbing ability but are poor in thermal insulation and thermostability.
Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
2, form Mg-SiO2 coagulation and combination, CA cement bond? Bricks can generally be made by combing with phenolic resin, castable use 1, combined with silicon powder; 3, can also combined with brine MgCl is binding agent
Q:What do refractory materials include?
What refractories are included? Refractories include AZS brick, corundum brick, direct-bonded magnesia-chrome, carborundum brick, silicon nitride bonded silicon carbide brick, non-oxide refractory materials such as nitride, silicides, sulfides, borides and carbides, oxidation calcium, chromium oxide, aluminum oxide, magnesium oxide and beryllium oxide.
Q:How long is the fire resistant limit for ultra thin fire retardant coating?
There is no detailed stipulation for ultra-thin fire retardant coating, and the thickness of the inside is the fire resistance limit shall reach certain time(at least). In engineering, the thickness of the fire retardant coating is generally determined according to the manufacturer's testing report. We use thin fire retardant coating for steel structure: if the fireproof limit is 2.5 hours. the thickness should be 4.9mm. If fire-resistant limit is 2 hours, the thickness shall be 3.5mm. If the refractory limit is 1.5 hours, the thickness shall be 1.75mm. If the limit is 1.0, the thickness is 1.17mm hope my answer can help you

Q:What kind of material is refractory fiber?
Refractory fiber, also known as ceramic fiber, is fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts.
Q:What material is refractory material?
Basic refractory materials, basic refractory, CaO, basic, MgO style alkaline earth oxide. The refractory materials mainly refers to magnesia refractories, dolomitic and lime refractory refractory. Main categories: (1) strongly basic magnesite brick, magnesia carbon brick, limestone and dolomite brick refractory materials;(2) alkalescent magnesia chrome refractories, forsterite refractory, magnalium and magnesia-chrome spinel refractory, basic refractory materials, high-temperature caustic slag, alkaline solvent resistance, strongly acidic slag flux or acidic refractory. The reaction is mainly used in steel furnace such as colour metal smelting furnace and cement kiln.

1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire retardant coating; 9. fire-proof sealing material.
Q:What is refractory?
Refractory is an inorganic nonmetallic material with minimum refractoriness of 1580 ℃. Now, refractory is not defined merely by judging that whether its refractoriness is at above 1580 ℃. Currently, refractory, an inorganic nonmetallic material, are widely used in metallurgy, ceramics, power and other industrial fields.
