Q:What are the requirements on fire resistance period of C-level fireproof glass?
It can be classified into three types in terms of fire resistance, Class A: The fireproof glass which meets demands of fire integrity and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.
Q:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
You can add some animal hair, like bristles. After all, we don’t have so much hair. Remember not to use cement, because it will crack. Instead, make use of animal hair, lime, yellow mud and sand, after mixing up, and they would be firmer while in calcination.
Q:Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
The classification standards of B2-level fireproof and thermal insulation materials: 1. the national standard GB8624-97 classifies construction materials combustion performances into several grades, B2-level: combustible building materials: combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. 2.The exterior wall thermal insulation materials can be classified according to fire rating, insulation materials with B2-level combustion performance are: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.
Q:How to divide fire rating of decorating materials ?
Decorating materials shall be divided into four levels according to combustibility. Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability.
Q:What's the frequently used refractory material?
Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded magnesia-chrome bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory castables, etc.
Q:what is the fireproofing material of engine room? who knows it ?
1. The new type fire retardant coating in fire retardant coating, the expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder, etc. These inorganic component, is a major part of the thick coating type of fireproof coating, and they also are the major factor affecting the level of performance of fireproof coatings. The fireproofing thermal insulation properties of fireproof coating, is mainly determined by the fire back surface temperature of this factor, but also related to the fire endurance. If it reaches the same temperature for a longer time, it shows that it's fireproof thermal insulation is better, and the fire endurance therefore is higher. 2. The new fireproof board new fireproof board now is welcomed by the people and the important factor is its environmental protection, and with the increasing high-rise buildings, the fire protection requirements and strength requirements are also rising, it is a big challenge for the performance and standard of the fireproof board.. Now fireproof board is mainly used siliceous material or calcareous materials, and then mixed with the fiber material, lightweight aggregate, adhesives and chemical additives, it is not only be fireproofing, but also improve their thermal insulation performance, and light weight, good carrying capacity, good durability, no aging problem, more importantly, it is good in environmental protection.
Q:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
Well, you have no furnace to cast disposable molds. You can sieve sand which is used for blending cement with siever (left the most fine behind)! And then you can go to hardware (parts) factories directly with molds to ask them to pour. Remember that brass (60 copper) needs to be heated to 1200 ℃, while the crucible is not needed.
Q:What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
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:How long is the fire-fighting time of A class fire resisting window?
Duration of fire resistance of A class fire resisting window is not less than 1.2 hours; B class window is not less than 0.9 hours. And when install fire window, you must use Level to correct or use hanging line method to correct verticality of four directions, making its same horizontally anf vertically. Window frame must be integrated with the building, using wooden or metal parts connected to the wall. After steel frame is installed, cement mortar must be watered between window frame and wall , and is maintained more than 24 hours before normal use.
