- Q: Is refractory material harmful to human body?
- Chromium oxide is poisonous in alkaline environment, and the gas produced by heating of asphalt, asphalt and refractory material is poisonous............ Go to the real estate company experts, I can think of these
- 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 2.04.3.2 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: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- With the advantages of carbon refractories especially excellent slag resistance and high heat stability, but graphite under high temperature oxidation, in order to improve the oxidation resistance of carbon composite refractory materials, often adding a small amount of antioxidants, to improve the oxidation resistance of carbon composite refractories. Antioxidant additives commonly used in metal powder, silicon powder, magnesium powder, silicon carbide powder and so on.
- Q: Who knows what is the requirement for fireproofing of interior decoration materials ?
- In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.
- Q: Fire rating of decoration materials
- code for fire protection design of buildings
- Q: Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?
- Many enterprises need refractory materials. You can go to Mianyang large private enterprises to askSupermarkets, stations, hotels are required
- Q: What are fireproofing materials?
- Plants often use the fireproof sealing material with steel structures without much modification. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. . Coatings are usually those with fine powder, high density and good sealing. Hardeners mainly depends on specific requirements. .
- Q: What is the material of fire resistant glass reinforced plastics grating?
- What is the material of fire resistant glass reinforced plastics grating?
- 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 is the limit of fireproof rolling shutter?
- Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. Set firewall has difficult sites can use fire shutter fire partition separating, when the back fire surface temperature rise refractory limit determination conditions of fire shutter, the fire resistant limit not less than 3H; when employed does not include back fire surface temperature rise do fireproof limit determination conditions of fireproof rolling curtain, on both sides of the shutter should be set up a separate closed type automatic water spraying system protection, sprinkler system continuation of time should not be less than three hours.
