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:Which kind of furnace hearth refractory is better?
Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
Q:what is best for making refractory insulation for Blast furnace, hot stove.
clay brick, insulating brick can endure relatively high temperature and last longer than the general fireproof fiber.
Q:What are the specifications of fireclay bricks?
Specifications of fireclay bricks are shown in the figure;
Q:How to deiron refractory?
Deironing refractory can take physical methods into consideration, such as magnetic separation, reselection, etc. And it can also take chemical methods, such as flotation.
Q:How is the division of the fire resistant level of the rock wool board?
It's like this: China's national standard GB8624-97 divides the combustion performance of building materials into the following grades. Level A: non-flammable building materials. Level B1: flame-retardant building materials. Level B2: combustible building materials. Level B3 flammable building materials. section II Combustion performance and fire endurance of building components. First, The combustion performance of buildings of building components. The building is composed of components, such as foundation, walls, lubrication columns, beams, plates, roofs and stairs, ect. Building components are constituted by the building materials, whose combustion performance depends on the combustion properties of the used construction materials. Section One Combustion performance of building components. The building components are divided into three categories according to their combustion properties. First, non-combustible component: the component made by incombustible materials. The incombustible material refers to that when meeting the Oxygen in the air, it will not burn.
Q:What's the fire resistance rating of the exterior fire retardant coating?
First of all, fire retardant coating has no class distinctions. Buildings fire resistance rating is generally classified as follows: I grade fire resistance, II grade fire resistance, III grade fire resistance, IIII grade fire resistance. Buildings with I grade and II grade fire resistance are much common. According to the coating thickness, exterior fire-resistant coating for steel structure can be classified as follows: 1. Exterior thin fire-resistant coating for steel structure, 2. Exterior ultra-thin fire-resistant coating for steel structure, 3. Exterior thick fire-resistant coating for steel structure.
Q:Can anyone tell me what material the first rate fire resistant door is?
Material of Class A fire doors mainly are steel, wood, steel and wood, and other materials. Fire door is one of the measures of the building fire separation, usually used on the firewall, entrance and exit of staircase or tube well openings, which is required to hane the abilities of smoke insulation and fire insulation. Fire door plays an important role in prevention of the spread of smoke and fire and the reduction of fire loss. Therefore, we must have strict requirements. Fire doors are divided into class A, class B and class C, whose properties of fire-resistant thermal insulation and fire-resistant integrity should be no less than the following values: Class A should be1.50h; class B should be1.0h; Class C should be 0.5h. - stipulations in article 4.5.1.2 in "The New Standard of Fire Doors" GB12955-2008. I hope my answer can help you. Thank you.
Q:How is the performance of refractory materials?
It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
Q:What are the additives and recipes of refractory?
Water reducing agent is to evidently reduce mixing water content while keep the slamp value of refractory castable almost invariant, also known as fluid loss agent. Water reducing agent itself cannot have chemical reaction with material component or compose new chemical compound, but it just seemingly has physical and chemical reactions. The binding agent of refractory castable is calcium aluminate cement combined with clay and oxide micro powder. In commonly used water reducing agents, the inorganic includes sodium pyrophosphate (Na4P2O7), sodium tripolyphosphate (Na5P3O10), sodium hexametaphosphate [(NaPO3) 6], super sodium polyphosphate (Na2P4O11), sodium silicate (Na2O · nSiO2 · mH2O), and so on; the organic includes lignosulphonate water reducer (sodium lignosulphonate, calcium lignosulphonate); naphthalene water reducer (naphthalene sulfonate or naphthalene homologues with formaldehyde condensate): water soluble resin water reducing agent (sulfonated melamine formaldehyde resin, abbreviated as composite of melamine water reducer).
