Q:What are the specifications of fire resistant bag?
Mesh number, namely hole number, refers to the hold number in each square inch. 5o mesh refers to 50 holes in each square inch and 500 mesh 500 holes. The larger the mesh number is, the more the holes are. The larger the mesh number is, the smaller the hole aperture is. Generally speaking, mesh number× aperture (microns) = 15000. For example, the aperture of a sieve of 400 mesh is about 38 microns; the aperture of a sieve of 500 mesh is about 30 microns.
Q:What are the advantages of refractory material?
Jingute WHL type, GDS type
Q:What is the material composition of the new fire-resistant coating?
New fire?retardant?coating materials are produced by non-toxic expanding materials and special process, with no pollution. Use natural bite when installing, without using the formaldehyde and other toxic glue. It consists of a variety of organic matters, so it adapts to the natural environment, with long time of fire-resistant; The fire-resistant time for new fire retardant module is up to 4 hours or more, three hours more than the standard prescribed by the state. It is composed by the specially formulated materials, with no flying smoke, good heat insulation effect, fast heat dissipation, scientific and rational design, easy using and no falling off and long period of effective.
Q:What is acid refractory material?
In fact, with the content of zirconia refractory multiple theory should also be acid refractory
Q:Who knows the fire resistant level of the rock wool color plate?
The rock wool color steel rock wool board is used in a area of high ??fire safety requirements. According to "interior decoration of buildings for fire protection design", the color steel rock wool board belongd to level A. Its life is more than 15 years and still can be used when the temperature is up to about 700 ℃, with maximum fireproofing hour of six hours. And the rock wool color plate is a environmentally friendly material, the preferred material in the construction industry .
Q:What are the models of refractory cables?
NH is the firat letter of "refractory" in Chinese phonetic alphabet; It is V, not W. PVC insulation and sheath; K in KVV represents the control cable. 5 * 10 represents the cable is made up of 5 core cables whose nominal cross section is 10 square milimeter.
Q:what's the materials of fireproof?housing?
there are mainly several fireproofing levels, it is divided into flame retardant and non-combustible! at present t the main fireproofing materials on the market are made from rock wool board! it is incombustible?material, of course, the price is relatively high. Other common materials are fire?retardant foam.
Q:How to classify fire resistance rating of brick-concrete structure?
In order to ensure the safety of the building, the fire protection measures must be taken to make it have a certain degree of fire resistance, even if there is a fire, it will not cause too much damage. According to the national conditions of our country, and in the light of other countries standards, < high-rise civil building fire protection design specification > defines fireproof rank of high-rise civil buildings into level one and two; < code for fire protection design of buildings > divides the rank into level one, two, three, four, level one is the highest level, level four is the lowest. Besides that the minimum fire resistance of the building component is specified, buildings of fire resistance rating also specified requirements for combustion performance. Because the component with the same fire resistance limit is different, it is different in the fire.According to our country national standard < building design fire protection code >, the fire resistance rating of the building is divided into four levels. The fire resistance of a building is determined by the combustion performance and fire resistance of building components (such as beams, columns, floors, walls, etc.). Generally speaking, the fire resistance building of level one is a mixed structure of reinforced concrete structure or a mixture of brick wall and steel concrete structure; the fire resistance building of level two is a mixed structure of steel truss structure, reinforced concrete column and brick wall; the fire resistance building of level three is brick-wood structure made of wood roof and brick wall; the fire resistance building of level four is combustible structure which is composed of wood roof and non-combustible wall.
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:Does the refractory material used in steelmaking all refer to refractory brick?
The refractory material used in steel making doesn't all refer to refractory brick, but also includes refractory castable. The foaming?agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.
