Q: What is the difference in the nature between the refractory material and thermal?insulation?material: thermal?insulation?material is used to thermal insulation and the transfer of heat insulation. refractory material is defined as greater than 1580 ° non-metallic materials, such as calcium silicate board. its using temperature can reach to 1100 degrees, and some can also be used at high temperatures, and all high-temperature industrial can't be oprated without it, and the using temperature of polycrystalline alumina fibers can reach to 1800 degrees

Q: What's the refractory material?: Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica?brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.

Q: Is there any difference between insulating bricks and refractory bricks? Are there any professional refractories factories that are reliable in the quality and quality of these irritated materials?: High alumina brick, clay brick, brick and other high-quality refractory products, widely used in metallurgy, building materials (cement and glass), non-ferrous metal smelting, petroleum, chemical, electric power, machinery manufacturing and other industries.

Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name, hope you adopt.

Q: what kind of fireproof materials is used for high rise buildings?: First, fire resistance steel door: in the general real estate, developer uses more of fire resistance steel door. The mid-low-end doors are the earliest products and mostly widely used with longer servce time. The disadvantages are corrosions, thus it will rust, fade after being used for a while, and will affect the overall appearance. Styling lines are hard, not matching well with modern home decorative styles. Second, the stainless steel fire doors: anti-theft performance ,durable, stronger security. Compared to the general iron or mixed iron and steel security doors, stainless steel doors never rust and most importantly its uniqueness in addition to lasting bright color. Disadvantages: Stainless steel security doors are mostly silver, giving us dull feelings by seeing its appearance and color, lack of coordination. Third, glass fire door: high quality fire glass doors. recent years have seen wide application in office buildings and some high end public place, less in individual users. Compared to the current categories of timber, fire glass door is not only simple and luxury and durable.

Q: What is the type of heat resistance property of high temperature electric furnace ?: According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃

Q: Detailed description of magnesia dolomite refractory material?: The CaO of magnesia dolomite refractory is beneficial to the purification of molten steel. In the aspect of smelting clean steel, magnesia dolomite refractory also has good dephosphorization and desulfurization effect.

Q: Who knows the external wall thermal insulation materials fire rating requirements?: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the unit price is very expensive. Insulation materials in the domestic market have some disadvantages, it is better to considere the materials within the acceptable range in the building needs.

Q: How many levels are there in the classification of PP fireproof materials?: The level of fireproof materials: A-level: Non-combustible building materials have rare chance to burn. A1-level: Non-combustible materials, no open fire A2-level: Non-combustible materials, smoke should be tested and qualified. B1-level: Fire-retardant building materials: Fire-retardant materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. 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. B3-level: Inflammable building materials are highly flammable with no flame retardant ability, fire risk is high.
