Q: What is the role of adding chromium oxide green in unshaped refractory materials: Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.

Q: Does anyone know the refractory temperature of fire-resistant glass?: Ordinary glass will be completely liquefied in the furnace of about 1100 degrees for half an hour and will not deform below 600 degrees. toughened glass fire-resistant glass is the product of ordinary glass after being processed Glass will mainly burst after encountering fire. When unevenly heated or encountering sudden drastic changes in temperature, ordinary glass will burst if the sharp temperature difference is over 70-120 degrees and toughened glass will burst at 200 degrees. It is not yet clear of the bursting temperature for the refractory glass. (I hope this answer can help you!) Hope you adopt !)

Q: What are the requirements of the performances of brasque refractory?: Physical properties of refractory include structural properties, thermal properties, mechanical properties, usability and operation property. The selection of the brasque refractory must have the following characteristics: 1. properties of not distortion and not melting at sufficient temperatures 2. have the necessary structural strength at high temperatures and does not soften and deform 3. must keep stable volume at high temperatures and will notcrack caused by expansion and contraction 4. will not rapture and flake when temperature is drasticly changed or heated unevenly 5. resistant to chemical erosion of metallic solution, slag and furnace gas, etc.

Q: Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.: Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.

Q: What's the refractory material in common use currently?: According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).

Q: Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?: 1.The insulation materials with A-level combustion performance: EPS Hairong module, rock wool, glass wool, foam glass, ceramic foam, foam cement, closed-cell perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. The insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene boards(XPS), Polyurethane(PU), Polyethylene(PE), etc. See the 2009 measures of building technology. The A-level insulation material is only fireproof, the insulation performance of it is worse than that of organic XPS \\\\ EPS material. Currently I think that the best insulation material should be Hairong EPS module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range.

Q: What kind of refractories do the anode baking furnace use?: Usually the clay refractory bricks will be able to meet the requirements

Q: It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?: The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic

Q: who knows the technology of fireproofing material?: First: Firstly, you should produce the recipe and prepare the raw materials, for example, if you prepare to produce 1 ton, you should compute the recipe sheet of 1 ton producing; check whether the raw materials are complete; second: make the color and filler thick liquid; add water in order and proper auxiliary in a low speed, then put color and filler (generally we should firstly add something with large oil absorption), wash the meachine after putting the powder. Then seperate them for about 20 miutes in a high speed, until the fineness is qualified; of course, if you need sander, i think you only need sino-soviet differential powder material and non-obvious particles. Third: Paint mixing period: after making the color and filler thick liquid, reduce the roll speed into about 600 roll per minute, add emulsion and proper auxiliary, finally adjust PH and viscosity. Liquid solvent paint, pigment paste: Resin,solvent and pigment ---〉pre mixing---〉stick---〉grinding--〉stick--〉packaging, highlight varnish: Resin, solvent ----〉mixing ----〉stick ----〉packaging, sub-gloss varnish: Resin, solvent----〉mixing----〉matting agent,stick----〉packaging, colored?paint: The primary colorant----〉Color matching by auxiliary color paste----〉stick----〉packaging, aluminum?paint: Aluminite powder soaking----〉resin----〉colour modulation, lustre adjusting----〉stick----〉packaging, powder coat: Resin,filler,pigment,auxiliary---〉mixing---〉extrusion---〉cooling---〉smashing---〉sieving---〉 packaging.

Q: Who knows how many poured refactory material are there?: Pouring refractory material can be classified into the followings according to the body density: Heavy (> 2.0g\cm3), medium heavy (1.0-2.0g\cm3), light (0.4-1.0g\cm3); by binding agent: Combination of hydration, chemical binding, condensation, hydration and condensation: Clay, high alumina, silica, magnesia, alumina magnesia, magnesium and chromium, magnesium zirconium, silicon carbide etc.. Clay brick, high alumina brick, bead brick, silica brick, light mullite, alumina hollow spherical brick, oxidation zirconium hollow spherical brick, corundum brick, magnesia brick, magnesia brick, magnesia alumina spinel brick, magnesia chrome brick and so on
