Q:What are the materials of insulation firebricks?
The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.
Q:What's the A grade fireproofing material?
A grade fireproofing material: 1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire retardant coating; 9. fire-proof sealing material.
Q:Why does refractory need to add coarse firstly and then add fine aggregate?
Adding coarse aggregate is to assure its good combination with fine aggregate. This is just the experience. You don't have to ask.
Q:What refractories have good mechanical property resistance and heat expansion and cold contraction property?
Aluminium oxide ceramics. I would like to know that what kinds of refractory materials can combine together and what kind of masonry way can be used for these materials so as to achieve the perfect combination.
Q:Is aluminium oxide refractory material?
Yes. It has high melting and boiling point, stable chemical property. All refractory material almost contains aluminium oxide. Refractory materials have a large range and need specific requirements. Refractory material is divided into sizing refractory material, shapeless refractory material, ceramic fiber, refractory bricks and castable refractory. It can be subdivided according to temperature rating. Hope it is helpful to you.
Q:whether the aluminum silicate thermal insulation material is fireproof or not?
Yes, it is fireproof. Refractory thermal insulation material mainly refers to the inorganic thermal insulation materials and composite thermal insulation materials. According to the shape it can be divided into: Fibrous finishing, mineral cotton, rock wool, glass wool, aluminum silicate wool, ceramic fiber,ect.. it takes the flint clay clinker as raw material, produced by the fusion of resistance or electric arc furnace and the injection of fiber forming. characteristic: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
Q:What is high alumina refractory?
It refers to inorganic non-metallic material with refractoriness of higher than 1580℃. Refractoriness refers to the celsius temperature that the cone-shaped refractory sample without load can resist, and under which the sample won't soften and melt down. Refractory material appears together with high temperature technology, and roughly dates from the Middle Bronze age. In the Eastern Han Dynasty (AD25~AD220) of China, fireclay refractories has been used as furnace refractories and saggers for making porcelains. In the early 20th century, refractory material develops toward the direction of high purity, high dense and ultra high temperature products, and meanwhile unshaped refractory and refractory fiber with no need of firing at all and with low energy consumption appear.
Q:What is the fire resistance thickness of the thin fire-retardant coatings?
Our thin steelwork fireproof coatings: the fire resistance is 2.5 hours, the thickness is 4.9 mm, the fire resistance is 2.0 hours, the thickness is 3.5 mm, the fire resistance is 1.5 hours, the thickness is 1.75 mm, the fire resistance is 1.0 hours, the thickness is 1.17 mm.
Q:What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?
The refractory material is capable of withstanding high temperature burning, while fireproofing material is to prevent burning. They are different from each other
Q:Which fire-resistant materials have good viscidity?
Viscidity is necessary for gunning mix, repair mix and bordering. It is too broad to which has good viscidity. Both gunning mix and repair mix are powder before adding water. Bordering also has little viscidity before heating. The question shoule be more specific.
