Q:what is the specs of thermal insulation refractory slab ?
According to different requirements of each project to select the fire board. fireproof panel should have product qualification certificate. Specifications shall comply with the requirements of design drawings and inspection reports from the National Fireproofing Protection Building Materials Inspection Center. General specifications are as follows: Length: it is determined according to the project width: 1200mm, 900mm; thickness: 9.5mm, 12mm, 15mm, 18mm, 25mm. Commonly used is 12mm.

Q:What's the frequently used refractory material?
Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded magnesia-chrome bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory castables, etc.
Q:As for fireproofing material rock wool and glass wool, which one is better?
Rock wool board and glass wool board are a kind of new construction thermal insulation material, it's widely applied in construction and has replaced traditional thermal insulation material to some degree. With the gradually deepening study of rock wool board, glass wool board, we can find that these insulation materials have advantages in many aspects but there are also many deficiencies, particularly there exists a lot of controversy about the impact on the human body. The production process of rock wool board and glass wool board usually includes: after melting in high temperature of rock or glass, inorganic fiber is produced by high-speed centrifugation equipment, and at the same time add binder,dust laying oil,silicone oil at certain proportion, then produce sheet material according to different requirements. It has good thermal insulation properties, mechanical property, sound absorption characteristics, belong to incombustible material and is cheap. In general, insulation, security and economy should not be contradictory, three aspects should be taken into account, balanced chosen and developed. Rock wool board and glass wool board and other such materials should be properly selected and applied to the appropriate structure, so that the choice of material will play their strengths and avoid their weaknesses.
Q:Does anyone know the characteristics of refractory for glass kiln?
Quartzitic sandstone. Also known as quartzitic sandstone or white gravel. Which is a kind of natural refractory and quartz sandstone bonded by the kaolinite. Who appearance is better to be steel-grey, dense and hard, free of impurities and stripes. Its main crystalline phase is mainly quartz and kaolinite. Which has obvious stratified structure and anisotropism. The refractoriness fluctuation is between 1650~1730 ℃. The expansibility of quartzitic sandstone is different from that of silica brick, who has maximum coefficient of thermal expansion under temperatures of 700 ~ 800 ℃, and it is most likely to burst at this time. The load softening temperature and the compression strength of calcined quartzitic sandstone have been improved significantly, with small residual expansion, stable volume, better thermal shock resistance, so it is generally to use calcinated quartzitic sandstone as refractories. which has been widely used as sidewall blocks on the small and medium sized furnaces.
Q:Where is the sizing nozzle for refractories? Just enter the line, master into!
This is the use of steel tapping water procedures inside!!
Q:What are the applications of refractory in petroleum?
It can be used in chemical filler. For general process, some insulation parts also need to use refractory.
Q:What are the characteristics of clay refractory materials?
Clay refractory has excellent performance in anti fatigue. The fatigue strength of the general metal is 50% ~ 40 of the tensile strength, and some composite materials can be as high as 70 ~ 80%. The fatigue fracture of the composite is from the matrix, which is gradually extended to the interface between the fiber and the matrix. Therefore, the composite material has omen before destruction, and it can be checked and remedied. Fiber composite material also has good performance in anti vibration fatigue. The fatigue life of The helicopter rotor made of composite material is longer that made of metal. I hope my answer will help you!
Q:which is better as household fireproof material ?
If it is from the perspective of fire rating inorganic active insulation material for wall thermal, cement foam insulation board, glass beads of insulation movitrified micro bead thermal insulation mortar, rock wool board, glass wool board, ect.. thermal insulation material are Class A fireproofing, polyphenyl board, extruded sheet, phenolic foam board, Polyurethane board, ect..belong to B1 level fireproofing, if it is used for external wall thermal insulation in decorative board, then rock wool board is more often used.
Q:Can anyone tell me which materials are fire-proof high temperature resistant material?
Fireproof high temperature resistant material is the synthetic material with fireproofing properties, or the material itself is high temperature resistant, heat-resistant, flame-retardant material. Fireproof materials are mainly used for construction with a variety of forms, which plays an absolute role in modern fire protection. The commonly used fireproof materials including fireproof panels, fire doors, fireproof glass, fire retardant coating and fireproof bag, etc.
Q:How to hang the suspended brick in the refractory masonry?
First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.
