Product Description

  Cenosphere, sometimes called microsphere, is a light weight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas., typically produced as a byproduct of coalcombustion at thermal power plants. The color varies from gray to almost white and their density is about 0.6–0.9 g/cm³, all these property give it a widely application for insulation,refractory,oil drilling,coating,construction use.

Q:What are the types of refractory sealant?
Refractory sealant has low exothermicity and will form a hard corking content during burning, it includes: Liquid polysiloxane has at least two active groups selected from alkoxy, hydroxy and alkenyl; a cross-linking agent, a catalyst, a reinforcing filler and wollastonite. These cured silicone rubber sealant has low heat release and will form a hard coking content structure while buring. Refractory sealant composition can be used in sealing structure to prevent flames, air and other steams passing. 1. In a liquid organic polysiloxane polymeters, each R1 is independently selected from the alkyl, aryl, alkenyl and haloalky which has 1-18 carbon atoms, and each R2 is independently selected from the hydroxy, alkoxy, alkenyl, and X is an integer from about 10 to 1,500. 2. A crosslinking silicone compound having at least 3 silicon-bonded eactive groups. 3. A R2 pressed of silicon bonding capable of promoting component A. 4. Wollastonite and a selective reinforcing filler.
Q:How is refractory material made?
It is made from polyester.
Q:Which refractory is suitable for the tunnel kiln?
Shuttle kiln refractories requires the good thermal shock properties. Because the tunnel kiln is continuous firing furnace, the temperature in the kiln is long time stable and with little fluctuation. The shuttle kiln is intermittent kiln firing. The temperature in the firing kiln is adjusted by the firing curve. It is with a relatively short time and serious fluctuation. The seal and kiln car take use of the heavy corundum brick. If it is continuous kiln, the alumina hollow ball bricks are used in the burning zone. The seal of the burning zone takes use of the kiln car brick and the seal takes use of the heavy corundum brick.
Q:Do you know the refractories?
Acidic material products: these products to quartz (SiO2) as the first phase, SiO2 is an acid oxide, helped named. Brick is representative of the product acid material; semisilica brick, alkali proof brick, acid brick in SiO2 content of 60% to 80%, is a semi acidic material.
Q:What are the grades of refractory exterior wall thermal insulation materials?
Classification of fire rating of extrior thermal insulation materials 1, According to national standard GB8624-97, the combustion performance of building materials are divided into the following grades A level: Incombustible building materials: Materials hardly burn. B1 class: Flame-retardant building materials: Flame-retardant material has good flame resistance. In case of fire in the air or at high temperature, it is difficult to catch fire and the fire will not spread quickly. And when the combustion source is removed, the burning will stop immediately. B2 Class: Combustible building materials: Combustible materials have a certain flame retardancy. In case of fire in the air or at high temperature, it will immediately burst into flames and it is easily to spread fire, such as wooden column, wooden roof truss, wooden beams and wooden stairs, etc. B3 level: Inflammable building materials: It has no flame retardant effect, and it is extremely inflammable, and the risk of fire is high. Classification of exterior wall thermal insulation materials according to fire rating: 1. Thermal insulation materials with A-level combustion performance Rock wool, glass wool, foam glass, foamed ceramic, foam cement, hole-closed perlite, etc. 2, Thermal insulation materials with B1-level combustion performance: Extruded polystyrene board (XPS) after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polystyrene granule, and etc. 3. Thermal insulation materials with B2-level combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:What are the new refractories?
Most are ordinary refractories.
Q:What's the commonly used refractory material for ladle?
1. According to the refractoriness, it can be classified as follows: common refractory: 1580℃ ~ 1770℃; high grade refractory: 1770℃ ~ 2000℃; superrefractory: 2000 ℃; 2. According to the shape and demension of the product, it can be classified as follows: standard form : 230mm×113mm ×65mm of no more than four measuring scale, (demension ratio) Max: Min
Q:Does anyone know about the A-level fireproof materials?
rock wool external wall composite board, A1-level fire rock wool board, hidden slit rock wool board ¥ 30, A1-level fireproof mineral wool sound-absorbing board. What about the sound-absorbing sheet? glass fiber acoustic board engineering of the TV backdrop ¥ 85, A1-level fireproofing and thermal insulation rock wool board is hydrophobic thermal insulation, external wall thermal insulation materials ¥ 200, high temperature resistant calcium silicate board, LCFC/calcium silicate board is A1-level fireproof materials with high-quality and low-price ¥ 75, the prices above are from the internet for reference only, and the purchase prices vary according to the market.
Q:The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
Yes. After moulding by casting in the firing of 1450 ° degrees.
Q:How long is the fire endurance of Grade A fire resisting shutter
Based on national standards GB 14102-2005 specifications. It is specified in GB 14102-2005 provides that: The fire resisting shutter whose fire endurance is not less than 3h is AAA fire resisting shutter when the unexposed surface temperature rise is used as judging condition. Therefore, it is required that the fire endurance of Grade A fire resisting shutter is 3h.
