Product Description
Description of alumina cement
Refractory cement is a kind of the refractory material use high quality corundum, alumina magnesia spinel and fused magnetite as raw materials, this refractory mate-
rial is characterized of resistance of high temperature, resistance of erode and
emersion, long life used. What's more, it can be made difference kinds of ladle as your request

- Q:What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
- It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
- Q:Can you tell me the classification of fireproof sealing material.
- Fire blocking is to use fire blocking material as partition between cable threading hole and electric hole. Its role is to prevent the cable itself catacausis or outside naked light make the fire spread to achieve the purpose of protecting the safety of personnel and equipment. The principle of fire-proof sealing is plugging material acting as bloating heat absorption and heat insulation. Fireproof sealing material in current market include: fire-proof sealing plate, foam sealing materials, flame retardant module, flexible organic plugging material, inorganic fire sealant, plugging and fire package, etc. The wide usage of fire-proof sealing material in building construction can ensure the fire flame and high temperature flue gas not to extend another fire partition tendril.
- Q:Is refractory material harmful to human body?
- Part is harmful to human body, mainly refractory raw material, silica powder inhalation can cause lung tuberculosis, siliceous fiber on the human body does have great harm, in fact, like other inorganic fiber in the inhalation of the trachea or lung after the same harm to human
- Q:What's the refractoriness and how to measure the refractoriness?
- Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
- Q:Who knows about the B-level fireproof insulation materials?
- Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof?performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
- Q:What is the fire endurance of ceramsite concrete blocks?
- What is mentioned in fire?safety?rules is that the fire endurance of 240mm thick hollow brick of ceramsite concrete is 2.9h, so 190mm thick hollow brick is 3h. B05 thickness(mm), fire endurance(h). Combustion performance 100 4.0. Non-combustible component 150 6.0200 8.0300 〉8.0B06 100 〉4.0150 〉6.0200 〉8.0300〉8.0: The fire endurance performance of building blocks wall in the table is taken from the Tianjin Construction Standard "light steam pressing aerated?concrete?block" DB / T29-128.
- Q:What effect does aluminium powder play in refractory bricks?
- Aluminum powder is the main temperature resistant material ~ ~ ~ ~!
- Q:What is shapeless refractory with high performance?
- The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
- Q:Who knows about the fire endurance of sintered shaly hollow bricks?
- 1. after roasting at high temperature of more than 1200 degrees, shale burned bricks in construction works can be free from expanding with heat and contracting with cold. 2. masonry walls can be plastered with no needs of any anti-cracking, reinforcement measures, and walls will not bulge and crack, which can reduce the construction cost, as well as are preferred building materials of frame structural engineering. 3.They have good sound insulation and thermal insulation performances, are one of the green building materials that the state currently promotes. 4. They have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance.
- Q:What kinds of refractory will be used in kiln of sintering ceramics?
- If it is ordinary ceramic, you can use ordinary clay bricks and high alumina brick, adding calcium silicate board, the insulating brick and cotton fiber.
