- Q:The shape and size of general used refractory brick
- According to the national standard, the outline dimension of mechanism red brick is: length is 240mm, width is 115mm and thickness is 53mm. That is: 240mm * 115mm * 53mm. The shape and size of the ordinary refractory bricks are: Length is 230mm, width is 114mm and thickness is 65mm, that is: 230mm * 114mm * 65mm. The shape and size of special refractory bricks are: 345mm*328mm*97mm.
- Q:What type of refractory brick won't deform or crackbe for a long time in the temprature of about 1600 degrees?
- 1. , mullite poly light ball brick type, andalusite brick type: MJ-1600 MJ-1700 the temperature is higher than 1600 C. 3, the refractory bricks that won't deform or crack in the 1600 degrees Celsius for a long time includs the following several commonly used bricks: GMZ-80 GMZ-75 the temperature is higher than 1650 DEG C, 2, corundum mullite brick type
- Q:What's the difference between singled-sided conductive aluminum tape and double-sided conductive aluminum tape?
- The differences between single-sided aluminum tape and double-sided aluminum tap: Single-sided aluminum tape only has one side of conductive aluminum foil while the double-sided aluminum tape has two sides. Single-sided conductive aluminum tape. Bridge erecting machine is composed of single main-beam, landing leg, hanging beam trolley, ambulatory and transverse gadget, electronic control system, etc. Double-sided conductive aluminum tape. Main beams often adopt triangle truss style, Bailey truss style or box structure.
- Q:What defects may causes through the aluminum foil roll?
- All the rolls can cause surface damage factors, can be formed on the aluminum foil rolling harm. Because aluminum foil rolling roll surface finish high, slight gloss surface unevenness will affect its status. Periodically clean mill, mill kept clean, to ensure the normal operation of roll clearance, roll change periodically, reasonable grinding, it is to ensure a uniform surface substantially aluminum foil rolling conditions.
- Q:What's the function of aluminium dihydrogen phosphate on the refractories?
- Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace
- Q:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
- Add some hair and slags, or it will crack before calcination.
- Q:Who is going to handle the comonent joint of GRC in the exterior wall?
- Both of them should be tested. The installation process will handle it in surface flat, the rest of the process will continue.
- Q:Is there aluminum coil of 44mm wide and 0.40mm thick?
- The common width of aluminum coil is 1000mm or 1220mm. If you want 0.4mm*1000MM aluminum coil, you can strip 0.4mm*1000MM aluminum coil.
- Q:Production and process of glass fiber
- The process of glass fiber generally includes: Purchase raw materials, mix according to the formula, and then transferred to the glass furnace for melting and refining, after operation channel flow to the bushing, the sizing agent after coating by wire drawing machine traction, then form the original cake, and then flow to the rear section reprocessing procedures (usually a short cut, winding, weaving, puffing and twisting) or sell (direct yarn)
- Q:What's the material of aluminum foil roller
- The aluminum foil roller is the interior document. The roller plant and rolling mill take the advantages of the pressure of temperature change.
