Q:What refractory material lead smelting furnace needs?
Q:Why can aluminium hydroxide not be used to make refractory material?
Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
Q:How long is the fire-resistant time of fireproof wooden door?
The fire-resistant time of fireproof wooden door is about 1 hour. Fireproof wooden door refers to the door whose door frames, skeleton of the door leaf, door panels are made of timber or timber work and fire endurance reaches the provisions of "GB50045-95 design of tall buildings for fire protection". Fireproof door is one of devices for fire prevention and separation of the building, generally used on the firewall, entrance and exit between stairs pipe shaft opening, which plays an important role in the reduction of fire losses.
Q:What are the requirements of refractory temperature of refractory brick?
Refractoriness can reach 1690 degree, but the highest operating temperature is 1350 degree. If the temperature goes higher, operation life will be greatly shortened.
Q:What is the importance of silicon powder in refractory processing?
it can certainly improve the fire resistance
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:Which company needs the new refractories?
The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.
Q:What are the requirements of the performances of brasque refractory?
Physical properties of refractories include structural property, thermal property, mechanical property, usability and operation property. Structural properties of refractories include porosity, bulk density, water absorption, air permeability, pore size distribution,etc.. Refractory thermal properties include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, thermal emissivity. Mechanical properties of refractories include compression strength, tensile strength, breaking strength, torsional strength, shear strength, impact strength, abrasion resistance, creep property, bonding strength, elasticity modulus. usabilities of refractories include refractoriness, refractoriness under load, reheating linear change, thermal shock resistance, slag resistance, acid resistance, alkali resistance, water resistance, corrosion resistance to CO, conductivity, oxidation resistance, etc.. Operation properties of refractory include consistence, slump, fluidity, plasticity, cohesiveness, resilience, coagulability and hardenability,etc. I hope you can solve the problem with my answer.
Q:Which brand of AAA refractory is good?
The most famous is fire dragon. The Morgan and Lu Yang are all very good at making common thermal insulation material. The price is not very expensive, and the quality is comparatively good. The refractories are capable of good thermal shock resistance ability and chemical errosion resistance ability It is a non-metal material with a low heat conductivity coefficient and expansion coefficient. It requires high temperature in nature. The production base of silicious thermal insulation board is difficult to transport raw material. The silicious thermal insulation board is a high temperature thermal insulation material with the raw material of non-porous refractory aggregate and porous refractory aggregate, organic fiber and inorganic fiber.
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
