- Q: which kind of material is chosen for fireproofing window?
- (1) window frame uses steel frame or wooden frame with certain strength that can safeguard the integrity and stability of the components. (2) steel frame and mound layer can choose galvanized?steel?sheet or stainless steel plate. Its selection criteria conform to the article 5.1 in GB12955 Steel Fireproof Door General Technical Condition. (3) the selection criteria of wooden frame and mound layer should conform to the article 5.1 in GB12955 Wooden Fireproof Door General Technical Condition. (4) the inside filler material of steel, wood frame should use incombustible material. (5) fire-resistant glass can choose test approved products without affecting the fire resistance of fireproofing windows . Light transmittance of glass should not be less than 75% of same layers commom sheet glass. (6) the sealing material between the frame and the fire-resistant glass should use flame retardant materials, it can play a role of fireproofing and smoke insulation in the fire.
- Q: For refractory, what is critical particle size? Thank you.
- For example, in refractory technology, if there is an express of equal to or lower than 0.008mm, 0.008 refers to critical particle size. The main criterion for judging performance of three major continuous casting is the major three normal temperature indexes (compressive strength and anti bending strength at normal temperature, apparent porosity and bulk density). Does this criterion have any defect? How to do multiple test if high-temperature index introduced? Carbon bond is one of the three major castings. How does it form? What do you think of it? Hope someone explains it for me. Thanks a lot!
- Q: how about the performance of aluminum silicate fire proof thermal insulation?
- aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing?agent, molding by high temperature and high press. MDF(medium density fibre board) structure is more even than natural wood. it avoids rot, moth-eaten and other problems, while medium density fiber board has small expansion and contraction, which is easy to be processed. Since the surface of medium density fibre board is smooth, the board is easy to paste a variety of finishings, which makes furniture more beautiful. A variety of decorative wood-based panel is to embellish their homes.
- Q: What effect does aluminium powder play in refractory bricks?
- Aluminum powder can increase the high melting point of refractory refractory, while increasing material density, hardness and other changes in physical properties of aluminum powder in the application of unshaped refractories in the gas can be discharged in the material, prevent the refractory sudden warming occurred during the burst.
- Q: How to make fire resistant materials for building stoves
- Grand Theft Auto Vice City plus life code is what?
- Q: What's the material of electrical fire prevention board?
- Electrical fire prevention board uses the material of inorganic binders, which mainly includes water glass, gypsum, phosphate, and cement; refractory mineral fillers: alumina, asbestos powder, calcium carbonate, perlite, cornstarch and etc.; electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface. Hope my answer is helpful for you.
- Q: What can red stone refractory do?
- In severe cases, the resistance to high temperature without softening down the Celsius temperature. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output. Chinese use less impurity clay in more than 4000 years ago, firing pottery, and have been able to cast bronze. In the Eastern Han Dynasty (AD 25 ~ 220) have been used to make clay refractory kiln firing porcelain material and sagger. At the beginning of twentieth Century, the development of refractories to high purity, high density and ultra high temperature products, while developing completely without firing, small consumption of unshaped refractory materials and high refractory fiber (160 for industrial furnace refractories above 0 DEG C). The former, such as alumina refractory concrete, is often used in large chemical plants, ammonia synthesis plant, two - stage reformer furnace wall, the effect is good. Since 50s, the rapid development of atomic energy and space technology, the development of new energy technology, requires the use of special refractory material of high temperature resistance, corrosion resistance, thermal shock resistance, erosion has excellent properties, such as melting point above 2000 DEG C, oxide refractory compounds and high temperature composite refractory materials.
- Q: What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
- 04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
- Q: What is the limit of fireproof rolling shutter?
- Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. Set firewall has difficult sites can use fire shutter fire partition separating, when the back fire surface temperature rise refractory limit determination conditions of fire shutter, the fire resistant limit not less than 3H; when employed does not include back fire surface temperature rise do fireproof limit determination conditions of fireproof rolling curtain, on both sides of the shutter should be set up a separate closed type automatic water spraying system protection, sprinkler system continuation of time should not be less than three hours.
