- Q: What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?
- Refractory concrete generally divided into three categories: lightweight concrete (used in insulation); refractory concrete (for refractory temperature requirements are not very high position, and can withstand a certain air scour); heavy refractory concrete (flow with higher requirements for refractory temperature parts, and can withstand a certain intensity). Mainly depends on the design temperature and the use of parts.
- Q: what's the fireproof levels of fireproof and thermal inuslation matertial?
- What are the fireproof levels of fireproof and thermal inuslation matertial on the market? how to divide the fireproof levels of fireproof and thermal insulation material?
- Q: How long is the duration of fire resistance of hollow glass magnesium board
- Glass magnesium board is non-combustible board with excellent fire resistance ability, the continuous burning time of flame is 0, non-combustible at 800℃, no flame at 1200℃, achieving the highest level of fire retardant level A1; Partition System cooperated with high-quality keel can endure fire for more than 3 hours. In the process of combustion, a large amount of heat energy can be absorbed, and the temperature of the surrounding environment will be delayed.
- Q: How to prolong the furnace age of Induction furnace by using fireproof materials?
- magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
- Q: How long is the duration of fire resistance that fireproof door of level B can endure?
- Fireproof doors can be divided into three levels, namely level A,B,C. Fireproof doors of level A can endure fire for 1.50～2.00h while level B for 0.50～1.50h. However, according to national condition, the lowest fire doors fire resistance limit has been specified, namely, level A,1.50h;level B,1.00h; level C, 0.50h.
- Q: What are first rate fire resistant window materials?
- Natural environmental protection, non-poisoned, non-peculiar smell, non-radioactive; non-combustible, fireproofing, moisture-proof, corrosion-resistant; easy construction, lightweight, high strength, www. jsxsmy.
- Q: Who knows the fire endurance of rock wool color plate?
- I'm glad to answer your question and offer you some of my experiences, for reference only. In fire?safety?rules, it can be divided into non-combustible component, hard-combustible component, combustible component according to the combustible degree of building materials. Rock wool board is building board recombinated artificially by fibers processed by coated steels and inorganic minerals like basalt mineral, because steel plate and rock wool which is the main components are non-combustible material, so rock wool board should be considered as non-combustible component. The fire endurance of rock wool board has its own judging criteria. Lose sustaining power, integrity and fire insulation function. Its fire endurance is within 2 hours.
- Q: What is glass furnace used high-grade refractory materials?
- Corundum brick, such as alumina hollow ball brick. In addition, in the key parts of the glass furnace needs to use chromium zirconium corundum material. I'm salesman of zibo lei bao refractories company. The softening temperature of corundum mullite brick is 1500 degrees. So glass melting furnace needs to use refractory materials which high temperature resistance is more than 1600 degrees.
- Q: What refractory materials are used in power plant
- Vacuum mud machine, sintering furnace! And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
