Q:The fire prevention board line is made of what material?
Crural line: wooden, in the market, there are sjoiner woodblock, peach wood and artificial engraving. The second classification is stone and the most used one is the marble graved or ceramics well-made one is taken as the first choise. Its price is a little bit expensive than the wooden one, but also a suitable choise. Condole supports: It has various category. The general furniture choose plaster and anti-firing plate and the other also have a choice of steel. You can make a suitable choice according to the need. If it is contracting project, it depends on your project specific plan and funds plan. In a word, beauty and harmony should be given priority since it is the source of design.
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: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:Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?
Directly using silicon molybdenum kiln, the temperature is better. Now using the electricity is cheaper than the price of other fuels.
Q:Why should graphitic refractory materials be used now that graphite can burn?
C is inactive in nature. Carbon will not burn unless the temperature is about 2000℃, so it can't be lit generally. Coal can be lit because it contains other combustible substance which ignite carbon indirectly. While graphite, carbon black, is more pure and dense than coal., so it is hard to oxidize.Their molecular structures are also different, just like diamond is harder than graphite.
Q:What's the definition of fire endurance of the fire-resistant coating for steel structure?
1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.
Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
Q:Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?
Which standard? Please be more specific
Q:Is the linear change on reheating the same as heating permanent linear change of refractory material?
“+”represents expansion. the afterexpansion and aftercontraction after cooled to be at room temperature. The change may significantly damage the masonry of thermal kiln. There are regulations on the linear change on reheating of common refractory material in the national standard. Some physical chemical changes may continue. It is defined as the change from being heated to the specified temperature of refractory material sample. Heat preserving for a while till afte cooling to be at room temperature, then the residual will expand or contract in its length, heat preservation for a while, organization vitrification, the irreversible changes of its length refers to heating the firing refractory to be at high temperature, so as to make the volume of refractory materials expand or contract, due to the influence of uneven temperature or lack of time, otherwise it will cause the deformation of the refractory ball and make this indicator within standard even reach smaller value, so firing control must be strengthened in product production. But it is should not be too high. For refractory materials with same chemical composition, the linear change on reheating is produced in the heating process. Properly increasing sintering temperature and prolonging the holding time is an effective process measures, make its firing inadequate. When subjected to high temperature, it can reduce the thermal shock resistance. Minus sign "-" represents contraction. The permanent line rate refers to heating the fire refractory ball to the specified temperature. Linear change on reheating, also known as residual linear change, is an important indicator to assess the quality of refractory in the long time use. To control the permanent line rate within the standard or reach the minimum value.
Q:How is the development of Xinmi refractories industry? What's its advantages and disadvantages?
I don't know how it has developed. Its advantage is the coal industry. You have to know the generating capacity in Xinmi thermal power plant first, and then you will know their coal cinder yield, after all, this is the raw material. Xinmi is not far away from Zhengzhou. The real estate in Zhengzhou is still good. I'm not sure about the others.
