Q:What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?
Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)
Q:How many kinds of refractory materials are there in the EI?
I suggest that you contribute articles to foreign SCI journals for the odds are better, and generally the articles that fill the bill will not be rejected. The traditional refractory materials can contribute to EI journal. If being rejected by EI journal, you can also contribute to Russia's journal Industrial Ceramics and Refractories. I didn't contribute to the Journal of Wuhan University of Science and Technology, the receiving cycle is almost 3 to 4 months. Though the impact factor is low, domestic EI journal is not so good, it is still SCI journal. This is my own experience, please take my advice. The best journals are the Journal of the American Ceramic Society and the Journal of the European Ceramic Society, I heard that they are not bad. But the best domestic EI refractory material journal is the Journal of The Chinese Ceramic Society. It is very long, but if it belongs to your university, it is another pair of shoes. Journals now all want to have materials about functional ceramics, and they don't want Chinese articles, if your English is not well enough, you can choose Ceramics International and Japan Ceramics but they have strict manuscripts reviewing standards.
Q:What are the differences between intensive refractory busway and other busways?
Compact busway is named according to its structure, and fire-resistant busway is named after its uses. Compact busway especially refers to busway which is closely laminated between phases and between phase and shell, and use thin insulating material to achieve the insulation result. Suitable for power supply system of alternating current three-phase four-wire, three-phase five-wire system, frequency of 50 ~ 60Hz, rated voltage up to 690V, rated operational current of 250 ~ 5000A, as auxiliary equipment for mining, enterprises and high-rise buildings, and especially suitable for the transformation of workshop and old enterprises. Fire-resistant busway is composed of shell coated with fire retardant paint, bus line wrapped with fire-resistant mica tape and bracket made by refractory insulating material. Bracket has a plurality of grooves where inbedding the bus line and fixed it. There is a busway connecting box at one end of the busway and there is a bus line splitter box in the busway. Fire-resistant busway has excellent insulation properties, which can not only be used continuously in a normal environment, but also can be used in the fire environment continuously for more than one hour, suitable for high-rise buildings and important facilities.
Q:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
Common red brick and refractory brick.
Q:what textures of furnace refractories are good?
First, it depends on the kiln. If it is the cubic kiln, the top and the wall portion should use alumina hollow ball bricks. The bent seal and kiln car use heavy corundum bricks. If it is the consecutive kiln, the burning zone shall all use the alumina hollow ball bricks, and both the burning zone bent seal and the brick kiln car bent seal use the heavy corundum bricks. Ifit is the pit furnace, furnace walls and roof use the alumina hollow ball bricks, and the bottom of the furnace use heavy corundum bricks.
Q:Does the external wall thermal insulation materials level b1 need the fire barrier zone?
First, it is prohibited that the thermal insulation material of level B2 and below combustion performance is used in the thermal insulation project of any civil building wall, and the thermal insulation material of below level A combustion performance is used in the thermal insulation project of curtain wall civil builduing that the height is equal and greater than 24m, of non-curtain wall residential building that the height is equal and greater than 100m and of other non-curtain wall civil builduing that the height is is equal and greater than 50m. Civil builduing wall thermal insulation project must strictly enforce the "civil builduing external wall thermal insulation systems and external wall decoration fireproofing interim provisions" (referred to as "fireproofing interim provisions").
Q:What is the importance of silicon powder in refractory processing?
it can certainly improve the fire resistance
Q:What is the principal part of silicious refractory material
lightweight silica bricks, product with fused quartz, the silicon dioxide content is generally greater than 93%, including silica brick silicious refractory SiO2 as a main component of refractory products
Q:Does the aluminum silicate thermal insulation material fireproof?
How does its fireproof performance? this is the material that the decoration master worker recommands to me, how do you think of it?
Q:How do refractory materials apply into pyrophyllite?
Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
