- Q:Is liquid phosphoric acid two aluminum hydrogen flammable?
- Two aluminum liquid hydrogen phosphate using spray paint, cement, refractory castable and binder for foundry industry, mainly used in refractory industry corundum, chromium corundum nozzle coal water slurry gasifier with chromium aluminum zirconium corundum brick production.
- Q:Application of electric high temperature regulating valve?
- Acid refractory with silicon oxide (SiO2) as the main ingredient, commonly used are silica brick and clay. Brick is siliceous products containing more than 93% SiO2, the use of raw materials with silica, silica and other waste. The silica acid slag erosion ability is strong, but vulnerable to the erosion of basic slag, its softening temperature is very high, close to the fire, the volume does not shrink after repeated burning, or even a slight swelling, but the thermal shock stability. The brick is mainly used for thermal equipment of coke oven, glass furnace, furnace and other acidic silica brick, according to the physicochemical indexes and SiO2 content can be divided into several levels, mainly used in glass furnace and coke oven silica brick for two categories. Clay brick with refractory clay or bauxite clinker as main raw material, containing 30% to 46% of alumina, refractory degrees 1580 to 1770 DEG C, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used in refractory clay brick clay as main raw material is called common clay brick that made pyrojewel clinker as the main raw material, the porosity in the clay brick below 17% is called low porosity clay brick. Two kinds of clay bricks are divided into several grades according to the physical and chemical indexes. The price difference between the ordinary clay bricks and the low porosity clay bricks is great.
- Q:Which is good, glazed brick and whole cast glazed brick?
- Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.
- Q:What is the blast furnace ceramic cup called by the refractory factory?
- The refractory bricks, which are suitable for blast furnace conditions, are vitrified by high temperature sintering. They are like a huge cup, so they are called ceramic cups. The name was taken by the French, and the technology was handed down from france!
- Q:What's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
- Fused zirconia corundum brick has a strong resistance to glass liquid corrosion!It is better to fuse the furnace with fused zirconia corundum bricks.Fused zirconia corundum brick, regardless of the size of the furnace, the use of small hundreds of kilograms can be used, depending on the design of the kiln!
- Q:How much is a refractory brick?
- This question is too general, refractory bricks according to the use of the environment and industry, there are a variety of materials, a variety of specifications, prices vary greatly.
- Q:What kind of refractory material will be used in the glass kiln?
- It has the best resistance to high temperature E glass corrosion, its erosion basically does not cause pollution to the glass liquid, so it has become the first choice of E glass unit refractory bricks.Dense chromium oxide is formed by isostatic pressing. Its density is very high. The main technical indexes include Cr2O3 content >94%, porosity <15%, volume density >4.24g/cm3, and erosion loss only 1/10 of compact zirconia brick. Used in the E glass furnace unit kiln, directly contact high temperature molten glass melt, wall, melting parts, high temperature parts, pool bottom, main channel, pool wall and pool bottom, transition channel, pool wall, etc..
- Q:Which is faster for heat transfer between corundum bricks and high alumina bricks?
- There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.
- Q:How do corundum bricks bind?
- Each refractory brick is provided with corresponding refractory mud, and corundum bricks are bonded with corundum mud.
- Q:What can zirconium sponge do for those industries?
- Zirconium metal, also known as sponge zirconium, silver gray metal, the appearance of steel, shiny; melting point 1852 points, sub points, boiling point 4377 density 6.49. Zirconium is easy to absorb hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxygen; at 1000 DEG C oxygen dissolved in zirconium can make its volume increase significantly. Zirconium is relatively stable in the air; powder zirconium is easy to burn; fine zirconium wires can be ignited by matches; at high temperatures they can be combined directly with dissolved oxygen, nitrogen and hydrogen.
