Q:What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?: The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.

Q:What are the materials of class A fire resistant window?: Fixed class A fire resistant window should be made up of steel frame, steel casement, and fireproof glass. Fire windows, made up of steel frame, steel casement, and fireproof glass, refers to window that isolate and stop the fire from spreading. Fire window is named according to the main materials of the frame and casement. Window frame is made up of steel and casement wood, vise versa. I hope it is useful.

Q:Manganese steel belongs to refractories: Material wear and other harsh working conditions, extrusion, there will be work-hardening phenomenon rapidly on the surface. The most important feature of manganese steel is that it is not refractory under a strong impact, and under extrusion conditions, part of it will be fractured. The main form of damage is wear and consumption: It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃, mainly used to endure impact. Manganese steel is a kind of high strength steel, which is free of deformation, so that it can remain austenite good toughness and ductility at heart while keeping good wear resistance at the same time on hardened layer. Refractories are

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 are the classifications of refractory? Which category does steel ladle castable belong to?: In addition, it can be divided into refractory, shapeless refractory material. And it can also be divided into acidic refractory, basic refractory and neutral refractory. If you want to know more, you can ask thme. In fact, every company has different refractory clasifications. There are more clasifications in Huaheng.

Q:What's the frequently used refractory material?: What's the frequently used refractory material in the market? It is usually classified into four categories: Common Refractory: silica?brick, semi-silica brick, refractory fireclay block, high alumina refractory brick, magnesia brick, etc. Unshaped Refractory: repairing?mass, ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, sling refractory, refractory coating, lightweight refractory?castables, stemming, etc. Special Refractory: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia, etc. Fireclay Insulating Refractory: diatomite product, asbestos product, insulation?board, etc.

Q:which is better as household fireproof material ?: the thickness recommended is 1mm or more # 304 stainless steel plate, refractory corrosion-resistant, easy to clean. It now appears that among the most common fireproof material, asbestos is the best. But the asbestos harmful effect is also great, especially for lung damage. Now on the market, the polyurethane, polystyrene, rock wool glass wool, phephenolic aldehyde fireproofingthermal insulation board. But now the phenolic aldehyde fireproofing thermal insulation board has superior performance! phenolic aldehyde containing only carbon, hydrogen and oxygen atoms, when subjected to pyrolysis, except small amounts of CO gas, the other will not produce toxic gases, maximum smoke density is 5.0%.

Q:The development prospect of fire-resistant material: Exported bulk material amounts to exported raw material/ To protect domestic resources, many countries have set linitations on the magnesium content in shapeless refractory material and lisences.

Q:What are the use of fire-resistant material and admixture?: Generally speaking, there are several admixtures: 1. Water reducing agent. It can ensure basic refractory castable flow value and significantly reduce its water mixing amount sodium hexametaphosphate and sodium tripolyphosphate 2. Plasticizer. It can increase plastic refractory mixture and enhance the ability of bentonite clay mud material stress strain 3. Gelling agent. It can make the colloidal solution (or suspending liquid containing solid particles condensed gelling agent 4. Dispergator. It can turn condensation or reunion colloidal particles (particles) into sol or uniform dispersion suspended particles and make the thick colloid free stream sol said scattered coagulant peptizer 5. Coagulant. It can shorten the stereotypes refractories condense sclerosis NaOH Mars between aluminum hydroxide, etc. 6. Retarder. It can delay the stereotypes refractories condense sclerosis between citric acid tartaric acid, etc. 7. Delayed coagulant. It can make setting fire-resistant materials contain binder by set out the condensation hardening effect between calcium aluminate cement, etc. 8. Foaming agent. It can reduce the liquid surface of power to produce uniform stability as rosin soap bubble resin fat saponin and so on. 9. Antifoaming agent. It can make fast setting fire-resistant material mixing or shock in produce bubbles escape alcohol fatty acids, such as 10. Shrink agent can reduce or prevent the refractory materials used to produce contraction type heating said silicon powder stabilizer or volume expansion agent, etc. 11. Preservative. It can keep setting fire-resistant material stored on construction performance change or change oxalic acid citric acid, etc. 12. Inhibitors. It can inhibit stereotypes refractories ingredients contain iron or iron compounds and acidic reaction caused inflation to produce hydrogen bond CrO3 diacetone alcohol, etc. I hope it can help you.

Q:What are the construction fire-proof materials?: 1. fire?retardant?coating 2. fireproof?panel 3. fire proof and sealing material 4. flame resisting decorative materials 5. Green fire prevention materials
