$Light Weight Insulation Refractory Castable$

Q: Who knows the classifications of magnesia refractory?: Magnesia chrome series products: The main ingredients of magnesium chromium series are MgO and Cr2O3. Periclase is the first phase and magnesia-chrome spinel is the second phase. Products belonging to this series are magnesium chrome brick and chrome magnesia brick. The main ingredients of magnesium aluminum series are MgO and Al203. As they generate MgO and Al203, all magnesium chromium series products contain magnesia material. magnesium calcium series products The main components are MgO and CaO. They have high melting points, which are important magnesia materials. 5, magnesium silicon series products: The main component of magnesite series is SiO2, when the C / S<5, SiO2 and MgO generate MgO.Al2O3 (forsterite). From the perspective of microscopic mineral, main products of pure aluminum series include magnesium aluminum brick, periclase spinel brick, corundum spinel brick and aluminum-spinel castable in unshaped materials. I hope this answer can help you.

Q: How to hang the suspended brick in the refractory masonry?: First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.

Q: How long is the fire resistance time of the AAAfire resistance rolling shutter door?: How long is the fire resistance time of the AAA fire resistance rolling shutter door?

Q: Who knows what kind of fire prevention materials are there?: Plant use general steel structure more often without too much modification. If there is a need for modification, boards which can meet the requirements of fireproof are suitable, such as gypsum boards and aluminium sheets. As for coating, it is favorable to use coating that has fine powder, high density and better sealing. Hardening agent mainly depends on the specific requirements.

Q: Ask some questions about refractories: Is a kind of refractory material, jargon called hook materialThe iron runner: a combination of the super high Los resistant technology, aluminum and corundum, silicon carbide and other raw materials, to high-quality composite binders and additives, strict proportioning, elaborate. The utility model has the advantages of good slag resistance, good thermal shock resistance, long service life, convenient use, simple construction, and obvious reduction of labor intensity of workers.Application: it is suitable for blast furnace tapping system.

Q: What defect does fused cast refractories have ?: The impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement.

Q: What are the technical requirements for refractories?: How high the temperature is and what is this refractory?

Q: What are Grade-A waterproof inorganic thermal insulation materials?: 1. Foam ceramic insulation board Foam ceramic insulation board is made of inorganic ceramic material by high temperature baking and is called ceramic insulation plate for short. 2. Composite cement foaming insulation board With cement, fly-ash and micro-silica, composite cement foaming insulation board is a kind of hole-closed lightweight hydrophobic insulation board made by foaming, maintenance,cuttign and processing. 3. Aerated concrete panel Using lightweight material, silicious material and foaming agent and so on, aerated concrete panel is a lightweight concrete panel made by high pressure steaming. 4. Rock wool board With natural igneous rock as material and thermosetting resin as binder, rock wool board is a panel made by melting in high temperature through centrifugation. I hope it can help you.

Q: What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?: Hello there. Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.

Q: I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?: Looking for refractory materials network, you can conduct online transactions, funds guaranteed
