Q: Who knows how many fire heat preservation material are there?: They can be divided into wood fire, steel fire and stainless steel fire. Wooden fireproofing material is light weight, easy for installation and second decoration, as well as all types of civil construction and some industrial buildings. It can be realized through inorganic insulation materials, such as glass wool, rock wool, foam glass etc.. The phenolic foam materials inside organic foam material is more special. Phenolic foam does not only have a good thermal insulation performance, but also can be combined with steel and other materials, to achieve a class A fire retardant level. Class A thermal insulation include: 1 thermal insulation materials with class A combustion performance Fire insulation materials of fire barrier zone can use class A material with class A combustion performance in rock (ore) cotton, foam glass, inorganic thermal insulation mortar.

Q: How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?: The relative production is lower and material cost is higher, the lining of the refractory is thicker: 1, determine the weight of the refractory material according to the main structure of the bearing capacity, to prevent damage to equipment, fire-proof material damage after the surplus size and thickness of the thermal conductivity of refractory materials, the smaller the effective volume, production output, the cost of materials) to consider the selection of refractory material thickness. 3 from the point of usage (usage cycle, relative usage cycle is longer, because under the condition of invariable in the device's overall dimensions of the refractory lining thickness to determine several basic principles, according to the volume of the weight computation of refractories and refractory thickness, these items must be fully consider the pros and cons before decided. 2 according to maximum temperature that shell can withstand.

Q: How to detect the acid resistance of refractory? Is there any standard? Thank you: There is a standard. However, the range what you said is a little big, it's difficult for me to say. But though the scope is a bit big, it should be: You can check the industry standard network, to see whether you can check it.

Q: What are the applications of refractory busway?: Refractory busway is designed for the power supply in fire-fighting equipment, and it can not be used for other purposes. As the generatrix has good heat resistance, thermal insulation, and the heat of the busway can not be emitted, it can not be used long-term at full capacity. In addition to fire-resistant busway, ther bus lines can operate full-load in long term.

Q: Urgently!! Refractory problems, online, etc.: I feel that is the coating package, the coating of water is too large, the retaining wall in fused powder hydrated, can not produce strength under high temperature. What do you think?

Q: What substitutes are available for high-end refractories in addition to zircon sand?: Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..

Q: What are fire?ratings of wall thermal insulation material?: 1.thermal insulation material with grade A combustion performance: YT inorganic active insulation material for wall thermal,rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2.thermal insulation material with grade B combustion performance: Extruded polystyrene board(XPS)after special treatment/polyurethane(PU) after special treatment, phenolic aldehyde,gelatine powder polyphenyl granule, etc. 3.thermal insulation material with grade B2 combustion performance: Molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.

Q: Fire insulation and fireproof insulation board materials What is the difference in performance?: Fireproof materials and insulation materials, refractories not the same thing, but some insulation materials are fire resistant and refractory. Fireproof material is a synthetic material characteristics of fire resistance or the material itself is a high temperature resistant, flame-retardant. Fireproof materials are mostly used for construction, playing an important role in fireproof today in various forms.

Q: On the problem of making refractory materials: Refractories mainly depend on their high melting point characteristics. The refractory market is mainly Magnesium Oxide material.

Q: What's the A grade fireproofing material?: A grade fireproofing material: 1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire?retardant?coating; 9. fire-proof?sealing?material.
