Q:what's the application of fireproofing abs materials?
fireproofing abs material is quite good, its fireproofing ability is quite good, now it's sales in the market is very well, you can purchase as you want.
Q:What's the organzational structure of refractory material?
Although hacing same chemical composition refractory material products also is mineral organizer. There are differences in the type of mineral phase, high refractoriness under load, quantity and crystalline state. The organizing minerals and microstructure are reflected by folding strength, high temperature pit definite density torsional strength, high-temperature torsional strength and product property. But, for example, wear or crack may cause damage. The performance index can reflect the internal structure of refractory: the nature of the thermal performance---linear expansion coeffcient. And the mineral composition of refractory material depends on the chemical composition and process conditions, the heat capacity and temperature conductivity. If the processing conditions are different, the influence of chemical action, and thermal conductivity: represents the nature of the mechanical properties - normal temperature, high temperature compression strength, high temperature creep performance and elastic modulus. Chemical compositions are the basic characteristics of refractory, representing the nature of the density---porosity, corrosion occurred refractory materials in high temperature use As a result, the composition and quantity directly determines the performance of refractory, true density: representing the forming of high temperature performance --- refractoriness, high temperature volume stability, so you can't analyze the effect on the product performance just from chemical composition. The performance of various refractory materials are different. It must be emphasized that macroscopic organization structure of refractory material is also an important factor that affects performance; reflecting complexity of penetration---air permeability, thermal shock resistance and slag resistance. The main component is the foundation of refractory characteristics.
Q:Why can aluminium hydroxide not be used to make refractory material?
Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
Q:what is the Specifications Grading for Fireproof rubber insulation materials ?
External insulation materials, welded wire mesh matt external wall insulation, external wall thermal insulation mesh matt. 1,inorganic activel thermal insulation materials 2,silicate thermal insulation material 3,ceramic thermal insulation 4, gelatine powder polyphenyl granule, 5,teel wire gauze picking cement cystosepiment(Estazolam platepowder particles)6 extruded sheetXPX. 7,Rigid polyurethane coating at the scene, Polyurethane insulation board8,rigid polyurethane foam,9EPS foam board roofing materials. 1, a ceramic insulation board 2, xps extrusion board 3, perlite and perlite brick 4, vermiculite and vermiculite brick heating, air conditioning Material: Phenolic resins, polyurethane waterproof thermal insulation integration, sponge rubber, polyethylene, polystyrene foam, glass wool, rock wool Steel material: Polystyrene, extruded sheet, polyurethane panels, glass wool carpets and the like. Five inorganic thermal insulation materials: Foam cement, DY inorganic active insulation system super thin vacuum insulated panel for building external walls .
Q:What is the upper temperature limit for refractory materials?
The key depends on what refractories you use
Q:What are the raw materials of refractory concrete ?
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 parts of cement kilns are refractories used on?
In kilns.
Q:Who knows about the criteria of fireproof and thermal insulation materials?
1. thermal insulation materials with A-level combustion performance: EPS sea capacity module, rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. thermal insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), phenolic aldehyde, gelatine powder polyphenyl granule,etc. 3. thermal insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc. Such A-level insulation materials are only fireproof, the thermal insulation properties are worse than that of organic XPS \\EPS materials. Currently I think that the best insulation material should be EPS sea capacity module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The thermal insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range. I hope my answers help you.
Q:What are fire ratings of wall thermal insulation material?
Grade A material has no ignition and is material with thermal insulation effect, anti-combustion material. Currently it mainly refers to inorganic thermal insulation mortars of vitrified micro bead, hole-closed expanded perlite, rock wool,mineral wool,glass wool,cement base or gypsum base, inorganic thermal insulation mortars and self thermal insulation system of lightweight block. Grade B1 is nonflammable thermal insulation material, which is determined by fire endurance of this material. In addition, the division of the material of different parts is different! What is commonly seen, such as EPS / XPS insulation boards adding flame retardant through special treatment. Grade B2 is combustible thermal insulation materials, and what is commonly seen is EPS expanding polystyrene board and XPS extruded polystyrene board, that is, the general board. This material has low ignition point, and releases large amounts of harmful gases in the combustion process . Grade B3 is flammable insulation material. Thermal insulation material with polyphenyl foam as main material is commonly seen. Since this material is highly flammable, it has been eliminated external wall thermal insulation materials.
