Q:The manufacturing technique of refractory material: Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank

Q:Who knows the texture of fire-proof wooden door material?: Steel door, wooden door or steel wooden door can be inset fireproof laminboard, such as rock wool, perlite. Perlite (fireproof doors filling material, fireproof doors raw material) using for fireproof door core is mainly used for the filling material of fireproof doors and security doors. Fire protection, thermal insulation, good sound insulation effects, and higher performance than aluminum?silicate?wool and rock wool. The combustion performance of perlite using for fireproof door core reaches class A non-combustion, which is new type of fireproof doors filling material with characteristics of low cost, good fireproof performance and excellent environmental protection performance. The advantages of fireproof door core perlite as fireproof door filling material: 1, Good fireproof performance, so it has a function of fire prevention. Environmental protection: all materials are environmentally friendly products. Pollution-free: the product is composed of glass fiber reinforced materials and inorganic binder. 2, with characteristics of non-flammable, non-explosive, water-resistant, oil-resistant, chemical erosion resistant, non-toxic and good mechanical strength, etc. The product can be used for mechanic processing like sawing, drilling, gouging, etc. High fire resistance, in the simulated combustion tests, it doesn't deform when the flame temperature reaching 800 degrees, has good fire retardant and fire-resistant properties. 3, product material is cheap, suitable for all kinds of fireproof materials. Perlite fireproof board is made by pressing the expanded perlite powder and high temperature fireproof adhesive through mould, suitable for the filling material of fireproof wooden door and fireproof steel door, which is the substitute products of aluminum?silicate?wool and rock wool. 4, has advantages of light volume-weight, high refractoriness, strong compressive strength, small thermal conductivity, non-flammable, non-toxic, tasteless, non-pollution, etc.

Q:What dose the fireproof and thermal insulation material include?: Protective cloth, fireproof cloth, plastic coated cloth, PVC tarpaulin, flame retardant cloth, duct cloth, automobile tarpaulin, PVC protective cloth, the freight yard covered cloth, PVC plastic coated cloth, Industrial Canvas, widely used in automobile tarpaulin, trains covered cloth, ships covered cloth, open-air yard covered cloth, industrial and agricultural covered cloth ; used in glass, timber, fertilizer plants, steel plants, mechanical hardware factories, feed mills, grain storages, container plants, oil refineries plants, packaging plants, paper plants, air conditioning plants, logistics, ore factories, fleet, rail and sea fields, etc.

Q:Is there vermiculite in refractory?: Vermiculite is usually used as lightweight material in refractory field, and its volume density is about 0.5.

Q:Classification of porosities in refractories and their effects on properties: Effect of apparent porosity on properties:The porosity is high, the volume density is low, the structure become more loose, generally low strength, corrosion resistance worse (slag infiltration and erosion along the hole toward the inside), but to improve the thermal shock resistance (resistance to thermal shock and not damaged).

Q:What's the difference between refractory metal raceway and fireproof raceway?: Hello, I'm very glad to answer your question. As far as I know, anti-fire groove box is made by the polymerization reaction of high polymer material and halogen-free flame retardant polymeric material. It possesses excellent mechanical properties and environmental protection property, nice appearance, and diversified colors. As a kind of fully enclosed cable bridge, it is applicable for communication signals, and laying of computer cables and control cables of highly sensitive systems. When used in heavy corrosive environment and outdoor dust environment, it has good protective effect on cables. It boasts many advantages of fire retardance (fire resistance rating is above B grade), corrosion resistance, anti-aging, high strength, light weight, and easy installation. Hope my answer is helpful for you. Hope my answer can be accepted.

Q:What are the fire endurance requirements of class A fire resistant door ?: Hardwares are professional fire resistant lock, fireproof?door closer, fire hinge, handle, latch and sequencer, and they can also be configured according to user needs. Fire resistant time of class A and B fire resitant door is 12h and 09h respectively. It can also be customized according to customer needs into a variety of non-standard specifications. Steel fire door is developed in accordance with the national standard GB12955-2008, and in line with ISO3008, BS476 standards. Requirement: fire endurance should meet the A,B and C fireproof requirements respectively. You can also choose to install hold-open door device to leep the door leaf usually in open. Doorframe and door leaf is made up of imported or domestic quality electrolytic steel plate, electro galvanized steel plate or stainless?steel plate, filled with quality expanded perlite fireproof?panel which can withstand high temperature above 1200 ℃. The surface is processd with electrostatic spraying plastics, and auxiliaries are stainless steel fire resistant lock (or pipe shaft lock ) , galvanization for steel (or stainless?steel) fire hinge, domestic(or imported) door?closer.

Q:how does the fire endurance of first rate fire resistant window?: Not less than 1.5 hours

Q:Development trend of refractories: Mullite Matrix clinker. There are higher requirements of kaolin and refractory annded life, it should be able to grind medical industrial raw materials alumina, vacuum extrusion molding, high temperature roasting and smelting from unshaped refractory material a good thermal mechanical properties in the kiln and has good application prospect; 2, Dong Qingshi clinker. With kaolin and magnesia as raw materials, wet grinding, vacuum extrusion, and then high temperature calcination, furniture has a very good prospect; 3, magnesium calcium sand. Because of the development of clean steel, low carbon steel, high oxygen steel and stainless steel, the basic importance of free calcium oxide refractories is supported; 4, fused eutectic composite. Bauxite based fused corundum, bauxite based fused mullite, bauxite based fused mullite zirconia, fused corundum zirconia fused zirconia, Magnesium Oxide and other materials have been developing rapidly; 5, high density spherical hollow mullite aggregate. The wall thickness of the shell of the 0.2 - 1.5 - 5 mm, diameter 40 mm, smooth surface, can not be uniform, spherical shell, this may be a double, a prominent part of the surface can be dense, can also be used for hollow casting material, not only can improve the insulation performance of the material, in order to reduce the volume density. Instead of destroying its strength.

Q:Who knows the fire endurance of B-level fireproof doors and windows?: Rock wool board of B-grade fireproof doors keeps 46mm in thickness, doors that are generally used in relatively common fire fighting access, while A-grade fireproof doors are generally used in machine rooms, warehouses, oil depots and other important fire fighting access and flammable and combustible pulbic places. B-grade fireproof doors are more widely used than A-grade fireproof doors.
