abrasive white fused alumina (WFA) for sand blasting 180 mesh

Q: What kind of flexible fireproof material is really good?: The best one is grade A fireproof material. A-class fire flexible material adopts clay, stone, sand, cement blocks and other inorganic powder and modifier and product density is 2327 kg/m3. Upon examination, the combustion performance of this product is in accordance with the grade A specified requirements and additional classification meets A s2, d0, t0 level requirements. According to GB 8624-2006, the combustion performance of product reach A2 - s2, d0, t0 level.

Q: what is the grading standards of external wall thermal insulation materials?: 1. combustion performance of insulation material rates A EPS sea capacity module, rock wool, glass wool, foam glass, ceramic foam, foam cement, perlite obturator, etc. 2. combustion performance of insulation materials rates B1 Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule3 combustion performance of insulation material rates B2 Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 A graded insulation material is fire proof, but its thermal insulation performance is not so as organic XPS \ EPS. I feel the best insulation materials are Hairong EPS module. it is both insulating and fireproof and cheap. Insulation materials in the domestic market each has its shortcomings. Choose of materials should based on actualities in construction.

Q: What's the fire?retardant material of roller shutter fire resistance door ?: They are composited by inorganic materials, and the main components are perlite, inorganic adhesive and other special formula. It has flat and smoothe surface, unibody and stronger strength after molding. It has owned Chinese and Taiwan strength patent. It is fireproof, sound and thermal insulating. It has passed tests of Tianjin Fire Research Institute and Beijing construction institute. It is an ideal product.

Q: What is the principal part of silicious refractory material: lightweight silica bricks, product with fused quartz, the silicon?dioxide content is generally greater than 93%, including silica?brick silicious refractory SiO2 as a main component of refractory products

Q: What are the characteristics of thealuminium oxide refractory?: Physical properties of refractories include structural properties, thermal properties, mechanical properties, performance and job performance. The structural properties of refractories include porosity, bulk density, water absorption, air permeability and pore size distribution. The thermal properties of refractories include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity and thermal emission rate, ect. Mechanical properties of refractories include compressive strength, tensile strength, flexural strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength and modulus of elasticity, ect.

Q: which kind of material should be used in fireproofing cabinet?: Natural stone,marble. advantage: Colorful, soft texure, natural and diverse texture, easy to cut or engraving molding. Disadvantages: Because it is a natural formation, tiny loose crackle is easily folded, because the stone is porous material structure, if sewage and waste water permeate in the structure in the process of production, transportation or construction, it's difficult to clean and easy to crack. In daily cleaning, it is inevitable that there will be some residue left, and dirt is filled into crack under the wiping of rag and becomes a breeding ground for bacteria. 2, granite. advantages: Granite has big density and high hardness, with wear-resistant surface, it's one of the most common materials for family decoration. Compared with natural marble, it can be used in the materials of kitchen countertops, and granite has good anti-bacterial regeneration ability. Disadvantages: As the cabinet table material, natural stone is usually not very long, so in order to produce a long overall table (especially U-shaped, L-type table), it will certainly exist joints, which are also easy to hide dirt. 3, artificial stone. advantages: Artificial stone has richful lines and colors, and it can be comparable to stone, it's non-toxic, non-radioactive, easy to clean, and can be truly seamless splicing. it belongs to economic environmentally friendly material. Disadvantages: Artificial stone belongs to the processing industry, and has low technology requirements, The inferior products of many small companys are fulled in the market and damage customers' interests. There exist faded color,poor aging resistance,oil stain and other issues in affordable products.

Q: What are the insulation fireproofing materials?: Asbestos is the most common. Asbestos containing zirconium and made of the mixture of zirconium aluminum and silicon through wire drawing is better. Of course, some are made directly from natural things which can withstand 1400 degrees for over 30 seconds while the internal temperature had no significant change, and withstand 1400 degrees for over five minutes while inside temperature increase does not exceed 5 degrees.

Q: What refractory material does cupola lining use?: In order to improve the service life of the lower wall and the bottom leather, dense and high alumina brick can be used for masonry. The front furnace is composed of the bottom, the wall and the top. The top of the furnace is vaulted or hanging flat roof. The front furnace body is usually made of clay brick and high alumina brick, and the bottom work floor is rammed with ramming material. The material is the same as that of cupola furnace. The bridge and the front guard taphole, slag hole and other parts due to erosion by high temperature molten iron and slag erosion, lower service life, frequent repairs. Large blast furnace adopts hot blast or oxygen enriched blast, which has higher temperature and higher production capacity... The damage is faster, and it is hard to maintain production by using clay brick or high alumina brick. Should be used aluminum, carbon or corundum refractory silicon carbide castables pouring or tamping, so that the integrity of good, high strength, corrosion resistance, and therefore significantly improved service life, generally up to one year or so. Refractory materials, including chimneys and spark traps, are used in other parts of the cupola. The chimney and the cupola shaft directly connected with the shell made of steel plate, lined with ordinary clay brick, can also be used ordinary refractory castable pouring. The chimney is provided with a furnace heat exchanger, which can preheat the air to 300~500 DEG C, and the spark collector is used for catching the hot coke and dust particles brought out in the flue gas. The chimney at the top of the reflector (cover) by plate welding, can also be used to cast iron, its lining refractory coating or spraying paint.

Q: The manufacturing technique of refractory material: The major components of alkaline refractory material include magnesium oxide and calcium oxide. The commonly used alkaline refractory material is magnesia bricks. The magnesia bricks with 80%～85% magnesium oxide has good resistance to basic slag and slag and higher refractoriness than clay bricks and silica bricks. It is mainly used in open hearth, oxygen blowing of converter, electric furnace and smelting non-ferrous metal equipment and other high temperature equipment. Refractory materials applied on special occasions include high temperature oxide refractory materials such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, etc., refractory compounds such as carbide, nitride, boride, silicide and sulfide, etc., and high temperature composite materials, including metal ceramics, high temperature inorganic coating and fiber reinforced ceramics, etc. Consult and find reference for efractory materials production equipment, go to http://hi.baidu.

Q: Introduction to refractory material: The best way to learn is on-site contact. If for produing purpose, it is better to ask teh leader of a plant. If for application, go to steel mill (cement plant, glassworks, etc.) to learn and look up information. Theory alone is of no help.
