Q:What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
Q:who knows the uses of refratories?
Of course, the role of the refractory material is fireproof, generally used in large buildings. It can reduce casualties and economic losses caused by the fire. it also can be used on the chemical instruments. ! !
Q:How to divide fire rating of decorating materials ?
Decorating materials shall be divided into four levels according to combustibility. Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability.
Q:Which schools are the best schools in the world for learning knowledge about refractories?
Wish it helps you out.
Q:How many external wall thermal insulation fireproof material are there
External wall thermal insulation materials are generally divided by the burning grade, into class A, B grade. Grade A is non combustible material, grade B is combustible material. Class A which can be divided into thermal insulation mortar, bakelite plate, rock wool plate, foam cement plate etc.. Insulation mortar is relatively good, easy for construction, convenient, low cost, but its production process is too simple, so it is prone to fake. I recommend you to find a large manufacturing factory that posses complete procedure, for example, provincial production record, the provincial use record, municipal record, tset report at or above the provincial level, state fire proof report, design drawings of office building. product will not be safe if there is a lack of any of these documents. Burning level for henolic is uaually class B, but class A2 can be reached if a thin layer of mortar is applied on the suface,(A1 is the highest level of fire safety),intensity of phenolic is not high, finger pressing will leave a pit on it. if classified according to kilogram, raw material differs greatly every 10 kilogram. Rock wool is also classified by kilogram, general using 150kg wool. Rock wool are now comprounded with average strength. It will easily absorb water, having trouble applying paints. Foam cement strength is not high, easy to absorb water, It is not resistant to falling. It costs low, only used unless little profit can be made, Do not use it if worrying accidents would happen. These materials can be firstly burned, The palce the sample into water to see if it will dufuse at last. External wall should stand up to wind and rain. In terms of thermal insulation, they are almost the same, shows little differences on design thickness.
Q:What kinds of refractory materials that can resist 3,000 Celsius degree?
I think that graphite is the only one.
Q:What's the B grade fireproofing material?
Grade B: rubber and plastic, extrusion molding, polyphenyl, PEF. organics, extruded sheet, polyphenyl board, phenolic resin. Hairong modules (thermal insulating and fireproof material) can reach grade B1 in fireproof performance.
Q:Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?
There is no necessary connection between them. Different fire resistant ratings of bulidings require different fire endurance of different elemements of buildings. According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.
Q:what's the application of fireproofing abs materials?
a kind of ABS alloy shell, a toy of child, low load bearing, refrigerator lining, it can be processed into various wear-resisting sheets, plates,and has good electrical performance, it can be used as electronic components or auto parts, all kinds of insulation materials, it's easy to machining on the surface, so it can be made into designated special products (such as electroplate), and easy coloring, it can be processed into colorful products, also can be used as a fireproofing electrical appliance outer covering, adding alloy to it will improve its comprehensive performance, etc
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
No In the high school chemistry, the former is talking about the traditional inorganic material, the latter is belonged to the new materials.
