Q:What are included in roof thermal insulation fireproofing material?
Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.
Q:What are the common refractory insulation cotton material?
I know less about this, I hope the following will help: Fire resistant thermal insulation material mainly refers to inorganic thermal insulation material and compround thermal insulation material. According to the shape can be divided into: Fibrous finishes, slag wool, rock wool, glass wool, aluminum silicate cotton. ceramic fiber, micro pile of diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete etc., foam like bubble glass, volcanic ash glass, foam clay, foaming concrete, paste powder polystyrene particles insulation slurry
Q:Does anyone know what is a lightweight refractory material?
Light weighted castable is one of the kind.
Q:What are the meanings of azs, 34% and ec in fused brick?
The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
Q:How to understand qualitative and qualitative refractory materials?
Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
Q:What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
Q:What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?
The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.
Q:What are the materials of class A fire resistant window?
Fixed class A fire resistant window should be made up of steel frame, steel casement, and fireproof glass. Fire windows, made up of steel frame, steel casement, and fireproof glass, refers to window that isolate and stop the fire from spreading. Fire window is named according to the main materials of the frame and casement. Window frame is made up of steel and casement wood, vise versa. I hope it is useful.
Q:It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
Q:How about the prospect of refractory material?
Due to the rise of raw material, the prospect is not good with inflation, lower prices and decreased profits. The product requirements have been enhanced and there is vicious competition. Therefore, it is really bad.
