Light weight heat insulation refractory castable,Insulating castable,Insulation castable

Insulation castable is one of the unshaped refractory materials. It is made of refractory aggregate, refractory powder, binders and other additives. It is loose, No fixed shape,Has high liquidity, Casting and vibration molding,Can use directly or use after add appropriate water or other liquid. It is one of the new type refractory material of don't need calcination.

Construction way:casting+vibration moulding

Features:

1. Low bulk density.
2. Low thermal conductivity.
3. High strength.
4. Good thermal and insulation properties.

$Light Weight Insulation Refractory Castable$

Q: Technical scheme of refractory for refuse incinerator: Design of refractory for incineratorAccording to the condition of incinerator, the requirements of refractory, the temperature of each part and the temperature of outer wall of shell are discussed. The scheme for using refractory materials is as follows:The furnace body is made of two layers of structure, that is, 114mm thick clay brick is built near the steel shell, and the lining is made of 134mm thick graphite brick.

Q: How can refractory materials be divided?: There are many criteria for the classification of refractories.Just referring to a book about refractory.

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: Why the refractories should be waterproof and wetproof: The binding agent of many raw materials is water-soluble. It will be useless when meeting water.

Q: Refractories for iron-making blast furnace?: Vibrating materials, corundum brick and aluminum carbon brick will be developed. Taphole commonly use stemming, silicon carbide - graphite bricks, whose material is Al2O3-SiC-C. Medium and large sized blast furnaces in China use dense mullite bricks, castable, graphite brick. Common lining material for iron ditch is ramming mass. hearth and furnace bottom common use carbon bricks, semi-graphite bricks, charring silica bricks, corundum bricks. Blast furnace bosh and lower part of furnace stack commonly use mullite bricks.

Q: What is the interior fireproof thermal insulation material?: polystyrene foam board, glass fiber spraying, polyurethane foam, thermal insulation system of inorganic wall. Use "DY" inorganic active thermal insulation material, have small thermal conductivity, large heat storage coefficient, better strength and achieve better thermal insulation and energy-saving effect when used in wall . Wall should definitely not crack and hollow because of high temperature in summer. It doesn't crack and shed because it is influenced by stress during heat expansion and cold contraction in cold winter.

Q: What are refractory materials?: Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.

Q: What are the fireproofing materials of the external wall included?: According to the external wall thermal insulation materials, the external insulation materials is in general divided into Class A and Class B. The A class is non-combustible material. The B class is combustible materials. The fire disasters of the CCTV building and Shenyang hotel are both caused by the B level materials. Generally, the A level material will be used, and some prices are even cheaper than the B-grade material. A level is roughly divided into thermal?mortar, phenolic foam Board, rock wool board, foam cement board, and so on. I hope my answer will help you!

Q: Pals who know something about fire resistant material please tell me how many types of refractory material there are: There are a variety of refractory materials, each of different use. It is necessary to make resonable classification for refractory materials so as to facilitate scientific research, rational selection and management. There are many kinds of classification methods for refractory materials, including classification based on chemical property, chemical mineral composition, production process, material form and other methods. 1, according to the capacity of fire resistance: ordinary refractory materials: 1580 degrees C ~1770 C Advanced Refractory Materials: 1770 degrees ~2000 degrees c: Classification according to product shape and size: standard 230mm×113mm×65mm no more than 4 scales

Q: Refractory inquiries: Special refractories are new inorganic non-metallic materials developed on the basis of traditional ceramics and refractory materials.
