Calcined flint clay has been processed through a series of procedures, such as remove impurities, magnetic-selected to move iron and spraying drying etc. Water-washed kaolin has been used very effectively as functional filler in ceramic and so on.

Calcined flint clay is mainly used for manufacturing high-quality refractory products, refractory castable, sagger, kiln furniture, crucibles, ceramic fiber, precision casting sand, ceramics products, etc.

Features of calcined flint clay:

High refractoriness.

Physicochemical stability.

Volume density high.

Low porosity.

Low water absorption.

Fully calcined.

Low impurity content.

Pure white.

Q:what grades are fire resistance of fireproofing glass divided into?
Fire resistance of fireproofing glass is generally divided into three levels, class A glass can satisfy the requirements of fire resistance and thermal insulation at the same time. Class B, it's a kind of fireproofing glass that can satisfy the requirements of fire resistance and heat radiation strength at the same time. Class C can satisfy the requirements of refractory integrity, if you want to know more specific requirements, you can also surf the internet for a more detailed description.
Q:What is shapeless refractory with high performance?
The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
Q:What can red stone refractory do?
Classification is divided into ordinary and special refractories two major categories. Ordinary refractories are divided into acidic, refractory, neutral and alkaline according to their chemical characteristics. According to the special refractory material consists of high temperature oxide, refractory compounds and high-temperature composite materials in addition, in accordance with the fire intensity can be divided into ordinary refractory products (1580 to 1770 DEG C), advanced refractory products (1770 to 2000 DEG C) and special refractory products (more than 2000 DEG C). According to the product shape can be divided into block (standard brick, special-shaped brick), special shape (crucible, sagger, pipes, etc.) (fibrous silicate aluminum, zirconium oxide and boron carbide material) and indefinite shape (refractory clay, pouring material and ramming material etc.). According to the sintering process, the products are divided into sintered products, casting products and fused blowing products. The main varieties of in general and special refractory materials, common varieties are mainly the following: acid refractories have a larger amount of silica brick and clay. Brick is siliceous products containing more than 93% SiO2, the use of raw materials with silica, silica and other waste. The silica acid slag erosion ability is strong, but vulnerable to the erosion of basic slag, its softening temperature is very high, close to the fire, the volume does not shrink after repeated burning, or even a slight swelling, but poor thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Containing 30% ~ 46% alumina clay brick, with refractory clay as the main raw material, refractory 1580 degrees to 1770 degrees, good thermal shock resistance, which belongs to the weak acid refractory material, resistance to acid slag, widely used, is the largest production of a kind of refractory material.
Q:How much modulus is used as refractories material of sodium silicate.
Storage and use are very convenient, especially for mechanized and the evenly refractory material and the sodium silicatemodulus is generally...2. transportation. The appearance of product is pure white. Instant powdered sodium silicate, also known as instant sodium metasilicate.4 to 3, in powder form, automation. in the range of 3, hydrated sodium silicate
Q:The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide
1. corundum is the main component of alumina. 2. agate is the main component of silica. 3. is right. 4. glass is silicate. 5. solar cells are made from monocrystalline silicon. So 3.5 correct, choose D.
Q:What advantage and disadvantages it has compared to common fire insulation materials
Generally speaking, high fire resistance, non combustible Various standards for evaluation varies according to different types, which includes anti-corrosion, acid and alkali resistance, waterproof, anti termites and so on. I hope my answer can slove your problem
Q:what are the types of piping insulation material fire?rating?
according to China's national standard GB8624-97, the combustion performance of construction materials can be divided into several grades grade A: Incombustible building material: Almost no burning material. Class B1: nonflammable building material: nonflammable material has a good flame resistance effect. when it meet the open fire in the air or burnd at high temperature, it is difficult to spread quickly, and when the fire source is removed, the combustion stop immediately. Class B2: flammable building material: flammable material has a good flame resistance effect. when it meets open fire in the air or at high temperature, it will immediately burst into flames and easily cause fire spread, such as wooden column, timber roof truss, timber beam, and wooden stairs,ect.. Class B3: inflammable building material: No flame resisting effects, highly flammable, high fire risk. 2, external wall thermal insulation materials, in accordance with fire rating, can be divided into1) grade A combustion performance thermal insulation material: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite ect.. 2) class B1 combustion performance insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) combustion performance of class B2 insulation material: molding polystyrene board(EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:What is the quote of fireproof and soundproof materials used in KTV?
1. fire retardant, sound absorbing sheet,eggs,pyramid,sound-absorbing material, piano room, studio, KTV, with glue on the rear, 15 Yuan 2. bar, KTV, fireproof sound insulation cotton, sound-absorbing materials, studio, eggs, drum practice room, sound-absorbing and sound insulation materials, pyramid, 25 Yuan 3. fireproof wood excelsior absorbent, sound absorbing board, wall ceiling decoration materials, materials, theater, KTV, wood color fiberboard, 30 Yuan.
Q:Could you tell me the fire-resisting time of class B fire proof door?
Could you tell me the fire-resisting time of class B fire proof door?
Q:How can refractory materials be divided?
There are many criteria for the classification of refractories.Just referring to a book about refractory.
