Q:The structure of refractory material
Q:Can anyone tell me the requirements of the refractory masonry??
Kaolin is mainly composed of kaolinite crowded minerals that is in the shpe of tiny flake which is less than two microns, tube and folding flake. The kaolinite crowded mineral consists of kaolinite, dickite, pearl stone, halloysite, etc. and its ideal chemical formula is AL2O3-2SiO2-2H2O. The main mineral component of it is kaolinite and halloysite.In addition to the kaolinite crowded mineral, kaolin is accompanied by other minerals like montmorillonite, illite, pyrophyllite, quartz and feldspar. The chemical composition of kaolin contains large amounts of AL2O3, SiO2, and a small amount of Fe2O3, TiO2, and traces of K2O, Na2O, CaO and MgO, etc. The white pottery is made of kaolin. At present, the internationally accepted scientific name for kaolin is Kaolin which is derived from the kaolin mountain in the eastern suburb of kaolin village in Jingdezhen.Such special properties of kaolin as its plasticity,cohesiveness, certain dry strength, sinterability and firing whiteness make it the main raw material for ceramic production; properties like whiteness, softness, high dispersibility, and adsorbability allows it to be widely used the paper industry. In addition, the kaolin is also widely used in some industrial sectors such as rubber, plastics, refractories, oil refining as well as agriculture sector and cutting-edge technology for national defense. According to the purpose and requirements, kaolin can be processed and purified and it can be used to manufacture activated clay.
Q:What are the characteristics of thealuminium oxide refractory?
Alumina refractory are characterized by uniform granularity, mobility, good dispersity. And it has good acid and alkaline slag erosion resistance, high strength, abrasion resistance, high melting point, erosion resistance , anti-flush and excellent thermal shock resistance.
Q:what's the varieties of thermal insulation material with A level fire rating?
the main A level fireproof material is rock wool now (note:it is rock wool not mineral wool). A1 level fireproofing, now the largest producer is Taishi rock wool Co., Ltd.; hope my answer can help you, thank you.
Q:What are the new refractories?
Most are ordinary refractories.
Q:What are the main characteristics of the sic refractories?
1. The usage temperature of silicon carbide refractory is generally 1760 ℃ 2. The silicon carbide refractories can withstand dramatic changes in temperature, and a good thermal shock resistance performance. To prevent the cracking or breaking of lining refractories. 3. Under the conditions of high or low temperature, it can withstand a certain compressive stress. 4. Under the conditions of high or low temperature, it can withstand friction. 5. It can withstand the huge hydraulic pressure or buoyancy of the metal. 6. It can also withstand the effect of furnace gases to prevent the infiltration of other refractories and reactions.
Q:what is the fireproofing material of engine room? who knows it ?
1. The new type fire retardant coating in fire retardant coating, the expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder, etc. These inorganic component, is a major part of the thick coating type of fireproof coating, and they also are the major factor affecting the level of performance of fireproof coatings. The fireproofing thermal insulation properties of fireproof coating, is mainly determined by the fire back surface temperature of this factor, but also related to the fire endurance. If it reaches the same temperature for a longer time, it shows that it's fireproof thermal insulation is better, and the fire endurance therefore is higher. 2. The new fireproof board new fireproof board now is welcomed by the people and the important factor is its environmental protection, and with the increasing high-rise buildings, the fire protection requirements and strength requirements are also rising, it is a big challenge for the performance and standard of the fireproof board.. Now fireproof board is mainly used siliceous material or calcareous materials, and then mixed with the fiber material, lightweight aggregate, adhesives and chemical additives, it is not only be fireproofing, but also improve their thermal insulation performance, and light weight, good carrying capacity, good durability, no aging problem, more importantly, it is good in environmental protection.
Q:What kind of material is refractory fiber?
Refractory fiber, also known as ceramic fiber, is fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts.
Q:What is the function of refractory in ceramics?
It depends on what purpose you want to achieve. At the same time, part of special ceramics belongs to refractory. If is is to produce ceramic products, the aforesaid answers are very comprehensive.
Q:What parts of cement kilns are refractories used on?
These parts are decomposition furnace, smoke chamber, kiln, kiln hood, grate cooler, tertiary air duct and coal pipe.
