Brief introduction:

Refractory materials can be divided into shaped refractory products(Such as: Refractory brick ,Fire clay brick,High alumina brick, Heat insulation brick,Ceramic fiber products ect) andunshaped refractory materials(Such as:Refractory castable, Plastic refractory, High temperature refractory mortar ect), Widely used in metallurgy, petroleum, chemical industry, Cement, Glass, Casting,carbon,building materials, machinery processing, military, etc.

Refractory raw material: The chamotte, Calcined flint clay, Calcined kaolin, Sintered mullite,Bauxite,flint clay, aggregate, fused mullite

Made process:

Made from the natural high quality bauxite, our product is through multi-level homogenozaotpm and then calcined at about 1750 degree. it possesses many good characteristics such as high bulk density, stable quality, good thermal shock resistance, small index of high temperature creep and good resistance to cheamical corrosion, it is an ideal raw aterial for the following refractory products like a variety of shaped and unshaped refractories, advance ceramic asanitary ware body, precision casting models and so on.

Application: metallurgy, petroleum, chemical industry, building materials, machinery processing, military, etc of thermal technology equipment.

Features: High strength, good thermal stability, impact resistance, scouring resistance, wear resistance, long service life by the combined technology of low cement and adding superfine powder and efficient dispersant. Excellent raw materials and high temperature performance, castable refractoriness reaches 1790 °C. Mixing by machine, convenient construction, the construction period is greatly shortened, and the economic benefit is remarkable.

Purposes: Cement kiln preheater lining, cooling machine lining, pipe lining, coal injection gun wrapping, kiln mouth, and high temperature parts. Prefabricated into various sizes and also can be applied to spraying construction (preheater lining).

Usage: add water to form mortar or make prefabricated block, semi-dry method spraying construction is available for spraying type.

Storage: 25 kg/bag sealed packaging at room temperature for 3 ~ 4 months

$Mullite Castable In Refractory Cement$

Q: Which manufacturers have the best fire-proof materials with light weight?: It now appears that asbestos is the best among the most common fireproof materials. But asbestos also has great harm, especially to lung. Shanghai Xinlong Fireproofing Material Co., Ltd. and Hubei Boyue Lightweight Material Co., Ltd. were established in 2009. The company is located in Wuhan Biological New Town and covers an area of ??30 acres. The company is a specialized enterprise which is mainly engaged in the research and development, production, sale and construction of lightweight partition board, lightweight fireproof wall panel and lightweight wall panel. The two companies are both good.

Q: What are the materials of insulation firebricks?: The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.

Q: How long does it take for refractory cement to solidify?: 1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.

Q: How many hours of the fire endurance time of the rock wool laminboard?: Hello. The fire endurance now on the market is generally about two hours. The 50mm color steel sandwich version of Bo magnesium rock wool, with refractory time being five or six hours, is very good.

Q: For refractory knowledge. What is the ratio of clay ramming?mass?: Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK

Q: Why does refractory need to add coarse firstly and then add fine aggregate?: Binding agent can wrap particles and improve binding effect.

Q: I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad: You don't give a cent to this question, no one will answer it

Q: How to divide fire resistant level of fire door?: Fire resistant level of fire door【Class A fire door】. Class A fire door is also called complete fire door. It can meet the requirement of fireproof thermal insulation and refractory integrity at the same time in specified time. Fire resistant levels are 0.5h(Grade C), 1.0h(Grade B), 1.5h(Grade A) and 2.0h, 3.0h. 【Class B fire door】Class B fire door is also called part heat insulation fireproof door. Its requirement of fireproof and thermal insulation performance is 0.5h. Refractory integrity levels are 1.0h, 1.5h, 2.0h and 3.0h respectively. 【Class C fire door】Class C fire door is also called not thermal insulation fireproof door. Ther is no requirement of its fire resistance and thermal insulation. It only meets the requirement of refractory integrity in specified refractory time. The grading of refractory integrity is 1.0h, 1.5h, 2.0h and 3.0h respectively. There is the content of not thermal insulation fire door in British BS standard.
