1. Description & Application

Widely applied to high quality fire resistance material and coating of metallurgy industry,hot working

material stabilizer of military industry,lead of light industry,carbon brush of electrical industry,electrode of

battery industry,and catalyzer and additive of fertilizer industry.After further process,scale graphite can be

made into the following high-tech products such as graphite colloidal graphite,graphite compacting material

and composite material,graphite products,and graphite anti-friction additive,which are becoming important

nonmetal mineral materials in every industry.

2. Technical Specification

Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: Solid wood logs are necessary. If it is the type of smoke free material, it will not be necessary. You'd better confirm it with the port of destination. Vietnam has the requirement to smoke

Q: Which industry does refractory belong to? Does it belong to construction industry?: It belongs to material, and after all, more than 60% refractories are used in metallurgical industry. If you insist on classifying it, it belongs to supporting industry of metallurgical industry. Refractory industry itself is independent.

Q: Refractory materials are needed for casting metallurgy.: High quality refractory materials can not be separated from the process of smelting metal and casting moulding, because the quality of melting furnace, iron / steel ladle directly affect the chemical composition of the metal liquid, and exert irretrievable influence on comprehensive quality of castings. Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, coating material and light insulation material etc.

Q: what kind of fireproof materials is used for high rise buildings?: steel is recommended As a form of high-rise building structure, steel is widely used especially in the ultra-high-rise and long span construction showing strong vitality, for its high strength, light weight, and good extensibility, resistance to shock and short construction period. The mechanical strength of steel decreases with rising temperature at about 5000 ℃, decreasing about 40%-50%. the mechanical properties of steel, such as yield points, compressive strength, elastic modulus, and load capabilities have declined rapidly , quickly losing their ability to support, leading to building collapse. Therefore, it is imperative to protect steel structures. Brushing or spraying the coating on the surface of steel structure to prevent burning and insulate heat. It also prevents undermining the rolled steel from rapid temperature elevation and avoid collapse of building for lose of supporting capacities.

Q: How long is the duration of fire resistance that fireproof door of level B can endure?: According to the duration of fire resistance, fireproof doors can be divided into three levels, namely level A,B,C. And accordingly, the duration of fire resistance of them should not lower than 1.20h, 0.90h and 0.60h. Fireproof door, a door that can meet the requirements of fire resistance stability, fireproof door integrity and thermal insulation at a certain time, is a fireproof separator which is located in fireproof partition, emergency staircase and vertical silo. Apart from functioning as a common door, a fireproof can also prevent the spread of fire and smoke in a certain period to make sure that people are safely evacuated.

Q: Which one is better, fire-resistant wood or steel?: According to my understanding. This fire-resisting wood is better. Iron birch. The iron birch is three times harder than the oak, twice as hard than ordinary steel. It is the world's hardest wood which is used as a substitute for metal. The Soviet Union have used iron birch for the manufacturing of roller ball, bearings and it is applied in yachts. Iron birch has some wonderful characteristics. Since it has very dense texture, once put in the water it will sink; even if it is soaked in the water for a long time, the inside still remains dry. The iron birch is twice harder than the steel, it doesn't mean that its hrc value is twice of that of the steel. HRC means test load 1471.1N (150KG-F) using a diamond cone head with the point angle of 120 degrees to press. The calculation formula HR= (K-H) /C,K=0.2MM,H is the depth of indentation after releasing the major load. C= 0.002MM, so HRC100 is a limit value, then H is 0, which means that even the diamond will not drill into it. Generally the hardness of bearing steel is about HRC60. Iron birch is the championship among trees in terms of hardness. The bullet hit the wood is like hitting on a thick steel plate and the wood will be motionless. So, it is known as a tree harder than steel. I hope my answer will be helpful to you.

Q: Does anyone know what is a lightweight refractory material?: The volume shrinkage is larger, and the corrosion resistance is higher at high temperature. A lightweight refractory material, used as thermal insulation material in industrial furnace and other thermal equipment, has poor wear resistance, weak mechanical strength and small volume density. Compared with ordinary refractory bricks, the lightweight refractory with low thermal conductivity has higher porosity.

Q: What material is used for making refractory stone bowl?: Stone pot is carved from high-quality natural refractory stone with a professional way. It has attractive and diverse appearance, and it is hard, heat fast, not stick food. Now it is used in many hot pot restaurants.

Q: What kind of refractory decorative board has good quality?: Formica, Grignard, Wilsonart, Yami Home, Germany Board and Priscilla Board are all good choice. They are the high-end brands in fireproof?panel. Hope it is helpful to you.

Q: What are the construction fire-proof materials?: 1. fire?retardant?coating 2. fireproof?panel 3. fire proof and sealing material 4. flame resisting decorative materials 5. Green fire prevention materials
