- Q: Why can aluminium hydroxide not be used to make refractory material?
- Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
- Q: How to understand qualitative and qualitative refractory materials?
- Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
- Q: What problems should be paid attention to while using refractory materials under a controlled atmosphere?
- Pay attention to the performance of the materials, and the use of non oxide materials!
- Q: What is the strength of high strength refractory material?
- Refers to constrcuting through ramming, and a refractory materials that is hardened in temperature higher than normal. mixed through a certain grade of refractory aggregate, powder, binder, additives, water or other liquids. Can be classified into high alumina and fireclay, magnesite, dolomite, zirconium and silicon carbide by the standard of texture.
- Q: What's the maximum temperature that the refractory ceramic fiber cloth can endure?
- Ceramic fiber cloth is high temperature resistant and its continous use temperature can be up to 1000℃. It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; and it is easy to install.
- Q: What high-molecular polymers can be used as fire-resistant material binder?
- Melamine resin should be compounded with fire-resistant material and acrylic acid material is easy to burn. But high-molecular polymers can be used along with the above two. Polysulfone is featured by heat resistance and high temperature resistance. Polyurethane is difficult to process and compound with fire-resistant material. Phenolic resin is not easy to burn. Epoxy is expensive and self-extinguishing once away from fire.
- 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: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- Of course, there are also some docks that need not be fumigated! But also according to the requirements of the port of destination guests, because customs clearance may be proof of fumigation!
- Q: what should be paid sttention when buying the refractory?
- solve the resources and the cost as much as possible. Accurate understanding and knowing the material temperature changes of various partsin order to choose the appropriate refractories. 4： 3, work performance, for example, take measures to ensure the overall life, and it is a very good buying principles: melting in high temperature metal erosion. These are the four major problems to consider when using refractory. You can choose low prices and low transportation costs of materials to meet the basic principles under the conditions described above. 2.carefully observe the material to prevent the desturction and reducing the costs. according to the structure of furnace, reasonable coordination of all parts of the material, fully take the advantages of material characteristics and strive to develop the recycle, to avoid the destruction of the materials.1. the working characteristics and the sport condition and analyze the reason of destroying the material, which can not only gurantee the product quality and reduce the expenses, get familiar with the chemical component and physics of the material.
- Q: Which refractory is better for building 1500 degree kiln ?
- High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.
We enjoy convenient access to major transportation networks. Furthermore, all our products are manufactured with advanced equipment and strict QC procedures in order to ensure high quality.
