Q:Application characteristics of high alumina brick

Thermal shock stability. In high alumina brick products, the stress concentration is due to differential expansion when the temperature of refractory brick changes. Therefore, the high aluminum brick products than clay brick products thermal shock stability is poor, general water temperature only 3 - 5 times.

Q:What is the difference between corundum and high alumina??

The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.

Q:What are ordinary bricks, refractory bricks, hollow bricks?

Hollow brick is divided into cement hollow brick, clay hollow brick, shale hollow brick. In March 2011 Yunnan Yingjiang earthquake occurred in 5.8, the use of cement hollow brick houses collapsed and killed several people, due to safety concerns that Yunnan intends to disable the cement brick, Shandong Qingdao in the construction of real estate has also been halted the use of cement hollow brick. Professional claims in the construction industry argue that the prohibition of the use of such statements is unscientific and unprofessional. Misleading the public, it must be corrected. Hollow brick is only a kind of building material, and it is no problem to use it in scientific way. Hollow brick in use is very scientific, high quality requirements, the investigation of the foundation is suitable for the use of hollow bricks, how to design, construction, cement and other related ingredients, there are no problems. According to strict procedures, scientific use, strict implementation of relevant national standards, the use of qualified hollow bricks, there is no problem. Similarly, if the use of solid bricks does not strictly comply with the relevant standards of the state, the same will be a problem.

Q:What is the difference between metal compounds and metal solid solutions?

A series of intermetallic compounds occurring between transition metals in intermetallic compounds. The most important are L sigma sigma phase and ves phase, they are topologically close packed (TcP) phase, they consist of a small atomic radius of a dense layer, which is inlaid with a large atomic radius of atomic structure, this is a highly dense pile. In addition to atomic size factors, their formation is also influenced by the concentration of electrons.

Q:How much is one ton / ton of high alumina refractory brick?

The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012

Q:What refractory material does cupola lining use?

It's made of high quality refractory material: 1770 ~ 2000 centigrade.

Q:How much is one ton of high alumina refractory brick?

Three high aluminum refractory brick Zhengzhou Kuwait is generally around 800. 32 years of experience, good.

Q:Does the chimney have high acid resistance?

If it is an ordinary high alumina brick, it does not meet the requirements of acid resistance, and only the chimney lined with acid resistant bricks.

Q:What are the main components of high alumina bricks?

Sweat is like water mineral alumina bauxite, aluminum ore, magnesite, waves of gibbsite. Anhydrous alumina raw material, such as corundum, alumina, fused corundum. High alumina brick Zhengzhou gold company specializing in the production of various specifications, you can directly ask their technical staff.

Q:What are the specific raw materials for plastic pallets?

With excellent mechanical properties, its strength and elasticity are higher than HDPE, and it has good flexural fatigue resistance. It has good heat resistance and good chemical stability. Besides being concentrated by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents. The high frequency insulation performance of polypropylene is excellent because of its almost no water absorption, so the insulation performance is not affected by temperature.
