Silicate fireproof heat-resistant concrete with Portland slag cement, Portland cement and water glass as cementing material, broken clay brick, clay, cement clinker, broken high alumina brick as aggregate.
- Q: How many cubic bricks does a high alumina brick have?
- It is related to the content of aluminum in high alumina bricks.
- Q: What is the density of a super high alumina brick and what is the price?
- Of course, the transaction price, please choose refractory brick manufacturer is better.
- Q: How to make refractory bricks and boiler wall adhesion more firm?
- If the condition, the user heat-resistant steel welding grip nails, expansion joints can not be too big.. Also to use high temperature aluminum brick, high temperature resistance, but also to extend its use cycle.
- Q: What are the specifications for bricks?
- In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..
- Q: The difference between ordinary and diatomite brick refractory brick
- Refractory brick belongs to a large class, according to different materials used are divided into: high alumina brick, dolomite brick, magnesia chrome brick, magnesia spinel brick, phosphate brick, carborundum brick, brick, mullite bricks etc..
- Q: How high can aluminum bricks expand at 80O degrees of heat?
- When an object is heated, the particle moves faster and thus occupies additional space. This phenomenon is called dilation.
- 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: The difference between clay bricks and clay bricks
