Q:What's the use of refractory bricks?
Refractory bricks are mostly used in the lining of furnaces of high temperature industries. Such as iron and steel industry, blast furnace, hot blast furnace, converter, colored reverberatory furnace, rotary kiln, etc.
Q:What are the main constituents of refractory bricks?
Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon aluminum
Q:How can the silica in zircon sand be removed during the smelting of zirconium corundum?
Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.
Q:What's the weight of the refractory bricks?
Referred to as refractory brick. Refractory made from refractory clay or other refractory material. 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:What is the face brick
According to the shape and size can be divided into ordinary brick, standard brick, etc. can be used as a specific type of building furnace and various thermal equipment of high temperature building materials and structural materials, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action.
Q:Zirconium corundum 25 content and 40 content, how to distinguish in appearance?
It is in the production process, zirconium corundum bricks are likely to cause pollution.
Q:Outside wall tile (whole body smooth surface has small hole split brick) has cement pollution, with what product cleaning (cement, mortar, cleaning agent)?
Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.
Q:What are the specifications for bricks?
Thecompressive node as a new type of building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, improve work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, it has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process
Q:What is brick power, half brick power and full brick power difference?
Power module. Small size, high power. General use should order additional storage energy, heat dissipation, etc.. Dimensions such as brick, so called brick power supply. Half brick power supply is half the size of all brick power supply.
Q:What are the categories of bricks?
Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.
