Q:What is the heat preservation material used in a laboratory furnace?
Asbestos, high alumina brick, or carbonized silicon are often used.Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.
Q:What are the specifications for 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.
Q:What is the difference between T3 refractory bricks or high alumina refractory bricks?
High aluminum refractory brick brick is all in one type of material classification, the material is AL2O3 high bauxite content above 55%, refractory brick by material into clay bricks, high aluminum brick brick brick corundum brick
Q:What is the price of the first grade high alumina brick?
Many factories in Xinmi have high alumina bricks, but they must choose a regular factory. Kuwait refractory level high aluminum brick price at around 1600, the quality of double stable supply
Q:What are the common thermal insulation materials for thermal conductivity?
The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.
Q:What's the weight of the refractory bricks?
According to shape and size can be divided into standard brick, ordinary brick, special brick, etc.. 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 refractory material does cupola lining use?
It's made of high quality refractory material: 1770 ~ 2000 centigrade.
Q:Which is faster for heat transfer between corundum bricks or high alumina bricks?
75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
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:Corundum, high alumina and fireclay refractory difference is what
In fact, they are not consistent with raw materials, corundum refractories can use white corundum, white corundum, brown corundum corundum material, alumina content of these materials is higher than 90%, while the high aluminum refractory material is bauxite, alumina in 90 to less than 70, and clay raw materials the aluminum content is less than 70..
