- Q: What are the high aluminum bricks made of?
- The amount of refractory mud accounts for about 6% of the brick weight
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- Refractory brick is non-metallic materials can be classified according to a kind of inorganic material, high aluminum brick, clay brick, magnesia brick, corundum brick, mullite bricks, silicon carbide materials such as brick, high alumina brick is used as a relatively wide range of products in accordance with the refractory brick high alumina refractory materials by high aluminum brick is generally divided into Al2O3 content three: I - II - >75% Al2O3 content; the content of Al2O3 is 60 ~ 75%; III - Al2O3 content from 48 to 60%.
- Q: The difference between aluminium refractory and magnesia refractory
- Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.
- Q: What is the content of free silica in the refractory bricks of high alumina bricks?
- Refractory powders are not rich in free silica in varying degrees
- 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 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: Is glass wool inorganic thermal insulation material?
- Yes, glass wool belongs to one kind of glass fiber. It is a kind of man-made inorganic fiber. Therefore, in the field of thermal insulation materials classified as inorganic insulation materials.
- Q: Does the chimney have high acid resistance?
- The acid resistant bricks used for chimney are usually made of custom-made trapezoidal acid proof bricks, and the physical and chemical indexes of acid resistant bricks need to be confirmed according to the chimney's actual emission. At this point, you can consult our kerei refractories.
- Q: How does the physicochemical index change when the high alumina brick is used at high temperature?
- When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.
- Q: What should be used as binder for making high alumina bricks?
- In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.
