- Q:Is there a big difference between two high alumina brick and one high alumina brick?
- According to my experience, two kinds of high alumina bricks from the index, there is a big difference between the content of AL2O3, a high aluminum brick in 75%, two grade high alumina bricks in 65%, so the content is not the same, also decided that the use of temperature difference, the difference is very big.
- Q:What is the price of the latest thermal insulation material?
- There are many kinds of insulation materials, and the price will fluctuate with the market. Small quantities of inquiry or procurement, then go directly to the local thermal insulation market, a wide variety of prices are basically the market price.
- Q:What is the difference between fireclay bricks and high alumina refractory bricks?
- High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3.
- Q:How to test the aluminium bricks of high alumina refractory bricks?
- Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard
- 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?
- The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred.
- 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 does refractory consist of?
- According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
- 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: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.
