Leaf wax powder

The pyrophyllite has the characteristics of low aluminum and high silicon, and can be used to produce alkali resistant brick. At the same time, as pyrophyllite can be used to produce ladle lining material, firstly, pyrophyllite has less expansion after heating, which is beneficial to improve the integrity of the masonry and reduce the erosion effect of slag on the brick joints; The second is that after the slag and the brick surface contact, the silicate melt with a large viscosity of 1 ~ 2mm can be formed, which hinders the penetration of the slag into the brick, thus improving the anti-slag erosion ability of the products.

When pyrophyllite is used as raw material, the characteristics of pyrophyllite should be determined according to the characteristics of raw materials. In pyrophyllite, the expansion by heat is small, contains the structure water less, the dehydration weight loss is only 5% ~ 6%, and the dehydration process is slow, the dehydration still maintains the original crystalline structure, so it can be directly used raw materials to make bricks, in order to reduce the production cost, but also can use mineral powder. However, when raw materials are used to make bricks, the volume expansion caused by pyrophyllite dehydration and quartz polycrystalline transformation will make the products loose and reduce the strength, so part of the raw materials calcined mature materials can also be added to the ingredients.

Because pyrophyllite has a small expansion characteristics, the products can not be burned, but also according to the use of requirements, the production of burned products.
