Refractory mud is unfamiliar to most people. It is composed of refractory powder, binder and admixture. The material of refractory slurry should be consistent with that of refractory products of masonry. In addition to being used as joint material, fireclay can also be used as protective coating for lining by coating or spraying. Do you know how to use fireclay? Let's follow Xiaobian and have a look
Use method of refractory mud:
1. First, the furnace is cleaned up. First, the furnace is hung with fire-resistant cement or aluminate cement for one or two times. After drying, the refractory cement and refractory sand are adjusted according to the ratio of 1:1. Part of the furnace is partially filled in the furnace. Then, the small rubber hammer is used to gently tamp the furnace. After the whole furnace is compacted and replenished, the refractory cement is hung once or twice and dried in the shade for about a week, There are no cracks in the furnace!
2. It is composed of refractory powder, binder and admixture. Almost all refractory materials can be made into powder used for preparing refractory mud. The ordinary refractory mud, which is made of refractory clinker powder and proper amount of plastic clay as binder and plasticizer, has low strength at room temperature, and has high strength only when ceramic bond is formed at high temperature. The chemical bonded refractory mud, which uses hydraulic, pneumatic or thermal binding materials as binder, will produce certain chemical reaction and harden before it is lower than the bonding temperature of ceramic.
3. The particle size of refractory mud varies according to the use requirements, and its particle size is generally less than 1 mm, some less than 0.5 mm or finer.
4. The material of refractory slurry should be consistent with that of refractory products of masonry. Fireclay used as joint material
In addition, the coating method or spray method can be used as the protective coating of the lining body.
