Fire clay or as a refractory mortar joint sealant (powder).QiFeng materials used as refractory brick masonry.According to the material can be divided into the clayey, high aluminum, silica and magnesia refractory mortar and so on.Consist of refractory powder, binder and additive.

Almost all of the refractory raw material can be made to make powder used in the refractory mortar.Add right amount for the refractory clinker powder plastic clay as binder and plasticizer and said common refractory mortar, the normal temperature strength is low,

high temperature ceramic combination with high strength.Water hardness, gas rigid or hard combined with material as binder said chemical combination of refractory clay, before the temperature below into ceramic combined produce certain chemical reactions and hardening.

Choose the material of refractory slurry, consideration should be given in accordance with the material of masonry of refractory products.Refractory mortar except for QiFeng material, also can use the smudge or injection method is used as the lining body protection coating.
Refractory mortar characteristics and application:
1, plasticity is good, construction is convenient;2, bonding strength, strong corrosion resistance;3, high refractoriness, up to 1650 ℃ + 50 ℃;4, resistance to slag
Good abuse;5, good thermal spalling.Refractory mortar is mainly used in coke oven, glass furnace, blast furnace hot blast stove, and other industrial kiln.Application of the industry
Are: metallurgy, building materials, machinery, petrochemical, glass, boiler, electric power, steel, cement, etc.
