High alumina refractory mud

High alumina refractory mud, also known as high-temperature refractory mud, refractory cement, refractory mud, high alumina refractory mud, refractory mud, fireproof mud, can be divided into clay refractory mud, siliceous refractory mud, magnesium refractory mud, etc. according to the material.

High alumina refractory clay is composed of refractory powder, binder, and additives. Almost all refractory materials can be made into powder for preparing refractory mortar. Ordinary refractory clay is made by adding a suitable amount of refractory clinker powder and plastic clay as binders and plasticizers. Its strength at room temperature is low, and it only has high strength when it forms a ceramic bond at high temperatures. Chemical bonding refractory mud, which uses hydraulic, pneumatic, or thermosetting bonding materials such as water glass as a binder, undergoes a certain chemical reaction and hardens before reaching a temperature lower than the formation temperature of ceramics.

The particle size of refractory mud varies according to usage requirements, with the ultimate particle size generally less than 1mm, and some less than 0.5mm or finer.

The selection of refractory slurry material should consider consistency with the refractory products of the masonry. In addition to being used as a joint material, refractory mortar can also be applied or sprayed as a protective coating for the lining.

Advantages of high alumina refractory mud

1. Good plasticity and convenient construction;

2. High bonding strength and strong corrosion resistance;

3. High refractoriness, up to 1650 ℃± 50 ℃;

4. Good resistance to slag invasion;

5. Good thermal peeling performance. Refractory clay is mainly used in heat treatment industrial furnaces, resistance furnaces, gas furnaces, kilns, blast furnace hot blast stoves, and other industrial kilns.
