Wear-resistant Refractory Mortar and Masonry Materials Series Products

Refractory clay, referred to as refractory clay or refractory clay, is composed of refractory powder, binder and admixture. Almost all refractory raw materials can be made into powders used to prepare refractory mud.

Ordinary refractory clay, which is made from refractory clinker powder and an appropriate amount of plastic clay as a binder and plasticizer, has low strength at room temperature. Only when it forms a ceramic bond at high temperatures does it have higher strength. Chemically bonded refractory mud, which uses hydraulic, gas-hardening or thermo-hardening bonding materials as binding agents, hardens through a certain chemical reaction before the temperature is lower than the temperature at which ceramic bonding occurs.

 

The function of refractory mud is to fill the joints of refractory bricks when we build furnaces to bond each other and make the masonry have a certain integrity, strength and air tightness. Therefore, the use of refractory mud has an impact on the quality of the masonry, the heat loss of the electric furnace and the furnace Shell temperature has a significant effect.

When we use refractory mud, we need to have the following requirements for the selected refractory mud:

1. After combining with water, the refractory mud can be mixed to a suitable volume consistency to fill the uneven parts left by the refractory bricks without cracking;

2. Any refractory raw material can be made into refractory mud, but when using refractory mud, we must match it according to the brick properties of the relevant refractory brick masonry, from material to refractoriness, load softening temperature, etc.;

3. Refractory mud must have good airtightness after drying and use at high temperature;

4. It has a certain mechanical strength and can withstand the pressure of the kiln operating environment.

This series of products is developed by ourselves according to the design conditions and operating conditions of various furnaces. It uses alkaline or alkaline mortar. The product is made of corundum fine powder, high-quality high-alumina vanadium fine powder and other additives. It is mainly used for masonry and bonding construction of high-strength wear-resistant bricks, PA bricks, cast fired bricks, clay bricks, high-alumina bricks, phosphate bricks, insulation bricks, and insulation materials. The main features of this product are: high bonding strength, small high-temperature shrinkage, good fluidity, and easy use.
