Product Description

High Quantity Mullite Refractory Mortar Jointing Material
The Description:
Refractory mud is the joint material used in the masonry of refractory products, that is, the refractory mud used in the lining of common refractory bricks in furnaces, also known as joint material, mortar, etc. Refractory mud is a combination of refractory powder, binder and additive, which is applied on the surface of refractory brick.

 

According to the material, the refractory mud is divided into: clay, high aluminum, mullite, siliceous aluminum silicate mud, magnesium, magnesium carbon and other alkaline mud, carbonaceous cement and other refractory mud.

 

Different materials of refractory mud and masonry refractory brick materials are also different, and the use temperature is also different.

 

(1) Clay bricks use refractory mud for clay refractory mortar;

 

(2) The use of high alumina brick refractory mud for high alumina refractory mud;

 

(3) Mullite bricks use refractory mud for mullite refractory mud or corundum refractory mud;

 

(4) The use of silica brick refractory mud for siliceous refractory mud;

 

(5) magnesia brick using refractory mud for magnesia refractory mud;

 

(6) Magnesia carbon brick using refractory mud for magnesia carbon refractory mud;

 

(7) The refractory mud used in light firebricks is matched with thermal insulation refractory mud of the same material;

 

The main refractory materials of aluminum silicate refractory mud are different grades and different contents of aluminum oxide powder, adding other powders, binders and additives; Magnesia is the main refractory material of magnesia refractory mud. The refractory materials used in carbon-based refractory mud are fixed carbon, etc., and then other powders and bonding agents are added. The selection of different materials for the production of refractory mud is different, the formula is different, and the firebrick used with masonry is also different.
