Premium Mortar for High-Temperature Bonding

Short Description:

Refractory mortar, also known as fire mortar or joint material (powder), used as bonding refractory products brickwork materials, according to the material can be divided into clay, high aluminum, silicon and magnesium refractory mortar, etc. It is called ordinary refractory mortar made of refractory clinker powder and plastic clay as binder and plastic agent. Its strength at room temperature is low, and the formation of ceramic bonding at high temperature has high strength.

Description

Refractory mortar is a joint material used to build shaped refractory products. It is composed of refractory powder, water or liquid binder and admixtures (such as dispersant plasticizer, stabilizer or water retention agent). A paste-like slurry (or thick suspension) containing a high concentration of solid particles, which has the characteristics of Bingham's fluid. The solid/liquid mass ratio is about (70~75)/(30~25) and the solid/liquid volume ratio varies with the specific gravity of the refractory powder, about (35~50)/(65~50 ). Generally, it is applied with a spatula.

 

Classification

Refractory mortar, also known as fire mortar or joint material (powder), used as bonding refractory products brickwork materials, according to the material can be divided into clay, high aluminum, silicon and magnesium refractory mortar, etc.

It is called ordinary refractory mortar made of refractory clinker powder and plastic clay as binder and plastic agent. Its strength at room temperature is low, and the formation of ceramic bonding at high temperature has high strength.

With hydraulicity, air hardening or thermo-hardening materials as binder, called chemical binding refractory mortar, as below the formation of ceramic binding temperature before the production of a certain chemical reaction and hardening. 

Features

Refractory mortar characteristics: good plasticity, convenient construction; high bond strength, strong corrosion resistance; high refractoriness, up to 1650℃±50℃; good slag invasion resistance; good thermal spalling property. 

Application

Refractory mortar is mainly used in coke oven, glass kiln, blast furnace, hot blast stove, metallurgy, architectural material industry, machinery, petrochemical, glass, boiler, electric power, iron and steel, cement and other industrial kiln.
