Refractory Mortar

Refractory Mortar

Short Description:

Refractory mortar consists of refractory powder, binder and admixture. Almost all refractory raw materials can be made into powder used to prepare refractory mortar. The ordinary refractory clay made by adding refractory clinker powder and an appropriate amount of plastic clay as a binder and plasticizer is called ordinary refractory clay, which has low strength at room temperature, and high strength is formed by ceramic bonding at high temperatures. The chemically bonded refractory clay, which uses hydraulic, air-hardened or thermosetting bonding materials as the bonding agent, produces a certain chemical reaction and hardens before it is lower than the ceramic bonding temperature.

Description

Refractory mortar consists of refractory powder, binder and admixture. Almost all refractory raw materials can be made into powder used to prepare refractory mortar. The ordinary refractory clay made by adding refractory clinker powder and an appropriate amount of plastic clay as a binder and plasticizer is called ordinary refractory clay, which has low strength at room temperature, and high strength is formed by ceramic bonding at high temperatures. The chemically bonded refractory clay, which uses hydraulic, air-hardened or thermosetting bonding materials as the bonding agent, produces a certain chemical reaction and hardens before it is lower than the ceramic bonding temperature.

The particle size of refractory mortar varies according to the requirements of use, and its limit particle size is generally less than 1mm, and some are less than 0.5mm or finer.

The material of refractory mortar should be considered consistent with the material of refractory products of masonry. In addition to being used as a jointing material, refractory mortar can also be used as a protective coating for the lining by painting or spraying.

Features

Good plasticity and convenient construction / High bonding strength, strong corrosion resistance

High refractoriness, up to 1650℃±50℃ / Good slag resistance / Heat exfoliation

Application

Refractory mortar is mainly used in coke ovens, glass furnaces, blast furnace hot blast furnaces, and other industrial furnaces. The applied industries are: metallurgy, building materials, machinery, petrochemicals, glass, boilers, electric power, steel, cement, etc.
