Product Introduction

Description

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

Features

Refractory mortar has many features, such as good plasticity and convenient construction , high bonding strength, strong corrosion resistance, high refractoriness, up to 1650℃±50℃ and so on.

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.
