Product overview:

It is made of sintered or electrofused magnesite or synthetic magnesia powder, which is mixed with binder and additive in proportion. The Magnesia refractory mortar is mainly used as the joint material for laying magnesia bricks.

According to MgO content, magnesia refractory mortar can be divided into three brands: MN-91, MN-95 and MN-97. Magnesia-aluminum refractory mortar can be divided into two brands according to MgO content: MLN-70 and MLN-80. According to the content of Cr2O3, Magnesia-chrome refractory mortar can be classified into four brands: MGN-8, MGN-12, MGN-16, and MGN-20.

The M, L, G and N respectively represent the first letter of magnesium, aluminum, chromium and mortar in Chinese pinyin, followed by the numbers respectively represent the mass fraction of MgO and Cr2O3.

Character:

1. Good plasticity and convenient construction;

2. High bond strength, strong corrosion resistance;

3. High refractoriness, up to 1650℃±50℃;

4. Good slag penetration resistance;

5. Good anti- spalling under high temperature.
