company news about Application of the refractory mortar

Refractory mortar is used as a refractory masonry joints unshaped refractory materials by a certain proportion of refractory particles of powder and binder, additives composed of water or liquid binder into a slurry. Refractory mortar binding agents according to their characteristics can be divided into the setting and hardening hydraulic, thermal rigid, rigid gas fire-resistant mortar. Refractory hydraulic cement slurry is binder, can be used at room temperature or may be in contact with water or moisture. Thermosetting refractory mortar commonly phosphoric acid or phosphate thermosetting binder made of hardened mud except this has a higher strength at various temperatures, there shrinkage, tight joints, corrosion resistance and strong features. Rigid gas fire-resistant mud rigid gas commonly used sodium silicate binder formulation that allows mud masonry joints tight.
