Вогнетрывалы раствор

Refractory mortar is made into new types of inorganic binder materials by choosing the same powder materials and adding inorganic binder, according to the request of construction materials. There are four grades below NT-1300, NT-1400, NT-1500, and NT-1600, each material is divided into lightweight and heavyweight, and we can choose relevant refractory mortar according to different requests for construction materials.

Application of refractory mortar

Application industries include metallurgy, building materials, machinery, petrochemicals, шкло, катлы, electric power, steel, цэмент, г.д. The material of refractory mortar shall be consistent with that of masonry refractory products. In addition to being used as a pointing material, refractory mud can also be used as a protective layer for linings by coating or spraying.

Construction process of refractory mortar

1. Basic cleaning. First of all, it is necessary to clean the surface of the foundation to avoid debris such as floating dust and oil.
2. Wet construction surface. Before application, use a roller or sprinkler to wet the surface, but there should be no excess water during application.
3. Configure materials. Mix mortar and water, and add water at 14-20%, depending on the actual situation.
4. Smooth the surface. The stirred mortar is poured on the operation plane, which needs to be completed within 20 minutes.
5. Maintenance. Sprinkle water after repair, or cover with plastic film for maintenance.
