Refractory Mortar Description
Refractory mortar is made into new type inorganic binder materials by choosing the same powder materials, adding inorganic binder, according to request of construction materials. There are four grades as below NT-1300,NT-1400,NT-1500,NT-1600, each material is divided into light weight and heavy weight, we can choose relevant refractory mortar according to different request of construction materials.
Properties of Refractory Mortar
- Good plasticity, easy to construct,
- High bonding strength and resistance to corrosion,
- High refractoriness, reaching up to 1650℃±50℃,
- Excellent performance on resistance to slag erosion,
- Good spalling resistance.
Advantages of Refractory Mortar
Firclay mortar to be a strong monolithic building, which is the necessary monolithic refractory for resisting high temperature erosion and adjust the difference of bricks shapes and sizes, and also can balance the expansion between firebricks. Thus only use high quality fireclay mortar that can prolong the service life of furnaces and kilns.
Manufacturing Process of Refractory Mortar
Fireclay mortar adopts hard clay grog as the base stock, and is combined with soft clay or chemical binding agents. Particle size of powdery material is decided according to the service demand. fire clay mortar limit particle size is general lower than 1mm, and some are lower than 0.5mm or lower. Rational grain composition guarantees the construction property, so are the binding agents and admixture. Refractory mortar is mainly used for jointing and repairing furnace body that is build with fireclay bricks in blast furnace, hot blast stove, coke oven, soaking pit furnace, heat exchanger and boiler.
