Wear - Resistant Plastic Castable Refractory Dense 90% Al2O3 refractory plastic For CFB Boiler
High-strength wear-resistant plastic refers to corundum, mullite or silicon carbide and other high-grade refractory materials as the main raw material, added with binder and additive by mixing, extrusion into adobe shape which still has good plasticity, and can be used tamping method construction after packaging stored after a certain period of time.
High strength wear-resistant plastic can be semi-wet clay, water or aluminum dihydrogen phosphate or other liquids mixed into mud during construction, press or extrusion into a certain plasticity block. Tamping with a tamper will result in plastic deformation but no cracking or collapse. The deformed shape can be maintained after the external force is removed.
High strength wear-resistant plastic Features:
1. Good plastic construction, no bulge, no cracking.
2. Excellent wear resistance;
3. The construction time can be adjusted, and the construction time can be maintained for a long time at high temperature;
4. Excellent corrosion resistance
5. Long shelf life, convenient construction
6. High temperature resistance and high operating temperature.
7. After strong tamping, the volume density is dense and the anti-slag permeability is strong.
8. Convenient construction, short maintenance time and quick recovery of production.
High strength wear-resistant plastic Application:
High strength wear-resistant plastic can be applied to wear resistant and scour resistant parts of various boilers, such as circulating fluidized bed boiler cyclone, lining of furnace wall, ash impact and serious parts. The use of this material in maintenance or emergency repair can reduce oven time and restore capacity as soon as possible. Widely used in electric power, metallurgy, steel, ceramics, chemical industry and other industries.
High strength wear-resistant plastic producted by us can be used for the repair of inner liner of circulating fluidized bed boiler or integral masonry of some parts.
