Wear-resistant, fire-resistant and plastic | 50 |
Product Description:
Refractory and wear-resistant plastics are refractory materials prepared from 70% to 80% of granular and powdery materials, 10% to 25% of plastic clay and other binders, and an appropriate amount of plasticizer.Wear-resistant and refractory plastics are special refractory plastics that are made of corundum, mullite or silicon carbide and other refractory materials as their main raw materials, and have excellent wear resistance at operating temperatures.
Product Features:
The refractory plastic has high strength, good abrasion resistance, excellent corrosion resistance, long shelf life, and convenient construction and oven.It is suitable for the anti-wear lining of various CFB boilers. The use of this material in the maintenance can shorten the oven time.The plastic can be made into flakes and blocks.Certain bonding agents can also be added during construction.When in use, the mixture is compacted or rammed, and a dense lining and structure can be formed after baking.Good plasticity before hardening; certain strength after hardening.It has good sinterability, certain volume stability and other high temperature properties at high temperature.It is in the form of hard clay paste, and maintains high plasticity for a long time. It contains more plastic clay components, and has more water than ramming materials.It is mainly used in various heating furnaces that do not directly contact the molten material. The materials are mostly clay and high aluminum, but also silicon, magnesia, chromium, zircon and silicon carbide.
Product Usage:
It is suitable for the refractory and heat-insulating lining of petrochemical tube furnaces, as well as the refractory and heat-insulating lining of various heating furnace bottoms, furnace walls, flue chimneys, radiation chambers, convection chambers, elbow boxes, etc., and cracking of ethylene cracking devices Furnace lining.At the same time, it can also be applied to the heat insulation layer of other high-temperature kilns.
