Product Introduction
Plastic refractory is an unshaped material in the form of hard mud paste, which is made up of granular and powdery materials, combined with plastic clay and other binders and plasticizers, added with a small amount of water, and fully mixed. This material can maintain high plasticity for a long time.
Features
1.Easy construction. 2.Good plasticity. 3.Excellent wear resistance. 4.Low thermal conductivity. 5.Good thermal insulation. 6.Good thermal shock resistance.
Application
It is widely used in the insulation parts of industrial kilns and thermal equipment in metallurgy,heat treatment furnace,Furnace of incineration of garbage, recirculating fluidized bed furnace、petroleum industry, chemical industry and other industries.
