Excellent thermal shock resistance, abrasive resistance and high temperature toughness; good mechanical strength in various temperature; well-proportioned and stable
quality, difficult to cluster and long shelf life.
Powder feature:
It has the high bonding strength after mixing with refractory aggregate, hardener etc. at room temperature for 4 to 24 hours under 90-110℃; then, dry it at 350-500℃,high fracture resistance, compression resistance and hydration resistance. It can not
soften although soaking and boiling.
Application:
Electrical industry, high temperature furnace, heat treatment resistance furnace, ceramic building, electrical insulation; refractory bonding agent in high temperature furnace.
Powder: refractory gunning material, cement, castable, ramming material and phosphate brick.
