the guard jacket is wearing perforated.
The condition before repairing: almost scrapping.
BD7042 slurry pump epoxy repair compound super abrasion wear resistant coating,BD426T special undercoat.
Angle grinder,wire brush,grinding wheel,plaster knife,plastic knife,rubber hammer,special rounding tools,hair brush,
electronic scale,iodine-tungsten lamp.
Auxiliary materials: cleaning agent,duster cloth,gloves.
Construction technology of BD7042 super wear abrasion resistant slurry pump repair epoxy coatings:
1.Clean up and polish the pending-repair workpiece on the needing-repair part.
2.Configure BD426T special undercoat and brush coating on the pending-repair part,then wait for the primer curing.
3.Configure BD7042 super wear resistant coating and make it be coating on the pending-repair part,knock on it to be compacted
with rubber hammer,then trim the surface with special rounding tools,make the surface be flat and smooth.
4.After initial curing at room temperature,heat it up to the temperature of 100℃ slowly and keep this temperature for 2 hours,
cool it down slowly.
5.Coating on the topcoat
