<tailings pump repairing> The application of Fujian molybdenum ore tailings pump pump case and pumping element wear resistant repair coatings:
Maintenance workpiece: tailings pump guard jacket repairing,tailings pump guard plate repairing.
Material: High chrome alloy.
The condition before repairing: perforation scrap part.
Material selection: BD7041 slurry pump anti abrasion corrosion resistant coatings,BD426T special undercoat (topcoat).
Construction tools: angle grinder,wire brush,grinding wheel,plaster knife,plastic knife,rubber hammer,special rounding tools,hair brush,electronic scale.
Auxiliary materials: cleaning agent,duster cloth,gloves.
Construction technology of BD7041 slurry pump anti chemical wear resistant coating:
1.Clean up and polish pending-repair workpiece on the needing-repair part.
2.Configure BD426T special undercoat and brush coating on the pending-repair part.
3.Configure BD7041 slurry pump anti impact abrasion resistant repair coatings 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.Configure BD426T special undercoat and brush coating on the workpiece surface of repairing part as the topcoat.
5.Curing for 24 hours.
Material utilization amount: 25Kg BD7041 slurry pump anti wear heat resistant protective coatings, 1.5Kg BD426T special undercoat.
