anti wear abrasion chemical resistant slurry pump repair epoxy coating

The application of our anti abrasion chemical resistant coatings use in slurry pump guard jacket wear resistant repairing:

<Slurry pump repairing> Tongbai Yingdongpo gold mine Co.,Ltd tailings slurry pump guard plate and guard jacket wear resistant repair
Maintenance workpiece: slurry pump guard jacket repairing,wear scrapped slurry pump guard plate repairing
Material: High chrome alloy.
The condition before repairing:perforation scrap part,the guard jacket has already been worn through,the guard plate is severe wear,the part of feed port is serious missing.
The repairing difficulties:There is no sealing ring between guard plate and guard jacket of this pump,it depends on taper for sealing completely,the accuracy requirement is very high.
Material selection: BD7024 super wear resistant coating,BD426T special undercoat.
Construction tools: angle grinder,wire brush,grinding wheel,plaster knife,plastic knife,rubber hammer,special rounding tools,hair brush,electronic scale,drying oven.
Auxiliary materials: cleaning agent,duster cloth,gloves.
Construction technology:
1.Clean up and polish the pending-repair workpiece on the needing-repair part,clean it by cleaning agent and dry it by the airing.
2.Weigh A and B component of BD426T special undercoat according to the specified ratio and mix them uniformly,and brush coating on the pending-repair part,then wait for the primer curing,when the temperature is low,can heat it up to promote the primer curing.
3.Weigh the BD7024 super wear resistant coating according to the specified ratio and mix it uniformly,make the mixture uniform materials be coating on the pending-repair part,knock on it to be compacted with rubber hammer,repair the surface of adhesive layers to be smooth with special rounding tools,make the surface to be flat and smooth.
4.Curing:BD7024 super abrasion resistant coating can be initial curing at room temperature,after initial curing,heat it up to the temperature of 100℃ slowly and keep this temperature for 2-3 hours,only in this way,it can improve 40% combination property.Generally it can exceed the working life of new pump.
Material utilization amount: 12Kg BD7024 super wear resistant coatings, 1Kg BD426T special undercoat.
