slurry pump repair anti wear abrasion corrosion resistant coating

high temperature anti chemical impact corrosion wear abrasion resistant epoxy coatings used in Tongbai Yingdongpo gold mine slurry pump guard plate pipeline ceramic rubber liner repairing and protecting

Maintenance workpiece: slurry pump guard jacket,wear scrapped slurry pump guard plate pipeline ceramic rubber liner

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:
BD7021 slurry pump repair epoxy compound super abrasion 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 of BD7021 anti wear abrasion resistant slurry pump epoxy repair coating:
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 BD7021 super wear abrasion resistant slurry pump repair epoxy 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:BD7021 slurry pump repair super anti abrasion resistant epoxy 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 BD7021 super wear resistant coatings, 1Kg BD426T special undercoat.

Range of application for our BD7021 slurry pump repair anti wear abrasion corrosion resistant coating:
Used in the repairing and pre-protecting of slurry pump,centrifuge,cyclone,chute,classifier,jet machine,flotation machine,grit mouth,
slurry mixer and the transporting pipe elbow of heavy medium erosive wear.
