‘‘‘‘BD7031 wear abrasion corrosion resistant repair compound high alumina ceramic epoxy coatings
used in aluminium industry alumina factory slurry pump guard plate and guard jacket repairing and protecting
Maintenance workpiece:scrapped slurry pump guard jacket,guard plate and impeller rubber ceramic lining
Material: High chrome alloy.
Working condition description:
the temperature of slurry material is much higher,both has certain corrosivity,and the concentration is much higher,abrasion is serious,
and has cavitation erosion phenomenon.
Material selection:
BD7031 alumina factory slurry pump repair epoxy compound super wear abrasion resistant coating(high temperature resistant,
corrosion resistant,cavitation erosion resistant,abrasion resistant),BD426T special undercoat(enhance the material and
substrates bonding force)
Construction tools:
angle grinder,wire brush,plaster knife,plastic knife,rubber hammer,special rounding tools,hair brush,electronic scale.
Auxiliary materials: cleaning agent,duster cloth,gloves.
Construction technology of BD7031 alumina plant slurry pump abrasion wear resistant repair epoxy coatings:
1.Clean up and polish pending-repair workpiece on the needing-repair part
(First clean up the residual impurity on the pump part,then do the sand blasting treatment on the maintenance area,
if it doesn't have the sand blasting condition,can polish it with angle grinder,clean it by cleaning agent and dry it by airing).
2.Configure the BD426T special undercoat and brush coating on the pending-repair part.
(When the temperature is low,can preheat the prime coat and metal substrates first,then brush a shin layer of prime coat coating
on the substrate).
3.Configure BD7031 alumina plant slurry pump repair epoxy super abrasion 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.Curing for 24 hours,when the temperature is low,should take heating measures to promote the curing.
Material utilization amount:
21Kg BD7031 super anti abrasion wear resistant epoxy alumina factory slurry pump protective coatings,
0.5Kg BD426T special undercoat.
Using effect:
the service life of this new pump is about 3 months,the service life after repairing can reach to the new pump service life,
get the customers' high praise.
