High temperature anti impact wear abrasion resistant repair compound epoxy coatings
used in dredger silt pump guard plate and guard jacket repairing and protecting
The impeller diameter of Luji Ningjun 41 dredger slime pump is 1m,the weight of guard jacket is 2 tons,
this pump is mainly used in pumping the sludge of lakebed and turning lakes into fields,guard jacket,
guard plate and impeller are badly abrasion,the original conveying distance is 1.2Km,the conveying distance
is only 700m before stopping maintenance,even the rate of flow reduces about 1/3.

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,
when the temperature is low,can heat it up to promote the primer curing,the construction time of this pump is on 3rd,
January,the temperature is below zero,should heat it up to promote the curing through oxygen welding baking the back
side after brush coating the primer.
3.Configure BD7021 slurry pump pipeline epoxy repair compound super abrasion resistant coatings and
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 to be flat and smooth.
4.Curing for 24 hours,the curing of BD7021 slurry pump pipeline repair compound abrasion wear impact resistant epoxy coating doesn't
have a high temperature requirement,even through the temperature is zero,it can still be normal curing.
Material utilization amount:
50Kg BD7021 super wear resistant slurry pump repair epoxy coatings,
2Kg BD426T special undercoat.
The expected working life of this pump after maintenance is about 2.5 to 3 years.

used in Zhengzhou Yuzhong energy slurry recycle pump guard plate and impeller
erosive wear corrosion repairing
Zhengzhou Yuzhong energy 6 pieces slurry circulating pumps entrance front guard plate and impeller cooperate with parts have serious abrasion,
it affects the rate of flow,use the BD772 carbide silicone anti wear abrasion resistant repair epoxy coating from our company
(Xiangyang City Hundred Shield Coating Material Co.,Ltd) to do the repairing,the construction period is 1 day.
BD772 wear abrasion resistant epoxy repair compound carbide silicone coating has high bonding force,abrasion resistant and impact resistant,
can solve the slurry erosive wear and corrosion effectively.

BD772 slurry circulating pump wear abrasion resistant repair silicone carbide coating:
BD772 silicon carbide coating is the high performance wear resistant,corrosion resistant polymeric material which compounded
by the high performance abrasion resistant,anti corrosive materials--highest crystallizing silicone carbide and modified toughening
hybrid resin.Mainly used in the wear repairing and pre-protecting of slurry circulating pump impeller,body case,slurry stirring paddle etc.
1.With excellent wear & corrosion resistance,suitable for the protection of abrasion,corrosion working condition
2.With very high bonding strength to metal substrates
3.Don’t drip and slip,the construction is convenient
4.Don’t precipitate,don’t separated layer
5.water resistant,acid resistant,alkali resistant
6.Can do the machining
7.The prominent advantage of BD772 carbide silicone coating is its machinability,for the workpiece which has accuracy requirement,
it can do the accurate repairing
