Packing specification:
Two component,20Kg/group,packed in a drum
performance feature of BD7012 slurry pump wear resistant protective coatings:
small particles,heat for curing
Excellent in wear & corrosion resistance
BD7012 slurry pump abrasion resistant protective coating and metal substrate has a high bonding strength
Convenient for construction,without very high technical requirements for constructors,but need heating equipment
Suitable for the repairing and protecting of heavy medium wear erosive working condition
product usage of BD7012 slurry pump special repairing coating:
BD7012 slurry pump abrasion resistant protective coating is the high performance wear&corrosion resistant material compounded by high performance wear resistant material and modified toughening resin.Widely used in repairing various heavy medium wear-out part and preparation of wear resistant coatings on the surface of various machine part which has wear resistant,corrosion resistant requirements. Such as repairing mine slurry pump,swirler,grit mouth,jet flow machine,classifier,feed delivery pipe and other equipment parts
How to use:
1. Surface treatment:Do coarsening treatment on the pending-repair part, grinding with angle grinder or sand blasting etc, the surface after coarsening treatment should be cleaned,the surface after this treatment should be the one coarsening,dry and fresh substrates,should be no greasy dirt and dust.(Then make the undercoat BD426T mix uniformly according to the specified ratio,and scrape coating on the surface of metal substrates,in guarantee under the premise of no shortage of adhesive,the adhesive layers are the thinner the better,then wait for the undercoat initial curing.This step is optional,can improve the bonding strength between the wear resistant layers and substrates.)
2. Configuration: Should heat the B component up to 50℃ first(also need heating the A component properly in winter),make A and B two components mix uniformly according to weight ratio 4:1,generally it’s while construction and configuration,don't configure too much adhesive every time,too much adhesive is not easy to mix uniformly.(When the temperature is low,the viscosity of 7011 is high,not suitable to mix uniformly,need heating up the A,B component separately first,then make them mix uniformly)
3. Coating: The suitable coating thickness of BD7012 slurry pump abrasion resistant protective coating is 8~30mm,make the proportioned adhesive blade coating on the metal substrates repeatedly,make the base material wet up the substrates,then make the mixed-up material press coating on the pending-repair part.After the coating is coated on the required size, blade coating towards a single direction to make the surface be smooth,should pay attention to controlling the coating thickness during repairing,in order to avoid appearing interference phenomenon in the assembly.
4. Curing condition: Heat up to 80℃ slowly and keep this temperature for 2 hours,and it can full cure for heating up to 120℃ and keeping this temperature for 2 hours
