performance features of our BD228 pipeline centrifuge chemical wear abrasion resistant repair epoxy coating:
1.Two component,the performance is the same as BD218,gray paste.
2.With very high bonding strength to metal substrates
3.Don’t flow,with good formability,fast curing speed and good operation manufacturability
4.Suitable for the repairing and protecting of various wear,corrosion working condition.
product usage of our BD228 centrifuge pipeline abrasion wear impact resistant epoxy compound paste coatings:
BD228 centrifuge pipeline repair special heat impact wear abrasion resistant epoxy coating is the high performance wear & corrosion
resistant polymerization ceramic material compounded by high performance wear resistant ceramic particle and modified toughening
heat resistant resin.Widely used in repairing various wear-out parts and the preparation of wear & corrosion resistant coating on the
surface of various machine parts which have wear resistant,corrosion resistant requirements.The repairing and pre-protecting of medium
load coarse particle erosive wear chute,swirler,centrifuge,vibrating screen,pump body,fan shell,pipeline elbow,pipeline spiral conveyor etc.
How to use of our BD228 pipeline centrifuge heat impact abrasion wear resistant paste epoxy coating:
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.
2.Preparation:According to weight ratio 3:1 or volume ratio 2.8:1,make A and B two components mix uniformly,
and use it up within 30 min.Generally it’s while construction and configuration.Every time the most configuration quantity is not
more than 1.5Kg,too much adhesive is solidified too fast,hasn’t been used up until partial adhesive has solidified and
can’t be used.According to the actual temperature,configuration can be properly a little more in winter,
proper less in summer.If the temperature is too low,can properly heat up the A component to reduce viscosity for easy to configure.
3.Coating:The suitable coating thickness of BD228 pipeline centrifuge heat impact abrasion wear resistant paste epoxy coating is 4-8mm,
the most thickness can be 30mm.Make the mixed-up material be coating on the pending-repair part layer by layer,
the first layer should be compacted,make it infiltrates fully with the substrates.Repair the surface to be smooth after the coating is coated
in the suitable size.If the surface has high requirements,can make BD426 corrosion resistant coating adhesive be coating on the surface
as the topcoat,this material can’t do machining,should pay attention to controlling the coating thickness to avoid appearing interference
phenomenon in the assembly.
4.Curing:Cure for 24 hours at the temperature of 25 degree before using,if the temperature is low,should heat it up or prolong
curing time to promote the curing.General construction in winter,can use iodine tungsten lamp do irradiation heating with 40cm
distance from the coating.
