product usage of BD727 anti corrosive abrasion resistant coatings:
BD727 high temperature wear & corrosion resistant coatings is the high performance high temperature resistant,wear&corrosion resistant polymerization ceramic material compounded by high performance wear resistant,corrosion resistant material(such as ceramic,silicon carbide,carborundum,titanium alloy etc.) and modified toughening heat resistant resin.Used in repairing the erosive wear workpiece and preparation of wear resistant coatings under high temperature working condition.Such as the wear resistant protection of suffering from scour parts based on cement vertical mill
How to use of BD727 anti wear high temperature resistant 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 4:1, make A and B two components mix uniformly,and use it up within 40 min.Generally it’s while construction and configuration.Every time the most configuration quantity is not more than 2Kg,too much adhesive is solidified too fast,hasn’t been used up until the adhesive has partial solidified and can’t be used.According to the actual temperature,distribution can be properly a little more in winter and 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 coating thickness of BD727 high temperature wear & corrosion resistant coatings is 2-8mm,make the mixed-up material be coating on the pending-repair part layer by layer,the first layer should be compacted,make it fully infiltrates with the substrates,repair the surface to be smooth after the coating is coated on the suitable size,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 25℃ before putting into use,if the temperature is low,should heat it up or prolong curing time to promote the curing.General construction in winter,you can use iodine tungsten lamp do irradiation heating with 40cm distance from the coating.
