The description of BD7042 slurry pump high temperature wear abrasion corrosion resistant epoxy paste coating:
performance feature of our BD7042 slurry pump pipeline abrasion wear corrosion resistant repair coatings:
1.Two-component,small particles,based on epoxy resin main raw material
2.Excellent in wear & corrosion resistance.
3.With very high bonding strength to metal substrates
4.Convenient for construction,without very high technical requirements for constructors.
5.Suitable for the repairing and protecting of various wear,corrosion working condition
product usage of our BD7042 slurry pump pipes high temperature chemical wear corrosion resistant epoxy coating:
BD7042 slurry pump repairing small particle ceramic beads filled epoxy wear abrasion corrosion resistant coating is the high performance
wear&corrosion resistant material compounded by high performance wear resistant material and modified toughening resin.
Used in the heavy medium erosive wear repairing and pre-protecting of slurry pump,swirler,classifier,jet flowing machine,grit mouth,
slurry blender,conveyer pipeline elbow etc.
How to use of our BD7042 slurry pump repairing abrasion corrosion resistant ceramic beads filled epoxy coatings:
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 or volume ratio 3:1, 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 1Kg,
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 suitable coating thickness of BD7042 slurry pump chemical wear corrosion resistant ceramic particle filling 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 fully infiltrates with the substrates,repair the surface to be smooth after the coating is coated
on the suitable size,if it has high surface requirements,can make the BD426 corrosion resistant repair agent 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 putting into use,(If can heat it up to the temperature of 60-80 degree
and keep this temperature for 2 hours,in this way,can improve 30% comprehensive performance) If the temperature is below 5 degree,
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.
