Construction technology:
1.Surface treatment:do coarsening treatment for clarified water pump pending-repair parts,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.Make the BD4261 pump repair special abrasion resistant prime coat mix uniformly according to the specified weight ratio and brush coating on the
metal substrates surface.
3.Preparation:Make the A and B two components of BD7045 slurry pump wearing resistant repair compound epoxy coating mix uniformly according to
the specified ratio,then use it up within 30 min.Generally while it’s construction and configuring adhesives,every time the largest configuring quantity
should not be more than 4Kg,too much adhesive is solidified too fast,hasn’t been used up until partial adhesive has been solidified and can’t be used.
If the temperature is low,you can properly heat up the A component to reduce the viscosity for easy to configure.
4.Coating:Before the prime coat initial curing,make the well mixed materials be coating on the pending-repair area layer by layer,the coating should be
compacted,the suitable coating thickness is 4-10mm,the most thickness can be 30mm,repair the surface to be smooth after the coating coat in 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.
5.Curing:It can be put into using after curing for 24 hours at the temperature of 25 degree,(If you 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 the iodine tungsten lamp to do irradiation heating with 40cm distance
from the coating.
