BD7041 slurry pump anti chemical corrosion impact abrasion resistant coating:
Packing specification:
Two component,10Kg/group,packed in a plastic drum,A component: 7.5Kg/drum, B component: 2.5Kg/drum.
performance feature:
large particles ,excellent in wear & corrosion resistance
BD7041 slurry pump abrasion repairing material with metal substrate with high bonding strength
Convenient for construction,without very high technical requirements for constructors
Suitable for the repairing and protecting of various wear,corrosion working condition
product usage:
BD7041 slurry pump wear resistant repair material 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 loading medium
wear-out part and the preparation of wear resistant coatings on the surface of various machine parts which have wear resistant,
corrosion resistant requirements.Such as used in the heavy medium erosive wear repairing and pre-protecting of slurry pump,
swirler/cyclone,classifier,jet flowing machine,grit mouth,slurry blender,conveyer pipeline elbow etc.
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.
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 BD7041 slurry pump wear resistant repair material is 4-8mm,the most thickness can be 30mm,
make the mixed-up material spread 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¡æ before putting into use,(If can heat it up to the 60-80¡æ and keep this temperature for 2 hours,
in this way,can improve 30% comprehensive performance) If the temperature is below 5¡æ,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.
