BD709 pipeline elbow impact wear abrasion resistant protective epoxy ceramic coatings

Product usage of our BD709 channel bend abrasion impact resistant epoxy compound coating:
BD709 pipeline elbow impact resistant wear resistant coating is the high performance wear & impact resistant polymerization
material compounded by high performance wear resistant aggregate(silicon carbide,alumina,carborundum etc.) and special high
polymer material.It can be blade coating,with good water resistance and high bonding strength,excellent in wear & impact
resistance.Used in the wear repairing of equipment overflowing parts and the preparation of impact & wear resistant coatings on
the whole equipment overflowing parts,exclusively used in the surface wear repairing of magnetic separator roller or the
preparation of wear & impact resistant coatings on the roller surface directly,exclusively used in repairing chute,centrifuge
and ball mill end cover.

Performance feature:
1.Two component,black daub shape,can cure at room temperature,heat for curing can get better comprehensive properties.
2.Excellent in wear & corrosion & impact resistance,the wear resistance is 5 times more than PU rubber,20 to 30 times more
than common mixing rubber,the impact resistance is 10 to 15 times more than imported wear resistant protective agent.
3.Can single use,with the better bonding strength to metal substrate through using it together with primer.
4.Can do blade coating,easily forming,construction is convenient,can achieve seamless coverage of equipment overflowing parts.
5.Suitable for the partial repairing and whole protecting of the equipment under the working condition of higher wear & impact
resistant requirements.

How to use:
1.Surface treatment: Do coarsening treatment on the pending-repair part,(sand blasting treatment will get the best effect,if it doesn't have sand blasting condition,can do grinding treatment
with angle grinder),
the surface after coarsening treatment should be cleaned by cleaning agent(can use acetone,ethyl acetate etc.),
then dry it by airing,the surface after this treatment should be the coarsening,clean and fresh metal substrates.

(Make the special undercoat of BD709 impact & wear resistant coating mix uniformly according to specified percentage,
and brush coating on the substrate surface,then wait for the undercoat curing)

2.Preparation: After undercoat fully curing,according to the specified ratio,make A and B component of BD709
channel bend impact & wear resistant coating 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 5Kg,
every time configure too much adhesives,the curing speed is fast,hasn't been used up until the adhesive has already partial
cured and can't be used.

3.Coating: The suitable coating thickness of BD709 is 3~10mm,make the mixed-up material be coating on the undercoat surface,the adhesive layer should be compacted.Repair the surface to be smooth
after the coating is coated on the required size.

4.Curing condition:It(the equipment) can be put into using after curing for 24 hours at room temperature of 25 degree,it(the equipment) can
also be put into using after this operation of initial curing for 2 hours at room temperature of 25 degree,then heat it up to the temperature of
100 degree and keep this temperature for 2-3 hours,after that cooling it down to room temperature 25 degree,in this way,it can improve 30% comprehensive performance.If the temperature is below 10 degree,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.

Range of application:Used in the partial repairing and whole protecting under the working condition of the equipment which has
higher wear & impact resistant requirements.Such as:power plant coal transportation system transflux part,
all coal washery transflux part,mining transport,separation system etc.Especially suitable for moist or underwater environment,
avoid using in high temperature transportation system.Such as:slurry agitation tank,agitator blade,magnetic separator roller,
belt conveyor roller,centrifuge,vibrating screen girder propping,ball mill end cover,chute,pipeline,elbow etc.

Packing specification:
Packed in a plastic drum, 20Kg/drum, two component, A component: 16Kg/drum, B component: 4Kg/drum.

Transportation storage:
1.Sealed storage in the cool and dry place.The warranty period is 12 months.
2.Avoid placing it upside down,knocking against and transporting it as a non-dangerous product during transportation.

Special version:
1.This parameter is for laboratory conditions,due to the actual working condition is more complex,suggest the users to do
the pretest according to actual working condition

2.When the environment temperature is below 15 degree,the curing time will prolong,should take proper heating measure

3.When the environment temperature is more than 25 degree or the mixing quantity is too large,the curing speed will expedite,should properly shorten the application time of coating
after mixing.

Construction protective measures:
1.Wear the protective masks,wear the protective glasses and rubber gloves
2.Need washing hands with soap before eating,drinking or smoking.
3.The health hazard after touching: a few people will have skin allergy phenomenon,see a doctor in time and avoid touching with
this product again.should wipe it with ethyl acetate when the sizing material paste on the skin by careless,
then wash it with clear water.Should wash it with clear water immediately and see a doctor when splashing into
the eyes by careless.

Warm Prompt:
Residual adhesive solution cured products are non-toxic harmless organic solid,but maybe it will produce poisonous gas
when burning,non-professional personnel can not do combustion disposal,should be sent to garbage power plant or
garbage burning place treatment.

Fire prevention measures:
Should choose dry powder to extinguish fire,can cover and flap it with dry powder,grit(the construction using abrasive)
or the non chemical fiber fabric when the sizing material catching fire.
