desulfuration funnel repair wear abrasion resistant coating

BD725 desulfurization gas flue special anti abrasion wear resistant epoxy coating:

Packing specification:
Two component,10Kg/group,packed in a plastic drum

Performance features：
Excellent in wear & corrosion resistance
With very high bonding strength to metal substrates
Convenient for construction,without very high technical requirements for the constructors
It's not precipitated and hierarchical
Suitable for the protecting of high temperature wear,corrosion working condition
Hot water resistant,steam resistant,acid resistant,alkali resistant
Can do blade coating directly for both facade and ceiling,don't drip and slip,without the support

Product usage:
BD725 desulfurization system of wear resistant coating is the high performance high-temperature & wear & corrosion resistant
polymeric ceramic material compounded by high performance wear resistant,corrosion resistant material (like alumina,silicon carbide,carborundum,titanium alloy etc.) and modified toughening heat resistant resin.Widely used in the preparation of wear resistant
coating on the surface of various machine part which has high temperature,wear resistant,corrosion resistant requirements.The highest
temperature resistant can reach to 250℃.

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 4:1,make A and B two component of BD725 desulfurization system of wear resistant coating
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,configuration 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 BD725 desulfurization chimney flue repair wear resistant coating is 2-8mm.Make the mixed-up
material be coating on the pending-repair part layer by layer,the adhesive layer should be compacted,make it infiltrate fully with the substrates.
Repair the surface to be smooth after the coating is coated 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.

4. Curing:Cure for 24 hours at the temperature of 25℃ before using,when the temperature is below 15℃,the adhesive layer can't be fully curing,should heat it up to the temperature of 80℃ and keep this temperature for 2 hours to promote the coating to cure fully after the
coating initial curing(can use iodine tungsten lamp do irradiation heating with 40cm distance from the coating).

Special version:
1.  This parameter is for laboratory conditions,due to the actual working condition is more complex,suggest users do pretest according to actual working condition
2.  When the environment temperature is below 15℃,the curing time will prolong,should take proper heating measure
3. When the environment temperature is more than 25℃ or the mixing quantity is too large,the curing speed will expedite,should properly
shorten the application time of coating after mixing.
4.  Should pay attention to reinforcing ventilation during using.

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