power plant pump silicon carbide wearing resistant coatings

power plant desulfurization pump silicon carbide anti wearing abrasion resistant coating
 
Product name
BD7722 power plant desulphurization pump silicon carbide wearing abrasion resistant coatings
 
Product usage
This product is high performance abrasion resistant,corrosion resistant polymeric material which compounded by large crystalline silicon carbide and modified toughened heterocycle resin.It is mainly used for the
repair and pre-protect of the shell, guard plate, impeller and agitator blade of power plant slurry circulating pump, such as desulfurization pump etc.
 
Performance features
1. Hot water resistant,acid resistant,alkali resistant and corrosion resistant
2. With good adhesion,high mechanical strength, no shrinkage after curing.
3. Does not precipitate, does not stratify, does not drip,does not slip,does not loose, construction is convenient.
 
Physical and chemical parameters:

 
Note: the curing conditions of samples (sample blocks) used in all the test data in this note are: 25℃ 24h + 80℃ 4h.
 
How to use:
1. Surface treatment: clear up the pending-repair parts,expose the fresh substrate,do the roughing treatment for the fresh substrate,the treated surface should be a dry, rough, clean surface.
 
2. Using prime coat: The special prime coat (need to be purchased separately, please refer to the instructions for the use of the prime coat) is mixed evenly and coated on the surface of the parts to be repaired in proportion.
The thinner the prime coat is,the better.
 
3. Preparation: accurately weigh out the right amount of A and B components according to the proportion required by product labeling, and stir them thoroughly to mix them evenly.The prepared material should be used up within
the specified operating time (that is, before the material starts to become sticky, and the material after becoming sticky and hard can’t be used again)
 
4. Coating: The suitable coating thickness of this product is 2 to 10mm, and each layer can be coated up to 15mm at most. If the workpiece design requires a thickness of more than 15mm,layered coating should be adopted for construction.
The surface layer should be repaired flat after the repair to the required size (this material can be processed mechanically,and can do rolling and grinding if there is any deviation).The repaired surface has color,degree of finish and other
requirements,can brush coating the appropriate face glue/ topcoat (need to buy) on the wear resistant layer for modification.
 
5. Curing:It can be put into using under the light load after curing 24 hours at room temperature 25℃,when the ambient temperature is too low,heating or prolonging curing time should be used to complete the curing.
 
Special version:
1.The product parameter is obtained for laboratory testing,only for reference,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 25℃,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.
 
 
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.
