Description
Technical field
The present invention relates to a kind of methods of hydrophobic antifouling wearproof nano paint and the antifouling wearproof nano paint of coated with hydrophobic.
Background technology
Demister blocks one of the problem of fouling is common in wet desulfuration tower, and demister is caused to block the main shadow of fouling
It rings because being known as demister surface nature, flushing and smoke property etc..In flue gas after wet desulphurization containing a large amount of acid mists, particle with
And a small amount of heavy metal particle, if cannot effectively remove, it will cause a series of influence to equipment and ambient enviroment.In order to keep away
Exempt to block scale formation appearance, mist separator of desulfurization is installed in wet desulfuration tower.The operation principle of demister is to utilize flue gas
Inertial impaction trapping drop, collected by the Gravitative Loads of drop and be recycled in slurries.The primary demister of board-like demister
Blade pitgh is wide, can clean up and down, and final stage demister is since blade pitgh is narrow, and usually exit is not provided with nozzle punching
It washes, therefore fouling and blocking probability are more serious than primary demister.The microcosmic transformation of board-like demister causes the drop of trapping
By quick drainage, improved board-like demister is more than the slurries that traditional board-like demister is collected within the unit interval, because
This proposes the improved thinking of coating to board-like demister, and the influence of fouling is reduced using coating.It is applied in demister blade surface
Upper super-hydrophobic antifouling resistance to acid attack nano coating is extended with the efficiency for reducing the adherency of impurity, increasing resistance to corrosion, improving cleaning
The service life and cleaning cycle of blade.The antiscale that North China Electric Power University wool grass proposes demister plate face overlay film or coating after imperial or royal seal is thought
Road；Feng Wanchun etc. is proposed is sustained surfactant in the external coating last layer of demister and drop contact, prevents fouling from showing
The appearance of elephant；Yang Qinglong etc. has invented a kind of novel self-cleaning demister blade, and surface is additionally provided with non-sticking lining, and non-sticking lining is complete
The surface of all standing ontology, and the thickness of non-sticking lining is not less than 0.1mm；Pungent news of Wuhan Engineering Univ etc. has been invented a kind of from clear
The surface treatment method of clean antiblocking demister blade, including：1) superchlorinated polyvinyl chloride resin layer is obtained in demister blade surface；2)
UV photocureable coating is coated in superchlorinated polyvinyl chloride resin layer surface, then sprays super hydrophobic coating.These methods are to demister blade
Surface carries out the phenomenon that processing can fundamentally avoid demister blade fouling from blocking, and reduces scale removal cost.Although whole remove
Fog effect improves, but for the no big improvement of trapping of micron order droplet, and wear resistance is to be improved, because
Fouling and clogging are may result in once wearing for coating surface, thus develops a kind of hydrophobic antifouling wearability of micro/nano-scale
Nano coating becomes the emphasis of the area research.

Enter the water of the parts by weight of 0.8 parts by weight -1.2 and the acetic acid of the parts by weight of 1.7 parts by weight -2.2, carry out generation organic hybrid Ludox
Hydrolysis to get organic hybrid Ludox；
By the modified manometer silicon dioxide of the parts by weight of 7.8 parts by weight -8.2 and by the organic miscellaneous of the parts by weight of 6.5 parts by weight -7.2
SiClx colloidal sol mixes, and obtains hydrophobic antifouling wearproof nano paint；
The reaction time of the generation modified manometer silicon dioxide hydrolysis is 5-12 hours, generates organic hybrid Ludox
Hydrolysis reaction time be 5-12 hours.
4. the method for the antifouling wearproof nano paint of coated with hydrophobic, it is characterised in that include the following steps：
A, the surface of the component to needing the antifouling wearproof nano paint of coated with hydrophobic starts the cleaning processing；
B, component is put into claims 1 or 2 or 3 obtained hydrophobic antifouling wearproof nano paints and impregnated 10 minutes -20 minutes
After be slowly withdrawn, then stand component, make the coating nature levelling of parts surface；
C, the component after the levelling of surface is toasted 30 minutes -60 minutes under the conditions of 50 DEG C -70 DEG C；
D, by component, rear baking carries out heat cure in 30-60 minutes at 110 DEG C-120 DEG C, you can.
