(b) paint process matched therewith corresponding to valve is selected, valve is carried out at integral spray using the paint process matched therewith
Reason；Wherein, every one of painting layer implements lower one of painting layer again after fully drying or solidify.
Further for can not be covered when can coat spraying crack, the position such as corner, avoid after dispatching from the factory, these positions
Occur getting rusty and reduce the phenomenon of its service life, in step (b), before integral spray processing, valve spraying is not easy to cover
The surface of lid is manually precoated using paint process matched therewith.
Further, in step (a1), sharp edge and all coarse cut edges are polished to the circle that radius is at least 2mm
Angle.
Further for preferably carrying out blasting treatment to the surface of valve, in step (a4), in blasting treatment, valve
The temperature of door is at least 5 DEG C, and is more than more than 3 DEG C of air dew point temperature, and relative humidity is less than 85%.
Further, in step (a2), determine that the method surfaces to be coated with the presence or absence of grease pollution is as follows：It is sprayed on and is treated with water
Apply on surface, if forming the globule on surfaces to be coated in 25 seconds, show surfaces to be coated there is grease；Either：With chalk with
By surfaces to be coated, surfaces to be coated there is the light region of chalk trace and have grease stable pressure.
Further for grease is removed well, in step (a2), area is less than 100cm2The removal side of grease zone
Method is：Heavy oil dirt first is removed with perching knife, then wiping contaminated surface with the rag or wire brush for being moistened with solvent again makes grease abundant
Dissolving, is finally wiped dry with clean rag, and wiping will be carried out three or four times, use clean rag every time.
Further for grease is removed well, in step (a2), area is more than 100cm2The removal side of grease zone
Method is：Heavy oil dirt first is removed with perching knife, then sprays water-soluble alkaline emulsifying agent, treats water-soluble alkaline emulsifying agent and grease reaction 5
After minute, with scrub-brush, mop or cleaning pad brushing surface, grease is set fully to dissolve, it is finally light using at least 150 bars of cleaning
Water is clean by surface washing.
Painted well further for that can realize, in step (a3), abrasive material is carried out to valve surface, makes roughness
Between 30~85 μm.
A kind of paint process matched therewith is further provided, described to paint in process matched therewith, painting layer at least has finish paint
And priming paint；The finish paint is acrylic acid top-coat, and the priming paint is quick-drying alcohol acid primer；Either：The finish paint is that polyurethane is mute
Finish coat varnish, the priming paint are quick-drying zinc phosphate primer；Either：The priming paint is the thick slurry priming paint of epoxy；The finish paint is epoxy
Thickness slurry finish paint.
Further provide another paint process matched therewith, it is described paint process matched therewith in, painting layer have finish paint,
Intermediate coat and priming paint；The priming paint is epoxy zinc rich primer, and the intermediate coat is quick setting epoxy cloud iron intermediate coat, and the finish paint is
Fluorine carbon finishing paint；Either：The finish paint, intermediate coat and priming paint are the thick slurry paint of epoxy；Either：The priming paint is inorganic silicic acid
Zinc rich primer, the intermediate coat and the finish paint are organosilicon heat-resistant lacquer.
After employing above-mentioned technical proposal, the present invention has carried out processing early stage to valve, has eliminated valve table before paint
The surface defect in face, the process except grease and removal soluble-salt is carried out to valve surface and valve surface has been ground
Material, reach the roughness of paint requirements, finally to valve surface blasting treatment and Shot Blasting；So paint is compared
It is attached in valve surface well, after valve dispatches from the factory use, improves its service life；In addition, the present invention is in integral spray
Between, artificial precoating is carried out to the place that can not cover of spraying, avoiding these local later stages gets rusty, and is affected by the external environment
Phenomenon.
