Nzira yekugadzirisa sei uye kushandisa pfuti yekupfapfaidza?

1.Tenzi kupfapfaidza pressure.Kuti usarudze kupfapfaidza kwakaringana, zvinhu zvakawanda zvinofanirwa kutariswa, serudzi rwekupfeka, rudzi rwekutetepa, viscosity mushure mekunyungudika, etc. Panguva yekupfapfaidza, iyo yemvura inogadzirwa ichave atomized zvakanyanya sezvinobvira, uye evaporation. yezvinonyungudutsa zviri mumudziyo wemvura zvichava zvishoma sezvinobvira.Kazhinji, kudzora kumanikidza ndeye 0.35-0.5 MPa kana jekiseni rekuyedza rinoitwa.Kuti uwane mhedzisiro inodiwa, zvinodikanwa kukudziridza tsika yakanaka yekunyatsotevedzera zvigadziro zvekuvaka zvinopihwa nemugadziri wechigadzirwa chependi.
2.Master chimiro chemhute.Zvakakosha kuyera mhute pabepa rekuvhara usati wapfapfaidza, inova kuyerwa kwakadzama kwechinhambwe chepfuti yekupfapfaidza uye mhepo.Munguva yekuyedzwa, kana chanza chavhurika, chinhambwe chiri pakati pemuromo nemadziro chinenge chakafara cheruoko rumwe.Dhonza chinosimudzira kuzasi uye chisunungure pakarepo.Pendi yakapfapfaidzwa ichasiya mucherechedzo wakanaka pairi.
3.Master kukurumidza kufamba kwepfuti yespray.Iyo yekumhanyisa inofamba yepfuti yekupfapfaidza inoenderana nekuoma kwekumhanya kwejasi, ambient tembiricha uye coating viscosity.Kazhinji, kumhanya kwekufamba kunenge 0.3m/s.Kana kukurumidza kufamba kwakakurumidza, firimu repende richava rakaoma uye risina kusimba, uye nzvimbo yekuenzanisa yefirimu yepende haina kunaka.Kufamba zvishoma nezvishoma kuchaita kuti firimu repende rive gobvu uye rive mhango.Kumhanya kwemaitiro ese kunofanirwa kuenderana.
4.Master nzira yekupfapfaidza uye nzira.Kupfapfaidza nzira dzinosanganisira vertical overlapping method, horizontal overlapping method uye vertical and horizontal alternating spraying method.Nzira yekupfapfaidza inofanira kubva kumusoro kusvika pasi, kubva kuruboshwe kuenda kurudyi, kubva kumusoro kusvika pasi, uye kubva mukati kuenda kunze.Fambisa pfuti yekupfapfaidza zvakatsiga maererano nerwendo rwakarongwa, sunungura chibatiso paunosvika kumagumo erwendo rwenzira imwe chete, uye wodzvanya chibatiso kuti utange kupfapfaidza mutsara wepakutanga uchidzokera kumashure.
