Chii chinonzi Corona Surface Treatment?Nei PE yakavharwa bepa ichida kurapwa kwekorona?

1. Chii chinonzi Corona Surface Treatment?

Kurapa kweCorona inzira yakanyatsogadziriswa pamusoro pekurapa iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana pasirese.Nheyo yeiyi tekinoroji ndeyekushandisa yakakwira-frequency uye yakakwira-voltage corona discharge panzvimbo yakarapwa kugadzira yakaderera-tembiricha plasma, iyo inokonzeresa mahara radical reaction pamusoro, kuyambuka-inobatanidza iyo polymer, kushatisa pamusoro uye kuwedzera kunyorova kwayo. kune polar solvents.

Ioni idzi dzinopinda pamusoro pechinhu chakadhindwa nemagetsi kuvhunduka uye kupinda kuti iparadze chimiro chayo chemolecular, oxidize uye polarize mamorekuru epamusoro akabatwa, uye ion electric shock inobvisa pamusoro, nekudaro ichivandudza kunamatira kwepamusoro kune zvinonamira, ingi uye machira.

Kurapa kweCorona kwakaratidza kuti ndiyo inonyanya kushanda uye inoshanda nzira yekukwidziridza kunyorova kwepamusoro uye kunamatira kwezvinhu.Inowanzoshandiswa pamhando dzakasiyana-siyana dzesimbi, kusanganisira aluminium, goridhe, titanium, uye simbi isina tsvina;mapurasitiki, akadai se polyethylene uye polypropylene;bepa uye kadhibhodhi, uye zvimwe zvinhu zvekurongedza.

2.Sei PE yakavharwa bepa ichida kurapwa kwecorona?

Medium/low density polyethylene (PE) yakavharwa kune rimwe divi kana mativi ese maviri egasi rakavharwa bepa nenzira yekupfekedza, iyo inonzi yakashongedzwa nedivi rimwe uye mativi maviri-aviri zvakateerana.

Pepa rakaputirwa PE rakashandiswa zvakanyanya mumunda wekurongedza chikafu (senge makola mapepa emakapu, mabhokisi ehamburger, nezvimwewo) nekuda kweiyo yakanaka isina mvura, mafuta-uchapupu, uye inodzivirira kupisa.Zvisinei, sezvo PE yakavharwa bepa iri chinhu chisingatore, zvakaoma kuti ingi ibatike, saka pane zvakaomesesa zvinodikanwa pane yayo yepamusoro pretreatment process uye kudhinda inki.

Mushure mekuputira bepa rekutanga, kurapwa kwe corona kunodiwa kune iyo yekuputira layer.Chete kana iyo yekumusoro yejasi mushure mekurapwa kwecorona yasangana nebepa repasi inogona kuwana yakasimba mhedzisiro uye kuita kuti chigadzirwa ive nani.Vatengi chiitiko chiri nani kana uchiishandisa.

Nanning Paperjoy Pepayanga iri nyanzvi mukugadzira chikafu-giredhi PE yakavharwa bepa kwemakore gumi nematanhatu.Isu tine tekinoroji yekugadzira yepamberi uye inopa imwe-kumira masevhisi ePE coating, kudhinda, kufa-kucheka uye kutsemura.Zvigadzirwa zvinonyanya zvinosanganisira PE yakavharwa bepa roll,bepa mukombe pasi mupumburu, feni yemukombe wepepa, PE yakavharwa bepa pepa, PE yakavharwa nenyanga dzenzou, nezvimwewo, inotengesa zvakanaka munyika dzinopfuura zana nematunhu pasirese.
