Yintoni unyango lweCorona Surface?Kutheni iphepha eligqunywe yiPE lifuna unyango lwecorona?

1.Yintoni unyango lweCorona Surface?

Unyango lweCorona yinkqubo yonyango esekwe kakuhle esetyenziswa kakhulu kumashishini ahlukeneyo kwihlabathi liphela.Umgaqo wobu buchwepheshe kukusebenzisa i-high-frequency kunye ne-high-voltage corona discharge kwindawo ephathwayo ukuvelisa iplasma yobushushu obuphantsi, ebangela ukusabela kwe-radical simahla kumphezulu, i-cross-link ye-polymer, irhabaxa umphezulu kwaye inyuse ukumanzi kwayo. kwizinyibilikisi zepolar.

Ezi ion zingena kumphezulu wento eprintiweyo ngomothuko wombane kunye nokungena ukutshabalalisa isakhiwo sayo semolekyuli, i-oxidize kwaye i-polarze iimolekyuli zomphezulu eziphathwayo, kunye nokutshatyalaliswa kombane kwe-ion kutshabalalisa umphezulu, ngaloo ndlela kuphuculwe ukunamathela komphezulu kwi-adhesives, i-inki kunye neengubo.

Unyango lwe-Corona lubonakaliswe njengeyona ndlela isebenzayo nesebenzayo yokwandisa ukumanzisa komphezulu kunye nokuncamathela kwezinto.Ngokuqhelekileyo isetyenziswa kwiindidi zetsimbi, kubandakanywa i-aluminium, igolide, i-titanium, kunye nensimbi engenasici;iiplastiki, ezifana ne-polyethylene kunye ne-polypropylene;iphepha kunye nekhadibhodi, kunye nezinye izinto zokupakisha.

2.Kutheni le nto iphepha lePE eliqatywe nge-PE lifuna unyango lwe-corona?

I-polyethylene ye-Medium / low density (PE) ifakwe kwelinye icala okanye kumacala omabini ephepha elisezantsi elifakwe kwi-coated ngendlela yokugqoka, ebizwa ngokuba yi-single-sided coating kunye necala eliphindwe kabini ngokulandelanayo.

Iphepha elifakwe kwi-PE lisetyenziswe ngokubanzi kwintsimi yokupakisha ukutya (ezifana neekomityi zephepha le-cola, iibhokisi ze-hamburger, njl.) ngenxa yokungena kwamanzi, i-oyile, kunye neempawu ezichasene nobushushu.Nangona kunjalo, kuba iphepha le-PE eligqunywe yi-PE lisisixhobo sokufunxa, kunzima ukuba i-inki ibambelele, ngoko kukho iimfuno ezingqongqo kwinkqubo yonyango lwangaphambili kunye ne-inki yokushicilela.

Emva kokugquma iphepha lesiseko, unyango lwe-corona luyafuneka kwi-coating layer.Kuphela xa umphezulu wengubo emva kokuba unyango lwe-corona ludibane nephepha lesiseko lunokufezekisa umphumo oqinileyo kwaye wenze umkhiqizo ube nomgangatho ongcono.Abathengi amava angcono xa usebenzisa.

Nanning Paperjoy Paperibisebenza ngokukhethekileyo ekuvelisweni kwephepha eligqunywe kwibakala lokutya le-PE iminyaka eli-16.Sinobuchwephesha bemveliso obuphambili kwaye sibonelela ngeenkonzo zokumisa enye ye-PE yokwambathisa, ukuprinta, ukusika ukufa kunye nokunqunyulwa.Iimveliso ikakhulu ziquka i-PE coated paper roll,iphepha indebe esezantsi roll, ifeni yekomityi yephepha, iphepha eligqunywe nge-PE, ibhodi yendlovu egqunywe nge-PE, njl.
