Yintoni unyango lweCorona Surface? Kutheni iphepha eligqunywe nge-PE lifuna unyango lwecorona?

1. Yintoni unyango lweCorona Surface?

Unyango lweCorona yinkqubo yokunyanga umphezulu esele imiselwe kakuhle esetyenziswa kakhulu kumashishini ahlukeneyo kwihlabathi liphela. Umgaqo wale teknoloji kukusebenzisa ukukhutshwa kwecorona okuphindaphindekayo kunye nombane ophezulu kumphezulu ocociweyo ukuvelisa iplasma yobushushu obuphantsi, ebangela iimpendulo ze-free radical kumphezulu, idibanise i-polymer, irhawuze umphezulu kwaye yonyuse ukufuma kwawo kwi-polar solvents.

Ezi ion zingena kumphezulu wento eprintiweyo ngokutshoka ngombane kunye nokungena ukuze zitshabalalise isakhiwo sayo seemolekyuli, zidibanise kwaye zidibanise iimolekyuli zomphezulu ezicociweyo, kwaye ukutshoka ngombane kweeion kuyawutshabalalisa umphezulu, ngaloo ndlela kuphucula ukunamathela komphezulu kwiiglu, ii-inki kunye neengubo.

Unyango lweCorona luye lwabonakaliswa njengeyona ndlela isebenzayo nesebenzayo yokuphucula ukufuma komphezulu kunye nokunamathela kwezinto. Isetyenziswa rhoqo kwiintlobo ngeentlobo zesinyithi, kubandakanya i-aluminium, igolide, i-titanium, kunye nentsimbi engatyiwayo; iiplastiki, ezifana ne-polyethylene kunye ne-polypropylene; iphepha kunye nekhadibhodi, kunye nezinye izinto zokupakisha.

2. Kutheni iphepha eligqunywe nge-PE lifuna unyango lwe-corona?

I-polyethylene ephakathi/ephantsi enoxinano (PE) igqunywe kwicala elinye okanye kumacala omabini ephepha elisisiseko eligqunywe ngohlobo logqunywe, olubizwa ngokuba lugqunywe macala omabini kunye nogqunywe macala amabini ngokwahlukeneyo.

Iphepha eligqunywe nge-PE lisetyenziswa kakhulu kwicandelo lokupakisha ukutya (njengeekomityi zephepha le-cola, iibhokisi ze-hamburger, njl.njl.) ngenxa yeempawu zalo ezilungileyo zokungangeni manzi, ukumelana neoyile, kunye nokumelana nobushushu. Nangona kunjalo, ekubeni iphepha eligqunywe nge-PE liyinto engafunxiyo, kunzima ukuba i-inki inamathele, ngoko ke kukho iimfuno ezingqongqo kwinkqubo yalo yonyango lwangaphambi komphezulu kunye ne-inki yokuprinta.

Emva kokugquma iphepha elisezantsi, unyango lwe-corona luyafuneka kumaleko wokugquma. Kuphela xa umphezulu wokugquma emva kokugquma udibene nephepha elisezantsi apho inokuthi ifumane isiphumo esiqinileyo kwaye yenze imveliso ibe nomgangatho ongcono. Amava abathengi angcono xa beyisebenzisa.

Iphepha leNanning Paperjoy Ibe yingcali ekuveliseni iphepha eligqunywe nge-PE elikumgangatho wokutya kangangeminyaka eli-16. Sineteknoloji yemveliso ephucukileyo kwaye sinikezela ngeenkonzo zokugqunywa nge-PE, ukuprinta, ukusika nge-die kunye nokusika. Iimveliso ziquka ikakhulu i-PE coated paper roll, indebe yephepha esezantsi, ifeni yekomityi yephepha, iphepha eligqunywe nge-PE, ibhodi ye-ivory egqunywe nge-PE, njl.njl., zithengiswa kakuhle kumazwe nakwimimandla engaphezu kwe-100 kwihlabathi liphela.
