Itekhnoloji yePhepha eliLaminated lePaperjoy Deciphers Core: Unyango lweCorona luyiphucula njani i-PE Coating Adhesion?
Kwimveliso ye iphepha elifakwe ilamineti ekupakisheni ukutya, Ukunamathela kwe-PE coating kumisela ngokuthe ngqo ukuqina kunye nokhuseleko lwemveliso, kwaye luphawu oluphambili lokulinganisa Iphepha Elilaminethiweyo umgangatho.I-PaperjoyIPhepha (iNanning Paperjoy Paper Co., Ltd.) kudala libandakanyeka kwinkonzo yorhwebo lwangaphandle lokupakisha ukutya okufakwe iphepha elilaminethiweyo. Namhlanje, lichaza iteknoloji ephambili yangaphambi kokulaminethwa – unyango lwe-corona, lityhila indlela eliyiphucula ngayo ngokuzinzileyo ukunamathela kwe-PE coating kwaye liphepha iziphene zemveliso.
Unyango lweCorona luyindlela ephambili yokulungiselela unyango iphepha elinamekiweyoimveliso, enomgaqo ocacileyo: Umbane ohamba rhoqo kunye nombane ophezulu (i-voltage 5000-15000V/㎡) usetyenziswa phakathi kwe-electrode yokukhupha kunye ne-roller yonyango lwe-corona ezinikeleyo (eyenziwe ngerabha ye-silicone okanye i-ceramic, enokumelana nobushushu obuphezulu, ukumelana ne-ozone kunye nokufakelwa okunamandla). Xa i-voltage idlula kwi-ionization resistance ye-1-2mm air gap, umoya uyafakwa kwi-ionization ukuze kuveliswe inani elikhulu le-ozone. I-Ozone i-oxidize iimolekyuli zomphezulu weplastiki ukuze zenze iikhompawundi ze-carbonyl kunye neeperoxides. Kwangaxeshanye, i-plasma ichaphazela umphezulu wefilimu, iphula imixokelelwane ye-polymer kwaye ibangele iimpendulo ze-oxidative cross-linking – ekugqibeleni iphucula kakhulu uxinzelelo lomphezulu wefilimu kwaye iphucula ngokusisiseko ukunamathela kweenkqubo ezilandelayo zokuprinta, ukunamathela kunye ne-lamination.
Iqela leengcali likaPaperjoy lithi ukusetyenziswa konyango lwe-corona kufuna ukuqonda iingongoma ezimbini eziphambili:
①Umbane ozinzileyo kunye namandla: Umbane kufuneka uhlale ugcinwe ngaphezulu kwe-6KV kwaye amandla angabi ngaphantsi kwe-6KW. Ingakumbi kwinkqubo yokukhupha i-extrusion lamination, izinto ezisisiseko kufuneka ziphathwe nge-corona yomphezulu ophakathi. Umbane ongonelanga okanye unyango olunganelanga luya kukhokelela ngokuthe ngqo ekungoneleni koxinzelelo lomphezulu wezinto ezisisiseko, nto leyo ebangela iziphene ezifana nokuqhekeka kwe-PE coating kunye ne-delamination.
②Isiphumo sokucoca umphezulu: Unyango lweCorona lunokususa ngaxeshanye ioyile, umswakama kunye nokungcola kumphezulu wefilimu, lususe imiqobo kwiinkqubo zokuncamathela ezilandelayo, luphucule ukunamathela kwe-inki yokuprinta kwaye lunciphise izinga leziphene kwiimveliso ezigqityiweyo.
Ngokusekelwe kuphando olunzulu malunga nobuchwepheshe bephepha eliyi-laminated core, i-Paperjoy yenze inkqubo yokulungelelanisa iiparameter zonyango lwe-corona evuthiweyo kunye nemigangatho yokusebenza esebenzayo. Ingabonelela ngenkxaso yobugcisa eyenzelwe wena kumashishini okupakisha ukutya kwihlabathi liphela ngokwezixhobo ezahlukeneyo zesiseko, izixhobo ze-PE kunye neemfuno zemveliso, kubandakanya ukwenziwa ngcono kweeparameter zonyango lwe-corona, iingcebiso zokulungelelanisa izixhobo zesiseko kunye nezicwangciso zokuphucula umgangatho wenkqubo ye-laminated, ukusombulula ngokuchanekileyo iingongoma zentlungu zemveliso yabathengi.
