Izakhiwo zeiifilimu ezininzi ezidityanisiweyozinokwahlulwa zibe ziindidi ezimbini, ezizezi;Okwangoku, iifilimu zokuthintela e-China ziqulunqwe ikakhulu ngamanqwanqwa ama-5, ama-7, ama-8 kunye ne-9.I-symmetrical structural layer yeisithintelo se-multilayer co-extrusioni-diaphragm yenziwe ngeendidi ezintathu zeeleya ezisebenzayo, ezizezi, umaleko wesithintelo, umaleko wokuncamathelisa kunye nomgangatho wenkxaso.
Umaleko wesithintelo: umaleko wesithintelo unemisebenzi yokumelana neoksijini, ukuxhathisa ukufuma kunye nokuthintela ukuvuza kweoyile.Ngolawulo lwezixhobo zomqobo kunye nobukhulu, ukusebenza komqobo wezinto zefilimu kunokulungiswa ukuze kuhlangatyezwane neemfuno zokupakisha ezahlukeneyo (izinto zokuthintela ezisetyenziswa ngokuqhelekileyo kwimarike ziquka i-PA, i-EVOH, i-PVDC, njl.
Uluhlu oluxhasayo: ngokuqhelekileyo, izinto ze-symmetrical structural zinamaleko amabini axhasayo.Uluhlu lwangaphakathi lusetyenziselwa ukutywinwa kobushushu, obuyi-heat-sealing layer, ngelixa umgca wangaphandle usetyenziswa ngokuthe ngqo njengoluhlu lwangaphandle okanye umgca wokushicilela wefilimu yokupakisha.Uluhlu lwenkxaso luya kuba namandla afanelekileyo omatshini, ukusebenza kokutywinwa kobushushu, ukumelana nomphunga wamanzi, ukungafihli kunye nokuprintwa.Izinto eziqhelekileyo zolu maleko yi-LDPE okanye i-LDPE/LLDPE yomxube wezinto.
I-Bonding layer: indima ye-bonding layer kukudibanisa i-barrier layer kunye ne-support layer ukuze kuqinisekiswe amandla okuxobula phakathi kweengqimba.Ukukhethwa kwezixhobo zokudibanisa kunye nobukhulu ngokuqhelekileyo kuxhomekeke kwizinto zokuncedisa umaleko kunye nomgangatho wokuthintela kunye namandla afunekayo okudibanisa ukumisela izinto zokunamathela ezisetyenziselwa umgca wokudibanisa.
Ngexesha elifanayo, ubukhulu boluhlu ngalunye bunokulungelelaniswa ngenkqubo ye-extrusion.Ngokuhlengahlengisa ubukhulu boluhlu lwesithintelo kunye nomlinganiselo wezinto eziluhlaza, ifilimu eneempawu zomqobo ezahlukeneyo inokuveliswa ngokuguquguqukayo.Izixhobo zokutywinwa kobushushu zingatshintshwa kwaye zilungelelaniswe ukuhlangabezana neemfuno zokupakisha ezahlukeneyo.I-multilayer kunye ne-multi-functional co-extrusion composite yikhokelo ephambili yokuphuhliswa kwezinto zefilimu zokupakisha kwixesha elizayo.
Ukuze kwandiswe ubomi beshelufu yokutya kwangoku kunye nokupakishwa kweziyobisi, izinto ezininzi zokupakisha zisebenzisa iifilimu ezihlanganisiweyo ezininzi ezidibeneyo.Kwisicelo, ibonisa ngokupheleleyo iimpawu ezigqwesileyo zokuqinisekiswa komgangatho, ukugcinwa okubandayo, ukukhuselwa kwencasa, ixesha elide leshelufu, ukuchasana kwe-asidi kunye ne-alkali, ukunyanzeliswa komswakama kunye nokubanda, ukumelana nokushisa, ukushisa okuphantsi kunye nokumelana nokugcinwa okubandayo, kunye namandla aphezulu kakhulu.
