Uma ufuna ukugcina umkhiqizo wakho uphephile futhi uvikelekile ukuze udayiswe, kungenzeka ukuthi usuyibonile kakade ukuthi ifilimu yokuncipha ingakusiza wenze lokho.Kunezinhlobo eziningi zefilimu eshwabene emakethe namuhla ngakho-ke kubalulekile ukuthola uhlobo olulungile.Hhayi kuphela ukuthi ukukhetha uhlobo olulungile lwefilimu eshwabana kuzosiza ekuvikeleni umkhiqizo wakho eshalofini, kodwa futhi kuzothuthukisa ulwazi lokuthenga kumakhasimende akho noma abathengi.
Ezinhlotsheni eziningi zefilimu eshwabene, izinhlobo ezintathu eziyinhloko zefilimu emakethe ozofuna ukuzibuyekeza yi-PVC, i-Polyolefin, ne-Polyethylene.Lawa mafilimu ashwabene ngalinye linezimfanelo ezidlulela kwezinye izinhlelo zokusebenza, kodwa izici ezithile zalawa mafilimu zingawenza afanelekele ukusetshenziswa kwakho okuthile.
Nawa amandla kanye nobuthakathaka bohlobo ngalunye lwefilimu eshwabene ukukusiza ukuthi ukhethe ukuthi iyiphi engase ilungele uhlelo lwakho lokusebenza.
● I-PVC (eyaziwa nangokuthi i-Polyvinyl Chloride)
Amandla
Le filimu incane, iyathandeka, futhi ilula, ngokuvamile iyathengeka kakhulu kunamafilimu amaningi ashwabanayo.Ishwabana ibheke ohlangothini olulodwa kuphela futhi imelana kakhulu nokuklebhuka noma ukubhoboza.I-PVC inesethulo esicacile, esicwebezelayo, esiyenza ibukeke ngobuhle.
Ubuthakathaka
I-PVC iyathambisa futhi imibimbi uma izinga lokushisa likhuphuka kakhulu, futhi iba lukhuni futhi ibe brittle uma iphola.Ngenxa yokuthi ifilimu ine-chloride kuyo, i-FDA igunyaze kuphela ifilimu ye-PVC ukuthi isetshenziswe nemikhiqizo engenakudliwa.Lokhu kuphinda kubangele ukuthi ikhiphe intuthu enobuthi ngesikhathi sokushisisa nokuvala, okwenza kudingeke ukuthi isetshenziswe ezindaweni ezinomoya omuhle kakhulu.Ngakho-ke le filimu inezindinganiso eziqinile zokulahla.I-PVC ngokuvamile ayifaneleki ukuhlanganisa imikhiqizo eminingi.
● I-Polyolefin
Amandla
Lolu hlobo lwefilimu i-shrink lugunyazwe i-FDA ukuthintana nokudla njengoba ingenayo i-chloride kuyo, futhi ikhiqiza iphunga elincane kakhulu ngesikhathi sokushisisa nokuvala.Ifaneleka kangcono kumaphakheji anomumo ongajwayelekile njengoba incipha ngokugcwele.Ifilimu inendawo enhle, ecwebezelayo futhi icace ngendlela emangalisayo.Ngokungafani ne-PVC, ingamelana nobubanzi obubanzi kakhulu bokuguquguquka kwezinga lokushisa lapho igcinwa, ilondoloza i-inventory.Uma udinga ukuhlanganisa izinto eziningi, i-polyolefin iyisinqumo esihle.Ngokungafani ne-PE, ayikwazi ukugoqa amaphakethe amaningi wezinto ezinzima.I-Cross-linked polyolefin iyatholakala futhi ekhulisa amandla ayo ngaphandle kokudela ukucaca.I-Polyolefin iphinde igaywe kabusha ngo-100%, iyenze ibe ukukhetha "okuluhlaza".
Ubuthakathaka
I-Polyolefin ibiza kakhulu kunefilimu ye-PVC, futhi ingase idinge ukubhobozwa kwezinye izinhlelo zokusebenza ukugwema amaphakethe omoya noma izindawo ezinamabhampa.
● I-polyethylene
Olunye ulwazi olwengeziwe: Ifilimu ye-polyethylene ingasetshenziselwa ukuncipha kwefilimu noma ifilimu elula, kuye ngokuthi ifomu.Uzodinga ukwazi ukuthi iyiphi ifomu oyidingayo ngomkhiqizo wakho.
Abakhiqizi benza i-polyethylene lapho bengeza i-ethylene ku-polyolefin phakathi nenqubo ye-polymerization.Kunezinhlobo ezintathu ezahlukene ze-Polyethylene: i-LDPE noma i-Low-density Polyethylene, i-LLDPE noma i-Linear Low-density Polyethylene, ne-HDPE noma i-polyethylene e-High-density.Ngayinye inezinhlelo ezihlukahlukene zokusebenza, kodwa ngokuvamile, ifomu le-LDPE lisetshenziselwa ukugoqa amafilimu.
Amandla
Kuyazuzisa ukugoqa amaphakethe amaningi wezinto ezinzima-isibonelo, inani elikhulu leziphuzo noma amabhodlela amanzi.Ihlala isikhathi eside futhi iyakwazi ukwelula ngaphezu kwamanye amafilimu.Njenge-polyolefin, i-polyethylene igunyazwe yi-FDA ukuthintana nokudla.Nakuba amafilimu e-PVC nawe-polyolefin elinganiselwe ngogqinsi, ngokuvamile afika ku-0.03mm kuphela, i-polyethylene ingenziwa isikali ifike ku-0.8mm, iyenze ibe ilungele ukusonga izimoto ezifana nezikebhe ukuze zigcinwe.Isebenzisa isukela kwinqwaba noma ekudleni okuqandisiwe kuya ezikhwameni zikadoti kanye ne-palletizing njengokugoqa.
Ubuthakathaka
I-polyethylene inezinga lokushwabana elicishe libe ngu-20% -80% futhi ayicace njengamanye amafilimu.I-polyethylene iyashwabana ngenkathi ipholisa ngemva kokuba isishisisiwe, okwenza kudingeke ukuba kube nesikhala esengeziwe sokupholisa ekupheleni komhubhe wakho wokushwabana.
