Iphepha le-PLA
I-PLA iwuhlobo lomumo we-Aliphatic Polyesters.I-PLA ingasetshenziswa ephaketheni eliqinile lezithelo, imifino, amaqanda, ukudla okuphekiwe nokudla okugazingiwe, futhi ingasetshenziselwa ukupakisha isangweji, amabhisikidi namanye amaphakheji afana nembali entsha.
Incazelo Yomkhiqizo
I-Polylactic acid (PLA) ingabola ngokuphelele ibe yi-carbon dioxide namanzi ngaphansi kwezimo zemvelo ngemva kokulahlwa.Inokumelana kahle namanzi, izakhiwo zemishini, i-biocompatibility, ingamuncwa izinto eziphilayo, futhi ayinakho ukungcola emvelweni.Ngesikhathi esifanayo, i-PLA nayo inezakhiwo ezinhle zemishini.Inamandla omthelela aphezulu, ukuguquguquka okuhle nokuzinza kokushisa, ipulasitiki, ukucutshungulwa, akukho ukushintsha kombala, ukungena kahle kumoya-mpilo nomhwamuko wamanzi, nokungafihli kahle, i-anti-mildew, i-antibacterial, impilo yesevisi iminyaka engu-2 ~ 3.
Inkomba yokusebenza ebaluleke kakhulu yezinto zokupakisha i-air permeability, futhi inkambu yokusetshenziswa yale nto emaphaketheni inganqunywa ngokuya ngokuhlukahluka komoya kwezinto.Ezinye izinto zokupakisha zidinga ukungena kwe-oxygen ukuze kunikeze umoya-mpilo owanele emkhiqizweni;ezinye izinto zokupakisha zidinga isithiyo ku-oxygen ngokwezinto zokwakha, ezifana nokupakishwa kwesiphuzo, okudinga izinto ezingavimbela i-oksijini ukuthi ingene ephaketheni ukuze ivimbele isikhunta.umphumela wokukhula.I-PLA inomgoqo wegesi, umgoqo wamanzi, obala kanye nokuphrinta okuhle.
I-PLA inokucaca okuhle nokucwebezela, futhi ukusebenza kwayo okuhle kakhulu kuqhathaniswa ne-cellophane ne-PET, engatholakali kwamanye amapulasitiki awonakele.Ukuba sobala nokucwebezela kwe-PLA izikhathi ezingu-2~3 kunefilimu evamile ye-PP futhi izikhathi ezingu-10 kune-LDPE.Ukuba sobala kwayo okuphezulu kwenza ukubukeka kokusebenzisa i-PLA njengento yokupakisha kube kuhle.Isibonelo, isetshenziselwa ukupakisha amaswidi.Njengamanje, amaphakheji amaningi kaswidi emakethe asebenzisa amafilimu okupakisha e-PLA.
Ukubonakala nokusebenza kwale filimu yokupakisha kufana namafilimu endabuko okupakisha amaswidi, anokucaca okuphezulu, ukugcinwa kwe-kink okuhle kakhulu, ukuphrinta namandla, kanye nezakhiwo ezinhle kakhulu zokuvimbela, ezingagcina kangcono ukunambitheka kwe-candy.Inkampani yase-Japan isebenzisa uhlobo lwe-PLA ye-"racea" ye-American Cakir Dow Polymer Company njengomsebenzi wokupakisha wemikhiqizo emisha, futhi ukupakishwa kusobala kakhulu ngokubukeka.I-Toray Industries ithuthukise amafilimu nezingcezu ezisebenzayo ze-PLA isebenzisa ubuchwepheshe bayo bobunikazi be-nano-alloy.Le filimu inokumelana nokushisa nomthelela ofanayo namafilimu asekelwe ku-petroleum, kodwa futhi inokunwebeka okuhle kakhulu nokungafihli lutho.
I-PLA ingenziwa imikhiqizo yefilimu enokucaca okuphezulu, izakhiwo ezinhle zokuvimbela, ukucutshungulwa okuhle kakhulu kanye nezakhiwo zemishini, futhi ingasetshenziselwa ukupakisha okuguquguqukayo kwezithelo nemifino.Ingakha indawo efanelekile yokugcina izithelo nemifino, igcine imisebenzi yokuphila yezithelo nemifino, ibambezele ukuguga, futhi igcine umbala, iphunga, ukunambitheka nokubukeka kwezithelo nemifino.Kodwa-ke, uma kusetshenziswa ezintweni ezipakishwayo zangempela, ezinye izinguquko ziyadingeka ukuze zivumelane nezici zokudla ngokwako, ukuze kuzuzwe umphumela ongcono wokupakisha.
I-PLA ingakha indawo ene-asidi ebuthakathaka ebusweni bomkhiqizo, enesisekelo se-antibacterial kanye ne-antifungal.Uma kusetshenziswa amanye ama-antibacterial agents ngaphezu kwalokho, izinga le-antibacterial elingaphezu kuka-90% lingafinyelelwa, elingasetshenziselwa ukupakishwa kwe-antibacterial yemikhiqizo.
Uma kuqhathaniswa nefilimu ye-LDPE, ifilimu ye-PLA nefilimu ye-PLA/REO/TiO2, ukungena kwamanzi kwefilimu eyinhlanganisela ye-PLA/REO/Ag kuphezulu kakhulu kunamanye amafilimu.Kuphethwa kulokhu ukuthi kungavimbela ngokuphumelelayo ukwakheka kwamanzi ahlanganisiwe futhi kufinyelele umphumela wokuvimbela ukukhula kwama-microorganisms;ngesikhathi esifanayo, futhi inomphumela omuhle kakhulu we-bacteriostatic.
I-PET/PLA yomugqa we-extrusion weshidi lezemvelo: I-JWELL ithuthukisa ulayini we-parallel twin screw extrusion weshidi le-PET/PLA, lo mugqa ufakwe isistimu yokukhipha umoya, futhi asikho isidingo sokumisa nokucwenganisa iyunithi.Ulayini we-extrusion unezici zokusebenzisa amandla aphansi, inqubo yokukhiqiza elula kanye nokugcinwa okulula.Isakhiwo sesikulufu esihlukaniswe izingxenye singanciphisa ukulahleka kwe-viscosity ye-PET/PLA resin, i-symmetrical and thin-wall calender roller iphakamisa umphumela wokupholisa futhi ithuthukise amandla kanye nekhwalithi yeshidi.I-Multi components dosing feeder ingalawula amaphesenti ezinto ezingasetshenziswanga, izinto ezigaywe kabusha kanye neqoqo elikhulu ngokunembile, ishidi lisetshenziswa kabanzi embonini yokupakisha ye-thermoforming.
