Iphepha le-PLA
I-PLA luhlobo lwemilo yomgca we-Aliphatic Polyesters.I-PLA inokusetyenziswa kwiphakheji eqinileyo yeziqhamo, imifuno, amaqanda, ukutya okuphekiweyo kunye nokutya okuqhotsiweyo, ingasetyenziselwa ukupakishwa kwesandwich, ibhiskithi kunye nezinye iipakethi ezinjengeentyatyambo ezintsha.
Ingcaciso yeMveliso
I-Polylactic acid (PLA) inokuchithwa ngokupheleleyo kwi-carbon dioxide kunye namanzi phantsi kweemeko zendalo emva kokulahlwa.Inokumelana kwamanzi okulungileyo, iipropati zomatshini, i-biocompatibility, inokuthi ifakwe kwizinto eziphilayo, kwaye ayinakho ukungcola kokusingqongileyo.Kwangaxeshanye, i-PLA nayo ineempawu ezintle zoomatshini.Inamandla eempembelelo eziphezulu, ukuguquguquka okulungileyo kunye nokuzinza kwe-thermal, iplastiki, ukuqhubekeka, akukho kuguqulwa kwebala, ukunyanzeliswa okulungileyo kwi-oksijini kunye nomphunga wamanzi, kunye nokubonakala kakuhle, i-anti-mildew, i-antibacterial, ubomi benkonzo yi-2 ~ 3 iminyaka.
Eyona nto ibalulekileyo isalathisi sokusebenza kwezinto zokupakisha yi-air permeability, kwaye intsimi yesicelo sale nto ekupakishweni inokumiselwa ngokweendlela ezahlukeneyo zomoya wezinto eziphathekayo.Ezinye izinto zokupakisha zifuna i-oxygen permeability ukubonelela i-oksijini eyaneleyo kwimveliso;ezinye izinto zokupakisha zifuna umqobo kwi-oksijini ngokwezinto eziphathekayo, ezifana nokupakishwa kwesiselo, okudinga izinto ezinokuthintela i-oksijini ukuba ingene kwipakethe ukuze inqanda isikhunta.isiphumo sokukhula.I-PLA inomqobo wegesi, umqobo wamanzi, ukungafihli kunye nokuprintwa kakuhle.
I-PLA inokucaca kakuhle kunye ne-gloss, kwaye ukusebenza kwayo okugqwesileyo kuthelekiswa ne-cellophane kunye ne-PET, engafumanekiyo kwezinye iiplastiki ezinokonakala.Ukungafihli kunye nokucwebezela kwe-PLA ngama-2 ~ 3 amaxesha efilimu ye-PP eqhelekileyo kunye namaxesha angama-10 e-LDPE.Ukucaca kwayo okuphezulu kwenza ukubonakala kokusebenzisa i-PLA njengento yokupakisha intle.Umzekelo, isetyenziselwa ukupakisha iilekese.Okwangoku, iipakethe ezininzi zeelekese kwimarike zisebenzisa iifilimu zokupakisha zePLA.
Ukubonakala kunye nokusebenza kwale filimu yokupakisha kufana neefilimu zendabuko zokupakisha iilekese, kunye nokucaca okuphezulu, ukugcinwa kwekink egqwesileyo, ukuprintwa kunye namandla, kunye neempawu ezibalaseleyo zomqobo, ezinokuthi zigcine ngcono incasa ye-candy.Inkampani yaseJapan isebenzisa i-"racea" brand PLA yeNkampani ye-American Cakir Dow Polymer njengesixhobo sokupakisha seemveliso ezintsha, kwaye ukupakishwa kucace kakhulu ngenkangeleko.I-Toray Industries iphuhlise iifilimu ezisebenzayo ze-PLA kunye nezilayi zisebenzisa ubuchwepheshe bayo be-nano-alloy.Lo mboniso bhanyabhanya unobushushu obufanayo kunye nokuchasana nefuthe njengeefilimu ezisekwe kwipetroleum, kodwa unokwaluka okugqwesileyo kunye nokungafihli.
I-PLA inokwenziwa kwiimveliso zefilimu kunye nokungafihlisi okuphezulu, iipropathi ezilungileyo zesithintelo, ukuqhubekeka okugqwesileyo kunye neempawu zoomatshini, kwaye ingasetyenziselwa ukupakishwa okuguquguqukayo kweziqhamo kunye nemifuno.Inokwenza indawo efanelekileyo yokugcina iziqhamo kunye nemifuno, igcine imisebenzi yobomi yeziqhamo kunye nemifuno, ukulibazisa ukuguga, nokugcina umbala, ivumba, incasa kunye nenkangeleko yeziqhamo nemifuno.Nangona kunjalo, xa isetyenziswa kwizinto zokwenyani zokupakisha, ezinye iinguqulelo ziyafuneka ukuze zilungelelanise neempawu zokutya ngokwazo, ukuze kuphunyezwe isiphumo esingcono sokupakisha.
I-PLA inokwenza indawo ene-acidic ebuthathaka phezu kwemveliso, enesiseko se-antibacterial and antifungal.Ukuba ezinye ii-antibacterial agents zisetyenziselwa ukongeza, izinga lokulwa ne-antibacterial elingaphezulu kwe-90% linokufezekiswa, elingasetyenziselwa ukupakishwa kwe-antibacterial yeemveliso.
Xa kuthelekiswa nefilimu ye-LDPE, ifilimu ye-PLA kunye nefilimu ye-PLA / REO / TiO2, ukunyanzeliswa kwamanzi kwefilimu edibeneyo ye-PLA / REO / Ag iphezulu kakhulu kunezinye iifilimu.Kugqitywe kule nto inokuthintela ngokufanelekileyo ukubunjwa kwamanzi adibeneyo kunye nokufezekisa umphumo wokuvimbela ukukhula kwee-microorganisms;kwangaxeshanye, nayo inefuthe elihle kakhulu le-bacteriostatic.
I-PET / PLA umgca we-extrusion sheet extrusion: i-JWELL iphuhlisa i-parallel twin screw extrusion line ye-PET / PLA ishidi, lo mgca uxhotyiswe nge-degassing system, kwaye akukho mfuneko yokomisa kunye neyunithi ye-crystallizing.Umgca we-extrusion unempahla yokusetyenziswa kwamandla aphantsi, inkqubo yokuvelisa elula kunye nokugcinwa lula.Isakhiwo se-screw esicandiweyo sinokunciphisa ilahleko ye-viscosity ye-PET / PLA resin, i-calender roller ye-symmetrical kunye ne-thin-wall-wall iphakamisa umphumo wokupholisa kunye nokuphucula amandla kunye nomgangatho weshidi.Multi components dosing feeder inokulawula ipesenti yezinto ezinyulu, imathiriyeli yokurisayikilisha kunye nebhetshi enkulu ngokuchanekileyo, iphepha lisetyenziswa ngokubanzi kushishino lokupakisha lwethermoforming.
