Izinto Eziguquliwe Zokubumba Umjovo Ongaboli
Izindlela eziningana zezimboni zithengeka kalula (okungukuthi isisindo samangqamuzana aphezulu) i-PLA.Kusetshenziswa amamonomer amabili amakhulu: i-lactic acid, ne-cyclic di-ester, i-lactide.Umzila ojwayeleke kakhulu oya e-PLA uwukuvula i-lactide nge-polymerization enezinto ezihlukahlukene zensimbi (imvamisa i-tin octoate) ekuxazululeni noma njengokumiswa.Ukusabela okwenziwe nge-metal-catalyzed kuvame ukubangela i-racemization ye-PLA, inciphise ukuqina kwayo uma kuqhathaniswa nokokuqala (imvamisa isitashi sombila).
I-PLA iyancibilika ohlotsheni lwezincibilikisi eziphilayo.I-Ethyl acetate, ngenxa yokufinyeleleka kwayo kalula kanye nengozi ephansi yokusetshenziswa, inentshisekelo enkulu.Intambo yephrinta ye-PLA 3D iyancibilika uma icwiliswe ku-ethyl acetate, iyenze ibe isixazululi esiwusizo sokuhlanza amakhanda e-extruder okuphrinta kwe-3D noma ukukhipha izisekelo ze-PLA.Iphuzu lokubilisa le-ethyl acetate liphansi ngokwanele ukuze liphinde libushelelezi i-PLA ekamelweni lomhwamuko, elifana nokusebenzisa umhwamuko we-acetone ukuze bushelelezi i-ABS.
Ezinye izinyibilikisi eziphephile okufanele zisetshenziswe zihlanganisa i-propylene carbonate, ephephile kune-ethyl acetate kodwa okunzima ukuyithenga ngokuthengisa.I-Pyridine nayo ingasetshenziswa kodwa lokhu akuphephile kangako kune-ethyl acetate ne-propylene carbonate.Iphinde ibe nephunga elibi elihlukile lezinhlanzi.
Izici Zokubumba Umjovo we-SPLA
Izingxenye eziyinhloko zomkhiqizo yi-PLA, i-PBAT kanye ne-inorganic Lolu hlobo lomkhiqizo lunokuncibilika okuhle namandla emishini aphezulu, futhi lufaneleka ngokukhethekile ukubumba umjovo.Ingakhiqiza imikhiqizo enezimbotshana eziningi ngesikhathi esifushane sokupholisa, intengo ephansi, kanye nokuwohloka okusheshayo.Umkhiqizo unokucutshungulwa okuhle kanye nezakhiwo zomzimba, futhi ungasetshenziswa ngokuqondile ekubumbeni umjovo ukwenza imikhiqizo ehlukahlukene ebunjiwe.
Inkambu Yesicelo Sokubumba Umjovo we-SPLA
Ukuqina okuphezulu, amandla aphezulu okuphrinta kwe-3D okuguquliwe,
Izinto eziguquliwe zokuphrinta ze-3D ezingabizi kakhulu, ezinamandla aphezulu
