I-Biodegradable Injoction yokuhlanganisa okulungisiwe

Imizila eminingana yezimboni ikwazi ukusebenziseka (okungukuthi isisindo esiphakeme se-molecular) Pla. Kusetshenziswa ama-monomers amabili amakhulu: i-lactic acid, kanye ne-cyclic di-ester, i-lactide. Indlela ejwayelekile e-PLA yi-polymerization evulanda yendandatho ye-leactide enama-catalysts ensimbi ahlukahlukene (ngokuvamile uTin Octoate) ngesisombululo noma njengokumiswa. Ukusabela kwensimbi-catalyzed kuvame ukudala ukusebenzelana kwe-pla, kunciphisa i-sterevecularity yayo uma kuqhathaniswa nezinto zokuqala (ngokuvamile isitashi sommbila).

I-PLA iyanyibilika kuhlu lwama-solvents ezi-organic. I-Ethyl Acetate, ngenxa yokutholakala kwayo kalula kanye nengozi ephansi yokusebenzisa, intshisekelo kakhulu. I-Pla 3D Printer Filament iyancibilika lapho ifakwe ku-ethyl acetate, okwenza kube yi-solvent ewusizo yokuhlanza amakhanda e-3D wokuphrinta wokuphrinta noma ukususa ukwesekwa kwe-PLA. Iphoyinti elibilayo le-ethyl acetate liphansi ngokwanele ukuba futhi ibushelelezi ye-PLA egumbini lama-vapor, elifana nokusebenzisa i-acetone vapor ku-abs ebushelelezi.

Amanye ama-solvents aphephile okufanele asetshenziswe kuwo afaka i-propylene Carbonate, ephephe kune-ethyl acetate kodwa kunzima ukuthenga okuthengiswayo. I-pyridine nayo ingasetshenziswa noma kunjalo lokhu kuphephile kancane kune-acetate ye-ethyl kanye ne-propylene Carbonate. Inephunga elibi elibi.
