I-Biodegradable Injectable Molding Material eGuquliweyo
Iindlela ezininzi zemizi-mveliso zifikelelekayo (oko kukuthi ubunzima obuphezulu bemolekyuli) iPLA. Iimonomers ezimbini eziphambili zisetyenziswa: i-lactic acid, kunye ne-cyclic di-ester, i-lactide. Eyona ndlela ixhaphakileyo eya kwi-PLA kukuvula i-polymerization ye-lactide enezinto ezahlukeneyo zesinyithi (ngokuqhelekileyo i-tin octoate) kwisisombululo okanye njenge-suspension. I-metal-catalyzed reaction idla ngokubangela i-racemization ye-PLA, ukunciphisa i-stereoregularity yayo xa kuthelekiswa nezinto zokuqala (ngokuqhelekileyo i-corn starch).
I-PLA iyanyibilika kuluhlu lwezinyibilikisi eziphilayo. I-Ethyl acetate, ngenxa yokulula kwayo ukufikelela kunye nomngcipheko ophantsi wokusetyenziswa, inomdla kakhulu. I-PLA 3D i-filament yomshicileli iyanyibilika xa ifakwe kwi-ethyl acetate, iyenza i-solvent eluncedo yokucoca i-3D yokushicilela iintloko ze-extruder okanye ukususa izixhaso ze-PLA. Indawo yokubilisa ye-ethyl acetate iphantsi ngokwaneleyo ukuba nayo igudile i-PLA kwigumbi lomphunga, efana nokusebenzisa umphunga we-acetone ukugudisa i-ABS.
Ezinye izinyibilikisi ezikhuselekileyo zokusetyenziswa ziquka ipropylene carbonate, ekhuselekileyo kune-ethyl acetate kodwa kunzima ukuyithenga ngokuthengisa. I-Pyridine nayo ingasetyenziswa kodwa oku akukhuselekanga ngaphantsi kune-ethyl acetate kunye nepropylene carbonate. Kwakhona inevumba elibi lentlanzi elahlukileyo.
Iimpawu zokubumba ze-SPLA zesitofu
Awona macandelo aphambili emveliso arePLA, PBAT kunye ne-inorganic Olu hlobo lwemveliso lunokunyibilika okuhle kunye namandla aphezulu omatshini, kwaye ifaneleke ngakumbi ukubumba inaliti. Inokuvelisa iimveliso ze-multi-cavity kunye nexesha elifutshane lokupholisa, ixabiso eliphantsi, kunye nokuthotywa ngokukhawuleza. Imveliso inomsebenzi olungileyo kunye nezinto ezibonakalayo, kwaye inokusetyenziselwa ngokuthe ngqo ukubumba isitofu ukwenza iimveliso ezibunjiweyo ezahlukeneyo.
Ummandla weSicelo sokuSebenzisa isitofu se-SPLA
Ukuqina okuphezulu, amandla aphezulu e-3D yoshicilelo olulungisiweyo lwezixhobo,
Ixabiso eliphantsi, amandla aphezulu e-3D yokushicilela izinto ezilungisiweyo
