Iindaba

I-PLA (i-Polylactic Acid) yinto eyaziwayo ye-bio-based thermoplastic eyaziwa ngokuba yi-biodegradability kunye nokuzinza. Nangona kunjalo, ukufezekisa umgangatho ophakamileyo wokushicilela kunye neempawu zomatshini, i-PLA filament isoloko ifuna inkqubo ethile yonyango lwangaphambili: i-crystallization. Le nkqubo idla ngokuqhutywa kusetyenziswa isomisi sekristali se-PLA. Makhe sihlolisise inkqubo yenyathelo nenyathelo lokusebenzisa isomisi sekristali sePLA.

Ukuqonda imfuneko yeCrystallization

I-PLA ikhona kuzo zombini i-amorphous kunye ne-crystalline states. I-Amorphous PLA ayizinzanga kwaye ithandeka ngakumbi kwi-warping kunye notshintsho lwe-dimensional ngexesha loshicilelo. I-Crystallization yinkqubo elungelelanisa i-polymer chain ngaphakathi kwe-PLA filament, inika isakhiwo esicwangcisiweyo kunye nesizinzileyo. Oku kubangela ukuba:

Ukuchaneka komgangatho ophuculweyo: ICrystallized PLA ayinakwenzeka ukuba ijike ngexesha loshicilelo.

Iipropathi zoomatshini eziphuculweyo: ICrystallized PLA ihlala ibonisa amandla aphezulu kunye nokuqina.

Umgangatho ongcono wokuprinta: ICrystallized PLA ihlala ivelisa umphezulu ogudileyo ogqityiweyo kunye neziphene ezimbalwa.

Inkqubo yeNyathelo ngeNyathelo

Ukulungiswa kwezinto:

Ukuhlolwa kweFilament: Qinisekisa ukuba i-PLA filament ayinayo nayiphi na into engcolileyo okanye umonakalo.

Ukulayisha: Layisha i-PLA filament kwi-crystallizer dryer ngokwemiyalelo yomenzi.

Crystallization:

Ukufudumeza: Isomisi sifudumeza umcu kwiqondo lobushushu elithile, eliphakathi kwe-150°C kunye ne-190°C. Eli qondo lobushushu likhuthaza ukulungelelaniswa kwamatyathanga epolymer.

Indawo yokuhlala: I-filament ibanjwe kule qondo lokushisa ixesha elithile ukuze ivumele i-crystallization epheleleyo. Ixesha lokuhlala lingahluka ngokuxhomekeke kuhlobo lwe-filament kunye nenqanaba elifunwayo le-crystallinity.

Ukupholisa: Emva kwexesha lokuhlala, i-filament ipholiswa ngokukhawuleza kwiqondo lokushisa. Le nkqubo yokupholisa kancinane inceda ukuzinzisa ubume bekristale.

Ukomisa:

Ukususwa kobumanzi: Emva kokuba i-crystallized, i-filament isoloko yomiswa ukuze isuse nayiphi na intsalela yomswakama enokuthi ifakwe ngexesha lenkqubo ye-crystallization. Eli nyathelo libalulekile ekuqinisekiseni umgangatho ongowona woshicilelo.

Iyakhupha:

Ukupholisa: Vumela i-filament iphole ngokupheleleyo ngaphambi kokuba ukhulule.

Ugcino: Gcina imicu ekhazimlisiweyo kunye neyomisiweyo kwisikhongozelo esitywiniweyo ukukuthintela ukufunxa kwakhona ukufuma.

IiNzuzo zokuSebenzisa i-PLA Crystallizer Dryer

Ukuphuculwa komgangatho woshicilelo: I-Crystallized PLA iphumela kukomelele, kushicilelo oluchanekileyo.

Ukunciphisa i-warping: ICrystallized PLA ayithandeki kangako ekujikeni, ngakumbi kushicilelo olukhulu okanye iinxalenye ezinejiyometri entsonkothileyo.

Iipropathi zoomatshini ezomeleziweyo: ICrystallized PLA ihlala ibonisa amandla aphezulu, ukumelana nefuthe, kunye nokuxhathisa ubushushu.

Iziphumo ezihambelanayo: Ngokusebenzisa i-crystallizer dryer, unokuqinisekisa ukuba i-PLA filament yakho ilungiselelwe ngokuqhubekayo ukushicilelwa, okukhokelela kwiziphumo ezithembekileyo.

Ukukhetha i-Crystallizer Dryer eLungileyo

Xa ukhetha i-PLA crystallizer dryer, qwalasela ezi zinto zilandelayo:

Umthamo: Khetha isomisi esinokwamkela isixa sefilament oqhele ukusisebenzisa.

Uluhlu lobushushu: Qinisekisa ukuba isomisi sinokufikelela kubushushu obucetyiswayo becrystallization kwiPLA yakho ethile.

Ixesha lokuhlala: Qwalasela inqanaba elifunekayo lekristale kwaye ukhethe isomisi esinexesha elifanelekileyo lokuhlala.

Ukomisa amandla: Ukuba ukomisa kuyafuneka, qinisekisa ukuba isomisi sinomsebenzi wokomisa.

Ukuqukumbela

Ukusebenzisa i-PLA crystallizer dryer linyathelo elibalulekileyo ekuphuculeni ukusebenza kwe-PLA filament. Ngokulandela inkqubo yenyathelo ngenyathelo echazwe kweli nqaku, unokuqinisekisa ukuba i-PLA yakho ilungiselelwe ngokufanelekileyo ukuprintwa, okukhokelela kwiziphumo ezikumgangatho ophezulu kunye nezithembekileyo.
