Iindaba

I-Polylactic Acid (PLA) yipolymer esetyenziswa ngokubanzi kwimizi-mveliso efana nokupakishwa, ushicilelo lwe-3D, kunye namalaphu. Nangona kunjalo, i-PLA inovelwano kakhulu kumswakama kunye nobushushu, obunokuchaphazela iipropathi zayo zomatshini kunye nokusebenza kakuhle. I-PLA Crystallizer Dryer System idlala indima ebalulekileyo ekuqinisekiseni ukuba i-PLA igcina ingqibelelo kunye nomgangatho ngexesha lemveliso. Ukuqonda indlela le nkqubo isebenza ngayo kunokunceda abavelisi baphucule ubuchule babo bokuqhuba nokuphucula ukusebenza kwemveliso.

Ukuqonda i-PLA Crystallization kunye nokomisa
I-PLA yipolymer e-amorphous, oku kuthetha ukuba isakhiwo sayo se-molecular ayinayo ifom ye-crystalline echaziweyo kwimeko yayo ekrwada. I-Crystallization yinkqubo ephinda ihlengahlengise iimolekyuli ze-PLA zibe yifom eyakhiwe ngakumbi, iphucula ukuxhathisa ubushushu, amandla kunye nokuqina. Nangona kunjalo, ngexesha le-crystallization kunye nokuqhubekela phambili, i-PLA iphinda ithathe ukufuma emoyeni, okunokubangela ukuthotywa, ukunciphisa iimpawu zoomatshini, kunye neziphene zokucubungula.
I-PLA Crystallizer Dryer System yenzelwe ukujongana nale mingeni ngokudibanisa kunye nokumisa iipellets ze-PLA okanye ii-flakes ngaxeshanye, ukuqinisekisa ukuba zifanelekile kwi-extrusion, ukubumba, okanye ukushicilelwa kwe-3D.

Amacandelo angundoqo aI-PLA Crystallizer DryerInkqubo
1. Iyunithi yeCrystallizer
Iyunithi ye-crystallizer inoxanduva lokuguqula i-amorphous PLA ibe yi-semi-crystalline state. Le nkqubo ibandakanya:
• Ukushisa okuLawulwayo: I-PLA ifudunyezwa kwiqondo elithile lobushushu ukuze iqalise i-crystallization ngelixa ikhusela ukuthotywa.
• IAgitation System: Isixhobo sishukunyiswa ngokuqhubekayo okanye siyawa ukunqanda ukudityaniswa kunye nokuqinisekisa ukuqaqamba okufanayo.
• Ulawulo lobushushu: Ulawulo oluchanekileyo lobushushu luyimfuneko ukuze kuphunyezwe ubucwebe obufunekayo ngaphandle kokubangela ukuthotywa kwePLA.
2. Inkqubo yokomisa
Nje ukuba i-PLA ikhazimliswe, idlulela kwinqanaba lokumisa, elisusa ukufuma okugqithileyo ukuqinisekisa umgangatho wokuqhuba ongaguqukiyo. Inkqubo yokomisa ibandakanya:
• I-Dehumidified Air Flow: Umjelo womoya oshushu, nobumanzi obuphantsi ujikeleza kwizinto eziphathekayo, ufunxa ukufuma kakuhle.
• I-vacuum okanye i-Desiccant Drying: Ezinye iinkqubo zisebenzisa i-vacuum drying okanye i-desiccant-based drying ukuphumeza amanqanaba aphantsi kakhulu okufuma.
• Ukubeka iliso ngokuqhubekayo: Izinzwa zilandelela amanqanaba okufuma kunye nobushushu ukuze kugcinwe iimeko zokomisa ezona zilungileyo.

Isebenza njani Inkqubo
Inyathelo 1: Ilayisha i-PLA Material
Iipellets ze-PLA ezikrwada, iiflakes, okanye iigranules zilayishwa kwicrystallizer. Isixhobo ngokuqhelekileyo sinomthamo ophezulu wokufuma, ekufuneka uncitshiswe ngaphambi kokuba kuqhutyekwe phambili.
Inyathelo lesi-2: Ukufudumeza kunye nokuphazamiseka
Inkqubo isebenzisa ubushushu obulawulwayo ngelixa iqhubeka iphazamisa izinto. Oku kuqinisekisa i-crystallization kunye nokuthintela ukunamathela okanye ukuxhamla, okuyiyona nto ixhaphakileyo kunye ne-PLA.
Inyathelo lesi-3: Ukutshintshela kwiSigaba Sokomisa
Emva kokufezekisa i-crystallinity efunwayo, izinto eziphathekayo zifudukela kwigumbi lokumisa, apho umoya oshushu, ococekileyo ususa umswakama ogqithiseleyo. Eli nyathelo libalulekile ukuthintela ukuthotywa kwe-hydrolytic, eyenza buthathaka iipropathi ze-PLA ngexesha lokunyibilika kunye nokumila.
Inyathelo lesi-4: UkuNcitshiswa kokuGcina ukufuma
Inkqubo iyaqhubeka nokumisa de isiqulatho sokufuma sifikelele kwinqanaba elifanelekileyo lokusetyenzwa, ngokuqhelekileyo ngaphantsi kwe-250 ppm (iinxalenye ngesigidi). Yakuba yomiswe ngokupheleleyo, iPLA ilungele ukusetyenziswa kwi-extrusion, inaliti yokubumba, i-thermoforming, okanye i-3D yoshicilelo.

IiNzuzo zokuSebenzisa i-PLA Crystallizer Dryer System
1. Ukuphuculwa kokumelana nobushushu
I-Crystallized PLA inokumelana namaqondo obushushu aphezulu, iyenze ilungele ngakumbi ukubumba inaliti kunye nezicelo zobushushu obuphezulu.
2. Iziphene eziNcitshisiweyo zokuSebenza
Ngokususa ukufuma okugqithisileyo, inkqubo ikhusela ukubunjwa kweqamza, i-warping, kunye nokusilela komatshini ngexesha lemveliso.
3. IiPropati zoomatshini eziphuculweyo
ICrystallized kwaye yomiswe ngokufanelekileyo iPLA ibonisa amandla angcono, ukuqina, kunye nokuchasana nokuguqulwa.
