Amakuru

Acide Polylactique (PLA) ni polymer ikoreshwa cyane mu nganda nko gupakira, gucapa 3D, hamwe n’imyenda. Nyamara, PLA yunvikana cyane nubushyuhe nubushyuhe, bishobora kugira ingaruka kumikorere no gutunganya neza. Sisitemu ya Crystallizer yumye ifite uruhare runini mugukora ibishoboka byose kugirango PLA igumane ubunyangamugayo nubwiza mugihe cyo gukora. Gusobanukirwa uburyo iyi sisitemu ikora irashobora gufasha abayikora kunonosora uburyo bwabo bwo gutunganya no kunoza imikorere yibicuruzwa.

Sobanukirwa na Crystallisation ya PLA no Kuma
PLA ni polymer amorphous, bivuze ko imiterere ya molekile idafite imiterere isobanutse ya kristalline muburyo bwayo bubi. Crystallisation ni inzira itunganya molekile ya PLA muburyo bwubatswe, byongera ubushyuhe bwayo, imbaraga, nigihe kirekire. Ariko, mugihe cyo korohereza no gukomeza gutunganya, PLA nayo ikuramo ubuhehere buturuka mu kirere, ibyo bikaba bishobora gutuma umuntu yangirika, kugabanuka kwimashini, no gutunganya inenge.
Sisitemu ya Crystallizer yumye yashizweho kugirango ikemure ibyo bibazo icyarimwe korohereza no gukama pellet cyangwa flake ya PLA, ikemeza ko ibereye gusohora, kubumba, cyangwa gucapa 3D.

Ibice by'ingenzi bigize aPLA Crystallizer KumaSisitemu
1. Igice cya Crystallizer
Igice cya kristaliste gifite inshingano zo guhindura amorphous PLA muri kimwe cya kabiri. Iyi nzira ikubiyemo:
• Ubushyuhe bugenzurwa: PLA yashyutswe kurwego runaka rwubushyuhe kugirango itangire korohereza mugihe ikumira.
• Sisitemu yo gukangura: Ibikoresho bikomeza gukangurwa cyangwa gutitira kugirango birinde guhuzagurika no kwemeza kristu imwe.
• Kugenzura Ubushyuhe: Kugena ubushyuhe bwuzuye ni ngombwa kugirango ugere kuri kristu yifuzwa udateze kwangirika kwa PLA.
Sisitemu yo Kuma
PLA imaze gutondekwa, yimuka mugice cyumye, ikuraho ubuhehere burenze kugirango ireme neza. Uburyo bwo kumisha burimo:
• Umwuka wo mu kirere udahumanye: Umugezi wumuyaga ushyushye, ufite ubuhehere buke uzenguruka mu bikoresho, ukurura neza neza.
• Kuma Vacuum cyangwa Desiccant Kuma: Sisitemu zimwe zikoresha kwumisha vacuum cyangwa kumisha desiccant zumye kugirango ugere kurwego rwo hasi cyane.
• Gukomeza Gukurikirana: Sensors ikurikirana urwego rwubushyuhe nubushyuhe kugirango bikame neza.

Uburyo Inzira ikora
Intambwe ya 1: Gupakira ibikoresho bya PLA
Pelletes ntoya, flake, cyangwa granules zashyizwe muri kristu. Ibikoresho mubisanzwe bifite ubushuhe bwinshi, bugomba kugabanuka mbere yo gutunganywa neza.
Intambwe ya 2: Gushyushya no guhagarika umutima
Sisitemu ikoresha ubushyuhe bugenzurwa mugihe gikomeza guhagarika ibikoresho. Ibi byemeza no gutondeka kandi bikarinda gukomera cyangwa guhuzagurika, nikibazo gisanzwe na PLA.
Intambwe ya 3: Inzibacyuho Yicyiciro Cyumye
Nyuma yo kugera kuri kristu yifuzwa, ibikoresho byimukira mucyumba cyumisha, aho umwuka ushyushye, udahumanye ukuraho ubuhehere bukabije. Iyi ntambwe ningirakamaro mu gukumira hydrolytike yangirika, igabanya umutungo wa PLA mugihe cyo gushonga no gushiraho.
Intambwe ya 4: Kugabanya Ubushuhe bwa nyuma
Sisitemu ikomeza gukama kugeza ibirimo amazi bigeze kurwego rwiza rwo gutunganya, mubisanzwe munsi ya 250 ppm (ibice kuri miliyoni). Iyo PLA imaze gukama neza, yiteguye gukoreshwa mugusohora, gushushanya inshinge, thermoforming, cyangwa icapiro rya 3D.

Inyungu zo Gukoresha Sisitemu ya Crystallizer yumye
1. Kunoza ubushyuhe bwo guhangana
Crystallized PLA irashobora kwihanganira ubushyuhe bwo hejuru bwo gutunganya, bigatuma ikenerwa cyane no guterwa inshinge hamwe nubushyuhe bwo hejuru.
2. Kugabanya inenge zo gutunganya
Mugukuraho ubuhehere burenze, sisitemu irinda ibibyimba byinshi, kurwara, no kunanirwa kwa mashini mugihe cyo gukora.
3. Kuzamura ibikoresho bya mashini
Crystallised kandi yumye neza PLA yerekana imbaraga nziza, kuramba, no kurwanya ihinduka.
4. Gukora neza vuba
Hamwe no korohereza icyarimwe no gukama, abayikora barashobora gutunganya PLA neza, kugabanya imyanda yibikoresho nigihe cyo gutaha.

Umwanzuro
Sisitemu ya Crystallizer yumye ni ngombwa mugutezimbere imikorere, igihe kirekire, hamwe nibikorwa bya PLA. Mugucunga neza kristalisiti no kuvanaho ubuhehere, iyi sisitemu itanga ibisubizo byujuje ubuziranenge mubikorwa bitandukanye byo gukora. Gusobanukirwa nuburyo ikora bituma abayikora barushaho gukora neza no guhuza ibicuruzwa, bigatuma PLA ikora biopolymer ihindagurika kandi yizewe kugirango ikoreshwe mu nganda.
