Nkhani

PLA (Polylactic Acid) ndi mankhwala otchuka a bio-based thermoplastic omwe amadziwika chifukwa cha biodegradability komanso kukhazikika kwake. Komabe, kukwaniritsa mulingo woyenera kusindikiza khalidwe ndi katundu makina, PLA filament zambiri amafuna yeniyeni chisanadze mankhwala ndondomeko: crystallization. Izi zimachitika pogwiritsa ntchito chowumitsira chowumitsa cha PLA. Tiyeni tifufuze ndondomeko ya pang'onopang'ono yogwiritsira ntchito PLA crystallizer dryer.

Kumvetsetsa Kufunika kwa Crystallization

PLA ilipo m'maiko onse amorphous ndi crystalline. Amorphous PLA sikhazikika komanso sachedwa kusinthasintha komanso kusintha kwa mawonekedwe panthawi yosindikiza. Crystallization ndi njira yomwe imagwirizanitsa maunyolo a polima mkati mwa PLA filament, ndikuwapatsa dongosolo lokhazikika komanso lokhazikika. Izi zimabweretsa:

Kuwongolera kowoneka bwino: Crystallized PLA ndiyocheperako kupindika panthawi yosindikiza.

Makina okhathamiritsa: Crystallized PLA nthawi zambiri imawonetsa mphamvu komanso kuuma kwakukulu.

Kusindikiza kwabwinoko: Crystallized PLA nthawi zambiri imatulutsa zomaliza zosalala komanso zolakwika zochepa.

Ndondomeko ya Pang'onopang'ono

Kukonzekera Kwazinthu:

Kuyang'ana kwa Filament: Onetsetsani kuti PLA filament ilibe zoipitsa zilizonse kapena kuwonongeka.

Kutsegula: Kwezani ulusi wa PLA mu chowumitsira kristalo molingana ndi malangizo a wopanga.

Crystallization:

Kutentha: Chowumitsira chimatenthetsa ulusi kuti ukhale wotentha kwambiri, nthawi zambiri pakati pa 150°C ndi 190°C. Kutentha uku kumalimbikitsa kuyanjanitsa kwa maunyolo a polima.

Pokhala: Filament imasungidwa kutentha uku kwa nthawi yeniyeni kuti ilole kusungunuka kwathunthu. Nthawi yokhalamo imatha kusiyanasiyana kutengera mtundu wa filament komanso mulingo wofunikira wa crystallinity.

Kuziziritsa: Pambuyo pa nthawi yokhalamo, ulusi umakhazikika pang'onopang'ono mpaka kutentha. Kuzizira pang'onopang'ono kumeneku kumathandiza kukhazikika kwa kristalo.

Kuyanika:

Kuchotsa chinyontho: Mukawunikiridwa, filament nthawi zambiri imawuma kuti ichotse chinyezi chilichonse chomwe chingakhale chotengedwa panthawi ya crystallization. Gawoli ndilofunika kwambiri kuti mutsimikizire kuti zosindikiza zili bwino.

Kutsitsa:

Kuziziritsa: Lolani kuti ulusiwo uziziziretu musanatulutse.

Kusungirako: Sungani ulusi wonyezimira ndi wouma mu chidebe chotsekedwa kuti zisatengerenso chinyezi.

Ubwino Wogwiritsa Ntchito PLA Crystallizer Dryer

Kusindikiza kwapamwamba: Crystallized PLA imapangitsa kuti zikhale zolimba, zolondola kwambiri.

Kuchepetsa kumenyera nkhondo: Crystallized PLA simakonda kugwa, makamaka pamadindo akulu kapena magawo okhala ndi ma geometries ovuta.

Katundu wamakina okhathamiritsa: Crystallized PLA nthawi zambiri imawonetsa kulimba kwamphamvu, kukana mphamvu, komanso kukana kutentha.

Zotsatira zogwirizana: Pogwiritsa ntchito chowumitsira kristalo, mukhoza kuonetsetsa kuti PLA filament yanu imakonzedwa nthawi zonse kuti isindikizidwe, zomwe zimapangitsa kuti mukhale ndi zotsatira zodalirika.

Kusankha Chowumitsira Crystal Choyenera

Posankha chowumitsira kristalo cha PLA, ganizirani izi:

Kuthekera: Sankhani chowumitsira chomwe chingagwirizane ndi kuchuluka kwa ulusi womwe mumagwiritsa ntchito.

Kutentha kosiyanasiyana: Onetsetsani kuti chowumitsira chikhoza kufika kutentha kwa crystallization komwe kukulimbikitsidwa kwa PLA yanu yeniyeni.

Nthawi Yokhala: Ganizirani za mulingo womwe ukufunidwa wa crystallinity ndikusankha chowumitsira chokhala ndi nthawi yoyenera yokhala.

Kuyanika mphamvu: Ngati kuyanika ndikofunikira, onetsetsani kuti chowumitsira chili ndi ntchito yowumitsa.

Mapeto

Kugwiritsa ntchito chowumitsira makristali cha PLA ndi gawo lofunikira pakuwongolera magwiridwe antchito a PLA filament. Potsatira ndondomeko yomwe yafotokozedwa m'nkhaniyi, mukhoza kuonetsetsa kuti PLA yanu yakonzedwa bwino kuti isindikizidwe, zomwe zimapangitsa kuti mukhale ndi zotsatira zapamwamba komanso zodalirika.
