Amakuru

PLA (Acide Polylactique) ni bio izwi cyane ya bio-thermoplastique izwiho kwangiza ibinyabuzima no kuramba. Ariko, kugirango ugere kubintu byiza byanditse hamwe nubukanishi, filime ya PLA akenshi isaba uburyo bwihariye bwo kubanza kuvura: korohereza. Ubu buryo busanzwe bukorwa hifashishijwe icyuma cyuma cya PLA. Reka ducukumbure intambwe-ku-ntambwe yo gukoresha icyuma cyuma cya PLA.

Gusobanukirwa Gukenera Crystallisation

PLA ibaho muri amorphous na kristaline. Amorphous PLA ntabwo ihagaze neza kandi ikunda guhinduka no guhinduka mugihe cyo gucapa. Crystallisation ni inzira ihuza iminyururu ya polymer muri filament ya PLA, ikayiha imiterere ihamye kandi ihamye. Ibisubizo muri:

Kunonosora ibipimo bifatika: Crystallized PLA ntabwo ishobora guhungabana mugihe cyo gucapa.

Ibikoresho byongerewe imbaraga: Crystallized PLA ikunze kwerekana imbaraga no gukomera.

Ubwiza bwo gucapa neza: Crystallized PLA mubisanzwe itanga ubuso bworoshye burangirana nudusembwa duke.

Intambwe ku yindi

Gutegura ibikoresho:

Igenzura rya filime: Menya neza ko filime ya PLA idafite umwanda cyangwa ibyangiritse.

Gupakira: Shyiramo filime ya PLA mumashanyarazi ya kirisiti ukurikije amabwiriza yabakozwe.

Crystallisation:

Gushyushya: Akuma gashyushya filament ku bushyuhe bwihariye, mubisanzwe hagati ya 150 ° C na 190 ° C. Ubu bushyuhe buteza imbere iminyururu ya polymer.

Gutura: Filime ifatwa kuri ubu bushyuhe mugihe runaka kugirango yemererwe neza. Igihe cyo gutura kirashobora gutandukana bitewe n'ubwoko bwa filament hamwe nurwego rwifuzwa rwa kristu.

Gukonja: Nyuma yigihe cyo gutura, filime ikonjeshwa buhoro buhoro ubushyuhe bwicyumba. Ubu buryo bwo gukonjesha buhoro bifasha guhagarika imiterere ya kristu.

Kuma:

Gukuraho ubuhehere: Iyo bimaze gutondekwa, filament ikama yumye kugirango ikureho ubuhehere busigaye bushobora kuba bwarafashwe mugihe cyo gutegera. Iyi ntambwe ningirakamaro kugirango hamenyekane neza ubuziranenge bwanditse.

Gupakurura:

Gukonjesha: Emerera filament gukonja rwose mbere yo gupakurura.

Ububiko: Bika filime ya kirisiti kandi yumye mu kintu gifunze kugirango wirinde kongera gufata neza.

Inyungu zo Gukoresha PLA Crystallizer Kuma

Kunoza icapiro ryiza: Crystallized PLA ibisubizo mubicapiro bikomeye, murwego rwo hejuru.

Kugabanuka kwintambara: Crystallized PLA ntabwo ikunda kurwana, cyane cyane kubicapo binini cyangwa ibice bifite geometrike igoye.

Ibikoresho byongerewe imbaraga: Crystallized PLA ikunze kwerekana imbaraga zingana, kurwanya ingaruka, no kurwanya ubushyuhe.

Ibisubizo bihoraho: Ukoresheje kristalisiti yumye, urashobora kwemeza ko filime yawe ya PLA ihora yiteguye gucapwa, biganisha kubisubizo byizewe.

Guhitamo Ikariso Yukuri

Mugihe uhitamo icyuma cya kirisiti cya PLA, suzuma ibintu bikurikira:

Ubushobozi: Hitamo akuma gashobora kwakira ingano ya filament usanzwe ukoresha.

Ikirere cy'ubushyuhe: Menya neza ko icyuma gishobora kugera ku bushyuhe bwogusabwa bwa PLA yihariye.

Igihe cyo gutura: Reba urwego rwifuzwa rwa kristu hanyuma uhitemo akuma hamwe nigihe gikwiye cyo gutura.

Ubushobozi bwo kumisha: Niba bikenewe gukama, menya neza ko icyuma gifite umurimo wo kumisha.

Umwanzuro

Gukoresha icyuma cyuma cya PLA ni intambwe yingenzi mugutezimbere imikorere ya filime ya PLA. Ukurikije intambwe ku yindi intambwe ivugwa muri iyi ngingo, urashobora kwemeza ko PLA yawe yiteguye neza gucapwa, bikavamo ibisubizo byiza kandi byizewe.
