Akụkọ

PLA (Polylactic Acid) bụ thermoplastic na-ewu ewu nke dabere na biodegradability na nkwado ya. Otú ọ dị, iji nweta ezigbo ebipụta àgwà na n'ibu Njirimara, PLA filament na-achọkarị a kpọmkwem tupu ọgwụgwọ usoro: crystallization. A na-eme usoro a site na iji igwe ihicha kristal PLA. Ka anyị banye n'ime usoro nzọụkwụ site n'iji igwe nkụ nke PLA crystallizer.

Ịghọta mkpa maka crystallization

PLA dị na steeti amorphous na kristal. Amorphous PLA anaghị akwụsi ike yana ọ na-adịkarị mfe ịgbagha na mgbanwe akụkụ n'oge mbipụta. Crystallization bụ usoro na-ejikọta ụdọ polymer n'ime filament PLA, na-enye ya usoro iwu na nke kwụsiri ike. Nke a na-ebute:

Nhazi akụkụ emelitere: Crystallized PLA adịchaghị agbawa n'oge mbipụta.

Ngwongwo igwe emelitere: Crystallized PLA na-egosipụtakarị ike na isi ike.

Àgwà mbipụta ka mma: Crystallized PLA na-arụpụtakarị ihe dị nro n'elu ala yana ntụpọ ole na ole.

Usoro nzọụkwụ-site-nzọụkwụ

Nkwadebe ihe:

Nleba ihe eji eme ihe: Gbaa mbọ hụ na filament PLA enweghị mmerụ ma ọ bụ mmebi ọ bụla.

Ibunye: Bunye filament PLA n'ime igwe nkụ kristal dịka ntuziaka onye nrụpụta siri dị.

Crystallization:

Ịkpọ oku: Dryer na-ekpo ọkụ filament n'otu okpomọkụ, na-adịkarị n'etiti 150 ° C na 190 ° C. Ọnọdụ okpomọkụ a na-akwalite nhazi nke ụdọ polymer.

Ebe obibi: A na-ejide filament na okpomọkụ a maka oge a kapịrị ọnụ iji mee ka kristal zuru ezu. Oge obibi nwere ike ịdịgasị iche dabere na ụdị filament na ọkwa kristal chọrọ.

Ntụ oyi: Mgbe oge obibi ahụ gasịrị, a na-ajụkwa filament ahụ nwayọọ nwayọọ ruo n'ime ụlọ. Usoro a dị nwayọọ nwayọọ na-enyere aka mee ka nhazi nke crystalline kwụsie ike.

Mwepụ mmiri mmiri: Ozugbo kristal kpụrụ ya, a na-akpọkarị filament ahụ iji wepụ mmiri ọ bụla fọdụrụnụ nke nwere ike itinye n'ime ya n'oge usoro kristal. Nzọụkwụ a dị oké mkpa iji hụ na ọ dị mma ebipụta.

Na-ebutu:

Ntụ oyi: Kwe ka filament ahụ jụọ kpamkpam tupu ebutu ya.

Nchekwa: Chekwaa filament kristal na akpọnwụwo n'ime akpa ejiri mechie ka ọ ghara ịmịghachi mmiri mmiri.

Uru nke Iji PLA Crystallizer Dryer

Ọdịmma ebipụta emelitere: Crystallized PLA na-ebute mbipụta siri ike karịa, nke ziri ezi karịa.

Mbelata warping: Crystallized PLA adịchaghị mfe ịlụ ọgụ, ọkachasị maka mbipụta buru ibu ma ọ bụ akụkụ nwere geometries siri ike.

Ihe eji arụ ọrụ emelitere: Crystallized PLA na-egosipụtakarị ike tensile dị elu, nguzogide mmetụta, yana nguzogide okpomọkụ.

Nsonaazụ na-agbanwe agbanwe: Site n'iji igwe nkụ kristal, ị nwere ike hụ na a na-akwado PLA filament gị mgbe niile maka mbipụta, na-eduga na nsonaazụ ndị a pụrụ ịdabere na ya.

Ịhọrọ kristal Dryer nke ziri ezi

Mgbe ị na-ahọrọ igwe nkụ nke kristal PLA, tụlee ihe ndị a:

Ike: Họrọ igwe nkụ nke nwere ike ịnabata ọnụ ọgụgụ filament ị na-ejikarị.

Oke okpomoku: Gbaa mbọ hụ na igwe nkụ nwere ike iru okpomọkụ kristal akwadoro maka PLA gị.

Oge obibi: Tụlee ọkwa kristal achọrọ wee họrọ igwe nkụ nke nwere oge obibi kwesịrị ekwesị.

Ike ihicha: Ọ bụrụ na achọrọ ihicha, hụ na igwe nkụ nwere ọrụ ihicha.
