Labarai

PLA (Polylactic Acid) sanannen tushen thermoplastic ne wanda aka sani don haɓakar halittu da dorewa. Koyaya, don cimma ingantacciyar ingancin bugu da kaddarorin injina, filament PLA sau da yawa yana buƙatar takamaiman tsari kafin magani: crystallization. Ana aiwatar da wannan tsari ta amfani da na'urar bushewa ta PLA crystallizer. Bari mu shiga cikin tsarin mataki-by-steki na yin amfani da busar da busar da crystallizer PLA.

Fahimtar Bukatar Crystallization

PLA yana wanzuwa a cikin jihohin amorphous da crystalline. Amorphous PLA ba shi da kwanciyar hankali kuma ya fi dacewa ga warping da canje-canje masu girma yayin bugawa. Crystallization wani tsari ne wanda ke daidaita sarƙoƙin polymer a cikin filament na PLA, yana ba shi ƙarin tsari da kwanciyar hankali. Wannan yana haifar da:

Ingantattun daidaiton ƙira: Crystallized PLA ba shi da yuwuwar yaɗuwa yayin bugawa.

Ingantattun kayan aikin injiniya: Crystallized PLA sau da yawa yana nuna ƙarfi da taurin kai.

Ingantacciyar ingancin bugawa: Crystallized PLA yawanci yana samar da mafi ƙarancin ƙarewa da ƙarancin lahani.

Tsarin Mataki-mataki

Shirye-shiryen Kayayyaki:

Duban Filament: Tabbatar cewa filament ɗin PLA ba shi da kowane gurɓatawa ko lalacewa.

Loading: Load da filament na PLA a cikin na'urar busar da crystallizer bisa ga umarnin masana'anta.

Crystallization:

Dumama: Na'urar bushewa tana dumama filament zuwa takamaiman zazzabi, yawanci tsakanin 150 ° C da 190 ° C. Wannan zafin jiki yana inganta daidaitawar sarƙoƙi na polymer.

Wurin zama: Ana riƙe filament ɗin a wannan zafin jiki na wani takamaiman lokaci don ba da damar yin cikakken crystallization. Lokacin zama na iya bambanta dangane da nau'in filament da matakin da ake so na crystallinity.

Sanyaya: Bayan lokacin zama, filament ɗin yana sanyaya sannu a hankali zuwa zafin jiki. Wannan jinkirin tsarin sanyaya yana taimakawa wajen daidaita tsarin crystalline.

bushewa:

Cire danshi: Da zarar an yi crystallized, filament sau da yawa ana bushewa don cire duk wani danshi mai saura wanda mai yiwuwa ya sha yayin aikin crystallization. Wannan matakin yana da mahimmanci don tabbatar da ingantaccen bugu.

Ana saukewa:

Sanyaya: Bada damar filament ya yi sanyi gaba daya kafin a sauke kaya.

Ajiye: Ajiye filament ɗin da aka yi da crystallized da busasshiyar a cikin akwati da aka rufe don hana shi sake shayar da danshi.

Fa'idodin Amfani da Dryer Crystallizer PLA

Ingantattun ingancin bugawa: Crystallized PLA yana haifar da mafi ƙarfi, mafi ingancin kwafi.

Rage warping: Crystallized PLA ba shi da sauƙi ga warping, musamman don manyan kwafi ko sassa masu haɗaɗɗun geometries.

Ingantattun kayan aikin injiniya: Crystallized PLA sau da yawa yana nuna ƙarfin juriya, juriya mai tasiri, da juriya mai zafi.

Sakamako masu daidaituwa: Ta amfani da na'urar bushewa, za ku iya tabbatar da cewa filament ɗinku na PLA an shirya shi akai-akai don bugawa, yana haifar da ƙarin ingantaccen sakamako.

Zaɓan Na'urar bushewa ta Dama

Lokacin zabar na'urar bushewa ta PLA, la'akari da waɗannan abubuwan:

Ƙarfi: Zaɓi na'urar bushewa wanda zai iya ɗaukar adadin filament da kuke yawan amfani da shi.

Kewayon zafin jiki: Tabbatar da na'urar bushewa na iya isa yanayin zafin ƙirƙira da aka ba da shawarar don takamaiman PLA ɗin ku.

Lokacin zama: Yi la'akari da matakin da ake so na crystallinity kuma zaɓi na'urar bushewa tare da lokacin zama mai dacewa.

Ƙarfin bushewa: Idan ana buƙatar bushewa, tabbatar da bushewa yana da aikin bushewa.

Kammalawa

Yin amfani da na'urar bushewa ta PLA crystallizer mataki ne mai mahimmanci don haɓaka aikin filament na PLA. Ta bin matakan mataki-mataki da aka zayyana a cikin wannan labarin, zaku iya tabbatar da cewa PLA ɗinku an shirya shi da kyau don bugu, yana haifar da ingantaccen sakamako mai inganci.
