Xov xwm

PLA (Polylactic Acid) yog qhov nrov bio-based thermoplastic paub txog nws cov biodegradability thiab sustainability. Txawm li cas los xij, kom ua tiav cov ntawv luam tawm zoo thiab cov khoom siv kho tshuab, PLA filament feem ntau xav tau cov txheej txheem ua ntej kho: crystallization. Cov txheej txheem no feem ntau yog ua los ntawm PLA crystallizer tshuab ziab khaub ncaws. Cia peb delve rau hauv cov txheej txheem ib ntus ntawm kev siv PLA crystallizer tshuab ziab khaub ncaws.

Nkag siab txog Kev Xav Tau Crystallization

PLA muaj nyob rau hauv ob qho tib si amorphous thiab crystalline xeev. Amorphous PLA tsis ruaj khov thiab muaj kev cuam tshuam ntau dua rau kev hloov pauv thiab qhov loj me thaum luam ntawv. Crystallization yog cov txheej txheem uas ua kom cov khoom sib txuas ntawm cov khoom siv polymer hauv PLA filament, muab nws cov qauv ntau dua thiab ruaj khov. Qhov no ua rau:

Txhim kho qhov tseeb qhov tseeb: Crystallized PLA tsis tshua muaj kev sib tw thaum luam ntawv.

Txhim kho cov khoom siv kho tshuab: Crystallized PLA feem ntau pom muaj zog dua thiab tawv.

Cov ntawv luam tawm zoo dua: Crystallized PLA feem ntau ua kom zoo dua qhov ua tiav thiab tsawg dua qhov tsis xws luag.

Cov txheej txheem Step-by-Step

Kev npaj khoom siv:

Filament soj ntsuam: Xyuas kom lub PLA filament tsis muaj cov kab mob los yog puas tsuaj.

Chaw thau khoom: Load PLA filament rau hauv lub tshuab ziab khaub ncaws raws li cov chaw tsim khoom cov lus qhia.

Crystallization:

Cua sov: Lub tshuab ziab khaub ncaws ua kom sov cov filament mus rau qhov kub thiab txias, feem ntau ntawm 150 ° C thiab 190 ° C. Qhov kub no txhawb kev sib dhos ntawm cov saw hlau polymer.

Nyob: Lub filament yog tuav ntawm qhov kub thiab txias rau lub sijhawm tshwj xeeb kom tso cai rau kom tiav crystallization. Lub sijhawm nyob hauv tsev tuaj yeem sib txawv nyob ntawm seb hom filament thiab qib xav tau ntawm crystallinity.

Kev ua kom txias: Tom qab lub sijhawm nyob hauv tsev, cov filament tau txias maj mam mus rau chav sov. Qhov kev ua kom txias qeeb no yuav pab kom ruaj khov rau cov qauv crystalline.

Kev ziab:

Kev tshem tawm noo noo: Thaum crystallized, cov filament feem ntau qhuav kom tshem tawm cov dej seem uas yuav tau nqus thaum lub sij hawm crystallization. Cov kauj ruam no yog qhov tseem ceeb rau kev ua kom pom kev zoo tshaj plaws.

Unloading:

Txias: Cia lub filament kom txias tag ua ntej unloading.

Cia: Khaws cov crystallized thiab qhuav filament nyob rau hauv ib lub thawv kaw kom tiv thaiv nws los ntawm reabsorbing noo noo.

Cov txiaj ntsig ntawm Kev Siv PLA Crystallizer Dryer

Txhim kho kev luam ntawv zoo: Crystallized PLA ua rau cov ntawv luam tawm muaj zog, ntau dua qhov tseeb.

Txo warping: Crystallized PLA tsis tshua muaj kev sib tw, tshwj xeeb tshaj yog rau cov ntawv loj lossis cov khoom nrog cov duab puab.

Txhim kho cov khoom siv kho tshuab: Crystallized PLA feem ntau pom muaj zog tensile ntau dua, cuam tshuam tsis kam, thiab kub tsis kam.

Cov txiaj ntsig zoo ib yam: Los ntawm kev siv lub tshuab ziab khaub ncaws crystallizer, koj tuaj yeem xyuas kom meej tias koj lub PLA filament tau npaj tsis tu ncua rau kev luam ntawv, ua rau cov txiaj ntsig zoo dua.

Xaiv Txoj Cai Crystallizer Dryer

Thaum xaiv PLA crystallizer tshuab ziab khaub ncaws, xav txog cov hauv qab no:

Peev Xwm: Xaiv lub tshuab ziab khaub ncaws uas tuaj yeem ua raws li cov filament koj feem ntau siv.

Qhov kub thiab txias: Xyuas kom lub tshuab ziab khaub ncaws tuaj yeem ncav cuag qhov pom zoo crystallization kub rau koj qhov tshwj xeeb PLA.

Lub sij hawm nyob: Xav txog qhov xav tau ntawm crystallinity thiab xaiv lub tshuab ziab khaub ncaws nrog lub sijhawm nyob hauv tsev.

Kev ziab kom qhuav: Yog xav tau kom qhuav, xyuas kom lub tshuab ziab khaub ncaws kom qhuav.

Xaus

Siv PLA crystallizer tshuab ziab khaub ncaws yog ib kauj ruam tseem ceeb hauv kev ua kom zoo ntawm PLA filament. Los ntawm kev ua raws li cov txheej txheem ib ntus uas tau teev tseg hauv tsab xov xwm no, koj tuaj yeem xyuas kom meej tias koj PLA tau npaj kom zoo rau kev luam ntawv, ua rau muaj txiaj ntsig zoo thiab txhim khu kev qha.
