Paub cov PLA khoom siv ntawm 3D luam ntaub ntawv

Muaj ntau cov neeg muas zaub thiab cov phooj ywg nug kuv yog hais tias PLA yog yas? Ntawm no yog ib tug ntxhib tham txog dab tsi yog PLA niaj hnub no.

PLA yog cov lus Askiv tsiaj ntawv ntawm polylactic acid, uas yog sau ntawv raws li: polylacticacid. Polylactic acid (PLA) yog ib tug tshiab biobased thiab biodegradable khoom ua los ntawm cov hmoov txhuv nplej raw cov ntaub ntawv npaj los ntawm txuas ntxiv dua mus tsob nroj kev pab xws li pob kws. Lub hmoov txhuv nplej raw khoom yog tau los ntawm saccharification kom tau qabzib, thiab ces piam thaj thiab ib tug tej yam sab yog fermented rau tsim high-kev coj dawb huv lactic acid, thiab ces ib tug tej yam molecular yuag polylactic acid yog tsim los ntawm tshuaj synthesis. Nws muaj zoo biodegradability. Tom qab siv, nws yuav tau kiag li degraded los ntawm kab mob nyob rau hauv cov xwm nyob rau hauv tej yam tej yam kev mob, thiab thaum kawg ua carbon dioxide thiab dej, uas tsis tsim plua plav paug ib puag ncig. Qhov no yog lig heev rau cov ib puag ncig thiab yog pom zoo raws li ib tug phooj ywg environmentally khoom.

Daim ntawv xaus lus tias cov kev tshwm sim ntawm cov hlau lead, mercury, cadmium, chromium, biphenyl, thiab diphenyl ether twb zoo ib yam nrog rau 11-xyoo EU qhia nyob rau kev siv ntawm kev txwv tshuaj, thiab kev soj ntsuam ntawm cov qauv 001 twb tsis kuaj. ND Tsis dected.

Tag nrho cov saum toj no kev tshawb fawb qhia tau hais tias PLA yog ib tug zoo cov ntaub ntawv uas, tab sis cov zaub mov no xwb ib tug teeb meem ntawm kuj zoo kawg kev txhawj xeeb rau txhua leej txhua tus, los yog yuav tau ceev faj.

Cia kuv tham txog ib co shortcomings thiab kev piam sij ntawm PLA. Ua ntej ntawm tag nrho cov, PLA yog tsis resistant rau siab kub, thiab nws yeej pib deform nyob ib ncig ntawm 60 °. Raws li ib tug khoom noj khoom haus muaj pwm, nws yuav tsum txias kho; PLA ntaub ntawv uas yuav tsum degraded, uas yog ib qho zoo dua thiab ib tug disadvantage. Txawm hais tias nws yog tus phooj ywg environmentally, nws yuav tsum tau 3D printing ntawm cov khoom-qib yam. Check yog ib tug luv luv board; nyob rau hauv lub luam ntawv txheej txheem, vim hais tias nws yog high-kub melting, nws yuav tiv thaiv tus hais, txawm hais tias tus hais lawv tus kheej yog non-toxic, tab sis qhov no yog ib tug me ntsis zoo li PM2.5, ntev-lub sij hawm ua tsis taus pa los yog ib txhia kev puas tsuaj tau rau tib neeg lub ntsws, yog li ntawd, lub 3D printing qhov chaw yog dua ventilated.

Yog li ntawd, PLA yog ib tug phooj ywg environmentally cov khoom uas txhua leej txhua tus yuav siv tau nrog cog qoob loo.
