Yav li cas uas cuam tshuam rau qhov hnyav ntawm lactic acid PLA cov nta?

Nyob rau hauv lub ntiaj teb ntawm cov khoom uas tsim los ntawm lactic acid PLA — xws li glas, pab, thiab tshwj xeeb yog tshuab—nws zoo ib txwm paub tias yav li cas yuav ua rau cov khoom no zoo lossis phem. Qhov hnyav ntawm cov khoom no cuam tshuam los ntawm ob peb yam uas koj yeej xav tias nws muaj zog heev tab sis tuaj yeem sau rau hauv lwm hom kev lwm yam.

Kawm cov nqis ntawm polymer blend ratios thiab cov khoom ntxhiab.

Thaum peb tham txog kev ua cov khoom ntawm lactic acid PLA, peb nquag muab nws nrog lwm cov ntaub ntawv kom nws muaj zog los yog ua kom nws muaj cov yam ntxwv tshwj xeeb. Cov no yog hu ua additives. Qhov ntawd ua rau peb tswj hwm qhov muaj zog lossis hloov pauv li cas cov khoom kawg yuav yog los ntawm kev sib txawv ntawm cov lactic acid PLA peb sib xyaw nrog cov tshuaj ntxiv, uas yog hu ua polymer blend ratios. Qee cov tshuaj ntxiv tuaj yeem ua rau lactic acid PLA lo ua ke zoo dua, thiab qee qhov tuaj yeem ua rau nws tsis tawg yooj yim. Txoj kev sib xyaw ua ke thiab cov khoom siv ntxiv yog sib piv rau kev sib xyaw cov ntawv qhia zoo rau cov khoom lag luam uas tsis muaj zog thiab kav ntev.

Kev nyob ntawm teeb li, zog, thiab kev sov kho taws rau PLA.

Yuav ua li cas peb cua sov thiab txias lactic acid PLA kuj cuam tshuam tus nqi ntawm lub zog nws muaj. Thaum peb sov nws, nws tau mos thiab peb tuaj yeem tsim nws raws li peb xav tau. Tab sis yog hais tias peb txias nws sai heev, nws yuav tsis muaj sij hawm los teem tag nrho thiab solidify, thiab yuav tsis muaj zog thiab nkig. Los ntawm kev tswj qhov kub, siab, thiab txias / tus nqi zog thaum lub sijhawm tsim khoom, peb tuaj yeem xyuas kom meej tias peb cov txheej txheem lactic acid PLA ua rau muaj zog thiab muaj zog lactic acid PLA cov khoom los tiv thaiv txhua yam ntawm pob thiab ntog.

Kev hiaj hloov ntawm ob npaug thiab kev sib sau los ntawm kev zoo ntawm cov neeg ua haujlwm.

Lactic acid PLA muaj cov ntaub ntawv nrov uas ua los ntawm cov molecular chains uas tau khoom sib txuas rau hauv qee qhov kev. Koj lub kaum thiab lub distribution ntawm cov chains no, lossis cov branches, hauv cov khoom lag luam tuaj yeem cuam tshuam ntau rau hauv nws cov mechanical properties. Ib qho ntev dua thiab lwm tus kheej tsawg branch feem ntau muaj qhov zoo li cas, qhov chaw ntsos dav heev thiab cov chain ntau dua tuaj yeem ua rau cov khoom lag luam flexibile dua. Thaum peb paub tias cov factors no cuam tshuam li cas rau hauv cov mechanical properties ntawm lactic acid PLA, peb tuaj yeem kho qhov kev tsim khoom kom cov khoom lag luam muaj qhov zoo li peb xav.

Kev cuam tshuam ntawm kev hla, UV exposure, thiab teeb ntawm qhov PLA degradation.

cov ntaub ntawv lactic acid PLA yog qhov tseem ceeb tab sis lawv kuj yuav raug phom sij thaum lawv pom qhov chaw nyob hauv qee qhov kev nyob uas feem ntau ua rau lawv hlo li ntawm thaum lawv tsim los ntawm thaum lawv siv. Cov kev nyob zoo li qhov so, UV los ntawm dej tshuaj, thiab qhov txiab npaum heev tuaj yeem ua rau cov ntaub ntawv phom sij thiab ntxuav, ua rau nws yooj yim rau teeb lossis puab. Txhawm rau kho qhov no, cov neeg loj ua tham kom sau lactic acid PLA cov ntaub ntawv hauv qhov chaw ntog thiab khov tawg ntawm dej. Los ntawm kev coj tus ntau yam no zoo, lawv tuaj yeem tso cai rau zoo thiab ua haujlwm rau ob peb xyoo.

lub cheebtsam thiab cov pobke xws li kev them ntsig siab ntawm cov ntaub ntawv

Yog kom paub tseeb tias peb cov lactic acid PLA cov khoom lag luam ua raws li qauv siab tshaj plaws, peb yuav tsum sim thiab tsim kho rau hauv qauv thaj. Peb tuaj yeem sim cov khoom no nyob rau hauv ob peb hom sim, xws li sim txoj hlis, sim pob, thiab sim kev puas ntsoog, kom paub tias lawv ua haujlwm li cas nyob rau hauv cov kev siv sib txawv thiab cov ntsiab cai uas yooj yim pom los ntawm kev phom sij huv. Yog tswj hwm rau qauv thiab lwm yam uas muaj saib xyuas, peb tuaj yeem tswj kom lactic acid PLA peb tsim yog ib chov hlau zoo, ua tau ntev, thiab zoo siab.

Thaum ntev mus, kev huv ncig ntawm cov lactic acid PLA yam ntxwv yog nyob ntawm ob peb qhov chaw sib txawv, thiab yog li ntawd nws yog qhov yooj yim kom pom thiab kho cov no. thaum peb hla tias cov khoom siv polymer, cov ntxhua, kev tsav tsis ua haujlwm, cov molecular structure, qhov chaw uas siv thiab cov lus qhia rau kev sim, peb tuaj yeem tsim cov khoom uas tsis tsuas yog zoo ib thiab nyiam xeeb tab sis kuj muaj cov cai zoo hauv qhov chaw uas siv. Sunfeng puas xav kom ua cov lactic acid PLA zoo dua thiab paub tias cov neeg siv khoom xav tau thiab kho qhov kev ua lag luam.
