PLA Film yog dab tsi?

PLA yog cov yas opaque haum rau ua cov khoom siv kho mob nrog rau cov ntawv siv prototyping. PLA yog cov yas muaj zog tab sis nkig uas tsis tuaj yeem siv rau hauv cov ntawv thov uas muaj kev poob siab. Cov lactic acid tsev blocks ntawm PLA tuaj yeem tsim los ntawm cov hmoov txhuv nplej siab, xws li pob kws, nyob rau hauv kev tswj xyuas. Nws siv zog tsawg dua los tsim PLA dua li cov roj av-raws li cov thermoplastics, ua rau nws tus phooj ywg zoo. PLA feem ntau suav hais tias yog biodegradable. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias PLA tsis degrade ib puag ncig hauv ib puag ncig thiab yuav tsum tau muab tso rau hauv cov txheej txheem tshwj xeeb xws li qhov kub ntawm tsawg kawg 60 degree, thiab av noo ntawm 90% uas yuav tsum tau khaws cia nyob rau lub sijhawm ntawm 60 mus rau 90 noj. PLA decomposes rau hauv carbon dioxide, lactic acid, thiab dej.

Polylactic acid (PLA) yog bioplastic ua los ntawm kev rov ua dua monomers muaj cov tshuaj formula C3H4O2. Chemically, PLA yog tsim los ntawm lactic acid molecules. Cov lactic acid yog fermented los ntawm cov nroj tsuag teeb meem nyob rau hauv precisely tswj tej yam kev mob. Lub lactic dimer yog tsim los ntawm dehydrating lactic acid thiab ces thermally degrading lactic acid oligomers. Cov lactide yog polymerized siv lub nplhaib-qhib polymerization nyob rau hauv lub xub ntiag ntawm ib tug catalyst.

Leej twg tsim PLA?

Nyob rau hauv lub xyoo pua 20th thaum ntxov, quantum physics tau hloov chemistry los ntawm kev piav qhia, piv txwv li, yuav ua li cas covalent bonds tsim polymers. Lub tuam txhab lag luam loj DuPont tau txiav txim siab tias nws yuav tsum tau txais kev nqis tes ua vim tias cov kev tshawb pom no tau ua rau muaj kev cuam tshuam zoo kawg nkaus ntawm chemistry.

Ib tug ntawm cov kws tshawb fawb DuPont tau nrhiav nyob rau hauv 1927 yog cov organic chemist Wallace Carothers. Nws lub chaw tshawb fawb tau tsim cov polymers uas DuPont yuav mus ua lag luam li Nylon thiab Neoprene. Carothers kuj tsim PLA tab sis tau ntau xyoo tom qab DuPont cov txheej txheem tsim khoom kim heev rau cov lag luam uas tsis yog kev lag luam tshuaj.

Flash rau pem hauv ntej mus rau xyoo 1990 thaum tus kws tshuaj zoo tshaj plaws hu ua Patrick Gruber txiav txim siab tias nws yuav pab xaus lub ntiaj teb kev cia siab rau roj av. Ib lub lis piam, Gruber thiab nws tus poj niam chemist Sally tau ua tiav thawj pawg ntawm pob kws-raws li PLA ntawm lawv lub qhov cub.

Dab tsi yog cov teeb meem nrog PLA yas?

Txhawm rau pov tseg PLA cov yas kom zoo, koj yuav tsum xa lawv mus rau qhov chaw lag luam. Cov chaw no siv cov kev tswj hwm ib puag ncig kom nrawm nrawm. Txawm li cas los xij, cov txheej txheem tseem tuaj yeem siv sijhawm txog 90 hnub.

Txhawm rau tsim PLA, koj xav tau cov pob kws loj heev. Raws li kev tsim PLA txuas ntxiv thiab kev thov nce ntxiv, nws tuaj yeem cuam tshuam tus nqi ntawm pob kws rau kev lag luam thoob ntiaj teb. Ntau tus kws tshuaj ntsuam xyuas zaub mov tau sib cav tias cov peev txheej ntuj tsim tau zoo dua siv hauv kev tsim khoom noj, tsis yog cov khoom ntim khoom. Nrog 795 lab tus tib neeg hauv ntiaj teb tsis muaj zaub mov txaus los ua lub neej noj qab haus huv, puas tsis qhia txog kev coj ncaj ncees nrog lub tswv yim ntawm kev cog qoob loo rau ntim thiab tsis yog rau tib neeg?

PLA cov yeeb yaj kiab yuav ib txwm cuam tshuam lub txee lub neej ntawm cov khoom noj uas tsis zoo. Dab tsi ntau tus neeg tsis pom yog qhov kev tsis sib haum xeeb no. Koj xav tau cov khoom kom degrade lub sijhawm, tab sis koj kuj xav kom koj cov khoom tshiab li sai tau.

Qhov nruab nrab lifespan rau PLA zaj duab xis los ntawm lub sij hawm ntawm kev tsim khoom mus rau zaum kawg siv yuav tsawg li 6 lub hlis. Qhov no txhais tau tias tsuas muaj 6 lub hlis los tsim cov ntim khoom, ntim khoom, muag cov khoom, xa mus rau tom khw thiab rau cov khoom siv. Qhov no yog qhov nyuaj tshwj xeeb tshaj yog rau cov khoom lag luam uas tab tom nrhiav rau cov khoom xa tawm, vim tias PLA yuav tsis muab kev tiv thaiv thiab siv sijhawm ntev.
