Kev thov ua lag luam rau cov khoom siv uas tsis ua rau ib puag ncig puas tsuaj nce ntxiv
Ua ib hom khoom siv bio-based degradable tshiab, qhov tshwm sim ntawm cov khoom siv PLA yog qhov tsis ntseeg tias yog ib kauj ruam tseem ceeb hauv kev teb rau lub teb chaws txoj cai tiv thaiv ib puag ncig ntsuab thiab "ob lub hom phiaj carbon". Polylactic acid yog ua los ntawm cov khoom siv rov ua dua tshiab xws li pob kws, cassava, thiab straw. Nws cov yam ntxwv qis-carbon ntsuab ua rau nws sawv cev rau cov khoom siv zoo rau ib puag ncig. Nyob rau hauv xyoo tas los no, nrog lub teb chaws txoj kev saib xyuas rau "kev ua qias tuaj dawb", cov khoom siv degradable xws li PLA tau maj mam suav hais tias yog "tshuaj zoo" los daws cov teeb meem ib puag ncig.
Hauv cov ntsiab lus no, cov tub ntxhais hluas uas feem ntau haus tshuaj yej mis tsis yog neeg txawv rau cov lus "PLA" uas feem ntau pom ntawm cov straws. Raws li ib yam khoom pov tseg, straws tau cuam tshuam loj heev rau kev txhim kho ib puag ncig. Kev txhawb nqa cov ntaub ntawv PLA yog los hloov cov straws roj av ib txwm muaj, uas yog qhov tseem ceeb heev rau kev txo qis kev ua qias tuaj ib puag ncig.
Ib kauj ruam ruaj khov mus rau kev ywj pheej ntawm thev naus laus zis
Hauv kev lag luam, cov thev naus laus zis tsim cov polylactic acid yeej ib txwm raug tswj hwm los ntawm ob peb lub tuam txhab txawv teb chaws, thiab kev txhim kho hauv tsev tau qeeb. Qhov kev tawg ntawm Wuxi Nanda cim qhia txog kev txhim kho maj mam ntawm kuv lub teb chaws lub peev xwm tsim khoom ywj pheej hauv daim teb no. Kev vam khom rau cov txiaj ntsig kev tshawb fawb ntawm pab pawg ntawm Academician Zhang Quanxing ntawm Nanda, lub koom haum tau ua tiav qhov kev tawg loj hauv kev siv tshuab catalyst, thiab txhua yam khoom siv loj, cov txheej txheem thiab cov software tswj hwm tau tsim hauv tsev, rhuav tshem kev vam khom rau cov thev naus laus zis txawv teb chaws thiab ua tiav tag nrho cov chaw hauv zos los ntawm cov khoom siv raw mus rau cov txheej txheem tsim khoom.
Kev siv ntau yam ntawm polylactic acid
Lub peev xwm siv tau zoo ntawm polylactic acid tsis yog tsuas yog nyob rau hauv kev tsim cov khoom siv pov tseg uas tsis ua rau ib puag ncig puas tsuaj xwb, tab sis kuj nyob rau hauv ntau qhov chaw xws li textiles, plastics, ntim khoom, thiab cov yeeb yaj kiab ua liaj ua teb. Nyob ntawm cov xwm txheej polymerization, cov khoom ntawm PLA tsim tawm sib txawv. Qee cov polylactic acid purity siab yog siv rau cov khoom uas xav tau lub zog siab dua, thaum cov polylactic acid purity qis yog tsim rau kev puas tsuaj sai. Qhov kev ywj pheej thiab ntau yam ntxwv tau ua rau PLA txuas ntxiv txhim kho nws txoj haujlwm hauv kev txhim kho kom ruaj khov.
Yav tom ntej, peb tuaj yeem cia siab tias yuav muaj ntau yam khoom siv thev naus laus zis ntsuab los hloov cov khoom siv ib txwm muaj uas ua rau muaj kuab paug thiab ua rau muaj lub neej zoo rau ib puag ncig. Tib lub sijhawm, nrog kev pab los ntawm cov kev tshawb pom tshiab no, kev siv cov peev txheej rov ua dua tshiab ntawm kuv lub teb chaws kuj tseem yuav ua tiav qhov kev dhia zoo hauv ntau qhov chaw.
