Puas yog Eco-phooj ywg tiag tiag kom Degrade Eco-friendly Hnab?

Tam sim no, cov khoom siv raw rau kev tsim cov hnab degradable ntawm kev ua lag luam feem ntau yog PLA thiab PBAT, thiab feem ntau yog ib qho khoom siv tsis ncaj qha los tsim cov hnab degradable. Tab sis hnub no, peb yuav tham txog qhov chaw, tshuaj lom neeg, thiab cov nqi lag luam ntawm polylactic acid (PLA).

Polylactic acid (PLA) yog ib yam khoom siv biodegradable hnab uas tuaj yeem degraded los ntawm cov kab mob uas siv cov hmoov txhuv nplej siab los ua raw khoom thiab siv cov tshuab microbial fermentation engineering. Cov khoom degradable no muaj cov khoom tshwj xeeb xws li ua tiav biodegradability, biocompatibility, hydrophobicity, zoo impermeability, piezoelectricity, nonlinear optical kev ua, thiab lwm yam, thiab yog ua los ntawm thermoplastic processability nrog petrochemical resins. PLA degradable cov ntaub ntawv tuaj yeem siv rau hauv kev txhaj tshuaj molding, extrusion tshuab zaj duab xis, extrusion casting, extrusion hollow molding, compression molding thiab lwm yam txheej txheem rau kev ua, manufacturing molded khoom, films, ntim; Nws tuaj yeem ua ke nrog lwm cov ntaub ntawv. PLA biodegradable cov ntaub ntawv yog siv nyob rau hauv ntau daim ntawv thov teb xws li advanced ntim khoom, sustained-tso tshuaj cov ntaub ntawv uas yuav absorbed los ntawm tib neeg lub cev, implantable biomaterials thiab lwm yam ntim, kev kho mob thiab kev noj qab haus huv, ua liaj ua teb zaj duab xis thiab hais txog.

Polylactic acid yog ib qho ntawm cov khoom tseem ceeb ntawm cov organic teeb meem hauv cov kab mob, thiab nws kuj yog ib qho khoom noj rau cov kab mob, uas tuaj yeem decomposed rau hauv lub zog los ntawm decomposition enzymes hauv cov kab mob thaum cov kab mob nkag mus rau hauv lub xeev ntawm kev tshaib kev nqhis, uas yog sib npaug rau tsiaj rog.

Tam sim no, kev tshawb fawb cov ntsiab lus ntawm polylactic acid feem ntau suav nrog ob qho kev qhia loj.

1. Kev tshawb fawb txog kev siv thev naus laus zis los txo cov nqi tshuaj lom neeg ntawm polylactic acid thiab txhim kho kev ua haujlwm. Piv txwv li, cov kab mob genetic engineered thiab genetic hloov cov nroj tsuag yog siv los tsim polylactate. Nws raug hloov kho los ntawm kev sib xyaw nrog lwm cov ntaub ntawv biodegradable los txhim kho nws cov khoom.

2. Kev tshawb fawb txog kev sib xyaw ua ke thiab cov txheej txheem ntawm nruab nrab thiab ntev saw polylactic acid nrog cov pab pawg tshwj xeeb xws li vinyl, cyano, phenyl, F, Cl, thiab lwm yam.

Los ntawm cov lus piav qhia saum toj no, nws tuaj yeem txiav txim siab tias ntev npaum li lub hnab ntim khoom yog ua los ntawm cov khoom siv degradable tiag tiag, nws yuav tsum yog tus phooj ywg ib puag ncig thiab yuav tsis ua rau muaj kuab paug rau ib puag ncig ntuj.
