Cov hnab ntim khoom tawg yooj yim, qhov cuam tshuam yog tias lawv tuaj yeem ua rau tsis zoo, tab sis cov hnab ntim qis tsis zoo tau muab faib ua" degradable" thiab" tag nrho cov kev cuam tshuam" ;. Lub hnab ntim degradable yog hais txog qhov sib ntxiv ntawm qee qhov nqi ntxiv (xws li cov hmoov txhuv nplej siab, hloov pauv cov hmoov txhuv nplej siab lossis lwm cov cellulose, photosensitizer, biodegradation tus neeg sawv cev, thiab lwm yam) hauv cov txheej txheem ntau lawm kom txo nws txoj kev ruaj khov, thiab tom qab ntawd nws yuav yooj yim rau hauv ntuj puag ncig Degradable yas ntim hnab. Siab ntim cov hnab ntim khoom txhais tau tias txhua lub hnab yas ntim khoom pov tseg rau hauv dej thiab carbon dioxide. Lub hauv paus tseem ceeb ntawm cov khoom siv zoo no yog ua tiav los ntawm pob kws, qos ntoo, thiab lwm yam rau hauv cov kab mob lactic acid, uas yog PLA.
Polylactic acid (PLA) yog ib hom tshiab ntawm cov khoom siv roj ntsha thiab cov khoom siv hloov dua tshiab. Cov hmoov txhuv nplej siab cov khoom siv yog saccharified kom tau txais cov piam thaj, uas tom qab ntawd fermented los ntawm cov piam thaj thiab qee yam kab mob kom tsim cov siab-lity acid lactic acid, thiab tom qab ntawd ua ke los ntawm cov tshuaj lom neeg. Polylactic acid ntawm lub cev hnyav. Nws muaj biodegradability zoo. Tom qab siv, nws tuaj yeem ua kom puas tsuaj los ntawm cov kab mob me me nyob rau hauv cov xwm txheej tshwj xeeb, thiab nws thiaj li tsim cov pa roj carbon dioxide thiab dej, uas tsis ua paug rau ib puag ncig. Qhov no tau txais txiaj ntsig ntau ib puag ncig thiab yog ib puag ncig zoo rau cov neeg ua haujlwm.
Tam sim no, cov khoom siv xyoob ntoo tseem ceeb ntawm cov khoom siv ntim cov khoom ntim tau zoo yog tsim ntawm PLA + PBAT, uas tuaj yeem muab pov tseg tag nrho rau hauv dej thiab cov pa roj carbon dioxide nyob rau hauv 3-6 lub hlis raws li cov zwj ceeb (60-70 degrees) ), tsis muaj kuab paug rau ib puag ncig. Vim li cas koj thiaj yuav tsum tsim PBAT ntxiv? Kev hloov ntim cov chaw tsim khoom lag luam qhia thiab piav qhia tias PBAT yog kev siv tshuaj ntawm adipic acid, 1,4-butanediol thiab terephthalic acid. Nws yog cov roj ntsha hluavtaws cov roj uas tuaj yeem ua tau dhau ntawm biodegradable Group-aromatic polymer, PBAT muaj qhov hloov tau zoo, thiab tuaj yeem siv rau zaj duab xis extrusion, tshuab ua, txheej txheej extrusion thiab lwm cov txheej txheem molding. Lub hom phiaj ntawm kev sib xyaw ua ke PLA thiab PBAT yog txhawm rau txhim kho qhov tawv, kev hloov pauv, thiab kev ua haujlwm ntawm PLA. PLA thiab PBAT tsis sib haum, yog li xaiv qhov haum qhov tsim nyog tuaj yeem txhim kho kev ua tau zoo ntawm PLA.
Peb muab patented puv biodegradable zaj duab xis thiab lub hnab PVA, tag nrho cov khoom yog tsim los ntawm cov cuab yeej siv casting, Nws txawv ntawm cov tshuab moulding khoom, tag nrho cov tshuab moulding khoom tsis puv biodegradable. Peb tuaj yeem tsim pva zaj duab xis thiab hnab hauv pob tshab thiab pob tshab xim. thiab PVA zaj duab xis yog du ntau dua li cov tsoos tshuab moulding khoom.
peb kuj muab cov khoom siv organic puv biodegradable zaj duab xis thiab hnab nrog cov khoom muaj ntawv pov thawj muaj txheej txheem thiab cov txheej txheem.
