Nrog kev txhim kho ntawm kev paub txog ib puag ncig, tib neeg qhov kev xav tau cov khoom siv zoo rau ib puag ncig thiab lawv cov khoom lag luam kuj nce ntxiv. Cov khoom siv compostable PLA thiab PLA compostable hnab ntim khoom tau maj mam siv dav hauv kev ua lag luam.
Polylactic acid, tseem hu ua PLA (Polylactic Acid), yog ib qho polymer tau los ntawm kev polymerizing lactic acid ua cov khoom siv raw tseem ceeb. Cov khoom siv raw yog los ntawm pob kws, cassava, thiab lwm yam. Cov txheej txheem tsim khoom ntawm PLA tsis muaj kuab paug, thiab cov khoom tuaj yeem biodegradable thiab rov ua dua tshiab hauv xwm.
Cov txiaj ntsig ntawm PLA
1. Kev puas tsuaj ntawm cov khoom siv hauv lub cev: Tom qab PLA raug pov tseg, nws tuaj yeem raug puas tsuaj tag nrho rau hauv dej thiab carbon dioxide nyob rau hauv cov xwm txheej tshwj xeeb, thiab rov qab nkag mus rau hauv kev ncig ntuj, zam kev ua qias tuaj rau ib puag ncig ntev los ntawm cov yas ib txwm muaj.
2. Cov peev txheej rov ua dua tshiab: PLA feem ntau yog polymerized los ntawm lactic acid rho tawm los ntawm cov hmoov txhuv nplej siab, qab zib thiab lwm yam qoob loo, uas yog cov peev txheej rov ua dua tshiab, thiab txo qhov kev vam khom rau cov peev txheej roj av.
3. Nws muaj huab cua zoo permeability, oxygen permeability thiab carbon dioxide permeability, nws kuj muaj cov khoom ntawm kev cais cov ntxhiab tsw. Cov kab mob thiab pwm feem ntau lo rau ntawm qhov chaw ntawm cov yas biodegradable, yog li muaj kev txhawj xeeb txog kev nyab xeeb thiab kev tu cev. Txawm li cas los xij, PLA yog tib lub yas biodegradable nrog cov khoom zoo heev tiv thaiv kab mob thiab tiv thaiv pwm.
Txoj kev puas tsuaj ntawm PLA
1. Hydrolysis: Pawg ester ntawm cov saw hlau tseem ceeb tawg, yog li txo qhov hnyav molecular.
2. Kev rhuav tshem cua sov: ib qho xwm txheej nyuaj uas ua rau muaj ntau yam sib xyaw ua ke, xws li cov molecule sib dua thiab cov oligomers linear thiab cyclic nrog cov qhov hnyav molecular sib txawv, nrog rau lactide.
3. Kev puas tsuaj ntawm cov duab: Kev tawg ntawm ultraviolet tuaj yeem ua rau puas tsuaj. Qhov no yog ib qho tseem ceeb uas ua rau PLA raug tshav ntuj hauv cov yas, cov thawv ntim khoom, thiab cov ntawv thov zaj duab xis.
Daim ntawv thov ntawm PLA hauv daim teb ntim khoom
Cov ntaub ntawv PLA siv rau ntau qhov chaw. Hauv kev lag luam ntim khoom, zaj duab xis PLA feem ntau yog siv rau hauv cov ntim khoom noj, dej haus thiab tshuaj los hloov cov ntim yas ib txwm muaj, txhawm rau ua tiav lub hom phiaj ntawm kev tiv thaiv ib puag ncig thiab kev ruaj khov.
PACK MIC tshwj xeeb hauv kev tsim cov hnab yas uas siv tau dua tshiab thiab cov hnab yas uas lwj tau.
