Nrog rau kev txhim kho ntawm ib puag ncig kev paub, tib neeg qhov kev thov rau ib puag ncig tus phooj ywg cov ntaub ntawv thiab lawv cov khoom kuj nce ntxiv. Compostable khoom PLA thiab PLA compostable ntim hnab yog maj mam siv nyob rau hauv kev ua lag luam.
Polylactic acid, tseem hu ua PLA (Polylactic Acid), yog ib qho polymer tau los ntawm polymerizing lactic acid ua cov khoom siv tseem ceeb. Lub hauv paus ntawm cov khoom siv raw yog txaus los ntawm pob kws, cassava, thiab lwm yam..Cov txheej txheem ntawm PLA yog tsis muaj kuab paug, thiab cov khoom tuaj yeem biodegraded thiab rov ua dua tshiab.
Qhov zoo ntawm PLA
1.Biodegradability: Tom qab PLA raug muab pov tseg, nws tuaj yeem degraded tag nrho rau hauv dej thiab carbon dioxide nyob rau hauv tej yam kev mob, thiab rov qab mus rau lub ntuj ncig, zam lub sij hawm ntev ua paug rau ib puag ncig los ntawm cov tsoos plastics.
2.Renewable resources: PLA yog mas polymerized los ntawm lactic acid muab rho tawm los ntawm pob kws starch, qab zib thiab lwm yam qoob loo, uas yog tauj dua tshiab peev, thiab txo dependence rau roj av.
3. Nws muaj huab cua zoo permeability, oxygen permeability thiab carbon dioxide permeability, nws kuj muaj cov cuab yeej ntawm kev rho tawm tsw. Cov kab mob thiab cov pwm tuaj yeem ua raws li qhov chaw ntawm biodegradable plastics, yog li muaj kev txhawj xeeb txog kev nyab xeeb thiab kev nyiam huv. Txawm li cas los xij, PLA tsuas yog biodegradable yas uas muaj cov kab mob zoo heev thiab tiv thaiv pwm.
Degradation mechanism ntawm PLA
1.Hydrolysis: Cov ester pawg ntawm cov saw tseem ceeb yog tawg, yog li txo qhov hnyav molecular.
2.Thermal decomposition: ib tug complex phenomenon uas ua rau muaj tshwm sim ntawm txawv tebchaw, xws li sib zog molecules thiab linear thiab cyclic oligomers nrog txawv molecular luj, raws li zoo raws li lactide.
3.Photodegradation: Ultraviolet hluav taws xob tuaj yeem ua rau degradation. Qhov no yog ib qho tseem ceeb ntawm kev raug PLA rau lub hnub ci hauv cov yas, ntim ntim, thiab daim ntawv thov zaj duab xis.
Kev siv PLA hauv kev ntim khoom
Cov ntaub ntawv PLA yog siv rau hauv ntau qhov chaw. Hauv kev lag luam ntim, PLA zaj duab xis feem ntau yog siv rau hauv cov ntim khoom sab nrauv ntawm cov khoom noj, dej haus thiab tshuaj los hloov cov khoom ntim yas, kom ua tiav lub hom phiaj ntawm kev tiv thaiv ib puag ncig thiab ruaj khov.
PACK MIC tshwj xeeb hauv kev tsim cov hnab ntim khoom siv rov ua dua tshiab.
