Nyob rau hauv lub era ntawm ib puag ncig kev nco qab, qhov kev tshawb nrhiav rau kev hloov pauv mus rau cov khoom siv niaj hnub tau coj mus rau qhov nce ntawm biodegradable films. Cov ntaub ntawv tshiab no cog lus rau yav tom ntej uas ntim thiab lwm yam kev siv yeeb yaj kiab tsis yog tsuas yog ua haujlwm xwb tab sis kuj yog eco-friendly. Hauv tsab xov xwm no, peb yuav delve rau hauv cov txheej txheem tsim cov yeeb yaj kiab biodegradable, tshawb txog cov kev tshawb fawb tom qab lawv cov kev tsim thiab lawv qhov kawg degradation, kom ntseeg tau tias qhov chaw ib puag ncig tsawg.
Cov khoom xyaw ntawm Biodegradable Films:
Cov yeeb yaj kiab biodegradable feem ntau yog tsim los ntawm cov khoom siv txuas ntxiv dua tshiab xws li pob kws hmoov txhuv nplej siab, cellulose, lossis lwm yam khoom siv cog. Cov khoom siv raw no raug xaiv rau lawv lub peev xwm los ua kom tawg raws li lub sijhawm, tsis muaj kev puas tsuaj rau residues.
Txheej txheem ntau lawm:
ib. Extraction: Cov txheej txheem pib nrog kev rho tawm cov ntaub ntawv hauv paus los ntawm cov nroj tsuag. Qhov no suav nrog cov txheej txheem kev siv tshuab thiab tshuaj lom neeg los cais cov yam xav tau. b. Polymerization: Cov ntaub ntawv rho tawm yog tom qab ntawd polymerized los ua cov saw ntev ntawm cov molecules, uas muab cov yeeb yaj kiab nws lub zog thiab yoog raws. c. Zaj duab xis Casting: Lub polymer yog melted thiab kis mus rau hauv ib txheej nyias, uas yog ces txias thiab solidified los ua cov zaj duab xis. Cov kauj ruam no yuav tsum muaj qhov kub thiab txias thiab ceev tswj kom ntseeg tau tias qhov sib xws thiab zoo. d. Kev Kho Mob: Cov yeeb yaj kiab yuav raug kho ntau yam, xws li txheej nrog cov khoom siv ntxiv los txhim kho nws cov khoom, xws li dej tsis kam lossis tiv thaiv UV.
Lub luag haujlwm ntawm Additives:
Cov additives ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov yeeb yaj kiab biodegradable. Lawv tuaj yeem txhim kho cov yeeb yaj kiab cov khoom thaiv, cov khoom siv dag zog, thiab kev ua haujlwm. Txawm li cas los xij, nws yog ib qho tseem ceeb los xyuas kom meej tias cov additives no kuj biodegradable los tswj cov yeeb yaj kiab hauv eco-friendliness.
Kev Tswjhwm Zoo: Txhua theem ntawm kev tsim khoom yog raug rau kev tswj xyuas nruj. Qhov no suav nrog kev sim rau cov thickness, lub zog, thiab biodegradation tus nqi kom ntseeg tau tias cov yeeb yaj kiab ua tau raws li cov qauv xav tau.
Ntim thiab Kev faib tawm: Thaum cov yeeb yaj kiab raug tsim thiab kuaj xyuas zoo, nws tau ntim rau hauv txoj hauv kev uas txo nws qhov cuam tshuam ib puag ncig. Qhov no feem ntau suav nrog kev siv cov khoom ntim tsawg kawg nkaus thiab xaiv cov ntim khoom siv rov ua dua lossis rov ua dua tshiab.
Cov txheej txheem degradation: Qhov kev sim tseeb ntawm cov yeeb yaj kiab biodegradable yog nws lub peev xwm degrade. Cov txheej txheem no tau yooj yim los ntawm cov kab mob uas ua rau cov yeeb yaj kiab polymers rau hauv dej, carbon dioxide, thiab biomass. Tus nqi ntawm degradation tuaj yeem cuam tshuam los ntawm yam xws li zaj duab xis muaj pes tsawg leeg, ib puag ncig, thiab muaj cov kab mob tshwj xeeb.
Lub neej yav tom ntej ntawm Biodegradable Films: Raws li kev siv thev naus laus zis, yog li muaj peev xwm rau biodegradable films. Cov kws tshawb fawb txuas ntxiv ua haujlwm los txhim kho lawv cov kev ua tau zoo thiab txo lawv cov nqi, ua rau lawv muaj txiaj ntsig zoo dua rau cov khoom siv yas.
Kev tsim cov yeeb yaj kiab biodegradable yog txheej txheem nyuaj uas yuav tsum muaj qhov sib npaug ntawm kev tshawb fawb thiab kev ruaj khov. Raws li peb txav mus rau lub neej yav tom ntej, cov yeeb yaj kiab no muaj kev cog lus rau kev daws teeb meem ntawm cov pov tseg yas. Los ntawm kev nkag siab txog lawv cov kev tsim khoom thiab kev degradation, peb tuaj yeem txaus siab rau qhov kev siv zog los tsim lub ntiaj teb tus phooj ywg zoo dua.
Nco ntsoov, txhua qhov kev xaiv peb ua, los ntawm cov khoom peb yuav mus rau cov ntaub ntawv uas peb siv, pab txhawb kev noj qab haus huv ntawm peb lub ntiaj teb. Cia peb muab cov yeeb yaj kiab biodegradable ua ib kauj ruam ntawm kev huv, ntsuab tag kis.
