Nrog rau kev paub txog kev tiv thaiv ib puag ncig, muaj kev xav tau ntau ntxiv rau cov khoom ntim biodegradable.Biodegradable composite hnab tau siv dav hauv kev lag luam ntim hauv xyoo tas los no vim lawv cov yam ntxwv zoo xws li tus nqi qis, siab zog, thiab biodegradability.
Cov khoom siv ntawm biodegradable composite hnab feem ntau yog sib xyaw ntawm ntau yam biodegradable polymers, xws li polyethylene (PE), polypropylene (PP), polylactic acid (PLA), thiab hmoov txhuv nplej siab, ua ke nrog qee cov additives.Cov ntaub ntawv no feem ntau ua ke los ntawm kev sib xyaw ua ke, tshuab zaj duab xis, lossis cov txheej txheem casting los ua ib qho kev sib xyaw ntawm ob lossis ntau txheej nrog cov khoom sib txawv.
Cov txheej sab hauv ntawm lub hnab biodegradable composite feem ntau yog ua los ntawm biodegradable polymer, xws li PLA lossis hmoov txhuv nplej siab, uas muab lub hnab nrog biodegradability.Cov txheej txheem nruab nrab yog tsim los ntawm kev sib xyaw biodegradable polymer thiab cov khoom siv polymer, xws li PE lossis PP, txhawm rau txhim kho lub zog thiab ruaj khov ntawm lub hnab.Cov txheej txheej sab nrauv kuj yog ua los ntawm cov khoom siv polymer, muab cov khoom thaiv zoo thiab txhim kho kev luam ntawv zoo ntawm lub hnab.
Nyob rau hauv xyoo tas los no, kev tshawb fawb tau tsom mus rau txoj kev loj hlob ntawm high-performance biodegradable composite hnab nrog zoo heev mechanical thiab barrier zog.Kev siv nanotechnology, xws li kev koom ua ke ntawm nano-av nplaum los yog nano-fillers, tau pom tias yuav txhim kho lub zog, toughness, thiab barrier zog ntawm biodegradable composite hnab.
Tsis tas li ntawd, cov qauv hauv kev lag luam ntim khoom yog los ntawm kev siv cov khoom siv ruaj khov thiab txuas ntxiv dua tshiab, xws li biomass-based bioplastics, hauv kev tsim cov hnab ntim biodegradable.Qhov no tau ua rau kev txhim kho cov khoom siv biodegradable tshiab, xws li polyhydroxyalkanoates (PHA), uas tau los ntawm cov kab mob fermentation ntawm cov khoom siv txuas ntxiv dua tshiab thiab muaj biodegradability zoo heev thiab txhua yam khoom.
Degradable composite ntim hnab tau dhau los ua neeg nyiam ntau dua li cov neeg paub txog kev tiv thaiv ib puag ncig tau raug txhim kho tas li.Cov hnab ntim khoom sib xyaw yog ib hom ntim khoom uas yog ua los ntawm ob lossis ntau cov ntaub ntawv los ntawm cov txheej txheem sib xyaw.Lawv muaj kev ua tau zoo dua li kev ntim khoom ib leeg thiab tuaj yeem daws cov teeb meem ntawm kev khaws cia, kev thauj mus los, thiab kev lag luam ntawm cov khoom noj thiab lwm yam khoom.
Txawm li cas los xij, cov hnab ntim khoom sib xyaw ua ke tau raug thuam rau lawv qhov tsis zoo rau ib puag ncig.Nyob rau hauv xyoo tas los no, nrog rau kev xav tau ntau ntxiv rau kev txhim kho kom ruaj khov, ntau thiab ntau cov kev xav tau them rau qhov teeb meem ntawm "dawb paug" tshwm sim los ntawm cov pov tseg yas.Txhawm rau ua kom tau raws li cov kev cai ntawm kev tiv thaiv ib puag ncig thiab txhawb kev txhim kho kom ruaj khov, kev tshawb fawb rau hauv cov hnab ntim khoom degradable tau dhau los ua lub ntsiab lus kub.
Degradable composite hnab ntim khoom yog ib qho kev xaiv zoo tshaj plaws, vim tias lawv tuaj yeem txo qhov kev puas tsuaj ntawm cov pov tseg yas rau ib puag ncig.
Lub hnab ntim khoom degradable yog tsim los ntawm cov hmoov txhuv nplej siab thiab lwm yam khoom siv ntuj tsim, uas ua rau nws biodegradable nyob rau lub sijhawm luv luv.Nws tuaj yeem muaj kev nyab xeeb thiab yooj yim decomposed rau hauv carbon dioxide thiab dej, tsis ua rau muaj kev puas tsuaj rau ib puag ncig.
Lub hnab ntim khoom degradable muaj cov khoom zoo rau kev ntim khoom, nrog rau cov dej noo zoo, siab zog, thiab zoo toughness.Nws tuaj yeem tiv thaiv cov khoom los ntawm ya raws, huab cua, thiab teeb pom kev zoo, thiab ua tiav cov txiaj ntsig zoo ib yam li cov hnab ntim khoom yas.
Tsis tas li ntawd, lub hnab ntim khoom degradable tuaj yeem raug kho raws li cov neeg siv khoom sib txawv.Nws tuaj yeem ua rau ntau qhov ntau thiab tsawg, qauv, thiab xim, thiab tuaj yeem luam tawm nrog kev tshaj tawm lossis cov ntaub ntawv tshaj tawm.
Kev siv cov hnab ntim khoom sib xyaw ua kom tsis zoo tuaj yeem pab txo cov khoom pov tseg yas thiab txhawb kev txhim kho kom ruaj khov.Nws tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv khoom ntim khoom thaum tseem tiv thaiv thiab txhim kho ib puag ncig.
Cov yam ntxwv ntawm biodegradable composite hnab feem ntau suav nrog cov hauv qab no:
1. biodegradable: biodegradable composite hnab yog tsim los ntawm cov khoom siv ntuj tsim, xws li cov hmoov txhuv nplej siab, cellulose, thiab lwm yam, kom lawv tuaj yeem biodegraded nyob rau hauv ib puag ncig ntuj thiab yuav tsis ua paug rau ib puag ncig.
2. Zoo noo noo tsis kam: biodegradable composite hnab tuaj yeem npog nrog cov ntaub ntawv noo noo nyob rau hauv txheej sab hauv, uas tuaj yeem tiv thaiv kom tsis txhob ya raws hauv cov khoom uas muaj dej noo.
3. siab zog, zoo toughness: biodegradable composite hnab muaj siab tensile zog thiab toughness, ua rau lawv muaj peev xwm tiv taus hnyav loads.
4. Customizable thiab nplua nuj ntau haiv neeg: biodegradable composite hnab tuaj yeem ua rau ntau qhov sib txawv, xim, qauv thiab luam ntawv raws li cov neeg siv khoom xav tau kom tau raws li kev xav tau ntawm kev lag luam sib txawv.
5.Can hloov cov hnab yas ib txwm: piv nrog cov hnab yas ib txwm siv, cov hnab ntim khoom siv biodegradable muaj kev tiv thaiv ib puag ncig zoo dua, degradability thiab rov ua dua tshiab, cov khoom ntim zoo dua qub.
Hauv cov ntsiab lus, kev txhim kho cov hnab ntim khoom sib xyaw degradable yog ib qho kev ntsuas tseem ceeb los txhawb txoj kev loj hlob ntawm kev lag luam ntim khoom.Kev siv cov khoom siv degradable hauv cov hnab ntim khoom sib xyaw tuaj yeem txo qhov kev puas tsuaj los ntawm cov pov tseg yas rau ib puag ncig, thiab nws muab kev daws teeb meem rau ib puag ncig rau qhov teeb meem ntawm "dawb paug".Txawm hais tias cov hnab no raug nqi ntau dua, cov txiaj ntsig uas lawv coj mus rau ib puag ncig yog nyob deb.Raws li cov neeg siv khoom txuas ntxiv txhim kho lawv txoj kev paub txog kev tiv thaiv ib puag ncig, kev ua lag luam kev cia siab rau cov hnab ntim khoom sib xyaw degradable yuav ua tau zoo dua.
