Ntawm cov khoom ntim ntau,ntawv ntim yog ntau nyob rau hauv txoj kab nrog cov kev xav tau ntawm cov niaj hnub ntsuab thiab qis-carbon. Nws cov yam ntxwv ntawm cov khoom siv kuj ua rau nws muaj peev xwm siv tau ntau zaus, ua rau muaj kev cuam tshuam tsawg dua ntawm ib puag ncig thaum nws muab pov tseg, thiab tib lub sijhawm, nws muaj qhov zoo li plasticity.
Cov ntawv ntim ntawv muaj qhov zoo hauv qab no:
1. Cov txiaj ntsig zoo: Cov ntawv ntim nrog nws cov khoom siv tshwj xeeb, qee cov ntawv ua haujlwm tom qab ua tiav (xws lizaub mov qib boardFVO,GCU , thiab lwm yam.) Lub toughness kuj ua rau lub pob tsis tshua muaj kev tawg. Piv nrog rau kev ntim khoom ntawm lwm cov ntaub ntawv, cov ntawv ntim ntawv muaj ntau chav ua si hauv kev tsim cov duab thiab cov duab, thiaj li ua tau raws li qhov xav tau ntawm ntau hom kev lag luam rau ntim.
2. Ib puag ncig zoo: Cov khoom siv tseem ceeb ntawm cov ntawv ntim yog cov nroj tsuag fiber ntau, thiab cov nroj tsuag yog cov khoom siv txuas ntxiv dua tshiab. Nws tuaj yeem pom tau tias daim ntawv ntim ntau dua nyob rau hauv txoj kab nrog cov kev xav tau ntawm kev txhim kho kom ruaj khov vim nws yog ib txwm degraded.
3. Kev ua lag luam kom zoo dua: Cov nqi tsim khoom ntawm cov ntawv ntim khoom tsawg. Feem ntau hais lus, cov tuam ntxhab tuaj yeem ua cov khoom loj loj nrog cov cuab yeej siv tshuab yooj yim. Piv nrog rau lwm lub ntim, cov khoom siv tau qis dua, thiab cov khoom zoo tuaj yeem lav tau. Vim yog cov ntaub ntawv mos ntawm cov ntawv ntim thiab qee cov khoom yas, qhov zoo ntawm kev yooj yim folding kuj ua rau cov nqi khaws cia thiab kev thauj mus los ntawm cov ntawv ntim qis.
Nrog rau kev xav tau ntau ntxiv rau cov ntawv ntim khoom los ntawm txhua qhov chaw ntawm lub neej nyob rau hauv xyoo tas los no, cov kev xav tau ntawm cov ntaub ntawv hais txog cov ntaub ntawv kuj tau nce siab thiab siab dua, tsis tsuas yog xav tau cov ntawv ntim ntau dua, tab sis kuj txo qis cov gram hnyav thiab ntau lub zog. Txhim kho kev siv cov peev txheej txuas ntxiv dua tshiab, tsim cov ntim khoom tshiab, thiab hloov lwm cov khoom siv uas siv cov peev txheej ntau dua. Thaum pib ntawm lub xyoo pua 20th, lub teb chaws thoob plaws ntiaj teb tau pib tawm tsam kev siv cov khoom siv ntawv los hloov cov khoom yas, tab sis tsis ntev tom qab kev siv lub tswv yim no, nws tau pom tias txoj kev siv cov ntaub ntawv no siv cov khoom siv ntoo ntau heev. Kev siv thev naus laus zis ntawm cov nplej straw, bagasse, reed, thiab lwm yam nroj tsuag tau siv, thiab cov pov tseg ntawm hav zoov tau raug txo kom tsawg los ntawm kev nce ntau yam khoom raw.
Daim ntawv qhwv tshwj xeeb yuav raug siv los ntim cov khoom uas muaj kev xav tau tshwj xeeb thiab siv tshwj xeeb. Piv txwv li, biodegradablePLA coated ntawv, tsis tshua muaj hnyav siab tuab siab xoob wrapping ntawv, siv rau ntim khoom noj,roj ntawv pov thawj siv rau ntim khoom noj. Tsis tas li ntawd, nano ntim ntawv, thermal rwb thaiv tsev ntim ntawv, ntawv ua npuas ncauj, thiab lwm yam kuj tseem maj mam siv. Nws ntseeg tau tias nyob rau yav tom ntej, qhov kev thov rau cov ntawv ntim tshwj xeeb no yuav nce exponentially.
