V. Qhov zoo ntawm daim ntawv khob
A. Yooj yim nqa thiab siv
Piv nrog rau lwm lub khob, khob ntawv muaj qhov hnyav dua. Lawv yog portable dua. Qhov no ua raudaim ntawv khob lub thawv nyiamrau cov neeg siv khoom haus dej haus thaum tawm mus.
B. Tus kheej tsim thiab hom lag luam
1. Kev kho kom haum
Cov khob ntawv muaj peev xwm ua tau raws li kev cai tsim. Hom thiab cov tub lag luam tuaj yeem hloov kho qhov tsos thiab luam tawm cov ntsiab lus ntawm cov khob ntawv raws li lawv tus kheej xav tau thiab cov duab. Qhov no ua rau cov khob ntawv yog ib qho tseem ceeb rau cov khoom lag luam thiab kev txhawb nqa.
2. Ua kom muaj kev cuam tshuam rau cov khoom lag luam
Cov khob ntawv yog lub thawv ntim khoom siv dav siv. Lawv tau dav siv txhua hnub hauv khw kas fes, khw muag dej haus, thiab lwm qhov chaw. Cov tub lag luam tuaj yeem luam cov cim npe, cov lus tshaj tawm, thiab lwm yam ntawm cov ntawv khob. Qhov no tuaj yeem ua rau lawv cov khoom lag luam nthuav tawm thiab pom kev.
3. Kev nthuav qhia kos duab
Tus tsim ntawm lub khob ntawv tsis yog tsuas yog qhia txog cov duab ntawm lub hom, tab sis kuj yog ib qho nruab nrab rau kev nthuav qhia kos duab. Ntau lub koom haum kab lis kev cai thiab cov kws kos duab siv cov ntawv khob tsim los qhia txog kev muaj tswv yim thiab kev ua yeeb yam. Qhov no tuaj yeem ua rau cov neeg siv khoom muaj txiaj ntsig zoo nkauj thiab kos duab.
C. Cov yam ntxwv ntawm kev tiv thaiv ib puag ncig thiab rov ua dua tshiab
1. Degradability
Cov khob ntawv feem ntau yog ua los ntawm ntuj pulp. Nws yog kev siv thiab rov tsim dua tshiab ntawm cov peev txheej ntuj. Piv nrog rau cov khob yas, cov khob ntawv yog yooj yim rau decompose nyob rau hauv ib puag ncig ntuj. Qhov no txo cov pa phem rau ib puag ncig.
2. Rov ua dua
Cov khob ntawv tuaj yeem siv dua thiab rov siv dua los txo cov peev txheej. Ntau qhov chaw tau teeb tsa cov ntawv khob rov ua dua tshiab thiab ua haujlwm tshwj xeeb thiab rov ua dua tshiab. Qhov no ua rau nws muaj peev xwm rov ua dua cov khob ntawv.
3. Kev txuag hluav taws xob
Kev siv hluav taws xob xav tau rau kev tsim cov khob ntawv yog qhov tsawg. Piv nrog rau lwm lub khob, cov txheej txheem tsim cov khob ntawv siv cov tshuaj tsawg thiab lub zog. Yog li, nws yog ib puag ncig tus phooj ywg ntau dua thiab muaj txiaj ntsig zoo.
Hauv cov ntsiab lus, cov khob ntawv muaj cov yam ntxwv ntawm kev nqa tau yooj yim thiab siv, tus kheej tsim thiab kev lag luam lag luam, nrog rau kev tiv thaiv ib puag ncig thiab rov ua dua tshiab. Raws li lub khob haus dej ntau, cov khob ntawv tuaj yeem ua tau raws li cov neeg siv khoom xav tau. Nyob rau tib lub sijhawm, nws kuj tuaj yeem nqa cov txiaj ntsig zoo ib puag ncig thiab kev lag luam.
