Cov khoom ntim khoom noj uas ua los ntawm cov ntaub ntawv siv tau ntau zuj zus vim tias lawv cov yam ntxwv muaj kev nyab xeeb thiab lwm txoj hauv kev zoo. Txawm li cas los xij, txhawm rau kom muaj kev noj qab haus huv thiab kev nyab xeeb, muaj qee cov qauv uas yuav tsum tau ua raws li cov ntaub ntawv siv los tsim cov ntim khoom noj. Ntim yog ib qho tseem ceeb uas cuam tshuam rau qhov zoo thiab saj ntawm cov zaub mov sab hauv. Yog li ntawd, cov khoom ntim khoom noj yuav tsum tau kuaj xyuas txhua yam, thiab lawv yuav tsum ua raws li cov qauv hauv qab no.
1. Cov khoom siv ntawv yog tsim los ntawm cov khoom siv huv huv
Cov ntaub ntawv siv hauv kev tsim cov ntawv tais zaub mov, khob ntawv, lub thawv ntawv, thiab lwm yam ntim khoom yuav tsum ua tau raws li Ministry of Health cov lus qhia tshwj xeeb rau cov ntsiab lus thiab muaj pes tsawg leeg ntawm cov txheej txheem tsim khoom. Yog li ntawd, cov tuam txhab lag luam yuav tsum siv cov ntaub ntawv ua los ntawm cov khoom siv huv huv uas ua tau raws li cov qauv kev noj qab haus huv thiab kev nyab xeeb, tsis txhob cuam tshuam rau cov xim, aroma, lossis saj ntawm cov zaub mov, thiab muab kev tiv thaiv zoo rau cov neeg siv khoom.
Tsis tas li ntawd, cov ntaub ntawv siv rov ua dua tshiab yuav tsum tsis txhob siv rau hauv cov khoom uas nkag mus rau hauv cov khoom noj. Vim tias daim ntawv no yog tsim los ntawm cov ntawv siv dua tshiab, nws dhau los ntawm deinking, bleaching, thiab whitening txheej txheem thiab tej zaum yuav muaj co toxins uas yooj yim tso rau hauv cov zaub mov. Yog li ntawd, feem ntau cov tais ntawv thiab khob dej yog ua los ntawm 100% ntshiab kraft ntawv los yog 100% ntshiab PO pulp.
2. FDA ua raws thiab tsis ua rau cov zaub mov
Cov ntaub ntawv siv los ua zaub mov yuav tsum ua raws li cov hauv qab no: kev nyab xeeb thiab kev nyiam huv, tsis muaj tshuaj lom, tsis muaj cov khoom hloov pauv, thiab tsis muaj kev cuam tshuam nrog cov khoom noj uas lawv muaj. Qhov no yog ib qho kev ntsuas tseem ceeb sib npaug uas txiav txim siab tus neeg siv kev noj qab haus huv. Vim tias cov ntawv ntim khoom noj muaj ntau haiv neeg, txhua yam ntawm cov tais diav (dej noodles, kua zaub, kas fes kub) rau cov khoom noj qhuav (khoom qab zib, khoom qab zib, pizza, mov) sib raug rau daim ntawv, kom ntseeg tau tias daim ntawv tsis cuam tshuam los ntawm chav lossis kub.
Hardness, haum daim ntawv hnyav (GSM), compression kuj, tensile zog, tawg tsis kam, dej nqus, ISO whiteness, ya raws tsis kam ntawm daim ntawv, tshav kub kub, thiab lwm yam yuav tsum tau ua raws li los ntawm cov zaub mov ntawv. Tsis tas li ntawd, cov tshuaj ntxiv ntxiv rau cov khoom ntim khoom noj yuav tsum yog cov hauv paus ntsiab lus meej thiab ua tau raws li Ministry of Health cov cai. Txhawm rau kom ntseeg tau tias tsis muaj cov kab mob toxicity cuam tshuam rau qhov zoo thiab kev nyab xeeb ntawm cov zaub mov muaj, tus qauv sib xyaw yog siv.
3. Daim ntawv uas muaj lub siab ntev thiab ceev decomposition nyob rau hauv ib puag ncig
Txhawm rau kom tsis txhob muaj dej xau thaum siv lossis khaws cia, xaiv cov khoom ua los ntawm cov ntawv zoo uas muaj cov cua sov tiv taus thiab impermeable. Txhawm rau tiv thaiv ib puag ncig, cov ntaub ntawv siv los khaws cov zaub mov yuav tsum ua kom tau raws li cov txheej txheem kom yooj yim ntawm degradability thiab kev txwv pov tseg. Piv txwv li, lub tais zaub mov thiab mugs, yuav tsum tau ua los ntawm ntuj PO lossis kraft pulp uas decomposes hauv 2-3 lub hlis. Lawv tuaj yeem decompose nyob rau hauv qhov kub thiab txias, cov kab mob, thiab cov av noo, piv txwv li, tsis muaj kev puas tsuaj rau av, dej, lossis lwm yam khoom muaj sia.
4. Cov ntaub ntawv ntawv yuav tsum muaj cov tshuaj tua kab mob zoo
Thaum kawg, daim ntawv siv rau ntim yuav tsum muaj peev xwm khaws cia thiab tiv thaiv cov khoom hauv. Qhov no yog lub luag haujlwm tseem ceeb uas txhua lub tuam txhab yuav tsum xyuas kom meej thaum tsim cov ntim khoom.
Qhov no yog vim qhov tseeb tias cov khoom noj yog qhov tseem ceeb ntawm kev noj haus thiab lub zog rau tib neeg. Txawm li cas los xij, lawv muaj kev cuam tshuam rau lwm yam xws li kab mob, kub, huab cua, thiab lub teeb, uas tuaj yeem hloov qhov tsw thiab ua rau lwj. Cov neeg tsim khoom yuav tsum ua tib zoo xaiv hom ntawv siv los ua lub ntim kom ntseeg tau tias cov khoom noj hauv tsev yog khaws cia zoo tshaj plaws los ntawm lwm yam. Daim ntawv yuav tsum yog lub hauv paus muaj zog thiab tawv txaus los tuav cov zaub mov tsis tas yuav muag, tsis muaj zog, los yog kua muag.
