Dab tsi yog Kev Taw Qhia Ntawm Kraft Daim Ntawv Rau Kev Nyab Xeeb Ntawm Kev Lag Luam Luam Ntawv?
1. Kev tsim cov khoom ntim khoom noj khoom haus rau tib neeg txoj sia nyob nrog kraft ntawv; Piv txwv li, glutinous nplej ntawv siv rau ntawm cov khoom qab zib ntim thiab pob kws ci ntim khob rau cov dej khov yog cov ntim khoom noj tau zoo. Ntawm cov khoom siv ntim cov yeeb yaj kiab, cov neeg paub tab ntau yog pob tshab, tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom, tawv, thiab roj-resistant films, uas yog edible thiab siv tau rau ntim zaub mov.
2. faib cov ntim ntsuab; (Lub ntim ntsuab muab faib ua A-theem thiab AA-level. A-theem ntsuab ntim yog hais txog cov ntim nruab nrab uas cov khib nyiab tuaj yeem siv tau, rov ua dua lossis degraded, thiab muaj cov tshuaj lom nyob rau hauv cov kev txwv AA-theem ntsuab ntim yog hais txog qhov tsim nyog. ntim cov khoom pov tseg tuaj yeem rov ua dua, rov ua dua lossis degraded, thiab tsis ua rau muaj kev phom sij rau pej xeem rau tib neeg lub cev thiab ib puag ncig thaum lub sijhawm tag nrho lub neej ntawm cov khoom, thiab muaj cov tshuaj lom nyob rau hauv qhov txwv.)
3. Siv cov ntaub ntawv ntsuab rau kev ntim khoom; cov neeg tsim qauv siv tau qee cov ntaub ntawv ntshiab thiab ntuj los txhim kho lub ntim tsim. Piv txwv li, lub tais zoo li lub thawv tsim los ntawm kev siv cov txiv maj phaub plhaub tuaj yeem ua tau zoo tsim rau hauv cov ntim khoom noj.
4. Kraft daim ntawv tsim cov ntawv ntim; Cov ntaub ntawv raw ntawm daim ntawv yog cov nroj tsuag fiber ntau, uas yuav tsis ua phem rau ib puag ncig, thiab tseem tuaj yeem rov ua dua tshiab rau papermaking. Tsis tas li ntawd, ntxiv rau qhov zoo ntawm lub teeb yuag, tus nqi qis, thiab kev poob siab tsis kam, cov khoom siv pulp molded kuj muaj cov huab cua zoo permeability, uas yog qhov zoo rau kev khaws cov khoom tshiab. Nyob rau hauv cov nqe lus ntawm kev khiav dej num thoob ntiaj teb cov khoom lag luam, lawv tau siv dav hauv cov qe, txiv hmab txiv ntoo, iav, thiab lwm yam. Ntawm cov khoom ntim cov khoom lag luam uas tsis muaj zog, yooj yim tawg, thiab cov khoom uas ntshai tsam raug nyem.
