Cov Khoom Siv Raw Feem Ntau Hauv Kev Ua Ntawv: Ib Phau Ntawv Qhia Txog Kev Ua Ntawv

Kev ua ntawv yog ib qho kev lag luam uas muaj keeb kwm ntev uas siv ntau yam khoom siv los tsim cov ntawv uas peb siv txhua hnub. Txij ntoo mus txog ntawv rov ua dua tshiab, txhua yam khoom muaj cov yam ntxwv tshwj xeeb uas cuam tshuam rau qhov zoo thiab kev ua tau zoo ntawm daim ntawv kawg. Hauv phau ntawv qhia no, peb yuav tshawb nrhiav cov khoom siv raw feem ntau hauv kev ua ntawv, lawv cov khoom siv fiber, cov qoob loo ntawm cov pulp, thiab kev siv.

Ntoo: Cov Khoom Siv Tseem Ceeb Ib Txwm Muaj

Ntoo yog ib qho ntawm cov khoom siv raw khoom siv dav tshaj plaws hauv kev ua ntawv, nrog ob pawg tseem ceeb: ntoo mos thiab ntoo tawv.

Ntoo mos

• Qhov Ntev ntawm FiberFeem ntau yog li ntawm 2.5 txog 4.5 hli.
• Cov qoob loo ntawm cov nqaijNruab nrab ntawm 45% thiab 55%.
• Cov yam ntxwvCov ntoo mos mos yog cov fibers ntev thiab yoog tau, ua rau lawv zoo tagnrho rau kev tsim cov ntawv muaj zog. Lawv lub peev xwm los tsim cov interlocks muaj zog ua rau daim ntawv muaj kev ruaj khov zoo heev thiab lub zog tensile. Qhov no ua rau ntoo mos mos yog cov khoom siv raw zoo rau kev tsim cov ntawv sau, ntawv luam ntawv, thiab cov ntaub ntawv ntim khoom muaj zog.

Ntoo tawv

• Qhov Ntev ntawm Fiber: Kwv yees li 1.0 txog 1.7 hli.
• Cov qoob loo ntawm cov nqaijFeem ntau yog 40% txog 50%.
• Cov yam ntxwvCov ntoo tawv luv dua piv rau cov ntoo mos. Txawm hais tias lawv tsim cov ntawv nrog lub zog qis dua, lawv feem ntau sib xyaw nrog cov ntoo mos los tsim cov ntawv luam ntawv nruab nrab mus rau qib qis thiab ntawv so ntswg.

Cov Khoom Siv Ua Liaj Ua Teb thiab Cov Nroj Tsuag

Tsis tas li ntoo xwb, ntau yam khoom siv ua liaj ua teb thiab cov nroj tsuag muaj txiaj ntsig zoo rau kev ua ntawv, muab kev ruaj khov thiab kev siv nyiaj tsim nyog.

Cov Qoob Loo thiab Cov Nplej

• Qhov Ntev ntawm FiberKwv yees li ntawm 1.0 txog 2.0 hli.
• Cov qoob loo ntawm cov nqaij: 30% txog 40%.
• Cov yam ntxwvCov no yog cov khoom siv raw uas muaj ntau thiab pheej yig. Txawm hais tias lawv cov pulp tsis siab heev, lawv tsim nyog rau kev tsim cov ntawv kab lis kev cai thiab cov ntawv ntim khoom.

Xyoob

• Qhov Ntev ntawm Fiber: Ntau yam ntawm 1.5 txog 3.5 hli.
• Cov qoob loo ntawm cov nqaij: 40% txog 50%.
• Cov yam ntxwvCov xyoob fibers muaj cov khoom ze li ntoo, nrog lub zog zoo. Ntxiv mus, xyoob muaj lub voj voog luv luv thiab muaj zog rov ua dua tshiab, ua rau nws yog lwm txoj hauv kev tseem ceeb rau ntoo. Nws tuaj yeem siv los tsim ntau yam ntawv, suav nrog ntawv kab lis kev cai thiab ntawv ntim khoom.

Bagasse

• Qhov Ntev ntawm Fiber: 0.5 txog 2.0 hli.
• Cov qoob loo ntawm cov nqaij: 35% txog 55%.
• Cov yam ntxwvUa ib qho pov tseg ua liaj ua teb, bagasse muaj ntau yam khoom siv. Nws qhov ntev ntawm cov fiber sib txawv heev, tab sis tom qab ua tiav, nws tuaj yeem siv los tsim cov ntawv ntim khoom thiab cov ntawv so ntswg.

Daim Ntawv Pov Tseg: Kev Xaiv Uas Ruaj Khov

Cov ntawv pov tseg ua lub luag haujlwm tseem ceeb hauv kev lag luam ncig ntawm kev lag luam ntawv.

• Qhov Ntev ntawm Fiber: 0.7 hli txog 2.5 hli. Piv txwv li, cov fibers hauv cov ntawv pov tseg hauv chaw ua haujlwm luv luv, kwv yees li 1 hli, thaum cov fibers hauv qee cov ntawv pov tseg ntim khoom yuav ntev dua.
• Cov qoob loo ntawm cov nqaij: Nws txawv nyob ntawm hom, qhov zoo, thiab cov txheej txheem ua cov ntawv pov tseg, feem ntau yog li ntawm 60% txog 85%. Cov thawv corrugated qub (OCC) tuaj yeem muaj cov pulp tawm ntawm kwv yees li 75% txog 85% tom qab kho kom zoo, thaum cov ntawv pov tseg hauv chaw ua haujlwm sib xyaw feem ntau muaj cov txiaj ntsig ntawm 60% txog 70%.
• Cov yam ntxwvSiv cov ntawv pov tseg ua cov khoom siv raw yog tus phooj ywg ib puag ncig thiab muaj cov pulp siab. Nws yog siv dav hauv kev tsim cov ntawv rov ua dua tshiab thiab cov ntawv corrugated, pab txhawb kev txuag cov peev txheej thiab txo cov khib nyiab.

Cov Lus Cim Txog Kev Ua Cov Ntsiab Lus Tseem Ceeb

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txheej txheem pulping txawv rau ntau yam khoom siv raw.Ntoo, xyoob, straw, thiab cov qia nplej yuav tsum tau ua nojthaum lub sijhawm pulping. Cov txheej txheem no siv cov tshuaj lom neeg lossis qhov kub thiab siab kom tshem tawm cov khoom tsis yog fibrous xws li lignin thiab hemicellulose, kom ntseeg tau tias cov fibers tau sib cais thiab npaj rau kev ua ntawv.

Qhov sib txawv, kev ua cov ntawv pov tseg tsis tas yuav ua noj. Hloov chaw, nws cuam tshuam nrog cov txheej txheem xws li tshem tawm cov xim thiab kev tshuaj ntsuam kom tshem tawm cov khoom tsis huv thiab npaj cov fibers rau kev siv dua.

Kev nkag siab txog cov yam ntxwv ntawm cov khoom siv raw no yog qhov tseem ceeb rau cov neeg ua ntawv xaiv cov khoom siv zoo rau lawv cov khoom tshwj xeeb, sib npaug zoo, tus nqi, thiab kev ruaj khov. Txawm hais tias nws yog lub zog ntawm cov ntoo mos lossis qhov zoo ntawm cov ntawv pov tseg, txhua yam khoom siv raw pab txhawb rau lub ntiaj teb sib txawv ntawm cov khoom ntawv.
