Kraft daim ntawv tau dhau los ua qhov kev xaiv vim nws lub zog siab, ntau yam, thiab tsis tshua muaj kev cuam tshuam ib puag ncig. Nws yog 100% recyclable thiab ib puag ncig tus phooj ywg, nrog rau keeb kwm ntev ntawm kev tsim khoom uas suav nrog ntoo fibers, dej, tshuaj, thiab cua sov. Kraft daim ntawv muaj zog dua thiab ntxeem tau, ua rau nws haum rau cov txheej txheem tshwj xeeb. Nws yog siv dav hauv kev ntim khoom, xws li cov thawv ntawv thiab cov hnab ntawv, thiab muaj ntau hom kev faib raws li lawv qhov xwm txheej thiab lub hom phiaj.
1.Dab tsiyog kraft ntawv?
Kraft daim ntawv yog hais txog cov ntawv lossis cov ntawv ua los ntawm cov ntaub so ntswg siv cov txheej txheem kraft papermaking. Vim yog cov txheej txheem kraft pulping, kraft ntawv muaj cov kav ntev, dej tsis kam, thiab tsim kua muag, thiab nws cov xim feem ntau yog xim daj-xim av.
Kraft pulp muaj xim sib sib zog nqus dua li lwm cov ntoo pulp, tab sis nws tuaj yeem bleached los tsim cov xim dawb heev. Tag nrho cov bleached kraft pulp yog siv nyob rau hauv zus tau tej cov ntaub ntawv zoo qhov twg lub zog, whiteness, thiab kuj mus yellowing yog ib qho tseem ceeb heev.
2. Keeb kwm thiab txheej txheem ntawm Kraft daim ntawv
Kraft daim ntawv, ib qho khoom ntim khoom siv feem ntau, muaj npe rau nws cov txheej txheem pulping. Cov txheej txheem kraft papermaking yog tsim los ntawm Carl F. Dahl nyob rau hauv Danzig, Prussia (tam sim no Gdańsk, Poland) nyob rau hauv 1879. Lub npe kraft yog muab los ntawm German lo lus "Kraft," uas txhais tau hais tias lub zog los yog vitality.
Cov ntsiab lus tseem ceeb rau kev tsim cov kraft pulp yog ntoo fibers, dej, tshuaj, thiab cua sov. Kraft pulp yog tsim los ntawm kev sib xyaw cov ntoo fibers nrog kev daws ntawm caustic soda thiab sodium sulfide thiab ua noj rau hauv lub digester.
Tom qab ua tiav ntau yam kev tsim khoom xws li impregnation, ua noj, pulp bleaching, ntaus, sizing, whitening, purification, screening, forming, dehydration and pressing, drying, calendering, and winding, with the nruj txheej txheem tswj, kraft pulp yog thaum kawg hloov mus rau hauv. kraft ntawv.
3. Kraft Daim Ntawv vs. Cov Ntawv Tsis Siv Neeg
Qee tus yuav sib cav tias nws tsuas yog ntawv xwb, yog li dab tsi tshwj xeeb ntawm kraft ntawv?
Hauv cov ntsiab lus yooj yim, kraft ntawv muaj zog dua.
Vim tias cov txheej txheem kraft pulping tau hais ua ntej, ntau lignin raug tshem tawm ntawm kraft pulp ntoo fibers, tawm hauv qab ntau fibers. Qhov no muab cov ntawv nws tsim kua muag thiab durability.
Unbleached kraft ntawv feem ntau yog ntxeem tau ntau dua li cov ntawv ib txwm, uas yuav ua rau cov ntawv luam tawm me ntsis. Txawm li cas los xij, qhov porosity no ua rau nws tsim nyog rau qee yam txheej txheem tshwj xeeb, xws li embossing lossis kub stamping.
4.Kev siv cov ntawv Kraft hauv ntim
Niaj hnub no, kraft ntawv feem ntau yog siv rau cov thawv corrugated thiab tsim cov hnab ntawv uas tsis muaj kev phom sij, xws li cov khoom siv cement, zaub mov, tshuaj, khoom siv, thiab hmoov nplej.
Vim nws cov durability thiab practicality, corrugated thawv ua los ntawm kraft ntawv yog heev nrov nyob rau hauv lub express xa thiab logistics kev lag luam. Cov thawv no zoo tiv thaiv cov khoom thiab tuaj yeem tiv taus kev thauj mus los hnyav. Tsis tas li ntawd, tus nqi-zoo ntawm cov ntawv kraft ua rau nws yog qhov kev xaiv tsim nyog rau kev txhim kho kev lag luam.
Kraft daim ntawv thawv kuj feem ntau siv los ntawm cov tuam txhab kom ua tiav cov hom phiaj kev txhim kho kom ruaj khov, qhia meej meej txog kev tiv thaiv ib puag ncig los ntawm rustic thiab nyoos zoo li xim av kraft ntawv. Kraft daim ntawv muaj ntau yam kev siv thiab tuaj yeem muab ntau yamkev ntim khoom tshiabkev daws teeb meem hauv kev lag luam ntim niaj hnub no.
5. Hom Kraft Daim Ntawv
Kraft daim ntawv feem ntau khaws nws cov xim daj-xim av, ua rau nws tsim nyog rau kev tsim cov hnab thiab qhwv ntawv. Muaj ntau hom ntawv kraft raws li nws cov khoom thiab kev siv. Kraft daim ntawv yog ib lo lus dav dav rau ntawv thiab tsis muaj cov qauv tshwj xeeb. Nws yog feem ntau cais raws li nws cov khoom thiab npaj siv.
Los ntawm cov xim, kraft ntawv tuaj yeem muab faib ua tej yam ntuj tso kraft ntawv, liab kraft ntawv, dawb kraft ntawv, matte kraft ntawv, ib sab gloss kraft ntawv, dual-xim kraft ntawv, thiab lwm yam.
Raws li nws daim ntawv thov, kraft ntawv tuaj yeem muab faib ua cov ntawv ntim kraft, ntawv kraft tsis muaj dej, ntawv kraft ntawv, kraft ntawv tsis xeb, ntawv kraft ntawv, insulating kraft paperboard, kraft stickers, thiab lwm yam.
Raws li nws cov khoom muaj pes tsawg leeg, kraft ntawv tuaj yeem muab faib ua cov ntawv kraft rov ua dua, kraft ntawv tseem ceeb, kraft puag ntawv, kraft daim ntawv, ntoo pulp kraft ntawv, composite kraft ntawv, thiab lwm yam.
Hom Hom Kraft Daim Ntawv
1. Coated Unbleached Kraft Paper (CUK)
Cov khoom no yog suav tias yog qhov yooj yim tshaj plaws version ntawm kraft ntawv. Nws tsis dhau ib qho "bleaching" lossis ntxiv tshuaj ntxiv, ib sab ntawm cov tshuaj siv hauv cov txheej txheem kraft pulping. Raws li qhov tshwm sim, nws tseem hu ua cov khoom tsis muaj tshuaj dawb los yog sulfite, muaj 80% nkauj xwb fiber ntoo pulp / cellulose kraft pulp. Nws nthuav tawm cov kua muag zoo heev thiab siab tawv yam tsis muaj tuab heev. Qhov tseeb, nws yog qhov thinnest ntawm tag nrho cov kraft ntawv ntim substrates.
2. Khoom Kraft Daim Ntawv (SBS)
Txawm hais tias tsis muaj kraft ntawv yog suav tias yog ib puag ncig zoo dua vim nws cov xim ntuj thiab tsis muaj tshuaj kho mob, nws yuav tsis yog qhov kev xaiv zoo tshaj plaws rau qee yam kev siv, xws li ntim khoom rau khoom kim heev lossis high-end khoom. Nyob rau hauv cov ntaub ntawv no, bleached kraft ntawv tej zaum yuav zoo dua vim hais tias nws muaj ib tug smoother nto thiab ib tug brighter tsos, uas yuav txhim khu kev luam ntawv zoo thiab muab ib tug hwm zoo saib thiab zoo.
3. Coated Recycled Board (CRB)
Coated recycled board yog ua los ntawm 100% recycled kraft ntawv. Vim nws tsis yog tsim los ntawm nkauj xwb fibers, nws specifications thiab kam rau ua yog tsawg tshaj li cov khoom bleached kraft ntawv. Txawm li cas los xij, cov ntawv kraft rov ua dua tshiab kuj yog cov khoom ntim qis qis, ua rau nws zoo rau cov ntawv thov uas tsis tas yuav muaj kua muag los yog lub zog, xws li cov thawv ntim khoom noj. Rau cov thawv corrugated, ntau yam tuaj yeem ua tiav los ntawm kev ntxiv cov ntawv kraft.
