kraft ntawv yog dab tsi?
Kraft daim ntawv yog daim ntawv tsim los siv cov txheej txheem tshwj xeeb ntawm cov txheej txheem pulping, feem ntau, hauv cov ntawv ua, cov ntoo yog thawj "sib tsoo", thiab tom qab ntawd cov cellulose pulp tau kho nrog qee yam tshuaj (sulfate) los txhim kho lub zog ntawm daim ntawv. Yog li ntawd, nws muab nws lub npe kraft ntawv.
Qhov no yog vim li cas cov ntaub ntawv no tau siv los ua cov khoom ntim vim nws cov khoom siv ruaj khov thiab muaj txiaj ntsig zoo hauv kraft ntawv ntim.
Kraft daim ntawv yog cov ntawv ntim dej tsis zoo, cov xim xim av-daj, dav siv, feem ntau siv los ua cov hnab ntawv, hnab ntawv, phau ntawv qoj ib ce, lub tes tsho, yob thiab ntawv xuab zeb. Cov kev cai tseem ceeb yog hloov tau thiab muaj zog, siab rupture kuj, thiab muaj peev xwm tiv taus ntau dua thiab siab tsis tawg. Kraft daim ntawv muaj lub zog tensile siab, ib lub teeb, ob lub teeb, kab txaij, tsis muaj kab thiab lwm yam. Nws yog tsuas yog siv rau wrapping ntawv, hnab ntawv, hnab ntawv, thiab lwm yam., thiab lub nruas ntawm lub tshuab luam ntawv.
Kraft daim ntawv feem ntau khaws nws cov xim daj xim av, haum rau lub hnab thiab qhwv ntawv. Raws li qhov xwm txheej thiab kev siv sib txawv, kraft ntawv muaj ntau yam kev siv sib txawv. Kraft daim ntawv yog ib lo lus dav dav rau daim ntawv, thiab tsis muaj qee qhov tshwj xeeb, thiab nws feem ntau raug cais raws li nws qhov xwm txheej thiab kev siv.
Raws li cov xim sib txawv tuaj yeem muab faib ua: thawj kraft ntawv, xim av kraft ntawv, dawb kraft ntawv, kraft ntawv dawb, ib lub teeb kraft ntawv, ob-xim kraft ntawv thiab hais txog.
Raws li kev siv sib txawv tuaj yeem muab faib ua: ntim cov ntawv kraft, ntawv tsis muaj dej tsis muaj dej, ntawv pov thawj kraft, xeb-pov thawj kraft ntawv, phaj kraft ntawv, txheej txheem kraft ntawv, insulating kraft ntawv board, kraft ntawv nplaum thiab lwm yam.
Raws li cov ntaub ntawv sib txawv tuaj yeem muab faib ua: cov ntawv kraft rov siv dua, kraft core ntawv, kraft puag ntawv, coarse kraft ntawv, kraft wax ntawv, ntoo pulp kraft ntawv, composite kraft ntawv thiab lwm yam.
Kraft daim ntawv muab faib ua peb hom: ib sab, ob sab thiab kab txaij; Raws li nws thickness yog muab faib ua kraft ntawv, kraft ntawv, kraft ntawv board. Kraft daim ntawv yog dav siv los ua lub thawv ntim khoom vim nws cov yam ntxwv tseem ceeb yog kev hloov pauv hloov tau yooj yim, thiab muaj kev tawg loj, folding tsis kam thiab dej tsis zoo, yog li nws tau dav siv hauv kev tsim cov thawv ntim khoom tawv tawv, cov thawv ntim tshuaj pleev ib ce, kev lag luam. cov khoom lag luam, textiles, cov khoom siv niaj hnub, cov yeeb yaj kiab, cov khoom siv raw khoom ntim.
