Cov ntaub ntawv ntawm cov ntaub ntawv tais yog muab faib ua ntau yam, xws li xyoob pulp, ntoo pulp, corrugated pulp, loj dawb pulp (tseem hu ua dawb pulp los yog A4 pulp), qab zib pulp, thiab lwm yam., uas yog siv nyob rau hauv ntau yam ntaub ntawv ntawm cov ntaub ntawv tais cov khoom. Muaj cov pulp dawb thiab qab zib pulp. Yuav ua li cas paub qhov txawv ntawm ob?
Qhov tseeb, nws yooj yim heev. Ua ntej ntawm tag nrho cov, los ntawm kev xav ntawm cov xim, txawm hais tias lawv yog tag nrho cov dawb, daim ntawv tais ntawm qab zib pulp yuav saib ib tug me ntsis yellower, thiab cov pulp dawb yuav dawb li A4 daim ntawv peb feem ntau siv nyob rau hauv chaw ua hauj lwm. Qhov thib ob, saib qhov toughness ntawm cov khoom. Feem ntau, cov pulp dawb tsis tshua siv rau hauv cov txheej txheem ntub dej. Yog li ntawd, nyob rau hauv cov nqe lus ntawm qhuav pressing khoom, qab zib pulp yog mos vim hais tias ntawm nws cov mos fibers thiab qhuav pressed khoom lawv tus kheej tsis compacted, uas ua rau qhuav pressed qab zib hardness ntawm pulp ntawv tais cov khoom yog tsis zoo li cov ntaub ntawv dawb. Feem ntau, cov khoom ntawm cov txheej txheem xovxwm qhuav yog txiav txim siab los ntawm kev tiv thaiv cov khoom, yog li nws raug pom zoo tias koj tuaj yeem xaiv cov ntawv xovxwm dawb thaum ua cov ntawv xovxwm qhuav.
