Cov ntaub ntawv ntawm cov ntawv ntim cov khoom lag luam tau muab faib ua ntau hom, 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, ntawm ntau cov ntaub ntawv siv hauv ntim ntawv tais cov khoom. Feem ntau ntawm lawv yog cov dawb pulp 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 ci li A4 daim ntawv peb feem ntau siv nyob rau hauv chaw ua hauj lwm.
Thib ob, saib qhov toughness ntawm cov khoom, cov txheej txheem ntub dej dav dav tsis tshua siv cov tawv nqaij dawb. Yog li ntawd, los ntawm qhov kev xav ntawm cov ntawv xovxwm qhuav, cov nplaum nplaum nplaum yog mos vim nws cov fiber ntau thiab cov khoom nias qhuav nws tus kheej tsis yog qhov tshwj xeeb, uas ua rau lub hardness ntawm qhuav - cov nplaum nplaum nplaum ntim ntawv yuav tsis zoo li cov ntaub ntawv dawb.
Feem ntau, cov khoom uas tau xaiv rau cov txheej txheem qhuav nias yog txiav txim siab los ntawm kev tiv thaiv cov khoom. Yog li ntawd, nws raug nquahu kom koj xaiv cov ntaub ntawv dawb paug thaum ua cov ntawv xovxwm qhuav. King Superman Ntim yog lub chaw tsim khoom loj- nplai ntawv tais uas tuaj yeem ua raws li kev tsim khoom ntawm ntau hom ntim ntawv tais xws li cov tais ntawv, ntawv yas, ib puag ncig tiv thaiv daim ntawv tais, pulp molding, ntub daim ntawv tais, qhuav nias ntawv tais, thiab lwm yam. Zoo siab txais tos rau kev sab laj.
