Cov ntawv tshwj xeeb yog hais txog cov ntawv tsim los ntawm cov tshuab papermaking siv ntau cov fibers -xws li hluavtaws fibers, hluavtaws pulp, los yog blended ntoo pulp- feem ntau ua ke nrog lwm cov ntaub ntawv los muab cov haujlwm tshwj xeeb. Los ntawm kev hloov kho thiab kev ua tiav, daim ntawv tau txais ntau lub peev xwm thiab kev siv, xws li cov khoom siv niaj hnub, cov khoom siv hauv tsev, thiab cov khoom siv hluav taws xob mus rau cov lim dej, cov khoom siv hluav taws xob, cov khoom siv ua liaj ua teb, cov ntaub ntawv thev naus laus zis, optics, kos duab thiab kab lis kev cai, thiab kev txiav -ntev biochemical technologies. Hais lus dav dav, txhua yam ntaub ntawv tsim los rau ib lub hom phiaj tshwj xeeb yog sib sau ua ke raws li daim ntawv tshwj xeeb.
Cov ntawv tshwj xeeb yog ib lo lus sib sau ua ke rau cov ntaub ntawv nrog cov ntawv tshwj xeeb thiab cov khoom siv qis dua; nws tseem raug hu ua "tshwj xeeb- ntawv hom phiaj" lossis "daim ntawv kos duab." Pawg no nthuav dav kaum ob qhov loj, suav nrog kab lis kev cai, ntim khoom, kev tsim kho, thiab kev kho mob. Nws cov ntaub ntawv raw muaj xws li cog fibers, hluavtaws fibers, thiab inorganic fibers. Los ntawm cov txheej txheem ua ntawv tshwj xeeb thiab kev kho saum npoo- xws li txheej txheej - cov ntaub ntawv no tau txais txiaj ntsig nrog cov khoom xws li dej tsis kam, hluav taws kub, thiab muaj peev xwm tiv thaiv kab mob. Piv txwv li, cov ntawv tsis muaj carbonless siv cov tshuab microencapsulation los ua kom muaj kev ua haujlwm duplicate, thaum nano- ntawv tsis muaj dej tsis sib xyaw nrog nanomaterials los txhim kho hydrophobicity.
Cov khoom lag luam no tau tsim nyob rau xyoo 1940 nrog kev tsim cov ntawv tsis muaj carbonless hauv Tebchaws Meskas. Nyob rau hauv Suav teb, kev lag luam tau pom ib qho kev nthuav dav zuj zus txij li xyoo 2010; los ntawm 2022, cov khoom tsim tawm tau mus txog 4.12 lab tons, ua rau tsim cov cheeb tsam kev lag luam hauv cheeb tsam xws li Quzhou thiab Zhutai Town. Cov thev naus laus zis ntau lawm suav nrog cov txheej txheem xws li microencapsulation structuring, kev ruaj ntseg xov kev sib koom ua ke rau kev tiv thaiv- cuav, thiab fiber ntau. Cov khoom piv txwv suav nrog cov ntawv tiv thaiv-xeb, ntawv aramid, thiab ntawv-raws li cov ntaub ntawv nres, uas pom cov ntawv thov hauv kev ruaj ntseg nyiaj txiag, cov khoom siv dav hlau, thiab eco- cov khoom siv hauv tsev. Kev lag luam tam sim no ntsib cov teeb meem xws li nce nqi ntoo pulp thiab kev cia siab rau cov thev naus laus zis txawv teb chaws; yog li ntawd, nws tau nquag hloov mus rau ntsuab, qis- qauv tsim cov pa roj carbon.
