Leej twg tsim papermaking? Dab tsi yog qee qhov nthuav tawm me me?

Papermaking yog ib qho ntawm plaub qhov kev tsim tawm loj ntawm Tuam Tshoj. Nyob rau sab hnub poob Han dynasty, cov neeg twb to taub cov txheej txheem theem pib ntawm papermaking. Nyob rau sab hnub tuaj han dynasty, eunuch CAI LUN sau lub ntsiab lus ntawm nws cov kev paub thiab txhim kho cov txheej txheem papermakaking, uas tau zoo dua txhim kho cov ntawv zoo. Txij thaum ntawd los, kev siv daim ntawv tau dhau los ua ntau dua. Daim ntawv tau maj mam hloov xyoob thiab lo lo ntxhuav, ua cov khoom siv sau cia siv dav, thiab kuj tau yooj yim rau kev sib kis ntawm classics.

CAI LUN qhov kev txhim kho tau tsim cov txheej txheem sib txawv ntawm cov txheej txheem, uas tuaj yeem yog cov lus hais tawm hauv cov kauj ruam hauv qab no:
Kev sib cais: Siv tus txheej txheem ntawm kev rov ua lossis rhaub kom degumming cov ntaub ntawv raw hauv alkali daws thiab tawg rau lawv mus rau hauv fibers.
Pulping: Siv txoj kev txiav thiab phaw kom txiav cov fibers thiab ua rau lawv broom los ua ntawv pulp.
Papermaking: Ua daim ntawv ntawv SCP dej kom ua rau pulp, thiab tom qab ntawd cov ntaub qhwv yog cuam tshuam rau daim ntawv tawv nqaij tawv.
Kom qhuav: qhuav daim ntawv ntub nyob rau hauv lub hnub lossis huab cua, thiab tev nws los ua ntawv.

Keeb kwm ntawm papermaking: papermaking nyob rau hauv ntau lub teb chaws thoob ntiaj teb tau dhau los ntawm Suav teb. Qhov tsim muaj ntawm papermaking yog ib qho ntawm Tuam Tshoj txoj kev txhawb nqa zoo rau ntiaj teb kev vam meej. At the 20th Congress of the International Papermaking History Association held in Malmedy, Belgium from August 18 to 22, 1990, experts unanimously agreed that Cai Lun was the great inventor of papermaking and China was the country that invented papermaking.

Qhov tseem ceeb ntawm Papermaking: qhov tsim muaj ntawm papermaking kuj tseem ceeb toom peb ntawm qhov tseem ceeb ntawm kev tshawb fawb thiab thev naus laus zis. Nyob rau hauv cov txheej txheem ntawm kev tsim cov ntawv thov, CAI LUN siv ntau txoj kev tshiab thiab thev naus laus zis los ua lub teeb ci, kev lag luam thiab khaws cia yooj yim. Cov txheej txheem no qhia txog lub luag haujlwm tseem ceeb ntawm kev tshawb fawb thiab kev tsim kho thev naus laus zis hauv kev txhawb kev sib raug zoo. Hauv lub zej zog niaj hnub, kev tshawb fawb thiab thev naus laus zis tau dhau los ua lub zog tseem ceeb los txhawb kev sib raug zoo. Raws li cov tub ntxhais kawm qib siab, peb yuav tsum txuas ntxiv tshawb nrhiav thiab tsim kho kom tau txais kev hloov pauv thiab cov kev sib tw.
