Thaum kuv tseem yog menyuam yaus, kuv ib txwm hnov cov laus hais tias, tsis txhob tom tus cwj mem, txwv tsis pub koj yuav raug tshuaj lom los ntawm txhuas! Tab sis qhov tseeb, cov ntsiab lus tseem ceeb ntawm cov xaum xaum yog graphite, tsis yog txhuas, thiab peb yuav tsis raug tshuaj lom los ntawm kev noj ob zaug ntxiv.
Muaj ntau lub "npe" nyob rau hauv lub neej uas tsis sib haum nrog "tiag" lub npe, xws li xaum tsis muaj hlau lead, Hiav txwv tuag tsis yog hiav txwv... Kev txiav txim ntawm ib yam khoom los ntawm lub npe ib leeg yuav tsis ua haujlwm. Yog li cov lus nug yog, puas yog lub tshuab luam ntawv lub toner tsuas yog ua los ntawm "tus cwj mem"? Cia peb saib seb lub toner zoo li cas!
Nyob rau hauv Suav teb, lub hauv paus chiv keeb ntawm tus number case yog heev thaum ntxov, thiab muaj number case sau rau ntawm oracle cov pob txha ntawm lub Shang Dynasty, thiab tus number case tau raug kuaj los ntawm cov tub txawg raws li dub carbon. Yog li Suav number case kuj hu ua carbon number, thiab toner kuj hu ua toner. Puas yog lub tshuab luam ntawv lub toner ua los ntawm "ink"? Qhov tseeb, nws txhais tau hais tias nws tsis yog ua los ntawm "carbon".
Ua tib zoo saib ntawm nws daim ntawv teev npe yuav pom tias nws muaj cov resins, carbon dub, cov neeg ua haujlwm them nqi, cov khoom siv sab nraud, thiab lwm yam, cov pa roj carbon dub ua lub cev xim, ua cov xim zas, thiab muaj cov haujlwm ntawm kev kho cov xim tob. . Hais lus nruj me ntsis, resin yog cov duab tseem ceeb ntawm toner thiab yog lub ntsiab ntawm toner.
Hauv lub neej tiag tiag, txoj kev tsim cov toner tau muab faib ua ob hom: txoj kev sib tsoo lub cev thiab cov txheej txheem tshuaj polymerization.
Ntawm lawv, kev lag luam toner siv ntau txoj kev crushing, uas tuaj yeem tsim cov toners haum rau kev luam ntawv electrostatic qhuav: suav nrog ob lub toner thiab ib qho toner (xws li sib nqus thiab tsis sib nqus). Txoj kev no yuav tsum muaj kev sib xyaw ntawm cov khoom siv sib nqus, cov khoom sib nqus, cov xim, cov tshuaj tiv thaiv tus nqi, waxes, thiab lwm yam, cua sov kom yaj cov resin, thiab tib lub sij hawm sib npaug dispersing cov khoom uas tsis yog melting rau hauv cov resin. Tom qab txias thiab solidifying, nws yog crushed thiab cais.
Nrog txoj kev loj hlob ntawm cov tshuab luam ntawv, cov kev xav tau rau toner tau nce siab dua, thiab kev tsim cov toner ntau dua. Cov txheej txheem tshuaj polymerization yog cov thev naus laus zis thev naus laus zis, thaum ntxov li xyoo 1972, thawj rooj plaub ntawm polymerization toner tshwj xeeb li tau tshwm sim rau tam sim no, thev naus laus zis tau dhau los ua neeg paub tab.
Nws tuaj yeem tsim cov toner nrog qhov ntsuas kub qis dua, uas tuaj yeem ua tau raws li cov kev xav tau ntawm cov thev naus laus zis niaj hnub rau kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig. Los ntawm kev kho qhov ntau npaum ntawm dispersant, stirring ceev, polymerization lub sij hawm thiab concentration ntawm kev daws, lub particle loj ntawm toner hais yog tswj kom ua tiav cov nyhuv ntawm uniform muaj pes tsawg leeg, zoo xim thiab siab transparency. Lub toner tsim los ntawm txoj kev polymerization muaj qhov zoo particle zoo, ib tug finer particle loj, ib tug nqaim particle loj tis thiab zoo fluidity. Nws tuaj yeem ua tau raws li cov kev xav tau ntawm cov tshuab luam ntawv niaj hnub xws li kev kub ceev, kev daws teeb meem siab thiab xim.
