100 daim ntawv thov ntawm activated carbon - luam tawm number case tshem tawm

Plaub qhov zoo tshaj plaws inventions nyob rau hauv kuv lub teb chaws thaum ub yog papermaking, lub compass, rab phom, thiab luam ntawv. Raws li ib qho ntawm plaub qhov zoo tshaj plaws inventions ntawm peb lub teb chaws, luam ntawv tau ua tsis tau zoo rau tib neeg kev vam meej. Nrog rau kev nce qib ntawm lub sijhawm, cov txheej txheem luam ntawv kuj tseem txhim kho tas li, thiab cov tshuab luam ntawv tau siv los hloov phau ntawv luam tawm hauv lub sijhawm niaj hnub no.

Printing number case

Cov tshuab luam ntawv niaj hnub no feem ntau yog tsim los ntawm cov phaj thauj khoom, daim ntawv thov number case, embossing, ntawv pub mis (xws li folding), thiab cov txheej txheem ntawm inking yuav tsum tau number case, uas yog ib qho tseem ceeb raw cov ntaub ntawv rau luam ntawv ntau lawm.

Ink yog ib qho sib tov sib xyaw ua ke ntawm lub cev muaj xim (xws li pigments, dyes, thiab lwm yam), sib txuas cov ntaub ntawv, sau (sau) cov ntaub ntawv, cov ntaub ntawv ntxiv, thiab lwm yam. Nws yog lub cev zoo li cov nplaum nplaum uas muaj xim thiab qee yam fluidity. Nws qhov kev ua tau zoo yog ncaj qha Nws cuam tshuam rau kev luam ntawv zoo thiab kev ua haujlwm ntawm cov khoom. Tam sim no, nyob rau hauv cov txheej txheem ntawm kev luam ntawv nrog lub tshuab luam ntawv, feem ntau muaj teeb meem luam ntawv zoo xws li cov hmoov xau thiab buckling ntawm cov roj hmab ntawm cov ntawv luam tawm. Feem ntau, nws feem ntau yog vim tus cwj mem impurities.

Cov pa roj carbon activated

Cov pa roj carbon activated yog ib qho tshwj xeeb kho cov pa roj carbon. Organic raw cov ntaub ntawv yog rhuab nyob rau hauv lub tsis muaj huab cua kom txo tau cov uas tsis yog-carbon Cheebtsam, thiab ces react nrog roj, thiab nto yog eroded los tsim ib tug microporous qauv. Txij li thaum cov txheej txheem ua kom pom tseeb yog cov txheej txheem microscopic, uas yog, qhov yaig ntawm ntau cov molecular carbides yog taw tes yaig, yog li qhov chaw ntawm cov pa roj carbon activated muaj countless nplua pores.

Ntxuav

Tsis tas li vim yog cov yam ntxwv ntawm cov qauv ntxeem tau ntawm cov pa roj carbon activated, cov pa roj carbon activated muaj thaj tsam loj, uas ua rau nws yooj yim heev kom ua tiav lub hom phiaj ntawm absorbing thiab sau impurities. Ib yam li lub zog sib nqus, tag nrho cov molecules muaj kev sib cuam tshuam. Vim li no, lub pore phab ntsa ntawm activated carbon Ib tug loj tus naj npawb ntawm molecules nyob rau saum npoo tuaj yeem tsim kom muaj zog gravitational quab yuam, yog li ua tiav lub hom phiaj ntawm kev nyiam cov impurities hauv cov luam ntawv number case rau hauv qhov pores.
