Ink yuav ua tau ib tug complex nruab nrab, tsim ntawm cov kuab tshuaj, pigments, dyes, resins, lubricants, solubilizers, surfactants, particulate matter, fluorescents, thiab lwm yam ntaub ntawv.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog tus cwj mem dub ua los ntawm cov khoom?
Inks uas ntiav pigments suav nrog dawb tus cwj mem (uas muaj titanium oxide) thiab hlau kub tus cwj mem (uas, xav tsis thoob, siv tooj liab-zinc alloy.) Carbon dub , ib qho xim tau los ntawm cov thee thiab roj, yog ib feem tseem ceeb ntawm dub cwj mem ballpoint tus cwj mem.
Ib tug kuj yuav nug, dab tsi yog tus cwj mem xiav ua los ntawm? Ink tuaj yeem ua kua lossis muab tshuaj txhuam. Nws yog ib tug complex ua ke ntawm dyes, solvents, pigments thiab lubricants. Blue Ink :-Nws yog feem ntau ua los ntawm Triarylmethane dye. Dub Ink :- Cov khoom sib xyaw ntawm ntau hom thiab qee cov tshuaj tiv thaiv foaming.
Kuj tseem paub yog, cov tshuaj dab tsi hauv tus cwj mem?
Ink Cheebtsam Qhov nruab nrab ballpoint cwj mem tus number case yog tsim los ntawm dye lossis pigment hais - carbon dub rau dub cwjmem, eosin rau liab, los yog ib tug xav tias cocktail ntawm Prussian xiav, siv lead ua violet thiab phthalocyanine xiav rau classic xiav cwj mem - tshem tawm nyob rau hauv ib tug hnyav ntawm cov roj. los yog dej.
Puas yog number case sib tov?
Daim ntawv chromatography tuaj yeem siv rau tus cwj mem los txiav txim seb nws puas yog cov khoom ntshiab lossis a sib tov ntawm cov tshuaj ntshiab (nyob rau hauv uas ob los yog ntau tshaj cov tshuaj ntshiab yog ua ke). Txij li thaum kuaj nrog daim ntawv chromatography, tus cwj mem cais rau hauv nws cov ntsiab lus ntshiab, tus cwj mem yog a sib tov.

Dab tsi yog qhov me me ntawm cov khoom uas khaws cov khoom ntawm lub caij?
Ib qho atom yog qhov tsawg tshaj plaws ntawm txhua lub caij uas tseem khaws cov yam ntxwv ntawm lub caij ntawd. Ib daim ntawm ib lub caij uas peb tuaj yeem pom lossis kov yog ua los ntawm ntau, ntau atoms thiab tag nrho cov atoms yog tib yam lawv txhua tus muaj tib tus naj npawb ntawm protons
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Yuav ua li cas koj cais ib tug sib tov ntawm pigments los ntawm ib tug number case cartridge?
Txhawm rau cais qhov sib xyaw ntawm cov xim uas yog ob lub dyes, daim ntawv chromatography yog siv. Ib feem me me ntawm qhov sib tov yog muab tso rau hauv cov khoom siv absorbent, ib daim ntawv lim, nrog cov kuab tshuaj. Ob lub dyes yuav txav mus rau nyias thiab tus number case yuav sib cais rau hauv nws cov khoom ntshiab
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Yuav siv txoj kev twg los cais cov khoom ntawm tus number case?
Chromatography yog ib txoj hauv kev los tshuaj xyuas cov khoom sib tov los ntawm kev sib cais rau hauv cov tshuaj uas lawv tau tsim. Nws tuaj yeem siv los cais cov khoom sib xyaw xws li tus cwj mem, ntshav, roj av, thiab daim di ncauj. Hauv ink chromatography, koj tab tom sib cais cov xim xim uas ua rau cov xim ntawm tus cwj mem
