Nws yog qhov paub zoo tias cov ntawv luam tshuaj ntsuab yog ua los ntawm cov khoom siv tshuaj, uas yuav ua rau muaj kev ua qias tuaj rau zaub mov tom qab sib cuag nrog zaub mov. Yog tias koj siv cov kua roj ntsuab ntsuab li lub hnab ntim khoom luam, muaj qee qhov muaj kuab paug. Txhua tus tivthaiv ntawm tus cwjpwm uas tsim nyog yuav tsum tau ua raws li cov kev txwv ntawm cov zaub mov uas tsis yog lom, txawm yog lub cev lossis tshuaj, cov khoom uas tau ua tomqab sib txuas nrog zaubmov yuav tsum tsis ua rau tus tibneeg lub cev, thiaj li ua tau raws li cov qauv hauv tsev thiab thoob ntiaj teb, xws li United Xeev. FD & C (Tsoom Fwv Teb Chaws Zaub Mov, Tshuaj Yeeb, Tshuaj Tshuaj Tiv Thaiv) Cov cai, EU EEC (Cov khoom noj khoom haus nyob sab Europe thiab tshuaj) cov cai thiab lwm cov cai.
Ntsuab cov phev mas feem ntau yog ua raws li cov qauv txheej txheem thiab muaj kev nyab xeeb hauv cheeb tsam uas tau lees paub los ntawm cov koom haum tshwj xeeb hauv teb chaws thiab tsis tsim kev puas tsuaj rau tib neeg kev noj qab haus huv thiab kev thaj yeeb. Tus lej muaj plaub yam: pigment, binder, solvent thiab cosolvent. Thaum tsim cov tshuaj ua tau zoo, thawj qhov kev xaiv yog cov pigments li cov xim tha xim, xws li cov pa pigments, uas muaj ntau yam xim thiab muaj peev xwm txawm tias tus nqi noj haus, lossis kev kho mob thiab kev nyab xeeb tuaj yeem ntseeg tau. Qhov tsis zoo yog tias feem ntau yam pigments tsis ruaj khov txaus, thiab cov qauv molecular hloov tau thaum uas cuam tshuam los ntawm cov kua qaub, alkali, sov, thiab lwm yam., Uas yuav ua rau muaj kev sib thab, ua kom poob lossis xim.
Txawm li cas los xij, tus qauv ntawm kev noj qab haus huv ntsuab tsis ruaj tsis khov, thiab tib neeg txoj kev xav mus rau qhov khoom noj khoom haus kev nyab xeeb tau ua rau lub ntiaj teb txoj kev loj hlob ntawm natural pigments muaj zog. Hauv qee lub teb chaws, cov khoom pigments muaj ntau tshaj li cov khoom xyaw hluavtaws pig. Tam sim no, feem ntau ntawm cov khoom noj tau yooj yim dua yog cov nroj tsuag pigments xws li cov liab liab liab, anthocyanin, carmine, thiab curcumin.
Lub khawm ntawm tus cwj pwm uas rov qab los yog tsim los ntawm cov roj, ib qho hnyav thiab ib tus neeg saib xyuas nws tus kheej. Ntawm lawv, cov roj zaub xws li txiv laum huab xeeb thiab roj salad yog siv los ua cov roj, thiab cov tshuaj hnyav yuav ua kua qab zib. Cov kaus poom hauv cov khoom noj tau muab luam tawm ntawm cov khoom noj ntim thiab cov cheeb tsam uas lawv khaws cia nws txawv nrog rau qhov khoom noj ntawd nws tus kheej cia. Piv txwv, qee cov khoom noj yuav tsum tau khov, txawm lwm tus tsis tas yuav; qee qhov yuav tsum tau tiv thaiv kev kub siab, los yog yuav tsum tau siv rau hauv microwave ncu, tag nrho cov uas cuam tshuam rau kev xaiv ntawm cov neeg sawv cev ua ke.
Nyob rau hauv lub cev cuav quav system, additives yog ib qho tseem ceeb heev. Yog tias tsis muaj cov teebmeem ntawm cov khoom siv ntxiv, tus lej tsis muaj peev xwm tsim tau lub cev khov kho. Tib yam muaj tseeb rau cov roj tov tau, xws li cov tuab tuab, cov hmoov av, cov khoom ntim, cov tshuaj tua kab, cov tshuaj ruaj ruaj, thiab lwm yam. Emulsifiers thiab hydrocolloid stabilizers ua raws li stabilizers thiab thickeners nyob rau hauv tus number case. Lwm cov ntaub ntawv yog lecithin, kua qaub, thiab cov zoo li.
Piv txwv, ib qho kua cawv uas siv dej, pigment, xanthan gum, sucrose los yog soybean roj li raw cov ntaub ntawv muaj kev ruaj khov thiab zoo heev viscosity, thiab tsis hloov ntau yam hauv lub sij hawm ntev. Cov lej ntawm qhov siv tsis muaj delamination thiab tsis muaj deterioration, thiab yuav khaws cia rau tsawg kawg ib lub hlis tsis muaj preservatives, thiab muaj zoo stability. Cov ntsiab lus ntawm xanthan ntawm cov pos hniav ua ib lub thickening emulsifier nyob rau hauv cov number case ncaj qha rau cov fluidity ntawm tus cwj pwm, thiab tus nqi yuav tsum tau precisely tswj.
Ib qho tseem ceeb tshaj plaws nyob rau hauv kev txiav txim siab seb puas muaj tus cwj pwm uas muaj yees rov tuaj yeem siv rau kev luam tawm yog thixotropy. Tus thixotropy thiaj li yog ib qho phenomenon uas tus number case ua thinner los yog thicker thiab qhov fluidity hloov hauv lub hwj thiab cuam tshuam ntawm sab nraud force thiab sab nraud environmental factors. Nyob rau hauv cov txheej txheem luam ntawv, tus number case yuav tsis tshua tau ua thixotropic, uas ua rau cov khoom tsis muaj zog tsis txaus ntseeg. Ua tib zoo nkag siab txog thixotropy ntawm tus cwj pwm, siv cov kev tiv thaiv los ntawm txoj kev thiab cov cuab yeej los mus kov yeej, los txo cov teeb meem ntawm thixotropic hauv ink printing, thiaj li yuav zoo dua qub rau kev luam cov khoom zoo.
Cov xim pleev xim ntawm liab poov liab, vaj tsev xiav, thiab gardenia daj pigment yog tus ruaj khov rau pH, thiab xim tsis hloov hauv acidic thiab alkaline tej yam kev mob. Cov kev ntsuam xyuas tau pom tias thaum cov kua roj kua roj tsawg yog li ntawm 33% ntawm tag nrho cov lej ntawm cov cwj mem thiab cov ntsiab lus sucrose yog kwv yees li 28%, cov cwj pwm ntawm cov kab rov tuaj yeem tuaj yeem muaj cov nyhuv zoo los ntawm kev tshuaj ntsuam ntawm cov khoom noj.
Raws li cov ntaub ntawv luam, thaum tus number case yog siv rau cov zaub mov ntim, txoj cai tsis muaj kev tsiv teb tsaws yuav tsum tau pom. Kev ntim zaub mov yuav tsum tsis txhob siv cov tshuaj nplaum los txhawm rau paub tseeb tias qhov hnyav ntawm tus cwj pwm tom qab luam ntawv tag tsis muaj zog, tus cwj mem yog kho kom huv si thiab ua tau raws li cov qauv hauv daim ntawv thov kev lag luam. Nyob rau hauv cov zaub mov tam sim no yas ntim ntawv luam, kev siv thaj tsam zoo rau cov khoom noj tsis zoo yuav tsis cuam tshuam rau ib puag ncig, txo cov kev raug mob hauv kev lag luam luam, thiab yuav tsis ua kom cov ntsiab lus ntawm cov zaub mov.
Nrog rau kev sib ntau ntawm kev luam ntawv thiab kev tsim cov inkjet luam tawm, tau ntxim rau inkjet inks yuav dhau mus ua qauv tshiab. Kev tsim kho ntawm kev siv tshuab thiab kev hloov ntawm tib neeg txoj kev xav tau ua rau muaj ntau dua thiab nrov dua thiab muaj peev xwm ua ntawv thov mus rau ntau thaj chaw. Thaum cov neeg raug cov kabmob ntau tshaj tawm cov khoom luam tawm, nws yog nyob ib ncig ntawm lub kaum tsev kawm ntawv kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig los ntawm lub kiv puag ncig hauv cov ntaub ntawv luam tawm.
