Offset Printing Ink Yuav Tsum Tau Them Rau Lub Sijhawm Rau Qhov Ntsuas
Jan 18, 2023
1. Concentration: Ink concentration yog cov ntsiab lus xim ntawm cov xim xim, feem ntau suav txog li 20 feem pua ntawm tag nrho cov number case. Feem ntau los ntawm kev tshawb pom cov xim muaj zog los txiav txim qhov loj ntawm tus number case concentration. Hauv kev luam ntawv nrog tib tus lej ntawm tus number case, number case concentration, xim ntawm cov ntawv luam tawm yog tuab, thiab vice versa, xim ntawm cov luam ntawv yog lub teeb. Tshwj xeeb tshaj yog thaum luam ntawv loj ntawm thaj chaw, qhov concentration ntawm tus number case rau ntawm qhov cuam tshuam ntawm kev luam ntawv zoo yog qhov tseem ceeb.
2. Fineness: lub fineness ntawm tus number case qhia tias tus number case pigment, muab tub lim particle loj thiab uniformity ntawm tis nyob rau hauv cov khoom sib txuas. Lub fineness ntawm tus number case thiab qhov xwm ntawm cov xim thiab particle loj muaj ib tug ncaj qha kev sib raug zoo. Qhov zoo dua qhov zoo, qhov ruaj khov ntawm tus cwj mem, cov khoom luam tawm network yog tag nrho thiab muaj zog. Conversely, nyob rau hauv lub luam ntawv phaj yog nws tsis tshua muaj luam kuj, number case pawg, network emptiness, expansion thiab network tsis glossy thiab lwm yam ills.
3. Viscosity: viscosity ntawm tus number case nrog tus number case viscosity meter test. Qhov luaj li cas ntawm tus number case viscosity tus nqi yog qhov loj ntawm lub zog uas sib cais cov kua nplaum zaj duab xis ntawm ob lub rollers ntawm viscometer. Ink viscosity loj dhau los yog tsawg dhau yuav cuam tshuam rau kev luam ntawv zoo. Tsis tas li ntawd, raws li kev txiav txim luam ntawv los xaiv qhov txheeb ze viscosity loj ntawm txhua tus number case xim. Nyob rau hauv cov xwm txheej ib txwm, nws tsis yog yuav tsum tau kho cov viscosity ntawm tus number case, yog tias koj xav tau kho cov viscosity, sib xws ntawm qhov xwm txheej los xaiv cov additives.
4. gloss: ink gloss yog tus number case printing qauv nyob rau hauv ib tug tshwj xeeb lub teeb qhov chaw, ib tug tej lub kaum sab xis ntawm irradiation, tus nqi ntawm lub teeb reflected thiab tus nqi ntawm lub teeb reflected los ntawm tus qauv phaj, qhia raws li ib feem pua. Feem ntau hais lus qhov siab dua qhov luster zoo dua qhov kev luam ntawv zoo dua. Txawm hais tias cov luster ntawm cov ntawv luam tawm thiab luam ntawv nrog cov tshuaj ntub dej siv, qhov nqus ntawm daim ntawv kuj muaj qee yam kev sib raug zoo, tab sis feem ntau yog los ntawm tus cwj mem txiav txim. Qhov xwm ntawm tus cwj mem thiab feem ntau yog nyob ntawm cov khoom sib txuas thiab cov pigments. Kev sib txuas cov ntaub ntawv thiab cov pigments hauv tus number case kom muaj kev luam tawm zoo, ntxiv rau cov resin nws tus kheej siab gloss. Xws li tus cwj mem luam tawm ntawm daim ntawv duab gloss yog siab.
5. Dryness: offset number case drying txheej txheem ntawm daim ntawv yog tus number case los ntawm lub liquidity ntawm lub non-polar colloid mus rau hauv ib tug taag lub xeev ntawm cov txheej txheem. Qhov kev ntsuas dav dav ntawm tus cwj mem offset tau muab faib ua ob qhov ntsuas ntawm fixation ceev thiab oxidation zaj duab xis kom qhuav. Tam sim no, offset luam ntawv number case yog resin-raws li, ceev fixation ceev. Raws li txoj cai, qhov pib qhuav sai dua, tab sis qhov pib qhuav sai heev yuav cuam tshuam rau qhov ci ntawm cov ntawv luam tawm. Feem ntau txog 80 feem pua ntawm cov kua nplaum crystalline zaj duab xis ziab lub sijhawm ntawm 16-30 teev.
6. Xim stability
Rau cov tshuab luam ntawv, kev ruaj ntseg ntawm tus number case kuj muaj feem xyuam rau qhov zoo ntawm cov luam ntawv. Muaj cov tshuab luam ntawv siv tib lub hom thiab tib cov qauv number case txheej txheem, txawm hais tias tus number case formula thiab siv tib ib puag ncig, tab sis vim muaj kev hloov pauv ntawm cov ntaub ntawv raw thiab cov khoom siv ntawm cov kua number case, uas ua rau tib lub hom thiab qauv ntawm tus number case kev ua tau zoo. sib txawv. Tshwj xeeb tshaj yog tam sim no cov ntaub ntawv ntawm kev nce siab ntawm kev tiv thaiv ib puag ncig, cov khoom siv tshuaj lom neeg feem ntau ntsib kev tsis txaus thiab tus nqi nce, cov chaw tsim khoom siv number case kom paub tseeb tias kev tsim khoom thiab cov nqi txiav txim siab raug khi los hloov qee cov ntaub ntawv raw, xws li nrog tib tus cwj mem liab, raws li. rau tib qhov kev faib ua feem ntawm tus cwj mem hloov, tab sis muaj qhov sib txawv xim tseem ceeb.
Nyob rau hauv luv luv, cov tshuab luam ntawv xaiv tus cwj mem haum, thiab feem ntau tsom rau saum toj no rau lub cim tseem ceeb ntawm tus number case, ces qhov teeb meem ntawm tus number case yuav tsis thab koj ntau lawm, yog li txhim kho efficiency thiab cov khoom zoo.
