Hauv cov ntsiab lus ntawm kev luam ntawv, kev tswj tsis txaus ntawm tus lej viscosity tuaj yeem ua rau muaj ntau yam teeb meem ua haujlwm?

- Tshaj Viscosity: Thaum tus number case viscosity siab dhau lawm, nws qhov kev nplaum nplaum thiab nyiam tsim cov filaments ntev thaum hloov ntawm cov menyuam tuaj yeem ua rau ya tus number case, ib qho tshwm sim uas tawg filament xaus rau hauv huab cua. Cov nyhuv no yog exacerbated thaum lub sij hawm high-speed printing.
- Daim ntawv puas: Cov number case viscosity siab tuaj yeem dhau lub zog saum npoo ntawm daim ntawv, ua rau hmoov, fibrillation, los yog delamination, tshwj xeeb tshaj yog pom ntawm cov ntaub ntawv nrog cov qauv xoob thiab lub zog qis.
- Ink Transfer Inefficiencies: Siab viscosity hampers npaum tus number case hloov ntawm cov menyuam mus rau cov menyuam thiab mus rau lub phaj luam ntawv lossis substrate vim muaj kev sib raug zoo ntawm tus lej hloov pauv thiab viscosity. Qhov no ua rau muaj kev faib cov cwj mem tsis sib xws, tsis txaus tus cwj mem, thiab pom qhov khoob hauv cov duab luam tawm.
- Kev cuam tshuam cov txheej txheem: Cov viscosity siab tsis tsuas yog ua kom cov number case ntau dua thiab ua rau cov xim number case thicker uas ua rau kom qhuav, tab sis nws kuj pab txhawb 背面沾脏 (cov number case set-off) los yog sticking ntawm cov ntawv luam tawm. Nyob rau hauv daim ntawv-fed luam ntawv, muaj kev pheej hmoo ntawm daim ntawv raug kos rau hauv tus number case rollers.
- Cov teeb meem viscosity tsawg: Hloov pauv, yog tias tus number case viscosity tsawg dhau, cov kua dej ntau ntxiv (ua kom pom tseeb dua) txhawb nqa tus lej emulsification hauv offset lithography, uas paug cov ntawv luam tawm nrog cov cim tsis xav tau.
- Tshaj tawm thiab txo kom pom tseeb: Cov ntawv zoo li no tau yooj yim kis rau ntawm daim ntawv, nthuav qhov chaw luam tawm, txo qhov pom tseeb, thiab txo qis qhov adhesion thiab gloss ntawm cov kua nplaum qhuav rau hauv cov substrate.
- Pigment Settling: Tsis txaus viscosity tawm tsam kom nqa cov xim loj dua thaum lub sij hawm hloov, ua rau cov khoom no mus rau hauv cov chais, pam vov, los yog daim hlau-ib yam mob hu ua piling.
