Lub ntim yog ib hom kua nplaum zoo li cov nplaum nrog qee yam fluidity. Viscosity, flexion tus nqi, thixotropy, fluidity, dryness, thiab lwm yam txhua yam txiav txim siab qhov kev ua haujlwm ntawm tus number case.
Viscosity: Nws yog cov cuab yeej uas tiv thaiv qhov ntws tawm ntawm cov kua dej. Nws yog ntsuas ntawm lub peev xwm ntawm cov kua dej lwg me me kom ua rau qhov cuam tshuam ntawm kev txav nruab nrab ntawm cov lwg me me, uas yog, qhov tsis kam ntawm cov kua dej ntws tawm. Lub viscosity ntawm tus number case muaj kev sib raug zoo nrog kev hloov pauv ntawm tus number case thaum lub sijhawm luam ntawv thiab cov khoom thiab cov qauv thiab qauv. Yog tias qhov viscosity ntawm tus number case loj dhau, kev hloov pauv ntawm tus number case thaum lub sijhawm luam ntawv tsis yooj yim rau kev niaj hnub zoo li tsis sib xws, thiab qhov tshwm sim ntawm fuzzing daim ntawv tshwm sim, uas ua rau lub teeb paj; Tsawg heev, tus number case yog yooj yim rau emulsify, tau qias neeg, thiab cuam tshuam rau qhov zoo ntawm cov ntawv luam tawm. Hauv cov txheej txheem luam ntawv, qhov yuav tsum tau ua ntawm number case viscosity yog nyob ntawm yam tseem ceeb xws li kev nrawm ntawm kev luam ntawv luam ntawv, qhov kev hloov ntawm pej xeem software ntawm daim qauv ntawv, thiab kev hloov pauv ntawm qhov kub thiab av noo nyob ib puag ncig.
Yield tus nqi: hais txog qhov txav yam tsawg kawg nkaus uas yuav tsum tau ua kom cov kua pib ntws. Yog tias tus number case yield tus nqi ntau dhau, qhov fluidity yuav tsis zoo thiab nws tsis yooj yim qhib, thiab yog tias tus nqi tawm tsis dhau, cov dots thaum luam ntawv yog nquag halo thiab ua rau cov ntawv luam tawm tsis meej. Qhov loj ntawm cov pa tawm muaj feem cuam tshuam nrog tus qauv tsim ntawm number case, muaj kev cuam tshuam ncaj qha rau kev npliag ntawm tus number case, thiab yog qhov ntsuas qhov tseem ceeb rau qhov ua tau zoo ntawm kev them nqi thiab cov lej sib tsoo. Feem ntau hais lus, cov xim lo lus ntawm tus number case nce thiab tus naj npawb nce, thiab qhov quab yuam thiab viscosity uas tabkaum cov kua ntws yuav tseem nce ntxiv. Piv txwv, inks ntawm letterpress printing thiab lithography siv hauv ntim luam ntawv muaj ntau ntawm cov xim, thiab lawv cov zog yuav tsum tau ntau dua li qhov muaj nuj nqis kom txaus. Yog li ntawd, qhov kev quab yuam ntawm tus number case yuav tsum muaj ntau dua qhov tus nqi kom ntws tawm, thiab tus nqi no yog tus nqi tawm ntawm tus number case.
Thixotropy: Nws hais txog qhov tshwm sim uas tus number case hloov ntawm tuab mus rau nyias nrog qhov kev txiav txim siab thaum nws tau sib zog los ntawm sab nraud quab yuam, thiab tom qab ntawd rov mus rau qhov qub qub tom qab qhov kev txiav txim siab nres. Vim yog qhov thixotropy ntawm tus number case, tom qab tus number case raug rau kev sib hloov ntawm cov ntawv luam tawm ntawm tus number case hlau, nws yuav nce qhov fluidity, nce ductility, thiab ua rau tus number case yooj yim rau hloov; thaum tus number case hloov mus rau daim ntawv tom qab luam ntawv, nws poob qhov tshwm sim ntawm sab nraud quab yuam, Tus number case hloov ntawm thinning mus rau tuab yam tsis muaj ib puag ncig, ua rau luam tawm zoo. Yog hais tias qhov thixotropy ntawm tus number case loj dhau lawm, tus cwj mem hauv tus number case yuav tsis yooj yim tig, uas yuav cuam tshuam tus number case hloov chaw ntawm tus number case rau cov menyuam.
Qhov npliag: Nws txhais tau hais tias tus number case yuav ntws zoo li cov kua hauv nws qhov hnyav, uas yog txiav txim siab los ntawm cov viscosity, tawm tus nqi thiab thixotropy ntawm tus number case, thiab nws kuj hais txog qhov kub thiab txias. Kev hloov pauv ntawm tus number case cuam tshuam txog seb tus number case tuaj yeem nchuav los ntawm lub thawv ntim, thauj los ntawm tus number case cia lub thawv kom tus number case ntws ntawm lub tshuab luam ntawv luam, du hloov los ntawm tus number case ciav, zoo faib rau ntawm lub tshuab luam ntawv, hloov mus txheej thau thiab hloov mus rau ntawm lub substrate, nws kuj cuam tshuam cov nyhuv ntawm luam ntawv.
Qhov ntev ntawm tus number case filament: hais txog qib uas tus number case pib chiv rau hauv ib qhov chaw tsis tawg. Nws qhov ntev yog cuam tshuam nrog qhov thixotropy, cov nqi tawm thiab cov yas viscosity ntawm tus number case. Ink nrog luv number case filaments yog tus cwj mem nrog kev luam ntawv ua tau zoo hauv kev pab txhawb kev luam ntawv thiab ntawv luam ntawv, thiab yuav tsis ua rau tus cwj mem ya hauv cov txheej txheem luam ntawv. Nyob rau tib lub sijhawm, txheej txheem number case ntawm qhov teeb meem luam tawm kuj tseem zoo ib yam thiab tuab. Qhov ntev ntawm tus number case filament yog ib txoj kev niaj zaus los ntsuas qhov ua tiav ntawm tus number case.
Siv qhuav ntawm number case: Kev ziab qhuav yog hais txog cov txheej txheem ntawm kev hloov los ntawm cov kua los yog cov muab tshuaj txhuam rau cov zaj duab xis tom qab tus cwj mem ua raws li cov ntawv luam tawm los ua tus luam. Tus txheej txheem no yog kev hloov pauv ntawm kua los yog muab tshuaj txhuam rau qhov khoom siv ntug hauv tus number case Khoom thiab ua tiav. Vim tias cov hlua khi siv ntau yam inks thiab lawv cov qauv sib txawv, cov txheej txheem kom qhuav ntawm cov inks kuj sib txawv. Tom qab tus cwj mem tau hloov los ntawm luam ntawv phaj mus rau saum npoo ntawm cov khoom luam tawm, ib feem ntawm cov khoom sib txuas hauv tus number case nkag, thiab cov kuab tshuaj nyob hauv cov khoom txuas tseem pib ua kom tsis huv. Qee cov ntaub ntawv sib txuas pib tsim cov tshuaj los yog tshuaj rau lub cev, yog li ua rau tus cwj mem luam tawm nyob rau sab npoo ntawm cov substrate. Cov txheej maj mam nce nws cov viscosity thiab hardness, nws thiaj li ua ib zaj duab xis. Feem ntau, nyem inks yog mas permeable kom qhuav, lithographic offset luam ntawv inks yog mas oxidized conjunctival kom qhuav, thiab gravure luam ntawv inks yog mas tsis tshua muaj neeg kom qhuav vim lawv siv ntau yam tsis mloog hais daws tshuaj li khi.
