Kev tsim nyog tswj ntawm kev siv tshuaj tsis haum nyob rau hauv kev luam cov txheej txheem luam tawm tuaj yeem tiv thaiv thiab daws tau ntau yam teeb meem luam tawm, feem ntau nrog cov nyhuv txig, koj xav sim.
Tus nqi ntawm dampening kua additive yuav tsum tau ruaj khov. Kev ntsuas cov ntsuas yuav tsum muaj cuab yeej kho tau rau cov ntawv ntxiv. Lub tank tsis siv tshuaj ntxiv yuav tsum tau soj xyuas tsis tu ncua thiab tswj xyuas kom muaj kev lag luam ntawm cov khoom siv hluav taws xob. Qhov kev kuaj sim yog siv los tswj tus nqi dampening kua additive ntxiv. Ua ntej, cov tshuaj ntawm cov dej huv yuav tsum ntsuas. Hauv kev xyaum, cov kev coj ntawm cov dej huv yuav tsum raug txiav tawm. Vim haus dej cawv los yog haus cawv tsis yog kev qhia, kev sib txuas lus yuav txo tau tom qab sib ntxiv. Yuav tsum ntsuas cov kab mob tom qab ntxiv cawv.
Dej: Lub ntsiab ntawm cov kua dampening yog dej. Dej haus zoo txawv ntawm qhov chaw mus rau qhov chaw. Feem ntau, cov dej uas muag muag muaj qhov sib xyaw ntawm 0-225 μs, thiab cov dej kub feem ntau muaj qhov kub txog 450 μs los yog ntau dua. Thaum twg cov dej tsis zoo (tshwj xeeb tshaj yog thaum Ca + cov ntsiab lus siab), nws feem ntau ua rau Ca + mus cuag cov khoom nyob rau hauv tus cwj pwm rau daim kab ntxwv saponified calcium. Thaum ua ke nrog cov kua qaub nyob hauv cov kua txob acidic, nws yuav ua cov calcium uas yog calcium los yog calcium phosphate. Ntsev li ntawd. Cov kua txig ua kua txig muaj lipophilicity, uas ua rau tus cwj mem ntim rau hauv qhov chaw xws li dej rollers thiab inking rollers, ua rau saum npoo ntawm cov yas rubber rau crystallize, uas ua rau cov dej tsis hloov thiab hloov cwj; thiab calcium ntsev yog hydrophilic, uas hinders tus number case. Kev hloov thiab ua rau tus cuav quav rau tus dej, ua rau lub dampening solution additive siv thaum cov dej yog cov dej tawv yuav tsum muaj cov tshuaj coj los tiv thaiv tus cawv ntawm cov calcium uas ntau heev.
Lub lithographic phaj yog raws li lub hauv paus ntsiab lus ntawm incompatibility, wetting, adsorption thiab selective adsorption ntawm roj thiab dej. Duav nyiaj seem yog qhov tseem ceeb tshaj plaws ntawm lithographic offset printing. Kev tsim nyog tswj thiab kev siv tshuaj dampening yog ib qho tseem ceeb hauv kev lithographic offset luam ntawv. Tsab ntawv no yuav siv cov ciav dej ciav dej uas tam sim no siv tam sim no ua piv txwv. Los ntawm cov qauv ntawm cov lus sib xyaw thiab daim ntawv thov ntawm cov ciav kua, nrog rau tus kws sau ntawv cov kev xyaum luam ntawv xyaum, tham txog kev tswj kev siv tshuaj dampening.
Cawv lossis haus cawv hloov chaw: Lub luag haujlwm tseem ceeb ntawm kev haus dej cawv nyob hauv kev sib tw yog kom txo qhov nrawm ntawm qhov kev sib tov dej. Lub volatility ntawm cov cawv yuav txo qhov emulsification ntawm tus number case, khaws cov xim ntawm cov khoom luam ci thiab txhawm rau ziab ntawm tus number case nyob rau hauv lub substrate. Txij li isopropanol tau muaj qhov qis qis qeeb, muaj peev xwm los txo qhov nro qhov dej nrawm dua, thaum muaj cawv muaj ntau dua thiab muaj peev xwm txo qis ntawm qhov dej nruj, thiab qhov zoo tshaj plaws ntawm isopropanol feem ntau ruaj khov. Tam sim no, qhov zoo thiab tus nqi ntawm cov cawv khoom muag nyob rau hauv lub lag luam yog txawv. Thaum siv, cov khoom muaj purity thiab zoo nkauj yuav tsum tau ua tib zoo xaiv. Siv isopropyl cawv ntau li ntau tau. Tsis txhob siv cov cawv muaj cawv, uas tuaj yeem txo cov tshuaj, ua kom siv cov khoom zoo thiab cov khoom zoo, thiab txo nqi.
Feem ntau, qhov chaw nruj ntawm dej kais dej yog li 72 thaj chaw, thiab qhov nro ntawm cov xim tawm ntawm sab nraud yog 30 txog 36 lub vaj tsev. Qhov nro ntawm qhov sib txawv ntawm cov ciav hlau yuav tsum raug tswj kom zoo ib yam li cov teeb meem ntawm qhov tob, kom ob leeg muaj kev sib npaug thiab ruaj khov. Tswj lub degree ntawm emulsification ntawm tus number case. Feem ntau, cov isopropyl cawv ntsiab lus yuav yog li 8% mus rau 12%, thiab cov dej cawv yuav tsum tsis txhob siab heev, txwv tsis pub tus number case yuav muaj tiag emulsified.
