Khiav tov khoom npaj
1. Ntsuas kev xav
Cov kua dej dampening yog loj heev, yog li ntawd tus nqi pH ntawm dampening kua me me, yuav ua kom sib cais ntawm tus cwj mem (kev sib txuas ntawm cov khoom sib txuas thiab cov pigment), uas ua rau tsis siv dej tsis siv, ua rau muaj suab thaj tsos nqaij daim tawv, thiab qee zaus muaj kev phom ploj phenomenon, thiab nce tus nqi dej. Kev ploj phaj plhu tshwm sim ntau dua; Yog hais tias cov khoom ntawm dampening kua tsawg dua, qhov pH ntawm dampening kua yuav ua loj dua, thiab cov txheej txheem hydrophilic ntxiv rau seem ntawm daim ntawv phaj yuav tsis txaus los tiv thaiv cov hlab xaj ntawm tus cwj pwm, ua rau muaj cov dej loj siv nyob rau hauv lub phaj luam ntawv. Tshooj thiab xim hloov ntawm tus number case. Piv txwv, cov ntawv luam tawm yog qhov loj qhov loj ntawm qhov chaw gradient. Thaum lub sij hawm luam ntawv, qhov gradient dot yog maj maj, tus number case xim yog qhov muag, thiab nws yog ib qho kev ua qias neeg. Tom qab cov dej tau noj lawm, qhov teeb meem yog tsis daws, yog li lub tshuab kaw tam sim ntawd thiab ntxuav nrog tus tu neeg sawv cev. Tshooj, ntsuas qhov pH ntawm cov kua dampening yog 6.0, kho qhov ntau ntau ntawm cov dampening kua, thiab txo tus nqi pH ntawm dampening kua mus txog 5.0, qhov teeb meem yog daws tau.
2. Muab cais tawm
Hloov kev dampening kua, los yog kho cov khoom ntawm dampening kua los tswj cov pH ntawm dampening tov rau 5.0 ~ 5.5.
Cawv sib ntxiv

Cov dej cawv ntxiv yog ib qho loj heev, txawm tias nws tuaj yeem txo qhov dej nro, ua dej thinner dej, thiab muaj kev sib txuas zoo (piv txwv li, kev sib kis) rau saum npoo ntawv, tab sis nws yuav ua rau haus dej cawv dej tuaj yeem ua haujlwm nrog cov kev sib tov khoom, ua rau muaj kev zoo nkauj. Qhov tshwm sim ua rau cov dej loj thiab tus cwj mem kua thooj. Ntawm qhov tsis sib xws, qhov tsis txaus ntawm feem cawv yuav ua rau muaj qhov kub nruj ntawm cov dej kom siab, thiab qhov ua rau lub qhov teeb meem tsis zoo. Tus nqi ntawm cov dej yuav tsum tau nce kom ua tus number case tsis lo av, yog li cov xim muaj xim tsis zoo. . Piv txwv li, ib qho luam ntawv thiab ntim ntawv, vim tias tsis muaj cawv cwj pwm tau siv lawm, ua rau txo cov dej cawv los ntawm 6%, qhov tshwm sim ntawm kev qias neeg, tom qab nce dej, qhov nqig version ploj, tab sis cov xim ntawm tus cwj pwm hloov maj mam hloov, nres xyuas, tswj qhov rai dampening Nws qhia tau hais tias cov dej cawv ntsiab poob qis dua 6%, thiab haus dej cawv yog hloov los ua cov dej cawv ntsiab lus txog 10%. Thaum pib luam tawm, dej tau muab txo mus rau yav dhau los, thiab tsis muaj cov kab ntawv qias neeg thiab tus cwj pwm xaj yog qhov qub.
2. Muab cais tawm
Tswj cov dej hauv dej tank kom lub txiaj ntsig dej cawv muaj raws li qhov nqi tiag tiag. Qhov dej cawv piv yog 10% mus rau 14%; Isopropyl cawv chaw piv yog 8% mus rau 13%.
Dej hardness

Lub zog ntawm dej yog siab, thiab cov calcium oxide, magnesium oxide thiab cov zoo li hauv cov dej yog kis mus rau saum npoo ntawm tus cwj mem kua hauv plawv nrog cov tshuaj Cheebtsam hauv tus cwjpwm, ntawv hmoov thiab cov hmoov av, uas ua rau tus number case roller deinking thiab number case hloov tsis tau, thiab cov tshuaj no muaj cov roj fatty acid kuj ua rau cov alkalinity ntawm tus cwj pwm kom nce, uas yog yuav ua ib qho kev tshwm sim paste thiab ua kom muaj suab ntawm cov cwj mem. Piv txwv, kev siv dej ntev nrog kev sib tw ua kom yooj yim ua rau kom yooj yim ua rau cov kauv caj dab tuaj yeem ua kom nrov, ua rau cov quav caws quav rau kob. Cov ntawv luam tawm tau pom cov dej loj thiab ib tus qauv dej (tsuas yog thaum cov ntawv luam tawm tsawg dua, yog tias tus cawv piv tsis tshua muaj, Qhov tshwm sim no tshwm sim, ua rau muab tshuaj txhuam, cov pa phem, cov khoom luam tawm tau tsaus nti, thiab yooj yim thaiv lub tank dej.
2. Muab cais tawm
Kev siv cov dej demineralized txo cov dej, ua cov dej thinner, tsis yooj yim rau kev sib tsoo, thiab cov gloss ntawm cov ntawv luam tawm yog nce, thiab cov tawv nqaij ntawm cov quav cuav quav kuj raug txo.
Tshuaj tsis haum hloov lub sij hawm
1. Ntsuas kev xav
Vim lub sij hawm ntev dua ntawm cov tshuaj tsis haum, cov kab mob hauv cov dampening kua yuav ntau dhau, ua rau lub dampening tov rau deteriorate, ua rau tsis ruaj tsis khov dej thiab cov xim ntawm lub cwj mem. Piv txwv li, thaum luam ntawv plaub npog tag nrho, qhov kev kuaj xyuas tau pom tias tus lej ntawm ob qho tib si ntawm daim luam tau raug rho tawm. Qhov kev soj ntsuam pom tias qhov layout ntawd tseem heev ntub, thiab nws tau xaus tias cov dej tau qeeb dhau los ua rau lub phaj ntub kom qeeb qeeb. Tshawb xyuas qhov dej ntawm cov dej hauv plawv yog qhov qub, tom qab txo cov dej haus, nruab nrab qias neeg phaj, tom qab kev ntsuam xyuas, tej zaum yuav ua rau cov kua dampening tsis tau hloov ntev, ua rau lub dampening tov los qub, dej yeeb yaj kiab los ua tsis pom kev. Tom qab hloov cov dej hauv lub tank, daim ntawv luam tawm ntawm cov ntawv luam tawm yog qhov qub.
2. Muab cais tawm
Cuam tshuam cov tshuaj tsis haum rau hauv lub tank. Nruab ib lub raj xa dej ntawm lub tank tso dej thiab txuas lub tank dej rau lub tshuab lub raj xa dej los ntxuav lub tank kom sai. Yog tias cov ntaub qhwv npog pov tseg ntawm qhov chaw nres nkoj xa dej kom cov dej nyob hauv lub taub dej huv, nws tuaj yeem tiv thaiv tau cov dej xa tuaj mus ntev.
