Kev daws teeb meem ntawm Printing Press Sink Fluid
Sep 12, 2021
Tshawb nrhiav cov teeb meem tshwm sim ntawm cov luam ntawv xovxwm dab dej-Qhov concentration ntawm cov dej hauv lub dab dej uas tsim nyog yog nyob ntawm tus nqi conductivity. Thaum cov conductivity siab dhau lawm, tus number case yuav tsis yooj yim kom qhuav, thiab yog tias cov conductivity tsawg dhau, nws yuav yooj yim rau stain los yog khaws cov number case. Yog li koj yuav tsum sim nrhiav qhov tsim nyog tus nqi conductivity. Tom qab nrhiav tus nqi concentration, muab tag nrho lub tank ntim los ntawm feem pua los ua thawj qhov sib ntxiv. Tsis tas li ntawd, thaum tus nqi conductivity hloov ntau dua ± 50 ~ 100, koj yuav tsum tau kho ua ntej koj tuaj yeem siv nws txuas ntxiv. Nyob rau tib lub sijhawm, koj yuav tsum tau them sai sai rau qhov ntsuas kub hauv lub tank dej, vim tias qhov ntsuas kub yuav cuam tshuam rau qhov ntsuas tus nqi ntawm cov khoom siv hluav taws xob.
Feem ntau pom zoo rau cov dej luam ntawv zoo tshaj plaws yog:
(1) Cov dej zoo yuav tsum yog dej mos;
(2) Tus nqi conductivity yog 700 ~ 1300 (tus nqi conductivity ntawm dej yuav tsum tau txiav tawm);
(3) PH nqi 4.0~5.5;
(4) Qhov kub ntawm lub tank dej yog 5 degree ~ 15 degree;
(5) Cov degree ntawm emulsification yog qis dua 35 feem pua;
(6) Qhov feem ntawm cawv IPA yog 5 feem pua ~ 15 feem pua;
(7) Qhov sib piv ntawm cov kua tank yog 1.5 feem pua ~ 2.5 feem pua.
Cov hauv qab no yog cov qhabnias tiag tiag ntawm qhov chaw hauv lub chaw luam ntawv:
Lub tog raj kheej: Khawv koob 150
Conductivity Meter: Delta OHM Conductivity Meter Model: HD 8706
PH Meter: HANNA PH Meter Model: HI 8521
Raws li cov piv txwv saum toj no, tag nrho cov nyiaj ntawm 80,000cc * 2 feem pua =1,600cc ntawm lub tank dej ntawm lub tshuab luam ntawv nyob rau hauv central printing laboratory muaj tus nqi conductivity ntawm 1,000 (1,095-92.5) ± 100 thiab pH tus nqi kwv yees li 5.0. Tsis tas li ntawd, peb pom tias tus nqi pH tsis hloov pauv ntau tom qab qhov concentration ntawm cov tshuaj tank yog 3 feem pua, yog li nws tsis yooj yim los xyuas seb tus nqi puas tsim nyog, thiab qee qhov European tank kev daws teeb meem muaj ntau qhov buffers ntxiv, thiab lawv txoj haujlwm. yog kom muaj kev ruaj ntseg ntawm lub tank tov. Lub acidity thiab txo qhov corrosion ntawm cov txheej txheem yuav ua rau muaj teeb meem thaum siv tus nqi pH los ntsuas qhov concentration ntawm cov tshuaj da dej.
