Hauv kev xa ntawv luam tawm, lub npe "dej-ziab" txhais tau hais tias lub tsho ntawm daim ntawv luam tawm tsis tsim cov dej haus zoo txaus, uas yog, tsis yog daim duab ntawm lub phaj ntawv tsis txaus hauv dej. Thaum cov phom luam ntawv qhuav lawm, nws yuav ua rau lub voj voos ntawm cov ntawv xov xwm ua qias, uas yuav cuam tshuam qhov zoo ntawm cov ntawv luam tawm, uas yog hais, tus number case thiab dej tshuav nyiaj li cas yuav tsis tawm ntawm kev tswj lub sijhawm luam ntawv .
Tus tswj ntawm tus lej tshuav nyiaj muaj feem xyuam nrog ntau yam, xws li kev sib piv ntawm cov ntim ntawm ntim thiab dej ntim, qhov zoo ntawm dampening kua rau nws tus kheej, qhov concentration ntawm dampening kua, qhov nyiaj thiab kub ntawm cawv, qhov xwm ntawm tus cwj pwm nws tus kheej, lub siab ntawm tus cwj mem zas xim rau tus kheej, qhov kub thiab txias. Tos.
Yog tias cov tshuaj tsis haum thiab cov dej cawv siv nyob rau hauv cov txheej txheem luam ntawv, yog vim li cas rau lub phij xab "drying" yuav yog qhov uas muaj tus cwj pwm plawg thiab cov dej ciav dej kom tsis raug teeb meem, thiab tej zaum kuj yog siv nrog dampening tshuaj siv nyob rau hauv cov txheej txheem luam ntawv. Kev txheeb zoo.
Yog hais tias lub siab ntawm cov tub ceev xwm thiab cov ntawv xov tooj ntawm cov xaim npau suav yuav tsum yog qhov teeb meem, qhov tshwm sim ntawm "ziab" tseem muaj tshwm sim, uas yuav tshwm sim los ntawm qhov chaw siab ntawm qhov dej ntawm cov kav dej. Kev tsis txaus siab ntawm cov dej yob tuaj yeem yooj yim ua rau plab phenomenon qhuav. Tsis tas li ntawd, yog muaj roj rau ntawm cov dej hauv cov dej, nws yuav cuam tshuam txog dej ntim ntawm cov dej hauv dej, uas ua rau "dej qhuav" tsis ua haujlwm ntawm cov ntawv phaj.
Txawm hais tias cov nyiaj dampening kua thiab cawv siv nyob rau hauv cov txheej txheem luam ntawv yog tsim muaj tseeb, nws tsis txhais tau tias qhov zoo ntawm dampening tov yog ruaj khov. Cov tshuaj tsis haum yuav tsum muaj cov khoom ntim rau pH, phaj tiv thaiv, wetting, anti-corrosion, bactericidal thiab anti-foam zog. Qhov tsis nyob hauv kev dampening kua mas yog kev tswj hwm lub pH ntawm dampening kua, vim hais tias cov tshuaj tsis haum yog feem ntau cov kua qaub, thiab cov pH ntawm dampening kua yuav hloov tau zoo heev nrog qhov sib ntxiv ntawm qhov tsis tuaj yeem. Tsis tsim nyog yuav cuam tshuam rau cov khoom siv roj av ntawm lub phaj. Cov cuab yeej tiv thaiv ntawm lub phaj ntawv txhais tau hais tias cov khoom ntim ntawm cov ntawv luam tawm yog kev tiv thaiv. Yog tias nws raug siv tsis zoo, cov khoom ntim ntawm cov ntawv luam ntawm lub tshuab luam tawm kuj tau qis, thiab qhov tshwm sim ntawm "ziab" tshwm sim. Lub fungicide tiv thaiv algae thiab microorganisms los ntawm kev loj hlob nyob rau hauv cov dej ncig zog thiab tsis txhob txhaws ntawm lub raj xa dej. Tus neeg ua hauj lwm tiv thaiv kev tiv thaiv ua rau cov neeg ua hauj lwm tiv thaiv tsis pub hnav cov khaub zig tawm hauv cov dej tank thiab tsis yoojyim rau cov phom luam ntawv.
Yog li, thaum muaj qhov "ziab" tshwm sim thaum lub sij hawm xa ntawv luam tawm, nws yog thawj qhov xyuas seb qhov teeb meem ntawm lub khob ntawm cov tub rog thiab cov dej ntawm cov dej yog qhov tseeb, thiab ntxuav cov kav dej kom tsis tu ncua. Ntxiv rau qhov no, nco ntsoov siv cov ciav dej zoo. Thaum xaiv cov dampening kua, nws yuav tsum ua ke nrog dej zoo thiab lwm yam kev mob ntawm lub hoobkas. Nrawm kom tswj tau cov tshuaj tsis haum, cov isopropanol (cawv) thiab cov pH ntawm dampening kua. Thiab cov yeeb yam xws li kev coj ua.
Nws tuaj yeem pom los ntawm kev soj ntsuam saum toj no uas ntxiv nrog rau cov ntawv xov xwm, tus number case supply thiab cov zoo li, cov tshuaj tsis haum yog qhov tseem ceeb tshaj plaws rau qhov tshwm sim ntawm "dej qhuav" tsis ua hauj lwm hauv kev lag luam luam ntawv, txawm tias kev haus dej cawv thiab ntau npaum li cas cov tshuaj tsis haum dampening nyob rau hauv txoj kev dampening. Cov chaw muaj tseeb thiab yuav ua rau "ziab" vim lwm yam.
