Kev ceev faj rau kev siv tshuab luam ntawv Rollers

* Printing rollers feem ntau hloov tus cwj mem ntawm offset printing presses. Yog li ntawd, kev tu txhua hnub ntawm cov menyuam yaus yuav tsum tau ua kom zoo. Txwv tsis pub, txheej txheej ntawm cov menyuam, nrog rau cov pigments thiab resin, yuav yooj yim oxidize, tsim ib tug du thiab tawv zaj duab xis, ua rau nto vitrification thiab cuam tshuam rau number case hloov. Yog tias tsis tu tsis tu ncua, lub ntsej muag ntawm cov menyuam yuav tsis sib npaug raws sijhawm, cuam tshuam rau kev siv. Yog li ntawd, cov rollers yuav tsum tau muab ntxuav thiab khaws cia kom zoo thaum lub tshuab nres.

* Thaum lub sij hawm offset luam ntawv, "dej ntau dhau thiab tus cwj mem" tuaj yeem ua rau tus number case emulsification, ua rau lub hauv paus hydrophilic ntawm cov menyuam du, ua rau tus number case deinking. Txoj kev daws yog tshem tawm cov emulsified number case, ntxuav lub deinked roller nrog roj av, thiab tom qab ntawd txhuam nws nrog kev sib xyaw ntawm 5% sodium hydroxide tov thiab pumice hmoov. Hlau rollers (los yog tawv rollers) yuav tsum tau kho raws li. Cov menyuam tawv tawv kuj tuaj yeem polished nrog cov ntawv ntub dej zoo thaum lub tshuab txau dej, tab sis kev saib xyuas yuav tsum tsis txhob nyob hauv ib qho chaw, txwv tsis pub cov menyuam yuav raug puas tsuaj. Qhov kev daws teeb meem tseem ceeb yog tswj hwm tus nqi pH ntawm cov kav dej thiab tswj cov dej kom zoo - tus lej sib npaug.

* Kev siv ntev ntev thiab kev laus ntawm cov menyuam roj hmab, ua ke nrog tshuaj lom neeg corrosion, tuaj yeem ua rau cov roj hmab tsis zoo thiab tawg. Xws li cov chais yuav tsum tsis txhob siv, vim lawv yuav cuam tshuam loj heev rau kev luam ntawv.

* Txhawm rau kom ntseeg tau tias tsis muaj kev cuam tshuam ntau lawm thiab luam ntawv zoo, cov ntawv ntim cov ntawv ntim khoom yog qhov tseem ceeb. Txawm li cas los xij, tsis txhob khaws ntau dhau los tiv thaiv kev laus. Qhov chaw cia rau cov menyuam roj hmab yog tib yam li cov pam vov. Tsis tas li ntawd, cov menyuam roj hmab yuav tsum tau muab khaws cia ncaj nraim ntawm phau ntawv xov xwm, thiab lawv qhov chaw yuav tsum tsis txhob kov ib leeg lossis lwm yam khoom los tiv thaiv kev deformation.

* Roj hmab rollers yuav tsum tsis txhob muab khaws cia ze ntawm lub tshuab hluav taws xob loj lossis lub tshuab hluav taws xob. Qhov loj ntawm ozone tsim los ntawm cov khoom siv no tuaj yeem ua rau cov menyuam nto hnub nyoog thiab tawg.

* Nyob rau hauv huab cua txias, yog tias tus number case tsis sib npaug, ntxiv cov khoom siv tsim nyog rau tus number case. Tsis txhob siv cov cua sov infrared lossis cov khoom siv zoo sib xws los ua kom sov cov kua nplaum, vim qhov no yuav tiv thaiv oxidation.
