Ib qho combo txav los daws qhov teeb meem ntawm kev ntxuav gravure rollers
Cov kws tshaj lij kev ua haujlwm hauv khw feem ntau hla qee cov tshuaj alkaline uas muaj zog los yog cov khoom hnyav hnyav kom muaj kev nyab xeeb ntau dua -tus phooj ywg, qis- tsw, thiab tiv thaiv roj hmab. Hauv kev tsim khoom, gravure roller clogs feem ntau yog tshwm sim los ntawm kev sib xyaw ntawm calcium crystals, dej qhuav - roj residue, thiab inorganic ntsev deposits, ua rau lawv nyuaj heev los ntxuav.
Dej thiab roj mesh cov menyuam ua ntej ntxuav
Cov dej huv huv -Oil Roller
Raws li cov txheej txheem tshuaj, tus nqi qis - ua ke ntawm "lub tsheb ntxuav dej + ntxhua khaub ncaws ntxhua khaub ncaws + nylon txhuam" tuaj yeem siv los daws cov teeb meem ntxuav dej- roj chais.
Txoj Cai Ua Haujlwm
01 / Khaub Ncaws Khaub Ncaws (Cov Khoom Tseem Ceeb: Sodium Carbonate / Phosphate)
Laundry detergent yog heev alkaline. Raws li kev lag luam tu cov hauv paus ntsiab lus, alkaline cov neeg sawv cev (xws li sodium carbonate) tuaj yeem ua kom cov roj hydrolyze zoo, tshwj xeeb tshaj yog rau cov av tawv tawv uas tau tsim dhau sijhawm; lawv cov kev nkag mus thiab emulsifying muaj peev xwm yog qhov zoo tshaj rau cov tshuaj ntxuav tes tsis zoo.
Tsis tas li ntawd, cov khoom siv ntsev hauv cov tshuaj ntxuav tes ua kom muaj kev sib txhuam thiab tawg, pab kom tshem tawm cov av tob hauv cov menyuam mesh grooves.
02/ Lub Tsheb Ntxuav Dej / Ntxuav Tshuaj (Organic Solvent)
Cov dej ntxuav tsheb feem ntau muaj cov kuab tshuaj muaj zog uas tuaj yeem ua rau cov tawv tawv tawv thiab cov dej kho tsis tiav - cov khoom siv roj.
03/ Nylon Txhuam (lub cev txhuam)
Ua ke nrog cov tshuaj tua kab mob, txhuam lub cev yog qhov tseem ceeb rau kev tshem tawm cov mesh. Nco ntsoov tias txhuam nylon tsis zoo heev; txhuam tooj liab tuaj yeem siv tau (nrog lub zog quab yuam), tab sis rau siab - precision ceramic mesh rollers, tseem muaj kev pheej hmoo ntawm khawb.
"Cov cheeb tsam txwv"
Txawm hais tias txoj kev no ua haujlwm tau zoo, thaum tu Heidelberg cov khoom siv luam ntawv, uas yog cov tshuab ua kom raug, yuav tsum tau ceev faj hauv qab no:
01/ Tsis txhob siv Ethanol
Tsis txhob siv ethanol los yog cov kuab tshuaj organic los ntxuav qhov precision zoo li cov menyuam roj hmab, thiab tsis txhob sib xyaw ethanol thaum ntxuav dej - roj chais. Ethanol evaporates sai, muaj hnub nyoog thiab tawg roj hmab, thiab yog flammable.
02/ Tiv thaiv roj hmab Corrosion
Cov khoom muaj zog alkaline hauv cov ntxhua khaub ncaws ntxhua khaub ncaws (xws li cov poov tshuaj lossis sodium hydroxide) tso rau ntawm qhov chaw tuaj yeem ua rau cov menyuam yaus corrode, txo cov roj affinity, thiab tseem ua rau crystallization, cuam tshuam tsis zoo rau cov dej tom ntej - roj uniformity.
03/ Tiv thaiv Hlau Corrosion
Yog tias cov tshuaj alkaline muaj zog tsis tau muab yaug kom huv si, nws tuaj yeem ua rau cov hlau chais lossis cov kabmob.
Txoj kev Optimization suggestion
Txhawm rau ua kom huv si zoo thaum txuas cov cuab yeej siv lub neej, ua cov kev hloov kho hauv qab no:
01/ Siv Soaking Method rau "Lub Tsheb Ntxuav Dej + Khaub Ncaws"
Dissolve ntxhua khaub ncaws hauv dej sov thiab ntxiv me me ntawm cov dej ntxuav tsheb. Tsis txhob txhuam nrog xab npum ncaj qha rau ntawm cov menyuam, vim tias qhov concentration siab dhau thiab tuaj yeem ua rau cov roj hmab puas.
02/ Ntshai thiab yaug tom qab txhuam hniav
Tom qab txhuam hniav, yaug kom huv si nrog dej huv kom ntau kom txog thaum tsis muaj kev ntxhib los mos lossis ua npuas dej.
03/ yeem Acid Neutralization
Yog tias muaj kev txhawj xeeb txog qhov seem alkalinity, koj tuaj yeem so sai sai rau cov menyuam nto nrog cov kua qaub kua qaub (acidic) kom tshem tawm cov tshuaj alkaline, tom qab ntawd yaug nrog dej huv kom tsis txhob muaj cov nplaum los yog crystallization.
04/ Siv cov txhuam hniav kom zoo
Paub meej tias cov khoom siv mesh cov menyuam-txawm nws yog chrome-plated lossis ceramic. Rau cov menyuam yaus ceramic, tsis txhob siv cov txhuam hniav hlau (xws li tooj liab); tsuas yog siv cov nylon txhuam. Copper txhuam yuav siv tau rau lwm hom, tab sis siv lub teeb quab yuam kom tsis txhob khawb.
Qhov tseem ceeb, cov qauv no tso siab rau kev sib koom ua ke ntawm "muaj zog alkali (ntxhiab ntxhua khaub ncaws) + hnyav (lub tsheb ntxuav dej) + kev sib txhuam ntawm lub cev (nylon txhuam)" los daws cov av tawv.
