Cov thom khwm txawv yuav tsum tau tu cov tshuaj solvent txawv. Cov neeg ua hauj lwm tu cov tshuaj thiab cov tshuaj rau cov thawv, cov pam vov thiab cov pleev qhov pleev xim:
‧ Chemically sib xws
‧ Ib puag ncig thiab tshuaj lom
Ntxuav zoo
Cov kab hluav taws xob ntxhua khaub ncaws raws li kev lag luam, tab sis tshem tawm ntawm UV number case yuav tsum hnyav ncov qaum (glycol ether). Rau kev siv hom sib xyaw ua ke, muaj lwm yam kev sib txuas ntawm cov tshuaj (rau UV thiab cov pa hauv phom) - nws tseem tuaj yeem siv ob lub tshuab, ib qho UV thiab ib qho rau cov tshuaj ntxhua khaub ncaws. Non-classical UV (tov) yuav tsum tau muaj ib tus neeg tu neeg tu.
1 Siv cov kws kuaj mob thiab kuaj pom zoo xwb
2 Xyuas kom tseeb tias tus neeg saib xyuas kev kho mob yog siv hauv tus number case (xws li cov cim qub, UV number case, UV xyaw number case)
3 Nyob qhov twg muaj kev tsis ntseeg nyob rau hauv daim tshev compatibility ua ntej siv
Rau tag nrho cov ntawv luam tawm, qhov tseem ceeb tshaj plaws yog tsuas yog siv cov neeg ua haujlwm tu tsev uas tau saib xyuas los ntawm lub tshuab luam ntawv; tau pom zoo thiab Fogra-tsim nyog tu cov neeg ua haujlwm rau ntau hom phaj nias. Fogra kuaj cov compatibility ntawm cov neeg ua haujlwm tu nrog rubber rollers, pam vov, cov cuab yeej ntxuav thiab lwm qhov ntawm cov xovxwm. Cov khoom no muaj npe nyob hauv
Nyob ntawm cov khoom siv uas siv siv (printing, number case, pam thiab dov txheej), tu system (txhuam los yog ntaub tu tsev) thiab hom tshuaj ntxuav tes, nws tseem ceeb heev uas yuav tau xaiv txoj kev tu thiab kho lub sij hawm.
Cov luam ntawv uas siv tus qauv plaub-xim cuav uas muaj ob peb yam hloov tau pom tias kev sib xyaw ua ke yog txaus rau tus tu neeg sawv cev. Txawm li cas los xij, rau ntau cov qauv hauv thev naus laus zis thiab hloov ntau zaus, qee cov luam ntawv muaj ob lub thawv - ib daim pam pua chaw thiab lwm tus yog lub taub hau. Cov ntim ob qho no yog ib qho tseem ceeb nyob rau hauv ib nrab hnub-ib nrab kev ua ke uas cais cov UV ntawm daim pam ib qho thiab cov menyuam tu cov tshuaj.
Kev sib piv ntawm cov ntxhua khaub ncaws
Los ntawm kev sib piv ntawm tus tu neeg sawv cev ntawm tus neeg ua haujlwm, nws tuaj yeem pom tau tias tus tu neeg ntawm oily number case yog ib qho zoo heev, thiab cov nyhuv ntawm classic UV number case no kuj txaus siab. Kev ntsuas tshuaj tsis-classical UV (tov) tsuas ua tau rau cov neeg txom nyem los tsuas yog cov txiaj ntsig xwb - txawm li ntawd los, cov tshuaj ntxuav tau rau cov phev no yuav ua kom zoo dua.
Expansion experiment
Qhov kev yooj yim no qhia tau hais tias cov neeg txheeb xyuas kev ntxhov siab tuaj yeem swell cov khoom siv roj hmab. Peb cov qauv roj hmab tau raus hauv peb cov neeg ua haujlwm tu, thiab qhov ntse tau nce tawm ntawm sab laug mus rau sab xis. Tom qab 10 teev soaking lub sij hawm, tus qauv nyob rau hauv txoj cai test tube swelled heev, thaum sab laug sab tseem yuav luag tsis hloov.
Cov qhab-nees ntawm kev xeem yog ua tiav raws li hauv qab no:
‧ Naj Caj Nres: Siv lub tshuab ntxuav vaj tse feem ntau yog siv los ntxuav cov tu tsev tu neeg feem ntau kom ua tiav qhov zoo.
‧ Classic UV number case: Nws tuaj yeem tu tau sai thiab zoo nrog cov neeg tu tsev kho mob; UV number case yuav raug muab ntxuav nrog lub tshuab ntxuav khoom nrog lub tshuab ntxuav khoom, thiab tsuas yog ib qho kev ntxuav thiaj tuaj yeem tau cov txiaj ntsim zoo.
‧ Non-classical UV (mixed) inks: Cov tshuaj ntxuav cev los yog classic UV cuav kua mis tsis tsim nyog rau tshem cov phev los ntawm cov pam vov lossis cov thawv ntawv. Muaj cov kws kho mob tshwjxeeb tseemceeb rau UV inks, feem ntau ntawm cov roj zaub thiab muaj lub teeb nyem siab.
