kev loj hlob. Cov phom tawm tuaj yeem ua tsis tau thiab lub teeb tsa tseem tiaj tiaj, tiam sis nws muaj duab ntawm daim duab thiab cov ntawv nyeem ntawm daim phaj. Tom qab tsim nrog cov organic hnyav thiab txhuam nrog cov txhuam tshwj xeeb, cov teeb meem loj heev uas tsis tau yees duab los ntxuav thiab yaj hauv lub tshuab tank. Lub teeb pom kev zoo ntawm cov duab ci xim txheej yog cov polymerized thiab hardened, thiab tsis yaj los ntawm cov organic hnyav, kom lub phaj ntws muaj ib qho tsis zoo sib xws thiab ua ib lub phaj luam ntawv.
Lub sijhawm yaug dej yog qhov sib luag ntawm qhov tob ntawm qhov teeb tsa. Lub sij hawm ntev, lub nyem yog tob, thiab conversely, lub sij hawm yog luv luv thiab lub nyem yog ntiav. Nyob rau tib lub sijhawm, qhov ntev ntawm cov ntawv yoojyim yau yog qhov ncaj qha ntsig txog qhov kub ntawm tus tsim tawm, qhov ntev ntawm kev siv, thiab lub siab ntawm txhuam.
Nws tuaj yeem pom tias lub sijhawm yaug yog siv tau raws li ntau yam. Thaum lub sijhawm ua kom yoojyim, lub hau yuav qhib rau kev soj ntsuam. Thaum lub sij hawm yaug tsis txaus, lub hau npog yuav them thiab cov yaug yuav tau txuas mus ntxiv kom txog thaum uas yuav tsum tau ua tiav.
Kev npaj ntawm tus tsim tawm. Cov kaab nquag hab siv cov tshuaj kws siv huv huv yog: a) trichlorethylene lossis tetrachlorethylene; b) trichloroethane; c) n-butanol. Hauv kev npaj ntawm tus tsim tawm, cov organic solvents a) thiab b) yog cov neeg ua haujlwm tseem ceeb, thiab qhov sib piv rau c) yog 4: 1. Txawm li cas los xij, nws yuav tsum tau sau tseg tias qhov sib piv tsis yog qhov sib txawv ntawm qhov ntau, tab sis qhov ratio ntawm qhov kev nqus ntawm qhov hnyav. Tom qab kev daws teeb meem tiav lawm, nws cov qauv kev nqus yuav tsum yog 1.42Bé, uas ntsuas tau los ntawm ib lub ntsuas pa. Yog tias qhov kev daws teeb meem tshaj 1.42B, tus neeg sawv cev tseem ceeb ntau dhau lawm, txwv tsis pub tus neeg tseem ceeb yog tsis txaus.
Qhov tseeb piv ntawm qhov kev daws yog hais txog qhov ntev ntawm tus neeg tsim khoom siv, thiab ntau qhov tseem ceeb, nws cuam tshuam qhov zoo ntawm daim ntawv luam ntawv.
Qhuav (qhuav). Cov duab thaijsab teeb raug muab pov tseg rau hauv ib qho hnyuv ntxig los ua rau lub hau nqus dej los hnav, piv txwv tias, kom swell, thiab ua kom stickiness. Lub ziab no yog ntsuas tawm hauv qhov kub kub cua txias qhov cub ntawm qhov kub ntawm 60 ° C thiab lub sij hawm ziab ntawm 10-15 min. Lub ziab lub sij hawm ntawm lub thawv ntawv nrog rau cov phaj tuab yog txuas ntxiv. Qhov ziab feem ntau ua rau cov xim hnyav ua rau tawv nqaij los ntawm cov duab ci tuaj yeem ua kom rov tuaj yeem rov tuaj yeem txav mus rau hauv daim duab.
Tom qab ua tiav. Thiaj li yuav ua kom cov nplais ntawm lub phaj ntawv uas tsis yog tacky, cov nram qab no yog siv los de-stick qhov teeb tsa.
Illumination txoj kev. Siv luv luv-UV los taws lub phaj rau ib lub sijhawm luv luv ua tiav lub hom phiaj ntawm cov av tawm lub phaj.
Tshuaj txhaum cai. Siv cov tshuaj tov los ntawm cov tshuaj hydrochloric acid, dej, los yog xab npum, cov phaj ntawm lub phaj qoob loo yog qhov muag, thiab cov tshuaj yog nyob rau hauv cov kua xau kom tshem tawm cov dej khov. Tom qab ntawd yaug qhov seem ntawm lub phaj nrog dej thiab qhuav.
Hmoov hom. Thov ib txheej hlau uas magnesium carbonate los yog cov hmoov ntsej muag hmoov rau hauv cov phaj qoob los tshem nws. Hom no yog qhov yooj yim, lub sij hawm txuag thiab cov tswv yim, tab sis lub phaj yuav tsum yog hmoov tom qab kis tas.
Ncej raug. Daim ntawv cog lus ntawm daim ntawv cog lus muab tso rau hauv qhov raug ntaus nrog qhov teeb meem tshwm sim, thiab lub teeb ci tau ncaj qha mus rau yam tsis muaj lub tshuab nqus tsev, thiab raug rau lub sijhawm luv luv, yog li ntawd cov txheej txheem qis, nruab nrab thiab qis dua ntawm lub phaj yog ua kom tiav. Nws lub luag hauj lwm yog los ua kom qhov nyuaj ntawm qhov kev teeb tsa, ua rau kom cov ntawv pov thawj ntawm cov ntawv phaj; qhov thib ob yog los txhim kho qhov corrosion ntawm tus number case hnyav. Lub sij hawm ntev li no yuav ua rau cov nplai ntawm cov ntawv xov xwm tsis tshua nyuaj thiab txhawm rau txo lub zog ntawm cov ntawv phaj.
3 teeb meem tshwm sim thiab cov kev daws teeb meem hauv phaj vaj tsev
Cov nyhuv flexographic phaj ua tsis yog qhov yooj yim, tab sis nws muaj qhov zoo ntawm cov phaj, qhov zoo ntawm zaj duab xis tsis zoo, lub zog ntawm lub teeb ci, lub sij hawm raug, qhov qub thiab tshiab ntawm kev tsim kho, thiab lwm yam . Cov teeb meem zoo los yog seem.
Cov hom ills thiab ua rau cov phaj ua cov txheej txheem muaj npe hauv Daim Ntawv Qhia 1 rau kev siv.
4 txoj kev rau txuag cov ntawv nplais
Thaum cov khoom siv tshiab tshiab tau muab cia rau hauv lub tsev muag khoom, nws yuav tsum muab tso rau saum txee. Nws tsis muab tso rau vertically, txwv tsis pub nws yuav deformed thiab tsis tau stressed.
Thaum ua haujlwm qhib qhov rooj qhib, nws yuav tsum tsis txhob siv lub hnub ci los yog lub teeb meem tsis kaj siab thaum ua haujlwm hauv chav tsev nrog lub teeb daj. Thaum txiav, siv ib tug pas ntsuas thiab ib rab riam txiav kom hlais, los tiv thaiv qhov tseeb creases los yog shells. Tom qab txiav, qhov me me version ntawm version yog muab tso rau hauv lub thawv, thiab nws yuav tsum tau muab tso rau hauv ib qho. Tsis txhob muab tso rau sab sab kom tiv thaiv tau siv cov seem.
Tom qab luam ntawv, lub phaj yuav tsum tau muab ntxuav, pluas hmoov, qhwv hauv ntawv dub los yog kev tiv thaiv los ntawm lub teeb, khaws cia hauv qhov chaw qhuav thiab tsaus kom tiv thaiv tau cov phaj los ntawm tawv, txhav los yog tawg.
5 cov qauv zoo rau cov twj ywm los ntawm cov paib
Txawm hais tias tus txheej txheem luam ntawv, kev tsim tawm tshuaj ua rau muaj kev cuam tshuam zoo rau qhov zoo ntawm cov ntawv luam tawm. Dab tsi ntxiv, flexographic phaj txiav txim siab yog ib hom "zoo". Yog nws zoo los yog nws yog ib qho pov tseg. Nws tsis tuaj yeem tsim thiab kho nws hauv nruab nrab ntawm qhov teeb meem. Qhov no yog qhov loj tshaj plaws ntawm lub flexo. Tib lub sij hawm, nws tseem ceeb kom tsis txhob muaj teebmeem ntxiv ntawm kev luam ntxiv tom ntej no, thiab yuav tsum tau ua raws li cov qauv hauv qab no:
1. Lub phaj yuav tsum muaj qhov nyuaj. Nyob ntawm tus txheej txheem luam ntawv, lub hardness ntawm lub phaj ntawm lub phaj yog yuav tsum tau sib txawv. Lub ntim qhov dav ntawm Invar thawv muaj ib qho kev tshee hnyav txog li 30-35 degrees, thiab daim ntawv luam yas ntawm cov yas yeeb yaj kiab thiab cov ntawv muaj ib cov ntug dej ntawm 50-55 degrees.
2. Cov plaub fab ntawm lub phaj yog cov tsoog thiab cov tuab tuab tuab tuab. Lub tob ntawm lub nyem ntawm lub phaj yuav tsum txog 1/2 ntawm tuab ntawm lub phaj. Cov ntawv me me thiab qhov chaw me me muaj qhov tob.
3. Lub ntug ntawm cov ntawv nyeem thiab kab yuav tsum muaj ib txoj kab nqes, thiab qhov teeb tsa tsis nplaum.
4. Tsab ntawv, cov kab, daim teb, tsis muaj cov cwj pwm uas ploj lawm, cov kab tawg, xuab zeb qhov, qias neeg, thiab lwm yam.
5. Qhov luaj li cas ntawm cov ntawv phaj yog qhov tseeb, cov xim sib cais ntawm cov xim yog lawm, thiab hauv qab ntawm qhov kev txiav txim siab yog qhov ncaj.
6. Netted txheej version, lub siab thiab qis tshaj tawm tsis tuaj yeem ua poob, cov chaw ua haujlwm yog du, qhov chaw qis qis ntawm qhov chaw muaj me ntsis qhov tob.
