UV nplaum yog ntxiv photoinitiator (lossis photosensitizer) rau cov resin nrog cov mis tshwj xeeb.Tom qab absorbing lub siab siv ultraviolet lub teeb nyob rau hauv lub ultraviolet (UV) curing khoom, nws yuav tsim active dawb radicals los yog ionic radicals, thiaj li yuav pib polymerization, cross-linking thiab grafting tshua, thiaj li hais tias cov resin (UV txheej, number case, nplaum, thiab lwm yam) tuaj yeem hloov los ntawm cov kua mus rau cov khoom hauv ob peb vib nas this (nruab nrab).Qhov kev hloov pauv no hu ua "UV curing".
1, Qhov zoo ntawm UV nplaum:
1. Cov nplaum UV tsis muaj VOCs volatiles thiab tsis muaj kuab paug rau huab cua.Cov txheej txheem tsim ntawm UV nplaum tsis tshua muaj kev tiv thaiv lossis txwv tsis pub nyob hauv txhua qhov kev tswj hwm ib puag ncig, thiab tsis muaj qhov hnyav thiab tsis tshua muaj hluav taws kub.Ua raws li kev ruaj ntseg cia thiab kev thauj mus los.
2. Lub curing ceev ntawm UV nplaum yog ceev heev.Siv cov khoom siv UV kho nrog lub zog sib txawv tuaj yeem kho tau tag nrho hauv ob peb feeb mus rau feeb, uas ua rau muaj txiaj ntsig zoo ntawm kev tsim khoom lag luam.Nws yog heev haum rau tsis siv neeg sib dhos kab ntau lawm.Tom qab UV nplaum tau kho, nws tuaj yeem ua tiav qhov kev soj ntsuam kev ua tau zoo ntawm cov nplaum, cov khoom ntim thiab xa khoom xa tuaj, txuag cov khoom hauv pem teb ntawm cov khoom tiav thiab cov khoom tiav.Cov cuab yeej siv hauv cov txheej txheem UV kho feem ntau muaj lub zog qis, uas txuag lub zog muaj txiaj ntsig.Piv nrog rau cov tshav kub curing nplaum, lub zog siv los ntawm kev siv UV curing nplaum tuaj yeem txuag tau 90% ntawm lub zog noj.Tsis tas li ntawd, cov khoom siv kho UV muaj cov qauv yooj yim, thaj chaw me me thiab txuag chaw ua haujlwm.
3. Cov nplaum UV tuaj yeem siv tau yooj yim raws li ntau yam kev mob thiab kev xav tau.Lub sijhawm kho thiab lub sijhawm tos tuaj yeem hloov kho raws li qhov xav tau.Kev kho kom zoo ntawm UV nplaum tuaj yeem hloov kho ntawm qhov xav tau thiab tuaj yeem rov ua dua thiab kho.Nws coj kev yooj yim rau kev tswj hwm ntau lawm.UV curing teeb tuaj yeem yooj yim ntsia ntawm cov kab ntau lawm raws li qhov xwm txheej tiag tiag.Nws tsis xav tau kev hloov kho loj thiab hloov kho.Nws muaj qhov yooj yim uas cov nplaum tsis tuaj yeem sib piv.
2, Qhov tsis zoo ntawm UV nplaum:
1. Tus nqi ntawm cov khoom siv raw rau UV adhesives feem ntau yog siab.Txij li thaum tsis muaj cov kuab tshuaj qis thiab cov khoom ntim hauv cov khoom xyaw, cov nqi tsim khoom ntawm UV adhesives yog siab dua li cov nplaum zoo tib yam, thiab cov nqi muag khoom kuj tseem siab dua.
2. Kev nkag mus ntawm cov hluav taws xob ultraviolet rau qee cov khoom yas lossis cov ntaub ntawv translucent tsis muaj zog, qhov tob curing yog txwv, thiab cov geometry ntawm cov khoom kho tau raug rau qee yam kev txwv.Cov khoom uas tsis tuaj yeem raug irradiated los ntawm ultraviolet rays tsis yog ib qho yooj yim ua kom tiav nyob rau hauv ib lub sij hawm, thiab qhov chaw uas tsis pob tshab yog tsis yooj yim rau kho.
3. zoo tib yam UV nplaum tsuas yog siv tau los khi qee cov khoom siv hluav taws xob.Bonding lub teeb xa khoom siv yuav tsum muaj kev sib xyaw ua ke ntawm lwm txoj kev kho, xws li cationic curing, UV cua sov ob chav kho, UV ya raws ob chav kho, UV anaerobic ob chav kho, thiab lwm yam.
Tag nrho cov khoom ntawm Shenzhen Zicai hom yog dav siv nyob rau hauv ntau yam kev lag luam, xws li ntau yam UV curable coatings, UV curable inks, UV curable adhesives, 3C hluav taws xob khoom, tsheb sab hauv thiab sab nrauv trim qhov chaw, thiab nto hardening thiab hnav-resistant kev kho mob. ntawm ntau yam kev ua yeeb yaj kiab.
