Xim tuaj yeem pom txhua qhov chaw hauv peb lub neej, thiab peb tsis paub txog nws.Tej zaum rau cov coatings kawm hauv lub neej, lawv yog cov hnyav dua los yog thermosetting.Txawm li cas los xij, kev txhim kho tam sim no yog UV xim, uas yog xim ntsuab xim ntsuab.
UV pleev xim, lub npe hu ua "tshiab thiab ib puag ncig tus phooj ywg ntsuab xim nyob rau hauv lub xyoo pua 21st", tab tom tsim ntawm tus nqi ntawm ntau tshaj ob zaug ntawm kev noj txhua xyoo.Qhov tshwm sim ntawm UV xim yuav ua rau lub ntiaj teb hloov pauv hauv daim ntawv thov qauv ntawm cov txheej txheem ib txwm muaj.UV xim yog dab tsi?Qhov kev cuam tshuam deb npaum li cas yuav nws qhov tshwm sim muaj nyob rau hauv kev lag luam rooj tog tsim khoom?
UV xim yog dab tsi?
UV pleev xim yog hais txog ultra violet curing xim, uas yog, txheej txheej uas siv UV ua lub zog kho thiab nrawm nrawm ntawm chav tsev kub.Lub teeb ultraviolet yog tsim los ntawm cov cuab yeej tshwj xeeb, thiab cov txheej txheem uas cov khoom irradiated tsim cov tshuaj tiv thaiv los ntawm UV lub teeb hluav taws xob thiab kev hloov ntawm cov kua rau cov khoom yog hu ua UV curing txheej txheem.
UV kho tshuab yog lub zog txuag, huv si thiab ib puag ncig-phooj ywg technology.Nws txuag lub zog - nws lub zog siv tsuas yog ib feem tsib ntawm thermal curing.Nws tsis muaj cov kuab tshuaj, muaj kuab paug me me rau thaj chaw ecological, thiab yuav tsis tawm cov pa phem thiab carbon dioxide rau hauv qhov chaw.Nws yog lub npe hu ua "green technology".UV kho tshuab yog ib hom kev siv tshuab thev naus laus zis uas ua rau cov kua epoxy acrylic resin polymerized rau hauv lub xeev ruaj khov ntawm kev kub ceev los ntawm UV irradiation nrog qee qhov wavelength.Diam duab kho cov tshuaj tiv thaiv yog qhov tseem ceeb ntawm daim duab pib polymerization thiab kev sib txuas sib txuas.UV curable coatings tau txais kev pom zoo los ntawm kev lag luam txheej vim tias lawv cov txheej txheem ua haujlwm zoo thiab cov yam ntxwv zoo ib puag ncig.
Koj paub ntau npaum li cas txog UV xim?Xyoo 1968, Bayer tau ua tus thawj coj hauv kev siv UV curing system ntawm unsaturated resin thiab benzoic acid los tsim cov khoom lag luam, thiab tsim thawj tiam ntawm UV curing coatings.Thaum xyoo 1970s, Sun Chemical Company thiab immontconciso lub tuam txhab tsim UV curable number case successively.
Thaum xyoo 1980s, Taiwan cov chaw tsim khoom hauv pem teb tau pib nqis peev thiab tsim cov chaw tsim khoom hauv thaj av loj, thiab uvpaint daim ntawv thov thiab cov thev naus laus zis ntau lawm kuj tau qhia.Ua ntej nruab nrab-1990s, uvcoatings feem ntau yog siv rau xyoob thiab ntoo hauv pem teb ua thiab yas npog polishing, thiab feem ntau yog pob tshab.
Nyob rau hauv xyoo tas los no, nrog kev ua haujlwm loj ntawm cov rooj tog zaum hauv tsev, uvpaint tau maj mam nkag mus rau hauv cov txheej txheem ntoo, thiab nws cov txiaj ntsig tau pom dav dav.Tam sim no, uvpaint tau siv dav hauv ntawv, yas, hlau, iav, ceramics thiab lwm yam, thiab tab tom txhim kho nyob rau hauv cov kev taw qhia ntawm functionalization.
Kev lag luam zeem muag ntawm UV txheej
UV pleev xim, koj puas paub ntau npaum li cas ntawm cov tsoos coatings siv hauv kev lag luam rooj tog zaum tam sim no tseem yog Pu, PE thiab NC.Los ntawm kev siv tshuaj tsuag, qhov ua tau zoo yog qhov tsawg, thiab nws nyuaj rau kev nrhiav neeg ua haujlwm thiab tus nqi ua haujlwm siab.Tsuas yog los ntawm kev txhim kho qib ntawm kev tsim khoom automation ntawm cov rooj tog tsim khoom lag luam tuaj yeem ua rau lawv tawg lub bottleneck ntawm txoj kev loj hlob thiab txhim kho kev lag luam efficiency.Ntawm qhov tod tes, VOC tso tawm los ntawm cov chaw tsim khoom rooj tog siv cov txheej txheem ib txwm ua tau dhau los ua qhov tseem ceeb ntawm kev ua qias tuaj ib puag ncig.Tam sim no, qis-carbon kev lag luam thiab kev noj zaub ntsuab tau nrov, uas yuav ua rau muaj kev tsim cov qauv tshiab thiab kev cuam tshuam kev lag luam.Cov teb chaws tsim kho xws li Tebchaws Europe thiab Tebchaws Meskas tau tsim thiab tshaj tawm ntau txoj cai tswjfwm los txhawb kev lag luam rooj tog kom tsim kho ntsuab thiab kev tiv thaiv ib puag ncig.Cov tuam txhab tsim rooj tog hauv tsev, tshwj xeeb tshaj yog cov lag luam xa tawm, tab tom ntsib cov kev sib tw ua ntej.
Nyob rau hauv keeb kwm yav dhau ntawm txoj kev loj hlob ntawm kev lag luam, uvcoatings ua raws li cov qauv ntawm lub sij hawm thiab dhau los ua ib tug tshiab tiam ntawm txoj kev loj hlob ntawm rooj tog txheej.Nws cov txiaj ntsig zoo li ib puag ncig-phooj ywg thiab txuag hluav taws xob thiab emission txo txheej yog maj mam tshwm sim, uas kuj tau txais kev nyiam ntawm cov koom haum hauv tebchaws.Lub 11th Tsib Xyoo Plan rau kev txhim kho cov txheej txheem kev lag luam thiab cov phiaj xwm kev loj hlob nruab nrab thiab ntev rau kev tshawb fawb thiab thev naus laus zis ntawm txheej txheej kev lag luam kom meej meej tso rau pem hauv ntej qhov yuav tsum tau ua kom muaj zog tiv thaiv ib puag ncig UV txheej.UV xim tab tom yuav tawm thawj zaug hauv kev lag luam, thiab kev lag luam zeem muag yog qhov ntsuas tsis tau.
