Cov Txheej Txheem Kho UV & EB

Kev kho UV & EB feem ntau piav qhia txog kev siv lub teeb hluav taws xob (EB), ultraviolet (UV) lossis lub teeb pom kev los ua kom muaj kev sib xyaw ua ke ntawm monomers thiab oligomers rau ntawm lub substrate. Cov khoom siv UV & EB yuav raug tsim los ua cov kua mem, txheej, nplaum lossis lwm yam khoom. Cov txheej txheem no kuj hu ua kev kho hluav taws xob lossis radcure vim tias UV thiab EB yog cov khoom siv hluav taws xob. Cov khoom siv hluav taws xob rau UV lossis kev kho lub teeb pom kev feem ntau yog cov teeb mercury nruab nrab, cov teeb xenon pulsed, LEDs lossis lasers. EB - tsis zoo li photons ntawm lub teeb, uas feem ntau raug nqus feem ntau ntawm qhov chaw ntawm cov ntaub ntawv - muaj peev xwm nkag mus rau hauv cov khoom.
Peb Qhov Yog Vim Li Cas Thiaj Yuav Tsum Hloov Mus Siv UV & EB Technology
Kev Txuag Hluav Taws Xob thiab Kev Ua Haujlwm Zoo Dua: Vim tias feem ntau cov tshuab tsis muaj cov kuab tshuaj thiab xav tau tsawg dua ib pliag ntawm kev raug tshuaj, qhov kev nce qib ntawm kev tsim khoom tuaj yeem ua tau zoo heev piv rau cov txheej txheem txheej txheem ib txwm muaj. Kev ceev ntawm kab web ntawm 1,000 ft / min. yog qhov ib txwm muaj thiab cov khoom npaj txhij tam sim ntawd rau kev sim thiab xa khoom.

Haum Rau Cov Khoom Uas Rhiab: Feem ntau cov tshuab tsis muaj dej lossis cov kuab tshuaj. Tsis tas li ntawd, cov txheej txheem no tswj tau tag nrho qhov kub thiab txias ua rau nws zoo tagnrho rau kev siv rau ntawm cov khoom uas rhiab cua sov.

Ib puag ncig thiab Tus Neeg Siv Zoo: Cov khoom sib xyaw feem ntau tsis muaj cov kuab tshuaj yog li cov pa phem thiab kev kub hnyiab tsis yog qhov txhawj xeeb. Cov txheej txheem kho lub teeb sib xws nrog yuav luag txhua txoj kev siv thiab xav tau qhov chaw tsawg kawg nkaus. Cov teeb UV feem ntau tuaj yeem ntsia tau rau ntawm cov kab ntau lawm uas twb muaj lawm.

Cov Khoom Siv Kho Tau UV & EB
Cov monomers yog cov khoom siv yooj yim tshaj plaws uas siv los ua cov khoom siv organic. Ib qho monomer yooj yim uas tau los ntawm cov roj av yog ethylene. Nws yog sawv cev los ntawm: H2C = CH2. Lub cim "=" ntawm ob lub units lossis atoms ntawm carbon sawv cev rau qhov chaw reactive lossis, raws li cov kws tshuaj hu ua, "double bond" lossis unsaturation. Nws yog cov chaw zoo li no uas muaj peev xwm ua rau muaj cov khoom siv tshuaj loj dua lossis loj dua hu ua oligomers thiab polymers.

Ib qho polymer yog ib pawg ntawm ntau (piv txwv li poly-) rov ua dua ntawm tib lub monomer. Lo lus oligomer yog ib lo lus tshwj xeeb siv los txhais cov polymers uas feem ntau tuaj yeem ua rau muaj kev sib xyaw ua ke ntawm cov polymers. Cov chaw tsis muaj zog ntawm oligomers thiab monomers ib leeg yuav tsis dhau los ua kev sib xyaw lossis kev sib txuas.

Yog tias siv lub teeb hluav taws xob kho, cov electrons muaj zog heev cuam tshuam ncaj qha nrog cov atoms ntawm qhov chaw tsis saturated los tsim cov molecule uas muaj zog heev. Yog tias siv UV lossis lub teeb pom kev zoo ua lub zog, tus photoinitiator ntxiv rau hauv qhov sib tov. Tus photoinitiator, thaum raug lub teeb, tsim cov free radical lossis cov haujlwm uas pib sib txuas ntawm cov chaw tsis saturation. cov khoom ntawm UV & ude

Oligomers: Cov khoom ntawm txhua yam txheej, kua mem, nplaum lossis cov ntawv khi uas sib txuas los ntawm lub zog radiant yog txiav txim siab los ntawm cov oligomers siv hauv cov qauv. Oligomers yog cov polymers uas muaj qhov hnyav molecular qis, feem ntau yog raws li acrylation ntawm cov qauv sib txawv. Acrylation ua rau unsaturation lossis "C = C" pawg mus rau qhov kawg ntawm oligomer.

Monomers: Cov Monomers feem ntau yog siv ua cov tshuaj diluents los txo qhov viscosity ntawm cov khoom tsis tau kho kom yooj yim rau kev siv. Lawv tuaj yeem ua monofunctional, muaj tsuas yog ib pawg reactive lossis unsaturation site, lossis multifunctional. Qhov unsaturation no tso cai rau lawv kom react thiab koom ua ke rau hauv cov khoom kho lossis tiav lawm, es tsis txhob volatilizing rau hauv huab cua zoo li feem ntau nrog cov txheej txheem ib txwm muaj. Multifunctional monomers, vim tias lawv muaj ob lossis ntau qhov chaw reactive, tsim kev sib txuas ntawm oligomer molecules thiab lwm yam monomers hauv cov qauv.

Cov Tshuaj Photoinitiators: Cov khoom xyaw no nqus lub teeb thiab yog lub luag haujlwm rau kev tsim cov free radicals lossis kev ua haujlwm. Cov free radicals lossis kev ua haujlwm yog cov hom zog siab uas ua rau muaj kev sib txuas ntawm cov chaw tsis muaj zog ntawm monomers, oligomers thiab polymers. Cov tshuaj Photoinitiators tsis xav tau rau cov txheej txheem kho electron beam vim tias cov electrons muaj peev xwm pib sib txuas.

Cov Khoom Ntxiv: Cov khoom siv feem ntau yog cov khoom ruaj khov, uas tiv thaiv kev sib xyaw ua ke thaum khaws cia thiab kho ua ntej lub sijhawm vim muaj teeb pom kev tsawg. Cov xim pigments, dyes, defoamers, adhesion promoters, flatting agents, wetting agents thiab slip aids yog cov piv txwv ntawm lwm cov khoom ntxiv.
