Auxiliaries yog cov koom haum pab cuam ntawm UV txheej.Lub luag haujlwm ntawm cov khoom siv ntxiv yog txhawm rau txhim kho cov txheej txheem kev ua haujlwm, kev ua haujlwm cia thiab kev tsim kho, txhim kho cov yeeb yaj kiab ua haujlwm thiab muab qee qhov tshwj xeeb ua haujlwm.UV coatings feem ntau siv additives yog defoaming tus neeg saib xyuas, leveling tus neeg saib xyuas, wetting dispersant, adhesion promoter, extinction agent, polymerization inhibitor, thiab lwm yam, lawv ua lub luag haujlwm sib txawv hauv UV txheej.
(1) Qhov sib ntxiv ntawm tus neeg saib xyuas antifoaming thiab tus neeg sawv cev antifoaming tuaj yeem zam kev tsim cov dej ntws, thaum ntxiv cov tshuaj tiv thaiv kab mob tuaj yeem tshem tawm cov ua npuas ncauj.Vim tias cov sawv cev ntawm defoaming yog tsawg, tshwj xeeb tshaj yog kom daws cov ua npuas dej tsis zoo, yog li qhov ntau ntxiv, yooj yim kom ua rau muaj qhov txhab.Nyob rau hauv xyoo tas los no tshwm sim cov defoaming tus neeg sawv cev uas muaj fluorine dua, defoaming nyhuv yog zoo, ntau npaum li cas tsawg heev.
(2) Tom qab kev tsim kho ntawm cov txheej txheem txheej txheej txheej txheej, muaj cov txheej txheem ntws thiab qhuav zaj duab xis.Qhov degree uas cov zaj duab xis ntub dej tuaj yeem ntws thiab tshem tawm cov cim tom qab thov, thiab cov yeeb yaj kiab tuaj yeem ua tau txawm tias thiab tiaj tus tom qab ziab, hu ua leveling.
(3) wetting dispersant wetting tus neeg saib xyuas, dispersant yog txhawm rau txhim kho kev ua haujlwm ntawm cov xim sib tsoo, kom muaj kev ruaj ntseg ntawm qhov system dispersion tsim nyog rau chav kawm ntawm cov khoom ntxiv.Wetting tus neeg saib xyuas thiab dispersant muaj qhov nro qis thiab zoo compatibility nrog resin system.Cov wetting dispersants siv nyob rau hauv UV txheej yog tsuas yog polymers uas muaj pigments thiab pab pawg.
(4) adhesion promoter adhesion promoter yog ib hom additive tuaj yeem txhim kho qhov adhesion ntawm txheej thiab substrate, rau qee cov txheej yog nyuaj rau ua raws li cov substrate xws li hlau, yas, iav, thiab lwm yam., nyob rau hauv txheej feem ntau ntxiv tib neeg. adhesion txhawb.
(5) lub gloss ntawm extinction agent yog ib qho tseem ceeb ntawm cov txheej txheem tom qab tsim zaj duab xis.Txhawm rau ua kom tsis muaj gloss lossis matt txheej, nws yog ib qho tsim nyog yuav tsum ntxiv tus neeg sawv cev rau hauv txheej kom ua tiav.Extinction agent refractive index kom ze li sai tau rau qhov refractive index ntawm resin (1.40 ~ 1.60), kom cov kev npaj ntawm extinction txheej transparency yog zoo, kuj tsis cuam tshuam rau cov xim ntawm cov xim.
(6) polymer inhibitor qhov no yog siv rau UV txheej hauv kev tsim khoom, kev thauj mus los thiab kev cia kom tsis txhob thermal polymerization, txhim kho kev ruaj ntseg ntawm UV txheej thiab ntxiv cov khoom ntxiv.Lawv yuav tsum nyob rau hauv lub xub ntiag ntawm oxygen los tsim polymerization tsis kam, yog li UV txheej cia ntim, yuav tsum tau muab tso tseg kom txaus cua kom ntseeg tau tias muaj oxygen txaus.
