Cov tshuaj ntxiv yog siv los txhim kho kev ua tau zoo ntawm tus cwj mem. Additives feem ntau siv hauv UV number case suav nrog tus stabilizer, tus neeg sawv cev qib, defoamer, dispersant, siv quav ciab, thiab lwm yam.
(1) Stabilizer: stabilizer yog siv los txo cov thermal polymerization thaum khaws cia thiab txhim kho kev khaws cia ruaj khov ntawm tus lej. Hydroquinone, p-methoxyphenol, p-benzoquinone thiab 2,6-di-t-butyl cresol feem ntau siv.
(2) Tus neeg saib xyuas qib: tus neeg saib xyuas qib tau siv los txhim kho qib qib ntawm tus lej, tiv thaiv kev ntsws, ua rau cov kua nplaum zaj duab xis tiaj tus, thiab nce qhov ci ntawm number case luam ntawv.
(3) Defoamer: defoamer tau siv los txhim kho qib qib ntawm tus lej number case, tiv thaiv kev tsim cov ntsws, ua kom du ntawm cov kua nplaum zaj duab xis, thiab nce qhov ci ntawm cov ntawv luam ntawv.
(4) Dispersant: dispersant tuaj yeem ua rau cov xim nyob rau hauv tus number case zoo thiab qis ntub hauv cov phau ntawv, ua kom cov xim tawg zoo nyob hauv tus lej, thiab ua kom luv lub sij hawm sib tsoo thaum tsim cov xim; Txo cov roj nqus dej ntawm cov xim kom tsim cov xim siab ntau; Tiv thaiv kev sib sau ua ke thiab nag lossis daus ntawm cov xim nyob hauv tus lej. Dispersants feem ntau yog surfactants.
(5) Ciab: lub luag haujlwm tseem ceeb ntawm siv quav ciab yog hloov qhov rheology ntawm tus lej, txhim kho dej tsis kam thiab luam ntawv ua haujlwm (xws li kho cov viscosity), txo qhov tsis zoo xws li av thiab ntawv ntaub plaub, tsim cov nplaum zaj duab xis du ntawm qhov chaw zaj duab xis ziab qhuav, thiab txhim kho qhov hnav tsis kam ntawm cov ntawv luam tawm. Hauv UV number case, siv quav ciab kuj thaiv huab cua, txo cov pa oxygen polymerization, thiab muaj txiaj ntsig zoo rau kev kho saum npoo. Txawm li cas los xij, ntxiv cov ciab ntau dhau thiab xaiv cov ciab tsis raug hauv tus number case yuav txo qhov ci ntawm tus number case, rhuav tshem tus lej hloov pauv kev ua haujlwm thiab ua kom lub sijhawm ziab kom qhuav.
