TPU yuav nqus dej noo hauv huab cua thiab ua dawb hauv huab cua lossis nws yog kev tsiv teb tsaws ntawm cov khoom siv ntxiv thaum ua, feem ntau vim tias tus neeg sawv cev plam yog opaque, thiab yellowing yog tus yam ntxwv ntawm TPU.
TPU yog xim daj. Hauv ISO, MDI yuav tig daj nyob rau hauv ultraviolet lub teeb. Nws tuaj yeem pom tias TPU yellowing yog tus cwj pwm, yog li peb yuav tsum ncua lub sijhawm daj ntawm TPU. Yog li yuav ua li cas tiv thaiv TPU los ntawm yellowing? Muaj ntau ntau yam, tab sis qhov chaw yuav tsum tau ntxoov ntxoo.
1. Tsis txhob raug tshav ntuj rau TPU. TPU cia qhov chaw yuav tsum txias thiab qhov cua, thiab TPU tuaj yeem muab ntim rau hauv hnab yas thiab muab tso rau hauv qhov chaw tsis muaj hnub ci.
2. Txau cov xim daj-resistant. Feem ntau muaj ob hom tshuaj pleev xim, ib qho yog txau rau hauv pwm thiab lwm yam yog txau sab nraum pwm. Kev txau cov xim daj-tiv taus yuav tsim cov txheej txheem tiv thaiv ntawm TPU cov khoom tiav los tiv thaiv cov tawv nqaij PU los ntawm kev tiv thaiv huab cua. Cov pa phem yellowing, daim ntawv no tau siv dav.
3. Ntxiv cov tshuaj tiv thaiv daj. Txhawm rau ntxiv dag zog rau kev tiv thaiv daj muaj peev xwm ntawm TPU cov khoom lag luam, feem ntau yuav tsum tau ntxiv ib tus neeg sawv cev tshwj xeeb los tiv thaiv daj rau cov khoom siv raw, tab sis tus neeg saib xyuas daj yog kim, thiab peb kuj yuav tsum ntsuas nws cov txiaj ntsig kev lag luam thaum siv tshuaj tiv thaiv. -yellowing agents, xws li peb cov dub Lub cev tsis rhiab rau yellowing, yog li peb tuaj yeem siv pheej yig dua cov khoom siv tsis-daj tsis ntxiv cov tshuaj tiv thaiv daj. Txij li thaum tus neeg sawv cev tiv thaiv daj yog cov khoom siv raw khoom ntxiv, nws ntxiv rau cov khoom A. Peb yuav tsum tau nplawm thaum sib tov Txhawm rau faib tusyees thiab ua tiav cov nyhuv los tiv thaiv daj, txwv tsis pub lub zos yellowing yuav tshwm sim.
4. Siv qhov sib tov zoo. Ib qho piv txwv zoo tuaj yeem ua rau I kua thiab P kua ua tiav qhov kev sib xyaw ua ke uas tsis muaj kev xav tsis tiav. Thaum cov phenomena tshwm sim, cov khoom tiav yuav tiv taus hydrolysis thiab txo qhov muaj peev xwm los tiv thaiv daj, tshwj xeeb tshaj yog thaum qhov sib piv siab dhau. Yuav ua kom lub yellowing ntawm cov khoom tiav.
5. Tsis txhob muaj kuab paug thaum lub sijhawm ua haujlwm. Ntau cov khoom TPU raug paug thaum lub sijhawm ua tiav lossis khaws cia, ua rau yellowing xws li tib neeg hws thiab cov kuab tshuaj organic. Yog li ntawd, cov khoom siv TPU yuav tsum tau them nyiaj tshwj xeeb rau kev huv ntawm lub cev tiv tauj thiab txo cov txheej txheem tiav kom ntau li ntau tau.
