Cia thiab ceev faj
Khaws UV - 329 (CAS 3147-75-9, dawb crystalline hmoov, tsis muaj ntxhiab, mp 103-106 degree, purity Ntau dua lossis sib npaug li 99%, tsis yog-flammable) ntawm 10-25℃hauv ntim amber iav / HDPE ntim rau hauv qhov chaw txias, qhuav, tsaus thiab zoo. Cais tawm los ntawm cov muaj zog oxidants, acids thiab ncaj qha tshav ntuj kom tsis txhob oxidation thiab photodegradation. Hnav hnab looj tes nitrile, looj tsom iav dub thiab plua plav npog; zam plua plav nqus, tawv nqaij/qhov muag thiab noj kom tsis txhob mob me me. Reseal nruj nreem tom qab siv; pov tseg cov pov tseg ib cheeb tsam UV absorber ib puag ncig cov cai.
Dab tsi yog qhov txiaj ntsig ntawm kev noj UV-329 / UV ABSORBER 329?
UV - 329 yog ib qho kev lag luam polymer UV absorber, tsis yog rau ncaj qha ntshiab - daim ntawv rau tib neeg kev sib cuag lossis noj; undiluted sib cuag tej zaum yuav ua rau me ntsis ntawm daim tawv nqaij dryness, thiab kev huam yuaj yuav ua rau gastrointestinal tsis xis nyob. Hauv cov ntawv thov kev tswj hwm, nws muaj zog UV nqus (300-}400nm) thiab pom lub teeb pom kev tsawg, zoo thermal stability rau siab - kub ua, zoo compatibility nrog ntau yam polymers, thiab synergizes zoo nrog HALS / antioxidants los txhawb lub sij hawm ntev huab cua tsis kam.
