Cov ntaub ntawv kev nyab xeeb: Bis(2,6 - diisopropylphenyl)carbodiimide yog tshuaj lom rau qee yam, thiab yuav tsim cov tshuaj lom neeg thaum nkag mus rau hauv lub cev tsiaj los ntawm kev tswj qhov ncauj, nqus pa lossis txhaj tshuaj intraperitoneal. Piv txwv li, qhov ncauj LD50 ntawm nas yog 200mg / kg, thiab qhov nqus tau LCLo (qis tshaj - concentration lethal koob) yog 100mg / m³ / 6H. Kev ua haujlwm yuav tsum tau ua nyob rau hauv qhov chaw uas muaj qhov cua, thiab cov hnab looj tes tiv thaiv, tsom iav, khaub ncaws tiv thaiv, thiab lwm yam yuav tsum tau hnav kom tsis txhob muaj tawv nqaij thiab nqus tau pa.
Siv
Siv: BIS (2, {6 -}}} Tus neeg sawv cev ua ntej yog tsim los ntawm hydrolysis, tshwj xeeb yog ib qho kev tiv thaiv kev ua kom zoo li Eva, PBT, PLA, TPU. Nws kuj tseem siv tau ua kev ua haujlwm ua kom tiav kom ua tiav cov kev nce qib molecular hnyav ntxiv. Nyob rau tib lub sijhawm, nws tuaj yeem ua raws li cov kua qaub thiab dej scavenger kom tiv thaiv cov roj hmab thiab cov roj kom tiv thaiv cov dej thiab cov roj av ntxeem tau.
