Daim ntawv thov

1. Ua Dodecenylsuccinic Anhydride ua tus neeg saib xyuas tseem ceeb rau epoxy resins los ua kom muaj kev ua tau zoo - txheej txheej thiab cov nplaum nrog dej zoo heev.

2. Pab DDSA CAS 26544-38-7 ua cov tshuaj tiv thaiv corrosion nruab nrab rau kev tsim cov tshuaj tiv thaiv xeb hauv cov roj lubricating thiab cov kua hlau ua haujlwm.

3. Kev ua haujlwm raws li kev hloov pauv rau polyesters thiab alkyd resins los txhim kho lawv qhov yooj yim thiab kev sib raug zoo nrog ntau yam substrates.

Cia thiab ceev faj

Khaws dodecenylsuccinic anhydride (DDSA, CAS 25377-73-5, daj daj kua nplaum, tsw muaj roj me me, flash point ~ 182 degree, combustible) nyob rau hauv kaw HDPE los yog amber iav ntim ntawm 15-25℃nyob rau hauv ib tug txias, qhuav, zoo-ventilated cheeb tsam. Cais tawm los ntawm cov muaj zog oxidants, acids, bases thiab dej kom tsis txhob hydrolysis thiab decomposition. Hnav hnab looj tes nitrile, looj tsom iav dub thiab lub tsho tiv no; zam vapor inhalation, daim tawv nqaij / qhov muag sib cuag thiab noj kom tsis txhob muaj qhov khaus khaus. Reseal nruj nreem tom qab siv; pov tseg cov pov tseg raws li cov cai hauv zos.

Dab tsi yog qhov txiaj ntsig ntawm kev noj Dodecenylsuccinic Anhydride / DDSA?

Dodecenylsuccinic anhydride yog epoxy curing tus neeg sawv cev thiab tshuaj nruab nrab, tsis yog rau cov ntshiab ntshiab- tsim tib neeg noj; undiluted kev sib cuag yuav ua rau daim tawv nqaij thiab mucosal irritation, thiab noj yuav ua rau gastrointestinal tsis xis nyob.

Hauv cov ntawv thov kev tswj hwm, DDSA CAS 26544-38-7 txhim kho lub zog ntawm cov khoom siv epoxy, txhawb kev tiv thaiv corrosion ntawm lubricants, thiab optimizes cov khoom ua haujlwm ntawm polyester resins.
