Soo saaraha Qiimaha Wanaagsan P-TOLUENESULFONYLISOCYANATE (PTSI) CAS 4083-64-1

sharaxaad gaaban:

P-TOLUENESULFONYLISOCYANATE (PTSI) waa isocyanate keli ah oo shaqaynaysa. P-TOLUENESULFONYLISOCYANATE (PTSI) waxay leedahay firfircooni sare waxayna la falgali kartaa diisocyanates caadiga ah, sida TDI iyo HDI, oo leh biyo ku jira polyols iyo dareerayaasha. Carbamate-ka soo baxa ma kordhinayo viscosity ee nidaamka. Khasaaraha ayaa ah in sunta oxazolidine iyo fuuq-baxayaasha kale ay weyn yihiin; P-TOLUENESULFONYLISOCYANATE (PTSI) waxay la falgashaa biyaha si ay u soo saarto kaarboon laba ogsaydh iyo toluenesulfamide, markaa P-TOLUENESULFONYLISOCYANATE (PTSI) si toos ah looguma isticmaali karo qaababka rinjiga waxaana guud ahaan loo isticmaalaa fuuq-bax ka hor. Si loo soo saaro 1g oo biyo ah dareeraha, qiyaastii 12g oo PTSI ah ayaa aragti ahaan loo baahan yahay, laakiin qaddarka dhabta ahi waa inuu ka sarreeyaa tan.
