Chaw Tsim Khoom Zoo Nqe P-TOLUENESULFONYLISOCYANATE (PTSI) CAS 4083-64-1

piav qhia luv luv:

P-TOLUENESULFONYLISOCYANATE (PTSI) yog ib qho isocyanate ua haujlwm. P-TOLUENESULFONYLISOCYANATE (PTSI) muaj kev ua haujlwm siab thiab tuaj yeem ua rau cov diisocyanates ib txwm muaj, xws li TDI thiab HDI, nrog dej hauv polyols thiab cov kuab tshuaj. Cov carbamate tshwm sim tsis ua rau lub viscosity ntawm lub kaw lus nce. Qhov tsis zoo yog tias qhov tshuaj lom ntawm oxazolidine thiab lwm yam dehydrants yog loj; P-TOLUENESULFONYLISOCYANATE (PTSI) ua rau cov dej ua pa los tsim cov pa roj carbon dioxide thiab toluenesulfamide, yog li P-TOLUENESULFONYLISOCYANATE (PTSI) tsis tuaj yeem siv ncaj qha rau hauv cov qauv xim thiab feem ntau yog siv rau kev ua kom qhuav ua ntej. Txhawm rau tshem tawm 1g ntawm dej hauv cov kuab tshuaj, kwv yees li 12g ntawm PTSI yog qhov xav tau, tab sis qhov tseeb yuav tsum siab dua qhov no.
