Cov ntawv thov

Diamines yog ib hom tshuaj tseem ceeb uas siv dav ua cov khoom siv raw, cov khoom nruab nrab lossis cov khoom lag luam. Piv txwv li, diamines yog cov khoom tseem ceeb hauv kev tsim cov polyamide thiab lwm yam kev sib xyaw ua ke polymerization. N,N-dimethyl-Chemicalbook1,3-diaminopropane (DMAPA) yog ib qho khoom nruab nrab tseem ceeb, siv piv txwv li hauv kev npaj cov roj nplua nyeem hauv kev lag luam. Tsis tas li ntawd, DMAPA yog siv ua cov khoom siv raw rau kev npaj cov coagulants thiab nws tus kheej yuav tsum muaj cov khoom tiv thaiv xeb.
