Ngā tono

He momo matū nui ngā diamine e whakamahia whānuitia ana hei rauemi mata, hei takawaenga, hei hua rānei. Hei tauira, he wāhanga hanganga nui ngā diamine i roto i te hanganga o te polyamide me ētahi atu tauhohenga polymerization condensation. He takawaenga nui te N,N-dimethyl-Chemicalbook1,3-diaminopropane (DMAPA), e whakamahia ana hei tauira i roto i te whakaritenga ahumahi o ngā hinu whakahinuhinu. Hei tāpiri, ka whakamahia te DMAPA hei rauemi mata mō te whakarite i ngā coagulants, ā, me whai āhuatanga ārai-waikura anō hoki.
