Utu Pai a te Kaihanga D230 CAS: 9046-10-0

whakaahuatanga poto:

He wai mārama te D230, he wai mārama kōwhai mārama, he wai kore tae rānei te D230 i te pāmahana rūma. He iti te matotoru o te D230, he iti te pēhanga kohu, ā, he nui te ihirangi amine tuatahi. Ka taea te rewa te D230 ki roto i te etanoru, ngā hauwaiwaro aliphatic, ngā hauwaiwaro kakara, ngā ester, ngā etera glycol, ngā ketone me te wai.

Ngā Āhuatanga Matū: Ko te Poly(propylene glycol) bis(2-aminopropyl ether) he wai mārama, he kowhai mārama, he kore tae rānei i te pāmahana rūma, he iti te matotoru, he iti te pēhanga kohu, he nui te ihirangi amine tuatahi, ā, ka wairewa i roto i ngā whakarewa pērā i te etanoru, ngā hauwaiwaro aliphatic, ngā hauwaiwaro kakara, ngā ester, ngā ether glycol, ngā ketone me te wai.

Ngā tono o D230

Ko te nuinga o te wā ka whakamahia mō te rehu i te elastomer polyurea, ngā hua awhi, te kaihoko whakaora kapia epoxy, me ētahi atu. Ko te elastomer polyurea rehu i hangaia mai i te polyether amino terminated me te isocyanate he kaha teitei, he roa te roa, he ātete ki te waku, he ātete ki te waikura me te ātete ki te koroheketanga. He whānuitia te whakamahinga i roto i ngā paninga ā-wai, ā-waikura me te ātete-kakahu i runga i ngā mata o ngā hanganga raima me te maitai, tae atu ki ngā paninga tiaki me ngā paninga whakapaipai i runga i ētahi atu wāhanga. Ko te polyether amino terminated e whakamahia ana i roto i te kaihoko whakaora kapia epoxy ka taea te whakapai ake i te pakari o ngā hua, ā, he whānuitia te whakamahinga i roto i te hanga mahi toi kapia epoxy.
Te Whakarite: te Hanganga o te Poly(propylene glycol) bis(2-aminopropyl ether): Tuatahi, ka piri te polyether ki te rōpū acetoacetate i ngā pito e rua mā te dienone, mā te tauhohenga whakawhiti ester rānei o te ethyl acetoacetate me te polyol polyether, kātahi ka whakananua te polyether kua taupokina e te rōpū acetoacetate ki te amine mono-primary, te amine alcohol alkyl, te amine tuatahi dibasic rānei hei whiwhi i tētahi matū imine he iti te matotoru me te rōpū mutunga aminobutyrate.
