ETIRENE KIRIKORO BIS (4-TRIMELLITATE ANHYDRIDE) CAS:1732-96-3

"Ko te Ethylene Glycol Bis (4-trimellitate anhydride), e mōhiotia whānuitia ana ko EGTMAC, he matū maha-mahi me ngā tono kanorau puta noa i ngā ahumahi rerekē. Ko tētahi o ōna whakamahinga matua kei roto i te mara o te pūtaiao polymer. Ko te EGTMAC he kaihoko hononga me te monomer nui i roto i te hanga polymer me ngā kapia mahi-teitei. Ka whakaatuhia e ēnei polymer te pumau wera tino pai, te kaha miihini, me te ātete ki ngā matū me ngā whakarewa. Ko te whakaurunga o te EGTMAC ka whakarei ake i te mahi me te roa o ngā matrices polymer hua, ka pai ai mō ngā tono i roto i ngā paninga, ngā piripiri, me ngā rauemi hiato. Hei tāpiri, he mahi nui tā te EGTMAC i roto i te matū rauemi. Mā ōna rōpū anhydride ka taea e ia te tauhohe ki ngā momo matū, ka arahi ki te hanganga o ngā rauemi mahi pēnei i ngā kapia thermosetting, ngā tāpiringa aukati-mumura, me ngā paninga ātete-mumura. Ka kitea e ēnei rauemi ngā tono i roto i ngā ahumahi e hiahia ana ki te pumau pāmahana-teitei, te aukati-mumura, me te ātete ki te waikura, tae atu ki ngā rāngai rererangi, motuka, me te hanga. Hei tāpiri, he whānui te whakamahinga o te EGTMAC i roto i te hanga rauropi. Mā tōna tauhohenga ka taea te mahi o ngā pūmua, ngā oligomer, me ngā ngota iti, e ārahi ana ki te whanaketanga o ngā matū motuhake, ngā plasticizer, me ngā tāpiringa hinu. Ka whakamahia e ngā kairangahau te EGTMAC hei takawaenga matua ki te hanga i ngā pūhui waro matatini me ngā āhuatanga kua whakaritea mō ngā tono ahumahi me ngā tono arumoni motuhake. Heoi anō, ka kitea te whai huatanga o tēnei pūhui i roto i te mara o te whakarerekētanga mata me te whakatairanga piri. Nā tōna kaha ki te hanga hononga covalent pakari me ngā momo papa rerekē ka pai mō te whakarerekē i ngā mata me te whakarei ake i te piri i waenga i ngā rauemi rerekē. Ka whakamahia ngā kaiwhakatairanga piri e hangai ana ki te EGTMAC i roto i ngā paninga, waituhi, me ngā piripiri hei whakapai ake i te kaha piri me te pumau mo te wa roa. Hei whakarāpopototanga, he nui ngā tono a te Ethylene Glycol Bis (4-trimellitate anhydride), te EGTMAC rānei, i roto i te pūtaiao pūmua, te matū rauemi, te hanga waro, me te whakarerekētanga mata. Nā tōna hanganga anhydride ahurei me te tauhohenga maha-whakamahinga ka waiho hei pūhui whai hua mō te whakawhanake i ngā pūmua mahi-teitei, ngā rauemi mahi, ngā ngota waro matatini, me ngā kaiwhakatairanga piri. Nā te whānuitanga o ngā tono ka waiho te EGTMAC hei wāhanga nui ki te whakatairanga i ngā whanaketanga hangarau me te rangahau pūtaiao.
