He aha te 4,4'-Azobis(4-cyano-1-pentanol) CAS 4693-47-4?

He totoka mā ki te mā-parauri te 4,4'-Azobis (waikawa 4-cyanovaleric) i te pāmahana rūma me te pēhanga. He nui te waikawa, ā, he iti te pumau o te matū. Kāore e tino wairewa ki te wai engari ka wairewa ki ngā whakarewa waro waipiro. Ko te 4,4'-azobis (waikawa 4-cyanovaleric) he matū whakaoho pūmua e tairongo ana ki te mārama kaha, ā, ka taea te whakamahi i roto i te hanga polyvinyl chloride, polyacrylonitrile, Te hanga me te whakarite i ngā pūmua pēnei i te waipiro vinyl me ngā muka whatu hangai.

1. Te whakamahinga i roto i ngā tauhohenga polymerization

Ko te 4,4'-azobis(4-cyanopentanol) he matū azo ka taea te whakamahi hei whakaoho mō ngā tauhohenga polymerization. I roto i te tukanga polymerization radical free, ka taea e ia te pakaru hei whakaputa i ngā radical free hei tīmata i te polymerization monomer. Hei tauira, i roto i te tauhohenga polymerization o ngā monomer vinyl pērā i te acrylates me te styrenes, ka taea e ia te whakahaere pai i te tīmatanga me te tere o te tauhohenga polymerization. Ka taea e ngā radical free i puta mai i tōna pakaru te tīmata i te whakatuwheratanga o ngā hononga takirua i roto i ngā ngota monomer, kātahi ka hono tetahi ki tetahi hei hanga mekameka polymer.

He painga anō tō tēnei kaiwhakaoho, pērā i te whakarato i te tere whakaputa rauropi kore utu pumau i raro i ngā āhuatanga pāmahana e tika ana, kia pai ai te haere o te tauhohenga polymerization, e whai hua ana mō te hanganga o ngā polymer me te tohatoha taumaha ngota whaiti.

2. Te tūranga i roto i te whakarite i ngā rauemi pahuka

Ka taea hoki te whakamahi hei whakarite i ngā rauemi pahuka. I roto i te whakarite i ngā rauemi pahuka pēnei i te polyurethane, ka taea e te 4,4'-azobis(4-cyanopentanol) te whai wāhi ki te tauhohenga hei whakaputa hau, ā, ka whai wāhi hoki ngā rauropi kore utu me ētahi atu rōpū hohe i puta mai i tōna pirau ki te hononga whakawhiti me te whakamaroke i ngā matrices polymer pēnei i te polyurethane. Mā tēnei pānga takirua ka taea e te rauemi pahuka te hanga i tētahi hanganga pūwero ōrite, ā, ka taea te whakahaere i te rahi me te tohatoha o ngā pūwero mā te whakarerekē i ngā āhuatanga pēnei i tō rātou horopeta, kia pai ake ai ngā āhuatanga ā-tinana o te rauemi pahuka, pēnei i te whakaiti i te kiato o te rauemi, te whakapai ake i te ngāwari me ngā āhuatanga whakangāwari o te rauemi, me ētahi atu.
