Waikawa 1,3,5-Tris(2-hydroxyethyl)cyanuric CAS 839-90-7
Ko te waikawa 1,3,5-Tris(2-hydroxyethyl)cyanuric (Tris 2-hydroxyethyl Isocyanurate), e whakarāpopototia ana ko THEIC, he matū waro nui, me te nama CAS o 839-90-7. He pumau te Tris 2-hydroxyethyl Isocyanurate, ā, kāore e pirau i te pāmahana me te pēhanga noa, engari kāore e hototahi ki ngā waikura kaha. Ko te THEIC he matū heterocyclic kei roto te hauota me te tātai ngota C9H15N3O6. He mea whakamahi noa te Tris 2-hydroxyethyl Isocyanurate i roto i te whakarerekētanga kapia, ngā tāpiri kirihou, ngā paninga me ngā rauemi whakamahana hiko.
Kei roto i te ngota ngota Tris(2-hydroxyethyl) Isocyanurate ngā rōpū hydroxyl, ka taea te tauhohe ki ngā waikawa carboxylic, anhydrides, haloacyl groups, me ētahi atu hei hanga esters. I raro i ngā āhuatanga pāmahana teitei, ka taea e ia te tauhohe ki ngā waikawa dibasic hei hanga hanganga polyester toru-ahu. I raro i ngā āhuatanga pāmahana reo me te iti, ka taea e te THEIC te tauhohe ki te isocyanate hei hanga carbamate, ā, i raro i ngā āhuatanga pāmahana reo me te teitei, ka taea e ia te tauhohe ki te diisocyanate hei hanga polyurethane toru-ahu.

Te mara o ngā rauemi ārai:Ko te Tris 2-hydroxyethyl Isocyanurate te mea e whakamahia nuitia ana mō te hanga i ngā wanihi ārai wera-ātete-wera e ahu mai ana i te polyester. He tino pai te ātete wera (tohu FH), te ātete piko me te ātete ru wera o ēnei wanihi ārai. Ka taea te whakamahi i te Tris(2-hydroxyethyl) Isocyanurate mō te tiakitanga ārai i roto i ngā taputapu whare, ngā koiri motuka iti whānui, me ētahi atu.
I roto i te mara o ngā kirihou:He mea whakaū te Tris(2-hydroxyethyl) Isocyanurate mō te PVC, ka taea te whakanui ake i te pāmahana tukatuka me te mahi a te PVC, ā, ka taea hoki te whakamahi hei hanga i ngā momo kirihou polyurethane.
Ngā mara kē atu:Ka taea te whakamahi i te Tris(2-hydroxyethyl) Isocyanurate hei takawaenga hanga rauropi mō ngā rongoā, ngā patupatu pepeke, ngā tae, me ētahi atu, ā, ka taea hoki te whakamahi i te THEIC ki te hanga peita tunu wairewa-wai, ngā kapia polyester kore mākū, ngā mea whakapūmau kirihou, me ētahi atu.
1.Ahakoa ko te whakaritenga whānui a te umanga mō te parakore he ≥98.0%, ko te paerewa ā-roto o tā mātou umanga he ≥99.0% te tino pakari ake—kia pai ai te ōritetanga me te pono mō āu tono kounga teitei.
