Bis(2,6-diisopropylphenyl) carbodiimideCAS 2162-74-5Ko te monomeric carbodiimide, he momo ātete-waikura e whakaatu ana i ngā āhuatanga o te parakore teitei, te tae mārama, te kore kakara me te kaha nui. E whakamahia whānuitia ana te Bis(2,6-diisopropylphenyl) carbodiimide i roto i ngā rauemi pēnei i te polyester polyol, te nairona, ngā kirihou hangarau kei roto te rōpū ester, ngā elastomers polyurethane, ngā piripiri, ngā pūnaha paninga, me te hinu whakahinuhinu. Ka taea e te Bis(2,6-diisopropylphenyl) carbodiimide te aukati i te waikura o aua rauemi me te whakau i ngā āhuatanga miihini tuatahi. I taua wā anō,bKa taea hoki e te is(2,6-diisopropylphenyl) carbodiimide te aukati i ngā mutunga carboxyl hohe o ngā rauemi polyester. Te whakatika i ngā rauemi polyester me te polyurethane kua pakaru,bKa taea e te is(2,6-diisopropylphenyl) carbodiimide te whakaroa i te roa o te ora o ngā hua polymer i raro i ngā āhuatanga mahi uaua pēnei i te pāmahana teitei me te haumākū..

I roto i te mara o te pūtaiao rauemi, bis(2,6-diisopropylphenyl)carbodiimide, hei whakaū ārai-waipiro carbodiimide monomeric, kua noho hei arotahi mā te umanga nā te mea he pai rawa te mahi me ngā tūmanakohanga whānui mō te tono.

Tuatahi,E whakamahia whānuitia ana te bis(2,6-diisopropylphenyl) carbodiimide i roto i ngā elastomers polyurethane (pēnei i te TPU, te CPU), ngā piripiri, ngā otinga sole me ngā elastomers Microporous, me ētahi atu. I roto i ēnei mara, mā te tāpiri i te 0.3-2.0% bis(2,6-diisopropylphenyl)carbodiimide, ka taea te whakapai ake i te roa o te ora o te hua, ka roa ake i te 1 ki te 3 ngā wā.

Tuarua, i te wā o te tukanga whakarerekētanga o ngā rauemi polyester pēnei i te PET/PBT, mā te tāpiri i te bis(2,6-diisopropylphenyl) carbodiimide ka taea te whakaiti i te uara waikawa o te polyester. Ka taea te whakatutuki i ngā whakapainga nui o te kounga o te rauemi mā te iti o ngā rahinga tāpiri, ka roa ake te pumau o te rauemi mō te wā roa.

Haunga te whakamahinga hei āpiha ārai-waikura, ka taea hoki te whakamahi i te bis(2,6-diisopropylphenyl)carbodiimide hei āwhina tukatuka hei tauhohe ki ngā waikawa carboxylic i puta i te wā o te tukanga extrusion. Ka ārai i te whakahekenga o te taumaha ngota, ka ngoikore te kino ki te polymer i te wā e tukatuka ana, ka māmā ake te whakahaere me te whakapai ake i te haumaru tukatuka ki te whakataurite ki ētahi atu tikanga.

Hei tāpiritanga, mō te PLA kirihou pirau-taiao, he pai mō te taiao, ko te ātete ngoikore ki te wai te take nui e aukati ana i tōna whakamahinga whānui. Ka ngawari te pirau o te PLA i roto i ngā taiao makuku, ka pā ki tōna mahi me tōna roanga o te ora. Heoi, mā te tāpiri i te 0.3-0.5% bis(2,6-diisopropylphenyl)carbodiimide ki te PLA, ka taea te whakapai ake i tōna ātete wai mā te 3-7 ngā wā, ka whānui ake tetngā mara tono o te PLA.

Hei whakarāpopototangamKo te ary, bis(2,6-diisopropylphenyl)carbodiimide, hei whakaū ā-teitei mō te ārai-wai, kua whakaatu i te kaha whānui me te pūmanawa ki te whakamahi i roto i te ao o te pūtaiao rauemi.ItNā te tino pai o ngā āhuatanga ā-tinana me te matū o tēnei rauemi, te whānuitanga o ngā tono, me ngā otinga kua tohua mō ngā rauemi motuhake (pēnei i te PLA) ka waiho te bis(2,6-diisopropylphenyl)carbodiimide hei kaiārahi i roto i te whakaū rauemi. I te haere tonu o te whanaketanga o te pūtaiao rauemi me te piki haere o te mōhiotanga ki te tiaki taiao, e tūmanakohia ana ka whakatairangahia, ka whakamahia hoki te bis(2,6-diisopropylphenyl)carbodiimide me ōna hua rite ki roto i ngā mara maha atu.
