I roto i te ao pūtaiao rauemi e whanake tonu ana, ko te polyurethane tonu te pou tūāpapa nā te mea he maha ngā whakamahinga mai i ngā pahuka ngohengohe ki ngā hanganga pakari me ngā mara CASE (Coatings, Adhesives, Sealants, and Elastomers). Hei kaiwhakarato matua ongā whakakorikori polyurethane, e whakahīhī ana mātou ki te whakauru i a Catalyst MB20, he whakakorikori waro kei roto i te bismuth, i hangaia hei whakarei ake i te mahi me te whai huatanga o ngā pūnaha polyurethane.
Kaikōkiri MB20Te Hanganga me te Tikanga
Ko te Catalyst MB20 he catalyst bismuth waro hou e tū motuhake ana nā tōna kaha ahurei ki te whakahaere i ngā tauhohenga polyurethane. Ko te Bismuth, hei huānga, he huarahi pai hei whakakapi i ngā catalysts konganuku taumaha tuku iho nā te mea he iti ake te paitini me te pānga ki te taiao. Ko te mahi catalyst o te MB20 nā ngā pokapū bismuth e taunekeneke ana me ngā rōpū isocyanate i roto i ngā hanganga polyurethane, e whakateretere ana i te tauhohenga me ngā polyol hei hanga i ngā hanganga polymer e hiahiatia ana.
Ngā tono i roto i ngā pahuka polyurethane ngohengohe me ngā pahuka polyurethane mārō
He whānuitia ngā pahuka polyurethane ngohengohe i roto i ngā mahi pēnei i te urunga o ngā taonga, ngā nohoanga motuka, me ngā moenga. He mea nui te ngāwari me te pakari o ēnei pahuka, ā, he mea nui te mahi a te MB20 ki te whakapai ake i ēnei āhuatanga. Ina whakamahia hei whakakorikori, ka whakarei ake te MB20 i te tere tauhohenga, ka whakarite kia ōrite te hanganga pūtau me te kiato ōrite i roto i te pahuka. Ko te hua o tēnei he hua e tutuki ana i ngā paerewa ahumahi mō te whakamarie me te roa, engari e hipa ana hoki.
I tetahi atu taha, he mea nui ngā pahuka polyurethane mārō mō te hanga whare mō ngā kaupapa whakamahana, nā te mea he pai rawa atu ō rātou āhuatanga whakamahana. Mā te whai huatanga o te MB20 ka tere te whakatutuki a ēnei pahuka i te pakari me te kaha e hiahiatia ana, he mea nui tēnei mō ngā tono e tino hiahiatia ana te pumau o ngā āhuatanga me te ātete wera. Mā te tere o te whakamaroke e āwhinahia ana e te MB20 ka whakapotohia hoki ngā huringa whakaputa, ka whakarei ake i te whai huatanga o te whakaputa.
Te Whakapai Ake i ngā Taupānga CASE
Ka horapa te whānuitanga o te Catalyst MB20 ki te wāhanga CASE, ka whakapai ake i te mahi a ngā paninga, ngā piripiri, ngā hiri, me ngā elastomers. I roto i ngā paninga, ka āwhina te MB20 ki te whakatutuki i tētahi mutunga maeneene, ōrite me te pakari me te ātete ki ngā āhuatanga taiao. Mō ngā piripiri me ngā hiri, ka whakarite te whakakorikori i te tere o te whakamaroke me ngā āhuatanga piri kaha, he mea nui mō ngā tono ahumahi me ngā tono kaihoko. Ka whai hua ngā elastomers i te pai ake o te ngāwari me te kaha miihini e whakaratohia ana e te whakakorikori whai hua o te MB20.
Te Mahi Tahi me ngā Amine Tuatoru
Ko tētahi o ngā āhuatanga tino hira o MB20 ko tōna kaha ki te mahi tahi me ngā amine tuatoru. He rongonui ngā amine tuatoru hei kaiwhakaoho tahi i roto i te matū polyurethane, e whakarei ake ana i te whakaekenga nucleophilic ki ngā rōpū isocyanate. Ina whakamahia ngātahi me MB20, ka tere ake te tauhohenga polyurethane me ngā tukanga whakamaroke e ngā amine tuatoru. Ehara i te mea ka tere ake te tere o te tauhohenga anake tēnei pānga mahi tahi, engari ka whakapai ake hoki i ngā āhuatanga whānui o te hua whakamutunga, ahakoa he pahuka, he paninga, he piripiri, he hiri rānei.
Whakamutunga
Ko te Catalyst MB20 he whanaketanga nui i roto i te whakaterenga polyurethane, e whakakotahi ana i ngā painga o te matū bismuth waro me te whānuitanga e hiahiatia ana mō ngā tono polyurethane maha. Ko tōna kaha ki te mahi tahi me ngā amine tuatoru ka whakarite kia tere ake te wā whakamaroke me te pai ake o te mahi hua a ngā kaihanga. I a ngā ahumahi e rapu tonu ana i ngā otinga pumau me te whai hua, ka tū te MB20 hei whakaterenga e tutuki ana i ēnei tono, e akiaki ana i te auahatanga i roto i te mākete polyurethane.
