E whakamahia whānuitia ana ngā pahuka ngāwari polyurethane i roto i ngā ahumahi maha nā te mea he ngawari, he pakari, he maha hoki ngā whakamahinga. He mea nui te mahi a ngā whakakorikori polyurethane i roto i te tukanga whakaputa hei whakatutuki i ngā āhuatanga e hiahiatia ana pērā i te ōritetanga o ngā pore, te pakari, me te piri pai ake. E rua ngā whakakorikori motuhake, ko MXC-BDMA me MXC-70, e whakaatu ana i te hiranga o ngā whakakorikori kua whiriwhiria marietia i roto i ngā hanganga pahuka ngāwari.
1. MXC-BDMA (CAS 103-83-3)– Kaiwhakaoho Benzyl Dimethylamine
He whakakorikori whānuitia te MXC-BDMA i roto i te pahuka ngohengohe nui o te polyester polyurethane, te pahuka pakari o te polyurethane, me ngā paninga pepa me te piripiri. Ahakoa e whakamahia ana i roto i ngā pahuka pakari, he nui ngā painga ki te hanga pahuka ngāwari:
- Te Rerenga o te Wā:Mā te MXC-BDMA ka tino pai te rere o te wai i te tīmatanga, ka taea ai te rere maeneene o te ranunga polyurethane ki roto i ngā pokepokea ai me ngā poka, he mea nui tēnei mō ngā whakamahinga pahuka ngāwari.
- Ngā Pūwero Kotahi:Ka whai wāhi te whakakorikori ki te hanganga o ngā pūtau pahuka ōrite, he pai te hanganga. He mea nui te ōritetanga o te hanganga pūtau kia tutuki ai ngā āhuatanga pahuka ōrite pērā i te whakangāwari me te pakari.
- Te Whakapai Ake i te Piripiri:Mō ngā tono e hiahia ana kia piri te pahuka ki te papa, ka whakapai ake a MXC-BDMA i te piri, kia mau ai, kia roa ai hoki te hua.
2. MXC-70 (CAS 1739-84-0)– Kaiwhakaoho i te Amine
Ko te MXC-70 tētahi atu whakakorikori maha-whakamahinga, e whakamahia ana i roto i ngā hanganga pahuka pakari engari he nui ngā painga ki te hanga pahuka ngāwari, inā koa i roto i ngā pahuka ngāwari pakari (HR) me ngā poraka e hangai ana ki te ester:
- Te Whakapai Ake i te Pakaru me te Pakaru:Ka whakarei ake tēnei whakakorikori i hangaia mai i te amine i te tukanga whakamaroke, ka whakaiti i te pakarukaru o te hua whakamutunga, ka ngāwari ake ai te pahuka, ā, ka iti ake te ngawari ki te pakaru.
- Te Whakarei i te Kaha Kakariki:Ka whakapai ake hoki te MXC-70 i te kaha matomato o te pahuka, ka pai ake te whakahaere i ngā wāhanga tōmua o te hanga. He tino whai hua tēnei āhuatanga mō ngā pahuka ngāwari e whakamahia ana i roto i ngā tono motuka me ngā taonga whare, he mea nui te pakari.
- Ngāwari o te Taupānga:He pai te mahi a te whakakorikori me ngā whakatakotoranga polyester waro me ngā whakatakotoranga e hangai ana ki te ester, e tuku ana i te ngāwari ki te whakaputa pahuka ngāwari mahi-teitei.
Ka taea e tēnei tuhinga te whakamārama me pēhea te arotau a ngā whakakorikori e rua i te mahi pahuka, me te whakaatu i tō rāua pānga ki te hanganga pūtau ōrite me te whakapakari ake i te pakari, he mea nui ēnei mō ngā tono whakamahinga mutunga pēnei i ngā taonga whare, ngā moenga, ngā nohoanga motuka, me te whakamarumaru.
