Ko te pahuka polyurethane, he rauemi maha-whakamahinga, ā, e whakamahia whānuitia ana i roto i ngā ahumahi maha, ka hangaia mā roto i tētahi tukanga matū matatini e uru ana te tauhohenga i waenga i ngā polyol me ngā polyisocyanates. Ko tētahi o ngā mahi nui o tēnei tukanga ko tetauhohenga whakapūkara, e hua ake ai te hanganga o te whatunga polyurethane, e hoatu ana ki te pahuka ōna āhuatanga e hiahiatia ana.
He aha te Gelation i roto i te Polyurethane Foam?
Ko te whakapūkara e pā ana ki te wāhanga tuatahi o te tauhohenga o te polyol (he polyether, he polyester polyol rānei te nuinga) me te isocyanate (pēnei i te MDI, i te TDI rānei) hei hanga i tētahi whatunga polymer hono-whiti. Ko tēnei whatunga, e mōhiotia ana ko te polyurethane, ka whakarato i te pahuka ki tētahi hanganga pakari, ngāwari rānei, i runga i te hanganga.
I te tukanga whakapūkara, ka hangaia he hononga urethane i waenga i te polyol me te isocyanate. I te haere tonu o te tauhohenga, ka piki ake te matotoru o te ranunga, ā, ka huri te pūnaha wai hei matū rite ki te gel. Ko te whānuitanga me te tere o tēnei tauhohenga ka whakawhirinaki ki ētahi āhuatanga, tae atu ki te momo polyol me te isocyanate i whakamahia, te pāmahana, te nui o te makuku, me te mea nui, te whakakorikori i whiriwhiria.
Te Tūranga o ngā Kaikōkiri i roto i te Whakakorikori
He mea nui ngā whakakorikori mō te whakahaere i te tere o te tauhohenga whakawairakau, kia mau ai te whatunga polyurethane.Ka whakateretere i te tauhohenga i waenga i ngā polyol me ngā polyisocyanates, ka āwhina i te whakawhiti maeneene mai i te hanganga wai ki te hanganga pahuka totoka.
Ko tētahi o ngā whakakorikori matua i roto i te hanga pahuka polyurethane ko teMXC-T9, he whakakorikori whakarewa kaha i hangaia mō ngā tauhohenga whakakorikori. Ka whakaratohia e MXC-T9 te mana whakahaere pai rawa atu i te tere tauhohenga, e whakarite ana i te mahi ōrite me te pumau puta noa i te tukanga pahuka. He tino pai mōpahuka polyurethane ngawarite whakaputanga, ā, koia te whakakorikori matua mō te whakarewatanga i roto ipahuka polyurethane e hangai ana ki te polyether.
Ngā Āhuatanga Matua oMXC-T9
- Kaiwhakaoho Kaha, Pūmau hoki:He whakakorikori whakarewa te MXC-T9 e tuku ana i te ngohe whakakorikori kaha, pumau hoki puta noa i te tauhohenga, e hua ake ai he pahuka kounga teitei me ngā āhuatanga ōrite e taea te matapae.
- Te maha o ngā whakamahinga:Ahakoa e whakamahia ana mō te tauhohenga gelation i roto i te pahuka polyurethane e ahu mai ana i te polyether, ka taea hoki e MXC-T9 te mahi heiārai matehei whakapai ake i te pumau me te roa o te pahuka.
- Ngā Āhuatanga Pahuka Whakarei:Mā te whakahaere i te tukanga whakapūkara, ka āwhina a MXC-T9 ki te whakaputa pahuka me te hanganga pai, te pakeke, me te manawanui, e mea nui ai i roto i te hanga pahuka polyurethane papatipu ngohengohe.
Whakamutunga
Ko te tauhohenga whakapūkara he taahiraa matua i roto i te hanganga o te pahuka polyurethane, ka tauhohe ngā polyol me ngā polyisocyanate hei hanga i tētahi whatunga polyurethane pumau. Mā te whakamahi i tētahi whakakorikori whai hua pēnei i teMXC-T9 Ka whakarite kia maeneene te tukanga, ā, ka puta he pahuka kounga teitei me ngā āhuatanga e hiahiatia ana. Nā te pumau pai me te mahi ōrite o te MXC-T9, he mea nui tēnei hei whakakorikori mō te hanga pahuka polyurethane papa ngohengohe, ā, he mea nui tēnei hei whakatutuki i ngā hua pahuka pono, mahi teitei.
