Kupu Whakataki
Ko ngā elastomers polyurethane he momo polymer maha-whakamahinga, he mahi-teitei e whakamahia ana puta noa i ngā ahumahi tae atu ki te motuka, te hanga, te hu, me te hanga ahumahi. Nā te whakakotahitanga ahurei o te pakari, te ngāwari, me te ātete matū e pai ai mō ngā taiao uaua. Ko tētahi wāhanga nui, e warewarehia ana i roto i te whakaputa elastomers polyurethane kounga teitei, ko te pūnaha whakakorikori—ina koa ko ngā whakakorikori amine, e āwhina ana ki te whakahaere i te kōtaha tauhohenga me ngā āhuatanga whakamutunga o te rauemi.
I MINGXU NEW MATERIALS, he tohunga mātou ki te whakaputa i ngā whakakorikori polyurethane mahi-teitei. Ko tētahi o ā mātou hua matua, ko te MXC-37 (DMAEE), he mahi nui tāna i roto i ngā momo tono elastomer mā te whakarei ake i te tere o te tauhohenga me te whakarite kia iti ngā tukunga me te iti o te haunga.
Ngā Whakakōkī Polyurethanei roto i ngā Pūnaha Elastomer
I roto i ngā hanganga elastomer polyurethane, ka whakahaerehia e ngā whakakorikori te tere o ngā tauhohenga matua e rua:
1. Te tauhohenga whakapūkara (polyol me te isocyanate)
2. Te tauhohenga pupuhi (wai me te isocyanate)
He rerekē ki ngā pahuka, he iti noa te pupuhi e hiahiatia ana mō ngā elastomers kia mau tonu ai te pakari o te hanganga. Heoi, i roto i ētahi whakamahinga pēnei i ngā elastomers moroiti, i te whakakoi werohanga tauhohenga rānei (RIM), he mea nui te taurite pai i waenga i te pahuka me te whakakoi hei whakatutuki i te matotoru, te pakari, me te mutunga o te mata e hiahiatia ana.
MXC-37 (DMAEE)He Whakakōkī Amine Mahi-Tiketike mō ngā Elastomers
Ko te MXC-37, e mōhiotia ana ko te 2-dimethylaminoethylethanol (DMAEE), he whakakorikori amine tuatoru i hangaia hei whakarato i te mahi tino pai i roto i ngā pūnaha elastomer me ngā pūnaha pūtau iti. He tino whai hua i roto i ngā whakatakotoranga he nui te ihirangi wai, he mea nui te whakahaere i te huka me te whakahaere i te haunga.
Ngā Painga Matua o te MXC-37 i roto i ngā Elastomers:
Hoahoa iti te kakara, kore-tukunga:Hei whakakorikori kore-tukunga, iti hoki te haunga, ka whakaitihia e te MXC-37 te haunga amine āhua motuhake i roto i ngā wāhanga elastomer kua oti—he mea tino nui ki roto i ngā whare motuka me ngā taonga kaihoko.
Te Mahi Huka Nui:Ahakoa i roto i ngā pūnaha elastomer he iti, he whakahaeretia rānei te ihirangi pahuka, ka tautoko a MXC-37 i te hanganga pūtau ōrite me te whakahaere i te kiato pai ina hiahiatia ngā pānga pūtau moroiti.
Hototahi Pai rawa atu:He hototahi te MXC-37 ki te whānuitanga o ngā pūnaha polyester me te polyether, e tika ana mō ngā elastomers ngohengohe me ngā elastomers pakari, tae atu ki te pahuka ngohengohe whakaū e hangai ana ki te ester me te takai pahuka pakari.
Ngā Whakamahinga Maha: He mea whakamahi noa i roto i:
Ngā elastomers polyurethane moroiti (hei tauira, ngā kapu hū, ngā okiokinga ringa)
Ngā pūnaha RIM (ngā parepare waka, ngā panera)
Ngā pahuka elastomer ngāwari-teitei
Ngā elastomers tākai hanganga me te whakamarumaru
He aha koe i whiriwhiri ai i te MXC-37 mō tō pūnaha elastomer?
Ko te hanga i ngā elastomers polyurethane mahi-teitei e hiahiatia ana te tika, te ōritetanga, me te mana whakahaere. Ka tukuna e MXC-37 ēnei mea katoa, me te āwhina hoki i ngā kaihanga hanga kia tutuki i ngā paerewa taiao me te hauora mahi pakari ake. Ahakoa kei te whakawhanake koe i ngā wāhanga motuka mama, i ngā wāhanga ahumahi pakari rānei, ka whakarei ake a MXC-37 i te kounga o te tukanga me te hua.
Whakamutunga
I te mea kei te piki haere tonu te hiahia mō ngā pūnaha elastomer polyurethane ma, pai ake hoki, he mea nui ake i ngā wā katoa te whiriwhiri i te whakakorikori tika. Ka tukuna e te MXC-37 (DMAEE) te mahi, te tutuki i ngā whakaritenga taiao, me te whānui o te whakamahinga e hiahiatia ana hei whakatutuki i ngā whakaritenga hanga hou.
Whakapā mai ki a mātou i tēnei rā kia mōhio ai koe me pēhea te whakamahi a MXC-37 i tō hanganga elastomer polyurethane.
