He kaiwhakarato a Mingxu Chemicals i te ao o ngā whakakorikori polyurethane, ā, inaianei ka whakaatuhia e mātou te whānuitanga me ngā tono taketake o ngā pahuka ngohengohe polyurethane me te tūranga o ā mātouMXC-A1te whakakorikori i roto i tā rātou hanga. He whānuitia te whakamahinga o ngā pahuka ngohengohe polyurethane nā te mea he ngāwari ki te urutau me te ngāwari, e tautoko ana i ngā ahumahi pēnei i ngā taonga whare, ngā motuka, ngā hākinakina, ngā rongoā me ngā takai. Me ngā āhuatanga whakarei ake pēnei i te urunga, te whakamarumaru oro me te tātari, ko ngā pahuka ngohengohe te rauemi whiriwhiri mō ngā tono mahi teitei.
Ka puta ngā pahuka ngohengohe polyurethane mā te tauhohenga matū i waenga i ngā diisocyanate me ngā polyol, e rua nei i ahu mai i te hinu mata. Hei tāpiri, ka taea te tiki polyol mai i ngā hinu taiao hou, ka whakarato i ngā kōwhiringa whakaputa pumau. Ina honoa, ka tauhohe te diisocyanate me te polyol ki te hanga pahuka me te hanganga honikoma. He ngāwari te pēhi, he ngāwari, he pai hoki ngā āhuatanga whakaruruhau o tēnei hanganga, he mea pai mō te whakamahi i roto i ngā taonga, ngā moenga, ngā nohoanga motuka, ngā taputapu hākinakina, ngā taputapu hauora, ngā takai, ngā hu me ngā whāriki whāriki. Ka whakarei ake hoki te hanganga o te pahuka ngohengohe polyurethane i ngā āhuatanga whakamarumaru oro me te tātari, ka whakawhānui ake i tōna whai huatanga i roto i ngā mara maha.
Ko te mea nui ki te whakatutuki i te kounga me te hanganga pahuka pumau ko te whakamahinga o ngā whakakorikori me ngā tāpiringa motuhake. Ko tā mātou whakakorikori MXC-A1, e kiia nei koBDMAEE(Tau CAS: 3033-62-3) ko N,N,N',N' -tetramethyl-2,2′ -oxybis (ethylamine) rānei, he whakakorikori amine tuatoru tino kaha, e whakamahia ana i te nuinga o te wā i roto i te hanga hua pahuka ngāwari, inā koa mō te hanga hua RIM teitei. Ka hangaia te pahuka polyurethane mā te tauhohenga o te diisocyanate me te polyol. Ka whakatairangahia e tēnei wai kore tae ki te kōwhai paku ngā tauhohenga urea (wai-isocyanate) i roto i ngā pahuka polyurethane ngohengohe me te pakari, e whakarato ana i te mahi whakakorikori me te whiriwhiri i te wā o te tukanga pahuka.
Nā ngā āhuatanga ahurei o MXC-A1 e pai ai mō te whakaputa i te nuinga o ngā momo pahuka ngāwari, inā koa ngā hua whakahoki-teitei me ngā tono Tauhohenga Injection Molding (RIM). Mā te whakarerekē i te rahi o te mirumiru i te wā o te tauhohenga i waenga i ngā polyol me ngā isocyanates, ka taea e ngā whakakorikori amine me ngā surfactants te whakarite i te kiato me te pakari o te pahuka. Ko ētahi atu tāpiringa pēnei i ngā aukati mura me ngā kaihoko bacteriostatic ka whakarei ake i te whānuitanga o te tono o te pahuka, inā koa i roto i ngā rāngai rererangi, motuka, waho, me te moana.
Mā te whakamahi i tā mātou whakakōkī MXC-A1, ka taea e ngā kaihanga pahuka ngāwari te whakatutuki i te whakaputanga whai hua, te ōritetanga pahuka kounga teitei me te kanorau o te whakamahinga. Ki te hiahia koe ki te ako atu mō MXC-A1 me ētahi atu whakakōkī, tēnā whakapā mai ki a mātou kia kitea ai me pēhea e taea ai e ā mātou whakakōkī te whakatutuki i ō hiahia whakaputa pahuka ngāwari polyurethane.
