He mea nui te mahi a ngā whakakorikori polyurethane i roto i te hanga polyurethane, hei kaha akiaki i muri i ngā tauhohenga matū e hanga ana i ēnei rauemi maha-whakamahinga. I roto i ngā whakakorikori maha e wātea ana, ko te MXC-T120 te mea tino kaha me te whai hua mō ngā momo tono polyurethane, mai i te pahuka rehu ki te polyurethane pakari me ngā hua whakakorikori ngāwari teitei. Te mārama ki te mahi a ngā whakakorikori polyurethane me ngā painga oMXC-T120he mea nui mō te arotau i ngā tukanga whakaputa me te whakatutuki i te mahi rauemi tino pai.
Ko te whakakorikori, i te nuinga o te wā, he matū e whakanui ake ana i te tere o te tauhohenga matū me te kore e pau i roto i te tukanga. I roto i te horopaki o te hanga polyurethane, he mea nui ngā whakakorikori hei whakatere i te tauhohenga i waenga i ngā polyol me ngā isocyanates, ngā wāhanga matua o te polyurethane. Ko tēnei tauhohenga, e mōhiotia ana ko te gelation, ka hanga i te matrix polymer o te polyurethane. Ko te MXC-T120, he whakakorikori e ahu mai ana i te dibutyltin, he tino whai hua ki te whakahaere i tēnei tauhohenga, e tuku ana i te mahi whakakorikori teitei me te pumau hydrolytic kua whakarei ake.
Ko tētahi o ngā mahi matua a ngā whakakōkī polyurethane pērā i te MXC-T120 ko te whakahaere i te wā whakakōkī. Mā te tere ake i te tukanga whakakōkī, ka āwhina ngā whakakōkī ki te hanga i tētahi whatunga pūmua pumau me te tere me te whai hua. He mea nui rawa tēnei i roto i ngā tono pērā i te rehu pahuka, he mea nui te whakamaroke tere hei pupuri i te āhua me te hanganga. Hei tāpiri, ko te MXC-T120'Mā te kaha o te mahi whakakorikori a te kamupene ka whakarite kia pumau, kia pono hoki te mahi puta noa i ngā momo hanganga polyurethane rerekē.
Haunga te whakahaere i te wā whakapūpū, he mahi nui anō hoki tā ngā whakakorikori ki te whakataurite i ngā tauhohenga taha, tae atu ki te tauhohenga o te wai me ngā isocyanate hei hanga hau waro hauhā (CO2). He mea nui tēnei tauhohenga ki te tukanga whakapūpū, e whakarato ana i ngā āhuatanga e hiahiatia ana pērā i te whakamarumaru me te whakangāwari ki ngā pahuka polyurethane. Heoi, mā te nui o te hanga hau ka arahi pea ki ngā hapa me te kounga o te rauemi e ngoikore ana. He tino pai a MXC-T120 ki te whakahaere i ēnei tauhohenga taha, e whakarite ana i te taurite pai i waenga i te hanganga polymer me te hanga hau, ka hua ake he pahuka kounga teitei me te hanganga pūtau ōrite.
Ki te whakatauritea ki ngā whakakōkī amine, i ahu mai i te haukini (NH3) ā, he rerekē te mahi i runga i tō rātou hanganga me te taketake, he pai ake te mahi a te MXC-T120 i runga i te pumau o te wai. Ko ngā whakakōkī amine, inā koa ko ngā amine tuatoru, e whakamahia whānuitia ana i roto i te hanga pahuka nā te mea he kaha ki te whakatairanga i te hanganga CO2. Heoi, ka taea hoki e rātou te whakaputa i te piki me te aro ki te makuku, ka pā pea ki te pumau o te rauemi mo te wā roa. Ko te MXC-T120, me tōna hanganga dibutyltin, ka whakarato i te ātete nui ake ki te wai, ka whakarite kia roa, kia pumau hoki ngā hua polyurethane ahakoa i roto i ngā āhuatanga taiao uaua.
Hei whakamutunga, ko tewhakakorikori polyurethaneHe matū whakakorikori kaha, he maha hoki ngā whakamahinga o te MXC-T120, e whakapai ake ana i te pai me te kounga o te hanga polyurethane. Nā tōna kaha whakakorikori teitei, tōna pumau waikura pai rawa atu, me tōna kaha ki te whakataurite i ngā tauhohenga taha, he mea tino pai mō ngā momo whakamahinga, mai i te pahuka rehu ki ngā hua whakakorikori pakari me te ngāwari. Mā te whakamahi i ngā painga o te MXC-T120, ka taea e ngā kaihanga te whakatutuki i ngā rauemi polyurethane pai rawa atu me te mahi me te roa kua whakarei ake.
