4,4′-Methylenebis(2-ethyl-6-methylaniline) / MMEA Nama CAS 19900-72-2
Ko te 4,4'-Methylenebis(2-ethyl-6-methylaniline) / MMEA, nama CAS 19900-72-2, e whakamahia ana hei whakaroa mekameka mō ngā elastomers polyurethane me te hei kaiwhakaora mō te kapia epoxy hei whakapai ake i ngā āhuatanga ā-pūkaha me te hihiri o ngā hua. Ka taea hoki te whakamahi i te MED hei matū matua mō ngā polyimides me te hei takawaenga mō te hanganga rauropi.
He pai mō te whakarewa i te polyurethane (CPU), te polyurethane thermoplastic (TPU), ngā elastomer RIM me te polyurea rehu i roto i te mara polyurethane. Ka taea hoki te whakamahi i te MED mō te tukatuka, te whakarite i mua me ngā paninga matū ārai-waikura i roto i te mara kapia epoxy. Ka whakamahia te MED i roto i te hanganga o ngā prepolymer, tae atu ki te polyether me te polyester.
He otinga tino pai a MED mō ngā hua kua oti te hanga e hiahia ana ki te tae mārama me te ārai i te koroheketanga. Ka taea te whakamahi i te MED me ētahi atu matū whakaora momo amine kia pai ake ai ngā āhuatanga ā-tinana.
He momo amine te MED me te MOCA. Heoi, he pai te MED mō te taiao, ā, he iti ake te poke i te MOCA. Ka taea hoki e te MED te whakakapi i te MBOEA me te HQEE i runga i ngā hua PU, ahakoa te CPU (polyurethane whakarewa) te TPU rānei (polyurethane thermoplastic). Pērā i te MOCA, he tino pai te ātete wera o ngā elastomers momo-MED ina mahi ana i runga ake i te 120℃.
He mea whakaroa me te whakamaroke mekameka kakara te MED/MMEA. Nā ngā ture tino pakari mō te whakamahi i te MOCA, ko te MED hoa-taiao, kāore i te poke, he kōwhiringa pai rawa atu mō ngā momo tono. He maha ngā whakamahinga o ngā polyurethane MED-based, ā, he mana hoahoa hoki, he kaha teitei, me te pupuri tonu i tōna ngāwari. He pakari, he ātete hoki ngā hua kua oti te momo MED, ā, he pai mō ngā tono uaua, pērā i ngā papa parepare, ngā wira, ngā roera, ngā potae forklift, ngā wāhanga mīhini me ētahi atu. Hei tāpiri, ka taea hoki te whakamahi i te MED hei mea piriti i runga i te haurua-kawe me te mea whakamaroke i runga i te epoxy me te polyurea.
Mō te 4,4'-Methylenebis(2-ethyl-6-methylaniline) / MMEA puta noa i te ao. Ko tā mātou whakaputanga ā-tau he 400 tāne mita.
Tākai: 180kgs/pēke; 300kgs/pēke, 18kgs/pēke
Te rokiroki me te kawe: Rokiroki ki tētahi wāhi e pai ana te hauhautanga. Nā te mea he iti te waiora o tēnei hua, kaua e pā ki te wai, kaua hoki e whiti te rā. Hiritia te ipu kia mau i muri i te whakamahinga. I taua wā, kāore e taea te rongoa me ngā matū waikura.
Te roa o te oranga: 12 marama
