Pūtake Ngota me te Kōwhiringa Whakakorikori
Hanganga ngota o te MXC-DMI a Ming Xu Chem (CAS 1739-84-0), he whakakorikori whakaora kaha e ahu mai ana i te imidazole.
Ko te hanganga taketake o MXC-R70 e whakaatu ana i tōna pumau tino pai me te mana whakahaere tika i ngā whakatakotoranga PU:
-
Mowhiti Imidazole Heterocyclic:He rerekē tēnei i ngā hanganga amine tuku iho, ka whakaratohia e te mowhiti matua imidazole he matūriki taurite e tino taurite ana i ngā tauhohenga pupuhi me te whakapūpū, kia rite ai te tipu o te pūtau.
-
Pūmanawa Tauhohenga Teitei:Mā te Uara Hydroxyl pakari (542 mg/KOH/g), ka tukuna he pūmanawa tauhohenga tino pai i roto i te polyol premix, e āhei ai te iti o ngā taumata utaina kia tutuki ai te pānga catalytic e hiahiatia ana.
Te Whakaora Mata me te Mahi Piri
He whakakorikori wai mahi-teitei te MXC-R70 i hangaia mō te hononga-whiti tika me ngā āhuatanga miihini tino pai i roto i ngā pūnaha PU.
Mō ngā kaihanga raina tonu me te pahuka rehu, ka mahi a MXC-R70 hei whakaterenga kaha i muri i te whakamaroke hei whakatau i ngā hapa hanganga noa:
-
Whakakore i te Pakaru o te Mata:He mea hanga motuhake hei akiaki i ngā wāhanga whakamutunga o te tauhohenga isocyanate, kia ea rawa ai te pakarukaru o te mata (ngāwari) e puta pinepine ana i te tere o te whakakorenga.
-
Te Piringa Papa Whakarei Ake:Mā te hanga i tētahi anga pūmua pakari ake, kua whakamaroketia katoatia ki te atanga pahuka, ka tino whakapai ake i te kaha o te here ki ngā papa pēnei i te whakarewa, te rakau rānei.
-
Hototahi Pūnaha HFO:He tino pai te mahi a tēnei mea i roto i ngā pūnaha pupuhi HFO hou me ngā pūnaha pupuhi-tahi wai, kia mau tonu ai te pikinga maeneene me te pumau o ngā āhuatanga.
Te Whai Hua o te Tukanga me te Pūmautanga Whakahaere
Ka arotahi mātou ki te whakarato i ngā otinga mahi-teitei e whakauru pai ana ki roto i ō taputapu wheketere aunoa, ā, ka whakapai ake i te haumaru o te wāhi mahi:
-
Pūmautanga mō te Takurua:Ahakoa kei raro iho i te -10°C te ira tio o tēnei whakakorikori, ka noho pumau tonu, ā, ka ārai i te whakawhaititanga i te wā e rongoatia ana, e kawehia ana hoki i te rangi makariri.
-
Tino Iti te Matatini:I te 10 mPa.s noa iho, ko tōna rere rite tonu ki te wai ka māmā te papu, ka tino pai te whakaranu, me te tino tika o te inenga i roto i ngā mīhini pahuka pēhanga teitei.
-
Kōtaha Kakara-Iti:Ki te whakaritea ki ngā amine pūngāwerewere tuku iho, he iti ake te haunga o te MXC-R70, e whakapai ake ana i te taiao mahi i runga i te papa wheketere me te ataahua o te hua whakamutunga ki te mākete.
