I roto i te rangi whetu kanapa o ngā rauemi mata matū, kua noho te m-phenyldimethylamine, me ōna āhuatanga ahurei me te tino pai, hei huānga matua nui i roto i te maha o ngā ahumahi, e ārahi ana i tētahi panonitanga ahumahi me te auahatanga i muri i tētahi.
He wai kore tae te M-phenyldimethylamine i te pāmahana rūma, ko tōna taumaha ngota he 136.194, ko tōna mātotoru he 1.1±0.1 g/cm³, ko tōna ira kohua he 247.0±0.0 °C (760 mmHg), ā, ko tōna ira rewa he 14°C. I roto i tōna hanganga ngota, ka honoa pai te rōpū amine tuatahi aliphatic me te mowhiti benzene, ka whakawhiwhia ki a ia he raupapa o ngā āhuatanga whakamiharo.
Te "Mīhini Tino Pai" i roto i te mara o te whakamaroke epoxy
Hei matū whakaora i te kapia epoxy, ko te m-phenyldimethylamine te kaiārahi i roto i te umanga. Nā te mea kei roto ngā rōpū amine tuatahi aliphatic, ka taea e ia te whakaputa tere i ngā pānga whakaora i te pāmahana rūma, ka whakapoto i te huringa whakaputa me te whakarei ake i te pai o te whakaputa. Ehara i te mea he tino pai te ātete wera o te hua kua rongoatia, ā, ka taea te noho pumau i roto i ngā taiao pāmahana teitei, he pai ake i ngā polyamines aliphatic noa; he tino pai hoki te ātete matū. Ahakoa he whakarewa waro pēnei i te toluene, he mea waikura rānei pēnei i te waikawa whanariki 10% wt, he uaua ki te kino. Nā tēnei āhuatanga i taea ai e ia te tiaho mārama i roto i ngā mara o ngā piri hiri pākahiko me ngā piri pou whakamutunga. Me ngā painga o te matotoru iti, te rere ngāwari me te urunga pai, ka whakarite kia tino hiritia te piri, kia ātete ki te mimiti o te hau waikawa me te wai waikawa, me te tū atu ki ngā pānga kaha o waho, kia tiakina ai te mahi haumaru me te pumau o ngā pākahiko. I taua wā, i roto i te whakamahinga o ngā paninga ārai-waikura mō te whakatika piriti, te paninga paipa, ngā ipu kaipuke, ngā papa, me ētahi atu, ka taea e te m-phenylenediamine, me te whakakotahitanga me te kapia epoxy, te whakaatu i te piri pai ahakoa i roto i ngā taiao makuku, e ātete ana i ngā āhuatanga uaua me te whakaroa i te roa o te ora o ngā whare.
"Whakatairanga Auahatanga" mō ngā ahumahi kanorau
I roto i te hanga kapia polyurethane me ngā paninga, ko te m-phenyldimethylamine te rauemi mata matua, ā, e whai wāhi ana ki te hanganga o ngā hanganga ngota ngota mahi-teitei. Ka taea e ia te whakarei ake i te ngāwari, te ātete kakahu me te ātete pānga o ngā rauemi polyurethane, me te whakawhiwhi i ngā paninga ki te ātete huarere me te kanapa pai. He whānuitia te whakamahinga i roto i te whakapaipai mata me te tiaki i roto i ngā taonga whare, ngā motuka, te hanga me ētahi atu mara. I roto i te mara o ngā tāpiri rapa, ka taea e tana tāpiri te whakapai ake i te tukanga whakamomona o te rapa, te whakarei ake i te kaha, te ngāwari me te ātete koroheketanga o ngā hua rapa, me te whakapai ake i te kounga o ngā hua rapa mai i ngā potae ki ngā hiri rapa. Hei tāpiri, he monomer nui hoki te m-phenyldimethylamine mō te hanga rauemi nairona mahi-teitei pērā i te polyadipylm-phenyldimethylamine (MXD6). Ko te MXD6, me tōna hanganga ahurei e whakakīia ana e te m-phenyldimethylamine, he āhuatanga ārai teitei (ko te urunga hāora he 1/10 noa iho o te PA6), he kaha me te pakari teitei (te kaha kume tae atu ki te 280MPa, te modulus piko tae atu ki te 24GPa), he ātete wera pai (te pāmahana whakararu wera tae atu ki te 73.8℃, 1.8MPa), me te tere mimiti wai iti. Kua whakaatuhia e ia te kaha tono nui i roto i ngā mara matatau pēnei i ngā rauemi mama mō ngā karetao, ngā wāhanga mō ngā waka pūngao hou, me ngā takai kai kounga teitei, ā, kua noho hei kaha matua e akiaki ana i te whakapai ake i te ahumahi. Ehara i te mea koinā anake, i roto i te maha o ngā ahumahi pēnei i ngā kirihou photosensitive, ngā patu pepeke, ngā kaihoko whakaoti muka, ngā aukati waikura, ngā kaihoko chelating, ngā hinu whakahinuhinu, me te tukatuka pepa, ko te m-phenyldimethylamine, me ōna āhuatanga ahurei, e whakarato ana i te kaha akiaki tonu mō te auahatanga hua me te arotau mahi.
Mai i te pūtake whakaputa ki te whakamahinga whakamutunga, ka piri pono te m-phenyldimethylamine ki te mana whakahaere kounga. Ka whakamahia e te tukanga whakaputa ngā hangarau matatau, mai i te ranunga o te m-xylene me te p-xylene, kātahi ka pāngia e ngā tauhohenga waikura me te hau me te haukini hei whakaputa i te m-xylene me te p-phenyldimethylnitrile. Muri iho, ka pāngia e ngā mahi tino tika pērā i te horoi wai, te whakamaroke, me te hauwaiwaitanga catalytic, ā, ka puta he hua tino parakore. Ka pāngia ia puranga hua e ngā whakamātautau tino pakari hei whakarite i te parakore o te ≥ 99.0%, me te pumau me te pono o ngā tohu katoa, e whakarato ana i tētahi whiringa whakamarie ki ngā kaihoko. Ka tākaihia te hua ki roto i ngā ipu kirihou 200-kirokaramu hei kawe me te rokiroki watea. Me rongoa ki tētahi wāhi hauhautanga me te hauhautanga pai, me te piri pono ki ngā ture rokiroki me te kawe mō ngā matū mura me ngā matū paitini kia kore ai e pāngia te kounga o te hua.
Ko te M-phenyldimethylamine, me tana mahi tino pai hei turanga me ngā momo tono hei parirau, kei te āwhina i ngā momo ahumahi ki te pakaru i ngā arai hangarau me te tīmata i tētahi haerenga hou o te kounga teitei me te whanaketanga auaha ake. Hono atu ki te m-phenyldimethylamine me te awhi tahi i te heke mai mutunga kore o te umanga matū!
