Kaiwhakaoho Whakatipu Matatau mō ngā Pūnaha PU me te PIR Mahi-Teitei
He whakakorikori amine wai motuhake a MXC-41 e whakatairanga kaha ana i te tauhohenga trimerization i roto i ngā pahuka mārō.
He tino motuhake te MXC-41 (1,3,5-Tris[3-(dimethylamino)propyl]hexahydro-1,3,5-triazine) hei whakakorikori amine tuatoru. He rongonui mō ōna kaha whakakorikori kaha, koinei te paerewa ahumahi mō te hanga pahuka pakari polyisocyanurate (PIR) ātete-mura, me te whakarato hoki i te whānuitanga tino pai i roto i ngā pūnaha elastomeric matatau me te pakari-teitei.
Te Hanganga Ngota me te Matua Whakakotahitanga
Te hanganga ngota o te MXC-41 a Ming Xu Chem (CAS 15875-13-5), te whakakorikori paerewa-umanga mō ngā whakatakotoranga PIR.
Ko te hoahoa ngota ngota taketake o MXC-41 te mea nui ki te wetewete i te pumau wera pai rawa atu i roto i ngā tono pahuka pakari:
-
Mowhiti Hexahydro-s-triazine:He matua triazine motuhake e ono ngā mema, ā, ka kaha te whakatairanga a tēnei whakakorikori i te tauhohenga trimerization o ngā isocyanates.
-
Te Hanganga Isocyanurate Pūmau i te Wera:Mā te akiaki i te hanganga o ngā mowhiti isocyanurate pakari, ka whakarei ake i te ātete ahi ā-roto, te pumau wera, me te kaha miihini o ngā rauemi whakamahana kua oti.
Te Āraitanga PIR me te Mahi Pahuka Mārō Arā Atu Anō
Mō ngā kaihanga o ngā panera whakamarumaru matotoru me ngā pahuka rehu, ka tukuna e MXC-41 ngā painga hanganga me te haumaru nui:
-
Ātete Ahi Tino Pai:Nā tōna kaha ki te whakaputa whatunga polyisocyanurate (PIR) kaha, ka tutuki i ō hua pahuka mārō ngā paerewa mura me te haumaru ahi o te ao e kaha haere ana.
-
I arotauhia mō ngā Pūnaha Pupuhi-Wai:He tino pai te mahi a tēnei matū i roto i ngā whakatakotoranga pakari wai-katoa, i ngā whakatakotoranga pupuhi-tahi rānei, e tuku ana i tētahi āhua whakaterenga tino kaha engari he taurite e ārai ana i te mimiti me te pupuri i tētahi tauhohenga maeneene.
-
Te Pūmautanga Ahu Tino Pai:Ka āwhina i tētahi hanganga pūtau ōrite, pai hoki, e hua tika ana ki te kaha pēhi me te pumau o ngā āhuatanga i roto i ngā papa whakamahana matotoru.
Te Whānuitanga o ngā Pūnaha Pūtau-iti me te Pūmautanga-Tiketike
Haunga te whakamarumaru pakari, he tino whai hua te MXC-41 hei kaiwhakaoho maha-whakamahinga puta noa i ngā rāngai polyurethane motuhake:
-
Te Whakaora i te Elastomer Pūtau-iti:Ka whakapai ake i te āhua pakari me ngā āhuatanga ā-tinana o ngā elastomers pūtau-iti, kia mau ai te pakari me te tere o te tango.
-
Arotautanga Pahuka HR:I roto i ngā nohoanga whakarewa Ātete-Teitei (HR) me ngā pahuka papa rakau, ka mahi tahi me ētahi atu whakakorikori hei whakatutuki i te hononga whakawhiti tino pai me te hanganga pūtau-tuwhera pai rawa atu mō te whakamarie nui.
Te Whai Hua o te Tukanga me te Pūmautanga Whakahaere
Ka mau tonu mātou i ngā tawhā whakahaere kounga tino pakari hei whakarite i te tika o te inenga me te pono o te hanganga i roto i tō wheketere aunoa:
-
Te Mahi Whakakorikori Kaha:Mā te uara amine teitei, mai i te 485 ki te 505 mgKOH/g, ka kaha te tauhohenga ahakoa i ngā taumata horopeta tino iti, ka whakaitihia ai ngā utu hanga katoa.
-
Ngā Āhuatanga Wai Tino Pai:He wai mārama, he tino iti te matotoru (26–33 mPa·s i te 25°C), ā, ka oati ka ngāwari te papu, ka maeneene te whakaranu, ā, ka tino tika te ine a te mīhini.
-
Teitei o te Parakore kua Whakamanahia:Mā te iti rawa o te parakore o te 98% me te nui o te wai e tino whakahaeretia ana (mōrahi 0.5%) ka whakakorea te mōrearea o ngā uruparenga taha kāore e hiahiatia, ka tiaki i ō ranunga polyol matatini mai i te pirau wawe.
