Anga whakarewa whakarewaka kiia hoki ko te tukanga ka whakakikoruatia i mua i te kirikiri o te kirikiri kapia, te anga wera mo te whakarewatanga o te anga, te mahi whakarewa matua ranei. Ko te mea hanga matua ko te kirikiri kapia phenolic i mua i pania, he nui ake te utu i te onepu matomato me te onepu kapia furan. I tua atu, kaore e taea te whakamahi i tenei kirikiri.
Ko te tukanga whakarewa kirikiri whakamaroke-whaiaro a Furan (te tukanga nobake) e whakamahi ana i te kirikiri whakakikoruatia o te kapia furan hei hanga i te pokepokea ai. Whai muri i te whakaranu i te onepu taketake (he kirikiri kua whakahokia mai ranei), he kapia furan wai me te whakakorikori wai kia rite, ka whakakiia ki roto ki te pouaka matua (he pouaka kirikiri ranei), katahi ka whakakaha kia whakapakeketia ki roto i te pokepokea ai ki roto i te pouaka matua (he kirikiri ranei). pouaka) i te pāmahana rūma. Na ka hanga te pokepokea makanga matua makanga ranei, e kiia nei ko te whakamaroke-whaiaro pouaka makariri-matua (matua), tikanga whakapakeke-whaiaro ranei (matua).
No te mea i hanga te pokepokea ai i te pāmahana rūma, me te kore hiahia ki te wera, ka kiia hoki te makanga kirikiri whakapakeke-whaiaro te tukanga makanga kore-tunu. Ka taea te wehea te tikanga whakamaroke-whaiaro ki roto i te kapia furan waikawa-catalyzed me te tikanga whakapakeke i te kirikiri kirikiri phenolic, te tikanga whakapakeke i te kirikiri urethane me te tikanga whakapakeke-whaiaro phenolic monoester.
Hei kirikiri pouaka makariri e whakapakeke ana, ko te onepu kapia furan te kirikiri kirikiri tuatahi me te tino whakamahia i tenei wa i roto i te hangahanga Hainamana. Ko te nui o te kapia e tapirihia ana ki roto i te kirikiri hanga ko te tikanga 0.7% ki te 1.0%, a ko te nui o te kapia taapiri i roto i te kirikiri matua ko te tikanga 0.9% ki te 1.1%. Ko te ihirangi o te aldehyde kore utu i roto i te kapia furan kei raro iho i te 0.3%, a kua heke etahi wheketere ki raro i te 0.1%. I roto i nga hangahanga i Haina, kua eke te onepu whakamaroke-whaiaro o te furan ki te taumata o te ao ahakoa te mahi whakaputa me te kounga o te mata o nga whakarewanga.
Ko te rino whakarewa, e kiia ana hoki ko te rino nodular, te rino graphite spheriodal, te rino SG noa ranei mo te poto, e tohu ana i te roopu rino. Nodular maka rino whiwhi graphite nodular i spheroidization me te inoculation maimoatanga, e pai te whakapai ake i te āhuatanga pūkaha o te rino maka, rawa te kirihou me te uaua, kia rite ki te whiwhi kaha teitei atu i te waro maitai.
He pai ake te ruinga o te whakarewanga rino i te waro maitai, engari he pai ake te pai o te weldability o te whakarewanga waro. A, i etahi waahanga, ka taea e nga whakarewanga rino ngongo etahi mahi o te mau kakahu me te waikura. Na ka taea te whakamahi i te whakarewa rino mo etahi whare papua, he punaha tuku wai ranei. Heoi ano, me kaha tonu tatou ki te tiaki kia kore e mau me te waikura.
Ko te rino ductile ehara i te mea kotahi engari he wahanga o te roopu o nga rawa ka taea te whakaputa kia maha nga momo taonga ma te whakahaere i te hanganga moroiti. Ko te ahuatanga o tenei roopu rawa ko te ahua o te kauwhata. I roto i nga rino ductile, ko te kauwhata kei roto i te ahua o te nodules kaua ki te tawerewere i te mea kei roto i te rino hina. Ko te ahua koi o nga tawerewere o te kauwhata ka waihanga i nga tohu kukū i roto i te matrix whakarewa me te ahua porotaka o nga nodules iti iho, na reira ka aukati i te hanga kapiti me te whakakaha ake i te ductility e whakaingoa ai te koranu. Ko te tikanga, mena ka taea e te rino ngongo te whakatutuki i o hiahia, ko te rino ductile te mea tuatahi hei whiriwhiri maau, hei utu mo te rino waro mo o whakarewanga.

Ko nga Painga o te Furan Resin pania kirikiri-whakapakeke-whakapakeke-whakaekea te Maka:
1) Whakapai ake i te tika o te ahu o te whakarewanga me te taratara o te mata.
2) Ko te whakamaroke o te kirikiri (matua) kaore e hiahiatia kia whakamaroke, ka taea te whakaora i te kaha, ka taea hoki te whakamahi i nga pouaka rakau iti, kirihou ranei me nga tauira.
3) Ko te kirikiri whakapakeke-whaiaro he ngawari ki te taapiri me te pakaru, ngawari ki te horoi i nga whakarewa, ka taea te hangarua i te kirikiri tawhito me te whakamahi ano, ka tino whakaitihia te kaha o te mahi o te hanga matua, te whakatauira, te taka o te onepu, te horoi me etahi atu hononga, me he ngawari ki te mohio ki te miihini, ki te miihini ranei.
4) Ko te hautanga papatipu o te kapia i roto i te onepu ko te 0.8%~2.0% anake, a he iti te utu matawhānui o nga rauemi mata.
Na te mea he maha nga painga ahurei kua whakahuahia ake nei e te tikanga whakapakeke-whaiaro, kaore i te whakamahia te tikanga whakapakeke-whaiaro mo te hanga matua, engari ka whakamahia ano hoki mo te whakarewanga whakarewa. He tino pai mo te waahanga kotahi me te hanga puranga iti, a ka taea te whakaputa i te rino, te whakarewa maitai me te whakarewa kore-ferrous. Ko etahi o nga whare hangahanga Hainamana kua whakakapi katoa i te uku kirikiri kirikiri maroke, kirikiri kirikiri sima, me etahi waahanga whakakapinga mo te kirikiri karaihe wai.
