Kujambula kwa zipolopolondondomeko amatchedwanso pre- TACHIMATA utomoni mchenga kuponya ndondomeko, otentha chipolopolo akamaumba castings kapena pachimake kuponyera ndondomeko. Zomwe zimapangidwira kwambiri ndi mchenga wa phenolic resin wophimbidwa kale, womwe ndi wokwera mtengo kuposa mchenga wobiriwira ndi mchenga wa furan resin. Komanso, mchenga sungagwiritsidwenso ntchito.
Njira yopangira mchenga wowumitsa utomoni wa Furan (ndondomeko ya nobake) imagwiritsa ntchito mchenga wokutidwa ndi furan kupanga nkhungu. Pambuyo kusakaniza mchenga wapachiyambi (kapena mchenga wobwezeretsedwa), utomoni wamadzimadzi wa furan ndi chothandizira chamadzimadzi mofanana, ndikuwadzaza mu bokosi lalikulu (kapena mchenga), ndiyeno mumangirire kuti muwumitse mu nkhungu kapena nkhungu mu bokosi lalikulu (kapena mchenga). box) pa kutentha. Ndiye kuponya nkhungu kapena kuponyera pachimake anapangidwa, amene amatchedwa kudziletsa kuumitsa ozizira pachimake bokosi akamaumba (pachimake), kapena kudziletsa kuumitsa njira (pachimake).
Chifukwa nkhungu imapangidwa pa kutentha kwa chipinda ndipo palibe chifukwa chotenthetsa, kuponyera mchenga wodziumitsa kumatchedwanso kuti palibe-bake casting process. Njira yodziumitsa yokha imatha kugawidwa mu acid-catalyzed furan resin ndi phenolic resin mchenga kudziletsa njira, urethane resin mchenga kudziletsa kuumitsa njira ndi phenolic monoester kudziletsa kuumitsa njira.
Monga mchenga wodziumitsa wowumitsa, mchenga wa furan resin ndiye mchenga wakale kwambiri komanso womwe amagwiritsidwa ntchito kwambiri pakupanga mchenga ku China. Kuchuluka kwa utomoni wowonjezeredwa mumchenga wowumba nthawi zambiri kumakhala 0.7% mpaka 1.0%, ndipo kuchuluka kwa utomoni wowonjezera mumchenga wapakati nthawi zambiri kumakhala 0.9% mpaka 1.1%. Zomwe zili mu aldehyde yaulere mu furan resin ndizochepera 0.3%, ndipo mafakitale ena atsikira pansi pa 0.1%. M'malo oyambira ku China, mchenga wowumitsa utomoni wa furan wafika pamlingo wapadziko lonse lapansi mosasamala kanthu za njira yopangira komanso mawonekedwe apamwamba a castings.

Ubwino wa Furan Resin Wokutidwa ndi Mchenga Wodzilimbitsa Moumitsa Wodzipangira:
1) Sinthani kulondola kwa mawonekedwe a castings ndi roughness pamwamba.
2) Kuuma kwa nkhungu (pachimake) mchenga sikufuna kuyanika, komwe kungapulumutse mphamvu, komanso matabwa otsika mtengo kapena mabokosi apulasitiki ndi ma templates angagwiritsidwenso ntchito.
3) Mchenga wodzilimbitsa wokhawokha ndi wosavuta kuphatikizika ndikugwa, zosavuta kuyeretsa zotayira, ndipo mchenga wakale ukhoza kubwezeredwa ndikugwiritsanso ntchito, zomwe zimachepetsa kwambiri kulimba kwa ntchito yopanga pachimake, kufananiza, kugwa kwa mchenga, kuyeretsa ndi maulalo ena, ndi ndikosavuta kuzindikira makina kapena makina.
4) Gawo lalikulu la utomoni mumchenga ndi 0.8% ~ 2.0% yokha, ndipo mtengo wathunthu wazopangira ndizotsika.
Chifukwa chakuti njira yodzipangira yokha ili ndi ubwino wambiri womwe watchulidwa pamwambapa, njira yodzipangira yokha siigwiritsidwa ntchito popanga pachimake, komanso imagwiritsidwa ntchito popanga kuumba. Ndizoyenera kwambiri kupanga chidutswa chimodzi ndi kupanga batch yaying'ono, ndipo zimatha kupanga chitsulo choponyedwa, chitsulo choponyedwa ndi alloy castings. Malo ena opangira zinthu ku China alowa m'malo mwa nkhungu za mchenga wouma, zoumba za mchenga wa simenti, ndikusintha pang'ono za mchenga wa magalasi amadzi.
