Resin Wokutidwa ndi Ceramic Sand

Utomoni Wokutidwa ndi Ceramic Sand Chithunzi

Kufotokozera Kwachidule:

Mchenga wa ceramic umagwiritsidwa ntchito mu mchenga wowuma ndi mchenga wapakati kuti chipolopolo cha chipolopolo ndi chipolopolo cha chipolopolocho chikhale ndi mphamvu ya kukana kutentha kwambiri, kuwonjezereka kochepa, kugwa kosavuta, ndi kutuluka kwa mpweya wochepa, zomwe zingathe kuteteza kuwonongeka kwa kukula mu castings. Kwa ma cores omwe ali ndi mawonekedwe ovuta kwambiri, amatha kuthana ndi vuto lomwe kuwombera mchenga sikophweka kuphatikizika. Ndi mchenga wa ceramic womwe umagwiritsidwa ntchito mu RCS.

Mchenga wa ceramic wathunthu umagwiritsidwa ntchito popanga mchenga wokutidwa, ndipo umagwiritsidwanso ntchito mobwerezabwereza pambuyo pokonzanso, zomwe zimatha kuwongolera bwino komanso kupanga bwino kwa ma castings, kuchepetsa kuchuluka kwa castings scrape ndi mtengo wopanga mabizinesi, kugwiritsa ntchito nthawi yayitali ndikotsika kuposa komweko. mchenga wa silika. Choncho, m'zaka zaposachedwa, pafupifupi zomera zonse zazikulu zamchenga zakhala zikugwiritsa ntchito mchenga wa ceramic ngati mchenga waiwisi kupanga mchenga wokutidwa.

Mawonekedwe

• Kukana kwambiri—-kuponya zitsulo zotentha kwambiri (zitsulo zotayidwa, zitsulo zosapanga dzimbiri, zitsulo zosapanga dzimbiri, etc.)
• Mphamvu zazikulu ndi kulimba—–kuti apange ma cores ovuta kwambiri okhala ndi magawo oonda.
• Kuchepetsa kutentha kwa kutentha—–kupewa kuwonongeka kwa kukula.
• Zokolola zapamwamba zobwezeretsanso—-kuchepetsa kutaya mchenga, kuchepetsa ndalama.
• Kuyenda bwino kwambiri --kupanga ma cores ovuta.
• Kuchepetsa kugwiritsa ntchito binder--kutsika kwa gasi, kutsika mtengo wopangira.
• Makhalidwe a mankhwala osagwira ntchito--angagwiritsidwe ntchito muzitsulo zilizonse zotchuka, kuphatikizapo chitsulo cha Manganese.
• Nthawi yayitali yosungira.
