Ceramic Foundry Sand

Kufotokozera Kwachidule:

Al2O3-based Ceramic foundry mchenga ndi mchenga wopangidwa wokhala ndi refractoriness yayikulu ya 1800 °C. Mchenga wa Ceramic foundry umagwiritsidwa ntchito kwambiri m'makampani opanga zinthu monga kuumba komanso mchenga wapakati chifukwa cha mawonekedwe ake ozungulira, omwe amapereka mphamvu zoyenda bwino komanso kutulutsa mpweya. Popanda kupereka mphamvu yayikulu, ndizotheka kusunga mpaka 50% pa binder pakupanga pachimake poyerekeza ndi mchenga wina. Nthawi yomweyo, zopangira zopangidwa ndi mchenga wa Ceramic wazoyambira zimakhala ndi zomaliza zapadera.

Tsatanetsatane wa Zamalonda

Zolemba Zamalonda

Mawonekedwe

• Chigawo cha yunifolomu
• Kugawa kwakukula kwambewu yokhazikika komanso kuthekera kwa mpweya
• Kukana kwambiri (1825°C)
• Kukana kwambiri kuvala, kuphwanya ndi kutenthedwa kwa kutentha
• Kuwonjezeka pang'ono kwa kutentha
• Kuchuluka kwamadzimadzi komanso kudzaza bwino chifukwa chokhala ozungulira
• Mlingo wapamwamba kwambiri wobwezeretsanso mumchenga wa loop system

Kugwiritsa Ntchito Sand Foundry Njira

Njira ya mchenga yokutidwa ndi utomoni
Cold bokosi ndi ofunda bokosi mchenga ndondomeko
3D mchenga kusindikiza ndondomeko
Njira ya mchenga wosaphika (Phatikizanipo utomoni wa Furan ndi Alkali phenolic resin)
Njira yopangira ndalama / Kutayika kwa sera yotayika / Kuponyera mwatsatanetsatane
Njira yotaya kulemera / Kutaya thovu
Madzi galasi ndondomeko
