Chinese Ceramic Beads for RCS Application

Kufotokozera Kwachidule:

Mikanda ya Ceramic, yomwe imatchedwanso cerabeads, mchenga wa ceramic, ceramcast, ndi mawonekedwe abwino opangira njere ozungulira omwe amapangidwa kuchokera ku calcined bauxite.Zomwe zili mkati mwake ndi aluminium oxide ndi Silicon oxide.Yogwiritsidwa ntchito mu njira ya RCS, imakhala ndi kukana kutentha kwambiri, kukulitsa pang'ono, kugwa kosavuta, komanso kutulutsa mpweya wochepa, womwe ungalepheretse kuwonongeka kwakukula kwa castings.Kwa ma cores omwe ali ndi mawonekedwe ovuta kwambiri, amatha kuthana ndi vuto lomwe kuwombera mchenga sikophweka kuphatikizika.

Pakadali pano, chifukwa cha katundu wake wozungulira, imachepetsa kuwonjezera kwa utomoni ndikuponya bwino komanso kutsika mtengo.

Mawonekedwe

• Chigawo cha yunifolomu
• Kugawa kwakukula kwambewu yokhazikika komanso kuthekera kwa mpweya
• Kukana kwambiri (1800°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

Mikanda ya Ceramic yaku China ya RCS Application2

Kugwiritsa Ntchito Sand Foundry Njira

RCS (mchenga wokutidwa ndi resin)
Cold box mchenga ndondomeko
3D kusindikiza mchenga ndondomeko (Phatikizani Furan utomoni ndi PDB Phenolic utomoni)
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
