Foundry Ceramic Sand
Features
• Kuumbwa kwechikamu chakafanana
• Yakagadzika saizi yezviyo kugovera uye kufema kwemhepo
• High refractoriness (1825°C)
• Kurwisana kwepamusoro kupfeka, kupwanya uye kupisa kwekushisa
• Kuwedzera kuduku kwemafuta
• Kunyorova kwemvura kwakanakisa uye kushanda zvakanaka kwekuzadza nekuda kwekutenderera
• Yakanyanya kudzoreredza mwero mujecha loop system
Kushandisa Sand Foundry Maitiro
RCS (Resin yakavharwa jecha)
Cold box sand process
3D kudhinda jecha maitiro (Batanidza Furan resin uye PDB Phenolic resin)
Kwete-kubheka resin jecha maitiro (Batanidza Furan resin uye Alkali phenolic resin)
Investment process/ Yakarasika wax foundry process/ Precision casting
Yakarasika uremu maitiro/ Yarasika furo maitiro
Mvura yegirazi nzira
Tsanangudzo
Foundry Ceramic Sand - mhinduro yakakwana kune zvese zvaunoda. Ichi chigadzirwa chitsva chinonziwo ceramsite, cerabeads, kana ceramcast, uye chinogadzirwa kubva kucalcined bauxite ichichipa yakanakisa spherical tsanga chimiro. Iine yakakwirira yealuminium oxide uye silicon oxide, Ceramic Sand inozvikudza zvivakwa zvichienzaniswa neyakajairwa silica jecha.
Ceramic Sand inopa akawanda mabhenefiti pane silica jecha. Chekutanga, ine yakakwira zvakanyanya refractoriness, ichiita kuti ive yakakodzera kushandiswa mukupisa-kupisa kwekushandisa. Iyo ine zvakare yakaderera kupisa kwekuwedzera, kuve nechokwadi kuti inochengetedza jecha mold kana musimboti chimiro uye kuenderana kunyangwe panguva yekupisa kwakanyanya.
Pamusoro pesimba rayo rinokatyamadza, Ceramic Sand inopa yakanakisa kuyerera - izvi zvinovimbisa kuti inogona kuumbwa nyore uye kuumbwa panguva yekukanda maitiro. Uyezve, Ceramic Sand ine yakakwirira kuramba kupfeka, kupwanya, uye kuvhunduka kwemafuta, zvichiita kuti ive sarudzo yakanaka kune ese marudzi ekukanda maapplication.
Imwe yakakosha mukana wekushandisa Foundry Ceramic Sand ndeyekuti ine yakakwira reclamation rate, zvichireva kuti inogona kushandiswa zvakare nyore mukukanda maitiro. Izvi, zvakare, zvinobatsira kuderedza marara uye kuderedza mari.
Pakazere, Foundry Ceramic Sand ndiyo inofanirwa-kuve nayo kune chero inowanikwa inotarisa kuvandudza mashandiro avo ekukanda. Nezvayo zvakanakisa zvivakwa uye simba repamusoro, inopa yakakosha mukana pane yechinyakare silica jecha.
