Zvinoenderana nekuverenga uye manhamba, iyo ceramic sand shell casting process inoda avhareji ye0.6-1 matani ejecha rakavharwa (musimboti) kuburitsa 1 toni yekukanda. Nenzira iyi, kurapwa kwejecha rakashandiswa rave iro rinonyanya kukosha mukuita uku. Izvi hazvisi izvo chete kudikanwa kwekudzikisa mutengo wekugadzira nekuvandudza mabhenefiti ehupfumi, asiwo kudikanwa kwekudzikisa kusvibiswa kwemarara, kuziva hupfumi hwakatenderedza, kurarama mukuwirirana nemhoteredzo, uye kuwana budiriro inoenderera.
Chinangwa chekudzorerazve jecha receramic rakavharidzirwa ndechokubvisa firimu resin rakasara rakaputirwa pamusoro pezviyo zvejecha, uye panguva imwechete kubvisa simbi yakasara uye mamwe matsvina mujecha rekare. Izvi zvakasara zvinokanganisa zvakanyanya kusimba uye kuoma kwejecha receramic rakavharwa rakadzoserwa, uye panguva imwechete kuwedzera huwandu hwekugadzirwa kwegasi uye mukana wekugadzira tsvina. Izvo zvinodiwa zvehutano zvejecha rakadzorerwa zvinowanzo: kurasikirwa pamoto (LOI) <0.3% (kana chizvarwa chegesi <0.5ml / g), uye kushanda kwejecha rakadzorerwa rinosangana neindekisi iyi mushure mekuputira haisi yakasiyana zvikuru nejecha idzva.
Ijecha rakavharidzirwa rinoshandisa thermoplastic phenolic resin sebinder, uye firimu rayo resin rakaoma. Mune dzidziso, zvese zvinopisa uye zvemuchina nzira dzinogona kubvisa yakasara resin firimu. Thermal regeneration inoshandisa nzira ye carbonization ye resin film pahupamhi hwekushisa, iyo ndiyo nzira yakakwana uye inoshanda yekuvandudza.
Nezve thermal reclamation process yecoated ceramic jecha, masangano ekutsvagisa uye vamwe vagadziri vakaita nhamba huru yezvidzidzo zvekuyedza. Parizvino, nzira inotevera inowanzo shandiswa. Tembiricha yechoto yekugocha i700°C-750°C, uye tembiricha yejecha i650°C-700°C. Iyo nzira yekudzorerazve ndeye:
(Kuzunguzika) →magnetic separator → tsvina yejecha preheating → (mugomo wemugomo) → (sikuru yekudyira) → yadzoreredzwa jecha rekuchengetera hovha → feni inofashaidza → mubhedha unotonhodza →huvhu yekubvisa guruva kutakura jecha tsvina → choto chekugocha chine fluidized → bhaketi rejecha repakati → mutsara wekugadzira jecha wakavharidzirwa
Nezve ceramic jecha reclamation midziyo ine chekuita, thermal reclamation inowanzo shandiswa. Masosi emagetsi anosanganisira magetsi, gasi, marasha (coke), biomass mafuta, nezvimwewo, uye nzira dzekutsinhana kupisa dzinosanganisira rudzi rwekusangana uye rudzi rwekuvira kwemhepo. Pamusoro pemamwe makambani makuru anozivikanwa ane midziyo yekudzokorodza yakatokura, makambani madiki mazhinji ane midziyo yakawanda yeungwaru yekudzokorodza yakavakwa ega.
