Ceramic foundry jecha regirini jecha maitiro
Green Sand Castings zviumbwa zvinogadzirwa nejecha rakanyorova kana "jecha regirinhi".Jecha racho harina ruvara rwegirinhi uyewo zviumbwa hazvishandisi “jecha regirinhi,” jecha rine ruvara rwegirinhi.Panzvimbo pejecha rinonzi "girinhi" nokuti rine hunyoro mukati maro (sehuni yakasvibirira) jecha risati raoma kana simbi yakanyungudutswa ichidirwa muforoma.
Chinopa jecha kunyorova uye chinobatsira jecha kunamatirana pakugadzira moumbwe ivhu rinosanganiswa mujecha.Bentonite ivhu uye jecha rakavhenganiswa pamwe chete rinopa zviumbwa zvakasimba zvinogona kugadzirwa pamutsetse wegungano.
Sintered ceramic foundry jecha rinonyanya kugadzirwa nemaminerari ane Al2O3 uye SiO2 uye anowedzerwa nezvimwe zvicherwa zvinhu.A spherical foundry jecha rakagadzirwa nehupfu, pelletizing, sintering uye grading maitiro.Yayo huru yekristaro chimiro ndeye Mullite uye Corundum, ine yakatenderedzwa zviyo chimiro, yakakwirira refractoriness, yakanaka thermochemical kugadzikana, kuderera kwekuwedzera kwemafuta, kukanganisa uye abrasion kuramba, zvimiro zvekutsemuka kwakasimba.Kana jecha receramic rinoshandiswa mukugadzira jecha rakasvibirira, rinogona kuwedzera jecha rakasvibira rakashandiswazve nguva, kuderedza tsvina yejecha kubudiswa, nekuvandudza goho rekukanda.
Advantage
● Super tembiricha kuramba uye zvakanakisa kufema kunoita yakakwira mechanical reclamation mwero wejecha, yakaderera tsvina jecha kubudiswa.
● Kupinza kwepamusoro.Kupinda kwejecha regirinhi rakasanganiswa nejecha rekukanda sintered ceramic raive rakakwira kupfuura iro rakasanganiswa nejecha requartz pasi pemamiriro akafanana.
Zvikamu zveParticle size Distribution
Iyo particle size yekugovera inogona kugadzirwa zvinoenderana nezvaunoda.
