Kev piav qhia
Ceramsite Sand, cov khoom lag luam hloov pauv uas tau hloov pauv kev lag luam hauv kev lag luam. Ua los ntawm cov khoom zoo calcined bauxite, lub pob dub zoo li cov xuab zeb no tau tsim los muab kev ua tau zoo tshaj plaws hauv kev molding thiab core sand applications.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm Ceramsite Sand yog nws yuav luag zoo kawg nkaus kheej kheej. Cov duab tshwj xeeb no tsim cov yam ntxwv zoo heev thiab cov pa permeation, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ob qho tib si pwm thiab cov tub ntxhais ntau lawm. Qhov tseeb, cov ntaub ntawv khaws cia txog li 50% tau ua tiav piv rau lwm cov xuab zeb, tsis muaj kev poob hauv cov tub ntxhais lub zog.
Ntxiv nrog rau nws cov molding superior thiab cov ntsiab lus xuab zeb, Ceramsite Sand rau kev siv cov khoom siv kuj tseem muab qhov zoo tshaj plaws nto tiav ntawm castings. Qhov no, ua ke nrog nws cov refractoriness siab (1800 ° C) thiab tsis kam hnav, tsoo thiab thermal shock, ua rau nws mus rau kev xaiv rau ntau hom kev siv hauv tsev.
Tab sis tsis yog tag nrho - Ceramsite Sand kuj boasts ib tug ruaj khov grain loj faib thiab huab cua permeability, ua ke nrog me ntsis thermal expansion. Qhov no ua kom ntseeg tau tias cov xuab zeb tseem nyob hauv qhov sib xyaw ua ke, thiab muab cov dej ntws zoo heev thiab kev ua haujlwm puv.
Thiab, nrog lub siab tshaj plaws reclamation tus nqi nyob rau hauv cov xuab zeb voj system, Ceramsite Sand tsis yog tsuas zoo tab sis kuj ib puag ncig muaj kev ruaj ntseg. Nws tuaj yeem siv dua thiab rov ua dua, ua rau muaj txiaj ntsig zoo rau cov khoom lag luam hauv lub sijhawm.
Hauv kev xaus, Ceramsite Sand yog qhov hloov pauv kev ua si hauv kev lag luam foundry. Nws cov khoom tshwj xeeb thiab kev ua tau zoo tshaj plaws tau hloov pauv txoj hauv kev tsim cov khoom lag luam, thiab nws tseem yog qhov kev xaiv zoo tshaj plaws rau cov chaw tsim khoom thoob ntiaj teb. Sim nws rau koj tus kheej thiab paub txog cov txiaj ntsig ntawm Ceramsite Sand, qhov kawg ntawm cov xuab zeb tov!
