Kev piav qhia
Super Ceramic Sand yog ib tug neeg tsim kheej kheej particle zoo li high-end foundry xuab zeb.Paub los ntawm ntau lub npe suav nrog Ceramic Sand, Cerabeads thiab CeramCast, qhov kev xaiv zoo tshaj plaws rau kev lag luam xuab zeb.
Ib qho ntawm qhov zoo tshaj plaws ntawm super ceramic xuab zeb yog nws cov refractoriness siab.Tsis tas li ntawd, cov khoom lag luam yuav luag tsis muaj thermal expansion, uas txhais tau hais tias nws khaws nws cov duab txawm tias muaj kev hloov pauv ntawm qhov kub thiab txias.
Super Ceramic Sand kuj muaj lub kaum sab xis zoo, uas txhais tau hais tias nws ntws tawm ntawm cov duab nyuaj thiab cov ntsiab lus sib txawv.Qhov no ua rau nws zoo tagnrho rau complex castings thiab pwm.
Lwm qhov ua tau zoo ntawm Super Ceramic Sand yog nws tus nqi rov qab siab.Qhov no txhais tau hais tias cov khoom tuaj yeem rov qab siv tau ntau zaus, uas tsis yog tsuas yog txo cov khoom pov tseg, tab sis kuj txuag lub sijhawm thiab nyiaj txiag.Tus nqi rov qab siab kuj txhais tau tias cov khoom yog ib puag ncig tus phooj ywg vim nws txo qis cov khoom siv uas yuav tsum tau mined thiab ua tiav.
Hauv kev xaus, Super Ceramic Sand yog qhov hloov pauv kev ua si rau kev lag luam xuab zeb.Nrog nws cov kev ua tau zoo thiab kev ua haujlwm tshwj xeeb, nws yog qhov zoo tagnrho rau cov txheej txheem castings thiab pwm.Nws cov nqi rov ua dua siab dua thiab cov txiaj ntsig ib puag ncig ua rau nws muaj lub luag haujlwm thiab kev xaiv ruaj khov rau cov tuam ntxhab.
