Ceramic sand properties

Ceramic foundry jecha, rakatumidzwawo seceramsite, cerabeads, yakanaka yekugadzira bhora jecha foundries.Enzanisa nejecha reSilica, ine yakakwira refractoriness, kuwedzera kudiki kwemafuta, yakanaka angular coefficient, yakanakisa kuyerera, yakakwira kuramba kupfeka, yakakwirira reclamation rate, inogona kuderedza resin yekuwedzera uye coating, kuwedzera yako castings goho.

● Yakagadzika saizi yezviyo kugovera uye kufema kwemhepo

● High refractoriness (>1800°C)

● Kurwisana kwepamusoro kupfeka, kupwanya uye kupisa kwekushisa

● High reclamation rate

● High collapsibility.

● Kuwedzera kuduku kwemafuta

● Kuyerera kwakanakisa uye kushanda zvakanaka kwekuzadza nekuda kwekutenderera
