Kev piav qhia
Foundry Ceramic Sand - qhov kev daws teeb meem zoo tshaj plaws rau tag nrho koj cov kev xav tau ntawm qhov chaw tsim khoom. Cov khoom tshiab no tseem hu ua ceramsite, cerabeads, lossis ceramcast, thiab yog tsim los ntawm calcined bauxite muab nws zoo heev spherical grain zoo. Nrog nws cov ntsiab lus siab ntawm aluminium oxide thiab silicon oxide, Ceramic Sand boasts superior zog piv rau cov pa silica xuab zeb.
Ceramic Sand muaj ntau yam zoo dua silica xuab zeb. Ua ntej, nws muaj ntau dua refractoriness, ua rau nws zoo tagnrho rau siv nyob rau hauv high-temperature daim ntaub ntawv. Nws kuj muaj qhov tsis tshua muaj thermal expansion, kom ntseeg tau tias nws tuav cov xuab zeb pwm lossis cov tub ntxhais zoo li qub thiab sib xws txawm tias thaum tshav kub kub heev.
Ntxiv rau nws lub zog zoo kawg nkaus, Ceramic Sand muaj cov dej ntws zoo heev - qhov no ua kom nws tuaj yeem yooj yim molded thiab zoo li tus thaum lub sij hawm casting txheej txheem. Tsis tas li ntawd, Ceramic Sand muaj kev tiv thaiv siab hnav, tsoo, thiab thermal shock, ua rau nws qhov kev xaiv zoo tshaj plaws rau txhua yam kev siv casting.
Lwm qhov txiaj ntsig tseem ceeb ntawm kev siv Foundry Ceramic Sand yog tias nws muaj tus nqi rov qab siab, txhais tau tias nws tuaj yeem rov qab siv tau yooj yim hauv txheej txheem casting. Qhov no, nyob rau hauv lem, yuav pab txo cov khib nyiab thiab txo cov nqi.
Zuag qhia tag nrho, Foundry Ceramic Sand yog qhov yuav tsum muaj rau txhua qhov chaw nrhiav los txhim kho lawv cov kev ua tau zoo. Nrog nws cov khoom zoo heev thiab lub zog zoo dua, nws muaj txiaj ntsig zoo dua li cov xuab zeb silica.
