Ceramsite sand is an artificial spherical casting sand developed by SHXK, same with Japanese Cerabeads. It has high refractoriness (>1800°C), small angular coefficient (<1.1, approximately spherical), low acid consumption (neutral material), low binder content (at least 30% reduction in binder content), and particles high strength, non-breaking and other excellent characteristics, suitable for all types of sand foundry, especially for the coated sand. There are more successful application cases.
Folsleine keramyske sân wurdt brûkt foar it meitsjen fan coated sân, en werbrûkt ferskate kearen nei reclamation, dat kin effektyf ferbetterje de kwaliteit en produksje effisjinsje fan castings, ferminderjen de castings scrape rate en de produksje kosten fan bedriuwen, de lange-termyn gebrûk kosten is leger dan dat fan silika sân. Dêrom hawwe yn 'e ôfrûne jierren hast alle grutskalige bedekte sânplanten keramysk sân brûkt as rau sân om bedekt sân te meitsjen.
Foardiel
● Resin coated keramyske sân mei super hege temperatuer ferset, sterke ferset tsjin deformation yntinsiteit, lege ynflaasje, lege gas evolúsje, te foldwaan oan de spesjale easken fan klanten.
● Goede fluidity filling fermogen, non-stick skimmel, fan tapassing foar it keunstmjittige kearnmakke proses.
● Super hege temperatuer ferset koe mije oan casting mankeminten lykas sân baarnende, oerflak fold, veining, joint flash en crack.
● Small than 100kg castings could be achieved without sand coating.
