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.
Mchenga wa ceramic wathunthu umagwiritsidwa ntchito popanga mchenga wokutidwa, ndipo umagwiritsidwanso ntchito mobwerezabwereza pambuyo pokonzanso, zomwe zimatha kuwongolera bwino komanso kupanga bwino kwa ma castings, kuchepetsa kuchuluka kwa castings scrape ndi mtengo wopanga mabizinesi, kugwiritsa ntchito nthawi yayitali ndikotsika kuposa komweko. mchenga wa silika. Choncho, m'zaka zaposachedwa, pafupifupi zomera zonse zazikulu zamchenga zakhala zikugwiritsa ntchito mchenga wa ceramic ngati mchenga waiwisi kupanga mchenga wokutidwa.
Ubwino
● utomoni wokutira mchenga ceramic ndi wapamwamba kukana kutentha, kukana mwamphamvu mapindikidwe mwamphamvu, otsika inflation, otsika kusanduka gasi, kukwaniritsa zofunika makasitomala.
● Kukhoza bwino kudzaza madzimadzi, nkhungu yopanda ndodo, yogwiritsidwa ntchito popanga maziko opangira.
● Kutentha kwapamwamba kwambiri kungapewere kuwonongeka kwa mchenga monga kuwotcha mchenga, kupindika pamwamba, mitsempha, kung'anima kwa mafupa ndi ming'alu.
● Small than 100kg castings could be achieved without sand coating.
