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.
Mchanga kamili wa kauri hutumiwa kutengeneza mchanga uliofunikwa, na kutumika tena mara kwa mara baada ya kutengenezwa tena, ambayo inaweza kuboresha ubora na ufanisi wa uzalishaji wa castings, kupunguza kiwango cha uwekaji chapa na gharama ya uzalishaji wa biashara, gharama ya matumizi ya muda mrefu ni ya chini kuliko hiyo. mchanga wa silika. Kwa hivyo, katika miaka ya hivi karibuni, karibu mimea yote ya mchanga iliyofunikwa kwa kiwango kikubwa imetumia mchanga wa kauri kama mchanga mbichi kutoa mchanga uliofunikwa.
Faida
● Resin iliyotiwa mchanga wa kauri na upinzani wa joto la juu, upinzani mkali kwa kiwango cha deformation, mfumuko wa bei ya chini, mageuzi ya chini ya gesi, ili kukidhi mahitaji maalum ya wateja.
● Uwezo mzuri wa kujaza maji, ukungu usio na fimbo, unaotumika kwa mchakato wa kutengeneza msingi bandia.
● Ustahimilivu wa halijoto ya juu sana unaweza kuepukwa na kasoro za kutupa kama vile kuungua kwa mchanga, kukunja uso, mshipa, mweko wa viungo na ufa.
● Small than 100kg castings could be achieved without sand coating.
