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.
Defnyddir tywod ceramig llawn i wneud tywod wedi'i orchuddio, a'i ailddefnyddio dro ar ôl tro ar ôl ei adennill, a all wella ansawdd ac effeithlonrwydd cynhyrchu castiau yn effeithiol, lleihau cyfradd sgrapio castiau a chost cynhyrchu mentrau, mae'r gost defnydd hirdymor yn is na hynny o dywod silica. Felly, yn ystod y blynyddoedd diwethaf, mae bron pob planhigyn tywod wedi'i orchuddio ar raddfa fawr wedi defnyddio tywod ceramig fel tywod amrwd i gynhyrchu tywod wedi'i orchuddio.
Mantais
● Tywod ceramig wedi'i orchuddio â resin gydag ymwrthedd tymheredd uchel iawn, ymwrthedd cryf i ddwysedd anffurfio, chwyddiant isel, esblygiad nwy isel, i fodloni gofynion arbennig cwsmeriaid.
● Gallu llenwi hylifedd da, llwydni nad yw'n glynu, sy'n berthnasol ar gyfer y broses gwneud craidd artiffisial.
● Gallai ymwrthedd tymheredd uchel super osgoi castio diffygion fel llosgi tywod, plygu arwyneb, gwythiennau, fflachio ar y cyd a chrac.
● Small than 100kg castings could be achieved without sand coating.
