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.
Jecha rakazara receramic rinoshandiswa kugadzira jecha rakavharidzirwa, uye rinoshandiswazve kakawanda mushure mekugadzirisazve, izvo zvinogona kunyatso kuvandudza kunaka uye kugadzirwa kwemaitiro ekukanda, kuderedza castings scrape rate uye mutengo wekugadzira wemabhizinesi, mari yekushandiswa kwenguva refu yakaderera pane iyo. ye silica sand. Naizvozvo, mumakore achangopfuura, anenge ese mahombe akafukidzwa zvirimwa zvejecha zvakashandisa jecha receramic sejecha mbishi kugadzira jecha rakavharwa.
Advantage
● Resin yakavharwa nejecha receramic ine super high tembiricha kuramba, yakasimba kuramba deformation kusimba, yakaderera inflation, yakaderera gasi shanduko, kuzadzisa zvakakosha zvinodiwa vatengi.
● Yakanaka fluidity inozadza kugona, isina-tsvimbo mold, inoshanda kune yakagadzirwa core-making process.
● Super tembiricha inodzivirira inogona kudzivirira kukanda kuremara sekupisa jecha, kupetwa kwepamusoro, tsinga, kupenya kwemajoini uye kutsemuka.
● Small than 100kg castings could be achieved without sand coating.
Zvikamu zveParticle size Distribution
Iyo particle size yekugovera inogona kugadzirwa zvinoenderana nezvaunoda.

Application
Injini cylinder block, silinda musoro, piston mhete, mafuta chisimbiso, pasi chitubu.
Diki nepakati-stainless simbi, simbi yekukanda goko, off-core.
Used in large turbine shell mold, 6-8 speed gearbox, main part of auto brake disc,.
Muti-cylinder block (isina flip type core), iyo pombi yekuburitsa uye bronchus.
Camshaft, chisimbiso chemafuta, ganda rekona yekona.
Ese marudzi emhando yepamusoro, yakakwirira inodiwa, yakaoma maitiro eyakavharwa jecha castings.
