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.
Ciidda dhoobada buuxa waxaa loo isticmaalaa in lagu sameeyo ciid dahaarka leh, oo dib loo isticmaalo si isdaba joog ah ka dib dib-u-soo-celinta, taas oo si wax ku ool ah u wanaajin karta tayada iyo wax-soo-saarka wax-soo-saarka, hoos u dhigista xajinta xajmiga iyo qiimaha wax soo saarka shirkadaha, kharashka isticmaalka muddada-dheer ayaa ka hooseeya taas. oo ciid silica ah. Sidaa darteed, sannadihii la soo dhaafay, ku dhawaad dhammaan dhirta ciidda dahaarka leh ee baaxadda weyn waxay isticmaaleen ciidda dhoobada sida ciid ceeriin si ay u soo saaraan ciid daboolan.
Faa'iidada
● Ciidda dhoobada dahaarka leh ee resin oo leh iska caabin heerkul sare ah, iska caabin xooggan u leh xoojinta qallafsanaanta, sicir-bararka hooseeya, kobcinta gaaska hooseeya, si loo buuxiyo shuruudaha gaarka ah ee macaamiisha.
● Awoodda buuxinta dheecaanka wanaagsan, caaryada aan dhegta lahayn, ee lagu dabaqi karo habka aasaasiga ah ee samaynta.
● Iska caabbinta heerkulka sare ee sarreeya waxay ka fogaan kartaa inay tuurto cilladaha sida gubashada ciidda, laalaabka dusha sare, xididdada, fallaadhaha wadajirka ah iyo dildilaaca.
● Small than 100kg castings could be achieved without sand coating.
