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.
To'liq keramik qum qoplangan qumni tayyorlash uchun ishlatiladi va melioratsiyadan keyin qayta-qayta ishlatiladi, bu quymalarning sifati va ishlab chiqarish samaradorligini samarali oshirishi, to'qimalarning qirqish tezligini va korxonalarning ishlab chiqarish xarajatlarini kamaytirishi mumkin, uzoq muddatli foydalanish narxi undan past. silika qumidan. Shu sababli, so'nggi yillarda deyarli barcha yirik qoplamali qum zavodlari qoplangan qum ishlab chiqarish uchun xom qum sifatida keramik qumdan foydalangan.
Afzallik
● Mijozlarning maxsus talablarini qondirish uchun super yuqori haroratga chidamlilik, deformatsiya intensivligiga kuchli qarshilik, past inflyatsiya, past gaz evolyutsiyasi bilan qatron bilan qoplangan keramik qum.
● Yaxshi suyuqlikni to'ldirish qobiliyati, yopishmaydigan qolip, sun'iy yadro yaratish jarayoni uchun qo'llaniladi.
● Yuqori haroratga chidamlilik qumning yonishi, sirt burmalari, tomirlar, bo'g'inlar chirog'i va yorilish kabi quyma nuqsonlardan qochishi mumkin.
● Small than 100kg castings could be achieved without sand coating.
