Qum quyish quyish uchun oltin qum

Qisqa Tasvir:

Quyma seramika qumi, texnik jihatdan "Quyma uchun sinterlangan keramik qum" deb nomlanadi, shuningdek, keramika, keramika, keramika bilan bir xil, ba'zi mamlakatlarda Oltin qum deb ham ataladi, kalsinlangan boksitdan tayyorlangan yaxshi sun'iy sharsimon don shaklidir. Uning asosiy tarkibi alyuminiy oksidi va kremniy oksididir. Seramika qum, quyishda yaxshiroq ishlash uchun silika qumiga qaraganda ancha yaxshi xususiyatlarga ega. U yuqori refrakterlik, kichik termal kengayish, yaxshi burchak koeffitsienti, mukammal oquvchanlik, aşınmaya, ezish va termal zarbalarga yuqori qarshilik, yuqori melioratsiya darajasiga ega.

Mahsulot detali

Mahsulot teglari

Foundry Ceramic Sand, technically named as “Sintered Ceramic Sand for Foundry”, also named as ceramsite, cerabeads, ceramcast, some countries is also named Golden Sand, is good artificial spherical grain shape which is made from calcined bauxite . Its main content is aluminum oxide and Silicon oxide. Ceramic sand, has much better properties than that of silica sand to gain a better performance in foundry. It has high refractoriness, little thermal expansion, good angular coefficient, excellent flowability, High resistance to wear, crush and thermal shock, high reclamation rate.

Afzallik

Kaist ceramic foundry sand is about half as light as zircon and chromite, is about third as light as fused ceramic sand. Compared to these natural sand and other foundry media (the material is able to turn out about twice the number of molds per unit weight). Kaist ceramic foundry sand can deliver mold and core packages with a range of benefits that include higher-strength sand casting packages, with high heat resistance, low thermal expansion, improved final part resolution and a smoother surface finish. It can also be handled very easily, saving labor and transfer power costs. However, the manufacturer recommends paying attention to the amount of binder addition.

Ilova

Neytral material sifatida KAIST seramika qumi kislota va gidroksidi qatronlar uchun qo'llaniladi.

U quyma temir, quyma po'lat va rangli metallarni quyish uchun keng qo'llanilishi mumkin, masalan, yo'qolgan ko'pikli quyma, qoplangan qum, qatron qumi, sovuq yadro qutisi, nozik quyma va 3D bosib chiqarish.
