Versatile Ball Ball Bricks kanggo Insulation
Klasifikasi
Alumina hollow ball bricks & Zirconia hollow ball bricks
katrangan
Alumina kothong werni bricks digawe saka alumina kothong werni lan wêdakakêna alumina minangka bahan baku utama, digabungake karo Binder liyane, sawise 1750 derajat diperlokaké suhu dhuwur, belongs kanggo jenis suhu Ultra-dhuwur lan materi jampel hemat energi.
Fitur
Alumina kothong werni bricks ngemot nomer akeh ditutup porosity, mangkono wis kekuatan dhuwur lan stabilitas struktur porosity, Kapadhetan kurang, resistance kejut termal apik lan owah-owahan cilik saka linear permanen, konduktivitas termal kurang.
Zirconia kothong werni bricks karo resistance suhu dhuwur, resistance karat kimia, resistance oksidasi, nyandhang resistance, expansivity termal amba.Produk werni kothong zirconia digawe kanthi bal kothong zirconia, kanthi kekuatan suhu dhuwur lan stabilitas struktur porositas.
Aplikasi
Batu bata kothong alumina utamane digunakake ing reaktor gasifier industri petrokimia, industri karbon ireng, tungku induksi industri metalurgi, kiln down-draft, kiln anter jemput, tungku kawat molibdenum, tungku rod tungsten, tungku induksi, oven nitrogen, lan liya-liyane. suhu, tungku suhu super dhuwur.
Zirconia bata werni kothong digunakake ing peralatan suhu Ultra dhuwur kayata tutup pawon bagean saka materi jampel termal, kayata frekuensi medium tungku suhu dhuwur, reaktor ireng karbon, tungku kabel molybdenum, tungsten rod tungku, etc. Kinerja banget, paling aman paling. suhu operasi punika 2200 ℃, ing Metallurgical, Petrokimia, elektronik lan peralatan termal industri minangka kontak langsung karo semangat saka materi lining suhu dhuwur, efek nggunakake apik.
