Bubuk Alumina Bunder kanggo Bahan Antarmuka Termal
Deskripsi Produk
Alumina bundher seri HRK diprodhuksi kanthi metode leleh-jet suhu dhuwur sing berkembang ing wangun Al2O3 sing ora duwe aturan baku, lan banjur ngalami screening, pemurnian lan proses liyane kanggo entuk produk pungkasan.Alumina sing dipikolehi nduweni tingkat spheroidisasi sing dhuwur, distribusi ukuran partikel sing bisa dikontrol lan kemurnian dhuwur.Amarga sifat unik kayata konduktivitas termal sing dhuwur lan mobilitas sing apik, Produk kasebut wis akeh digunakake minangka ngisi bahan antarmuka termal, plastik rekayasa termal lan Laminates Tembaga-Clad adhedhasar aluminium lan liya-liyane.
