Deskripsi Produk
Berbagai Produk
Flexible graphite solutions encompass sheets, foil, tape, strips, and paper-form variants, secara kolektif dikenal sebagai expanded graphite materials.
Proses Produksi
Natural graphite flakes undergo chemical intercalation followed by rapid thermal expansion at 800-1000°C, creating exfoliated graphite particles with a bulk density of ~3 kg/m3.These expanded particles are mechanically compacted into continuous coils or sheet formats without adhesives or additives. Partikel-partikel yang diperluas ini secara mekanis dikompakkan menjadi kumparan atau lembaran berturut-turut tanpa adhesives atau aditif., memastikan 99%+ kemurnian.
Keuntungan Utama
-
Stabilitas Lingkungan: Resists chemical degradation, ionizing radiation, and thermal extremes (-200°C sampai +3000°C)
-
Kinerja Mekanis: Menjaga 85%+ kompresi recovery rate after cyclic loading
-
Kompatibilitas antarmuka: Combines with stainless steel/copper sheets via lamination for hybrid structural materials (Menggabungkan dengan lembaran baja tahan karat/tembaga melalui laminasi untuk bahan struktural hibrida)
Aplikasi Industri
-
Sistem penyegelan dinamis.: Primary material for rotating shaft packing rings in pumps/valves
-
Fabrikasi Gasket Komposit: Metal-reinforced multilayer sheets die-cut into custom flange gaskets
-
Direct-Form Components: Thickened plates (3-5mm) processed into low-pressure seals or thermal barriers: lempeng tebal (3-5mm) diproses menjadi low-pressure seals atau hambatan termal
