海韻牌BT-7038型低溫裝置絕熱用膨脹珍珠巖Chaton brand BT-7038 type cryogenic device adiabatic with expansive pearlite執(zhí)行標(biāo)準(zhǔn)： JC/T 1020-2007Execution standard: JC/T 1020-2007　　用于空氣分離設(shè)備冷箱、低溫液體容器及其他低溫裝置絕熱用膨脹珍珠巖。其使用溫度范圍為 77K- 常溫（ -196℃ - 常溫）。執(zhí)行標(biāo)準(zhǔn)： JC/T 1020-2007　　Used in air separation equipment box, cryogenic liquid containers and other cryogenic device adiabatic with expansive pearlite. Its use temperature scope for 77K- normal temperature ( -196℃ - normal temperature). Execution standard: JC/T 1020-2007 安息角Rest Angle　　表征膨脹珍珠巖流動(dòng)性的指標(biāo)，流動(dòng)性越好，越容易充滿填充空間。流動(dòng)性用自然傾角，即用水平面與撒在該水平面上的粉末所形成的圓錐體表面之間的夾角來表示。　　Characterization of expansive pearlite liquidity index, liquidity more better, more easily filled with filling space. Liquidity by natural inclination, namely rephrases in the horizontal plane and a horizontal plane and the powder surface by the formation of the cone Angle between prond. 振實(shí)密度Vibration compaction density　　檢驗(yàn)膨脹珍珠巖顆粒強(qiáng)度的指標(biāo)，顆粒強(qiáng)度高，振實(shí)密度**小，顆粒強(qiáng)度低，振實(shí)密度**大?！　nspection expanded perlite granule's strength index, particle high intensity, vibration compaction density is small, particle of low intensity, and vibration compaction density is big.膨脹珍珠巖的物理性能Of expansive pearlite physical properties
