LX-8826A UL換氣式老化試驗機
CONVECTION AND VENTILATION AGING OVEN
試驗標準TEST STANDARD:本產品符合GB/T2951,UL1581 ASTM-D5423,VDE,CCC 等試驗標準
產品特點 PRODUCT FEATURES:
ul換氣式老化試驗機本機適用于橡膠、塑膠、人造皮革及其他化學合成產品測試其材質之老化,延伸率、抗張力等變化情形;
ul換氣式老化試驗機本機在試驗電線電纜絕緣體或被覆之橡塑膠試片,以比較試片老化前與老化后之抗拉強度及伸長率,本機以熱風循環方式,促使試片老化,內箱密閉性佳,具有抽換內箱空氣裝置,設有超溫自動切斷保護。
l 采用高精度微電腦控制器,智慧型PID自動控制加溫系統,控溫精度高。
l 多翼離心風輪,強制送風,確保實驗機內部溫度均勻穩定。
l 懸掛架與隔層架可自由拆裝,懸掛架轉速10r/m。
l 附數顯瓦特小時計及計時器,具換氣量測試功能。
l 采用簡便換氣量調節系統,可方便調節新鮮空氣的換氣量。
l 觀測視窗明亮寬廣,方便觀察實驗產品情況
l 內箱采用不銹鋼鏡面處理,外箱采用電解板靜電噴涂。
l 多層安全保護裝置,確保機臺可靠運轉。
換氣率測定方法:
N=3590 (X-Y)x2 VxDxT
where:
l N: number of changes of air per hour
X: Power consumption during air change (W)
Y: Power consumption during no air change (W)
V: total volume of oven (cm3)
D: Density of oven ambient air (g/cm3)
T: Temperature difference inside/outside oven (°C)
