試驗(yàn)標(biāo)準(zhǔn)TEST STANDARD:本產(chǎn)品符合GB/T2951,UL1581 ASTM-D5423,VDE,CCC 等試驗(yàn)標(biāo)準(zhǔn)
產(chǎn)品特點(diǎn) PRODUCT FEATURES:
ul換氣式老化試驗(yàn)機(jī)本機(jī)適用于橡膠、塑膠、人造皮革及其他化學(xué)合成產(chǎn)品測試其材質(zhì)之老化,延伸率、抗張力等變化情形;
ul換氣式老化試驗(yàn)機(jī)本機(jī)在試驗(yàn)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(qiáng)度及伸長率,本機(jī)以熱風(fēng)循環(huán)方式,促使試片老化,內(nèi)箱密閉性佳,具有抽換內(nèi)箱空氣裝置,設(shè)有超溫自動(dòng)切斷保護(hù)。
l 采用高精度微電腦控制器,智慧型PID自動(dòng)控制加溫系統(tǒng),控溫精度高。
l 多翼離心風(fēng)輪,強(qiáng)制送風(fēng),確保實(shí)驗(yàn)機(jī)內(nèi)部溫度均勻穩(wěn)定。
l 懸掛架與隔層架可自由拆裝,懸掛架轉(zhuǎn)速10r/m。
l 附數(shù)顯瓦特小時(shí)計(jì)及計(jì)時(shí)器,具換氣量測試功能。
l 采用簡便換氣量調(diào)節(jié)系統(tǒng),可方便調(diào)節(jié)新鮮空氣的換氣量。
l 觀測視窗明亮寬廣,方便觀察實(shí)驗(yàn)產(chǎn)品情況
l 內(nèi)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(hù)裝置,確保機(jī)臺可靠運(yùn)轉(zhuǎn)。
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)
