冷熱沖擊試驗箱也是我們常說的高低溫沖擊試驗箱,主要用于對(dui)于復合材(cai)料在(zai)連續高(gao)溫或低溫的(de)(de)(de)沖(chong)擊環境(jing)下(xia)(xia)的(de)(de)(de)忍(ren)耐(nai)度測(ce)試,以測(ce)試材(cai)料在(zai)短時間(jian)內受(shou)到冷熱沖(chong)擊下(xia)(xia)的(de)(de)(de)物理傷害及化學變化。那么在(zai)測(ce)試之(zhi)后要怎么校準(zhun)試驗箱(xiang)的(de)(de)(de)溫度恢復時間(jian)呢?
按規(gui)定(ding)位(wei)置安裝溫(wen)(wen)度(du)丈(zhang)量(liang)傳(chuan)感器,將高溫(wen)(wen)箱和低溫(wen)(wen)箱的(de)溫(wen)(wen)度(du)控制器分別(bie)調理到所要求的(de)標準溫(wen)(wen)度(du)上;
分別使箱(xiang)體(ti)升(sheng)溫和降(jiang)溫,自冷熱沖擊箱(xiang)進入控溫狀態(tai)后(hou)穩(wen)定(ding)30min或(huo)按產品技術條件要求(qiu)穩(wen)定(ding)相應的時間,記錄丈量點的溫度(du)值;
冷熱沖(chong)擊箱將檢驗(yan)負載(zai)置入高溫裝(zhuang)備中,按產品(pin)技術條件要求或有(you)關標準的(de)規定選擇相應的(de)保持時間;
選擇冷熱沖擊箱(xiang)的(de)轉換(huan)時間,然后(hou)將檢驗(yan)負(fu)載由(you)高溫(wen)裝備轉入低(di)溫(wen)裝備,注(zhu)意視(shi)察和(he)記錄丈量點的(de)溫(wen)度;再按相同的(de)方法進行檢驗(yan)負(fu)載由(you)低(di)溫(wen)裝備向高溫(wen)裝備的(de)相反轉換(huan),注(zhu)意視(shi)察和(he)記錄丈量點的(de)溫(wen)度;
分別記(ji)錄(lu)檢驗冷(leng)熱沖擊箱負(fu)載(zai)從(cong)高溫(wen)(或低溫(wen))裝備轉換(huan)到(dao)低溫(wen)(或高溫(wen))裝備后至裝備丈量點溫(wen)度(du)恢復(fu)到(dao)檢驗負(fu)載(zai)放(fang)入之前的溫(wen)度(du)狀態所需(xu)要的最短(duan)時間。
