換氣老化試驗機(jī)操作方法及換氣計算法   

一、 換氣老化試驗機(jī)操作方法：                                    

1. 在電源接通下打開面板電源開關(guān)和加熱開關(guān)；                                        

2 .在溫控器上設(shè)置材料所需溫度；                                        

3 .溫度達(dá)到材料所需溫度，打開試驗機(jī)箱門把制作好的樣品放置在試驗機(jī)旋轉(zhuǎn)盤上； 3.4 放好樣品后關(guān)上試驗機(jī)箱門打開旋轉(zhuǎn)開關(guān)并作好時間記錄；                             

二、  換氣老化試驗機(jī)換氣計算法：                                           

  N= 3590（X-Y）                          

  V×D×△T                           

  注釋：N：相當(dāng)于1小時之空氣交換次數(shù)                                 

        X：換氣中之消耗電量WH                                     

        Y：無換氣中之消耗電量WH                                  

        V：老化爐內(nèi)部全部容積（cm³）                                  

        D：老化爐周圍空氣之密度（g/cm³）                                   

        △T：老化爐內(nèi)外之溫度差                                       

 三、換氣老化試驗機(jī)注意事項：                                        

1. 經(jīng)常保持機(jī)臺外觀整潔、干凈；                                          

2. 定期檢查轉(zhuǎn)盤、馬達(dá)和減速機(jī)是否正常；                                          

3. 檢查散熱風(fēng)扇運(yùn)轉(zhuǎn)是否正常，并加潤滑油；
