節能中空玻璃的生產過程控制概念是，為確保節能中空玻璃生產過程處于受控狀態，對影響節能中空玻璃充(chong)氣(qi)濃(nong)度(du)質(zhi)量的(de)生(sheng)產(chan)過程(cheng)所采(cai)取的(de)作(zuo)業技術和(he)生(sheng)產(chan)過程(cheng)的(de)分析、診(zhen)斷(duan)和(he)實時監控。它的(de)作(zuo)用在(zai)于對生(sheng)產(chan)過程(cheng)的(de)質(zhi)量控制(zhi)進(jin)行(xing)系統安排，對直接或間接影響過程(cheng)質(zhi)量的(de)因素進(jin)行(xing)重點控制(zhi)并制(zhi)定實施控制(zhi)計劃，確保(bao)過程(cheng)質(zhi)量。氬(ya)氣(qi)是無(wu)(wu)色無(wu)(wu)味氣(qi)體，其充(chong)氣(qi)濃(nong)度(du)不易(yi)測量。目前(qian)的(de)測試方法(fa)大體可以分為兩種：

（1）傳感器對從排氣孔所(suo)收集的(de)氣體與所(suo)設置的(de)氣體濃度相(xiang)比較(jiao)，以判斷是否達到要求。

（2）傳感器(qi)對(dui)(dui)(dui)(dui)(dui)排氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)孔所(suo)收集的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)與所(suo)設置的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)濃(nong)(nong)(nong)度(du)(du)進行(xing)動態比較(jiao)并給(gei)出(chu)濃(nong)(nong)(nong)度(du)(du)、氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)壓和流(liu)速(su)等實時(shi)曲線(xian)，不(bu)(bu)但從濃(nong)(nong)(nong)度(du)(du)上判(pan)斷而(er)(er)且從曲線(xian)形狀上判(pan)斷，充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)實際濃(nong)(nong)(nong)度(du)(du)。二者相比，由于第二種(zhong)方(fang)法不(bu)(bu)僅僅是(shi)(shi)兩個(ge)值的(de)(de)(de)(de)(de)(de)比較(jiao)，而(er)(er)是(shi)(shi)對(dui)(dui)(dui)(dui)(dui)整個(ge)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)過(guo)程(cheng)(cheng)的(de)(de)(de)(de)(de)(de)描述，是(shi)(shi)目前充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)過(guo)程(cheng)(cheng)實時(shi)監控的(de)(de)(de)(de)(de)(de)先進的(de)(de)(de)(de)(de)(de)生(sheng)產(chan)(chan)控制(zhi)(zhi)手(shou)段。充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)濃(nong)(nong)(nong)度(du)(du)的(de)(de)(de)(de)(de)(de)質(zhi)量控制(zhi)(zhi)的(de)(de)(de)(de)(de)(de)特點是(shi)(shi)事后(hou)性(xing)，屬于不(bu)(bu)合(he)格產(chan)(chan)品(pin)檢(jian)(jian)(jian)測(ce)。歐洲(zhou)中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)標準(zhun)EN1279-6的(de)(de)(de)(de)(de)(de)生(sheng)產(chan)(chan)控制(zhi)(zhi)實際上是(shi)(shi)指對(dui)(dui)(dui)(dui)(dui)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)合(he)片(pian)(pian)(pian)濃(nong)(nong)(nong)度(du)(du)的(de)(de)(de)(de)(de)(de)測(ce)量，應(ying)該(gai)理解為對(dui)(dui)(dui)(dui)(dui)產(chan)(chan)品(pin)的(de)(de)(de)(de)(de)(de)質(zhi)量控制(zhi)(zhi)或檢(jian)(jian)(jian)測(ce)，而(er)(er)不(bu)(bu)是(shi)(shi)真正意(yi)(yi)義上的(de)(de)(de)(de)(de)(de)生(sheng)產(chan)(chan)過(guo)程(cheng)(cheng)控制(zhi)(zhi)。對(dui)(dui)(dui)(dui)(dui)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)初始濃(nong)(nong)(nong)度(du)(du)的(de)(de)(de)(de)(de)(de)抽樣(yang)檢(jian)(jian)(jian)測(ce)規定(ding)，1片(pian)(pian)(pian)/1000片(pian)(pian)(pian)/班(ban)，至少3片(pian)(pian)(pian)，當每(mei)班(ban)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)不(bu)(bu)足100片(pian)(pian)(pian)時(shi)，抽查1片(pian)(pian)(pian)。充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)中(zhong)的(de)(de)(de)(de)(de)(de)氬(ya)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)需(xu)(xu)要(yao)(yao)大約6~8小時(shi)才(cai)能完全(quan)(quan)擴散(san)，因(yin)(yin)此，對(dui)(dui)(dui)(dui)(dui)中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)氬(ya)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)初始濃(nong)(nong)(nong)度(du)(du)的(de)(de)(de)(de)(de)(de)檢(jian)(jian)(jian)測(ce)需(xu)(xu)在氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)完全(quan)(quan)擴散(san)后(hou)才(cai)能進行(xing)。因(yin)(yin)此，無論是(shi)(shi)對(dui)(dui)(dui)(dui)(dui)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)濃(nong)(nong)(nong)度(du)(du)的(de)(de)(de)(de)(de)(de)在線(xian)檢(jian)(jian)(jian)測(ce)抑(yi)或是(shi)(shi)在惰性(xing)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)完全(quan)(quan)擴散(san)的(de)(de)(de)(de)(de)(de)6~8小時(shi)后(hou)再檢(jian)(jian)(jian)測(ce)，都只能是(shi)(shi)對(dui)(dui)(dui)(dui)(dui)產(chan)(chan)品(pin)合(he)格與否的(de)(de)(de)(de)(de)(de)判(pan)斷。假如這種(zhong)抽樣(yang)檢(jian)(jian)(jian)測(ce)的(de)(de)(de)(de)(de)(de)結果是(shi)(shi)總(zong)體(ti)不(bu)(bu)合(he)格，則問題(ti)的(de)(de)(de)(de)(de)(de)發現(xian)已經(jing)為時(shi)過(guo)晚。綜上所(suo)述，造成充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)初始濃(nong)(nong)(nong)度(du)(du)低的(de)(de)(de)(de)(de)(de)主要(yao)(yao)原(yuan)因(yin)(yin)在于充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)過(guo)程(cheng)(cheng)中(zhong)出(chu)現(xian)的(de)(de)(de)(de)(de)(de)紊(wen)流(liu)現(xian)象。對(dui)(dui)(dui)(dui)(dui)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)生(sheng)產(chan)(chan)控制(zhi)(zhi)的(de)(de)(de)(de)(de)(de)意(yi)(yi)義在于對(dui)(dui)(dui)(dui)(dui)整個(ge)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)過(guo)程(cheng)(cheng)進行(xing)實時(shi)監控，從而(er)(er)有效地避免中(zhong)空(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)過(guo)程(cheng)(cheng)中(zhong)可能出(chu)現(xian)的(de)(de)(de)(de)(de)(de)紊(wen)流(liu)現(xian)象，提高和保證充(chong)(chong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)質(zhi)量的(de)(de)(de)(de)(de)(de)穩(wen)定(ding)性(xing)。
