充氣節能中空玻璃的生產過程控制概念是，為確保充氣節能中空玻璃中空玻璃生(sheng)(sheng)產(chan)過(guo)程(cheng)處于受控(kong)(kong)狀態，對影響充(chong)氣(qi)(qi)濃度(du)質(zhi)(zhi)量(liang)的生(sheng)(sheng)產(chan)過(guo)程(cheng)所采取的作業技術(shu)和(he)(he)生(sheng)(sheng)產(chan)過(guo)程(cheng)的分(fen)析、診斷和(he)(he)實時監控(kong)(kong)。它的作用(yong)在于對生(sheng)(sheng)產(chan)過(guo)程(cheng)的質(zhi)(zhi)量(liang)控(kong)(kong)制進(jin)行系(xi)統安排，對直接或間接影響過(guo)程(cheng)質(zhi)(zhi)量(liang)的因(yin)素(su)進(jin)行重點(dian)控(kong)(kong)制并制定實施(shi)控(kong)(kong)制計劃，確(que)保過(guo)程(cheng)質(zhi)(zhi)量(liang)。氬氣(qi)(qi)是無色(se)無味氣(qi)(qi)體，其(qi)充(chong)氣(qi)(qi)濃度(du)不易測量(liang)。

目前的測(ce)試方法大體可以分(fen)為兩種：

（1）傳感(gan)器對從(cong)排氣(qi)孔所收集的氣(qi)體(ti)與所設置的氣(qi)體(ti)濃度相比較，以判斷是否達(da)到要(yao)求。

（2）傳(chuan)感器(qi)對(dui)(dui)排氣(qi)孔所收集(ji)的(de)(de)(de)(de)(de)氣(qi)體與所設置的(de)(de)(de)(de)(de)氣(qi)體濃(nong)度進(jin)(jin)行(xing)(xing)動(dong)態比較并給(gei)出濃(nong)度、氣(qi)壓和流(liu)速(su)等實(shi)時(shi)曲線(xian)(xian)，不(bu)但從濃(nong)度上(shang)判斷(duan)而且從曲線(xian)(xian)形狀上(shang)判斷(duan)，充(chong)(chong)(chong)氣(qi)的(de)(de)(de)(de)(de)實(shi)際濃(nong)度。二者相比，由于(yu)第二種方法不(bu)僅僅是(shi)兩個(ge)值的(de)(de)(de)(de)(de)比較，而是(shi)對(dui)(dui)整個(ge)充(chong)(chong)(chong)氣(qi)過(guo)程(cheng)的(de)(de)(de)(de)(de)描述，是(shi)目前充(chong)(chong)(chong)氣(qi)過(guo)程(cheng)實(shi)時(shi)監控(kong)的(de)(de)(de)(de)(de)先(xian)進(jin)(jin)的(de)(de)(de)(de)(de)生產(chan)(chan)(chan)控(kong)制手段(duan)。充(chong)(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)濃(nong)度的(de)(de)(de)(de)(de)質(zhi)(zhi)量控(kong)制的(de)(de)(de)(de)(de)特點是(shi)事后(hou)性，屬于(yu)不(bu)合格產(chan)(chan)(chan)品檢(jian)(jian)(jian)測(ce)。歐洲中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)標準EN1279-6的(de)(de)(de)(de)(de)生產(chan)(chan)(chan)控(kong)制實(shi)際上(shang)是(shi)指對(dui)(dui)充(chong)(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)合片濃(nong)度的(de)(de)(de)(de)(de)測(ce)量，應該理解為對(dui)(dui)產(chan)(chan)(chan)品的(de)(de)(de)(de)(de)質(zhi)(zhi)量控(kong)制或(huo)檢(jian)(jian)(jian)測(ce)，而不(bu)是(shi)真(zhen)正意義(yi)上(shang)的(de)(de)(de)(de)(de)生產(chan)(chan)(chan)過(guo)程(cheng)控(kong)制。對(dui)(dui)充(chong)(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)初(chu)始(shi)濃(nong)度的(de)(de)(de)(de)(de)抽(chou)樣(yang)檢(jian)(jian)(jian)測(ce)規(gui)定，1片/1000片/班(ban)，至少3片，當每班(ban)充(chong)(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)不(bu)足100片時(shi)，抽(chou)查1片。充(chong)(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)(de)(de)氬氣(qi)需要(yao)(yao)大約6~8小(xiao)時(shi)才能(neng)完(wan)(wan)全(quan)擴(kuo)散(san)，因(yin)(yin)此(ci)，對(dui)(dui)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)氬氣(qi)初(chu)始(shi)濃(nong)度的(de)(de)(de)(de)(de)檢(jian)(jian)(jian)測(ce)需在(zai)(zai)(zai)(zai)氣(qi)體完(wan)(wan)全(quan)擴(kuo)散(san)后(hou)才能(neng)進(jin)(jin)行(xing)(xing)。因(yin)(yin)此(ci)，無(wu)論是(shi)對(dui)(dui)充(chong)(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)濃(nong)度的(de)(de)(de)(de)(de)在(zai)(zai)(zai)(zai)線(xian)(xian)檢(jian)(jian)(jian)測(ce)抑或(huo)是(shi)在(zai)(zai)(zai)(zai)惰性氣(qi)體完(wan)(wan)全(quan)擴(kuo)散(san)的(de)(de)(de)(de)(de)6~8小(xiao)時(shi)后(hou)再(zai)檢(jian)(jian)(jian)測(ce)，都只能(neng)是(shi)對(dui)(dui)產(chan)(chan)(chan)品合格與否的(de)(de)(de)(de)(de)判斷(duan)。假(jia)如這種抽(chou)樣(yang)檢(jian)(jian)(jian)測(ce)的(de)(de)(de)(de)(de)結果是(shi)總體不(bu)合格，則問題的(de)(de)(de)(de)(de)發現已經(jing)為時(shi)過(guo)晚(wan)。綜上(shang)所述，造成充(chong)(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)初(chu)始(shi)濃(nong)度低的(de)(de)(de)(de)(de)主(zhu)要(yao)(yao)原因(yin)(yin)在(zai)(zai)(zai)(zai)于(yu)充(chong)(chong)(chong)氣(qi)過(guo)程(cheng)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)出現的(de)(de)(de)(de)(de)紊流(liu)現象(xiang)。對(dui)(dui)充(chong)(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)生產(chan)(chan)(chan)控(kong)制的(de)(de)(de)(de)(de)意義(yi)在(zai)(zai)(zai)(zai)于(yu)對(dui)(dui)整個(ge)充(chong)(chong)(chong)氣(qi)過(guo)程(cheng)進(jin)(jin)行(xing)(xing)實(shi)時(shi)監控(kong)，從而有效地避(bi)免中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)充(chong)(chong)(chong)氣(qi)過(guo)程(cheng)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)可能(neng)出現的(de)(de)(de)(de)(de)紊流(liu)現象(xiang)，提高和保證充(chong)(chong)(chong)氣(qi)質(zhi)(zhi)量的(de)(de)(de)(de)(de)穩定性。
