關于中空玻璃充氣知識，貴州防火玻璃廠家為您介紹

隨著國家有關建(jian)(jian)筑(zhu)節能的(de)(de)政策方針和(he)法(fa)規的(de)(de)實施、建(jian)(jian)筑(zhu)節能知識(shi)的(de)(de)逐漸普及，人們對(dui)節能配置高(gao)的(de)(de)中空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)需求也在不(bu)斷增(zeng)加(jia)，低(di)輻(fu)(fu)(fu)射(she)鍍膜玻(bo)(bo)(bo)(bo)璃(li)的(de)(de)規模化生產(chan)帶來的(de)(de)市場增(zeng)量的(de)(de)相對(dui)提高(gao)，使(shi)性能高(gao)中空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)的(de)(de)需求量的(de)(de)不(bu)斷增(zeng)加(jia)成為可能。于是出現了低(di)輻(fu)(fu)(fu)射(she)鍍膜中空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)方面越來越廣的(de)(de)應(ying)用，方興未艾。但(dan)低(di)輻(fu)(fu)(fu)射(she)玻(bo)(bo)(bo)(bo)璃(li)的(de)(de)應(ying)用帶來了我們以前(qian)不(bu)曾(ceng)遇(yu)到的(de)(de)兩個問題：（1）使(shi)用離線(xian)低(di)輻(fu)(fu)(fu)射(she)鍍膜制(zhi)作(zuo)中空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)，對(dui)密封壽(shou)命(ming)的(de)(de)要求變得多；（2）使(shi)用低(di)輻(fu)(fu)(fu)射(she)玻(bo)(bo)(bo)(bo)璃(li)解(jie)決熱輻(fu)(fu)(fu)射(she)問題之(zhi)后，降(jiang)低(di)中空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)空(kong)(kong)腔(qiang)內的(de)(de)熱對(dui)流(liu)就(jiu)變得迫切。　　   

中(zhong)空(kong)玻(bo)(bo)(bo)璃(li)充惰性(xing)氣(qi)(qi)體助(zhu)于同時改良密封壽命和(he)(he)降低(di)熱對(dui)流(liu)，而充氣(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)璃(li)所要的初(chu)始充氣(qi)(qi)濃度(du)(du)和(he)(he)氣(qi)(qi)密性(xing)，是(shi)解決這兩方面問(wen)題的基本保證。本文討論提高充氣(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)璃(li)的初(chu)始濃度(du)(du)所涉及的有關問(wen)題，如(ru)充氣(qi)(qi)中(zhong)空(kong)玻(bo)(bo)(bo)璃(li)的生產過程控制和(he)(he)產品質量檢測，旨在幫助(zhu)那些已(yi)經對(dui)中(zhong)空(kong)玻(bo)(bo)(bo)璃(li)充氣(qi)(qi)但濃度(du)(du)低(di)于90％和(he)(he)那些正在考慮上中(zhong)空(kong)玻(bo)(bo)(bo)璃(li)充氣(qi)(qi)設備的廠家(jia)選擇正確(que)的充氣(qi)(qi)設備。

1充氣的基本知識

一般說(shuo)來，充氣(qi)(qi)(qi)中空玻(bo)璃所使用(yong)的惰性氣(qi)(qi)(qi)體(ti)為氬氣(qi)(qi)(qi)，具有無(wu)色、無(wu)味、無(wu)毒的特點，其分子(zi)量較(jiao)空氣(qi)(qi)(qi)重38％，導(dao)熱系(xi)數比空氣(qi)(qi)(qi)小。

由于氬(ya)氣(qi)(qi)(qi)的密度比空(kong)氣(qi)(qi)(qi)大，因此(ci)，在(zai)(zai)中空(kong)玻(bo)璃充(chong)氣(qi)(qi)(qi)時，氬(ya)氣(qi)(qi)(qi)充(chong)（進）氣(qi)(qi)(qi)孔(kong)在(zai)(zai)下端、空(kong)氣(qi)(qi)(qi)的出（排）氣(qi)(qi)(qi)孔(kong)在(zai)(zai)上端，以置(zhi)換(huan)出中空(kong)玻(bo)璃內的空(kong)氣(qi)(qi)(qi)，達到所(suo)需(xu)要的氬(ya)氣(qi)(qi)(qi)濃(nong)度。

中空玻璃的(de)(de)充氣(qi)(qi)(qi)過程(cheng)實質(zhi)上是流(liu)(liu)動(dong)氣(qi)(qi)(qi)體從一種運(yun)動(dong)狀(zhuang)態(tai)轉移到(dao)另一種狀(zhuang)態(tai)的(de)(de)過程(cheng)，充氣(qi)(qi)(qi)質(zhi)量(liang)高與否(fou)和氣(qi)(qi)(qi)體產生層流(liu)(liu)（laminar）抑或是紊流(liu)(liu)（turbulence）有關。因此(ci)，討論中空玻璃充氣(qi)(qi)(qi)質(zhi)量(liang)不(bu)能(neng)離對于(yu)層流(liu)(liu)和紊流(liu)(liu)基本(ben)概念的(de)(de)討論。

層(ceng)流(liu)(liu)和(he)紊流(liu)(liu)是(shi)(shi)粘(zhan)(zhan)(zhan)性(xing)(xing)流(liu)(liu)體(ti)(ti)(ti)(ti)運(yun)(yun)(yun)(yun)動(dong)時慣(guan)性(xing)(xing)力(li)(li)(li)(li)(li)和(he)粘(zhan)(zhan)(zhan)性(xing)(xing)力(li)(li)(li)(li)(li)共同(tong)作用(yong)(yong)的(de)(de)(de)結(jie)果。粘(zhan)(zhan)(zhan)性(xing)(xing)流(liu)(liu)體(ti)(ti)(ti)(ti)運(yun)(yun)(yun)(yun)動(dong)與(yu)理(li)想流(liu)(liu)體(ti)(ti)(ti)(ti)運(yun)(yun)(yun)(yun)動(dong)的(de)(de)(de)主要區別(bie)是(shi)(shi)微團(tuan)(tuan)的(de)(de)(de)受(shou)力(li)(li)(li)(li)(li)除慣(guan)性(xing)(xing)力(li)(li)(li)(li)(li)外，還有粘(zhan)(zhan)(zhan)性(xing)(xing)力(li)(li)(li)(li)(li)。根據這兩種力(li)(li)(li)(li)(li)的(de)(de)(de)特點，它(ta)們對流(liu)(liu)體(ti)(ti)(ti)(ti)微團(tuan)(tuan)運(yun)(yun)(yun)(yun)動(dong)行(xing)為的(de)(de)(de)影響是(shi)(shi)不(bu)同(tong)的(de)(de)(de)。按照定(ding)義，粘(zhan)(zhan)(zhan)性(xing)(xing)力(li)(li)(li)(li)(li)的(de)(de)(de)作用(yong)(yong)是(shi)(shi)阻(zu)止(zhi)流(liu)(liu)體(ti)(ti)(ti)(ti)微團(tuan)(tuan)發生相對運(yun)(yun)(yun)(yun)動(dong)，而(er)慣(guan)性(xing)(xing)力(li)(li)(li)(li)(li)的(de)(de)(de)作用(yong)(yong)與(yu)粘(zhan)(zhan)(zhan)性(xing)(xing)力(li)(li)(li)(li)(li)的(de)(de)(de)作用(yong)(yong)正好(hao)相反(fan)，因此在粘(zhan)(zhan)(zhan)性(xing)(xing)流(liu)(liu)體(ti)(ti)(ti)(ti)流(liu)(liu)動(dong)中，流(liu)(liu)動(dong)的(de)(de)(de)行(xing)為決定(ding)于(yu)(yu)這兩種力(li)(li)(li)(li)(li)作用(yong)(yong)的(de)(de)(de)結(jie)果。在粘(zhan)(zhan)(zhan)性(xing)(xing)力(li)(li)(li)(li)(li)的(de)(de)(de)作用(yong)(yong)遠大(da)于(yu)(yu)慣(guan)性(xing)(xing)力(li)(li)(li)(li)(li)的(de)(de)(de)作用(yong)(yong)條(tiao)件下，氣體(ti)(ti)(ti)(ti)運(yun)(yun)(yun)(yun)動(dong)產生層(ceng)流(liu)(liu)，反(fan)之，在慣(guan)性(xing)(xing)力(li)(li)(li)(li)(li)的(de)(de)(de)作用(yong)(yong)遠大(da)于(yu)(yu)粘(zhan)(zhan)(zhan)性(xing)(xing)力(li)(li)(li)(li)(li)的(de)(de)(de)作用(yong)(yong)時，氣體(ti)(ti)(ti)(ti)運(yun)(yun)(yun)(yun)動(dong)產生紊流(liu)(liu)。

直觀地看，作為流體運動的一種簡單圖像，層流可以看成是彼此相鄰、并且具有“確認物質意義”的流層，或者說是不存在相互串動的“流體線元”，進行滑移運動的一種延伸。簡單地說，層流就是流體的分層流動。此時，運動中流體承受牛頓粘性應力，與固體之間反抗彼此滑移運動的力學機制沒有質差異。紊流的基本特點是有渦性、不規則性、隨機性、擴散性和耗散性，貴州防火玻璃廠家是一(yi)種由大小不等、頻(pin)率不同的(de)旋渦結構組(zu)成，使其物理量對(dui)時間(jian)和空間(jian)的(de)變(bian)化均表現出(chu)不規則的(de)隨機性。

目前，我國中(zhong)(zhong)空玻(bo)璃的(de)(de)(de)(de)充(chong)氣(qi)質量不高，是由(you)充(chong)氣(qi)過程中(zhong)(zhong)產(chan)生的(de)(de)(de)(de)紊流(liu)所造成的(de)(de)(de)(de)。假定充(chong)氣(qi)設備(bei)的(de)(de)(de)(de)傳感器只(zhi)識別(bie)中(zhong)(zhong)空玻(bo)璃排氣(qi)孔(kong)處收(shou)集到(dao)的(de)(de)(de)(de)惰性氣(qi)體(ti)的(de)(de)(de)(de)濃(nong)(nong)(nong)度(du)，且充(chong)氣(qi)中(zhong)(zhong)空玻(bo)璃的(de)(de)(de)(de)層流(liu)和紊流(liu)終給出(chu)的(de)(de)(de)(de)惰性氣(qi)體(ti)濃(nong)(nong)(nong)度(du)同(tong)樣(yang)符(fu)合(he)標(biao)準要求，人們用肉眼又無法(fa)區(qu)別(bie)哪片中(zhong)(zhong)空玻(bo)璃的(de)(de)(de)(de)惰性氣(qi)體(ti)在(zai)擴散(san)后的(de)(de)(de)(de)濃(nong)(nong)(nong)度(du)走向。如果采(cai)用高壓放電(dian)法(fa)對這(zhe)類(lei)充(chong)氣(qi)中(zhong)(zhong)空玻(bo)璃的(de)(de)(de)(de)初(chu)始濃(nong)(nong)(nong)度(du)進行在(zai)線(xian)檢測(ce)，所得出(chu)的(de)(de)(de)(de)濃(nong)(nong)(nong)度(du)就會(hui)(hui)(hui)高出(chu)擴散(san)后的(de)(de)(de)(de)實(shi)際濃(nong)(nong)(nong)度(du)。結(jie)果有兩種：1）如果廠(chang)家(jia)將存在(zai)紊流(liu)的(de)(de)(de)(de)產(chan)品判斷為(wei)合(he)格交付(fu)客(ke)戶或送到(dao)實(shi)驗(yan)室檢測(ce)，擴散(san)后的(de)(de)(de)(de)實(shi)際濃(nong)(nong)(nong)度(du)就會(hui)(hui)(hui)低(di)于開始測(ce)試(shi)的(de)(de)(de)(de)濃(nong)(nong)(nong)度(du)。2）這(zhe)種濃(nong)(nong)(nong)度(du)變化的(de)(de)(de)(de)充(chong)氣(qi)中(zhong)(zhong)空玻(bo)璃會(hui)(hui)(hui)困惑(huo)生產(chan)廠(chang)家(jia)，因(yin)為(wei)產(chan)品的(de)(de)(de)(de)密封并沒缺陷，且產(chan)品測(ce)試(shi)的(de)(de)(de)(de)只(zhi)是初(chu)始濃(nong)(nong)(nong)度(du)。

關于(yu)流體的層流和紊流的上述表述，在于(yu)揭示中空玻璃充(chong)氣過(guo)程(cheng)流體運動狀態轉變過(guo)程(cheng)中出(chu)現紊流的可能性及其特點。

2紊流(liu)對充氣過程及濃度測量的影(ying)響

充(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)產生紊(wen)流時，中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)腔內的(de)(de)(de)(de)部分空(kong)(kong)(kong)氣(qi)不(bu)能被充(chong)(chong)入的(de)(de)(de)(de)氬氣(qi)置(zhi)(zhi)換掉，因此(ci)，存(cun)(cun)在(zai)紊(wen)流的(de)(de)(de)(de)充(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)的(de)(de)(de)(de)初(chu)始(shi)濃度(du)(du)很難達到(dao)標(biao)準所規定的(de)(de)(de)(de)要求。此(ci)外，充(chong)(chong)氣(qi)過程中(zhong)(zhong)(zhong)(zhong)(zhong)所產生的(de)(de)(de)(de)紊(wen)流，使(shi)空(kong)(kong)(kong)氣(qi)仍存(cun)(cun)在(zai)于中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)空(kong)(kong)(kong)腔的(de)(de)(de)(de)中(zhong)(zhong)(zhong)(zhong)(zhong)央位置(zhi)(zhi)。當中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)出現(xian)(xian)(xian)紊(wen)流現(xian)(xian)(xian)象時，在(zai)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)排(pai)氣(qi)孔傳感器所檢(jian)測(ce)到(dao)的(de)(de)(de)(de)濃度(du)(du)，一(yi)般說來，應(ying)高于中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)腔體(ti)中(zhong)(zhong)(zhong)(zhong)(zhong)央湍流的(de)(de)(de)(de)空(kong)(kong)(kong)氣(qi)，而中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)的(de)(de)(de)(de)惰性(xing)氣(qi)體(ti)的(de)(de)(de)(de)擴散需要6~8小(xiao)時。如(ru)果使(shi)用該方(fang)法(fa)進行(xing)在(zai)線檢(jian)測(ce)，則(ze)所測(ce)出的(de)(de)(de)(de)濃度(du)(du)高于擴散后(hou)的(de)(de)(de)(de)實(shi)(shi)際濃度(du)(du)。因此(ci)，我們不(bu)能將這(zhe)種檢(jian)測(ce)方(fang)法(fa)作為充(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)的(de)(de)(de)(de)在(zai)線檢(jian)測(ce)手段(duan)。否則(ze)，在(zai)充(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)內出現(xian)(xian)(xian)紊(wen)流現(xian)(xian)(xian)象條件下，會給出檢(jian)測(ce)人(ren)員(yuan)錯誤的(de)(de)(de)(de)判(pan)斷。如(ru)存(cun)(cun)在(zai)紊(wen)流的(de)(de)(de)(de)充(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)，采用高壓放電法(fa)檢(jian)測(ce)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)的(de)(de)(de)(de)位置(zhi)(zhi)應(ying)盡(jin)可能靠近間隔條位置(zhi)(zhi)。按(an)照廠家建議的(de)(de)(de)(de)三(san)個測(ce)量點(dian)，正好避開了充(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)的(de)(de)(de)(de)紊(wen)流氣(qi)體(ti)，即空(kong)(kong)(kong)氣(qi)位置(zhi)(zhi)，所給出的(de)(de)(de)(de)濃度(du)(du)為惰性(xing)氣(qi)體(ti)的(de)(de)(de)(de)濃度(du)(du)。因此(ci)，在(zai)充(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)放置(zhi)(zhi)6~8小(xiao)時后(hou)，得出正確的(de)(de)(de)(de)濃度(du)(du)數字(zi)。據調查，有(you)(you)的(de)(de)(de)(de)廠家自檢(jian)的(de)(de)(de)(de)充(chong)(chong)氣(qi)中(zhong)(zhong)(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)初(chu)始(shi)濃度(du)(du)在(zai)90％以上(shang)，但經(jing)第(di)三(san)方(fang)測(ce)量實(shi)(shi)際濃度(du)(du)低于90％，有(you)(you)的(de)(de)(de)(de)還不(bu)足70％。通過對這(zhe)些濃度(du)(du)差別大的(de)(de)(de)(de)充(chong)(chong)氣(qi)玻(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)密封的(de)(de)(de)(de)外觀檢(jian)測(ce)，我們很難的(de)(de)(de)(de)找出密封缺(que)陷，因此(ci)，我們推斷出現(xian)(xian)(xian)這(zhe)種現(xian)(xian)(xian)象的(de)(de)(de)(de)原因之一(yi)，是由(you)于紊(wen)流造成的(de)(de)(de)(de)。

但是，這種檢(jian)(jian)測方(fang)法(fa)屬于產品質量的(de)(de)(de)事后檢(jian)(jian)測。充(chong)(chong)(chong)氣(qi)中空玻(bo)璃(li)放(fang)置6-8小(xiao)時(shi)后，二道密(mi)封膠(jiao)基(ji)本固化，如果充(chong)(chong)(chong)氣(qi)中空玻(bo)璃(li)的(de)(de)(de)濃(nong)(nong)度(du)達(da)不(bu)到(dao)要求(qiu)(qiu)，則對(dui)已充(chong)(chong)(chong)氣(qi)的(de)(de)(de)中空玻(bo)璃(li)的(de)(de)(de)返(fan)工是一件費(fei)時(shi)費(fei)力的(de)(de)(de)事情。此外(wai)還有兩(liang)種可能：（1）如果對(dui)充(chong)(chong)(chong)氣(qi)方(fang)法(fa)不(bu)改進(jin)的(de)(de)(de)話，我們(men)仍無法(fa)保(bao)證返(fan)工的(de)(de)(de)產品的(de)(de)(de)充(chong)(chong)(chong)氣(qi)濃(nong)(nong)度(du)達(da)到(dao)要求(qiu)(qiu)；（2）采用普通的(de)(de)(de)充(chong)(chong)(chong)氣(qi)方(fang)法(fa)，即(ji)自(zi)然充(chong)(chong)(chong)氣(qi)和充(chong)(chong)(chong)氣(qi)與(yu)強制抽氣(qi)法(fa)，不(bu)可避(bi)開發生紊流現象(xiang)，即(ji)使是隨機抽查檢(jian)(jian)測的(de)(de)(de)玻(bo)璃(li)達(da)到(dao)濃(nong)(nong)度(du)要求(qiu)(qiu)，除(chu)非我們(men)有充(chong)(chong)(chong)氣(qi)過程(cheng)每片玻(bo)璃(li)的(de)(de)(de)實時(shi)監控數字，否則，我們(men)也無法(fa)確(que)切地保(bao)證整個批次的(de)(de)(de)充(chong)(chong)(chong)氣(qi)玻(bo)璃(li)都合格。

由此可見，除非我(wo)(wo)們采用的(de)(de)(de)充氣(qi)(qi)設備能(neng)(neng)夠有效地避開紊(wen)流(liu)出(chu)現、抑(yi)或保持(chi)充氣(qi)(qi)過(guo)(guo)程的(de)(de)(de)穩定的(de)(de)(de)層流(liu)，否則，我(wo)(wo)們就不能(neng)(neng)排除在(zai)(zai)線(xian)檢測的(de)(de)(de)濃度的(de)(de)(de)真偽(wei)。進一步說，在(zai)(zai)此條件下，我(wo)(wo)們保證充氣(qi)(qi)中空玻(bo)璃(li)的(de)(de)(de)濃度的(de)(de)(de)正確(que)方法，只能(neng)(neng)是對充氣(qi)(qi)中空玻(bo)璃(li)的(de)(de)(de)生產過(guo)(guo)程進行控(kong)制，而不是產品的(de)(de)(de)質(zhi)量控(kong)制。

3充氣(qi)中空(kong)玻璃(li)的(de)生(sheng)產控制

充(chong)氣(qi)中(zhong)空玻(bo)璃的(de)生產(chan)(chan)過(guo)程(cheng)控制(zhi)(zhi)(zhi)(zhi)（production process control）概念(nian)是(shi)(shi)，為(wei)保(bao)持(chi)充(chong)氣(qi)中(zhong)空玻(bo)璃生產(chan)(chan)過(guo)程(cheng)處(chu)于受控狀態，對(dui)(dui)(dui)影響充(chong)氣(qi)濃(nong)度(du)(du)(du)(du)(du)質(zhi)量(liang)的(de)生產(chan)(chan)過(guo)程(cheng)所(suo)采(cai)取的(de)作(zuo)業技術和生產(chan)(chan)過(guo)程(cheng)的(de)分(fen)析(xi)、診(zhen)斷和實(shi)(shi)時(shi)監控。它的(de)作(zuo)用(yong)在于對(dui)(dui)(dui)生產(chan)(chan)過(guo)程(cheng)的(de)質(zhi)量(liang)控制(zhi)(zhi)(zhi)(zhi)進行(xing)系統(tong)安排，對(dui)(dui)(dui)直(zhi)接或間接影響過(guo)程(cheng)質(zhi)量(liang)的(de)因素進行(xing)控制(zhi)(zhi)(zhi)(zhi)并制(zhi)(zhi)(zhi)(zhi)定實(shi)(shi)施控制(zhi)(zhi)(zhi)(zhi)計劃，保(bao)持(chi)過(guo)程(cheng)質(zhi)量(liang)。氬(ya)氣(qi)是(shi)(shi)無色無味氣(qi)體，其充(chong)氣(qi)濃(nong)度(du)(du)(du)(du)(du)不(bu)易測(ce)量(liang)。目(mu)(mu)前的(de)測(ce)試方(fang)法大體可以分(fen)為(wei)兩種：（1）傳感器(qi)對(dui)(dui)(dui)從排氣(qi)孔(kong)所(suo)收集的(de)氣(qi)體與所(suo)設(she)置的(de)氣(qi)體濃(nong)度(du)(du)(du)(du)(du)相(xiang)比較，以判斷是(shi)(shi)否達到要求；（2）傳感器(qi)對(dui)(dui)(dui)排氣(qi)孔(kong)所(suo)收集的(de)氣(qi)體與所(suo)設(she)置的(de)氣(qi)體濃(nong)度(du)(du)(du)(du)(du)進行(xing)動(dong)態比較并給出濃(nong)度(du)(du)(du)(du)(du)、氣(qi)壓和流速(su)等實(shi)(shi)時(shi)曲(qu)線(xian)(xian)，不(bu)但(dan)從濃(nong)度(du)(du)(du)(du)(du)上判斷而且從曲(qu)線(xian)(xian)形狀上判斷，充(chong)氣(qi)的(de)實(shi)(shi)際濃(nong)度(du)(du)(du)(du)(du)。二(er)(er)者相(xiang)比，由于二(er)(er)種方(fang)法不(bu)只(zhi)是(shi)(shi)兩個(ge)值(zhi)的(de)比較，而是(shi)(shi)對(dui)(dui)(dui)整個(ge)充(chong)氣(qi)過(guo)程(cheng)的(de)描(miao)述，是(shi)(shi)目(mu)(mu)前充(chong)氣(qi)過(guo)程(cheng)實(shi)(shi)時(shi)監控的(de)生產(chan)(chan)控制(zhi)(zhi)(zhi)(zhi)手段。

結語

充(chong)氣(qi)中空玻(bo)璃(li)的(de)(de)生產過程控制是(shi)增加充(chong)氣(qi)濃(nong)(nong)度(du)的(de)(de)重(zhong)要保證(zheng)。相比(bi)之下，充(chong)氣(qi)中空玻(bo)璃(li)的(de)(de)質量控制是(shi)事后檢測，是(shi)保證(zheng)充(chong)氣(qi)初始(shi)濃(nong)(nong)度(du)的(de)(de)輔助手段。

紊流是造成我國中空玻璃充氣質量低的重要原因，使用智能控制充氣方法，不但能保證充氣過程的層流以達到標準所規定的初始濃度，而且具有充氣速度快和惰性氣體消耗量少的優點。此外，充氣設備的性價比好，貴州防火玻璃廠家具有投(tou)資較小、經用的(de)特點，對(dui)于(yu)那些亟(ji)需提高充(chong)氣水平卻苦于(yu)找不到好的(de)充(chong)氣方法的(de)企業，不失(shi)為(wei)一種較好的(de)選擇。
