臭氧(yang)老化箱(xiang)模(mo)擬和強化大氣中的(de)(de)臭氧(yang)條件，研(yan)究臭氧(yang)對橡(xiang)膠(jiao)(jiao)的(de)(de)作用(yong)(yong)規律(lv)，快速(su)鑒定和評價橡(xiang)膠(jiao)(jiao)抗臭氧(yang)老(lao)化性能與抗臭氧(yang)劑防護效能的(de)(de)方法，進而采取有效的(de)(de)防老(lao)化措施(shi)，以提高(gao)橡(xiang)膠(jiao)(jiao)制品的(de)(de)使(shi)用(yong)(yong)壽命。由無聲高效(xiao)臭氧發生(sheng)(sheng)(sheng)器發生(sheng)(sheng)(sheng)的(de)臭氧氣體，和一定量的(de)已(yi)處理的(de)空氣，在交換(huan)器中混合(he)后(hou)送入試驗(yan)箱(xiang)，紫(zi)外(wai)檢測儀將連(lian)續在線(xian)檢測到的(de)臭氧濃度，反饋到臭氧發生(sheng)(sheng)(sheng)器控制系(xi)統(tong)，使控制系(xi)統(tong)根據設(she)定值有(you)效(xiao)的(de)控制臭氧的(de)發生(sheng)(sheng)(sheng)，從而試驗(yan)箱(xiang)保(bao)持設(she)定的(de)臭氧濃度，另由加熱加濕系(xi)統(tong)工作，滿足(zu)試驗(yan)條(tiao)件(jian)。
由(you)臭(chou)氧控(kong)(kong)制系(xi)統(tong)(tong)、溫度(du)(du)控(kong)(kong)制系(xi)統(tong)(tong)、濕(shi)度(du)(du)控(kong)(kong)制系(xi)統(tong)(tong)組成:臭(chou)氧控(kong)(kong)制系(xi)統(tong)(tong)由(you)臭(chou)氧發生器(qi)、臭(chou)氧傳感器(qi)、臭(chou)氧控(kong)(kong)制器(qi)組成，維(wei)持腔體臭(chou)氧濃度(du)(du)恒定;溫度(du)(du)控(kong)(kong)制系(xi)統(tong)(tong)為(wei)實(shi)(shi)驗倉(cang)(cang)提供穩(wen)定的(de)溫度(du)(du)20℃~40℃，通過(guo)電熱絲加(jia)熱實(shi)(shi)現加(jia)熱。有熱電偶實(shi)(shi)時(shi)(shi)測量調節(jie);濕(shi)度(du)(du)控(kong)(kong)制系(xi)統(tong)(tong)溫度(du)(du)控(kong)(kong)制系(xi)統(tong)(tong)為(wei)實(shi)(shi)驗倉(cang)(cang)提供穩(wen)定的(de)濕(shi)度(du)(du)，通過(guo)通入(ru)蒸汽實(shi)(shi)現加(jia)濕(shi)。配備(bei)干濕(shi)球濕(shi)度(du)(du)計實(shi)(shi)時(shi)(shi)測量調節(jie)。試驗時(shi)(shi)，同時(shi)(shi)模擬出一定的(de)溫度(du)(du)、濕(shi)度(du)(du)、臭(chou)氧環(huan)境，觀察(cha)紡織品在其中(zhong)的(de)顏色(se)變化。通過(guo)對比進行色(se)牢度(du)(du)評級(ji)。
