確定工作(zuo)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)范圍是選型(xing)(xing)的重要(yao)依據(ju)。每(mei)種橡(xiang)膠(jiao)(jiao)材質的O型(xing)(xing)圈(quan)都有其適(shi)宜的工作(zuo)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)區間。例如(ru)，丁腈橡(xiang)膠(jiao)(jiao)O型(xing)(xing)圈(quan)的工作(zuo)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)一(yi)般(ban)在(zai)-20℃至120℃；氟橡(xiang)膠(jiao)(jiao)O型(xing)(xing)圈(quan)可在(zai)-20℃至250℃的高溫(wen)(wen)(wen)(wen)(wen)(wen)環境下長期使(shi)用(yong)；硅橡(xiang)膠(jiao)(jiao)O型(xing)(xing)圈(quan)能(neng)在(zai)-60℃至200℃的寬溫(wen)(wen)(wen)(wen)(wen)(wen)域保(bao)持(chi)良好性能(neng)。若(ruo)工作(zuo)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)超出O型(xing)(xing)圈(quan)的適(shi)用(yong)范圍，橡(xiang)膠(jiao)(jiao)會加速老化、變(bian)硬(ying)或變(bian)脆，失去(qu)彈性。例如(ru)，在(zai)高溫(wen)(wen)(wen)(wen)(wen)(wen)蒸汽(qi)管道密封中，若(ruo)選用(yong)耐(nai)溫(wen)(wen)(wen)(wen)(wen)(wen)不(bu)足的丁腈橡(xiang)膠(jiao)(jiao)O型(xing)(xing)圈(quan)，很(hen)快就會因(yin)高溫(wen)(wen)(wen)(wen)(wen)(wen)老化而泄漏；在(zai)低(di)溫(wen)(wen)(wen)(wen)(wen)(wen)制(zhi)冷設(she)備(bei)中，不(bu)適(shi)合的O型(xing)(xing)圈(quan)材質可能(neng)因(yin)低(di)溫(wen)(wen)(wen)(wen)(wen)(wen)變(bian)硬(ying)而無(wu)法實現有效密封。因(yin)此(ci)，需根據(ju)設(she)備(bei)實際運行時的比較低(di)和**高溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)，選擇合適(shi)耐(nai)溫(wen)(wen)(wen)(wen)(wen)(wen)性能(neng)的O型(xing)(xing)圈(quan)。江蘇國產O型(xing)(xing)圈(quan)批發廠家
