橡膠軟管的安全事項

◆ 應注意膠(jiao)管(guan)的(de)(de)保存(cun)、使用和運輸中的(de)(de)維護(hu)，保持(chi)清(qing)潔(jie)和不受(shou)損(sun)壞。應避(bi)免膠(jiao)管(guan)受(shou)陽光(guang)照射、熱體烘烤、雨雪(xue)浸淋(lin)，防(fang)止酸、堿(jian)、油類及(ji)Y機(ji)溶劑等與膠(jiao)管(guan)接觸。與熱源距離應不小(xiao)于1m，橡膠(jiao)軟(ruan)管(guan)，存(cun)放(fang)溫度(du)應為-15℃。

◆ 氣(qi)(qi)焊（割(ge)）操作中為保證安全，復(fu)合橡膠(jiao)(jiao)軟管(guan)，與氧(yang)(yang)氣(qi)(qi)表高壓端相連的(de)氣(qi)(qi)瓶（氧(yang)(yang)氣(qi)(qi)管(guan)道）的(de)閥(fa)門應全開，以便(bian)在(zai)大量氧(yang)(yang)氣(qi)(qi)輸(shu)出時提供充(chong)足的(de)氣(qi)(qi)量和穩定的(de)壓力，防止在(zai)使用時壓力突然下降，發生回(hui)火并倒(dao)燃進入氧(yang)(yang)氣(qi)(qi)膠(jiao)(jiao)管(guan)而引起B炸。

橡膠(jiao)軟膠(jiao)管結構與用途

橡(xiang)膠油管常(chang)見(jian)不良現象

? 磨損(sun)/爆管：不利環境下劣化加速(su)

過度磨損(sun)導致外(wai)層橡膠脫(tuo)落，須立即更換

橡膠產品普遍(bian)均害怕紫(zi)外線、臭氧(yang)、水、高溫(wen)、摩擦，這些都加速其老化影響使(shi)用壽(shou)命。設備不免處(chu)于高溫(wen)高濕(shi)環境，工(gong)程機(ji)械露天存放均對軟管橡膠配方有了更高的(de)要求。因此，避(bi)免摩擦、過度彎(wan)曲、降(jiang)低彎(wan)曲頻率、避(bi)免高溫(wen)高濕(shi)、被C踏等是正解。
