管螺紋密封膠的優勢

  管螺紋密封膠具有粘接強度較高,抗老化性能好等特點,尤其適用于設備管道、陶瓷、金屬等工業產品。管螺紋密封膠相比溶劑基、特氟龍膠帶、密封油膏等密封類型更為先進。下面天津樂泰膠廠家就這幾種密封方式的優劣性與管螺紋密封膠進行對比。

  溶劑基:密封劑在固化過程中隨著溶劑的揮發,會產生大的收縮,結合部位必須被再次上緊,以便更好地填充當中的間隙。其通過摩擦和變形的組合來鎖緊組裝組件。

  特氟龍膠帶:在有動態載荷的情況下,容易造成夾緊力下降和密封部位泄露。動態載荷也可以加速部件蠕變,引起泄露。在上緊力矩過大的情況下,特氟龍膠帶的潤滑作用也很容易引起部件的損壞。此項應用需要專業的技巧來避免工件的損壞。

  密封油膏:此項應用需要非常好的經驗并有可能導致低的工裝效率。組裝時環境凌亂,經常需要再次組裝數次來100%的密封。
