高分子液态密封胶(简称密封胶)是一种用于各种机械产品的接合端面及丝扣部位,防止设备三漏(漏水、漏气、漏油)的新型密封材料。由于它的作用与固体垫圈相似,故又称液体垫圈。它与固体垫圈相比具有如下优点:不需加工成形,可任意涂敷;不需压缩变形,无内应力、松弛和弹性疲劳等导致泄漏因素;有良好的粘附性,能充满接合面的凹陷和缝隙,避免界面泄漏;有高的内聚力和粘弹性,避免产生渗透泄漏和在剧烈震动冲击下产生破 Polymer liquid sealant (referred to as the sealant) is a new type of sealing material used to join the end face and threaded parts of various mechanical products to prevent the equipment from three leaks (water leakage, air leakage and oil leakage). Because of its role and solid gasket similar, it is also known as liquid gasket. Compared with solid washers, it has the following advantages: no processing and forming, can be applied at will; no compressing deformation, no internal stress, relaxation and elastic fatigue, leading to leakage factors; good adhesion, can be filled with the joint surface Sags and gaps to avoid interface leakage; high cohesion and viscoelasticity to prevent leakage and leakage under severe shock
