抗渗性是橡胶气囊的重要功能之一。橡胶在一定压力下阻塞空气通道的能力。气压越高,防气性能越好。

   Impermeability is one of the important functions of rubber air bag.The ability of rubber to block air passages at a given pressure.The higher the air pressure, the better the anti-air performance.
   所有能够成膜的橡胶安全气囊都不具有储气功能,因为一些聚合物含有亲水性基团。

   All membrane-forming rubber airbags do not store energy because some polymers contain hydrophilic groups.

有些聚合物分子中含有亲水性基团,这些亲水性基团对水分子的亲和力大于水分子之间的氢键力,从而破坏了水分类聚合物材料的储气功能,例如聚醋酸乙烯乳液的涂膜在水之后是一种白色现象,即水分子穿透聚合物的内部。

   Some polymer molecules contain hydrophilic groups, and the affinity of these hydrophilic groups to water molecules is greater than the hydrogen bond force between water molecules, thus damaging the storage capacity of water-classified polymer materials. For example, the coating film of polyvinyl acetate emulsion is a white phenomenon after water, that is, water molecules penetrate the interior of the polymer.

合并时间是从橡胶被激活到失效的时间。在使用双组分橡胶之前,需要将两种组分充分混合并搅拌至平均,并且两种组分经历必要的化学反应,最终成为交联的三维结构橡胶。合并时间是指从组分的化学反应开始到失去构造功能的时间。超过这个时间,橡胶的构造已经成为一个问题,并且橡胶的各种功能指标不能得到有效保证。

   The merge time is the time from rubber activation to failure.Before the use of two-component rubber, the two components need to be fully mixed and stirred to the average, and the two components go through the necessary chemical reaction, and finally become a cross-linked three-dimensional structure of rubber.The combination time refers to the time from the chemical reaction of components to the loss of structural function.Beyond this time, the construction of rubber has become a problem, and rubber's various functional indicators can not be effectively guaranteed.

施工前应均匀搅拌胶球,特别是双组分反应胶球。涂层施工完成后,会逐渐交叉连接形成薄膜。有些溶剂或气体不能完全排出,在使用过程中会逐渐蒸发,造成橡胶体积和尺寸的变化。橡胶会产生很强的内应力。在长期的内应力作用下,会产生材料。加速老化、开裂,甚至失去防气功能。热膨胀率是一项技术性能指标,用来确定橡胶在受热后的形状变化。

   Before construction, the rubber ball should be mixed evenly, especially the two-component reaction rubber ball.After the coating is finished, it will gradually cross connect to form a film.Some solvents or gases can not be completely discharged, in the use of the process will gradually evaporate, resulting in rubber volume and size changes.Rubber produces a strong internal stress.Materials are produced under long-term internal stress.Accelerate ageing, craze, lose prevent qigong energy even.Thermal expansion rate is a technical performance index used to determine the shape change of rubber after heating.
