抗滲性是橡膠氣囊的重要功能之一。橡膠在一定壓力下阻塞空氣通道的能力。氣壓越高,防氣性能越好。

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.
所有能夠成膜的橡膠安全氣囊都不具有儲氣功能,因爲一些聚合物含有親水性基團。

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親水性基團,這些親水性基團對水分子的親和力大于水分子之間的氫鍵力,從而破壞了水分類聚合物材料的儲氣功能,例如聚醋酸乙烯乳液的塗膜在水之後是一種白色現象,即水分子穿透聚合物的內部。

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.

合並時間是從橡膠被激活到失效的時間。在使用雙組分橡膠之前,需要將兩種組分充分混合並攪拌至平均,並且兩種組分經曆必要的化學反應,最終成爲交聯的三維結構橡膠。合並時間是指從組分的化學反應開始到失去構造功能的時間。超過這個時間,橡膠的構造已經成爲一個問題,並且橡膠的各種功能指標不能得到有效保證。

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.

施工前應均勻攪拌膠球,特別是雙組分反應膠球。塗層施工完成後,會逐漸交叉連接形成薄膜。有些溶劑或氣體不能完全排出,在使用過程中會逐漸蒸發,造成橡膠體積和尺寸的變化。橡膠會産生很強的內應力。在長期的內應力作用下,會産生材料。加速老化、開裂,甚至失去防氣功能。熱膨脹率是一項技術性能指標,用來確定橡膠在受熱後的形狀變化。

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.
