防水膜

首先拆下门内板，将防水膜小心地分离，这样可以接触到门把手的背面。

First remove the door panel and carefully peel back the waterproofing sheet to gain access to the back of the door handle .

根据溶胀曲线和溶胀度的测定，研究防水膜吸收不同浓度溶液的能力和吸收溶液的速度。

According to the swelling degree of swelling curves and the determination to study the waterproof membrane solutions of different concentrations of absorption capacity and absorption rate of the solution .

Study on Gas Diffusion and Waterproof Layer of Air Electrode

聚四氟乙烯对空气电极防水透气膜性能的影响

The Effects of PTFE on Waterproof Layer of Air Electrode

结果表明：防水透气膜具有优异的电化学性能，空气电极的极化明显减小，电流密度由82mA/cm2提高到150mA/cm2；单电池样品的恒流放电容量在40Ah以上。

The results show that the polarization of air electrode is reduced greatly and the current density is increased from 82 mA / cm2 to 150 mA / cm2 . The capacity of the aluminum / air battery is over 40 Ah at 4A .

再生纤维素膜（甘蔗渣浆制）表面直接用紫外光固化聚氨酯－丙烯酸酯制备出防水性复合膜。

A composite film with water-resistance was prepared by curing polyurethane-acry-late on regenerated cellulose film ( from bagasse pulp ) under UV-irradiation .

防水粉憎水膜形成机理及稳定性的研究

On the formation mechanism and stability of waterproof powder hydrophobic film

同时还探讨了聚合物水泥防水涂料的成膜机理。

The film forming mechanism of polymer-cement waterproof coating was discussed as well .

在iPhone7底部钻孔不仅不能显示出隐藏的耳机接口，还会破坏手机的防水性能，因为防水要求手机底部小孔上覆盖的一层防水膜要完好无损。

Not only will drilling a hole into the bottom of the iPhone 7 not reveal a hidden headphone socket , but it will also ruin the waterproofing of the smartphone , which requires the membranes covering the holes in the bottom of the phone to be undamaged .
