Gas product can prevent dust, dirt or liquid from invading sensing head.Meanwhile, waterproof ventilated membrane can allow gas pass through thin film immediately, from
And guarantee that sensor response speed keeps constant, prevent measurement result from mistake occurring and postpones.Communication equipment aspect out of doors：Family
After outer communication equipment is mounted with waterproof ventilated membrane product, the pressure reduction being caused due to temperature change will no longer be constituted to apparatus casing
Negative effect because waterproof and breathable product can in ambient temperature and pressure change rapid equalisation housing external and internal pressure；
But conventional waterproof ventilated membrane feature is more single, and have add the raw materials such as poisonous plasticizer, environmental protection
Property is poor, and the range of ventilated membrane is less, and some impact strengths are low, is easily damaged, and some resistances to ag(e)ing are poor, service life
Short, therefore, the waterproofing membrane of research higher performance just seems particularly necessary；.
