Method.
Background technology
The anti-thin film of politef is that a kind of fluorine that employs replaces the synthetic macromolecule of all hydrogen atoms in polyethylene
Material.This material has antiacid alkali resistant, the feature of anti-various organic solvents, is practically insoluble in all of solvent.Meanwhile, waterproof
Ventilated membrane has resistant to elevated temperatures feature, and its coefficient of friction is extremely low, so after lubrication can being made, also become easy clean pot and
The preferable coating of water pipe internal layer；
Waterproof ventilated membrane is in a lot of sector applications widely: modern society's automotive operation is universal, can meet in transportation
To different weather and road conditions.Car light is externally exposed in environment all the time, and cloud, sleet, mince in road surface and dirt all can affect
The illumination of car light, thus affect the degree of safety of the driving process of vehicle.The rapid drawdown of external temperature can cause the decline of internal pressure,
Make equipment easily suck pollutant and increase fogging, ultimately cause car light fault.Waterproof ventilated membrane can provide persistently to car light
Protection, from the intrusion of external moisture, dust, greasy dirt and other dirts.The airing function that product is unique simultaneously is along with pressure
Change carries out respiratory exchange, thus reduces the pressure on sealing member, extends the service life of product.In terms of sensor device:
Waterproof and breathable product can effectively resist adverse effect produced by the pressure reduction that variations in temperature causes.Use the waterproof ventilated membrane can be
Rapid equalisation housing external and internal pressure when ambient temperature and pressure change, in gas sensor and electrochemical sensor, waterproof
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, apparatus casing will no longer be constituted by the pressure reduction caused due to variations in temperature
Negative effect because waterproof and breathable product can when ambient temperature and pressure change rapid equalisation housing external and internal pressure；
But the functional comparison of conventional waterproof ventilated membrane is 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.
