At present, there are mainly five types of ultrafiltration membrane devices commonly used in industry: plate and frame type, tube type, spiral wound type, hollow fiber type,ptfe Tubular ultrafiltration membrane…

In addition to water pressure resistant sound-permeable membranes, another application of expanded polytetrafluoroethylene membrane in the field of consumer electronics is MEMS acoustic membrane. This applicati…

During the mass assembly of printed circuit boards for mobile phones, cameras and other acoustic devices, there are some technical issues that may jeopardize the integrity of MEMS acoustic films, including high…

There are two major periods of time each year when the air quality is relatively poor. One is the sandstorm and haze in spring, and the other is the high pollution haze days in autumn and winter. The period bef…
