Polyimide film, also called polyimide film, is a kind of thin-film insulating material. It is mainly made of pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (DDE) in a strong polar solvent through polycondensation and casting to form a film and then imidization. Polyimide film generally appears yellow, but now it can be made into various colors, such as amber polyimide film, black polyimide film, red polyimide film, green polyimide film and transparent polyimide film.

Alternating current adapters convert the AC power from your wall outlet to a smaller voltage direct current power for your electronic device. They accomplish this in two steps, first scaling the voltage and then converting the AC to DC. There are many kinds of AC DC adapter with different models like 7.5W Max Wall Mounted Adapter, 13.5W Max Wall Mounted Adapter, 24W Max Wall Mounted Adapter, Interchangeable Adapter, 18W Max Wall Mounted Adapter, etc.

1. It relies on the pressure head of the measured medium to push the oval gear to rotate for measurement.
2. The larger the viscosity of the medium, the smaller the leakage from the gear and the metering air gap. Therefore, the larger the sticky skin of the medium to be measured, the smaller the leakage error, and the better it is for the measurement.http://www.jyflowmeter.com/ele....ctromagnetic-flow-me
