Abstract: Provided are a liquid crystal polymer (LCP) film and a laminate comprising the same. The LCP film has a first surface and a second surface opposite each other, and a ratio of a ten-point mean roughness relative to a maximum height (Rz/Ry) of the first surface is from 0.30 to 0.62. By controlling Rz/Ry of at least one surface of the LCP film, the peel strength of the LCP film stacked to a metal foil can be increased, and the laminate comprising the same can still maintain the merit of low insertion loss.

Abstract: A system and a method for treating salt-containing glycerin wastewater are provided, wherein the system for treating the salt-containing glycerin wastewater includes a mixing tank, a filtering device, a distillation column, and a water supply device. The mixing tank is adapted to mix salt-containing glycerin wastewater with a concentrated hydrochloric acid to obtain a mixture. The filtering device communicates with the mixing tank and filters the mixture to obtain an acidic filtrate and a precipitated salt. The distillation column communicates with the filtering device and receives the acidic filtrate from the filtering device. The water supply device supplies water to the acidic filtrate. The system and method for treating the salt-containing glycerin wastewater can effectively recycle hydrochloric acid.
