Abstract: Carbon electrodes have been successfully synthesized and characterized for desalination system based on Capacitive Deionization (CDI) technology. The carbon electrodes were synthesized with an activated carbon (700 – 1400 m²/g), carbon black, glutaric acid and polyvinyl alcohol as a binder using cross-linking method at 120 °C. The study was to investigate salt removal percentage value of 0.1 M NaCl, MgCl and KCl using CDI cell. A solution with 0.1 M was supplied to the cell using a Boyu Submersible pump (model SP-601) at a flow rate of 10 mL/min. When potentials of 1.0, 2.0, and 3.0 V were applied to the CDI cell, the result showed that a solution of 0.1 M KCl has greater salt-removal percentage than the solutions with 0.1 M NaCl and MgCl. The salt-removal percentage of KCl was achieved at 55% for 3.0 V whilst resulted in 20 and 30% for NaCl and MgCl, respectively.

Abstract: Recently flexography develops faster and faster. The fine degree and the speed for making plate is asked to be higher. Flexographic cyrel digital imager (CDI) can meet the requirements. This article analyzes briefly to the parameters of making plate of CDI. The parameters for affecting the flexographic printing can be ensured. And the correct exposure time is made for making plate. Results show that the quality control is a systematic process. When printing different production, different screen lines, exposure parameters are adopted. By controlling the exposure time, the dot gain can be controlled effectively.
