김성권,류훈,류재홍 ( Sung kwon Kim,Hoon Ryu,Jae Hong Ryu ) 한국공업화학회 1997 응용화학 Vol.1 No.1
This study was performed to investigate the retention(first-pass retention, solid and ash contents) and the cationic demand(CD) amounts according to the addition of various retention aids. For the purpose of this study, polyethyleneimine(PEI, SC) and polyacrylamide(PAM, NC, UN and SG) as a retention aids were used. De-inked pulp(100% DIP) and headbox stocks(containing headbox fines) obtained from de-inking process were treated with these retention aids. In the case of retetion, PAM treament was better than those of PEI(SC) treatment. On the contrary to the retention, PEI(SC) was greater than those of the other retention aids(NC, UN and SG-PAM) in the ability of anionic trash removal.

과산화수소 보존표백시 Silicate 대체 약품에 관한 연구
이상헌,정성욱,김성권,류재홍,Michalowski, R J 한국공업화학회 1997 응용화학 Vol.1 No.2
This study was carried out to investigate the effect of the Versenate PS as the peroxide bleach stabilizer in peroxide bleaching system. Currently, but, most peroxide bleach systems contain peroxide, caustic to activate the peroxide, and the use of a stabilizer such as sodium silicate to stabilize the peroxide during the actual bleaching. Therefore, to evaluate he degree to replace sodium silicate, the experiments of metal signature analysis, metal control by chelant(DTPA), caustic level optimization, and the addition of Versenate PS peroxide stabilizer were performed. The results shows that the only combination of Versenate PS and low sodium silicate provide the most effective peroxide bleaching.
