| 摘 要： | 1.INTRODUCTIONIn modern papermaking of newsprint, pitch and stickies control draws more attention with higher proportion of mechanical pulp and second fibers in furnishes. The accumulation of colloidal substance in process could affect the production and products most introduced by wood containing pulp and sec-ondary fibers. Sources of in-process colloid were complex and extensive, including lignin, hydropho-bic extraction, coating, adhesive and other additives1-3]. Pitch was more seriou…

| Abstract: | In this paper, modal colloidal substances (MCS) were employed to study the effects of in-process colloid on the properties of newsprint. The adsorption of MCS on fibers and optical and physical properties of newsprint were both investigated with and without retention systems including agglomerating agent and flocculent. Results showed that MCS could be absorbed on the fibers without retention system, and retention systems could promote the MCS retention efficiency while the physical properties of sheets was affected by blocking the formation of hydrogen bonding between fibers and the surface tension of water and density of paper decreased |
