Nov. 23, 2017 - Archroma, a colour and specialty chemicals company, has introduced Cartaspers PLH liquid, a one-product, organic additive that delivers “easy and highly-effective” control of pitch and stickies deposition in soft water pulp and papermaking environments.

According to the company, pulp mill tests already report easier application, better performance and significant cost savings compared to alternative deposit control systems. Pitch, occurring from natural resins in virgin pulp, and stickies in recycled paper fibres, pose a challenge to pulp and paper producers because of their negative influence on papermaking productivity and paper quality. Archroma estimates packaging and tissues machines lose the equivalent of 4 per cent of their output per day due to machine contamination and sheet breaks caused by deposits, contributing to holes in the sheet, specks and printability issues, in addition to causing machine downtime and cleaning time. The anionic pale yellow, low viscosity liquid helps to passivate contamination and prevent agglomeration and deposition, without any impact on cellulosic material, explains Archroma. Cartaspers PLH liquid is suitable for use with brown stock and can be applied throughout the pulping process, as a washing aid or to passivate remaining particles in finished pulp.
