Mini-Encyclopedia of Papermaking Wet-End Chemistry Additives and Ingredients, their Composition, Functions, Strategies for Use. TALC (for pitch control and as a filler). Composition: The chemical formula of pure talc is magnesium silicate,
Jan 17, 2013 Talc is well-known as talcum powder. It is a natural hydrated magnesium silicate H 2 Mg 3 (SiO 3) 4. Talc is a soft, low abrasive, flat-like particle, chemically inert and organophilic material. These are reason why many paper mill use this filler. commercially talcum powder is a wide range of mineral mixtures. Hence pure talc is difficult
Talc is best known to papermakers as a detackifier, and it is widely used in efforts to combat the effects of pitch and sticky materials in papermaking processes (Valero and Holton 1995; Trivedi 1997). However, talc is also widely used as a filler, especially in Finland, Japan, China, and France, where high-quality deposits are located (Biza 1999).
Feb 01, 2017 Five samples of talc with different particle size distribution have been chosen in order to understand their dispersion chemistry and the role of dispersed talc in papermaking. 2. Experimental2.1. Materials. The bleached mixed hardwood chemical pulp was collected from an integrated pulp and paper mill in north India.
KEYWORDS: Talc, Pitch, Stickies, Deposition, Agglo-meration, Papermaking SUMMARY: In the paper industry talc is frequently used to prevent deposition of pitch, consisting of a variety of organic compounds derived from tree resins forming colloidal micro-scopic droplets or particles in the wet circuit of a paper mill.
