摘要:
The invention relates to a method for improving papermaking or board making process. The method comprises forming a fibre stock, and leading the fibre stock to a headbox and feeding it to a wire to form a wet fibrous web. A at least one polysaccharide having 1,4-beta-anomeric configuration in linkages between saccharide units of the polysaccharide backbone or the main polysaccharide backbone is applied to the fibre stock after machine chest or on the wet fibrous web. The invention relates also to paper made by the method and to the use of polysaccharide.
摘要:
A composition comprising a compound mixture dissolved in water, the compound mixture comprising at least one chlorite salt at least one cyclodextrin; and at least one alkaline base; provided that the cyclodextrin is in an amount of 0.13 to 13 parts by mass for every 50 parts by mass of chlorite anion ClO2 -, and the alkaline base is in an amount of up to 13 parts by mass for every 50 parts by mass of chlorite anion ClO2 -; wherein the composition has a pH of at least 12.5. A process for forming the composition and process for treating suspensions of particles with the composition are also disclosed.
