Definitions
- the invention relates to pulp and paper production and can be used in the production of paper, cardboard and other non-woven paper-like materials with intra-mass sizing with a starch binder.
- the described method is a development of the technology for producing starch binders and is based on a previously developed method for producing a binder for surface sizing of paper RU 2627373.
- the objective of the present invention is to create a simple method for producing a cationic starch binder for intra-mass sizing by simultaneous oxidation and cationization of natural starch in a continuous or batch mode, providing high productivity of the process and the ability to quickly regulate the concentration, viscosity and cationic charge of the target product.
- the problem is solved by simultaneous processing of natural starch with a solution of ammonium or sodium persulfate, as well as a solution of a cationic polyelectrolyte based on copolymers of acrylamide and a cationic comonomer based on acrylic acid or acrylamide (for example, dimethylamino-propylacrylamide) at elevated temperature to obtain a binder with a given concentration and viscosity and cationic charge.
- the processing process is carried out in a digester by simultaneously feeding starch of natural moisture, a solution of persulfuric acid salt with a flow rate of 0.2-2.5% by weight of absolutely dry starch, a solution of cationic polyelectrolyte with a flow rate of 1.5-5.0% by weight
- SUBSTITUTE SHEET (RULE 26) absolutely dry starch and, if necessary, water, followed by continuous or batch cooking at a concentration of starch suspension in the range of 4-16% and a temperature of 95-130 °C for 20-40 s for continuous cooking and 20-50 min for batch cooking, with further dilution with water to the required concentration.
- a technical result is achieved, which consists in obtaining and the possibility of easy and prompt regulation of the properties of the target product, ensuring its specified characteristics due to the possibility of quickly changing controlled process factors: dry starch consumption, oxidizing agent consumption, cationizing agent consumption, water consumption, temperature cooking, cooking duration.
- Natural starch with a moisture content of 12% is processed at a temperature of 130 °C in an automatic continuous cooking unit with a solution of ammonium persulfate with a concentration of 20% with a consumption of 0.28% by weight of absolutely dry starch, as well as a solution of cationic polyelectrolyte with the trade name Praestafix 1250 in commercial form with consumption of 4.4% by weight of absolutely dry starch, with the addition of water based on cooking a suspension with a concentration of 15.0%.
- the cooking duration is 30 seconds and is determined by the design of the heat exchanger of the cooking unit.
- the starch binder is diluted with water to a concentration of 2% and has the following parameters: viscosity according to VZ-2 - 52-55 s, cationic charge of the sample diluted with distilled water in a ratio of 1:10 - 85-90 mEq/l.
- Natural starch with a moisture content of 12% is treated in a batch digester with ammonium persulphate solution
- SUBSTITUTE SHEET (RULE 26) concentration of 20% with a consumption of 0.2% by weight of absolutely dry starch, as well as a solution of cationic polyelectrolyte with the trade name Praestol 644 BC with a concentration of 0.15% with a consumption of 2% by weight of absolutely dry starch, with the addition of water based on cooking the suspension with a concentration of 4 % at 93 °C. Cooking time is 30 minutes.
- the starch binder is diluted with water to a concentration of 2.5% and has the following parameters: viscosity according to VZ-2 - 60-63 s, cationic charge of the sample diluted with distilled water in a ratio of 1:10 - 92-97 mEq/l .
Abstract
L'invention concerne un procédé de production de liant cationique à base d'amidon pour le collage dans la masse de papier, et se rapporte à la production de papier, de carton, et de matériau assimilés au papier. Le résultat technique consiste en la possibilité d'obtenir un produit cible et d'ajuster facilement et fonctionnellement ses propriétés afin de garantir ses caractéristiques données grâce à la possibilité de changer rapidement les facteurs de commande du processus: consommation d'amidon en poudre, consommation d'oxydant, consommation d'eau, température de chauffe, durée. Ce processus de traitement est réalisé dans un autoclave en traitant simultanément l'amidon avec l'humidité naturelle, une solution de sel d'acide sulfureux selon une concentration de 0,2-2,5 % par rapport à la masse d'amidon complètement sec, une solution de polyélectrolyte cationique selon une concentration de 1,5-5,0 % par rapport à la masse d'amidon complètement sec et, si nécessaire, de l'eau, suivi d'un chauffage continu ou périodique à une concentration de suspension d'amidon dans une plage de 4-16% et à une température de 95-130°C pendant 20-40 secondes pour le chauffage continu et de 20-50 minutes pour le chauffage périodique, après quoi on effectue une dilution avec de l'eau jusqu'à obtenir la concentration voulue.
