Abstract: The present invention relates to wooden powder on which calcium carbonate is attached, a manufacturing method thereof, and paper containing the wooden powder. Specifically, the present invention provides wooden powder on which on which calcium carbonate while polymers, wooden powder, and calcium carbonate are attached. If the method using polymer for producing wooden powder on which calcium carbonate is attached according to the present invention is utilized for producing paper, wooden powder which has a calcium carbonate containing rate which is remarkably high, an improved whiteness index, and improved strength in comparison with paper made of wooden powder on which calcium carbonate is attached by using a polymer. If the wooden powder of the present invention is utilized for producing paper, the whiteness index is higher than paper made of wooden powder bleached by expensive chemicals such as hydrogen peroxide, and a paper producing process can be simplified, and production costs for paper can be remarkably reduced as the usage amount of natural bleached pulps for improving the whiteness index of paper is reduced. [Reference numerals] (AA) Fiber materials for paper; (BB) Beating; (CC) Mixing White polymers; (DD) Producing paper; (EE) Wood powder; (FF) Adding calcium hydroxide; (GG) Combination of wooden powder and calcium hydroxide by a polymer; (HH) Injecting carbon dioxide; (II) Forming calcium carbonate wooden powder
Abstract translation: 本发明涉及其上附着碳酸钙的木粉，其制造方法和含有木粉的纸。 具体地说，本发明提供了一种木质粉末，其上附着有聚合物，木粉和碳酸钙的碳酸钙。 如果使用根据本发明的用于生产其上附着碳酸钙的木粉的聚合物的方法用于生产纸，具有显着高的含碳酸钙的速率的木粉，改善的白度指数和提高的强度 用通过使用聚合物附着碳酸钙的木粉制成的纸。 如果将本发明的木粉用于生产纸张，则白度指数高于用过氧化氢等昂贵的化学品漂白的木粉制成的纸，并且可以简化造纸过程，纸的生产成本可以 随着用于提高纸的白度指数的天然漂白纸浆的使用量减少，显着降低。 （附图标记）（AA）纸的纤维材料; （BB）殴打; （CC）混合白色聚合物; （DD）生产纸; （EE）木粉; （FF）加入氢氧化钙; （GG）由聚合物组合木粉和氢氧化钙; （HH）注入二氧化碳; （二）形成碳酸钙木粉
