Abstract
วัตถุประสงค์ของการประดิษฐ์นี้คือเพื่อจัดเตรียมกรรมวิธีเพื่อการทำให้ได้มาซึ่งวัสดุแคลเซียม คาร์บอเนทที่ประกอบรวมด้วย GCC และ PCC ที่มีเศษส่วนย่อยของอนุภาคที่ละเอียดกว่า 1 ไมโครเมตรมากกว่า 80%, ถ้าจะให้ดีคือมากกว่า 85%, ถ้าจะให้ดีมากกว่านั้นคือมากกว่า 90% และ ถ้าจะให้ดีมากกว่านั้นอีกคือมากกว่า 95% และมีพื้นที่ผิวจำเพาะ น้อยกว่า 25 ม.2/ก. ในลักษณะ ที่ประหยัดค่าใช้จ่าย ที่ซึ่ง GCC และ PCC จะได้รับการบดร่วมกัน โดยอาจเป็นไปได้ว่ามีวัสดุแร่อีก อย่างน้อยที่สุดหนึ่งชนิด วัตถุประสงค์อีกประการหนึ่งของการประดิษฐ์นี้คือวัสดุแคลเซียมคาร์บอเนทจากการบด ร่วมกันในรูปของสารแขวนลอยชนิดเอเควียสและในรูปของผลิตภัณฑ์แห้ง วัสดุประสงค์อีกประการหนึ่งของการประดิษฐ์นี้คือการใช้ผลิตภัณฑ์ดังกล่าวในภาคการใช้ วัสดุแร่ใดๆ และที่เด่นชัดคือในอุตสาหกรรมกระดาษ, สีทาและพลาสติก The purpose of this invention is to prepare a process for obtaining calcium materials. Carbonates made up of GCC and PCC with sub-fractional fractions greater than 1 μm greater than 80%, preferably over 85%, preferably greater than 90%. Even better, more than 95% and a specific surface area of less than 25m2 / g in a cost-effective manner where GCC and PCC are ground together. It is possible that there is another mineral material. At least one of a kind Another purpose of this invention is calcium carbonate materials from grinding. Together in the form of an AKVI suspension and as a dry product. Another purpose of this invention is its use in any mineral material sector and, most notably, in the paper, paint and plastics industries.
