Abstract
การประดิษฐ์นี้เกี่ยวข้องกับเม็ดสี PCC นวัตกรรมใหม่ ซึ่งสามารถใช้ในสูตรผสมสารเคลือบ กระดาษ เพื่อผลิตกระดาษเคลือบ "อเนกประสงค์" โดยเฉพาะอย่างยิ่งสำหรับการใช้งานพิมพ์หมึกพ่น ซึ่งคุณภาพการพิมพ์ที่ได้เหมือนกัน หรือใกล้เคียงกันมากกับกระดาษให้ความคมชัดสูงที่มีจำหน่วยทั่ว ไป ในขณะที่ยังคงรักษาต้นทุนการผลิตกระดาษให้อยู่ในระดับต่ำ เม็ดสีดังกล่าว เตรียมได้จากกรรมวิธีคาร์บอเนชัน โดยใช้อัตราการไหล CO2/อากาศที่ลดลง ซึ่งนำไปสู่การได้กลุ่มก้อนอนุภาค PCC ชนิดรูพรุนที่มีโครงสร้างเฉพาะเจาะจง และมีคุณสมบัติพิเศษ โดยเฉพาะ ต่อจากนั้น เป็นขั้นตอนการทำให้เข้มข้นขึ้น ซึ่งนำไปสู่การได้กลุ่มก้อนอนุภาคที่เหมือน กันกับกลุ่มก้อนอนุภาคที่ได้ในขั้นตอนคาร์เนชันโดยส่วนใหญ่ แต่มีปริมาณของแข็งสูงขึ้น และมี ความเหมาะสมในการใช้งาน The invention involves innovative PCC pigments that can be used in paper coating formulations to produce coated papers. "Versatile" especially for inkjet printing applications. Which the print quality is the same Or very close to high definition paper with conventional memory while maintaining low cost of paper production. Such pigment Can be prepared from the carbonation process Using flow rate Reduced CO2 / air This leads to the specific structure of porous PCC particles. And has special properties. After that, it is the concentration process. Which leads to the formation of particle-like clumps Together with most particle clumps obtained in the carnation process But has a higher solid content and is suitable for use.
