Abstract

ผิวด้านในของปฏิกรณ์โพลีเมอไรเซชั่นจะถูกเคลือบด้วยสารละลายสำหรับการเคลือบที่มีโรซินที่ได้ดัดแปลง เมื่อส่วนประกอบโมโนเมอร์ที่มีไวนิลคลอไรด์เป็นหลัก โพลีเ มอไรซ์ในปฏิกรณ์ที่ได้รับการเคลือบดังกล่าว การเกิดเป็น ส่วนเกาะติดของโพลีเมอร์บนผิวด้านในของปฏิกรณ์จะลดลงไปเป็น อย่างมาก The inner surface of the polymerization reactor is coated with a coating solution containing modified rosin. When the vinyl chloride-based monomer is the primary polymers in the coated reactor, the adhesion of the polymer on the inner surface of the reactor is reduced. Down to a lot
