Abstract
สารเหลวที่ทำขึ้นรวมทั้งน้ำ, อย่างน้อยโดยน้ำหนัก 50% แคลเซียม ซัลเฟต เฮมิไฮเดรต และตัวทำกระจายเฉพาะ โพลิคาร์บ็อกไซเลต ที่จัดเตรียมขึ้นโดยใช้อย่างน้อยหน่วย ทำซ้ำ 3 หน่วย หน่วยทำซ้ำหน่วยแรกเป็นชนิดไวนิลอีเธอร์ หน่วยทำซ้ำหน่วยที่สองรวมทั้งหน่วย ทำซ้ำชนิดกรดมาเลอิค หน่วยทำซ้ำหน่วยที่สามรวมทั้งหน่วยทำซ้ำชนิดกรดอะคริลิค/ ตัวทำกระจายโพลิเมอร์ มีน้ำหนักโมเลกุลจากตั้งแต่ 20,000 ถึง 80,000 แดลตัน/สารเหลวที่ทำจาก องค์ประกอบนี้ สามารถผลิตได้ที่ระดับน้ำที่ลดลง เพื่อเร่งการแห้ง และลดต้นทุนในการทำให้แห้ง The liquefied substance includes water, at least 50% by weight, calcium sulfate, hemihydrate and dispersant Polycarboxylate That is prepared using at least 3 repeating units. The first repeating unit is a vinyl ether type. The second repeat unit, including the unit. Reproduces the maleic acid type. Third repeating unit, including acrylic acid repeating unit / polymer disperser. Its molecular weight ranges from 20,000 to 80,000 Daltons / liquids made from This element Can be produced at lower water levels To accelerate drying And reduce the cost of drying
