Abstract
สเลอร์รีของยิปซัม จะรวมถึงแคลเซียม ซัลเฟต เฮมิไฮเดรท, น้ำ และ แคลเซียม ซัลเฟต ไดไฮเดรท จะถูกเคลือบด้วยสารที่กระจายตัวได้ชนิดไฮโดรฟิลิก สารเคลือบจะละลายได้น้อยกว่าแคลเซียม ซัลเฟต เฮมิไฮเดรท เพื่อหน่วงการเผยของ แลนด์ปลาสเตอร์ต่อส่วนที่เหลืออยู่ของสเลอร์รี ซึ่งจะป้องกันการทำให้ตกผลึกก่อนกำหนด และการทำให้แข็งก่อนเวลาที่กำหนดไว้ ซึ่งมาพร้อมกับมัน รูปลักษณะอื่น คือ สเลอร์รีของยิปซัม ซึ่งจะรวมถึงแคลเซียม ซัลเฟต เฮมิไฮเดรท, สารช่วยกระจายตัวชนิดโพลีคาร์บอกซิเลต, น้ำ และแคลเซียม ซัลเฟต ไดไฮเดรทที่ถูกเคลือบ ในกรณีนี้ , สารเคลือบที่กระจายตัวได้ชนิดไฮโดรฟิลิก จะถูกเลือกเพื่อใช้เป็นสารดัดแปลง เพื่อส่งเสริมความสามารถของสารช่วยกระจายตัวที่จะทำให้สเลอร์รีของยิปซัมกลายเป็น ของไหล Slurry of gypsum These include calcium sulfate hemihydrate, water and calcium sulfate dihydrate, and are coated with a hydrophilic dispersible agent. The coating is less soluble than calcium sulfate hemihydrate to delay the exposure of Land Plaster continues with the remainder of Slerry. Which will prevent premature crystallization And hardening before the specified time Which comes with it Another feature is the slurry of gypsum. This includes calcium sulfate hemihydrate, polycarboxylate dispersant, water and calcium sulfate dihydrate coated, in this case, hydrophilic dispersible coatings Lick Will be selected for use as a modified substance To promote the ability of dispersant to turn gypsum slurry into fluid
