Abstract
พลาสติกที่เตรียมได้จากแป้งมันสำปะหลังดัดแปรโดยวิธีการหล่อในแม่แบบจะมีลักษณะและมีสมบัติ ต่างๆ ที่หลายหลาย ตั้งแต่มีลักษณะใส มีความยืดหยุ่นดี มีความทนต่อแรงดึงดี สามารถทำให้มีสีต่างๆ ได้โดยการ เติมผงสีเข้าไป จนถึงมีลักษณะโปร่งแสง มีความแข็งสูง ทั้งนี้แป้งมันสำปะหลังดัดแปรสามารถเตรียมได้จาก กระบวนการทางเคมี โดยใช้มาเลอิกแอนไฮไดรด์เป็นสารดัดแปร โซเดียมไฮดรอกไซด์เป็นสารเร่งปฏิกิริยา และ น้ำเป็นตัวทำละลาย การเปลี่ยนแปลงลักษณะและสมบัติต่างๆของพลาสติกข้างต้น สามารถทำได้โดยการเปลี่ยน แปลงปริมาณของมาเลอิกแอนไฮไดรด์ที่ใช้ในการดัดแปร The plastics prepared from cassava starch modified by the casting method in the template have different characteristics and properties ranging from clear appearance. Good flexibility Have good tensile strength Can be made into different colors by adding pigment powder. Until it looks translucent High hardness The modified cassava starch can be prepared from Chemical process By using maleic anhydride as a modified substance Sodium hydroxide is a catalyst and water is a solvent. Changes in characteristics and properties of the above plastics. Can be done by changing Convert the amount of maleic anhydride used in the modification.
