Abstract
DC60(11/04/56) วิธีป้องกันการเปลี่ยนเป็นสีเหลืองของพื้นผิวแผ่นเหล็กกล้าซึ่งหลังจากกำจัดชั้นออกไซด์ที่มีSi ของชั้นผิวแผ่นเหล็กกล้าโดยกัดกรดแผ่นเหล็กกล้าหลังอบอ่อนต่อเนื่องกัดกรดซ้ำล้างน้ำและทำให้ แห้งซึ่งคงสภาพพื้นผิวแผ่นเหล็กกล้าระหว่างการกัดกรดกับการกัดกรดซ้ำกับระหว่างการกัดกรดกับ ล้างน้ำดังกล่าวเป็นสภาพเปียกโดยควรผลิตแผ่นเหล็กกล้ารีดเย็นซึ่งป้องกันการเปลี่ยนเป็นสีเหลือง ของพื้นผิวแผ่นเหล็กกล้าหลังกัดกรดจากการทำการล้างน้ำดังกล่าวโดยน้ำทำความสะอาดที่ได้ลด ความเข้มข้นเหล็กไอออนให้ไม่เกิน20g/Lมีคุณภาพลักษณะภายนอกที่ดีพร้อมกับมีทั้งความสามารถ เคลือบสารรองพื้นขั้นแรกกับความทนทานการผุกร่อนหลังเคลือบ รูปที่เลือกใช้ไม่มี DC60(11/04/13) Method to prevent yellowing of steel plate surface after removal of oxide layer containing Si. of the surface layer of the steel plate by etching the steel plate after continuous annealing, repeated etching, washing with water and making dry, which preserves the steel plate surface between etching and repeat etching and during etching and Such water rinsing is preferably wet condition to produce cold rolled steel sheets which prevent turning yellow. of the surface of the steel plate after etching by washing it with the cleaning water that has reduced The iron ion concentration does not exceed 20g/L. It has good appearance quality and has both the ability First coat of primer with corrosion resistance after coating. There is no picture to choose from.
