Abstract
DC60 (16/09/41) การประดิษฐ์นี้เกี่ยวข้องกับสารผสมของสารขัดถูสำหรับซับสเทรทที่เป็น ตัวกลาง สำหรับบันทึกด้วยแม่เหล็ก ซึ่งอย่างน้อยมีสารขัดถู สารช่วยของสารขัดถูและน้ำ สารช่วยของสารขัดถูประกอบด้วย แอลิแฟทิค ออร์แกนิค ซัลเฟท, ออกซิแอลคิลีน แอลคิล อีเธอร์ ซัลเฟท หรือสารลดแรงตึงผิวชนิดแอมโฟเทอริค, และสารผสมของสารขัดถูนั้นมี พีเอช 1 ถึง 13 การประดิษฐ์นี้เกี่ยวข้องกับสารผสมของสารขัดถูสำหรับซับสเทรทที่เป็นตัวกลาง สำหรับบันทึกด้วยแม่เหล็ก ซึ่งอย่าง น้อยมีสารขัดถู สารช่วยของสารขัดถูและน้ำสารช่วยของสารขัด ถูประกอบด้วย แอลิแฟทิค ออร์แกนิค ซัลเฟท, ออซิแอลคิลีน แอลคิล อีเธอร์ ซัลเฟท หรือสารลดแรงตึงผิวชนิดแอมโฟเทอริค และสารผสมของสารขัดถูนั้นมีพีเอช 1 ถึง 13 DC60 (16/09/41) This invention involves a mixture of abrasive compounds for the substrates as a magnetic recording medium. Which at least contains abrasive substances Auxiliary agent of abrasive and water The abrasive auxiliaries contain organic aliphatic sulfates, oxylchylene, alkyl ether sulfate or ampoule-type surfactants. Teric, and abrasive mixtures contain pH 1 to 13. The invention involved an abrasive mixture for an intermediate substrate. For magnetic notes which at least contain abrasives. Abrasive and water auxiliaries The abrasive auxiliaries are composed of organic aliphatic sulfates, oxylkylene alkyl ether sulphates or substances. Reduce the surface tension of type amphoteric. And the abrasive mixture contains pH 1 to 13.
