Abstract
วิธีการผลิตผิวเคลือบเคมีฟอสเฟตบนผิวหน้าของเหล็กกล้าด้วยสารทำปฏิกิริยาที่ไม่มีการเติมสารออกซิไดซิง เช่น อิออนไนไตรด์หรือไฮโดรเจนเปอร์ออกไซด์ลงไปโดยตรง และจะมีอุณหภูมิอยู่ในพิสัยที่ไม่เกิน 40 องศาเซลเซียส มี pH อยู่ในพิสัยจาก 2.5 ถึง 4.5 และออกซิเดชั่น - รีดักชั่น โพเทนเซียลของสารทำปฏิกริริยา (ORP ในพจน์ของนอร์มอลไฮโดรเจนอีเลคโตรดโพเทนเซียส) ในพิสัยจาก 150 ถึง 550 mVสารทำปฏิกิริยาประกอบด้วยสารละลายในน้ำของ 2 องค์ประกอบคือ องค์ประกอบแรกคือ สารละลายกรดที่ประกอบด้วยอิออนของกรดออกโซ เช่น NO3- อิออนฟอสฟอริค (H3PO4 หรือ H2PO4-) และอิออนโลหะ เช่น Zn2+ เป็นส่วนมาก และองค์ประกอบที่ 2 คือสารละลายอัลคาไลน์ที่ประกอบ้ดวยอิออนไฮดรอกไซด์ (CH-) ที่เหมาะสมคือ สารทำปฏิกิริยาจะมีอุณหภูมิจาก 20 องศาเซลเซียสถึง 30 องศาเซลเซียส ค่า pH จาก 3.0 ถึง 4.0 และ ORP จาก350 ถึง 450 mV Method for producing chemical phosphate coatings on the surface of steel with no oxidizing agents such as ion nitride or hydrogen peroxide directly. And the temperature in the range does not exceed 40 ° C, pH in the range from 2.5 to 4.5 and oxidation-reduction potentiates of reagents (ORP in terms Of normal hydrogen electrode (potence) in the range from 150 to 550 mV.The reagent consists of aqueous solutions of two components: The first element is Acid solutions containing oxo-acid ions such as NO3-phosphoric ions (H3PO4 or H2PO4-) and metal ions such as Zn2 + are predominantly, and component 2 is an alkaline solution that Compound with appropriate ion hydroxide (CH-) is The reagent has a temperature of 20 ° C to 30 ° C, pH from 3.0 to 4.0 and ORP from 350 to 450 mV.
