 Use and recommend the use of technology: 
 The state of the workpiece to go to grease, mechanical polishing addition to December, to ensure that the surface is absolutely clean. 
 Passivation paste with a brush coated on the stainless steel surface, the time was 20min, until the light green is the end of said passivation. 
 (3) rinsing with water, wash the surface passivation paste. 
 4 Finally, the chloride ion content is less than 25PPM clean water (pure water or filtered water) soaked, rinsed 1-3min. 
 (5) drying. 
 Wastewater to focus on, plus the alkaline lime or sodium hydroxide, and PH value close to 7:00 before releasing no effect on the environment. 
 Typical process: 
 1, the oil - washing - pickling passivation - rinsing - drying 
 The effect of treatment: 
 One can keep the original color after cleaning the workpiece does not change the size of the workpiece to improve the surface quality. 
 (2) to improve the corrosion resistance of stainless steel, the passive film breakdown potential than that of untreated time can be increased by several hundred millivolts, and through the state's unified regulations "blue dot Law test, 30 seconds a blue dot. 
 Packing: 
 This product family is 25Kg, (1kg / bottle, 24 bottles / carton) packaging.
