Product Description

JSJ***1 is a kind of compunded room temprature phosphorization liquid, including various accelerant. Phosphorization film can meet China GB****7 standard. JSJ***1 stll can be used as coating layer which can enhance adhesive capability between products and coatings, also it is with good corrosion resistance performance. Compunded from: JSJ***1 bath solution JSJ***1A phosphorization agent JSJ***1B accelerant, JSJ***1C neutralizing agent Standard Process Flow: Degreasing-water washing-acid washing-water washing-surface conditioner-treatment-phosphorization-water washing-drying Bath solution ingredients(as ***0 liters) *water******0% of the total volume for the work liquid *Add ****0 Kg JSJ**1A into bath solution, and then slowly add ****4 Kg JSJ***1B, well mix round; *Add water into solution until it reaches the total volume; *Heat until the temprature reaches as required and test acidity; Increasement (**0 liters) Total Acidity: 1 point increasing when adding JSJ***1A **6 Kg Free Acid: 0.1 point decreasing when adding **0g***0g JSJ***1C neutralizing agent, Accelerant: 1 point increasing when adding **0g***0g JSJ***1B accelerant; Work liquid condition: Total acidity: ****0 points; Free acid: **3 points Notes: *More phosphorization film forming time if the free acid is lower than normal *Film thickness can not meet the standard if the free acid is higher than normal *Accelerant temprature: **3 points (1 point increasing when **0 g***0g added) *Work temprature: Normal temprature *Treatment time: ****5 minutes
