Product Details

1. Overview
WX-F8302 ceramicizing agent is a phosphate-free reactive pretreatment chemical, mainly composed of zirconium salt, which can be converted at room temperature without surface adjustment and promoter, with less dosage and no sediment. The process is a reactive treatment, suitable for the surface treatment of cold plate, can form a dense single molecule water repellent film on the surface of metal materials, has excellent binding force with the coating, and can help the coating resist water vapor and salt spray on the base metal erosion, improve the anti-corrosion performance of the coating.

2. method of use
Process conditions: spray, dip
Process flow: degreasing-washing-ceramic-washing-drying
Tank distribution: first add tap water to 80% of the treatment tank, then add calculated amount of WX-F8302 certifier, and add certifier to adjust PH value.

3. process parameters
With slot: 2-3%
Temperature: normal temperature
Time: 2-5 minutes
Ceramic film appearance: colorless, light yellow, light blue, golden yellow, rainbow color
pH: 4.5-5.2
Pottery points: 18-28
Detection method:
pH value: with precision pH test paper or pH meter detection;
Pottery point: 2ml of working liquid is taken, injected into conical flask, 20 ml of water is added with pottery buffer solution and 5ml of pottery masking agent, 3 drops of pottery indicator are added, heated to above 90 ℃, titrated with pottery standard solution, the solution changes from purple to bright yellow as the end point, and the number of ml of standard solution consumed by titration multiplied by 5 is the number of pottery points of this liquid.

Advantages of 4. and phosphating
1, save the cost, the process is simpler, the table adjustment process can be saved not to use;
2, no sediment, do not need to clean, the nozzle will not be blocked;
3, no phosphorus, environmental protection;
4, can significantly improve the adhesion of paint and metal, prolong the corrosion resistance of metal time;

5. use and maintenance
1, each shift analysis of the parameters of the bath liquid, according to the parameters to add ceramic agent;
2. When the pottery point and pH value are low, add pottery agent to adjust in time; When the pH value is not within the range after adding the pottery agent, the pottery adjusting agent shall be added;
3. Add 1KG of WX-F8302 certifier to each ton of tank and raise 1 certifier point.
4. According to the number of workpieces to be processed or contaminated, it is recommended to replace the bath solution every 3-6 months.

6. considerations
1. Parameters of equipment and working fluid;
2. Clean the grease, oxides and stains attached to the surface of the workpiece, and regularly clean the sediment at the bottom of the tank;
3. The time interval between the completion of pottery and painting shall not exceed 16 hours;
4. The operator should wear safety protective equipment. If the liquid medicine contacts the skin or eyes, it should be rinsed with clean water immediately. In severe cases, it should be treated.
