I. characteristics of silicane pottery process
1. Environmental protection: environmental protection treatment agent replacing traditional phosphating
2. Environmental protection: compared with phosphating, silanization does not contain phosphorus and heavy metals, and the sewage is discharged in an environmentally friendly way. As long as the sewage treatment is slightly neutralized to pH = 7-9 and slightly precipitated or filtered, it can be discharged up to the standard.
3. Environmental protection: almost no slag. Compared with phosphating, phosphating slag produced by phosphating process is 200-300 times of that produced by ceramic process, and it is free of phosphorus and heavy metals, so it is easy to handle.
4. Energy saving: silane ceramic process is completely treated at room temperature (no heating in winter).
5. High efficiency: the treatment time of silane ceramic process is short, the spraying time is only ≥ 1min, only 1 / 3 of the phosphating process, and the surface adjustment process is not required, which can reduce the equipment investment
6. Cost saving: large treatment area, more than 120 ㎡ can be treated per kilogram of silanizer, and the use cost ≤ phosphating cost.


II. Applicable process conditions of silanization process
1. Applicable to spray pretreatment line
2. It is applicable to the pretreatment line of dip spray combination
3. It is applicable to the full immersion pretreatment line (the oil removal process needs to be equipped with ultrasonic)
4. It is suitable for manual or automatic soaking pretreatment of independent hanging device (ultrasonic is required for oil removal process)
5. Suitable for manual or automatic soaking tank type pretreatment line of galvanized sheet
6. It is not suitable for manual soaking pretreatment line of iron and steel
