Source principle of ceramic agent:

1. Zirconate precipitation crystal film: When the surface dissociated zrf6 - is dissolved in the metal ion fe2+and reaches the solubility product constant KSP, the zirconite precipitation will be formed.


2. Zirconic acid II dissociation:

h2zrf6+h+-zrf62-+2h+

Due to the sharp drop of H+concentration on the surface, the dissociation equilibrium of all layers of zirconium is shifted to the right, resulting in zrf6.

Nano ceramic agent


3. Nano-silicon promotes reaction acceleration:

[SI]: ZRO2+4 [H] - [zirconium]+2H2O

In the formula [Si] is a nano-silicon. [Zirconium], in order to reduce the product, nano-silicon dioxide is used as the reaction activator to accelerate the reaction speed, further leading to a sharp drop in the concentration of H+on the metal surface, resulting in the formation of [Zirconium] film nucleus.


4. Acid corrosion causes the reduction of H+concentration on metal surface: fe-2 e fe2+, 2 hours+2 e-2 [H]

fe2++ ZRF62-+H2O-FEZRF6+2H20

The zirconium salt deposit of the ceramic agent and water molecules form a film-forming material. For [zirconium], the film core continues to accumulate, the crystal core continues to grow into crystal particles, and countless particles deposit into a conversion film. Silane treatment and ceramic treatment can be called non-phosphorus membrane treatment, and there are other non-phosphate membrane treatment methods. These new technologies of ceramic chemicals have many similarities with silane or ceramic treatment. They generally contain trace or even no heavy metals and phosphates, and do not need to adjust the table top. They can process various plates, with short processing time, which can improve production efficiency, and have considerable advantages in energy conservation and emission reduction, Phosphorus-free film technology will become the main treatment of chemical conversion film on steel surface in the future.
