Appearance introduction and influencing factors of ceramic chemicals

Appearance of ceramic coating: color film, golden yellow, purple, violet, blue

Influencing factors of color:

1. Acidity is pH value;

2. Temperature;

3. Time;

4. Sheet.

Judgment criteria of skin film:

1. No ash hanging;

2. No rust.

Nano ceramic agent

Role of skin membrane:

1. Corrosion prevention;

2. Improve the adhesion of paint film.

Methods for on-site testing of adhesion:

1. Impact test;

2. Cross cut test: 15mm × 15mm grid.

Corrosion resistance test of skin film: immerse in 3% NaCl solution at 12-25 ℃ for 15min, take out the sample to wash and dry (blow dry or dry with towel and filter paper), and visually inspect the rust (except for air, edge and corner). It is qualified if there is no obvious rust.

The use temperature of nano-ceramic agent is normal temperature - 30 ℃, and the treatment process produces almost no sediment. The slotting period is 6-12 months, the dosage of the preparation tank is 20-25 kg/t, the treatment area of each kilogram of concentrated solution is 120-150 m2, the treatment time is 5-10 minutes, the 3% salt water is soaked for 1 hour without rust, and the 5% salt spray test (with paint film, cross) is 480 hours.
