Zindn shield cold spray zinc

01 ------ Introduction of zinc shield cold spray zindn

Zindn Shield high-performance cold-spray zinc coatings, cold-spray zinc products made of pure thin graphene, a new generation of heavy-duty anti-corrosion industrial paints. Deeply combining the high rust resistance of cold-sprayed zinc technology with the excellent electrical, chemical, and mechanical properties of graphene is an effective solution to the current anti-corrosion problems of steel structures.

04 ------Performance characteristics of zinc shield high-performance cold-sprayed zinc

1. Salt spray resistance:

The cold spray olefin zinc salt spray is far superior to the zinc-rich primers and graphene zinc powder primers containing more than 70% zinc on the market, and the salt spray resistance time is more than 2 times the existing zinc powder primer standard.

2. Excellent anti-cracking performance

The excellent mechanical strength of graphene is evenly dispersed into "graphene islands", which suppresses the propagation of cracks and extends the crack path.

Test method: Thick coating on angle steel to simulate steel structure, 50 cycles of cooling and heating between -20 and 60°C, cracking of primer without graphene (220-240 microns); primer of graphene (280-370 microns) ) No cracking.

3. Inhibit the spread of corrosion: The zinc salt deposits in the rusted area inhibit the spread of corrosion.

After 1000 hours of salt spray test, the corrosion of the traditional zinc-rich primer scratches spread.

In the salt spray test for 3000 hours, the rust of the cold sprayed zinc zinc primer did not spread.

4. Excellent adhesion: Graphene makes the coating have better adhesion.

5. Excellent impact resistance: The layer structure of graphene overlapping each other improves the impact resistance of the coating, impact resistance>55/cm.

6. Better economy: cold sprayed zinc zinc has high volume solid content, low density, and low paint consumption.

7. Better construction matching: the thick film does not crack or fall off, and the matching is better.
