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.
