Nano-coating construction method for metal surfaces
The metal anti-corrosion nano-coating by spraying, brushing, rolling, dipping, etc. coated in the need for surface protection on the surface of the object, medium-temperature oven heating and drying curing.
☆ Pre-construction treatment
Before spraying, carry out surface treatment on the object to be coated, remove the residual paint film, rust, oil, oxidized skin and sundries on the surface, which is required to achieve no rust, no oil, no dust, no water marks.
The clean surface should be sprayed in time to prevent dust from returning.
Requirements for the construction environment without dust, exhaust devices or the corresponding air vacuum equipment to ensure the quality of construction
☆ Painting
It should be stirred well before use, and according to the requirements of various processing techniques, it can be coated in many different forms (such as brushing, spraying, dipping, etc.). Special needs can be coated more than two times.
Recommended air spraying method of construction: air pressure: 0.3-0.4MPa, spraying distance: 15-25cm, spray gun aperture 0.5-1.0MM recommended film thickness: 5-15 microns.
Ambient temperature: 10-30 °C, relative humidity: 45%-75%.
The cleanliness of the spray booth is within 10,000 levels, and the cleanliness of the leveling area and baking area is within 100,000 levels.
Drying temperature: 85 degrees baking table dry 30 minutes after 160-170 degrees oven or drying line baking 10min 1kg liquid coating area: spraying 300 square meters
