1. 玻璃钢专用底漆 Special Primer for FRPAmount of the calculation

玻璃钢专用底漆 Special Primer for FRP Actual dosage and the shape of the workpiece, the construction method, the surface treatment method, the expected dry film thickness, and $ The gravity and bulk solid parts of玻璃钢专用底漆 Special Primer for FRPare highly correlated.

1. The parameters that need to be known first before determining the dosage:

Construction: the shape of the workpiece, the construction method, the surface treatment method, the expected thickness of the dry film.

Paint products: volume of solid parts, specific gravity.

2. Calculate the theoretical amount of epoxy zinc-rich primer.

With national standard 玻璃钢专用底漆 Special Primer for FRPfor example, the specific gravity is about 2.4kg / kg. The volume solid portion is about 66% (note that the bulk solid portion, not the mass solid portion, and not the zinc content, etc.).

The required dry film thickness is 50 μ m, then the theoretical coating rate is 5.5 ㎡ / ㎏; the theoretical dosage per square meter is 182g / ㎡; the coating rate calculation formula: (1000 * bulk solid) / (specific gravity * dry film thickness)

3. In the paint calculation tool, find out the corresponding loss coefficient, and you can know the actual dosage per square meter.

Large area: refers to the continuous large surface, such as the hull, deck, large boiler steel plate, etc.

Small area: refers to machine tools, large and medium-sized steel components, diameter above 80cm pipeline, etc.

4. According to the actual design film thickness, take the corresponding proportion to calculate the actual amount

If the film thickness is not given in the design, spray 40 μ m and 70 μ m.

For example, the user air spraying, plant steel structure, new steel, belong to the small area type, the required film thickness is 40 μ m, then found from the above table:

玻璃钢专用底漆 Special Primer for FRPThe actual dosage per square meter reference value: 0.232 kg / square meter, the area that can be coated per kilogram is: 4.3 square meters.
