Dosage Calculation of Epoxy Zinc-rich Primer and Paintable Area Per Kilogram

Ⅰ. How to calculate the amount of epoxy zinc-rich primer?

The paint budget, construction, acquisition, etc. are all very important. If you buy too little, you will not be able to use it, and you will delay the construction period. If you buy too much, it is often more troublesome to return, and it will even cause waste if you cannot return it. So, how to correctly calculate the amount of epoxy zinc-rich primer and more accurately estimate the amount of epoxy zinc-rich primer. How to calculate the amount of epoxy zinc-rich primer?

For example: the customer's construction area is 1000 square meters, the required dry film thickness is 50 microns, and the theoretical coating rate of our company's epoxy zinc-rich primer is 0.18kg/㎡/50 microns, so the dosage can be directly calculated as 0.18 ×1000=180kg, that is, an area of 1000 square meters can be used with 180kg of zinc epoxy primer.

The construction method selected is air spraying or airless spraying. The ratio of the diluent to the company is 10:1, which means that 18kg of diluent can completely solve the construction problem (this diluent ratio does not include gun washing and cleaning).

Ⅱ. How much area can be painted per kilogram of epoxy zinc-rich primer?

The theoretical coating rate of epoxy zinc-rich primer is 0.18kg/㎡/50μm, which means that more than 5㎡ can be brushed per kilogram. However, this is only a theoretical value, and there are several factors that affect the coverage rate of epoxy zinc-rich primers.

1. Solid content of epoxy zinc-rich primer

The content of epoxy zinc-rich primer can be customized, and the higher the zinc powder content, the greater the coating rate.

2. Construction substrate of epoxy zinc-rich primer

The roughness and shape of the substrate affect the coating area invisibly. The rougher the appearance, the more exotic the shape, the lower the coating rate.

3. The proficiency of the construction personnel of epoxy zinc-rich primer

The skill of the construction personnel is also one of the factors that affect the coating area of the epoxy zinc-rich primer. It is obvious that 50μm is to be painted. If you do not grasp the painting speed, it will affect the thickness of the paint film, and then affect the coating rate.

4. Construction method of epoxy zinc-rich primer

The epoxy zinc-rich primer can be applied by airless spraying, air spraying, brushing, roller coating, etc. Different construction methods have different painting areas.

Jinhai has passed the ISO9001 quality management system certification and CCS factory certification of China Classification Society. The main technical personnel of the company are all from national scientific research institutions, and they have been focusing on the development of coatings and paints in the field of heavy anti-corrosion for more than 20 years.
