What are the advantages of using water based paint?

Advantages of water-based paint:

1. Use water as a solvent to save a lot of resources; Eliminates the risk of fire during construction; Reduced pollution to the atmosphere; Only a small amount of low-toxicity alcohol ether organic solvent is used to improve the working environment conditions. Generally, the organic solvent of water-based paint (accounting for 5% of the coating) is between 5% and 15%, while the cathode electrophoretic coating has been reduced to the following, which has a significant effect on reducing pollution and saving resources.

2. Water-based coatings can be directly coated on wet surfaces and wet environments; It has good adaptability to the surface of the material and strong adhesion of the coating.

3. The coating tools can be cleaned with water, which greatly reduces the consumption of cleaning solvents and effectively reduces the damage to construction personnel.

4. The electrophoretic coating film is uniform and flat. Good flattening; The inner cavity, weld, edges and edges can be coated with a certain thickness of coating film, which has good protection; The electrophoretic coating has the best corrosion resistance, and the salt spray resistance of the thick film cathode electrophoretic coating can reach up to 1200h.

Water-based paint disadvantages:

1. Water-based coatings have high requirements for the cleanliness of the surface of the material during the construction process, because the surface tension of the water is large, and the dirt is easy to cause shrinkage porosity of the coating film;

2. The dispersion stability of water-based coatings against strong mechanical force is poor, and when the flow rate in the conveying pipeline changes sharply, the dispersed particles are compressed into solid particles, which makes the coating film pit. It is required that the conveying pipeline is in good shape and the pipe wall is free of defects.

3. Water-based coatings are highly corrosive to coating equipment, so anti-corrosion lining or stainless steel materials need to be used, and the equipment cost is high. The corrosion of water-based coatings on the transportation pipeline, the dissolution of metals, the precipitation of dispersed particles, and the pitting of the coating film, also need to use stainless steel pipes.

4. Baking water-based coatings have strict requirements for construction environmental conditions (temperature and humidity), which increases the investment in temperature and humidity control equipment and increases energy consumption.

5. The latent heat of water evaporation is large, and the energy consumption of baking is large. Cathode electrophoresis paint needs to be baked at 180 °C; Latex paints, on the other hand, take a long time to dry completely.

6. Organic co-solvents with high boiling points produce a lot of oil smoke during baking, which drops on the surface of the coating film after condensation and affects the appearance.

With the improvement of people's awareness of environmental protection and health, when carrying out home decoration, they tend to choose healthy and environmentally friendly water-based paint, which is the water-based paint construction process.

This water-based paint that uses water as a solvent not only saves resources and eliminates fire hazards during construction, but also has a strong coating adhesion.

All coatings that use water as a solvent or as a dispersion medium can be called water-based paint.

There are three types of water-based paints: water-soluble, water-dilugent, and water-dispersed (latex paints).

The problems to be paid attention to in the construction of water-based paint include:

1 Since the main component of water-based paint is water, the material used in the water-based paint circulation system must be stainless steel.

2. The general wood surface to be coated should be preliminarily sanded with 200 sandpaper and then sanded with 600 sandpaper to make it smooth and smooth. Joinery workpieces can be sanded directly with 600 sandpaper. Fine sandpaper sanding will make the wood grain tight and reduce the wood grain granulation.

3 Water has high electrical conductivity, so there is a big difference between the automatic spraying system used to spray water-based paint and spray solvent-based paint. In order to prevent high-voltage static electricity from leaking to the main circulation pipeline, the piston pump is used inside the water-based paint robot instead of the gear pump to disconnect the painting circuit from the main circulation pipeline to prevent danger.

4 winter construction indoor engineering should be carried out under heating conditions, the room temperature should be balanced, should not be lower than 10 degrees, and should not change suddenly, should be set up a special person responsible for measuring the temperature and opening and closing doors and windows, in order to facilitate ventilation and remove moisture, summer construction should be added to the paint white water, to prevent damp whitening. Water-based varnish construction should be kept ventilated. In summer, it is necessary to prevent mildew.

Water-based paint uses water as the solvent, which greatly reduces the fire hazard during construction. The application tools of water-based paints can be cleaned with water. The surface cleanliness of the water-based paint and the material during the construction process is very high.

This water-based paint is pollution-free, water-based paint is pollution-free, and it can be used after installation, and it can be used after installation.

It has little pollution to the environment and little harm to the human body.
