First, let’s take a look at this "National Hazardous Waste Directory"
That is, the waste generated during the production and use of water-based paint will not be classified as hazardous waste.
Water-based paint will be "delisted" from the hazardous waste list?
Paint coating
In this regard, it is not a bad thing that water-based paints are "delisted".
From a technical point of view, the advantage of water-based coatings is that VOCs emissions are reduced, but water-based coatings that belong to the scope of coatings are still chemicals.
The ingredients and oil-based coatings inside have not been qualitatively changed.
They still contain resins, pigments, fillers, and additives.
Agents, solvents, etc.
, these components are still harmful to the environment and the human body during the production process.
Tan Chunlei, secretary-general of the China Coatings Industry Association, once said that the pollution caused by paint to the environment not only comes from the paint itself, but also from the solvents used in the paint.
If VOCs are not properly treated, they will all volatilize into the atmosphere and cause pollution to the environment.
VOCs will also undergo chemical reactions under the influence of environmental factors to generate pollutants that are more toxic than the original, thus forming secondary pollution.
And this is only for water-based paints with high product quality.
Returning to the above-mentioned cottage water-based paints, under various conditions that do not meet the standards, the pollution caused by it may not be cleaner and healthier than oil-based paints.
In the case of being "delisted" by the "Catalogue", how to make water-based coatings more environmentally friendly has become a major issue that needs to be considered urgently.
The upsurge of water-based paint has not gone down.
A series of domestic policies aimed at environmental protection have made people inside and outside the industry full of confidence in the future of water-based paint, and there are constant remarks about "water-based paint spring has come".
But in the editor's opinion, whether water-based paint can really develop in a big way remains to be seen.
After all, there are still many areas that need to be improved.
