The mildew and corruption of water-based paint, its causes and scientific treatment!

Lead

Water-based industrial coatings have become the main development direction of the coating industry at home and abroad

1.

Mildew, after opening the can, the water-based paint will show mildew spots on its surface due to the action of mold

Corruption, abnormal smell due to the action of bacteria, accompanied by flocculation, precipitation and other phenomena

Mildew and decay are caused by the combined action of rot and mold to make the water-based paint have a strong peculiar smell, accompanied by blackening, precipitation, flocculation, and agglomeration

Second, let's take a look at the factors that affect the corruption of water-based coatings

There are five conditions that determine the survival and reproduction of molds and bacteria, namely temperature, moisture, oxygen, bacterial species, and pH

Third, mildew, scientific approach corruption which water-based paint
.

1.
Mildew generally occurs on the interface between the water-based paint and the air layer.
Local mildew or mildew spots are formed on the surface of the water-based paint, and the internal appearance of the water-based paint does not change
.
Generally, open the can to remove the mildew spots or mildew spots on the surface of the water-based paint, then pour it into the paint mixing tank and add quick sterilization and preservatives while stirring, and stir for 30 minutes at 500-700 r/min.
Just repack it
.
If large mold spots appear on the surface of the water-based paint after opening the can, a small amount of emulsion and related additives must be added after the pre-treatment as described above
.

2.
Stirring detection
.
The spoiled water-based paint is sampled and inspected after mixing at a medium speed
.
The degree of demulsification of the emulsion after the action of bacteria is judged by detection
.
Generally speaking, the performance of internal wall water-based paint has little change, and external wall water-based paint can maintain strong anti-aging performance
.

3.
Add anti-mildew and preservatives
.
Add a quick bactericide at a ratio of 1:1000 or 1.
5:1000, and then add preservatives
.
First of all, this kind of rapid bactericide must have a deodorizing function; secondly, it must have a good bactericidal function, and secondly, the antibacterial function is considered
.
The selection of anti-mildew and preservatives must also have gas and liquid phase sterilization functions
.
Because the production of mold is carried out on the interface of gas and liquid (water-based paint), while the production of rot is carried out in the liquid (water-based paint)
.
Anti-mold and antiseptic bactericides with gas and liquid phase sterilization functions can simultaneously kill mold and rot in both gas and liquid phases
