Water-in-water coatings contain many components, which are prone to mildew under the influence of humidity and temperature increase. Among them, organic polymers such as cellulose (natural macromolecule) and PVA are more susceptible to mold and deterioration, so anti-corrosion is long-term stability of coatings.

Product deterioration, odor, and thinning are problems caused by unfavorable anti-corrosion links. The following are cause analysis and production control measures:

The pesticide preservatives are antiseptic products that have a bactericidal effect and can extend the shelf life of pesticides. Pesticide preservatives can rapidly and irreversibly inhibit the growth of microorganisms after the preservatives are exposed to bacterial microbes, which can lead to the death of microbial cells. Therefore, it is widely used in the pesticide industry.

Formaldehyde has been identified by the World Health Organization as a carcinogenic and teratogenic substance. It not only has irritating effects on skin, eyes, mouth, pharynx, esophagus and stomach, but also causes low-temperature exposure, chronic respiratory diseases, nasopharyngeal cancer, menstrual disorders, pregnancy syndrome, neonatal chromosomal abnormalities and memory of adolescents. A decrease in intelligence, etc., can also cause death at high doses.

The water treatment agent includes a corrosion inhibitor, a scale inhibitor, a bactericide, a flocculant, a purifying agent, a cleaning agent, a pre-filming agent, and the like. In practical applications, a composite formulation of a water treatment agent or a combination of various water treatment agents is often used.

For industrial biocide, most of the use is still used in the maintenance of industrial production and industrial products, and we do not use much in daily life

Ceramic ink, as its name implies, is mainly used in ceramics. Although it has played a great role in ceramics, some problems often occur, especially in summer, and it is easy to appear fermentation and moldy deterioration, which reduces performance and affects use. The use of ceramic coating preservatives can change this situation.

The killing index requirements in the group standard: the log killing value should be ≥5.00 (suspension method), the killing log value should be ≥3.00 (carrier method), and the disinfection field test killing log value should be ≥1.00.

The test of antibacterial properties of textiles is divided into quantitative test methods and qualitative test methods, and quantitative test methods are the most important.

Coating preservative refers to a kind of additive that can inhibit the decay of microorganisms in coatings and prevent the coating from breaking and deteriorating. The coating materials contain moisture and nutrients, which are highly susceptible to bacterial contamination, which causes the latex paint to have reduced viscosity, corruption, gas production and breakage. Preservatives are effective in sterilizing and preserving, and can extend the storage and shelf life of the coating. Ensure that the paint does not deteriorate or smell during storage.
