1.2 Chemical Properties
Bi ethers are highly alkaline and can neutralize and react with acidic substances. In addition, bisethers also have good thermal and chemical stability, and can remain stable over a wide temperature and pH range.
2. The mechanism of action of bis-(2-dimethylaminoethyl) ether
The mechanism of action of bis ether in anti-mold coatings mainly includes the following aspects:
2.1 Inhibiting mold growth
Diesel ethers inhibit the growth and reproduction of mold by destroying the integrity of mold cell membranes. Specifically, bisethers can interact with lipids and proteins on the cell membrane of mold, causing the cell membrane to rupture, cell contents to leak, and ultimately leading to the death of mold.
2.2 Inhibition of mold metabolism
Diesel ethers can also inhibit the metabolic process of mold, especiallyIn particular, it inhibits the respiration and energy metabolism of mold. By inhibiting the metabolism of mold, bis ether can effectively reduce the activity of mold and extend the service life of anti-mold coatings.
2.3 Inhibiting the formation of mold spores
Diesel ethers can also inhibit the formation and diffusion of mold spores. Mold spores are the main way for mold to reproduce. Inhibition of spore formation and diffusion can effectively prevent the spread and spread of mold.
III. Product parameters of bis-(2-dimethylaminoethyl) ether
The application of bis ether in anti-mold coatings needs to be selected and adjusted according to specific product parameters. The following are common product parameters of bis ether in anti-mold coatings:
| parameters | value |
|---|---|
| Active ingredient content | Above 95% |
| pH value | 8-10 |
| Temperature range | 0-50°C |
| Using pH range | 5-9 |
| Recommended additions | 0.5-2% |
| Storage Conditions | Cool, dry, ventilated |
IV. Application cases of bis-(2-dimethylaminoethyl) ether in anti-mold coatings
4.1 Construction anti-mold coating
In architectural anti-mold coatings, the amount of bis ether is usually 0.5-1%. By adding bis ether, building anti-mold coatings can maintain anti-mold effect for a long time in humid and high temperature environments, effectively preventing the growth and reproduction of mold.
4.2 Furniture anti-mold coating
In furniture anti-mold coatings, the amount of bis ether is usually 1-1.5%. By adding bis ether, furniture anti-mold coatings can maintain anti-mold effect for a long time in a humid and airtight environment, effectively preventing the growth and reproduction of mold.
4.3 Ship anti-mold coating
In marine anti-mold coatings, the amount of bis ether is usually 1.5-2%. By adding bis ether, ship anti-mold coatings can maintain anti-mold effect for a long time in a high temperature, high humidity and high salt environment, effectively preventing the growth and reproduction of molds.
V. Long-term protective effect of bis-(2-dimethylaminoethyl) ether
The long-term protective effect of bis ether in anti-mold coatings is mainly reflected in the following aspects:
5.1 Long-term anti-mold effect
Bis ethers can maintain anti-mold effect for a long time, usually up to more than 5 years. Through long-term anti-mold effect, bis ether can effectively extend the service life of anti-mold coatings and reduce maintenance costs.
5.2 Broad-spectrum anti-mold effect
Diethers have a broad-spectrum anti-mold effect on a variety of molds, including Aspergillus niger, Penicillium, Trichoderma, etc. Through the broad-spectrum anti-mold effect, bis ether can effectively prevent the growth and reproduction of various molds.
5.3 Environmental Friendliness
Diethers are environmentally friendly and will not cause pollution to the environment. Through environmental friendliness, bis ethers can meet modern environmental protection requirements and are widely used in various anti-mold coatings.
VI. Precautions for the use of bis-(2-dimethylaminoethyl) ether
When using diether, you need to pay attention to the following aspects:
6.1 Safe Operation
Di ethers have a certain degree of irritation. Protective gloves, masks and other protective supplies should be worn during operation to avoid direct contact with the skin and eyes.
6.2 Storage conditions
Diethers should be stored in a cool, dry and ventilated place to avoid direct sunlight and high temperature environments.
6.3 Adding quantity control
The amount of bis ether should be controlled according to the specific use environment and requirements to avoid excessive addition, resulting in degradation of coating performance.
7. Conclusion
Bis-(2-dimethylaminoethyl)ether, as a highly effective anti-mold agent, exhibits excellent long-term protection in anti-mold coatings. By inhibiting mold growth, inhibiting mold metabolism, and inhibiting mold spore formation, bis ether can effectively extend the service life of anti-mold coatings and reduce maintenance costs. At the same time, bis ether has good environmental friendliness and can meet modern environmental protection requirements. In actual application, the amount of bis ether should be reasonably controlled according to the specific use environment and requirements to ensure the performance and use effect of anti-mold coatings.
