Recently, the term antibacterial often appears in various media and people’s speech. It is a new vocabulary created by people’s need for a comfortable and clean living environment in recent years, and it is not a professional term. We explain it as follows:
1. Resistance and killing of bacteria living in the living environment;
2. It is not a temporary effect, but an effect that lasts from a few weeks to a few years;
3. Maintain a microbiologically clean living environment for a long time.
1. What types of antibacterial agents are there?
There are two series of antibacterial agents, one is organic series and the other is inorganic series. There are many types of organic products, generally products similar to pesticides, some of which can even induce cancer. Most of them are unstable substances that easily evaporate and decompose when the temperature reaches about 300 degrees. On the contrary, the inorganic series of antibacterial agents are composed of inorganic substances. Even the temperature at which the resin is molded cannot affect its functionality. Inorganic antibacterial ingredients such as silver (Ag), copper (Cu) and lead (Zn) also have excellent safety properties.
2. What is the difference between antibacterial agents and antifungal agents?
Because bacteria are different from mold, antibacterial agents are different from antifungal agents. Antibacterial agents have an excellent effect on killing bacteria. Antifungal agents have no effect on bacteria at all. In conclusion, the mainstream of antibacterial agents is inorganic series. There is nothing that works for both sides yet.
3. Are inorganic series antibacterial agents more expensive than organic series?
Since inorganic series antibacterial agents use silver ions, the price is a bit high. However, since the inorganic series of antibacterial agents last much longer than the organic series, they actually reduce costs in terms of long-term use.
4. Regarding safety, why are inorganic series of antibacterial agents relatively high?
The antibacterial effect of inorganic series antibacterial agents is due to the antibacterial effect of silver (Ag). Silver has been used in daily life a long time ago. For example, tableware, dental repair materials, decorations, etc.
5. What is the antibacterial mechanism of silver?
There is no conclusive conclusion on the antibacterial properties of silver. But everyone thinks as follows:
1. Transform oxygen in the air and dissolved oxygen in water into active oxygen. It damages the surface structure of the bacterial body.
2. When trace amounts of silver particles come into contact with bacteria, the bacteria initiate enzyme disorders and hinder bacterial development.
6. Are there many types of inorganic antibacterial agents?
The main difference between different types of inorganic antibacterial agents is the different carriers of antibacterial ingredients. Generally, zeolite is used as a carrier, as well as phosphoric acid, calcium, silica gel and glass.
7. What are the characteristics?
Here is a brief explanation:
1. Mix silver oxide into the soluble glass structure. Silver oxide is stable in form and evenly distributed.
2. Since silver ions easily change color when exposed to light, in order to prevent discoloration, special ingredients are mixed with glass to keep the color unchanged. Therefore, when microparticles of transparent glass are added to transparent resin, the transparency of the resin will not be affected.
3. It has strong antibacterial ability. Adding a small amount will have a significant antibacterial effect. Extended reading: https://www.yingjietex.com/product/Polyester-Oxford-cloth -bag-Fabric.html
