What is inorganic antibacterial agent, inorganic antibacterial agent is the main use of silver, copper, zinc and other metal itself has antibacterial ability, by physical adsorption or ion exchange method, such as silver, copper, zinc and other metal ions (or its) fixed on the surface of the porous material such as zeolite, silica gel or the pore, and then added to the products obtained with antimicrobial properties of materials.

Classification of inorganic antimicrobial agents: inorganic antimicrobial agents can be divided into two categories according to the antimicrobial mechanism: one is the antimicrobial agents with metal ions or their compounds as the main antimicrobial components. According to the different types of carrier materials, the antimicrobial agent can be divided into zeolite antimicrobial agent, phosphate double salt antimicrobial agent, soluble glass antimicrobial agent, bentonite antimicrobial agent, etc. Zeolite is a kind of alkali metal or alkaline earth metal crystalline silicon aluminate, its structure determines the zeolite has a strong cation exchange capacity; At the same time, zeolite is a carrier of the strongest antibacterial. So metal/silicate antibacterial agents have been mature applications. For example, Sinanenzeomic's proprietary product, ZeomicXawlod, is silver or silver and zinc/A zeolite. Because calcium phosphate has a good affinity with organisms, the research of metal/phosphate antibacterial agents is also very active. Silver/activated carbon and silver/carbon fiber antimicrobials (metal/activated carbon) are commonly used in water purification treatment.

The second category is represented by titanium dioxide with photocatalytic activity of antimicrobial agents. The advantage of this kind of antimicrobial agent is heat-resistant than general inorganic antimicrobial agent is high, but it is necessary ultraviolet radiation and oxygen (or water) existence ability has bactericidal effect. The experiment proved that a layer of TiO2 on the glass and given three hours of light can kill E. coli, if given four hours of light can make the toxin content under 5%.

Advantages of inorganic antibacterial agents:

Compared with organic antimicrobial agents, inorganic antimicrobial agents have outstanding advantages, mainly in the following aspects:

(1) High safety.

(2) good slow release, so it has better durability.

(3) It has a broad spectrum of antibacterial properties. Different kinds of metal ions have different antibacterial and bactericidal effects on various kinds of bacteria. The test results showed that the anti-bacterial and anti-fungal effects of various ions were as follows : Ag>Co>Ni≥Al≥Zn≥Cu=Fe≥Mn≥Sn>Ba≥Mg≥Ca及Ni>Cu≥Co>Zn=Ag>Fe≥Al≥Sn：Mn≥Ba≥Mg≥Ca . Among the metal ions that have antibacterial effect on bacteria or mold , the following seven metal ions have strong bactericidal effect on Escherichia coli , the strength of which is :Ag>Cu>Fe=Sn>Al≥zn≥Co . In conclusion, compared with other metal ions, silver ions have stronger antibacterial and bactericidal effects. Copper is second. This is also an important reason why these two metal ions are used as the main active components in inorganic antimicrobial agents.

(4) It is not easy to develop drug resistance.

(5) good heat resistance.

(6) convenient processing.
