Antimicrobial fungicides are chemicals that can keep the growth or reproduction of certain microorganisms (bacteria, fungi, yeasts, algae and viruses) below the necessary level for a certain period of time.
What are the categories of antimicrobials? Jingan Xiaobian to tell you about the classification of antimicrobials, so that you know more about antimicrobials, use more assured.
Antimicrobial agents are divided into organic, inorganic and natural three kinds.
First, inorganic antibacterial agent
It mainly refers to the metal such as silver copper zinc or its ions, using physical adsorption ion exchange method, attached to porous materials, the antibacterial ability of using metal ions, through slow release action to achieve the purpose of long-term effect and bacteriostasis.
Among many metal ions, mercury, silver, cadmium, copper and zinc all have strong antibacterial ability, but they are safe and non-toxic to silver, zinc and copper ions when used, and the antibacterial ability of silver ions is far stronger than that of other metal ions such as zinc and copper.
Inorganic antibacterial agents have the characteristics of good heat resistance, long effective antibacterial period, low toxicity, no drug resistance and high safety.
Inorganic antibacterial agent representative: silver ion antibacterial agent
Two, organic antimicrobial agents
Organic antibacterial agents mainly through the addition of plastic, through the migration to the plastic surface, play a continuous bactericidal effect. However, the compatibility of organic antimicrobial agents should be considered when they are applied to different kinds of plastics.
Organic antibacterial agents have the characteristics of fast sterilization, strong sterilization ability, convenient processing, good color stability and so on.
But the organic antibacterial agent heat resistance is poor (plastic processing temperature is easy to decompose failure, and decomposition products may cause secondary pollution), easy to precipitate in the solvent environment, easy to produce drug resistance, decomposition products toxic, safety has not been completely determined.
Three, natural antimicrobial agents
It is mainly extracted from natural plants, such as chitin, mustard, castor oil, horseradish, etc., which is easy to use, but has limited antibacterial effect, poor heat resistance, low fungicide rate, and can not be used in a broad spectrum and long-term effect and the quantity is very small.
Whether organic antibacterial agent, inorganic antibacterial agent, or natural antibacterial agent, its advantages and disadvantages exist at the same time, the factory with according to customer requirements and their own process needs combined to choose the most appropriate product antibacterial solutions
