What is inorganic antimicrobial agent, basically be to point to the metal such as silver copper zinc or its ion, use physical adsorption ion exchange method, attached at porous material, use the antimicrobial ability of metal ion, through slow release action achieves the goal of long effect inhibitory bacteria. Among many metal ions, mercury, silver, cadmium, copper and zinc all have strong antibacterial ability, but when used, silver, zinc and copper ions are safe and non-toxic, and the antibacterial ability of silver ions is far stronger than that of other metal ions such as zinc and copper. Therefore, inorganic silver antibacterial agents occupy the dominant position of inorganic antibacterial agents. According to the different carriers, different types of silver antibacterial agents have been developed, such as: silver zeolite, activated carbon, copper phosphate, calcium phosphate, silica gel, zirconium phosphate, hydroxyapatite silver, etc. Shanghai Ecolin Technology Co., Ltd. as a professional Shanghai inorganic antibacterial agent manufacturers, professional disclosure of inorganic antibacterial agents small knowledge.

Inorganic antibacterial agent main varieties:

Silver zeolite, silver activated carbon, silver silica gel, silver glass beads, silver hydroxyl phosphoash based antibacterial agent, titanium phosphate, silver/zinc compound.

Advantages of inorganic antibacterial agents:

Good heat resistance (>600℃), broad antibacterial spectrum, long effective antibacterial period, low toxicity, no drug resistance, high safety.

Silver ion antibacterial agents have the advantages of high antibacterial activity, good safety (less toxicity, no irritation, no carcinogenicity, no deformity, etc.), good heat resistance, etc. Among them, the MIC(low inhibitory concentration) of argoflospar against Gram-negative and Gram-positive bacteria was 62.5μg/kg-250μg/kg, the MIC for yeast was 250μg/kg-500 μg/kg, and the MIC for fungi was 500μg/kg-1000μg/kg.

Disadvantages of inorganic antibacterial agents:

Silver antimicrobial agent is easy to change color, manufacturing difficulties, in the use of materials in the process is complex.

1, due to the role of inorganic carrier, silver antibacterial agents will seriously affect the transmittance of products, especially thin film plastic products;

2, this kind of material free out of silver ions in the sun or heated to a certain temperature is easy to be reduced to elemental silver and gray or brown, affect the color of products;

3, the anti-fungal and mold effect is poor.

4. Due to the scarcity of silver raw materials, the cost of silver antibacterial agents has been high;
