Preservative manufacturers How do preservatives solve antibacterial problems? The antiseptic active ingredient is ion-exchanged active silver, which is characterized by excellent antibacterial properties, broad spectrum, safety and non-toxic characteristics. Compared with antibacterial agents, it has a high temperature resistance and long-lasting effect. It is an important new generation of environmentally friendly antibacterial product additives.
The drug has good antibacterial properties, wide spectrum sterilization, safety and non-toxic. Acute oral toxicity test,LD50>5000mg/kg, belongs to the actual non-toxic grade. The antiseptic agent has a small antibacterial concentration (MIC value). The antiseptic has stable physical and chemical properties, high temperature resistance and long-lasting effect. Small particle size, does not change color, can be used for film, microfiber and other special occasions
The preservative is white powder, average particle size D50 < 1.0μm, solid density 0.5-0.6g/ml, moisture content 0.5%, PH value 7-8, burning loss ≤1.0%, temperature resistance > 1000℃, whiteness ≥95, lower antibacterial concentration MICmg/kg: E. coli 130, Staphylococcus aureus 120, Candida albicans 140, antiseptic agents are widely used in rubber and plastic, chemical fiber, ceramics, fabrics, coatings, adhesives.
In plastic applications, a masterbatch containing 20‰ anti-corrosion powder can be prepared in advance, and then the anti-corrosion masterbatch is added to the base material in proportion. Ensure that the final product contains antibacterial powder in 3.0-5.0‰, the addition amount of antibacterial powder on rubber products is 3.0-5.0, and ‰ can be directly added to the product during processing. In the chemical fiber, the masterbatch containing 20% of the antibacterial powder can be made in advance, and then the antibacterial masterbatch is added to the chemical fiber material in proportion to ensure that the content of the antibacterial powder of the product is about 5.0‰. The amount of antibacterial powder added in the antibacterial glaze of ceramic products is 3‰. In coatings and adhesives, the amount of antibacterial powder added is about 5.0‰.
