In the medical field, catheters, as key devices connecting the inside and outside of the human body or different parts within the body, are widely used in scenarios such as drainage, drug administration, interventional diagnosis and treatment, and monitoring. However, the direct contact of the catheter with body fluids and blood makes it a breeding ground for microorganisms, significantly increasing the risk of nosocomial infection. According to statistics, the global medical expenses caused by catheter-related infections exceed several billion US dollars each year, among which urinary tract infections associated with catheters and central venous catheter-related bloodstream infections account for a relatively high proportion. Therefore, adding antibacterial agents in catheter production has become a core strategy for enhancing medical safety. I. The Core Role of Antibacterial Agents in Catheter Production

Disposable tableware: After adding antibacterial and antifungal agents to foaming materials such as polystyrene foam board (EPS), it can inhibit the growth of microorganisms caused by food residues, extend the shelf life of tableware, and at the same time reduce the risk of material degradation caused by mold erosion. Packaging field

If the plastic powder needs to undergo antibacterial treatment, Tianshi Landun Silver Ion Antibacterial Agent can be added. The characteristics, antibacterial principle and addition suggestions of the powder coating antibacterial agent are as follows:

In the production of wallpaper, adding anti-mold and antibacterial agents can start from aspects such as choosing the appropriate type of antibacterial agent, optimizing the addition process, and combining with other anti-mold measures. The following are specific solutions:

Antibacterial agents for PET are mainly classified into inorganic antibacterial agents, organic antibacterial agents and compound antibacterial agents. They are widely used in fields such as food packaging, pharmaceutical packaging, textiles, building materials and medical devices.

Antibacterial agents for inorganic coatings are a type of additive that achieves antibacterial functions through inorganic components. They have the advantages of high safety, good heat resistance, and long-lasting antibacterial properties, and are widely used in fields such as construction, medical care, and home appliances. The following is a detailed introduction from aspects such as classification, antibacterial mechanism, and application scenarios:

In UV floor paint,the selection of antibacterial agents is of vital importance. The following are some recommended types of antibacterial agents and their characteristics:

When the cold air is blown back into the air conditioner, causing condensation, the areas with water are prone to mold. While the air conditioner's windscreen blocks the direct blowing of cold air, it may also cause the temperature at the air outlet to be too low and condensate water to drip due to the obstruction, making the room damp and accelerating the rate of mold growth.

Low toxicity: Zinc is an essential trace element for the human body (the recommended daily intake is about 8-11 mg). A small amount of migration is usually harmless, and its safety is higher than that of silver ions (which may accumulate) or organic antibacterial agents (such as triclosan). Food-grade certification: Complies with the standards of food contact materials in various countries (such as FDA, EU 10/2011, and Chinese GB 4806), and is suitable for long-term use.

Surface coating: Suitable for post-processing antibacterial treatment. The adoption of plasma pretreatment technology to enhance the surface energy of TPE films can improve the adhesion of silver nanoparticle coatings.
