Dibromonitrilopropionamide (alias dibromocyanoacetamide, DBNPA for short) is a new and efficient bactericidal algaecide and water treatment agent. The material has the advantages of high-efficiency broad spectrum, easy degradation, no residual residue, no pollution to the environment, and at the same time,

Antibacterial masterbatches in polyester films have become the core material for achieving antibacterial functions by enhancing the dispersibility of antibacterial agents, ensuring antibacterial stability, guaranteeing the accuracy of dosage, and simplifying the production process.

The eco-friendly anti-mold agent for interior wall putty powder is an additive specially designed for interior wall putty powder, aiming to prevent mold growth, protect the wall from moisture and mold damage, and at the same time meet environmental protection requirements. The following is a detailed description of its core characteristics, components, mechanism of action and usage methods:

In modern life, whether it is food, cosmetics, medicines or even some industrial products, during their production, storage and transportation, they all face an issue that cannot be ignored - microbial contamination and infection. Microorganisms are a broad category of terms, mainly including bacteria, fungi, and yeasts, etc. Their presence may lead to product spoilage and deterioration

High-temperature resistance and chemical stability: The anti-corrosion coating can maintain stable performance in high-temperature environments and has good mechanical and chemical stability, making it suitable for complex environments. Environmentally friendly and non-toxic: The product is non-toxic, odorless, and non-corrosive, and is classified as a non-hazardous material. It meets environmental protection requirements and is harmless to human health and the environment.

We often encounter situations where items come apart. Sometimes, something we bought not long ago is accidentally damaged. It would be a pity to replace it with a new one. At such times, glue comes in handy. As is known to all, glue is an intermediate that connects two materials. But how can it be used if it deteriorates? In the production of glue, to extend the service life of the product, glue anti-mold agents are definitely added The conditions for the survival of microorganisms when glue deteriorates

Waterborne polyurethane coating antibacterial and antifungal agents are chemical additives added to waterborne polyurethane coatings to inhibit or kill bacteria, mold and other microorganisms, prevent the coating from moldy and deteriorating, and protect the coating and substrate from microbial erosion. This type of additive achieves anti-mold and antibacterial effects by disrupting the cellular structure of microorganisms, interfering with metabolic processes, or forming protective films. Its core functions, common types, and practical applications are as follows

Adding antibacterial agents in additive manufacturing (3D printing) can significantly enhance the functionality and safety of printed products, especially in fields with strict hygiene requirements such as medical care, food packaging, and public health, where it holds significant application value. The following is a detailed analysis of the core role of antibacterial agents in additive manufacturing and their specific application scenarios: I. The Core Role of Antibacterial Agents Inhibit the growth and reproduction of microorganisms Antibacterial agents directly kill or inhibit the activity of bacteria, fungi and other microorganisms by destroying the cell walls of bacteria, interfering with metabolic processes or inhibiting DNA replication. For example: Nano-silver: It releases silver ions to penetrate the cell membrane and combine with sulfur groups in proteins, leading to the death of bacteria. Nano zinc oxide: It generates hydrogen peroxide through photocatalysis, oxidizes the structure of bacterial cells, and simultaneously releases zinc ions to interfere with enzyme activity. Quaternary ammonium salts: Adsorbed on the surface of bacteria, they damage the integrity of cell membranes and cause leakage of contents. Prevent cross-infection In the medical field, the surfaces of 3D-printed implants, surgical instruments or prosthetic limbs are prone to becoming breeding grounds for bacteria. Adding antibacterial agents can form a sustained antibacterial barrier and reduce the risk of postoperative infection. For example: Orthopedic implants: The surface of 3D-printed titanium alloy bone screws is loaded with an antibacterial coating, which can inhibit the adhesion of drug-resistant bacteria such as Staphylococcus aureus. Respiratory tract stents: Stents printed with antibacterial PLA material can reduce complications of pulmonary infection. Extend the service life of the product

I. The Core Role of antibacterial and antifungal agents in shoe material fiberboard Shoe material fiberboard (such as midsoles, linings, insoles, etc.) contains organic matter (proteins, animal fats) and is in a humid environment, which is very likely to breed mold and bacteria, causing the products to become moldy, have an unpleasant smell, and even rot. Antibacterial and antifungal agents achieve the following functions by disrupting the cellular structure or metabolic processes of microorganisms:

I. Mechanism of Action: Multi-dimensional inhibition of microbial growth Cell membrane destruction: Metal ions (such as silver and zinc) and some organic molecules penetrate the cell membrane of microorganisms, causing cytoplasmic leakage and leading to cell death. Metabolic inhibition: Organic compounds (such as quaternary ammonium salts and pyridines) disrupt the energy production systems of microorganisms by inhibiting enzyme activity, thereby blocking their growth and reproduction.
