Dust and microbial metabolites in building envelope materials provide nutrients for mold. As a porous material, diatom mud is more likely to absorb moisture, creating a breeding ground for mold. Diatom mud powder anti-mold agent is an additive specially designed for diatom mud coatings.

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.

Silver ions/copper ions: Achieve broad-spectrum antibacterial effects by destroying the cell structure of microorganisms and are suitable for plastic handles. When adding, the dosage should be controlled (such as 0.3%-0.8%) to avoid the risk of yellowing or toxicity caused by the precipitation of metal ions. Nano zinc antibacterial agent: Utilizing nano zinc oxide technology, it is safe, environmentally friendly and has a high antibacterial efficiency. It is suitable for food contact grade materials (such as toothbrush handles) and can inhibit Escherichia coli, Staphylococcus aureus, etc.

Driven by the dual impetus of enhanced public health awareness and the iteration of antibacterial technologies, the integration of oil-based coatings and silver-ion antibacterial agents is becoming an innovative direction in fields such as construction, healthcare, and food processing.

Types and mechanisms of action of antibacterial agents Silver ion antibacterial agent

This long-lasting antibacterial property is suitable for scenarios that require long-term protection, such as file paper and library paper.

In daily life washing products, laundry detergent is widely welcomed because of its convenient use and good cleaning effect.

In the interior decoration of homes and public places, latex paint is popular because of its good covering power, easy construction and fast drying speed. However, a common problem is the wall due to moisture or poor ventilation caused by mildew

The polyester slices containing antibacterial components are combined with ordinary polyester slices by a twin-screw extruder to form fibers with special structures (such as skin core type and parallel type). This method can reduce the amount of antibacterial agent and maintain excellent antibacterial effect at the same time, but there are problems of difficulty and high cost in the processing of spinneret.
