In the fields of industrial production and daily chemicals, in order to ensure that products remain stable within their shelf life and prevent microbial contamination, specific components are often added

The PU sponge mop, with its strong water absorption, no need for hand washing, and clean water extraction, has become a cleaning tool for modern households. The new generation of PU cotton mop heads uses a new material formula without starch, effectively solving the usage pain points of traditional glue cotton mops such as "drying and hardening" and "requiring soaking before use"

they are prone to bacterial and mold growth, resulting in odors, mold spots, and stickiness. Conventional antibacterial additives are not suitable for the PVC extrusion and calendering high-temperature process, and may cause production and finished product defects such as yellowing, precipitation, poor dispersion, and short antibacterial duration.

Household plastic parts cover all scenarios of food preparation, storage and storage. Different usage environments give rise to different hygiene risks. A single antibacterial solution is unable to meet all requirements:

The rubber and plastic products have been upgraded with antibacterial functions. The stability, safety and processing compatibility of the core raw materials directly determine the quality of the finished products. Many rubber and plastic processing factories and product enterprises, when producing antibacterial plastics, will look for reliable and well-coordinated plastic antibacterial masterbatch brands. Dalian Tianwei , which has been deeply engaged in the field of microbial control additives for many years

Lactic acid gypsum relies on its modified adhesive properties and molding stability and is widely used in gypsum components, decorative gypsum, self-leveling gypsum, and craft gypsum and other building materials. However, the material has a weakly acidic pore structure, high organic matter of lactic acid, and strong hygroscopicity, which makes it prone to the growth of mold such as Aspergillus niger, Penicillium, and yeast.

Water-based anti-corrosion coatings use water as the solvent, and have high organic content in emulsions and additives. After storage in cans and after application and film formation, they are prone to bacterial, yeast, mold, and sulfate-reducing bacteria growth. These coatings are a high-risk category for microbial contamination in the coating industry. There are four prominent challenges in production and use:

The plastic hollow fiber membrane, with its advantages such as high flux, good strength, resistance to acid and alkali, and ease of processing, is widely used in fields such as water purification filtration, wastewater treatment, reclaimed water reuse, and biomedical filtration. However, the porous structure of the membrane body easily adsorbs bacteria, molds
