Antibacterial master grains, antibacterial plastics
Antibacterial plastics are a type of plastics that can inhibit or kill the undefined, mold, alkyd, algae and even viruses that contaminate the plastics in the environment and keep themselves clean by inhibiting the reproduction of microorganisms.
At present, antibacterial plastics are mainly obtained by adding a small amount of antibacterial agents to ordinary plastics.
In the use of antibacterial plastics, it is necessary to meet the necessary requirements of physical, chemical and mechanical properties of plastics when they are used as basic materials. Meanwhile, it is necessary to consider the requirements of the special function of antibacterial and the additional factors arising therefrom.
Therefore, antibacterial plastics should have a good mechanical strength appearance, chemical stability, good machinability.
In terms of antibacterial property, it is required that antibacterial plastics can adapt to the use environment and should have undefined, broad spectrum and long-term antibacterial property.
As antibacterial plastics contain a small amount of antibacterial agents, it is required that the antimicrobial agents used should meet the specified hygienic safety and the requirements of undefined antibacterial plastics to be undefined, odorless and environmentally sound.
The antibacterial additives used for antibacterial plastics are generally divided into organic, inorganic and natural antimicrobials.
From the middle of the century when more organic antimicrobials were used to finish the fabric, to the rapid development and application of inorganic antimicrobials after the 1980s, the development of antimicrobial plastics has entered a new era of inorganic organic-composite antimicrobial.
The study of inorganic and organic composite methods and their application is of great significance to give play to the antibacterial characteristics of these two kinds of materials.
In addition, more and more attention has been paid to the synthesis of active antibacterial compounds directly on the polymer chain.
The study of these new subjects will further improve the antibacterial properties of materials and have positive effects on environmental protection.
After being applied in household appliances and daily necessities, antibacterial plastics will be more and more applied in building materials and interior decoration materials.
The interior of the undefined sedan will also be increasingly made of antibacterial materials, such as nissan's steering wheel, interior flannelette, seat and handle, which have been made of antibacterial plastics and materials.
In order to make the performance of antibacterial plastics more excellent, the method of antibacterial mother granule is mainly adopted in the processing process, and the nanoringwei inorganic antibacterial mother granule is prepared by undefined environment-friendly nano-zinc oxide powder through unique grinding and dispersing and wet granule making process.
Due to the extremely fine nano particles, the crystal structure and electronic structure of the surface are changed, which makes them possess the unique characteristics of nano powder. The products with anti-bacterial master grains have the functions of strong sterilization, deodorization, mildew prevention and purification.
As nano-zinc oxide has the properties of light, electricity, magnetic and thermal sensitivity, the material is highly active and has the functions of anti-infrared ultraviolet and anti-aging.
