Application of antibacterial agents and antibacter

  • Detail

The application of antibacterial agents and antibacterial materials in packaging

with the development of science and technology and the improvement of people's living standards, people's health awareness is constantly enhanced, and higher attention is paid to the health of daily necessities, especially food, and the cleaning of the environment. However, in people's daily living environment, pathogenic microorganisms such as bacteria are everywhere, threatening human health. The development and application of antibacterial materials can effectively reduce or avoid the cross infection of bacteria and the spread of diseases

development status of antibacterial materials

antibacterial materials refer to a new type of functional materials that have the function of killing or inhibiting microorganisms. In nature, there are many substances that have good functions of sterilization or inhibition of microorganisms, such as some organic compounds with specific groups, some inorganic metal materials and their compounds, some minerals and natural substances. However, at present, antibacterial materials refer to a new type of functional materials that have the ability to inhibit or kill surface bacteria by adding certain antibacterial substances (called antibacterial agents) in the national economy, such as antibacterial plastics, antibacterial fibers and fabrics, antibacterial ceramics, antibacterial metal materials, etc

the large-scale application of modern antibacterial materials began during the Second World War. The German army once wore military uniforms processed with antibacterial finishing, which reduced the bacterial infection of the wounded and the reduction of casualties. After the 1960s, antibacterial sanitary fabrics began to be popularized in civilian products. Antibacterial agents used for antibacterial finishing are mainly added with strong antibacterial chemicals such as organotin and chlorophenols. In the 1980s, the successful development of antibacterial fibers ensured the long-term durability of antibacterial textiles. With the rapid development of petrochemical industry, plastic products have become an indispensable necessity in daily life. It is reported that the world's plastic output reached 135 million tons in 1997, with an annual increase of 5%. Since the 1980s, the development of antibacterial plastics and its application in household appliances? The wide application of antibacterial materials in kitchen and bathroom facilities, communications, daily necessities, automobiles, building materials, toys and other industries has brought antibacterial materials into a rapid development stage. Among them, European and American countries are mainly used for daily necessities? Toys and other end products. Japan is the most developed country in the development and application of antibacterial materials, which are mainly used in household products at present? Household Electric Appliances? Toys and other fields. Household products are mainly concentrated in bath and sanitary products, indoor products, etc. Household appliances are currently one of the industries with the widest application of antibacterial materials. The first phase focuses on the introduction of mobile phone sheath materials and the largest use. The production of antibacterial, antibacterial washing machines, antibacterial electric cookers, antibacterial electric fans, antibacterial refrigerators, antibacterial air conditioners, etc. occupies a considerable share in the domestic market in Japan

in China, the development and production of antibacterial materials were relatively late. Until the mid-1990s, antibacterial materials in China were almost blank except for a few fields such as coating corrosion prevention

over the past few years, China has been following the development of international inorganic antibacterial agents. China has achieved fruitful results in this field, and an antibacterial material related industry has begun to take shape. In the middle and late 1990s, antibacterial agents? Antibacterial plastics have entered a period of rapid development in China. It is estimated that in 1999, the output of antibacterial agents in China reached 150 tons, the sales volume was 12million yuan, and the output value of antibacterial products was 10billion yuan. It is estimated that the output of antibacterial agents will reach 500 tons in 2005, and the output value of antibacterial products will be 40 billion yuan. A large number of enterprises and colleges and universities? In close cooperation with scientific research institutions, rapid development has been made in the industrialization and application development of inorganic antibacterial agents, organic antibacterial agents, photocatalytic antibacterial agents and antibacterial materials, in which the impact energy of projectiles can also dissipate rapidly along the direction of fibers. The cooperative project "development and application of antibacterial household appliances and antibacterial plastics" between the Chinese Academy of Sciences and Haier Group won the second prize of the 2000 National Science and Technology Progress Award for hydrolysis and chemical change, marking that the development and application technology of antibacterial materials in China has entered the international advanced ranks. Based on the successful development of ZnO crystalline composite antibacterial agent, the school of materials science and engineering of southwestjiaotonguniversity applied it to plastic packaging materials, and developed antibacterial packaging bags with an antibacterial rate of more than 99%. Due to the unique colorless property of ZnO crystalline composite antibacterial agent, adding it to the substrate will not change the color of the substrate, so it can be made into transparent polycarbonate? Polyethylene antibacterial material. In addition, due to the multifunctional characteristics of ZnO crystal itself, the plastic packaging materials added with ZnO crystal composite antibacterial agent also have the characteristics of high strength and good freshness. In addition to plastic packaging, it can also be used for painting the surface of paper packaging and metal packaging. This kind of antibacterial packaging material has attracted extensive attention of users
