"Antibacterial technology is one of the applications in the home appliance I. Li Guohou's appearance of various household appliances has brought great convenience to people's lives. At the same time, due to the existence of bacteria, some modern diseases, such as "refrigerator synthesis" "", "air conditioning disease" and so on.
The scientific and technological community is committed to research and development of various antibacterial and antibacterial materials, which are added to household appliances. Explore ways to create a good home appliance sanitation environment using chemical disinfection, physical disinfection, and functional material disinfection. At present, the focus of domestic healthy home appliances is mainly in two aspects, one is antibacterial, and the other is deodorization. Antibacterial refers to bacteria or mold that inhibits or kills the surface pollution of home appliances, and prevents people and articles that may be caused when using home appliances. Or cross-contamination of food, such as antibacterial refrigerators, antibacterial washing machines, antibacterial phones, etc. The purpose of deodorization is to remove pollutants in the air, such as harmful organic matter. The deodorization method currently used is usually a combination of a technique of adsorbing harmful organic matter gas and decomposing an adsorbate, such as a health air conditioner using a catalyst filter, an air freshener using an ozone generator, and the like, and some products are simultaneously Use two or more techniques. The following discussion focuses on the development of antimicrobial technology and its application in household appliances.
Antibacterial technology originated in the United States in the early 1980s, and has also received widespread attention in Japan, mainly in the research of antibacterial agents and antibacterial plastics and their preparation methods. Antibacterial agents are divided into five major series: natural, organic and inorganic. There are not many varieties of natural antibacterial agents. The main product is chitosan, which has many functions such as moisturizing and antibacterial. It has not yet been mass marketed. Organic antibacterial agents mainly include organic acids, esters, alcohols and phenols. Quaternary ammonium salts, biguanides, isothiazoles, organic metals, heterocyclics, and the like. The organic system is the earliest commercial anti-interpreter organic antibacterial agent mainly used for processing low temperature PPVC, PE, etc., because of their poor heat-emitting properties, easy hydrolysis, short service life, etc., the development and use of organic antibacterial agents, Comprehensive consideration of antibacterial ability and material composite compatibility, long-lasting efficacy, chemical temperature, thermal stability and light stability and other factors; at present, the focus of research on antibacterial agents at home and abroad is inorganic antibacterial agents.
The inorganic antibacterial agent uses metal ions such as silver, copper and zinc as antibacterial components, and is supplemented with phosphate, zeolite, glass, hydroxyapatite and the like. Among them, the silver-loaded antibacterial agent has the strongest antibacterial ability. Commercially available inorganic antibacterial agents are mostly silver-based antibacterial agents such as silver-activated carbon, silver-zeolite, silver-cobalt phosphate, silver-silica gel, silver-calcium phosphate, silver-soluble glass, silver-clay minerals and the like. Inorganic antibacterial agents are characterized by high safety, good heat resistance, long-lasting antibacterial properties, and a wide range of applications, and can be used in almost all plastics. Inorganic is the main development direction of antibacterial agents.
Antibacterial plastic refers to the addition of an antibacterial agent to plastics to make the plastic products inherently antibacterial. Adding a small amount of plastic antibacterial agent can give the plastic long-term antibacterial ability. Antibacterial agents can be achieved by the ability of antibacterial agents to kill microorganisms and inhibit microbial growth, including bacteria, fungi, yeasts, algae, and viruses. Antibacterial plastics can make bacteria contaminated on plastics inactive for a certain period of time (24 hours), inhibiting their proliferation or killing. The antibacterial rate is usually a quantitative indicator. Tested under the conditions stipulated by the enterprise standard of Engineering Plastics National Engineering Research Center, the antibacterial rate is more than 90% qualified, and more than 99% is the first grade. The antibacterial effect of plastic is achieved by contact with bacteria. Antibacterial plastics have long antibacterial aging properties, and their antibacterial properties have an effective period of time equivalent to or longer than the design life of materials used.
It is generally required that the antibacterial property of antibacterial plastic products has high efficiency, broad spectrum, good persistence, no toxicity, no odor, and no impact on the environment. Generally, the higher chemical concentration in antibacterial plastics can be used for sterilization, while the lower chemical concentration can only inhibit bacteria, or it can stimulate the growth of bacteria. The amount of antibacterial agent added in antibacterial plastics is limited. To ensure that people's health and the smoothness of the surface of the material and the mechanical properties of the material are not affected. At present, the latest development trend of antibacterial materials in China has formed a momentum of comprehensive development and application in the fields of inorganic antibacterial agents, organic antibacterial agents and photocatalyst antibacterial agents, and a small number of products have been listed, and many of them have innovative technical routes. For example, nano inorganic particles are used to carry metal ions such as silver, nano-sized titanium dioxide photocatalysts, and the like. The research work of foreign household appliance plastic antibacterial agents mainly focuses on two types of organic antibacterial agents and inorganic antibacterial agents. 2. The application of antibacterial technology in household appliances utilizes the antibacterial properties of antibacterial materials, and the plastic parts of household appliances are treated with antibacterial treatment. Home appliances. In other words, the core technology of antibacterial appliances is the development of antibacterial plastics and their products (components). Antibacterial of home appliances is achieved by antibacterial components in home appliances. Such as antibacterial refrigerator: antibacterial of the door seal. To resist the invasion of external bacteria; the antibacterial of the handle (or handle, decorative strip) to kill the bacteria infected by the hand; the inner liner, the shelf for placing food (the bottle holder, the egg, the control panel, etc.) To inhibit the nuisance of food or food packaging: or contaminated bacteria.

Knob of coal stove. Due to the development and production of r home + sample, the product's anti-mite design is also different, for example, the manufacturer of the cattle. The hail produced only /1-: door handle, N seal Waiting for people to use antibacterial materials in frequent parts, iMM outside manufacturers are widely used in hail plastic parts, and developed countries in Fuxi 10 and Sakamoto are in household appliances, Shucun Village, potential overnight products, food packaging, U Changyi live goods, bath equipment, L negative toys, etc., began to use anti-mite and anti-mold materials, and gradually entered the practical stage, with anti-Nan plastic as the gray-resistant anti-interpretation The application of polymer materials to reduce the spread of disease and environmental pollution The meaning of the i should be pointed out by the concept of K, 系1, and anti-explanation. Depression refers to the suppression of fineness, and the number of details is not reduced. Killing the toes means killing the heart. 'Live bacteria; antibacterial contains antibacterial bacteria and kills the second / / surface of the Sichuan, which mainly emphasizes the inhibition, the beauty of the i - the antibacterial agent used in antibacterial plastics When it is used at low concentration, it has antibacterial activity. When it is still in concentration, it kills and explains ft: The disinfection of the foot refers to the elimination of the pathogen of the cockroach. The anti-explanation is based on the anti-description of the materials used, 1 system, The concept or use of dispelling is not enough. On the refrigerator if, Y, anti-explanatory refrigerators only have antibacterial effect on the bacteria in the 4 refrigerators that are resistant to the W material parts, ifri can not pick up the food or space stored in the refrigerator.
