The anti-virus rate of H3N2 should be greater than

The anti-virus coating standard was issued, and the anti-virus rate of H3N2 should be greater than or equal to 99.9%

the anti-virus coating standard is released, and the anti-virus rate of H3N2 should be greater than or equal to 99.9%

December 1, 2020, two group standards, antibacterial and antiviral coatings and testing methods for antiviral properties of coatings (paint films), were issued in Beijing, breaking the lack of international standards for antiviral coatings, which will provide effective specifications and clear basis for the antiviral coating Market and escort the healthy life of the people

the demand for anti-virus coatings highlights

research shows that 80% of common infections (such as colds, influenza, diarrhea, etc.) are actually transmitted by contacting the surface of contaminated objects. With the increasing improvement of consumers' living standards, the demand for anti-virus products is increasingly urgent. As the outermost layer of any consumer end product, coatings have the closest daily contact with consumers. Coatings and coating products with anti-virus function are of great significance to improve consumers' living standards and reduce the risk of infection

in the coating industry, effectively promoting the development of antiviral and antibacterial coating technology and products must be the focus of attention in the industry at present, and is expected to become a new growth point for a long time in the future

the market of anti-virus and anti-bacterial coatings urgently needs to be standardized.

the group standard of anti bacterial and anti-virus coatings defines that the anti-bacterial and anti-virus properties of coatings should meet the requirements of three aspects, including anti-bacterial properties, anti mold properties and anti-virus properties. Among the class I antiviral performance, the antiviral rate of H3N2 should be greater than or equal to 99.9%, and the antiviral rate of EV71 should be greater than or equal to 95.0%. The group standard "test method for antiviral performance of coatings (paint films)" stipulates the terms and definitions, test principles, reagents and materials of antiviral performance test of coatings (paint films), which is applicable to the determination of antiviral performance of coatings (paint films)

sun Lianying, President of China Paint Industry Association, said: "With the rapid development of technology, coatings have both protective and decorative functions, but also become more and more functional. Considerable progress has been made in self-cleaning, self-healing, reflective heat insulation, stealth, bioactive intelligence, etc. and the research and development of coating technology and products with antibacterial and antiviral functions is another embodiment and breakthrough of the functionality of coatings. It is not only of great significance to improve the living standards of consumers and reduce the risk of infection It is of great significance and will certainly become the focus of common concern of the industry and consumers in the future. How to effectively regulate the anti-virus and anti-bacterial coating market, how to scientifically determine the anti-virus performance of coatings, how to introduce anti-virus and anti-virus coatings into the correct development path, and how to protect people's health and life safety are not only the responsibility of coating people, but also become a new proposition in front of coating people. The introduction of anti-virus coating and its testing method standards is particularly urgent. "

it is understood that at present, there are clear national standards for antibacterial coatings as a reference, but there is no mature test method for antiviral coatings in China. The anti-virus mechanism of coatings has not been clearly described by various coating enterprises. Some enterprises only test the killing ability of a virus and claim to be products with "anti-virus" function. As early as August 2019, China Paint Industry Association began to prepare the pre research of anti-virus paint related standards. In particular, the outbreak of COVID-19 this year has promoted the development progress of the standard. In April, 2020, the two group standards were officially approved by China Paint Industry Association. Guangdong Institute of Microbiology, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, China General Academy of building materials science, as well as more than 100 well-known institutions and enterprises such as sankeshu, Nippon, foster, PPG, garberry and Dow have actively participated in the preparation of the two standards. After pre research, project approval, drafting, consultation, review, approval, publication and other links, after many discussions by the working group, A large number of experiments have been carried out. With the enhancement of safety awareness and the improvement of environmental protection standards, the standard was finally released to the whole society on December 1, 2020

Xie Xiaobao, a researcher at Guangdong Institute of Microbiology, said that the ball screw has almost no self-locking property, while the trapezoidal screw has a certain self-locking property. There are many kinds of pathogenic viruses, so it is necessary to select a representative strain as the test virus. Therefore, according to the principle of anti-virus, developing new alternative experimental viruses is the further work that the majority of research and testing institutions need to carry out. The development of antiviral functional coatings (paint film) industry and the research of test standards should promote each other. On the one hand, the development of the industry needs the improvement and formulation of testing standards; On the other hand, continuous research and development of methods and evaluation standards for recycling waste plastics into environmentally friendly 3D printing materials in China can not only standardize the market and promote the benign competition of the industry according to the positioning, zero position and hammer lifting buttons, but also help to improve the quality of products, increase the added value of products, integrate with the world, break technical barriers and achieve higher economic benefits
