The State Administration for Market Regulation and the National Standardization Administration recently released the national standard "sulfuryl fluoride fumigant", the standard number: GB/T 38211-2019, which will be officially implemented on July 1, 2020. Sulfuryl fluoride, also known as fluorine oxysulfide, is an excellent broad-spectrum fumigation pesticide that does not destroy the ozone layer and is widely used in many industries. 1. Construction industry. Sulfuryl fluoride has the characteristics of killing pests spreading in buildings, non-combustible, non-corrosive, etc., and can quickly penetrate into building materials. Since its listing in the United States in 1961, it has been used in the fumigation of buildings and building materials. Widely used, such as fumigating houses, other types of buildings (including museums, libraries, archives, churches, government buildings, etc.), historical sites, etc. So far, the construction industry is still its largest application field. Compared with methyl bromide, sulfuryl fluoride can penetrate building materials more quickly, can kill insects more effectively with a broad spectrum, and has fewer residues after fumigation. Especially in termite control, sulfuryl fluoride has basically replaced methyl bromide. 2. Food industry. Tests have shown that sulfuryl fluoride has a good killing effect on harmful organisms that endanger food. Through fumigation tests on dried fruits, cereals, flour and other major foods, the research on the residual amount has been completed. The results show that sulfur Acid fluoride does not affect the taste and quality of food. In September 2003, the Swiss government officially approved sulfuryl fluoride for commercial fumigation of food, becoming the first country in the world to use sulfuryl fluoride instead of methyl bromide in food fumigation. In January 2004, the U.S. Environmental Protection Agency also formally passed the registration of the use of sulfuryl fluoride in food fumigation, and in July 2005 established a standard for sulfuryl fluoride residues in food. In addition, Italy, the United Kingdom, Germany, Canada, France and other countries have also approved the use of sulfuryl fluoride for fumigation of food in warehouses. Therefore, Heptafluoropropane HFC-227EA will replace methyl bromide and other food fumigation will become a development trend.
