Since the outbreak of the new corona epidemic, many places in the country have repeatedly reported that the new corona virus nucleic acid test positive for the outer packaging of cold chain items, and the new type of corona virus pneumonia caused by cold chain items have occurred from time to time. Liaoning Fortone Nano materials Co., Ltd. thinks about what the country wants and what the people need, according to the National Health Office Supervision Letter (2020) No. 1062 "Annex: Technical Requirements for Hygienic Safety Evaluation of Low Temperature Disinfectants" issued by the General Office of the National Health Commission. Under the precise guidance of the Provincial Health Commission and the Provincial Center for Disease Control and Prevention, a large number of scientific research personnel have been concentrated to cooperate with expert teams who have engaged in professional research for decades. Based on chain logistics disinfection equipment, normal temperature nano silver disinfectant, and nano silver masks, the Silver Guard low temperature disinfectant that can effectively inactivate and sterilize at -20°C has been developed. After being tested by CMA inspection institute, it is in full compliance with the national "Sanitation and Safety Evaluation Regulations for Disinfection Products", becoming the first domestic low-temperature disinfection that has completed formal filing in the country.

Silver Guard low-temperature disinfectant is widely used in the surface disinfection of various packaging materials, cabins and other objects under low temperature conditions involved in the cold chain and non-cold chain links. It can completely solve the virus spreading problem of imported products during production, processing, storage, transportation, circulation, transaction and other links. It has turned the cold chain into a "safe chain", providing a Chinese plan for fighting the epidemic and filling the domestic gap.
