Use of sulfuryl fluoride fumigant

　　Sulfuryl fluoride fumigant has the characteristics of a broad insecticidal spectrum, strong diffusion, and permeability, low toxicity, less residue, wide temperature range, non-flammable, non-explosive, and non-corrosive. It can be widely used in warehouses, ships, carriages, containers, and other goods to kill insects and rodents. Buildings, reservoirs, and dams termite control. Greenhouse soil fumigation, etc. It is the most ideal fumigant at home and abroad currently used in logistics pest control, entry-exit health quarantine, and plant quarantine, as well as agriculture, forestry, commercial trade, traffic sanitation, water conservancy, construction, and other related industries. It is also an environmentally friendly fumigant that replaces methyl bromide (methyl bromide) and does not destroy the ozone layer. At present, the most commonly used fumigants in China are aluminum phosphide and methyl bromide. Aluminum phosphide has been widely used in grain and tobacco warehouses for a long time due to its advantages of convenient operation and low price. However, the phosphine gas released by aluminum phosphide during the fumigation process is highly toxic, flammable, and explosive, and there are many potential safety hazards. At the same time, its corrosiveness affects the material of the fumigated object. For example: in piano fumigation, while the wood-boring pests in the piano are effectively killed, the metal material inside the piano is also corroded to varying degrees, and the corrosion consequences will be latent and gradually revealed. Methyl bromide was originally a good fumigant, but due to its destruction of the atmospheric ozone layer, the international "Montreal Protocol" has listed it as a phase-out product. Because of this, the promotion and application of sulfuryl fluoride fumigant in various fields have gradually become a global inevitable trend.

　　The dangers of sulfuryl fluoride fumigant

　　It reacts with water or water vapor and emits toxic and corrosive gas. In case of high heat, the internal pressure of the container will increase, and there is a danger of cracking and explosion. It is a strong irritant to the eyes, skin, and mucous membranes. Can cause nausea, vomiting, abdominal pain, skin itching, and other symptoms. TLV-TWA: 20mg/m3≈4.79PPM. The acute toxicity of this product mainly damages the central nervous system and causes convulsions.
