Storage method
1. It should be stored in a cool, ventilated and dry warehouse, but not in a wooden warehouse.
2. Do not store and mix with flammables, acids and reducing agents. Pay attention to moisture. Keep away from heat and sources of ignition.
3. Protect from rain and sun during transportation. Handle with care when loading and unloading to prevent violent collisions. In case of fire, water, sand, and various fire extinguishers can be used to extinguish the fire.
Main purpose
1. Used for bleaching pulp, fiber, flour, starch, oil, etc., drinking water purification and sewage treatment, leather depilation and preparation of chlorine dioxide aqueous solution, etc. For high-efficiency bleach and oxidizer. It is mainly used as pulp, paper and various fibers, such as cotton, hemp and reed. Bleaching of viscose fibers, etc., as well as bleaching of sugar, flour, starch, grease and wax. It is also used for leather depilation, surface treatment of some metals, drinking water purification and sewage treatment, etc. It can be used as a discharge agent for indanthrene dyeing. oxidizing agent. fungicide. purified water. Fabric bleach.
2. Used as bleaching agent in food industry. It is mainly used for candied products. The aqueous solution of sodium chlorite has a stable bleaching ability under acidic conditions, and can be bleached after adjusting the pH value to 3-5 by adding citric acid. Corrosion-resistant containers are required for bleaching, and metal containers are not allowed. Japanese regulations limit it to cherries, butterbur, grapes and peaches. FDA (§ 186.1750, 2000) stipulates that it is limited to paper in contact with food, and the limit is 125-250mg/kg.
3. Efficient bleach and oxidizer. It is mainly used for bleaching pulp, paper and various fibers, such as cotton, hemp, reed, viscose fiber, etc. It can also bleach white sugar, flour, starch, grease and wax. It is also used for leather depilation, surface treatment of some metals, drinking water purification and sewage treatment, etc. It can be used as a discharge agent for indanthrene dyeing.
4. Used for drinking water purification, no residual chlorine odor treatment of sewage, has the functions of sterilization, phenol removal and deodorization. This product is also a high-efficiency bleaching agent, which is used to bleach fabrics, fibers, and pulp, and has the characteristics of little damage to fibers.

Toxicological data
Rat oral LD50: 166mg/kg. Groundhogs can die in the air containing 45mg/kg chlorine dioxide for several hours. Irritant to mucous membranes of respiratory organs and eyes.
Stable in nature
1. Easily soluble in water (34% at 5°C; 46% at 30°C). The anhydrous substance will not decompose when heated to 350°C, and the general product will decompose when heated to 180-200°C due to the moisture content. Alkaline aqueous solution is stable to light, while acidic aqueous solution will decompose explosively and release chlorine dioxide under the influence of light. Strong oxidizing agent, its oxidizing ability is 4-5 times that of bleaching powder and 2-3 times that of bleaching powder. Contact with combustibles and mixing with organic matter can cause an explosion.
2. The dust of this product can irritate the mucous membranes of respiratory organs, eyes and skin. Inhaling the dust of this product will cause poisoning due to accumulation in the body, and symptoms such as nausea, vomiting, diarrhea, dyspnea, and kidney damage will occur.
