Cope! These 4 kinds of goods belong to hazardous chemicals, but do not belong to dangerous goods
As we all know, hazardous chemicals are not equal to dangerous goods. What goods are judged to be hazardous chemicals but not dangerous goods according to the catalog of hazardous chemicals?
Boric acid
Boric acid CAS No.: 10043-35-3
Hazardous category: reproductive toxicity, category 1B
The chemical formula of boric acid is H3BO3, which is white crystalline powder. 1955, Liaoning Kaiyuan Chemical Factory took the boromagnesium ore containing more than 330% of B2O in Fengcheng Ertaizi as the raw material, and succeeded in obtaining boric acid by sulfuric acid decomposition method, and built the first boric acid production workshop in China.
Boric acid is widely used in industrial fields, such as for the glass industry, can improve the performance of glass products, can also be used to disinfect antiseptic, can also be used for flame retardant, etc., the use is very broad.
Diethanolamine
Diethanolamine CAS No.: 111-42-2
Hazard Category: Skin Corrosion/Irritation, Category 2; Serious Eye Damage/Eye Irritation, Category 1; Specific Target Organ Toxicity – Repeated Exposure, Category 2*; Hazardous to the Aquatic Environment – Acute Hazard, Category 2; Hazardous to the Aquatic Environment – Long Term Hazard, Category 3.
Diethanolamine (DEA), also known as 2,2′-dihydroxydiethylamine, is an organic compound and a substance on the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization. It is used as a gas purifier, corrosion inhibitor, coolant in automobile engines, drilling and cutting oils, and as a corrosion inhibitor in a variety of other lubricants. Follow Hazardous Dart to learn more about hazardous transportation.
Its storage conditions are strict, need to be stored in a cool, ventilated warehouse, away from fire, heat, and oxidizers, acids, etc. Separate storage, the operator needs to carry out strict protective measures before its operation.
Ethylene glycol monobutyl ether
Ethylene glycol monobutyl ether CAS No.: 111-76-2
Hazard Category: Acute Toxicity – Dermal, Category 3; Acute Toxicity – Inhalation, Category 2; Skin Corrosion/Irritation, Category 2; Severe Eye Damage/Eye Irritation, Category 2.
Ethylene Glycol Monobutyl Ether, an organic compound, is a colorless, transparent liquid mainly used as a high boiling point solvent for paints, especially nitro spray paints, quick drying paints, varnishes, enamels and strippers, and also used as an inactive diluent for adhesives, a metal detergent, a paint stripper, a fiber wetting agent, a pesticide dispersant, a drug extraction agent, and a plasticizer for resins. This substance used to be listed as item 6.1 on the TDG rules, UN2369, but the UN Secretariat explicitly deleted this entry on a document issued in 1994.
Magnesium nitrate hexahydrate
Magnesium Nitrate CAS No.: 10377-60-3
Hazard Category: Oxidizing Solid, Category 3; Serious Eye Damage/Eye Irritation, Category 2; Specific Target Organ Toxicity – Primary Exposure, Category 1; Specific Target Organ Toxicity – Repeated Exposure, Category 1.
Magnesium nitrate is a substance that can be used as a dehydrating agent for concentrated nitric acid, a catalyst, and a wheat ashing agent, etc. It is also a substance listed on the List of Explosive-Related Hazardous Chemicals and is an oxidizing solid. Follow the Hazardous Chemical Dart Board to learn more about hazardous transportation.
Magnesium nitrate hexahydrate is also counted as a hazardous chemical because the Catalogue of Hazardous Chemicals stipulates that, in addition to the listed entries, the inorganic salts category includes both anhydrous and compounds containing water of crystallization. However, Special Provision 332 of the UN Recommendations on the Transportation of Dangerous Goods makes it clear that magnesium nitrate hexahydrate is not subject to these rules.
Is ammonium bifluoride a dangerous good? What are the uses?
Ammonium hydrogen fluoride is a dangerous good.
Ammonium hydrogen fluoride is an inorganic compound, corrosive chemicals, white or colorless transparent rhombohedral crystal system crystals, moisture, water decomposition of toxic fluoride, nitrogen oxides and ammonia gas. Dissolved in water as a weak acid, can dissolve glass, slightly soluble in alcohol, very soluble in cold water, aqueous solution is strongly acidic, sublimation at higher temperatures, can corrode glass, corrosive to the skin, toxic. Ammonium Hydrogen Fluoride is mainly used in aluminum profile industry, lamps and lanterns industry, glass industry, picture tube industry, fluorine gas production, petroleum industry, electroplating industry, rare earth industry, boiler cleaning and exterior wall cleaning and other industries.
Salcon Chemical-Ammonium Hydrogen Fluoride Products
Common uses of ammonium hydrogen fluoride
1、Used as glass matting, frosting, etching agent (often used in conjunction with hydrofluoric acid).
2、Used as chemical reagent, disinfectant and antiseptic in fermentation industry, solvent for beryllium oxide to make beryllium metal, and surface treatment agent for silicon steel plate.
3、Used for cleaning and descaling of boiler feed water system and steam generating system.
4、It is used for acidizing the surface of oil field sand and gravel. When acidizing the formation in oilfield, ammonium hydrogen fluoride is added into hydrochloric acid to generate hydrofluoric acid, which is indirectly formulated with hydrochloric acid to form earth acid. This kind of earth acid treats grey rock, due to the generation of a protective layer of calcium fluoride insoluble in hydrochloric acid on the pore surface, the dissolution rate of the rock is significantly reduced to increase the depth of acidification, and when treating sandstone, it can prevent the generation of fluorosilicates caused by hydrofluoric acid, and at the same time, it strengthens the ability to dissolve silica compounds and well-wall muds, which enhances the effect of acidification, and reduces the corrosion of the surface equipment and pipelines.
5、Used in electronic industry, Braun tube (cathode picture tube) cleaning agent.
6、Used in the production of incandescent lamps, bulb inner surface matting agent.
7, used as alkylation, isomerization catalyst components.
8、Used as the intermediate of cryolite production.
9、Used as wood protection agent, preservative.
10、Used as the catalytic effect in electroplating, the reaction generates white substance anode mud.
11、Used in acid etching treatment of aluminum profile surface, forming fluoride protective layer on the surface.
12、Used in the manufacture of magnesium and magnesium alloy, oxidizing agent for the manufacture of aluminum and magnesium alloy.
13、It can remove the alkali residue on the fabric after alkaline washing, and it can also generate colorless and soluble ammonium iron fluoride with iron, which can be used to remove rust on the fabric.
14、Used as analyzing reagent and bacterial inhibitor.
15、Used as reagent for extracting rare elements. Citric acid-ammonium hydrogen fluoride leaching cobalt in iron ore tailings.
16、Used in the manufacture of welding rods, cast steel and so on.
17、It can be used as a hidden reagent of trivalent iron ions.
18、Mordant for fiber.
19、Used in the manufacture of ceramics.
20、Electronic grade ammonium hydrogen fluoride can be used in the semiconductor industry.
