Etchant and cleaning agent; Niche applications; HF boils near room temperature, much higher than other hydrogen halides. Title mixtures are treated with a silicon-containing compound, namely alkali metal silicate, preferably liquid soda glass, wherein hydrogen fluoride is directly converted into corresponding metal hexafluorosilicate insoluble in nitric acid-nitrogen oxides mixture. GUIDELINES IN CASE OF EXPOSURE WITH HYDROGEN FLUORIDE (AHF) AND HYDROFLUORIC ACID (HF) 7 Concen- tration % CLP CLASSIFICATION CLP –Classification, Labelling and Packaging ADR / RID CLASSIFICATION ADR - European Agreement on International Carriage of Dangerous Goods RID … Quick navigation Gas Detectors and Sensors Tubes Masks and Filters Suits. 0000019809 00000 n 0000003000 00000 n Reflecting the ability of HF to participate in hydrogen bonding, even proteins and carbohydrates dissolve in HF and can be recovered from it. 0000022068 00000 n 2. Overview Hydrogen fluoride (HF), also known as hydrofluoric acid, is used primarily for metal cleaning and etching in Massachusetts. Use self-contained breathing apparatus and gas-tight suits to prevent exposure to gas and vapour. They are a powerful driver of clean hydrogen applications in transport, where diesel and petrol are rapidly becoming less acceptable. Ammonium hydrogen fluoride* (NH4HF2) is used for aluminium anodization, metal surface treatment, manufacture of wood preservatives, glass processing, building protection, mineral oil/ natural gas drilling, cleaning of industrial plants and in the electronic industry. Precautions for safe handling. Background and comparative information on the four basic processes currently in use are discussed. %%EOF 0000010028 00000 n The acid was found to contain up to 0.1 ppm of remaining fluorine. 0000018158 00000 n Fluoride-ion cleaning, using Hydrogen Fluoride gas as the active agent, is rapidly becoming established as a cost effective method to prepare nickel and cobalt based superalloys for braze repair. HF gas can be toxic if it escapes into the atmosphere. Hydrogen Fluoride Ion Cleaning. It is produced commercially by action of sulfuric acid on the mineral fluorspar. The photo above shows the remains of a cylinder that ruptured as a result of this reaction. 0000009684 00000 n The DFIC process, also known as hydrogen fluoride (HF) ion cleaning, results from the reaction of fluorine with various oxides. 0000044437 00000 n Suitable products for Hydrogen fluoride (anhydrous) HF. 0000036205 00000 n This substance has an industrial use resulting in manufacture of another substance (use of intermediates). 2. Fluorine - Fluorine - Production and use: Fluorspar is the most important source of fluorine. Reference to other sections 7.1. Vapor phase hydrogen fluoride ion cleaning (HFIC) was introduced in 1985 as a method to clean gas turbine superalloys. It was developed by a major jet-engine manufacturer as a cost effective repair process for nickel-base airfoil compo- 0000045838 00000 n 0000107612 00000 n 0000039820 00000 n At Ti-Coating, we are more than just our superior coatings, cleaning, and equipment; our products and services represent value-added benefits for you. 0000031842 00000 n Fluoride Ion Cleaning (FIC), synonymous with Hydrogen Fluoride (HF), Ion Cleaning has been proven to be a highly effective process for the removal of deeply embedded oxides from superalloys containing significant amounts of aluminum and titanium. Background and comparative information on the four basic processes currently in use are discussed. 0000011049 00000 n Hydrogen Fluoride Ion Cleaning HFIC is used to clean gas turbine superalloys. Hydrogen fluoride Accession Number DB11072 Description. A essentially anhydrous cleaning composition comprising 88 weight percent or more of a fluorinated solvent, from 0.005 to 2 weight percent of hydrogen fluoride or complex thereof, and from 0.01 to 5 weight percent of a co-solvent. Whether portable gas detectors, gas detection tubes or personal protective equipment - Dräger offers a comprehensive portfolio to protect you when handling hazardous substances.
