For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. JB/T 9797-1999 Sprayer spray parts3 Applicable objectPaper, natural wood, non-woven fabrics, light-colored dense textiles and other penetrating surface of the surface of the dust traces, and light-colored tiles and other non-permeability The surface of the surface of the plane dust traces.4 principleHydrochloric acid reacts with iron in the dust to form ferrous chloride. Ferrous chloride reacts with potassium ferricyanide to form a precipitate of "Teng's Blue" Color and enhance the dust footprint, the reaction is as follows. FeO 2HCl = FeCl2 H2O 3FeCl2 2K3 [Fe (CN) 6] = Fe3 [Fe (CN) 6] 2 ↓ 6KCl5 reagents and equipment5.1 Reagent The following reagents are chemically pure. a) concentrated hydrochloric acid; b) Ethanol; c) potassium ferricyanide; d) deionized water; e) Dust fixative, refers to a special kind of dust fixative or styling hair gel and other resin-based polymer alcohol solution as the main component of the liquid. 5.2 equipment sprayer. Sprayer spray components should be acid and alkali, the technical requirements see JB/T 9797-1999. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GA/T 936-2011_English be delivered?Answer: Upon your order, we will start to translate GA/T 936-2011_English as soon as possible, and keep you informed of the progress.
