Embodiment 1

[0069] Preparation and use of a serpentine asbestos (chrysotile) standard test piece for a polarizing microscope:

[0070] Take one of the slides, clean the surface with water and dry it. Select a suitable area and cover the corrosion device; use a clean brush to pick up an appropriate amount of hydrofluoric acid, and apply it to the hollowed out position of the corrosion device. After 5 minutes, it was observed that there was corrosion on the glass surface, and the corrosion device was removed, and the surface of the glass slide was cleaned immediately with clear water. The surface of the slide glass is corroded, and the fixation area, the dipping area and the slide area can be distinguished. Transfer 200 microliters of the asbestos standard substance solution to the slide area, and let it dry naturally.

[0071] Add a certain amount of neutral gum dropwise on the fixed area, the amount is enough to cover the fixed area, cover with the cover glass and compact it. Then natu...

Embodiment 2

[0074] A method of making and using a standard test piece of amphibole asbestos (anthophyllite, tremolite, actinolite, crocidolite, amosite, etc.) for a polarizing microscope:

[0075] Take a glass slide, clean the surface with water and let it dry. Select a suitable area and cover the corrosion device; use a clean brush to pick up an appropriate amount of hydrofluoric acid, and apply it to the surface of the corrosion device and the hollowed out position. After 10 minutes, the corrosion device was removed, and the surface of the glass slide was immediately cleaned with water. The surface of the slide glass is corroded to form the fixed area, the dipping area and the observation area. Transfer 500 microliters of the asbestos standard substance solution to the slide area, and let it dry under light. A certain amount of neutral gum is dropped on the fixed area 3, covered with the cover glass, and compacted. Then accelerate curing under light, and then make standard test piece...

Abstract

The invention discloses an asbestos standard test piece preparation device for a polarizing microscope and a test piece preparation method. Corresponding areas of the glass slide are corroded through a polytetrafluoroethylene corrosion device, and a corresponding fixing area, a corresponding dipping area and a corresponding slide area are prepared. A prepared asbestos standard material solution is transferred into the slide glass area to be dried, neutral gum is dropwise added into the fixing area to fix the cover glass, the prepared standard test piece is not prone to falling off, and the safety of testers is guaranteed; in the using process, impregnation liquid can be dropwise added at any time, it is guaranteed that the refractive index and other optical properties of the impregnation liquid are not changed, and then the accuracy of a test result is guaranteed. After the test is finished, the impregnation liquid is sucked out, and the asbestos standard test piece can be stored and reused next time, so that the analysis and detection cost is reduced.

Description

technical field [0001] The invention relates to an asbestos inspection and testing technology, in particular to a preparation process and a use method of an asbestos standard test piece for a polarizing microscope. Background technique [0002] Asbestos is a general term for a variety of silicate minerals. It is an important mineral raw material and has been widely used in transportation, chemical industry, construction, metallurgy, etc. in history and now. Specific characteristics of asbestos material is fibrous structure, and can be torn into fine and flexible fibrous material. Asbestos substances mainly include serpentine asbestos (chrysotile) and amphibole asbestos (anthophyllite, tremolite, actinolite, crocidolite, amosite, etc.). [0003] Because asbestos has excellent physical properties such as chemical corrosion resistance, heat resistance, heat preservation, insulation, and wear resistance, it can be processed into textiles for use. According to relevant literatu...
