Determination of microscopic morphology and diameter of chemical fibers Scanning electron microscopy1 ScopeThis standard specifies the use of scanning electron microscopy to observe the microscopic morphology of chemical fibers and test the fiber diameter. method. This standard is applicable to the determination of the microscopic morphology and diameter of various chemical fibers and their products. The determination of the diameter is only applicable to the fiber transverse Chemical fibers with a circular or nearly circular cross section, other materials may be implemented in accordance with this standard.2 Normative referencesThe following documents are indispensable for the application of this document.

The diameter of the fiber was measured by measuring the distance between the two edges of the longitudinal side of the individual fibers on the image. 5 instruments, tools and materials Instruments, tools and materials include. a) Scanned electron microscope that has been calibrated or calibrated. the resolution of the secondary electronic image is better than 20 nm, and the magnification is at least 30 times~ 20000 times; b) vacuum spray or sputter; c) Hastelloy slicers or other types of fiber cutters; d) scorpions, scissors, ear balls; e) copper or aluminum sample holders; f) conductive adhesive; g) Gold. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 36422-2018_English be delivered?Answer: Upon your order, we will start to translate GB/T 36422-2018_English as soon as possible, and keep you informed of the progress.
