Introduction: Used to cut fibers or yarns into very small cross-section sheets to see the organization of the structure. Applicable standards: GB / T10685, ISO137 and so on. Specifications: Slice area 3 × 0.8mm Small slice thickness 20um Dimensions L82 × W27 × H25mm Operating procedures: ① loosen the screws on the slicer 4, remove the pin 5, the screw 6 and the metal plate 2 is turned to a vertical position (or removed), withdraw the metal plate 1; ② Randomly take a bunch of fibers, hand straight to straighten the flat, a certain amount of fiber into the metal plate 2 of the groove, the metal plate 1 is inserted, compacting the sample (in order to gently pull the fiber bundle moved slightly ), For some fine and soft fibers or easily deformed fibers (yarn) in the fiber bundle can be added a small amount of 3% collodion, make it fully penetrate between the various fibers, and then tighten the fibers. Or in the fiber bundle wrapped around a layer of wool fiber, in order to cut a better slice; ③ cut a sharp blade with the metal front and back of the fiber side; ④ Turn the screw 6 to the working position and position it with the pin 5. Tighten the screw 4 (at this time the lower end of the precision screw 3 pliers should be aligned above the fiber bundle); ⑤ clockwise rotation precision screw seat 3, so that the fiber bundle slightly out of the metal surface, and then exposed fiber coated with a thin collodion until the fire cotton glue dry, with a sharp blade along the metal surface cut The first piece of the sample (because the first piece of the thickness of the more difficult to control, generally abandoned without); ⑥ Repeat ⑤ steps until a thin and uniform sample slice; ⑦ on the sample slides on glycerol slides, cover slips, for microscopic observation.
