The first to know what is under the nozzle plate? Also known as spinning spinneret cap. The role of the nozzle plate is viscous polymer melt or solution flowing through pores into a specific cross-sectional shape of the thin stream, after solidification medium such as air or coagulation bath cured to form filaments.
      According to the type of fiber and different specifications, different specifications, shape, female, material and so on. Spinneret operate at higher temperatures and pressures. It requires pressure, corrosion resistance and sufficient mechanical strength.
      Spinneret can be divided into: (1) common type, which can be divided into the melt-spinning spinnerets (which has a circular shape, rectangular, fan) and wet spinning nozzle plate (also known as the spinneret); (2 ) is non-circular cross-sectional shaped spinneret, spun fibers; and (3) the composite to produce a composite fiber spinneret.
      Changzhou Shuanggudunda Electromechanical Technology Co., Ltd. developed the production of PSB-A spinneret detector is used to detect spinneret pore size, the amount of wear, dirt, a special instrument shaped pore size, it is simple high detection accuracy can be achieved by controlling the different light detection function.
      Detection methods:
      1 using computer control and image processing technology, automatic hole-by-scan testing, and test results are recorded.
      2 For unqualified spinneret instrument automatically records and automatically blow clean, laser positioning indicating the automatic cleaning and then he served as unqualified hole location.
