STRAIN VIEWER FOR PET PREFORMS (SPET-801) Product name: Strain viewer for PET preforms SPET-801 Specification: Viewing field:..............260 x 260mm Overall size: ...............445 x 280 x 280mm Mains voltage:............220/240v The function of this SPET-801 is to check dacron, PET preforms for crystallinity and other defects. This instrument is used to control the quality of PET preforms. The advantages of our PET preform strain viewer are: 1. Crystallinity is readily identified. 2. Not only can the molecular birefringent flow lines (fringes) be seen in colour, but also the black isoclinic lines are visible when the preform axis are parallel to the polarising axis of the viewer. The isoclinic lines indicate the directions of the molecular orientational strains. 3. A special and removable stage is provided to rapidly obtain the correct alignments of the preforms when viewing. For observations of the fringes the preforms are aligned at 45 degrees to the polarising axis and at 0 degrees to view the black isoclinics. The stage allows for the rotation of the preforms whilst viewing. Sodium light is also provided, in addition to white light, for the examination of coloured preforms or completed bottles. The SPET-801 can not only check all colours of PET preforms, but also has 12 analysis functions. It can analyze all situations occurring in production process and provide solutions to these problems. (The instrument is accompanied by 12 coloured and defective pictures of contrast, in order to analyze PET preforms better.) Specialized knowledge and test techniques are required in strain measuring. And the result of measuring can be used to direct production process or analyze the reason of product failure. |
