This stress meter (polarization analyzer) is used for quality control and quality management of rough processing products.
The remarkable functions of the stress meter (polarization analyzer):
The crystallinity can be identified at any time.
, Not only can molecular birefringence streamlines (edges) be seen in terms of color, but when the rough-processed product forms an axis parallel to the opposite axis of the observer, black parallel tilt lines are visible. Parallel sloping lines indicate the direction of the original tension on the molecule.
When observing, a special and removable stage is provided to quickly obtain the correct pre-formed alignment.
In order to observe the edges, the rough-machined products are arranged at degrees opposite the axis and degrees are viewed as black isotropic lines.
This stage takes into account the rotation of the rough-processed product during observation. In addition to white light, sodium light is also used to test colored preforms or complete bottles.
In addition to detecting bottle preforms of various colors, the special polarizing stress meter (-) also has an analysis function that can analyze various conditions that occur during the production process of bottle preforms and provide solutions. (A color comparison picture of defects will be randomly attached for better analysis of the preform.)
Stress measurement requires specialized knowledge and testing skills, and the measurement results will be used to guide the production process or analyze the cause of product failure. , but also requires comprehensive knowledge and experience in production processes, production equipment, stress properties, usage requirements, stress analysis technology, etc.
