Glass stress control is an extremely important link in glass production process. The method of applying appropriate heat treatment to control stress has been well known by glass technicians. However, in order to accurately measure the glass stress, the glass stress detector specially provided by Shenzhen Dongyi Precision Equipment Co., Ltd. is needed to complete the test. The glass stress detector is named after the application of polarized light interference principle to check the internal stress of glass. It is specialized in detecting the stress index of glass bottles, and can be used to detect the stress index of glass containers such as ampoules, vials, infusion bottles, wine bottles, jars, cosmetics bottles, and to control the quality of glass bottles.
 
Today, Dongyi Seiko introduced the commonly used quantitative polarization stress meter in detail, hoping to help everyone.
 
1、 Purpose and scope of use
ration Polarization stress meter It is an instrument that applies the principle of polarized light interference to check the internal stress of glass transparency or crystal birefringence effect. Since the instrument is equipped with incandescent light, sodium light, sensitive plate (full wave plate) and applies the 1/4 wave plate compensation method, the instrument can not only qualitatively or semi quantitatively measure the internal stress and distribution of glass according to the interference color sequence in the polarization field, but also accurately and quantitatively measure the value of the internal stress of glass. The instrument is suitable for optical factories, glass factories, glass products factories and laboratories, Measuring the stress value of optical glass, glassware and other transparent materials is not only widely used in industrial production, but also plays an important role in national defense, building materials geology, mineral materials and science. At the same time, the quantitative polarization stress instrument is also a special educational experimental equipment of various colleges and universities.
 
2、 Main technical data
1. Measurement accuracy ± 4nm
2. Diameter of polarizer φ 150mm
3. Workbench rotation angle 0-360 °
4. Wavelength of full wave plate: 565nm
5. Check the polarizer scale 2 °
6. Instrument weight 23Kg
7. The overall dimension of the instrument is 450mm long * 470mm wide * 700mm high
 

3、 Precautions for maintenance and use of quantitative polarization stress meter
1. It should be stored in a dry laboratory for use. Indoor moisture-proof, dust-proof and anti-corrosion gases should be covered with a dust cover when not in use.
2. In order to ensure the measurement accuracy, it is necessary to ensure that the indoor temperature is stable and the sample cannot be touched during measurement, so as to avoid thermal stress affecting the measurement accuracy.
3. The surface of each optical part in the instrument shall not be touched or wiped by hand. If there is dust, it can be gently brushed off with a brush. If there is oil stain on the surface of the optical part, it can be gently wiped off with absorbent cotton and alcohol ether mixture.
4. The instrument shall be prevented from violent vibration during use and handling.
5. In order to avoid overheating of electrical components, the instrument needs to be shut down for 10-15 minutes after 2 hours of continuous use, so as not to reduce the service life of the instrument.
 
The above is the sharing of Shenzhen Dongyi Precision Equipment Co., Ltd. on "quantitative polarization stress meter parameter data and precautions for maintenance and use". Glass stress detection is very important in glass quality detection. Shenzhen Dongyi Seiko Equipment Co., Ltd. specializes in the supply of stress testers, glass stress testers, Japanese original stress testers, fsm-6000le surface stress testers and other stress detection equipment, and provides professional laboratory solutions and equipment support services.
