The instrument can meet the requirements of long-term online detection of heat resistance and creep resistance of chemical fiber high-strength filaments under different temperature conditions.
★★★Detect three key indicators:
1. Creep elongation
2. Creep rupture time
3. Heat resistant temperature
The detection range can cover the existing heat resistance, creep resistance, and heat resistance chemical fiber high
The related technical evaluation of strong filaments, other organic high-performance fibers and their composites can also be used for reference. It is suitable for production, application, testing departments and scientific research institutions.
1. Main technical features
The instrument adopts 6-station design, which can test 6 samples at the same time. The equipment meets the continuity requirements of temperature, force value loading, time measurement, etc., and can ensure online real-time monitoring of creep performance for a long time in high temperature environment, so as to truly and accurately reflect the heat resistance and creep resistance of chemical fiber high-strength filaments. The application field, especially the prediction of major projects, provides detection basis.
In order to ensure that the product can work stably for a long time, redundant design is adopted in important technical links. The failure of any node will not affect the test, and it can provide stable testing for at least three years without interruption.
1. Stable and reliable constant temperature design to ensure high temperature test environment
The constant temperature device adopts blast circulation and intelligent PID control to achieve uniform and precise constant temperature in the box, and the temperature control accuracy is ±0.2 °C. Among them, the heating device is a consumable item, so the redundant design is adopted for the heating device.
2. Artificial intelligence recognizes creep length, stable, reliable and high precision
Under the environment of room temperature -200 ℃, it is connected to the server through a high-resolution industrial camera. Relying on the professional analysis software independently developed by the company, the creep length is fully automatically and intelligently recognized, and the cursor is automatically tracked and positioned, with a range of 30cm±0.01cm. The detection data is stored in the database, and the user can customize the sampling period and display period.
Industrial camera pixel: 5 million, intelligent identification creep length accuracy: 0.01mm.
3. The force value loading uses high-precision force value sensors, and the computer sampling system automatically identifies the current creep force values of the 6 stations
The chemical fiber high-strength filament is loaded by a precision force sensor and controlled by a computer. Taking into account a series of factors such as system stability, it relies on the electronic circuit board and professional software independently developed by the company to track in real time, and automatically identify the current loading force value and display it on the screen. displayed and stored in the database.
The force value sensor adopts 24-bit high-precision AD sampling, with good linearity and display accuracy of 0.005N.
