Real time concentration detector for sizing agent, digital remote stable monitoring

Product Introduction

Carbon fiber sizing agent is a polymer protective layer coated on the surface of carbon fibers, which mainly functions to bundle, lubricate, anti-static, and enhance the interface bonding between fibers and matrix resin. The concentration of sizing agent is the core process parameter that determines the sizing effect. A low concentration can lead to poor fiber bundling and increased fuzz, while a high concentration can cause excessive sizing and subsequent deterioration of the composite process interface. Therefore, precise control of the concentration of sizing agents in carbon fiber production lines is of great engineering significance.Real time concentration detector for sizing agentAs a concentration analysis instrument based on the principle of optical refraction, it can achieve continuous, real-time, and non-destructive detection of carbon fiber sizing agent concentration, providing reliable data support for automatic closed-loop control.

Real time concentration detector for sizing agentWorking based on the principle of total reflection critical angle detection. The LED light source inside the instrument emits light and reaches the sapphire prism. The prism comes into direct contact with the tested carbon fiber sizing agent, and light enters the liquid (low refractive index medium) from the prism (high refractive index medium). When the incident angle is greater than a certain critical value, the light undergoes total reflection, and the reflected light is received by a high-resolution CCD linear array detector. The size of the critical angle depends on the refractive index of the liquid, and the higher the refractive index, the larger the critical angle, and the position of the reflected light on the CCD also moves accordingly.

technical advantage

1. No pre-treatment of the sample, no need for reagents or consumables, the entire measurement process takes seconds.

2. A long-lasting light source that lasts up to 100000 hours, reducing usage and maintenance costs.

3. Optional components are available for fully automatic cleaning of the optical window to avoid measurement deviation caused by contamination.

4. Some materials are not affected by color, turbidity, or viscosity.

5. The algorithm ensures that some materials in the measurement results are not affected by bubbles, solid impurities, and crystals in the detection object.

6. Not affected by pressure changes, sudden changes in flow rate, or turbulence phenomena of the detected object.

7. The instrument has no mechanical action during the detection process, ensuring long-term stable use.

8. Detect the full planar structure of the prism to avoid dirt and grime accumulation in the optical window.

9. Factory calibration and automatic temperature compensation, directly put into use.
