Jakie właściwości muszą sprawdzić powłoki światłowodowe? Specyficzna metoda wykrywania
Powłoka światłowodowa jest rodzajem specjalnej powłoki stosowanej w dziedzinie komunikacji światłowodowej, its main function is to protect and enhance the mechanical strength and optical performance of optical fiber, while reducing the loss and failure rate of optical fiber, improve the reliability and stability of optical fiber communication. Fiber coating is usually a polymer material that can be deployed and customized according to different application scenarios and requirements. In the optical fiber manufacturing process, the optical fiber coating is coated on the surface of the optical fiber, after high temperature drying and curing treatment, forming a hard, gładki, odporny na zużycie, corrosion-resistant protective film, so that the optical fiber has better mechanical properties such as tensile resistance, odporność na ściskanie, bending resistance, and can effectively reduce the loss of optical fiber transmission signal.

Metoda wykrywania
The following is a detailed description of the test method for the performance parameters that need to be tested for optical fiber coatings:
Tensile resistance: Use a tensile testing machine to measure the failure strength of the coating under tensile force, or use a peel tester to measure the adhesion strength of the coating and the optical fiber surface.
Odporność na zużycie: Wear test is carried out with a wear tester to simulate the durability and wear degree of the coating under different wear conditions.
Właściwości optyczne: Use spectrometers, microscopes and other equipment to measure optical parameters such as light transmission, reflectivity and refractive index of the coating to evaluate the effect of the coating on optical signal transmission.

Corrosion resistance: salt spray test, corrosion test and other methods are used to simulate the corrosion resistance of the coating in different acid-base environments.
Stabilność termiczna: A thermogravimetric analyzer is used to measure the thermal stability and thermal decomposition characteristics of coatings at high temperatures.
Viscosity and flow properties: Use viscometers, rheometers and other equipment to measure the viscosity and rheological properties of the paint and evaluate the flow and uniformity of the paint.
Stabilność przechowywania: The storage stability test of the paint is performed to evaluate the stability and quality retention of the paint in long-term storage.

Przypominamy: różne parametry wydajności mogą wymagać różnych metod testowania i sprzętu, mogą też obowiązywać pewne standardy i specyfikacje branżowe, for the performance of optical fiber coating detection, you should also choose the corresponding detection methods and standards according to actual needs. W tym samym czasie, in order to ensure the accuracy and reliability of the test, it is necessary to strictly control the test conditions and standardized operations during the experiment.
