Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed by the China Petroleum and Chemical Industry Association. This standard by the National Optical Functional Film Materials Standardization Technical Committee (SAC/TC431) centralized. The drafting of this standard. China Le Kai Group Co., Ltd., Hefei Le Kai Technology Industry Co., Ltd. The main drafters of this standard. Jiao Congxuan, Li Xiuzhen, Jiang Ning, Xu Lili. Optical function film surface hardening film Hardness layer thickness determination method

1 Scope

This standard specifies a method for the determination of the thickness of a hardened film coating using a reflection interference spectroscopy. This standard applies to polyethylene terephthalate (PET) as the substrate of the polyester film, in its surface coated with a single layer of transparent hardening layer The thickness of the measurement. The measurement of the thickness of the transparent coating on the surface of the film with other materials is also referred to.

2 terms and definitions

The following terms and definitions apply to this document. 2.1 Coherent light coherentlight The light that satisfies the coherent condition. The coherent conditions include. (1) the same frequency of the two beams; (2) the vibration direction of the two beams is the same; (3) The vibration of the two beams has a constant phase difference. 2.2 Optical path difference opticalpathdifference The two coherent lights from the same point of light are subjected to different optical path distances encountered at a certain point of encounter. Indicated by Δ. 2.3 Phase difference phasedifference The two coherent lights from the same point of light are subjected to different optical paths at a certain point where the two beams of coherent light vibrate at the phase Poor, indicated by δ.

3 principle

As shown in Fig. 1, by using the principle of light interference, by analyzing the reflected coherent light generated by the vertical incident light at the upper and lower interfaces of the coating, The thickness of the hardened layer is measured by calculating the optical path difference between the two beams of light passing through the upper and lower interfaces of the coating. Description. 1 - incident light; 3 --- transmitted light; 2 --- Reflected light; 4 --- hardened layer. Fig.1 Schematic diagram of reflection spectrum ......
