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 unit of this standard. China Lokai Group Co., Ltd. The main drafters of this standard. Jiang Ning, Jiao Congxuan, Xia Jiangnan, Gao Jianhui. Optical function film cellulose triacetate Method for retardation of ester (TAC) film

1 Scope

This standard specifies the method of measuring the retardation of the cellulose triacetate (TAC) film by rotating photon method, including the determination of the retardation of the surface phase And the thickness of the two parts of the delay. This standard is applicable to the triacetate cellulose ester (TAC) film produced by the casting process.

2 terms and definitions

The following terms and definitions apply to this document. 2.1 Strain strain The deformation of the unit length is divided into the permanent plastic strain introduced in the manufacturing process and the elastic strain in the presence of stress. Strain will produce strain birefringence and phase delay. 2.2 Optical axis azimuthal aperture Twist angle The sample main strain slows the direction of the slow axis with the sample TD (the direction of the film on the manufacturing equipment is called the MD direction, perpendicular to the direction of the MD Called the TD direction, that is, the transverse direction of the web). 2.3 Delay retardation Relative delay amount The distance between the two waves after the light passes through the birefringent material. 2.4 Surface retardation Re Due to the anisotropy of the refractive index in the XY direction of the film, the amount of retardation generated. 2.5 Thickness retardation Rth The amount of retardation generated due to the anisotropy of the refractive index in the XY direction and the refractive index in the externally externally Z direction.

3 test equipment

3.1 micrometer or thickness gauge The micrometer or thickness meter to be used shall meet one of the following conditions. Test absolute accuracy ≥1μm or relative accuracy ≥1%.
