Introduction
GB/T 37384-2019 Standard Overview
This standard specifies the technical requirements, test methods, inspection rules, and labeling, packaging, transportation and storage of triacetate cellulose (TAC) for optical functional films.
Background and significance of standard formulation
Optical functional films have important applications in modern science and technology, such as polarizers, filters and other fields. As its key raw material, triacetate cellulose (TAC) directly affects the optical properties and stability of the film. Therefore, the formulation of unified technical standards is crucial to ensure product quality and promote industrial development.
Comparison of Technical Requirements
| Item | Indicator |
|---|---|
| Water (mass fraction)/% | ≤2.0 |
| Acetylation value (in terms of CHCOOH) (mass fraction)/% | 60.5~61.1 |
| Viscosity/s | 9±2 |
| Dissolution state | Transparent, free of gel and fiber |
| Free acid (in terms of CHsCOOH) (mass fraction)/% | ≤0.01 |
Implementation suggestions
Raw material procurement:It is recommended to select suppliers with stable production capacity and require them to provide product quality certification documents.
Quality control:Establish a complete laboratory testing system to ensure that all indicators meet the standard requirements.
Process optimization:According to the test method, optimize key process parameters such as dissolution and hydrolysis to improve product consistency.
Storage conditions:Store in strict accordance with standard requirements, avoid high temperature and high humidity environment, and ensure stable product quality.
