The main factors affecting the performance indicators of liquid crystal polarizers.
The main factors affecting the performance of the polarizer are related to the basic performance indicators of the polarizer.
The main factors affecting the optical performance of the polarizer include: the choice of polarizer material, the choice of dyeing material, the choice of polarizer dyeing, the choice of stretching process conditions and the limitation of equipment capacity. These all involve the core technology of polarizer production, Therefore, polarizer manufacturers are very cautious when choosing these materials and process conditions, and they are generally not easy to change. Once polarizer products are approved by customers, polarizer manufacturers will take strict production quality management measures to ensure the optical performance of polarizer products Stability.
The durability technical indicators of polarizer products actually include two durability indicators: the durability of the polarizing film and the durability of the pressure-sensitive adhesive. The main factors affecting the durability of the polarizing film include: the choice of the basic material of the polarizing film and the coloring material Selection, dyeing of the polarizing film, stretching and compounding process conditions, etc. Generally speaking, the higher the molecular weight of the polarizing film, the higher the stretch ratio, the better the durability of the polarizing film, and vice versa. At the same time, in production In the process, the better the chromaticity of the polarizing film, the stronger the anti-degradation ability of the dye used, and the better the durability of the polarizing film. Therefore, the durability of the dye polarizing film is much better than that of the iodine dyed polarizing film. It affects pressure sensitivity The main factors of adhesive durability include: the choice of adhesive formulation, the choice of adhesive solvent, the choice of adhesive mixing process conditions, the choice of adhesive drying process conditions and the choice of adhesive storage conditions. It should be noted that the durability of the adhesive index It is a comprehensive index, and its influence is diverse, and this is another core technology of polar production, which is determined by the general polypropylene sphere manufacturer under the adhesive process conditions. It will not be easily changed in the future, and it is strict. The quality management process requirements, otherwise it is easy to cause bad batches of products.
The main factors that affect the appearance of the polarizer are various. It mainly includes: environmental purification conditions for polarizer production, material selection for polarizer production, equipment conditions for polarizer production, process flow and formula for polarizer production, packaging, and polarizer The storage and transportation conditions of the film production, as well as the storage environment and processing methods of the polarizer used by the customer. In short, Aurora is a very "delicate" product, which must be carefully stored and used, otherwise it will easily cause surface pits, black spots and warping Surface defects.
