The Research Of Qulity Of The Polyamide Resin For Bi-oriented Film

PA6 slice production is two-way stretch nylon membrane (BOPA) of the base material, BOPA film has an outstanding tensile strength, impact strength and anti-piercing intensity, good gas barrier, excellent heat resistance, and the fog of gloss And the good of the characteristics of the printable, able to multi-layer film composite form of flexible packaging products. In food packaging, medical packaging, industrial materials and electronic packaging has a wide range of uses.Domestic manufacturers with a slice of film production and sales while nearly three years of history, but the film section with the quality and stability has been insufficient. There is no fundamental reason for the establishment of internal quality slice detection methods and quality control targets, resulting in the factory section of the inadequate understanding of the inherent quality. Also due to the lack of improvement in the quality of the establishment of internal slice detection method, and the impact of the installation process optimization and quality optimization.Find information and the author of sections of the track and try to determine the reasons for the rupture of membrane because the section containing gel particles, slice, high-oligomers, molecular weight distribution caused by factors such as uneven. After the market test, the film itself with slices of high-quality requirements, in addition to the general section of the conventional analysis, there are a number of key indicators to the quality of testing. Therefore, the timely two-way stretch film material with the other slice of the quality of projects:gel particles; cyclic oligomer; molecular weight distribution; ash; oxidation; crystallinity; Tm,â–³H, such as tracking quantitative analysis, to increase monitoring Frequency, adjusted for the production process to provide strong theoretical basis at the same time the quality of data to track, develop indicators of the quality control section to ensure that two-way stretch film with PA6 slice base material quality and very necessary.This article embarked based on the two-way stretch membrane craft production, studies has become the membrane craft and the membrane quality with its PA6 parent metal quality corresponding relationships, simultaneously, through screened many kinds of parsing techniques, to affected the high polymer material quality the related content to carry on studies item by item, has screened the massive analysis method, has obtained the volume test data, and based on this, carried on has analyzed one by one, proposed the two-way stretch membrane used the PA6 slice parent metal the quality control target and the enterprise standard (proof edition).Based on this research, two-way stretch film with PA6 slice of materials and two-way stretch film manufacturers are stable product quality, access to a better economic efficiency.
