The main producing area of aluminum foil bag

by：Kolysen 2021-01-16

060 aluminum foil bag components do not for a hot freedom of 060 enhanced the distortion of the pure aluminum, its corrosion resistance, pressure processability and excellent welding function, strength is not high. During the whole production process of intaglio text design overview of the mass and heat sealing glue layer to achieve strength protective layer of adhesive properties and the drying temperature and the coating machine running speed, tension control is in the process operation need harsh master. Can respond to shorten the heat preservation time. 10 and 20 iron scale solution containing fe30 cm3. 1摩尔压力; dm - 3 in the above style freedom of the scale of the secondary and tertiary reagent. Under the precondition of the etching can show differences in the meantime to feature to depict the grain boundary and the corrosion pit in the weave of the number of fission integral quantitative analysis. 3 sample etching provided a kind of reagent etching temperature 05 time 050 s. Modern cold rolling mill and foil rolling mill fire causes, such as electrostatic sparks, broken belt, bearing lubrication bad or damaged, incorrect operation, fire work, electrical spark, temperance ark inside wiring overheating, etc.

2 white dot defect analysis in micro not beautiful not beautiful micro organization of indecent view analyzes operation metallographic microscope, scanning electron microscope and energy spectrometer on thickness of 0. 055 mm white point defects of 060 aluminium foil bag of om, sem and chemical composition of indecent view, analysis and determination.

the om analyze the need for aluminum foil bag profiles mechanical polishing, etching liquid, and the sem and energy spectrum analysis to sample after polishing. Reasonable choice, heating temperature and holding time can get the good product quality, high production efficiency, less consumption of energy. Try rolling procedures are shown in table 3 passes general bake, temperature control at 171 ℃ advisable. Is the dislocation outcrops in the each grain is preferred etching and according to its address grain orientation according to the characteristics of the differences of erosion. The chemical composition of a certain enterprise produces 060 foil and quality score each element are shown in table. Correct use of sealing machine guarantee premise for normal operation of the machinery, is also to ensure that the enterprise product quality problem. The good news is that the number of the eve of the enterprise to the ehs idea has enough familiar, of not doing enough, is really to do, head-on. The curve suggests the purity of aluminum coating speed, tension and coating thickness and coating adhesion qualitative analysis in the process of coating the coating thickness of the glue layer of plastic PVC plate bonding steady level influence the glue layer of the eve of the coating is too thin, when hot-pressing PVC plate for lack of material and reduce the adhesive fastness glue layer too thick coating not only add to the cost and drying time should be extended in should be moderate in the thickness of the proper size of glue layer thickness of coated adhesive concentration, tension of coating, coating speed, the influence of the anilox roller line number.
