Relationship between quality of aluminum foil wool and pinholes From the quality of internal aluminum foil wool, imported wool is generally a compound, mainly β and α phases of FeSiA, but domestic aluminum foil wool is mainly dominated by FeSiAa phase and FeAl3. Compound. The a phase of FeSiA is a relatively ideal compound, which is very easy to be broken. FeAl3 belongs to the coarse compound phase, which is the main factor leading to the number of pinholes. Since it has a double-zero aluminum foil thickness of 6~7um, as long as it is a second direction larger than 5um. Pinholes will appear, but the smaller the crystal grains, the better. The grain size less than 1um will increase the work hardening rate, which will increase the deformation resistance and reduce the plastic deformation abi...

Aluminum panels are now widely used in the construction industry, especially for building materials. Therefore, the aesthetics of the aluminum plate is more concerned. So now more  Aluminium foil manufacturers are more concerned about the aesthetic treatment of aluminum panels. Electrophoretic painting This method of treatment is currently used in Japan. After such treatment, the surface of the aluminum sheet has a smooth surface and the corrosion resistance is enhanced. 2. Powder electrostatic spraying The main feature is the enhanced corrosion resistance of the aluminum sheet. For some acid-base salts, this aluminum sheet is superior to the oxidized coloring profile. 3. Frosted fabric The aluminum plate of the pattern itself is very bright, but in our life, there will be interference hig...

First, aluminum foil active slitting That is, the round blade is rotated by the foil material, which is the same way as the razor blade, except that there are more cutting edges in contact with the material. In this way, since the blade itself is passive, it is affected by the speed of the material, and the contact point and the knife edge are pressed. The material winding is bounced. Because the blade itself has no power, the fluctuation of the winding is easy to warp. Second, the circular knife active cutting This is the most versatile way at the moment. There are two types of circular cutter active slitting, one is coaxial rotation and the other is single-arm motor drive. The one-arm drive is more suitable, which adjusts the blade speed depending on the thickness of the material. In the...

Appropriate amount of desiccant (dry oil) is added in the aluminum foil lunch box printing ink. Appropriate addition of desiccant can achieve certain effects. The desiccant is appropriately added to the ink, and the wicking action of the ink can accelerate the oxidation and polymerization of the ink layer, promote the drying and solidification of the ink layer, and prevent the occurrence of sticky defects. However, the desiccant should not be added excessively, otherwise the object must be reversed and converted to the opposite side. It can not only achieve the purpose of improving the fixing speed and dryness, but also causes the ink to dry too fast, dry, dry, or even in the printing process. print. In addition, it may cause an increase in the viscosity of the ink during the printing proc...
