For the current aluminum, many aluminum materials can understand what is necessary to understand the process. To understand the relevant characteristics, in the production of aluminum profiles, the measuring tools are like weapons in the hands of the inspectors. If the weapon is in a semi-defective or damaged state, the test results have no meaning and there is no supervisory control over the quality of the product. Therefore, the maintenance and care of measuring tools is very important. Below are the maintenance specifications for several measuring tools. 1. The measuring instrument should be kept clean and dry, free from vibration and corrosive gas, and away from places with large temperature variations or places with magnetic fields. The measuring instruments stored in the measuring bo...

Aluminum foil can be divided into industrial aluminum foil and packaging aluminum foil. Industrial aluminum foil has a relatively pure chemical composition and a thickness of 0.005 to 0.2 mm. It is mainly used as a capacitor, heat insulating material and moistureproof material for the electrical industry and the electronics industry. The thickness of packaging aluminum foil is generally 0.007 ~ 0.1 mm, and there are various products such as flat foil, printing foil, color printing foil and crepe paper aluminum foil, which are mainly used as packaging materials for food, tea, cigarettes and the like. The aluminum foil is produced by the belt production method to a minimum thickness of 0.0025 mm and a width of 1800 mm. The aluminum foil is rolled without roll seam rolling, and the rolls are ...

Aluminum products that are bought at home often rust for a while and will see residue on the surface. Below, Jiahua Aluminum tells you how to maintain aluminum products: (1) Do not store long-term storage of sauce, vinegar, salt and other acids and alkalines in aluminum products, because acid, alkali and salt have corrosive effects on aluminum. Don't leave leftovers in it for a long time. (2) Do not stick the bottom of the pot to the red coal when cooking. When the aluminum pan is not water, it can't be dried, otherwise the bottom of the pot will be uneven. (3) The newly purchased aluminum pan, the first time you use it, it is best to porridge first, do not boil water and steamed steamed bread first, because the iron and salt in aluminum and water will react in a series of chemical reactio...

Control the thickness difference of aluminum foil The difficulty in controlling the thickness deviation is a feature of aluminum box rolling. The thickness difference of 3% is not difficult to control in the production of sheet and strip, but it is difficult to control in the production of aluminum foil. As the thickness of the aluminum box is reduced, its trace conditions can affect, such as temperature, oil film, oil and gas concentration. A roll of aluminum foil can reach several hundred thousand meters, and the rolling time can be as long as about 10 hours. The error of thickness measurement is easy to form with time. The only way to adjust the thickness of the aluminum foil is tension and speed.These factors all contribute to the difficulty of thick control of aluminum foil rolling.Th...
