Các nhà máy sản xuất lá nhôm khi gia công lá nhôm sẽ đặc biệt chú ý đến các chi tiết sau:
Làm sạch: Lá nhôm rất nhạy cảm với tạp chất, bất kỳ bụi, dầu hoặc các chất gây ô nhiễm khác sẽ ảnh hưởng đến chất lượng và hiệu suất của lá nhôm. Vì thế, trước khi gia công lá nhôm, xưởng sản xuất, equipment and tools must be thoroughly cleaned to ensure that there is no contamination by impurities.
Temperature: The manufacture of aluminum foil needs to be maintained at a proper temperature. High temperatures can soften aluminum foil, while low temperatures can embrittle it. Vì thế, it is necessary to control the temperature during processing to ensure the quality of aluminum foil.
Pressure: Foil processing requires proper pressure to make the foil tough and elastic. Too high or too low pressure will affect the performance of aluminum foil. Vì thế, the staff needs to adjust the processing pressure according to the material and thickness of the aluminum foil.
Bôi trơn: Processing aluminum foil requires lubricants to reduce wear and friction. The type and amount of lubricant also need to be adjusted according to the material and thickness of the aluminum foil.
Inspection: After the aluminum foil processing is completed, strict inspection is required to ensure that the aluminum foil is free of any defects or damage. This includes the inspection of appearance defects, dimensional accuracy, flatness and other aspects. Only aluminum foils that pass the inspection can be considered qualified products.
Khi mua giấy nhôm, you should pay attention to the following product details:
độ dày: The thickness of aluminum foil has different requirements for different applications, so you should pay attention to the required thickness when purchasing and choose the right product.
Width and length: The width and length of aluminum foil should also be selected according to needs. Some foils may be too short or too narrow for specific needs.
Bao bì: Aluminum foil is usually sold in rolls or stacked in boxes. At the time of purchase, the packaging should be inspected to ensure that the foil has not been contaminated or damaged.
Surface Flatness: The surface flatness of aluminum foil is very important for some applications, chẳng hạn như bao bì thực phẩm. When purchasing, you should check whether the surface of the aluminum foil is flat, without obvious depressions, waves or wrinkles.
Sạch sẽ: Lá nhôm rất nhạy cảm với tạp chất. When purchasing, you should check the surface of the aluminum foil for dust, oil or other contaminants to ensure the quality and performance of the aluminum foil.
Vật liệu: Aluminum foil can be made of different materials, such as pure aluminum, hợp kim nhôm, vân vân. When purchasing, you should pay attention to the required materials and choose the right product.
