অ্যালুমিনিয়াম ফয়েল শ্রেণীবিভাগ

Aluminum foil generally refers to a rolled product with a thickness less than 0.2mm and a rectangular cross-section. যাহোক, the thickness boundaries in different countries are not exactly the same (টেবিল 1-1), and there are more and more aluminum foils below the thickness limit.

Classification method of aluminum foil

অ্যালুমিনিয়াম ফয়েল শ্রেণীবিভাগের অনেক উপায় আছে. তারা বেধ অনুযায়ী শ্রেণীবদ্ধ করা যেতে পারে, আকৃতি, অবস্থা, উপাদান বা অ্যালুমিনিয়াম ফয়েল প্রয়োগ.

The classification dimensions we often see are material, thickness and application. During our communication with customers, customers usually have the following requirements:

Real customer inquiry information

Through the above real customer demand information, we understand that customers usually point out the alloy, thickness or use of the required products, which means that these three indicators are very important to customers;

অবশ্যই, there is a certain correlation between these three indicators. উদাহরণস্বরূপ, 10-20 microns width 30cm 8011 aluminum foil is generally a পরিবারের অ্যালুমিনিয়াম ফয়েল;

Classification of aluminum foil by thickness

Aluminum foil can be divided into thick aluminum foil, single zero foil and double zero foil according to thickness difference.

• ① Thick aluminum foil: Aluminum foil with a thickness of 0.1~0.2mm.
• ② একক শূন্য ফয়েল: foil with a thickness of 0.01mm and less than 0.1mm.
• ③ Double-zero foil: The so-called double-zero foil is a foil with two zeros after the decimal point when its thickness is measured in mm. It is usually an aluminum foil with a thickness less than 0. 0075মিমি.

When expressed in English, thick foil is called “heavy duty aluminum foil”, একক শূন্য ফয়েলকে "মাঝারি গেজ ফয়েল" বলা হয়, এবং ডাবল জিরো ফয়েলকে "লাইট গেজ ফয়েল" বলা হয়.

বাইরের দেশে, aluminum foil with a thickness of ≤40μm is sometimes called light gauge foil, while aluminum foil with a thickness of >40μm is collectively called heavy duty (gauge) ফয়েল.

অ্যালুমিনিয়াম ফয়েল রোল অ্যালুমিনিয়াম ফয়েল এবং শীট অ্যালুমিনিয়াম ফয়েল এর আকার অনুযায়ী বিভক্ত করা যেতে পারে. Aluminum foil deep processing wool is mostly supplied in roll form, and sheet aluminum foil is only used in a few handicraft packaging situations.

Classification of aluminum foil by temper

অ্যালুমিনিয়াম ফয়েলকে হার্ড ফয়েলে ভাগ করা যায়, semi-hard foil and soft foil according to the temper.

• ① Hard foil: অ্যালুমিনিয়াম ফয়েল যা নরম করা হয়নি (annealed) রোলিং পরে, এবং degreasing ছাড়া পৃষ্ঠের অবশিষ্ট তেল আছে. অতএব, rigid foil must be degreased before printing, lamination, এবং লেপ. যদি এটি গঠন প্রক্রিয়াকরণের জন্য ব্যবহার করা হয়, এটি সরাসরি ব্যবহার করা যেতে পারে.
• ② Semi-hard foil: Aluminum foil whose hardness (বা শক্তি) is between hard foil and soft foil, usually used for forming processing.
• ③ Soft foil: fully annealed after rolling

The softened aluminum foil has a soft material and no residual oil on the surface. বর্তমানে, বেশিরভাগ অ্যাপ্লিকেশন ক্ষেত্র, যেমন প্যাকেজিং, composites, বৈদ্যুতিক উপকরণ, ইত্যাদি, use soft foils.

Classification of aluminum foil by surface smooth

Aluminum foil can be divided into one-sided smooth aluminum foil and two-sided smooth aluminum foil according to the surface condition.

• ① একক-পার্শ্বযুক্ত মসৃণ অ্যালুমিনিয়াম ফয়েল: ডাবল-ঘূর্ণিত অ্যালুমিনিয়াম ফয়েল. After being rolled, one side is bright and one side is darkened. Such aluminum foil is called single-sided smooth aluminum foil. The thickness of single-sided aluminum foil usually does not exceed 0.025mm.
• ② Single-sided bright aluminum foil: A single rolled aluminum foil, with both sides in contact with the roller. The two sides of the aluminum foil are divided into mirror double-sided aluminum foil and ordinary double-sided aluminum foil due to the different surface roughness of the roller. The thickness of double-sided aluminum foil is generally not less than 0.01mm.

Classification of aluminum foil by Surface technology

অ্যালুমিনিয়াম ফয়েলকে প্লেইন ফয়েলে ভাগ করা যায়, এমবসড ফয়েল, যৌগিক ফয়েল, প্রলিপ্ত ফয়েল, colored aluminum foil and printed aluminum foil according to the processing state.

• ① প্লেইন ফয়েল: Aluminum foil that has not undergone any other processing after rolling, also called light foil.
• ② Embossed foil: Aluminum foil with various patterns embossed on the surface.
• ③ যৌগিক ফয়েল: Composite aluminum foil formed by laminating aluminum foil with paper, প্লাস্টিক ফিল্ম, এবং পিচবোর্ড.
• ④ লেপা ফয়েল: Aluminum foil coated with various resins or paints on the surface.
• ⑤ Color-coated aluminum foil: Aluminum foil coated with a single color on the surface.
• ⑥ মুদ্রিত অ্যালুমিনিয়াম ফয়েল: Aluminum foil that forms various patterns, নিদর্শন, text or pictures on the surface by printing. It can be one color, পর্যন্ত 12 রং.

Aluminum foil can be classified by use

Ordinary aluminum foil: usually used in food packaging, preservation, cooking and other fields. This kind of aluminum foil is generally thin, soft and plastic.

Kitchen foil: Specifically designed for cooking and baking, it resists high temperatures and prevents food from sticking to the pan.

Medical Aluminum Foil: Used in the medical industry, for example to shield radiation during X-ray examinations.

Aluminum foil for electronics: It has high electrical and thermal conductivity and is used for packaging and shielding of electronic devices.

Insulating aluminum foil: With an insulating layer, used for the insulation of cables and wires.

Decorative aluminum foil: The surface can be coated, printed or treated and used in areas such as packaging, decoration and advertising.

Air conditioning foil: With special anti-corrosion and thermal conductivity properties, it is used for packaging of air conditioning ducts.

Pharmaceutical packaging foil: used for pharmaceutical packaging and usually needs to meet special standards for pharmaceutical packaging.

Automotive Aluminum Foil: Used in automotive parts such as automotive radiators.

Aluminum foil for construction: বিল্ডিং নিরোধক জন্য ব্যবহৃত, জলরোধী উপকরণ, ইত্যাদি.
