1.Structure of Electrolytic Tinplate Sheets for Foods Can Packaging Description

 

Electrolytic Tin Plate Coils and Sheets for Foods Metal Packaging,  is one thin steel sheet with a coating of tin applied by electrolytic deposition. Tinplate made by this process is essentially a sandwich in which the central core is strip steel. This core is cleaned in a pickling solution and then fed through tanks containing electrolyte, where tin is deposited on both sides. As the strip passes between high-frequency electric induction coils, it is heated so that the tin coating melts and flows to form a lustrous coat.

 

2.Main Features of the Electrolytic Tinplate Sheets for Foods Can Packaging

 

Appearance – Electrolytic Tin Plate is characterized by its beautiful metallic luster. Products with various kinds of surface roughness are produced by selecting the surface finish of the substrate steel sheet.

Paintability and printability – Electrolytic Tin Plates have excellent paintability and printability. Printing is beautifully finished using various lacquers and inks.

Formability and strength – Electrolytic Tin Plates have got very good formability and strength. By selecting a proper temper grade, appropriate formability is obtained for different applications as well as the required strength after forming.

Corrosion resistance – Tinplate has got good corrosion resistance. By selecting a proper coating weight, appropriate corrosion resistance is obtained against container contents. Coated items should meet 24 hour 5 % salt spray requirement.

Solderability and weldability – Electrolytic Tin Plates can be joined both by soldering or welding. These properties of tinplate are used for making various types of cans.

Hygienic – Tin coating provides good and non toxic barrier properties to protect food products from impurities, bacteria, moisture, light and odours.

Safe – Tinplate being low weight and high strength makes food cans easy to ship and transport.

Eco friendly – Tinplate offers 100 % recyclability.

Tin is not good for low temperature applications since it changes structure and loses adhesion when exposed to temperatures below – 40 deg C.

Q:Why tin tin plating?
Tin is the famous "hardware" - one of gold, silver, copper, iron and tin. As early as in ancient times, people discovered and used tin. A number of ancient tombs in China, they often find some tin pot, like tin tin candlestick. According to research, China's Zhou Dynasty, the use of tin has been very common. In the ancient tombs of Egypt, tin articles were also found.
Q:How to quickly distinguish tinplate and ordinary substrate iron?
Tinplate is tin coil, measurement of tin content?. The base plate is a plain hard rolled coil, which is relatively hard without annealing.
Q:What are the causes of tinplate rusting and how to prevent them?
The tin surface of the iron sheet is injured and exposed during the machining process to promote corrosion.Prevention: 1, not coated iron sheet, coated with oil after plating thickening. Effectively prevent water invasion and reduce damage to the process.2 can be painted on the iron sheet of appropriate paint, blocking the impact of corrosive substances.
Q:Is it necessary for the two cold rolling in the process of tinplate production, such as tempering and cold rolling (also called flatness)?
This is not the standard terms, generally refers to the 2 cold rolling coil after cold rolled hardness increased after heat treatment after recrystallization to obtain greater reduction.
Q:How do you solve the water stains on the tinplate?
Feel the basin soil, if the surface is still felt humidity, can pinch the water, then it is necessary to take out the whole plant, breathable, basin soil slightly dry and then put back, half Yin conservation.
Q:How can the section of the tinplate be maintained without rust?
The cross section of the tinplate is free of rust. Both sides have plating, the cross section can use lubricating oil
Q:Advantages and disadvantages of tinplate packaging
Characteristics and advantages of the 1. materials can tinplate opaque sealed 3. tin 2. good reduction of 4. provides a source of effective iron 5. Recyclable, reuse. In compliance with international environmental requirements, in line with the future trend of the 6. products is strong, good protection, no deformation, shock resistance, fire resistance, resistance to high temperature and high pressure
Q:Tin can bake oven electrical electromagnetic induction principle
If it is not sealed, it is said to be heated and then changed after being heated.
Q:Can tinplate be shielded?
For tinplate shielding, it is a kind of shielding material, at present 3 applications more cheap, processing is good, but the finished long-term placement of rust on the fracture surface, thus affecting the weldability, which is its only drawback. If it is placed in a short time, it will not affect weldability. Electroplating is not the best way to solve the problem. My supplier is coated with an anti rust paint on the fracture surface, and then ultrasonic cleaning is done before going on line. But I mostly use "ocean shield frame copper to make," a little expensive, but the performance is very good ^_^
Q:The composition of tinplate?
The name "tinplate" is not exact. Therefore, in 1973, when the Chinese tin plate meeting was called "tinplate", the official document no longer used the name "tinplate".
