Product Description:

1.Structure of Electrolytic Tinplate for Foods and Chemical 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 for Foods and Chemical 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 do tin tins rust easily when they are opened?
The tinplate is of poor quality and the tin is not enough
Q:Who knows the process of tinplate production?
1. remove the oxide scales produced during hot rolling;2. the strip side edge trimming;3. coated with rolling oil, play a role in rust and lubrication;4. check and remove all kinds of surface defects which are harmful to the subsequent cold rolling process;
Q:How to open cans
A tin can be opened, the handle is separated, and the canned fruit can be clamped by the head, and the rotating knob and the tin can be opened. Remember, when you turn the knob, you can only rotate clockwise and turn counterclockwise clockwise.
Q:Can tinplate be shielded?
Two kinds of materials of tinplate and paktong in general: tinplate is cheaper, weldability is good, but easy to rust, and relatively soft, compared to a large shield narrow cover will have problems. Alpaka relatively high prices, the weldability is poor, but can provide performance through tin, relativelyhard. At present, the use of shielding in the mobile phone, these two materials are more, but taking into account the cost or priority of tinplate
Q:What about tin cans?
In the galvanic cells of the tin, iron is negative and oxidized because iron is more active than tinTherefore, in the coating damage after corrosion. Than tin tin
Q:How to distinguish galvanized plate and tin plate
From the outside, hot galvanized, electro galvanized tin plate surface is rough, thick tin layer of light and bright, thin tin layer, hot galvanized galvanized is not only the contest, Matt
Q:How can recycled tin cans be recycled?
Longhu white tin cans crusher is a company based on years of manufacturing experience carefully developed recovery special grinder, the crusher machine advantages in traditional variety, make full use of impact, shear, impact each other, grinding theory carefully developed.
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 kind of material is tinplate?
Tin plate is tin plated steel, that is iron.
Q:Cookie with tinplate packaging has what advantage
Tinplate has obvious superiority compared with other packaging materials.
