1.Structure of Electrolytic Tin Plate  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 Tin Plate Coils and Sheets for Chemical 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.

Q:What are the causes of tinplate rusting and how to prevent them?
Invasion of water. The water is on the iron sheet to form a galvanic cell. This should keep the environment dry. Besides, the temperature difference between the iron sheet and the environment should not be too great to avoid the moisture in the air falling out on the sheet iron.
Q:What is the use of tinplate printing tin, storage of food safety
Electrophoresis on a layer of special coating with food packaging, the packaging is extremely tight, in order to packaging material appearance, appearance are printed with various patterns, because it is the coating of food grade materials, so the food packaging is safe in the warranty period.
Q:What do tinplate do?
If is a tin factory, then electroplating factory, the process is open book, roll up, cold rolled plate by welding, looper, alkali washing, acid pickling, tin plating, soft melting, chemical treatment passivation, oiling and rewinding.
Q:Cookie with tinplate packaging has what advantage
Tinplate has obvious superiority compared with other packaging materials.
Q:Why tinned fruit cans, some snow wall, and some inner wall does not appear?
Tin cans inside must use the high Xiliang (11.2 - 15.1), the inner wall of the conventional oxidation after a snowflake, which belongs to the benign chemical reaction, enhance the taste.
Q:0.25mm which melting point is low in tin plate and tin plate?
Tin plated steel sheet and strip, also known as tinplate, the steel plate (belt) surface tin plated, has good corrosion resistance, non-toxic, can be used as packaging material cans, inside and outside the cable sheath, telecommunications instrument parts, flashlight and other hardware.
Q:A tin rust problem for help
Once the outer rust rust, if the area is not large, can use sandpaper to rub the rust, and then wipe clean towel can surface, then coated with a layer of antirust oil; if the outer rust area of about 1/2, we must take into account whether the corrosion to the inner wall, has affected the quality of the contents. If rust occurs on the inside, you need to remove all the rework, tank canning, liquid injection, degassing, sealing and sterilization, cooling, after 2 times of high temperature sterilization of canned products, generally need to downgrade, or if some products in the two sterilization will appear after taste and color changes, you need to direct rejection.
Q:Why tin printing after a layer of light oil
The performance of tin light oil to complete all printing tin printing, to cover a layer of light oil, to increase the printing surface gloss and anti scratch performance, but also increase a certain hardness, the printing surface coating has certain flexibility and corrosion resistance.
Q:Can you tell me how to deal with the recycling of tinplate?
General tinplate packaging waste, as long as the rust is not serious, can be converted into hardware products, to achieve the best use of materials. The consumption of tinplate in our country is relatively large (600 thousand tons / year), and 125 tons of tin packing waste can be recovered 1 tons of tin.
Q:What is tin plate
Tinplate is made of iron tin alloy and tin is plated. Mainly used in food packaging, tin cans production, because the tin steel strength and formability and corrosion resistance of tin soldering, and beautiful appearance with a material, corrosion resistant, non-toxic, high strength and good ductility properties.
