Product Description:

1.Structure of Electrolytic Tinplate (ETP) 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 (ETP)

 

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 tinned fruit cans, some snow wall, and some inner wall does not appear?
The same is canned fruit, tin cans taste more than glass bottles, why is it better? Because the storage process is completely isolated from the sun, so that it can retain the original flavor of canned fruit.
Q:How can tinplate be rustproof? Products must not be oil
RP014C-23A thin layer quick drying antirust oil is made up of film forming agent, oil soluble corrosion inhibitor and refined petroleum solvent. It is a kind of volatile long-term antirust oil.
Q:You can do is tin iron electromagnet
This kind of galvanized steel in a long time Chinese called "tin", some people think that the tin plate cans was made from the Guangdong province of Macao (English Macao for tinplate imports, readable) so called "tin".
Q:Cookies with tinplate packaging has what advantage?
Mature technology and high production efficiency: the production of tinplate has a long history, mature technology is a set of production equipment with matching, high production efficiency, can meet a variety of product packaging needs.
Q:What are the advantages of tin packaging?
1. good mechanical properties: tinplate cans relative to other containers, such as plastic, glass, paper containers and strength, and good rigidity, it is not easy to break. It is not only used for small sale packing, but also the main container for large transportation package.2.: excellent barrier tin barrier properties than any other materials are excellent, gas barrier properties, moisture resistance, shading and aroma were good, and the sealing is reliable, reliable protection products.
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:Tin can weldingHow can the side of the column of the pop top be welded or pressed?,
The iron material thickness uniformity in the welding process, welding voltage and high requirement of control, the slightest mistake will cause breakdown or welding point is easy to fall off. As for the production of specific steps, personal suggestions to the scene you see, because the whole process is relatively simple, and when it comes to the production process and principle very boring, tedious. So, if you just want a rough understanding, there is no need for this.
Q:How to prevent the corrosion of tinplate wall hydrogen sulfide blackening, expansion
Oil pipelines and oil storage containers buried in the ground are exposed to the water, salt, alkali and acid substances directly in the soil, and they should be coated with antirust paint on the outside surface, and then sprayed with asphalt protection layer.
Q:What are the differences in the corrosion behavior of two ferrous iron products?
There are other statements, such as China used this lamp tin plate made of kerosene, shaped like a horse, so called "tin".
Q:Tin and tinSince the back skin as long as tinplate will rust, so why not replace tin?
Tin, also called galvanized sheet steel, atmospheric corrosion resistance ability is strong, not afraid of the rain and wind, used for building materials, general exposure in the air. Such as color plate, color steel. Because it is hard, so it is not easy to physical erosion. If the galvanized layer off, the same will rust.Can not be used. Instead of using tin tin galvanizing vessel, it is easy to cause zinc poisoning. Zinc soluble in acid, acid resistance is poor, so the tin can not be used for beverage packaging, such as carbonated drinks and fruit juice. In addition some foods, such as aquatic products, or products such as packaging, the requirements are higher, need to use advanced professional tinplate.
