Product Description:

Electrolytic Tinplate undoubtedly enjoys the pride of place as a packaging medium especially for food. It owes its unique position to its "nine layer sandwich structure", each of which contributes to its eminence as a packing material. The steel base provides the necessary strength and formability for can fabrication. The tin-iron alloy layer provides the bond between the steel and free tin layer. The free tin layer is not only responsible for the attractive bright finish and ease of solderability but is also non-toxic- a factor of vital importance in food packaging!


Electrolytic TinPlate: Composition


E.T.P. consists of five layers each of which performs a different role:

1.
Steel Base: Provides stiffness to the material due to its thickness and mechanical strength. Its chemical composition imparts special properties to resist corrosion.

2.
Iron-Tin Alloy: This is made up by the inter-metallic compound Fe-Sn2. Due to its electrochemical characteristics, it acts as a barrier against corrosion. For effective action, its continuity is more important than its quantity.

3.
Metallic Tin: Tin has many advantages which have turned it into the most important element to protect steel used for cans; in many foods, it acts as a simple barrier against corrosion, improves weldability, it is an excellent base for lithographic printing and for applying lacquers. In tin-robbing foods, it acts as a sacrificial element.

4.
Passivation Film: According to its nature, it makes it possible to improve the E.T.P.’s resistance to sulphiding, oxidation and rust. It is also a conditioner to improve the adherence of varnishes, inks, lacquers etc.

5.
Oil Film: Protects the sheet from the humidity in the environment and makes easy to handle. It is applied using an electrostatic oiler on both sides of the sheet.

Q:How to test the tightness of tin metal cans?
A careful observation of empty tank tank bottom edge and welding seam has no air bubbles, where the same parts of continuous bubbles, should be judged as leakage, leakage of the recording time and vacuum degree, and make a mark in the leak site.
Q:Both tinplate and stainless steel have corrosion protection
Tinplate is common steel tin plating, tin coating is broken, later, because the tin is more corrosion resistant than iron, so iron will sooner corrosion. Mainly used for tins.
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: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:0.25mm which melting point is low in tin plate and tin plate?
Zinc plating on the surface of thin steel plates and steel strips by continuous hot dip plating prevents corrosion of the surface of thin steel plates and steel strips. Galvanized steel sheet and steel strip are widely used in machinery, light industry, construction, transportation, chemical industry, post and telecommunications and other industries
Q:Soup with tin cans loaded also need high temperature sterilization?
At present, there are DN400x500, DN600x1000, DN800*1000, DN900*1000 and DN900x1500 in the market, and the small sterilization pot with boilers is heated by steam. If not, heating by electricity can also be done. The phone won't be left. If you need any service from the manufacturer, you can call me from Hi. The key is not to sell, eliminating confusion is the key.
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: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:Tin cans and tin cans, which is good?
Tin is tin plate, of course tin tin is tin pot. Another name is tin plate. For example, you ask tomatoes and tomatoes which taste good, as the brothers in Pohang say, the same thing is different.
Q:What is the difference between food grade tinplate and ordinary chemical tinplate? What is the difference between MR material and SPCC?
The chemical composition of MR material is more strict than that of SPCC material, and the impurities are fewCanned fish must be made of good quality MR material, which reduces the risk of canning
