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 quickly open the bottle?
Put the tins of canned fruits soaked in hot water for 3-5 minutes, so that the tank gas temperature rises, the pressure is increased, which is the principle of expansion and contraction. Turn the canned fruit bottle upside down for a while. When the liquid in it breaks down the vacuum inside and outside, tap it in the bottom with your palm and pull it gently. It's easy to pull apart.
Q:How big is the difference between tinplate and stainless steel 316L?
It will be the 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.
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's the head iron?
SPTE, which is commonly known as tin, tin plate, thickness of 0.15-0.3mm, width, generally between 300-900mm.
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.
Q:What's the difference between iron, aluminium, stainless steel, galvanized iron and tin?
Aluminum is a kind of material. It is not easy to be oxidized when it meets water. The price is moderateStainless steel is another kind of material. It is not easy to be oxidized when it meets water. The price is high
Q:How can the section of the tinplate be maintained without rust?
Heat the pot, wipe with fat pork and pig skin, over five minutes, and never rust again
Q:What are the differences in the corrosion behavior of two ferrous iron products?
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".
Q:You can do is tin iron electromagnet
There are other statements, such as China used this lamp tin plate made of kerosene, shaped like a horse, so called "tin". 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".
Q:Why tin printing after a layer of light oil
Bright oil is common in epoxy resin, alkyd resin, acrylic resin, acrylic amino, etc., the composition is different, the performance is also different, and the use is not the same. Usually according to the process whether there is a deep stamping deformation, welding local high temperature heating and the need for high pressure cooking and so on, choose different types of varnish.In order to increase production efficiency and save energy, in general, the last printing process is combined with the glazing process.In addition to the roller coating can be used, but also can be printed light ink method, both gloss is not much difference, but the processing performance is better than roller coating.
