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:Why do tin tins rust easily when they are opened?
Tin iron loses electrons and gets an electron redox reaction to accelerate the corrosion process
Q:How to test the tightness of tin metal cans?
The empty tank which has been cleaned can be dried by 35, and the pressure or pressure leak test shall be carried out according to the equipment condition of each unit. B.1 pressure leak test, the empty tank will be carefully injected into the water until eight or nine into full, the rubber ring will be placed in the appropriate plexiglass plate at the opening side of the roll, so that it can be sealed. Start the vacuum pump, turn off the bleeder valve, hold down the cover by hand, control the pumping, and make the vacuum gauge rise from 0Pa to 6.8X10 PA (510mmHg) for more than 1min, and keep the vacuum above 1min.
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 is the difference between food grade tinplate and ordinary chemical tinplate? What is the difference between MR material and SPCC?
No general food grade and ordinary chemical tinplate tinplate. There are some major is not mature in domestic tin (MR, L, D) the production of tinned steel substrate outside, technology is not mature, not environmental protection, so there is a risk for food cans, can only be used for chemical tank.
Q:Tin plated tin plated?
Galvanized steel / strip is easy to retreat, the damage to the substrate is very small, but also to ensure the production of rust in the stamping process, you can use.
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:What kind of material is tinplate?
This past China 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:Should vacuum filling be required for tinplate meat filling?
Mainly depends on your production process needs
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.
Q:What details should I pay attention to when purchasing tinplate packing boxes?
Long engaged in procurement can know, when custom cans tends to care about is the first mold, mold it all if there is to say, if there is no mold that must face mold, mold cost is between the price of tin supplier are not much different from what. The key is really quantity.
