1.Structure of Electrolytic Tinplate Coils and Sheets for Tin Cans Making 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 Coils and Sheets for Tin Cans Making

 

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:Does the tinplate have a tensile rate? Thank you heroes!
Where Sn is the tin plating, tin tin iron is also called the iron horse known as tin plating English, abbreviated as SPTE, is a commercial pure tin plating of cold rolled low carbon steel sheet or strip. Tin plays a major role in preventing corrosion and rusting. 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 do you solve the water stains on the tinplate?
Feel the basin soil, if the surface is still felt humidity, can pinch the water, then it is necessary to take out the whole plant, breathable, basin soil slightly dry and then put back, half Yin conservation.
Q:How to test the tightness of tin metal cans?
Pressure leakage test with a rubber plug when empty hole plugged, start the air compressor, slowly open the valve, the pressure in the tank is increased gradually, while the empty tank is immersed in the water tank, careful observation with outer bottom cover curling and welding seam has no air bubbles, until the pressure rose to 0.7jg/cm and 2min. All the same parts of continuous bubbles, should be judged as leakage, leakage of the recording time and pressure, and mark in the leak site on.
Q:What is the process of two cold rolling of tinplate?
Tinplate is commonly known as tin plated steel sheet. The English abbreviation is SPTE. It is a cold-rolled low carbon steel sheet or strip coated with commercially pure tin on both sides.
Q:Can you tell me how to deal with the recycling of tinplate?
The tin is magnetic, is easy to recycle scrap. Second, waste tin as scrap iron and steel melted, make steel containing a small amount of tin (less than 0.1%), to improve the performance of cast iron.
Q:Advantages and disadvantages of tinplate packaging
Because of these properties, so can provide a besides the heat, completely isolated from the closed system of environmental factors, avoid color food because of light, oxygen, moisture and deterioration, nor because of aroma through and become weak or affected by environmental pollution through the smell and taste, stability is better than that of other packaging materials of food storage. Vitamin C save the highest rate, nutrient retention is the best. International environmental management standards will be implemented soon based on ISO-14000, has the advantages of low pollution, tin recycling, resource characteristics, in the future packaging applications, will have a broader space for development.
Q:Can tinplate be shielded?
For tinplate shielding, it is a kind of shielding material, at present 3 applications more cheap, processing is good, but the finished long-term placement of rust on the fracture surface, thus affecting the weldability, which is its only drawback. If it is placed in a short time, it will not affect weldability. Electroplating is not the best way to solve the problem. My supplier is coated with an anti rust paint on the fracture surface, and then ultrasonic cleaning is done before going on line. But I mostly use "ocean shield frame copper to make," a little expensive, but the performance is very good ^_^
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 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:Tin and tinSince the back skin as long as tinplate will rust, so why not replace tin?
Oftinned is actually, tinplate, commonly used in food and beverage packaging, have good anti-corrosion effect, and no harm to human body. We used a lot of tinplate cans, is done. The tinplate back skin, is actually the plate above the tin, is physical effect eroded, so the steel will rust.
