1.Structure of Electrolytic Tinplate in Coils for Foods and Chemical Cans Packing 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 in Coils for Foods and Chemical Cans Packing

 

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: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:What is tin plate?
Tinplate is a tin covered with tin, it is not easy to rust, also known as tin iron. Tinplate was most premature in Bohemia (now Czech and Slovakia). The land has been rich in metal since ancient times, advanced in technology, and know how to use water power in the manufacture of machinery, from fourteenth Century onwards began to produce tinplate. For a long time, it has been the main source of tinplate in the world. Tin was mainly used for making tableware and drinking utensils.
Q:What are the causes of tinplate rusting and how to prevent them?
The tin surface of the iron sheet is injured and exposed during the machining process to promote corrosion.Prevention: 1, not coated iron sheet, coated with oil after plating thickening. Effectively prevent water invasion and reduce damage to the process.2 can be painted on the iron sheet of appropriate paint, blocking the impact of corrosive substances.
Q:What is the use of tinplate printing tin, storage of food safety
Electrophoresis on a layer of special coating with food packaging, the packaging is extremely tight, in order to packaging material appearance, appearance are printed with various patterns, because it is the coating of food grade materials, so the food packaging is safe in the warranty period.
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:Cookie with tinplate packaging has what advantage
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 than any other...
Q:Tin, tin plated iron. Why can't we get white wine?
Should be caused by the unqualified corrosion resistance of the tinplate. The reasons are as follows:Tin plating on the surface of the tinplate has played a certain role in corrosion protection, tin surface will be six chromium passivation, further improve the corrosion resistance. However, the liquor contains a lot of water, and if the long-term contact with the iron (without coating tin), the surface of the tin layer will be corrosion, and then corrosion to iron.
Q:Can tinplate be shielded?
Two kinds of materials of tinplate and paktong in general: tinplate is cheaper, weldability is good, but easy to rust, and relatively soft, compared to a large shield narrow cover will have problems. Alpaka relatively high prices, the weldability is poor, but can provide performance through tin, relativelyhard. At present, the use of shielding in the mobile phone, these two materials are more, but taking into account the cost or priority of tinplate
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: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
