Product Description:

1.Electrolytic Tinplate (ETP) Coil and Sheets for Chemical Packaging 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 (ETP) Coil and Sheets for Chemical Packaging


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:Tin plated tin plated?
Because of the punching after the incision site no tin layer, while most parts of surface layer of tin, the pretreatment process of adverse, removing tin layer will damage the substrate without removing the tin layer if not plating parts difficult to achieve uniform effect
Q:How can tinplate be identified?
Mainly to see whether the surface is smooth, whether there are holes in the surface, there are no wave edges, scratches, tin is enough, the size is not in tolerance Wai?. Wait a lot. Specific problems are analyzed in detail, and there are many aspects of assessing quality problems, and so 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: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.
Q:Should vacuum filling be required for tinplate meat filling?
Mainly depends on your production process needs
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:How to prevent the corrosion of tinplate wall hydrogen sulfide blackening, expansion
Cathodic protectionProtective screen corrosion protection. The principle of protecting the screen is to make the metal of the anode corrode and protect the cathode metal material from corrosion. A metal or alloy (shielding material) connected to the surface of a metal tank and pipeline to be protected shall be protected from corrosion due to the low potential in the primary cell and corrosion of the screen material used as an anode. This method is applicable to the preservation of oil storage tanks, oil tankers and underground oil pipelines. Screen materials are commonly used, including series, aluminum, town and alloy.Cathodic protection of impressed current. Impressed current cathodic protection method is to protect the metal pipelines and oil storage tanks and electrical excavation of the negative link, as a cathode and protected; the power supply of the positive steel scrap corrosion. The method is applicable to underground oil storage tanks, underground pipelines and terminals, pipelines and tankers directly connected with the sea. Generally used anode materials are scrap iron and steel, graphite, high silicon iron, magnetic iron oxide, etc., these materials are consumed, can be replaced at any time.
Q:Tinplate which applies to product packaging?
Barrier: tinplate cans have excellent 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. 3. mature technology and high production efficiency: the production of tinplate has a long history, mature technology is a set of production equipment with matching, high production efficiency, can meet a variety of product packaging needs.
Q:The composition of tinplate?
Tinplate is a tin covered with tin, it is not easy to rust, also known as tin iron. This kind of galvanized steel in a long time Chinese called "tin", some people think that the tin plate cans was made from the Guangdong province of Macao (English Macao for tinplate imports, readable) so called "tin".
Q:What are the differences in the corrosion behavior of two ferrous iron products?
Tinplate is a tin covered with tin, it is not easy to rust, also known as tin iron. This kind of galvanized steel in a long time Chinese called "tin", some people think that the tin plate cans was made from the Guangdong province of Macao (English Macao readable if imported, tin) so called "tin".
