Product Description:

1.Structure of Tin Free Steel of Prime High Quality for Metal Containers Description


Also known as chromed steel, tin-free steel (TFS) is obtained by coating the metal base (low-carbon steel) with an ultra-thin layer of metallic chrome and then with a chromium oxide layer.


2.Main Features of the Tin Free Steel of Prime High Quality for Metal Containers


Chromium coated

Corrosion Resistant

Easier to recycle.

Sulphur Blackening Resistance: TFS has sulphur resistance properties, which can be used for canning protein- rich food such as fish.

Filiform Rust Resistance: Filiform is superficial corrosion of the base metal. TFS has a superior base metal which makes it corrosion resistance.

Coating: The coating in TFS is not amphoteric (having the characteristic of an acid and a base, is a compound that can react as either an acid or a base). This means that detergents and dispersion colors can be packed easily.

Paint Adhesion : TFS possesses better paint adhesion properties, thus making it ideal for DRD cans and adhesive bonded cans.

Weldability: TFS can be welded when metallic coating layers are removed by edge grinding.

TFS should be Lacquered / Coated to prevent rust in humid condition.

Internal Coating / Lacquering can be avoided in the case of TFS used to store motor oil or cooking oil.

Q:How many kinds of tinplate are there? What is the code number?
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 when the manufacture cans from Macao (English Macao for tinplate imports, readable) so called "tin". 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: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:How do you clean the dust and trace oil on tin containers?
Solvent cleaning: This is the traditional way, from the middle of the Qing Dynasty period have been used, it is with a cleaning agent such as solvent, steam coal, white oil (to waterlogging, water purifier, hydrocarbon and so on).
Q:Why tinned fruit cans, some snow wall, and some inner wall does not appear?
Tin cans inside must use the high Xiliang (11.2 - 15.1), the inner wall of the conventional oxidation after a snowflake, which belongs to the benign chemical reaction, enhance the taste.
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:Can tinplate be used as a water tower? Is hot water durable?
Tinplate is commonly known as tin plated thin steel plate. It is a cold-rolled low carbon steel sheet or strip coated with pure tin on both sides. Tin plays a major role in preventing corrosion and rusting.
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:Is it necessary for the two cold rolling in the process of tinplate production, such as tempering and cold rolling (also called flatness)?
The leveling process is only to change the yield platform or to improve the plate shape. Under normal pressure is very small, can not be considered cold rolled in the true sense.
Q:Can you tell me how to deal with the recycling of tinplate?
General tinplate packaging waste, as long as the rust is not serious, can be converted into hardware products, to achieve the best use of materials. The consumption of tinplate in our country is relatively large (600 thousand tons / year), and 125 tons of tin packing waste can be recovered 1 tons of tin.
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.
