1.Structure of Electrolytic Tinplate in Coils 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 in Coils 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:Tinplate also known as what? What is the density of it?
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:Tinned iron and iron matte tin in difference
Tin tin in tin and iron is ordinary, the price is cheaper than the frosted iron, no sand surface, at the grassroots level printed on a white layer after printing all kinds of exquisite patterns, but also can do all kinds of gold silver transparent iron printing, in the light can return the light, give a person a kind of dazzling feeling also, high-grade, affordable prices, so the tinned iron printing packing made by wide customers.
Q:The difference between a matte tin plate and a bright tin plate
Rough tinplate:After a slight rough treatment was to remove the original board plating processing gloss after use, through the soft melting process, which has a unique metallic luster, is a kind of printing, cans and other processing to generate abrasion and easy to use tinplate.
Q:Cookies with tinplate packaging has what advantage?
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.
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 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:Who knows the process of tinplate production?
Cold rolling: the hot rolled strip passes through the pickling process and enters the cold rolling process. The strip is plastically deformed during the work roll, and the thickness is about 2mm.2mm from about 0. In cold rolling, in order to reduce the friction between the strip and the work roll and take away a large amount of heat produced by the plastic deformation, the cold rolling lubricant and coolant should be sprayed onto the strip. A reversible mill with single stand is adopted. In order to keep the shape of the roller effectively, the temperature control of the cooling liquid is more important. Range of production: 0.14mm-0.5mm.Slitting: the required width of slitting material after cold rolling. Range of production: 265mm-835mmSkim: in the cold rolling process in rolling oil cooling after tin plate surface adhesion of oil and other foreign matter, such as do not wash directly by annealing the oil incomplete combustion of carbonaceous residue will stain in the strip, for the production of tinplate can meet the quality requirements. Therefore, the tin plate must be cleaned by electrolysis before removing the grease. The common method of cleaning tin plate is to degrease and degrease the degreasing liquid.
Q:What is the difference between food grade tinplate and ordinary chemical tinplate? What is the difference between MR material and SPCC?
Tinned food grade and non food grade. The main brands are MR and SPCC. because the meat food will be wall mounted in contact with food tin coated with two layers of yellow food, the food is yellow anti solvent, anti general acid-base, thus ensuring the safety of food packaging containing iron. The food there is no absolute security argument, now the technology has been fully capable of ensuring the safety of food containing.MR's impurity is a little more than SPCC, and the price is a little high. It's OK to use SPCC to spread two layers of food on the outside
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:Cookie with tinplate packaging has what advantage
Tinplate has obvious superiority compared with other packaging materials.
