Under what conditions tinplate box will rust?
Tinplate tinplate is commonly known as tinned steel plate. It is abbreviated as SPTE in English. It refers to cold-rolled low-carbon steel plate or strip coated with commercial pure tin on both sides. Tin mainly prevents corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and aesthetic appearance of tin in a material that is resistant to corrosion, non-toxicity, high strength, and good ductility. A tinplate box is a tin plate coated with a tin layer on the surface. It is not easy to rust, and it is also called tinplate. This type of coated steel plate has long been known as a “tinplate box” in China. Some people think that because the tin plate used for canning was imported from Macao, Guangdong Province (English name, Macao can read Ruomakou), it is called a tinplate box. ".
There are also other sayings. For example, in China, the head of a kerosene lamp was made of such a tin plate. It was shaped like a horse's mouth, so it was called a tin box. The name “tinplate box” is inaccurate. Therefore, in the 1973 tinplate meeting in China, it was already known as tinplate. Official documents no longer use the name “tinplate box”. Tinplate box One of the alloys that we often say now. The chemical properties of the alloy are very good, combining the advantages of two or more metals. Tin is chemically stable and is not susceptible to corrosion. The chemical properties of iron are not very stable and easily oxidized, but the hardness of iron is large and the moldability is good. Tin is often plated on the outside of the iron sheet to prevent corrosion of the sheet metal. This kind of tin that wears tin "clothes" is known as the "tin box". One ton of tin can cover more than 7,000 square meters of iron. Therefore, tinplate boxes are common and very cheap. The largest "consumer" of tinplates is the canning industry. If attention is paid to protection, tinplate boxes can be kept stainless for more than a decade. However, once the “clothes” of tin were accidentally knocked over, the iron pieces were quickly rusted (electrochemical corrosion), and soon the entire tinplate box was covered with red-brown rust. Therefore, when using a tinplate box, care should be taken not to damage the tin layer and to make it moist and hot. Before the liberation, due to the imperialist aggression, China’s tin box had to rely on foreign imports. The name Tinplate Box was originally named because it was imported from the horse-mouth of Ali, Tibet (the United Kingdom was imported from Makou through India).
Tinplate box is also known as tin plate, tin plate, and iron battery. Under the action of water, oxygen and carbon dioxide, galvanic reaction occurs. Because iron is more metallic than tin, iron is corroded at the cathode, and iron is protected at the expense of tin. Accelerate the corrosion of iron.
There is no particularly good way to prevent the tinplate from being corroded. You can brush oil or anti-rust paint on the outside of the tinplate box, but you must not break the skin of the tinplate box.
Tinplate Embroidery Removal Method:
Rust removal (line treatment) → water wash → flash plating copper replacement → water wash → mechanical galvanizing deposition transition layer → mechanical galvanizing deposition → water polishing → part pouring separation → hot water washing (or chrome passivation on the surface of the required parts, Dipping related protective layer) → spin drying and drying → inspection and acceptance
