That's how tinplate came about
2022-04-24 11:02:35

The predecessor of tinplate cans - tinplate is often referred to as electroplated tin sheet steel. The English abbreviation is SPTE, which refers to cold-rolled low-carbon sheet steel or steel strip plated with commercial pure tin on both sides. It has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility.


The origin of the name of tinplate: The first argument is that it is called tinplate because the canned tinplate is imported from Macau (the English name can be read as tinplate). Another way of saying it is that in early China, the lamp cap of kerosene lamps made of tinned steel plates was shaped like a tinplate, so it was called tinplate.


Due to the inaccuracy of the name tinplate, in 1973 the China Tinplate Conference was renamed Tinplate, and the name tinplate was no longer used in official documents.


Tinplate is like a woman.


First, the application of tinplate:


Tinplate packaging containers are very popular among customers, such as tinplate cans, which are widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrumentation packaging, industrial product packaging, etc.


Second, the basic principles of tinplate selection:


T-1 49+/-3. Especially suitable for deep processing tanks that require softness.


T-2 53+/-3. Suitable for further processing tanks that require general softness.


T-2.5 55+/-3. Suitable for cans or can lids that require good flexibility.


T-3 57+/-3. Suitable for tanks requiring high hardness. Covers, etc.


T-3.5 59+/-3. Suitable for tanks that generally require good toughness.


T-4 61+/-3. Suitable for tanks that generally require greater toughness.


T-5 65+/-3. Suitable for lids of large tanks or internal pressure vessels, with good bending resistance.


DR-873. It is suitable for beer, carbonated beverage cans or lids that require a certain stiffness and strength.


DR-976. It is suitable for beer, carbonated beverage cans or lids, Dr cans, etc. that require a certain stiffness and strength.


DR-9M 77. Suitable for beer. Carbonated beverage can lids, etc.


DR-10 80. It is suitable for high-grade bottle caps that require a certain rigidity and strength.


3. Common defects of tinplate:


1. Causes and improvement measures


1 indentation


There is a foreign object on the drum. Or replace the grinding roller.


2 Roller Smudges


There is a foreign object on the drum. Or replace the grinding roller.


3 Insufficient electroplating. Insufficient oiling. Black ash.


Equipment abnormal shutdown processing


4 Scratches. Wear marks


Choose the packing method when shipping, strengthening/slitting.


5 Roller Scratches


Roll speed does not match line speed. Adjust the roller diameter to match the speed.
