About tinplate

Release date:2017-12-18 Author: Click:


 The origin of tinplate

  Tinplate earlier said the foreign iron, the official name should be tinplate. Because the first batch of China's foreign railways was imported from Macau in the middle of the Qing Dynasty, Macau was transliterated at that time. Therefore, the Chinese generally refer to it as (tinplate).

What is tinplate?

  Tinplate is commonly known as tinplate plating, the English abbreviation for SPTE, refers to both sides of pure tin coated cold rolled low carbon steel sheet or strip, also known as tinplate. Tin mainly plays a role of preventing corrosion and rusting. It combines the strength and formability of steel with the corrosion resistance, solderability and aesthetic appearance of the steel in a material that is corrosion-resistant, non-toxic, and high in strength , Good ductility.

The characteristics of tinplate

  Tinplate is widely used in packaging, it has its advantages:

(1) It has opacity, the light will cause the deterioration of food in addition to the reaction, but also cause changes in protein and amino acids, tinplate cans of opaque vitamin C preservation rate is the highest.

(2) good sealing quality

(3) The reduction of tin reduces the chance of food being oxidized

(4) to provide a source of available iron, due to the electrochemical effect of metal, canned food storage will be a small amount of iron dissolved in bivalent iron in the form of sealed canned food, it is easy to be absorbed.

  Because of these attributes, tin cans provide an airtight system that, in addition to heat, completely isolates the environment from containing food and beverages to prevent food from deteriorating by light, oxygen, moisture, or by the passage of aroma Faded or smells smelling through the smell of the environment, the stability of food storage better than other packaging materials, the highest preservation rate of vitamin C, nutrient retention is also the best.

  The above is a little bit of tinplate knowledge, in fact, the story took place in our lives, we live and work in full of knowledge, as long as good at learning, boring things will become very interesting, your spirit will change Very rich.
