Aerosol Tinplate Can
As is known, light can cause and accelerate oil oxidation, which reduces nutrition value of oil by destroying its vitamin A and D, and even more seriously, by generating harmful substances. And, oxygen in the air can also lead to food oil oxidation, resulting in decreased protein biomass and damaged vitamins. To avoid this, we have developed tinplate that has high opacity and excellent airtight seal, and can provide better protection for the contained oil, food, beverage, and so on. Hence, the oil tin can is ideal for packing lipids.
To provide the highest quality oil tinplate can, we implement rigid inspection on the whole process from material procurement to the final product delivery. In addition to strict monitoring on working procedures such as acid washing, reciprocal rolling, and degreasing, etc., our specialized personnel check our products through mechanical property tester and coating tester to ensure superior performance of our oil tin can. As a result, our oil tin can features strong corrosion resistance, high formability and easy welding, and you can thus feel secure in choosing our products.
Tinned substrate steel is mostly low carbon mild steel, the carbon content is generally 0.03% ~ 0.13%. Before the development of continuous casting technology, mostly casting boiling steel and gland steel were used. Although these steels have good surface quality and can be rolled to tin-coated substrates, they cannot be used as tin-coated substrates with high forming properties due to the existence of component segregation during the casting and solidification of the ingot and the great difference in mechanical properties in the rolling direction and width direction. Since the rapid development of continuous casting technology in the 1970s, the continuous casting slab is suitable for improving the shape quality and forming stability of the tin plate because of its uniform chemical composition, small segregation and small fluctuation in mechanical properties. At present, the steel used in tinplate has basically been continuously cast.
The chemical composition of tinplate steel can be divided into L, MR, MC, D type 4 according to ASTM A623 standard, and its chemical composition is shown in Table 1. The percentage content of each element listed in the table is the maximum, and the actual content is usually much lower. Among them, L-shaped steel residual elements (Cu, Ni, Cr, Mo and other elements) composition is particularly small, with excellent corrosion resistance, MR Type residual element composition is wider, good corrosion resistance, used as a general food container, MC type P content is higher, play a role in increasing strength, for strength requirements and corrosion resistance requirements are not high purposes, D type is aluminum killing steel, For use in deep drawing or under conditions prone to tensile strain marks. There is also a N type steel, is in L, MR, MC steel nitrogen to improve the strength of the steel, in addition, the United States, Japan some tinplating professional factory using continuous casting method also produced tinplate with quasi-boiling steel and aluminum killed steel.
With the improvement of tin plate production technology, the development of coating corrosion resistance. In order to reduce costs, some products with low corrosion resistance requirements began to use ordinary cold-rolled steel SPCC and SPCD as tinplate substrates.

The hardness is the average value of 2 samples, allowing 1 of them to exceed the specified allowable range by 1 unit. |

a The yield strength is a reference value determined as required. b Yield strength is the average value of the two samples. The sample is P5 in GB/T 228, and the direction of the sample is transverse. c Due to the thickness thinning effect, the elongation is too low and the yield strength cannot be measured. In this case, the yield strength is replaced by the tensile strength. d For the tensile test, the width of the parallel part of the sample is (12.5±1) mm, and the standard distance L0=50mm. Before the test. The sample should be artificially aged for 20min at 200℃. |

5. Usage Precautions for ETP
Modern industrial tinplate is usually a cold-rolled, low carbon sheet coated with commercial pure tin on both sides, which combines the strength and formability of steel with the corrosion resistance, weldability and appearance of tin. Tinplate is widely used in the food industry and a variety of containers, stamped products, packaging materials for non-food industry, such as food cans, spray cans, bottle caps, gas containing beverage cans, packaging materials and non-packaging materials (home appliances, toys, stationery, engineering).
Offers coils and sheets, coil packed in a vertical form or a horizontal.
A label that indicates the manufacturing history is affixed to the outside of the packaging. In addition, a service card is contained inside.
