Many people don't know what tinplate is, but in fact, tinplate is a metal material.Why it is called tinplate? Because a layer of tin is electroplated on the outside of the iron plate. That's the reason that we call it tinplat iron.Why are aerosol cans almost always made of tinplate?   The liquid inside the aerosol can is formed by compressing a certain gas with a gas compressor. The pressure inside the can is much higher than the outside air pressure, so the aerosol sprays out in the form of a white mist, all of which are nanometer-sized. If you want to withstand items with high pressure, the rigidity of the aerosol can must be very strong, otherwise it will easily deform or even explode. Therefore, when choosing packaging for aerosol spray, metal materials must be the most suitable, such as stainless steel or tinplate.Let's compare stainless steel cans and tinplate cans to see why tinplate is the best metal meterial to making aerosol cans.As we all know, stainless steel not only has high rigidity but also does not rust!Its service life is very strong, so it is a good choice for packaging. However, it also has its disadvantages that  is too expensive!As for the tinplate can, firstly, it is with high rigidity and not rusting. Second, Its elasticity is strong, and it can be molded into various shapes of aerosol cans, such as round cans, square cans, spherical cans, and irregular cans, etc.Additionally, it can meet all your requirements. Another important point is that in the metal packaging industry, the price of a tin can is very cost effective. Because In the market, the price of iron is cheaper than that of aluminum and stainless steel.In summary, the advantages of a tin can are: high rigidity, non-transparency, good sealing, no rust, green and environmentally friendly, and recyclable.

The application history of the three-piece can has been nearly 200 years, although it has been improved many times, its basic composition is still made of three metal sheets (mostly tinplate) from the body of the can, the bottom of the can and the lid of the can, so it is named "three-piece can". Its shape, size and manufacturing method of the bottom and lid of the ordinary three-piece can are exactly the same, collectively referred to as the lid. There are two main sealing forms of the longitudinal seam of the tank body: tin welding and fusion welding. The former was used earlier, but it has been eliminated because of the lead in the solder. The latter can avoid lead pollution, low energy consumption, less material consumption, but the production equipment is complex.   The three-piece can has the characteristics of good rigidity, can produce cans of various shapes, high material utilization rate, easy to change size, mature production process, and many kinds of packaging products.

For the whole aerosol products, aerosol cans are an important part, it not only bears the role of the appearance of the packaging, but also adhere to the responsibility of the product leakage. At the same time, aerosol cans as the main body of high pressure resistance, but also aerosol product leakage, corrosion of the high incidence of the site. So how to select the aerosol cans, the production of aerosol products, is the first and second most important.Usually we are classified according to the material of the can. Currently, there are two common types on the market: tinplate aerosol cans and aluminium aerosol cans.Among them, tinplate cans are the aerosol products in larger quantities, but also more affordable aerosol cans. From the shape can be divided into straight-wall cans, necked-in cans and so on. Necked-In Cans Straight-Wall Cans   From the internal coating, can be divided into plain cans and internal coating cans. Plain Inside                                                Golden Lacquered Inside   From the manufacturing structure can be divided into three-piece cans, two-piece cans and so on. Three-piece Cans   Guangdong Sihai specialises in manufacturing three-piece empty aerosol tin cans, with 25 years of experience, and has been committed to producing the safest aerosol cans.

Key points for choosing aerosol cans 1. Stability/compatibility For any aerosol can product, the first thing is to ensure the stability and reliability of the product. The cans of the selected products are tested for compatibility and stability based on the type of product and the characteristics of the formula. Only with data support can we have a theoretical basis for products to flow into the market. Of course, the stability test does not mean that there is no problem 100%. It is only a representative test. There may be unknown problems in the follow-up, but it can represent the vast majority. 2. Security Safety is the first priority for any project. The safety here includes usage safety, pressure safety, environmental safety, toxicological safety, the proportion of the contents in the aerosol can’s full water weight, etc. What R&D engineers develop is not only products that can bring profits to the boss, but more importantly, safe products that can bring benefits to society. 3. Economical Excessive use of packaging materials is actually a waste of resources, so choosing suitable packaging materials is a suitable way to protect resources.

The working principle of aerosol canister spray mainly depends on the internal pressure,and the interaction of the liquid and the nozzle. The inside of the aerosol tank is usually filled with liquid and compressed gas, and the pressure of the compressed gas forces the liquid to spray out through the outlet nozzle. When the nozzle button is pressed, the nozzle opens, causing the compressed gas and liquid to mix  and spray out. Inside the aerosol tank, the compressed gas usually exists in liquid form, and when the nozzle button is pressed, the liquid gas is quickly evaporated into a gaseous state, while forcing the liquid to spray out through the outlet nozzle. The fluidity of liquid is the key factor for its application in aerosol canister spray, and the choice of liquid has an important effect on the spray effect. In addition, the structure of the nozzle also plays a decisive role in the spray effect. For example, a nozzle with a porous core or a non-porous core can subdivide the ejected liquid into tiny fog particles, making the liquid more delicate and uniform after the ejected
