Liquid products often contain pigments, active ingredients, or particulate matter. Without agitation, precipitation can accumulate at the bottom of the can, leading to nozzle clogging. A metal ball continuously rubs against the can walls and the liquid surface during shaking, reducing precipitation and ensuring smooth spraying.

Carrying tinplate aerosol cans on board increases the pressure difference between the internal and external pressures, potentially causing them to expand or even explode. Even high-quality cans cannot fully protect against the risks posed by high-altitude, low-pressure environments.

Safely processed tinplate aerosol cans should be collected separately. For households, they can be placed in recyclable metal waste collection bins. For industrial users, they should be stored in a fire-proof, explosion-proof, and well-ventilated area in accordance with hazardous waste storage standards for centralized recycling.

Each tinplate aerosol can has its own tare weight, or empty can weight. After the can is filled with contents and propellant, its weight increases significantly. With use, the weight gradually decreases. When the weight approaches the empty can tare weight, the contents are nearly depleted.

• At room temperature, the pressure inside an aerosol can typically range from 2 to 8 atmospheres. • Once the temperature rises above 40°C, the internal pressure increases significantly, exceeding the design pressure limit of the can material and causing a rupture.

According to the International Energy Agency, the global steel industry accounts for approximately 8% of global industrial carbon emissions, making it the largest contributor to carbon emissions among all industries. Although tinplate sheet production may have slightly lower carbon emissions than conventional steel production, its overall carbon footprint remains relatively large.

The invention of the metal can revolutionized food preservation, most notably significantly extending the shelf life of food. As a sealed packaging method, metal cans can isolate air and bacteria while simultaneously sterilizing food at high temperatures, significantly reducing the risk of spoilage and extending its shelf life.

Tinplate cans typically have a smooth surface with a metallic sheen. This is because the tin coating itself creates a silvery-white reflective effect, while the coating and printing also contribute to the can's glossy appearance.

Tinplate applications of varying thicknesses: 1. Thin Tinplate (0.13mm to 0.20mm) 1.1 Food and beverage cans 1.2 Biscuit boxes and candy packaging 1.3 Cosmetics and perfume containers 2. Medium Tinplate (0.21mm to 0.30mm) 2.1 Food cans 2.2 Paint cans and chemical packaging 2.3 Can caps and closures 3. Thick Tinplate (0.31mm to 0.50mm) 3.1 Large paint cans and chemical containers 3.2 Construction and decorative materials 3.3 Industrial packaging containers

Specifically, the tin plating process design has the following four functions: 1. Preventing oxidation and corrosion 2. Enhancing product safety 3. Maintaining product appearance and quality 4. Improving material processing performance
