With the development of the economy, the growth of consumption level and the improvement of people's concept of environmental protection, the improvement of national safety regulations and environmental protection regulations, the market has put forward new requirements for the aerosol industry. The aerosol should not only release the content, but also Moreover, it is necessary to ensure safe and efficient use after a period of storage or use. These requirements are driving changes in the structure of aerosol products. With the continuous increase of the types of aerosol valves, the applicable fields have been widely expanded, but there are three important indicators in the process of adjusting the product structure of aerosol valves that cannot be ignored. The following aerosol filling machine manufacturers give you Briefly introduce these three important indicators. 1. The pressure resistance of the aerosol valve The pressure of the aerosol is mainly derived from the pressure of the propellant in the tank. The pressure here is mainly from the pressure of the propellant in the tank. Generally, the pressure is about 0.5MPa at 23°C, but the pressure in the tank will increase as the temperature increases, such as LPG The pressure of the propellant such as DME and DME varies greatly with the temperature. The fixed cover is the most important part of the aerosol valve to withstand the pressure. In the industry, it is usually stamped with 0.27mm thick tinplate or 0.42mm thick aluminum, and generally can withstand about 2.0MPa. For high-pressure products such as fire extinguishers, thicker materials need to be used to increase their compression resistance. Tinplate with a thickness of 0.42mm can be used as the sealing cup material. 2. The tightness of the aerosol valve The sealing ring is assembled in the valve body, called the inner gasket, which forms a complex sealing relationship between the valve body, fixed cover, and valve core parts. Unlike the outer gasket, this is a dynamic sealing point and is in direct contact with the solvent in the tank. It is the most common and main sealing point for aerosol valve leakage, so the sealing ring is the top priority in the production of aerosol valves. 3. Corrosion resistance of aerosol valve The inner surface of the aerosol valve is in direct contact with the contents of the aerosol. If the product formula is not well controlled in terms of corrosion resistance, otherwise there is a possibility of corrosion of the components of the aerosol valve. For example, in water-based formulations, if the fixed cover is produced from tinplate without surface treatment, it is easy to develop corrosion spots, followed by perforation leakage. In this case, you should choose tinplate or aluminum fixed cover with internal coating. It is also worth mentioning that there are very few formulas that will cause corrosion or dissolution of the valve body, mainly because the product solution contains harmful substances to the va...

How Do Aerosol Cans Work? Understanding how an aerosol can works is important in understanding aerosol can propellants and their purpose. Aerosol cans are a dispersal system that relies on internal pressure to propel the product out of the can in the form of an aerosol. Aerosol cans typically consist of some variation of these four components: The container The trigger The nozzle The straw or hose The container is pressurized so that when the trigger is pressed, the product within the can is pushed through the straw and outward from the nozzle in the form of a fine mist or aerosol.

Aerosol and spray packaging have become an indispensable product unit for various brands. Many varieties will benefit from the consumption upgrading policy and gain opportunities for rapid development. The exhibition area of the 10th Aerosol Exhibition will reach 20,000 square meters, and it is one of the world's largest and most influential communication platforms for the industry chain of aerosol and spray products. Exploring the international market, promoting industrial innovation, and expanding industry exchanges are the purposes of this event. Let us work together to obtain the latest market information, learn about industry innovations, and shorten the time for transformation and upgrading in the context of consumption upgrades in a rapidly changing market.

The history of aerosol tin cans dates back to the early 20th century when they were first developed as a way to dispense insecticides. The first aerosol can was invented in Norway by Erik Rotheim in 1926, and it used a crimped-on valve to control the flow of the product. However, it was not until the 1940s that aerosol cans became widely used, particularly during World War II when they were used to deliver insecticides and other chemicals to control pests and diseases. In the years that followed, aerosol cans became increasingly popular for a wide range of applications, including paint, air fresheners, and hair spray. One of the major innovations in the development of aerosol cans was the introduction of the LPG (liquefied petroleum gas) propellant in the 1950s. This made it possible to deliver products more efficiently and with greater precision, and it allowed for the development of new types of products, such as foam cleaners and lubricants. Another major development in the history of aerosol cans was the introduction of the one-piece can in the 1960s. This eliminated the need for a separate valve and reduced the risk of leakage, making the cans more reliable and easier to manufacture. The one-piece can also allowed for the use of more sophisticated valves, such as the metered-dose valve, which made it possible to deliver precise amounts of medication in the form of inhalers and nasal sprays. Over the years, the design of aerosol cans has continued to evolve, with improvements in materials, coatings, and printing technology. For example, the use of plastic coatings and inks has made it possible to create more attractive and durable labels and designs, while advances in can design and manufacturing have made it possible to produce cans with greater precision and consistency. Today, aerosol tin cans are widely used in many industries for their convenience, reliability, and versatility. They continue to be an important type of packaging for a wide range of products, and their design and technology are likely to continue evolving in the years ahead.
