Aerosol Tin Cans Products are widely used in people's daily life, involving medicine, cosmetics, food, industrial building materials, daily chemical, fire, automobile care and other fields. The common products are Yunnan Baiyao aerosol, nasal spray aerosol, shaving foam, depilatory cream, moisturizing water aerosol, cake baking oil mist, edible oil mist, kitchen disinfectant, self spray paint, According to the statistics of aerosol industry association in 2017, the output of aerosol in China has reached 2 billion by 2016, with self spray paint accounting for 15.9%, automobile care and industry (including construction) accounting for 29.6% and personal care accounting for 14.9%. It can not be seen that the domestic aerosol products are developing vigorously. In the future, more and more aerosol products will enter into people's lives.

Aerosol concept: Aerosol is a clear liquid, suspension or emulsion made of effective components and suitable propellant in a pressure tight container with special valve system. When used, the content of the agent is sprayed out of mist particles (or foam) by the pressure of the propellant.

Products of Smoke aerosol are as follows: insecticidal aerosol, aerosol gel, aerosol oil, etc

Products of Foam aerosol are as follows: foam cleaning agents for cars, hair mousse, etc

Products of Fine Flow aerosol are as follows: wasp spray, fire extinguisher, etc

Aerosol products belongs to a low-pressure filling. The liquid in the tank passes through the pressure in the tank. When a person's finger touches the button, change the pressure in the tank and spray the liquid out of the tank. The atomization effect of the liquid is different through the nozzle and the nozzle with different aperture size. Conventional aerosol products are generally completed by three steps of filling, sealing and inflation. Special products involve precipitates or color paste, such as self spray paint and snow ribbon. Before or after filling liquid, one or two glass beads need to be placed, which can disperse the color paste in the tank during use, so as not to cause color difference or uneven spraying of the ejected products. In addition, binary aerosol is also available. The production process of the product is opposite to that of the conventional aerosol production. The product is first inflated, sealed and filled with liquid. This kind of product is applicable to the water-based liquid, the original liquid is corrosive or easy to react with air and other gases. The original liquid does not contact with the gas, and the pressure in the tank is filled between the bag and the bottle wall. When the liquid is filled into the bag, the volume between the bag and the bottle wall decreases. The pressure is increased to ensure that the finished product pressure can make the liquid in the bag spray out.

Propellant: the motive force for the effective components to spray out, sometimes they have the solvent effect of the effective components.
