4. Food industry
Food grade aerosol cans must comply with food grade safety standards (such as inner wall coatings and propellant selection), with the core advantages of "freshness preservation, convenient access, and controlled dosage". Common categories include:
Cooking aids: edible oil spray (such as olive oil, sunflower seed oil spray, evenly spray on the pot or food materials to reduce oil consumption), baking and demoulding spray (spray on the baking pan to prevent cake adhesion);
Ready to eat/seasoning: spray cream (used for cake and coffee top decoration, press to release, foam is delicate), seasoning spray (such as salt spray, black pepper spray, correctly control the amount of seasoning, and avoid shaking hands).
2、 Industrial and professional fields: Focus on efficient operations to meet specific functional requirements
Aerosol can products in industrial/professional fields are centered around "strong functionality, weather resistance, and adaptability to special scenarios", and are often used in professional scenarios such as mechanical maintenance, automotive maintenance, medical assistance, and agricultural production. They have higher requirements for the formulation of the contents and the pressure resistance of the can body.
1. Automotive industry (maintenance and repair)
In response to the needs of automotive parts lubrication, cleaning, and rust prevention, aerosol cans can penetrate into narrow gaps such as engines and chassis to achieve correct operation. Common categories include:
Maintenance: engine cleaning agent (such as throttle cleaner and fuel injection nozzle cleaner to remove carbon deposits and improve power), lubricating spray (such as door hinge lubricant and window guide rail lubricant to reduce abnormal noise), anti rust spray (sprayed on chassis and hub to prevent rain corrosion);
Emergency maintenance: tire repair spray (after the tire is punctured, it is sprayed into the tire for quick sealing and temporary endurance), glass anti fog agent (sprayed on the inside of the car glass in winter to avoid fog affecting the vision), and paint repair spray (small scratches are temporarily covered to prevent rust).
2. Mechanical and industrial maintenance industry
Used for efficient lubrication, rust removal, and cleaning of factory and mechanical equipment, ensuring long-term stable operation of the equipment. Common categories include:
Lubrication: high-temperature lubrication spray (applicable to high-temperature parts such as motors and bearings, with a temperature resistance of more than 300 ℃), dry lubrication spray (used for gears and sliding rails, to prevent oil stains from adsorbing dust);
Derusting and loosening: derusting agent spray (penetrate the rust gap to loosen the rusted bolt), bolt loosening agent (dissolve the oxide layer between threads to facilitate disassembly);
Cleaning and protection: cleaning agents for electrical equipment (such as circuit board cleaner, which has strong insulation, can be cleaned with electricity to remove dust and oil stains), spray for metal surface protection (forming a protective film to prevent oxidation).
3. Medical and health industry
Medical aerosol cans must comply with pharmaceutical grade standards (such as GMP certification) and are primarily used for "correct drug delivery and local treatment". Common categories include:
Respiratory disease treatment: inhaled aerosol relieves spray, inhales through the mouth, and the drug reaches the lungs directly, with quick effect);
Local treatment: spray for skin administration (such as antibiotic spray, scald repair spray, to avoid infection caused by contact with the wound when applying), oral spray (such as spray for oral ulcer, and spray for throat relief, directly acting on the focus);
Medical auxiliary: medical disinfection spray (such as surgical instrument disinfection spray containing hydrogen peroxide), wound care spray (forming a protective film to isolate bacteria).
4. Agriculture and Horticulture Industry
In response to the demand for "correct application of pesticides, reduction of pesticide waste, and protection of crops", aerosol cans can achieve small-scale and targeted spraying, suitable for home gardening or small-scale planting. Common categories include:

3、 Core advantages of aerosol can application (cross industry commonality)
Whether in civilian or industrial fields, the widespread application of aerosol cans relies on their unique characteristics:
Controllable dosage: The press type valve can correctly control the spraying amount (such as spraying 0.5-1mL per press), avoiding waste or insufficient dosage;
Strong sealing: A completely sealed tank can isolate air and moisture, extending the shelf life of its contents (such as food and medicine, which can be stored for 1-3 years);
Convenient use: it can be operated with one hand without additional tools, especially suitable for outdoor and emergency scenarios (such as vehicle mounted tire repair spray, outdoor mosquito repellent spray);
Uniform coverage: the atomized contents can evenly cover the target surface (such as sunscreen spray and detergent) to improve the effect;
Safe and stable: Modern aerosol cans often use environmentally friendly propellants (such as compressed air, carbon dioxide, replacing traditional fluorocarbons), and the can body has undergone pressure testing (can withstand pressures of 0.8-1.5MPa), making it safe to use.
