First, the scope of application
Aerosol products are widely used in people's daily lives, involving pharmaceuticals, cosmetics, food, industrial building materials, daily chemical, fire fighting, automotive care and other fields. Common products: nasal spray aerosols, Shaving foam, depilation cream, moisturizing aerosol, cake baking oil and gas mist, edible oil mist, kitchen disinfectant, spray paint, rust inhibitor, cleaning agent, insecticide, air freshener, carburetor Cleaning agents, fire extinguishers, etc. According to statistics of the Aerosol Industry Association in 2017, by the end of 2016, China's aerosol production reached 2 billion, 15.9% from paint, 29.6% from automobile care and industry (including buildings), and Care accounted for 14.9%. It can not be seen that the products of domestic aerosols are developing vigorously. In the future, more and more aerosol products will enter people's lives.
Second, aerosol product introduction
The aerosol product belongs to a low-pressure filling. The liquid in the tank passes the pressure in the tank. When the human finger touches the button, the pressure in the tank is changed, and the liquid in the tank is ejected through the nozzle. Aperture-sized nozzles have different spray effects on the sprayed liquid. Conventional aerosol products are generally completed in three steps: filling, sealing, and inflating. Special products involve deposits or pastes, such as paints and snow ribbons, which need to be placed before or after filling liquids. One or two glass beads can be used to disperse the colorant in the tank during use, so as to prevent the ejected product from having chromatic aberration or uneven discharge; in addition, there are binary aerosol products and its production process. Contrary to conventional aerosol production, inflate, seal, and fill. These products are suitable for water-based liquids, aerosols that are corrosive or react with air and other gases. The raw liquid and the gas are not in contact, and the pressure in the tank is filled between the bladder and the wall of the bottle. When the liquid is filled into the bladder, the volume between the bladder and the wall of the bladder is reduced, and the pressure is increased, so that the pressure of the finished product can be ensured. The liquid in the bladder is sprayed.
Third, aerosol product production process
The aerosol production process is broadly divided into three steps. First, the production of the raw liquid is generally carried out using a reaction vessel to produce agitation. Depending on the product produced, the reactor needs special specifications, such as jacket heating, vacuum pumping, and circulation. Emulsification, mechanical seal, explosion-proof, etc.; second step, aerosol filling equipment needs to be equipped, and aerosol equipment is selected according to the products produced; in the third step, the product is sampled and tested, and the packaging box is inserted into the finished product. Warehouse.
We use paint sprays and cleaning agents as examples. Self-spraying paints are widely used in industries such as industry, electric power, furniture, and automobiles. In addition to the different colors, the production processes are the same. The water-based paints will be used in the future. Is more widely used in various fields, are environmentally friendly products, in the paint production process, attention should be paid to the color difference and the addition of curing agent, for the production of paint, mainly consider the safety awareness of the workshop, the gas filling is a liquefied gas, scientific name Dimethyl ether, the gas is flammable and explosive, it is not allowed to add dimethyl ether to the gas in civilian use, because dimethyl ether is corrosive to rubber, but in the production process of our aerosol products, It is a good catalyst, especially in the production of oily paints. It can be well compatible with paints, so that the aerosol paint can achieve the effect of spraying with the spray gun. There are many types of aerosol cleaners currently used in the market for cleaning agents. There are many kinds of aerosol cleaners used in the market. There are daily-use household oil cleaners and industrial cleaners. The production process is the same, but the production of the original fluid is different, are the first filling of the original liquid - sealing - inflatable.
