The application field of the aerosol filling machine has good water solubility and solvent performance in dimethyl ether, especially in products with high polymer as the main component and water-based products. It can be used as a propellant for water-based aerosols. In 1928, the Norwegian Eric Rötlleim (the inventor of aerosol packaging) used dimethyl ether as an aerosol propellant. After years of testing the quality and safety of dimethyl ether, dimethyl ether has been widely used in the foreign aerosol industry. The United States has used dimethyl ether as a propellant for two antifungal aerosols. my country’s Shunde People’s Hospital and Guangzhou Xiangxue Pharmaceutical Co., Ltd. have successfully produced a new generation of environmentally friendly surface anesthetic lidocaine aerosol with dimethyl ether as a propellant, which has become a new type of medical gas that replaces Freon as a propellant. Aerosol. Paper testing.
The aerosol filling machine absorbs foreign advanced technology, and the filling head is individually controlled, and no cans are produced; the sealing head adopts guided sealing, if the sealing quality is not high, the machine will automatically stop; the filling head adopts guided inflation, which is accurate and accurate. Very little gas consumption. It can be equipped with automatic valve loading machine, automatic weighing machine, automatic nozzle pressing machine, automatic capping machine and inkjet printer.
The difference between aerosols and most other dosage forms is that the packaging of these preparations requires pressure-resistant containers, valve systems and special production equipment, so the product cost is relatively high. In addition, propellants (mainly chlorofluoroalkanes), which are an important part of aerosols, can destroy the ozone layer and have serious environmental protection problems. Moreover, reaching a certain concentration in animals or humans can sensitize the heart and cause arrhythmia. .
