Aerosol cans and spray cans are different in terms of working principle, use, safety, and filling equipment.
Working principle:
The aerosol can uses pressurized gas to atomize the liquid into a mist, which is suitable for agriculture, gardening, sanitation and fire protection.
Spray cans are driven by hydraulic or electric drive to spray the liquid into a mist, and are mostly used in pharmaceutical spraying, cleaning, disinfection and other fields.
Use:
The spray of the aerosol can is mostly continuous, and the replacement of different nozzles can make the material in the tank spray in different forms, and the scope of application is much wider than that of the spray can.
The spray effect and application range of the spray can are relatively limited, but because it does not involve pressure filling, it is safer to use than the aerosol can.
Security:
Sprays are much safer than aerosols and do not involve pressure filling, so there is no explosive hazard.
Filling equipment:
Aerosol filling equipment includes the bottle in addition to filling materials but also filled with liquefied gas as a propellant, the use of propellant pressure will be the contents of the mist spray.
Spray filling equipment is only filled with contents without propellant. It relies on external force, that is, when using aerosol, manually press the spray head of the bottle mouth to activate a small pump. The pump pushes the liquid into a cavity and then sprays it in mist form from a small hole in the spray head.
In summary, aerosol cans and spray cans have their own characteristics, and they should be selected according to different needs in specific applications.
Cut three samples with a length of 250 mm from one PJ V-ribbed belt, and mark a marking line with a spacing of 100mm at the middle position of the PJ V-ribbed belt. When more than three samples cannot be taken from one PJ V-ribbed belt, samples can be cut from the same batch of PJ V-ribbed belt, but must be indicated in the report. 7.4.2 High temperature resistance test method
Place the sample at 100 ℃ ± 2 ℃ for 96 h ± 1 h and then take it out. After standing at laboratory temperature for more than 2h, bend it along a cylinder with a diameter of 20 mm at a contact angle of at least 90 °.
