Man in Hospital after Explosion; Victim Burned When Aerosol Can Blew Up in His Face
aWhen relative movements of aerosols bring particles into contact, they bind together as a result of surface free-energy or Van der Waals forces. Relative movements between aerosol particles can be produced by three different mechanisms: Brownian motion, gravitational settling and turbulence. 当湿剂的...
A spring, with one end supported within the conduit of an aerosol can via crank, has another end pressed against a ball, which in turn normally closes the orifice of a plug at the conduit end. When the internal pressure of the can exceeds a maximum established value, the ball counters th...
a因此当患者在吸入较冷的药雾气流时,吸入的雾化量减少,人体能吸收的药物剂量更进一步减少 Therefore works as patient when inspiration cold medicine fog air current, the inspiration atomization quantity reduces, the human body can absorb medicine dosage further reduction[translate]...

The spray head for an aerosol can has a base (19) which fits on to the can. A button attached to the base operates the head (4) of the aerosol valve (3). This is connected to a spray jet (10) by a tube (8). A hinged cap (5) fits over the head when it is not in use...
Aerosol spray can with safety valve uses nonreturn valve integrated in fill hole to shut this independent of bung screw when can is pressurised.The over-fill safety device (2) uses a prefered screw (4) in the suitably threaded fluid fill hole (3) and a non-return valve (11) integrated ...
The can holds liq. or paste inside a flexible bag into which the head and nozzle fit; gas pressure on the bag ejects the contents through the nozzle. The can is to contain chemicals in separate compartments with a frangible partition between; when a manual pressure fractures the partition, ...
