Diameter is 3 mm, and with a thickness of 2 mm, for the sealing cover with a thickness of 3 mm, diameter is 8 mm.
The ethanol solution can be mutually immiscible with water-based spray liquid or oil base spray coating liquor.
The working principle of above-mentioned spray equipment is as follows: when spray coating liquor by standard interface initially enter cavity inside diameter compared with
Big region enters the lesser region of diameter behind the shrinking zone of cavity, in this course, the region spraying being relatively large in diameter
The lesser region spraying flow velocity of the flow velocity diameter group of liquid is slow, and according to Bernoulli equation, the pressure in the region being relatively large in diameter is greater than
Lower area, spray coating liquor can be flowed into from tiny entrance above under the driving of the pressure difference, drive the internal ethyl alcohol molten
Liquid is flowed out from following small outlet, is mixed near the jet expansion with spray coating liquor and is ultimately formed fine droplet ejection.
And Bernoulli Jacob's pressure difference is related with the flow of spray coating liquor, and the fast pressure difference of flow is big, which can mix according to uninterrupted auto-control
The number of amount entered.It all can be this rodlike with small rod-shpaed particle entrained by ethanol solution in the fine droplet sprayed in this way
Reticular structure easy to form between particle, thus effectively inhibit spray coating liquor in surrounding from sprayed particle to drop orientation
Migration, guarantees the uniformity of final spraying effect.
The working principle of above-mentioned spray equipment is as follows: when spray coating liquor initially enters the sky by the standard interface
The region that intracavitary portion is relatively large in diameter, behind the shrinking zone of cavity enter the lesser region of diameter, in this course, diameter compared with
The flow velocity diameter group of big region spray coating liquor lesser region spraying flow velocity is slow, according to Bernoulli equation, the area that is relatively large in diameter
The pressure in domain is greater than lower area, and spray coating liquor can be flowed into from tiny entrance above under the driving of the pressure difference, drives inside
The ethanol solution is flowed out from following small outlet, mixed near the jet expansion with spray coating liquor ultimately form it is micro-
Droplet sprays.And Bernoulli Jacob's pressure difference is related with the flow of spray coating liquor, and the fast pressure difference of flow is big, which can be according to uninterrupted
