Description
Technical field
The application relates to observation window field, particularly relates to a kind of power equipment observation window.
Background technology
Power equipment includes generating equipment and power supply unit, is to apply a wide kind equipment, and it is typically placed in cabinet
Internal, it is carried out certain protection.
But, due to the difference of breathability, poisture-penetrability and temperature, it is placed easily there is water inside the cabinet of power equipment
Mist, is attached on observation window surface, easily causes the observation difficulty of operator, enters heat and bring inconvenience use.
Summary of the invention
It is desirable to provide a kind of power equipment observation window, to solve problem set forth above.
Embodiments of the invention provide a kind of power equipment observation window, comprises observation window framework and sight glass, institute
Stating observation window framework to be located on power equipment cabinet, described observation window framework is provided with installing hole, and described sight glass is antifog
Glass substrate.
The technical scheme that embodiments of the invention provide can include following beneficial effect:
In the power equipment observation window of the present invention, sight glass is antifog glass substrate, and this antifog glass substrate surface is provided with
Antifogging coating, it is less than 1 degree to the contact angle of water droplet, has preferable hydrophilic effect, it is possible to prevent glass substrate surface from occurring
Water smoke etc., thus solve problem set forth above.
Aspect and advantage that the application adds will part be given in the following description, and part will become from the following description
Obtain substantially, or recognized by the practice of the application.It should be appreciated that above general description and details hereinafter only describe
It is exemplary and explanatory, the application can not be limited.
Accompanying drawing explanation
The invention will be further described to utilize accompanying drawing, but the embodiment in accompanying drawing does not constitute any limit to the present invention
System, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain according to the following drawings
Other accompanying drawing.
Fig. 1 is the structural representation of power equipment observation window of the present invention.
Fig. 2 is the Making programme figure of antifogging coating of the present invention.
Detailed description of the invention
Here will illustrate exemplary embodiment in detail, its example represents in the accompanying drawings.Explained below relates to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represents same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the present invention.On the contrary, they are only with the most appended
The example of the apparatus and method that some aspects that described in detail in claims, the present invention are consistent.
Transparent material has a wide range of applications in industrial and agricultural production and life, but, due to the impact of surrounding, special
Not being the impact of humidity in environment, transparent material surface easily produces atomization, causes transparency to decline, to production and the life of people
Live and bring inconvenience, even cause heavy losses.
Anti-fogging measure is mainly started with from the condition destroying fogging, and one is from thermodynamics, installs heater and makes base material
Surface temperature is higher than steam dew point, or the little dewdrop that installation ultrasound wave dispersion makes steam produce volatilized within the extremely short time
For steam, the measure being usually taken is the method heated with hair dryer or film metal silk, removes transparent material surface
Water smoke；Two is from the performance changing material surface, changes chemical composition or the microstructure of substrate surface, such as at not shadow
In the case of ringing the function of material own, construct one layer of hydrophilic or hydrophobic wear-resistant coating at material surface, when little water drop contact
During to this coating, due to the hydrophilic of coating or hydrophobic effect, little water droplet can coating surface sprawl into thin layer moisture film or
Person tumbles, thus inhibits the formation of coating surface water smoke.
But, in prior art, using hair dryer or tinsel heating, there is device complicated, original paper is many, cost
Height, the problem such as fragile, therefore coating is the main method solving transparent material surface fogging.

A) Substrate treatment, using volume ratio is the 98%H of 7:32SO4And 30%H2O2To high temp glass substrate immersion treatment,
The high temp glass substrate distilled water wash that will process, then dry up with nitrogen；
B) the high temp glass substrate after cleaning alternately is immersed in PDDA and PSS solution, and distilled water wash thing is used in centre
PDDA and PSS of reason absorption, covers until obtaining obtaining 7 layers of PDDA and 6 layers of PSS at high temp glass substrate surface；
C) high temp glass substrate obtained above is immersed in the CaCO that step 3 obtains3/SiO2Compound particle suspension
In, stand 5h, deposit one layer of CaCO at high temp glass substrate surface3/SiO2Compound particle coating, then by this high temp glass base
Sheet is put in Muffle furnace, sinters 10h so that CaCO at 600～850 DEG C3/SiO2CaCO in compound particle3Pyrolytic,
The SiO of coarse structure and pore structure is had to deposition2The high temp glass substrate of hollow ball coating.
