Description
Technical field
The present invention relates to a kind of film plating process, and in particular to a kind of film plating process of photovoltaic self-cleaning glass belongs to from clear
Clean nano thin-film technical field.
Background technique
For photovoltaic plant, the cleaning of photovoltaic module surface photovoltage glass is most important, the ash of photovoltaic glass surface
Dirt, dirty etc. can cause the decrease in transmission of sunlight, lead to the lower power production of photovoltaic plant, influence power station income, therefore
Periodically photovoltaic module surface must be cleaned during the O&M of power station, but many power stations are in the serious area of dust accretions
Domain causes to clean frequency height, heavy workload, the cost of labor of power station O&M is increased, so the exploitation of self-cleaning glass is to light
It is most important for volt industry.
Currently, self-cleaning glass is broadly divided into Superhydrophilic and super-hydrophobicity two major classes.And in Superhydrophilic automatically cleaning glass
Titanium dioxide is because it is with characteristic of semiconductor in glass, and not only there is super hydrophilic characteristic may be used also under the action of photocatalysis on its surface
With decomposing organic matter.
Currently, substantially using the film-forming method of solution-gel technology, physically or chemically vapour deposition process, electrodeposition process, work
Property nano-TiO2Powder is film-made method, but its adhesion, stability and uniformity are all bad.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of easy to operate, effectively improve adhesion,
The film plating process of the photovoltaic self-cleaning glass of stability and uniformity.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
A kind of film plating process of photovoltaic self-cleaning glass, comprising the following steps:
S1: after a certain amount of butyl titanate and octadecanoid acid sodium are mixed, adding a certain amount of dehydrated alcohol, after stirring,
It stands and saves, mixed solution is made；
S2: mixed solution is coated in glass surface using coating machine by cleaning glass surface；
S3: the glass after high-temperature calcination coating forms the TiO of nanostructure in glass surface2Film.
Butyl titanate in the above-mentioned steps S1 volume fraction in mixed solution is 5% ~ 25%, and octadecanoid acid sodium is mixing
In solution volume fraction be 3% ~ 10%, volume fraction of the dehydrated alcohol in mixed solution be 65% ~ 92%, mixing time be 20 ~
60min, whipping temp are 60 ~ 75 DEG C.
In above-mentioned steps S2, cleaning solution is dehydrated alcohol.
Coating rate in above-mentioned steps S2 is 1500 ~ 4000r/min, is coated with 1 ~ 5 drop/sec of speed.
High temperature in above-mentioned steps S3 is 500 ~ 600 DEG C, and calcination time is 1 ~ 3h.
TiO in above-mentioned steps S32Partial size is 30 ~ 80nm.
The invention has the beneficial effects that:
A kind of film plating process of photovoltaic self-cleaning glass of the invention, by using special Incineration Mechanism so that mixed liquor in
On glass surface, is integrally calcined with glass, form the nano-TiO in conjunction with glass surface2Overlay film；The film plating process is easy to operate, makes
With conveniently, plating effect is good, and the adhesion of film is good, compares existing solution-gel technology, and the heat based on high temperature dissipates effect, receives
Rice TiO2With preferably scattered property, and after high-temperature process, TiO2The stability of structure is more preferable, TiO2The degree of purity of film is more preferable；
Plating process is not necessarily to additional clean room and atmosphere protection, has stronger anti-impurity interference；Pass through nano-TiO2What film had
Photic Superhydrophilic and photocatalysis characteristic not only can form moisture film isolation pollutant attachment in glass surface, moreover it is possible to which degradation has
Machine pollutant has self-cleaning property；The photovoltaic plant that finished product after its plated film applies to, so that the cost of labor of its O&M obtains
It is effectively reduced, the electricity generation system in power station is more efficient, can additionally improve about 2 ~ 5%.

Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
A kind of film plating process of photovoltaic self-cleaning glass, comprising the following steps:
S1: after the butyl titanate of volume fraction 20% and the octadecanoid acid sodium of volume fraction 6% are mixed, volume fraction is added
74% dehydrated alcohol persistently stirs 30min, and whipping temp stands at a temperature of being 65 DEG C, 60 DEG C and saves, and mixed solution is made；
S2: being cleaned glass surface using dehydrated alcohol, is reused coating machine for mixed solution and is coated in glass surface, applies
Covering rate is 3000r/min, is coated with 3 drops/sec of speed；
S3: the glass after coating is calcined at 550 DEG C, calcination time 2h is broken carbochain, only TiO2Stay in glass table
