Detailed description of the invention
Fig. 1 is production technological process of the invention.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be described in further detail.
A kind of processing method for eliminating BIPV component bubble, method and step are as follows:
In production scene, Temperature and Humidity Control is under the premise of temperature≤22 DEG C, humidity≤30%RH, it is first determined production
BIPV size of components determines that BIPV component in the occupy-place of laminating machine heating dish, is placed respectively on four sides of BIPV component occupy-place
Four point thermometers carry out temperature detection, guarantee the difference of each point thermometer measured temperature less than 2 DEG C.Any two point thermometer institute thermometric
When the difference of degree is more than or equal to 2 DEG C, i.e., when temperature deviation is big, laminating machine oil circuit is checked in time and is repaired.It ensure that integral layer
The stability of press heating dish, reduce PVB fusion caused by the inhomogeneities due to laminating machine heating dish temperature it is uneven,
A possibility that the problems such as poor mobile performance, generation bubble, occurs.
The dedicated laminating machine air bag of photovoltaic is through use after a period of time, the intrinsic print of BIPV component before having formd
Note, if the overall surface flatness of the laminating machine air bag cannot match with BIPV component to be processed.Need to check lamination
Whether machine air bag forms the intrinsic marking, i.e. laminating machine air bag flatness detection process.If the intrinsic marking that laminating machine air bag is formed
It cannot coincide with BIPV component, need to replace laminating machine air bag, ensure that entire BIPV component in lamination process
Flatness so that the marking of laminating machine air bag fits like a glove with BIPV size of components, reduce due to BIPV component pressure not
A possibility that uniformly generating bubble.
Then, it needs to carry out material to upper layer tempered glass, lower layer's tempered glass, lower layer PVB, battery strings group, upper layer PVB
Preparation.
It is required that glass producer is producing upper layer tempered glass and when lower layer's tempered glass, to upper layer tempered glass and lower layer's steel
Change glass to carry out guaranteeing the curvature of upper layer tempered glass and lower layer's tempered glass, thickness, length variation in certain public affairs with piece
Within the scope of difference (curvature, thickness, length the margin of tolerance be shown in Table one, table two, table three respectively).
Table one, curvature tolerance
| Nominal thickness (㎜) | Arch tolerance (%) | Waveform tolerance (%) |
| 3.2、4 | 0.25 | 0.2 |
| > 4 | 0.3 | 0.2 |

Table three, thickness deviation
| Nominal thickness | Thickness tolerance |
| 3.2、4、5、6、8、10、12 | ±0.2 |
| > 12 | ±0.3 |
In carrying out BIPV component laying process production process, if upper layer tempered glass and lower layer's tempered glass camber are different
It causes, then upper and lower two panels tempered glass misalignment, causes bubble to generate more.Therefore, for the assurance of raw material, i.e. tempering glass
The inspection of glass and the monitoring for laying process are the key that solve to generate air bubble problem.The present invention is to upper layer tempered glass under
Layer tempered glass guarantee that upper layer tempered glass and lower layer's tempered glass camber are consistent with piece, guarantee upper layer tempered glass
It aligns with lower layer tempered glass, considerably reduces a possibility that bubble generates.
Before carrying out BIPV component laying process, need that upper layer tempered glass and lower layer's tempered glass dry
Processing purges upper layer tempered glass and lower layer's tempered glass, is dried, removing impurity removing, guarantee upper layer tempered glass and
The drying of lower layer's tempered glass is avoided since the steam of upper layer tempered glass and lower layer's tempered glass enters BIPV component internal
And a possibility that generating bubble.
It successively carries out lower layer's tempered glass, lower layer PVB, battery strings group, upper layer PVB, upper layer tempered glass to stack laying,
Complete the conjunction piece of BIPV component.
In process of production, the middle night shift temperature difference is big, will lead to BIPV component and generates after laminating machine discharging and expands with heat and contract with cold now
As making the edge of BIPV component generate bubble and by the enlarged in thickness of lower layer PVB and upper layer PVB, in order to solve this problem
It asks lower layer PVB and upper layer PVB that can wrap lower layer's tempered glass and upper layer tempered glass edge, and then efficiently avoids lower layer
A possibility that PVB and upper layer PVB generates bubble because generating thermal expansion and contraction.
To close the BIPV component after piece be put into laminating machine preheated, precompressed processing, the BIPV component after pre-molding puts
Set in the dehumidifying being separately provided into workshop, the Temperature and Humidity Control between dehumidifying exists: temperature is 20-25 DEG C, humidity 25%-
30%RH.Setting between dehumidifying efficiently avoid due to the particularity that PVB material absorbs water is by moisture absorption in workshop
BIPV component internal generates a possibility that bubble.
If bubble occurs in the BIPV module edge surrounding after pre-molding, needs to process product, be existed using diameter
The round steel needle of 0.5~1.5mm punctures bubble, or in BIPV module edge sandwiched C-type clamp, in BIPV module edge bubble
Intensive region, it is light to turn 3/4 circle close to multiple C-type clamp of sandwiched, in the sparse region of BIPV module edge bubble, in distance
Region sandwiched C-type clamp of bubble 5mm, the edge of no BIPV module edge bubble area, at interval of the length of 5 C-type clamp
One C-type clamp is set, it is light to turn 3/5 circle.
Dibutyl ester is smeared in BIPV component surrounding, for accelerating lower layer PVB and upper layer PVB to melt, prevents bubble from generating.
BIPV component is finally put into autoclave and carries out curing process, and by temperature fall time control 30-40/, it is high
The control of pressure kettle temperature fall time is conducive to control the generation of extra bubble.
It needs to carry out quality inspection to it after the completion of the production of BIPV component, and it is packed.
