1) the adjusting method of the process parameters comprises the following steps:

the curves in the following all refer to the spectral curves in the visible region from 380nm to 780 nm.

1.1 Single-layer and two-layer Gray products

Take CYC140(g/Cr/SiNx) as an example

The thickness of the Cr layer is increased from zero, the transmittance is reduced, the reflection of the glass surface is reduced, the curve is integrally raised, a is more negative, and b is more negative; when the thickness continues to increase, the curve integrally rises, the reflection of the glass surface rises, a is negative, and b is positive; the SiNx thickness is increased from zero, the transmittance is increased, the curve of the glass surface is integrally reduced, the reflection of the glass surface is reduced, and a and b are biased to be positive. When the thickness continues to increase, the glass surface reflection curve rises, the glass surface reflection rises, a is more positive, and b is more negative.

1.2 three-layer Heat reflective product

Take CST140(g/SiNx/CrNx/SiNx) as an example

The thickness of 1-SiNx is increased, and the transmittance is increased; the curve of the glass surface shifts downwards in a short wave, the reflection of the glass surface rises, a is negative, and b is positive; the curve of the film surface moves upwards, the glass surface reflection is reduced, a is negative, and b is positive.

The Cr thickness is increased, and the transmittance is reduced; the spectral curve of the glass surface moves downwards, the reflection is reduced, a is not obvious positive, b is negative, when the thickness continues to increase, the spectral curve of the glass surface moves upwards, the reflection is increased, and b is positive.

The 2-SiNx thickness is increased, and the transmittance is increased; the spectral curve of the glass surface is shifted upwards, the reflection is increased, and a and b are biased to be negative.

1-SiNx and 2-SiNx have great influence on the glass surface.

1.3 Low-emissivity products

CES11-70XT (ZnSnOx/NiCr/Ag/NiCr/ZnSnOx/SiNx) is taken as an example

The low-radiation product has a complex structure, two ZnSnOx interference layers and a SiNx interference layer, so that the low-radiation product has no regularity. The thickness of the interference layer is increased, and the reflection curve is shifted to the right; when the interference layer is thin, the intersection point of the curve is not in the visible light area when the thickness changes, and as the interference layer does not absorb, when the thickness of the interference layer is increased from zero, the transmittance is increased, the reflection is reduced, the reflection curve of the visible light area is integrally moved downwards without the intersection point, and L is reduced; when the thickness of the 2-ZnSnOx is about 25nm, the intersection point enters a visible light area, the reflection at the short wave is increased, the reflection at the long wave is reduced, and L is reduced; as the thickness continues to increase, the reflection curve shifts to the right, the intersection point exceeds 550nm, and L becomes larger. When the thickness of 1-ZnSnOx is 35nm, the intersection point enters a visible light region, the reflection at short wave is increased, and L is reduced. This is also influenced by the thickness of the metal layer. Generally, 2-ZnSnOx, SiNx has a great influence on the color value of the product.

The Ag layer has small absorption and a reversal point in thickness, namely when the thickness is increased from zero, the transmittance is increased, the reflection is reduced, the reflection curve of a visible light region is integrally shifted downwards, and the absorption is increased; when the thickness reaches a certain value, the transmittance is reduced, the reflection is increased, the two ends of the reflection curve of the visible light area are lifted, and the absorption tends to be constant.

The NiCr layer has large absorption and large influence on the transmittance, the thickness is generally increased, and the transmittance is reduced; the glass surface reflection increases and the film surface reflection decreases.

2) Uniformity deviation control standard

2.1 uniformity deviation control Standard

Description of the drawings: the control of the mutation value mainly ensures the integral smoothness of the uniformity curve and avoids the occurrence of the mutation curve (such as a zigzag curve), and the control range of the mutation value refers to the absolute value of the difference value between the maximum value and the minimum value in three continuous points.

2.2 "edge Effect" control Standard

2.2.2 toughened glass: within 50mm of each glass edge, compared with the middle part, delta b is less than or equal to 1.5.

Regarding the edge effect, beyond the above standard, the glass should be inspected under outdoor natural light to see whether the edge effect is obvious.

2.3 tracking and monitoring regulations for Process parameters in production Process

2.3.1 principles for determining Process parameters

Compared with the optical parameter value and the spectral curve of the standard sample plate, the actual optical parameter value and the spectral curve of the continuously produced product have the optical parameter deviation Delta E less than or equal to 1.5. The deviation of the spectral curve in the wavelength range of 500-700nm is less than 1%, the deviation of the spectral curve in the wavelength range of 400-500nm is less than 1.5%, and the deviation of the spectral curve above the wavelength of 700nm is less than 2%.

For the heat reflection coated glass product, the Rg, Lxg, a g and b g values of the glass surface are ensured firstly, and the T% and the Rf, Lxf, a f and b f values of the film surface are ensured secondly.

For the Low-E coated glass product, firstly R, L, a and b of the two surfaces are ensured, and secondly T percent is ensured.

2.3.2 debugging of Process parameters

Before debugging the process parameters, the on-duty engineer must accurately understand the target values of the optical parameters, the allowable deviation ranges, and other process requirements.

2.3.2.1 adjustment of uniformity and color

And setting process parameters according to the film structure of the product. The color of the small sample is adjusted, and the small sample is sent to a product control part for grinding and physical and chemical performance test after the color of the small sample is basically qualified. The uniformity swatch (2400X1000) is then placed while the swatch (1000X300) color is adjusted down. After the uniformity and the color of the small sample are qualified, continuously placing three pots of glass, wherein three pieces are placed in each pot, the first pot of glass and the second pot of glass are waste uniformity pieces, the front surface of the third pot of glass is a uniformity sample, the middle part of the third pot of glass is a half-large piece, and finally. One piece was observed as a homogeneous waste piece. Uniformity and color stability were observed. If the uniformity, the color are stable and qualified, the small sample grinding test is qualified, and the equipment runs stably, the process parameters can be considered to meet the requirements.

2.3.2.2 when the film is qualified, the sample is first tested by the product control part, and the serial number, film code, required testing instrument and optical parameters of the sample are noted.

2.3.2.3 in the debugging process, the engineer and operator on duty must trace the detection curve of the exit photometer and various working curves of the coating equipment every pot, the change of the technological parameters in the debugging process, and simultaneously trace the measurement results of Miniscan and Color XE of the product control part (in the debugging process, each pot of Miniscan must be used for measurement, after the debugging is basically in place, except for the Miniscan for detection, the Color XE must be used for detecting the uniformity sample wafer and the small sample wafer), compare the optical parameters and the spectrum curves of the debugging sample wafer and the standard sample wafer, the previous batch calibration, and make records and necessary explanations.

2.3.2.4 the process parameters are determined, and the complete process parameters, as well as the transmission and reflection optical parameters and spectral curves of the half-size and small sample sheets and the standard half-size and small sample sheets are printed, compared and the necessary instructions are made (time, shift, contract or customer, calibration parameters, etc., the contents are input by the operator into the specified EXCEL file). All the printed data are sorted and filed by the coating section length.

2.3.3 tracking and monitoring in the production Process

2.3.3.1 after the process parameters are determined, production is started. Firstly, checking whether a photometer in a vacuum chamber detects a primary sheet transmittance spectral curve and whether the photometer accords with a primary sheet standard transmittance spectral curve required by a contract; after the product is confirmed to be correct, determining the spectral curves of the transmission, the glass surface and the film surface of the product detected by an exit photometer, comparing the spectral curves with a standard curve and a related curve of a previous batch of products, observing the change of the product curve at any time, observing whether process parameters fluctuate or not if the product curve is abnormal, and simultaneously adding a small sample to measure on a COLOR XE.

2.3.3.2 after production, for example, large glass sheets, the product is monitored for 24 point uniformity and color values with an exit photometer. If the glass is made into small pieces, firstly, an exit photometer is used for scanning 24 points, the middle point of each piece is used as a monitoring point, each pot is used for detection, and the color value of the product at the point is monitored. The monitored optical parameters are entered by the operator into the specified EXCEL file. For the product with the membrane surface on the hollow second surface, recording the optical parameters of the glass surface of the midpoint value every 5 pots; for the hollow product with the membrane surface on the 3 rd surface, the optical parameters of the midpoint value membrane surface are recorded once every 5 pots, and the optical parameters of the midpoint value glass surface are recorded once every 15 pots. The data is processed from the film coating working section longer than the white class arrangement, and the central value of the batch of products is counted and stored in a file for future reference. In addition, a small sample wafer needs to be tracked, delivered to a product control part for detection, and tracked and compared by an engineer or an operator on duty. For varieties produced within three days before target replacement, when four small sample wafers are tracked and the tested optical curves are anastomotic, one small sample wafer is tracked every 1 hour, and three detection instruments are used for measurement and comparison; for varieties produced after three days of target changing or varieties insensitive to color, when two small sample wafers are tracked and the tested optical curves are matched, one small sample wafer can be tracked every three hours, and three detection instruments are used for measurement and comparison. In the event of fluctuations in the exit photometer parameters or process parameters, the frequency of follow-up detection with the small sample slides should be increased to about one slide every 10 minutes. The data are input into a specified EXCEL file by an operator and are sorted and filed by a coating section length.

2.3.3.3, if the data measured by Miniscan and on-line photometer EX SITU both show deviations, but the deviations do not exceed the allowable range, the 300X 1000 plaques are added and measured by COLOR XE. If the differences of the detection results of the three instruments are compared with the respective standard values and are controlled within the allowable range, the process parameters can be finely adjusted without stopping the machine to be close to the standard values.

If the display is out of the allowable range, the production should be suspended and the reason should be analyzed. If the data measured by the COLOR XE and the on-line photometer EX SITU are consistent and inconsistent with the Miniscan detection data, the Miniscan is checked and corrected based on the data measured by the photometer EX SITU.

If the data measured by COLOR XE and on-line photometer EX SITU are contradictory, adding 300 × 1000 small sample, detecting with Miniscan, if the data detected by Miniscan and COLOR XE are identical, producing based on COLOR XE, if producing in white shift, placing the glass in outdoor natural light for observation and comparison, in night shift, placing the glass in simulated daylight for observation, comparing with standard plate, and producing after confirming no error.

If the Miniscan and the on-line photometer EX SITU have the same detection data, the production is carried out by taking the on-line photometer EX SITU as the standard, if the production is carried out in the day shift, the glass is also required to be placed in outdoor natural light for observation and comparison, and the production is carried out in the night shift, the glass is placed in simulated sunlight for observation and comparison with a standard plate, and the production is carried out after the error is confirmed.

2.3.3.4 for the plated film product of the colored original sheet, the on-line photometer EX SITU value is referred to during the production process and the color is compared with the product of the previous batch. If the difference is large, tracking the 6mm AOG white glass is measured with COLOR XE and compared to the standard. If the same difference exists in COLOR XE, referring to 'three'; if there is no difference in the COLOR XE measurement, production is suspended and the reason is found, and simultaneously reported to the coating process engineer and manager. For each batch of tinted glass products, inspection and comparison must be performed outdoors in natural light.

2.3.3.5A special computer is used as a storage tool in the production process, the optical parameters of each batch of products, the corresponding process parameters, the type of original sheet and the production place are recorded and stored in detail, and the production data of each shift must be accurately input into the computer. For the processing sheet with the area exceeding 100m2, a small sample 300X 800mm is made in one pot and delivered to a quality control part for uniformity and grinding test.

2.3.3.6 automatically archiving data every day by using an outlet online photometer EX SITU, and analyzing the color value of the product in the production process of the previous day; the EX SITU automatic archived data is regularly sorted and backed up; the coating process is completed by a long coating section. The method specifically comprises the following steps: and (3) establishing a folder according to the product film code of the detection data of the online photometer of each batch of products, and storing the files of the optical parameters of each batch of products according to the product production date, the film code and the project name. 2013-4-22CES11(beijingliyuandasha)

2.3.3.7 after adjusting the process parameters and tracing the sample, the process parameters and spectral curve are printed for explanation.

2.3.3.8 all the records and the descriptions on the chart are respectively filled out and arranged by the on-duty engineer and the operator (see the respective station responsibilities for details); and collecting and filing by the coating working section.
