Description
Technical field
The present invention relates to silver-colored slurry viscosity pick-up unit for a kind of cell piece, relate in particular to silver-colored slurry viscosity Thermostatic detection device, more specifically say the constant temperature water tank in silver-colored slurry viscosity Thermostatic detection device.
Background technology
A kind of thick mixture slurry that silver slurry is comprised of particulate, bonding agent, solvent, the auxiliary agent of highly purified (99.9%) argent.It is very strict that conductive silver paste requires its component.The particulate of argent is the Main Ingredients and Appearance of conductive silver paste, and the conductive characteristic of solar cell is mainly to embody by it.The content of argent in slurry is directly relevant with electric conductivity, and the content of silver is high, to the electric conductivity that improves it, is useful, but, when its content surpasses critical volume concentration, its electric conductivity can not improve.General silver content is in 80～90%(weight ratio) time, oneself reaches mxm. electric conduction quantity, when content continues to increase, electrically no longer improves, and resistance value is in rising trend; When content, lower than 60% the time, the variation of resistance is unstable.In concrete application, in the silver slurry, silver-colored fraction of particle should be considered stable resistance, restricted by the factors such as curing characteristics, bonding strength, economy, as too high as silver-colored fraction of particle, be bonded the probability that resin wraps low, after film-forming, the bonding force of silver conductor descends, the danger that has silver granuel to come off.So the content of the silver in the silver slurry is generally suitable at 60-70%.
The viscosity of silver paste of solar cells has directly affected light-receiving area and the cell photoelectric conversion efficiency of solar cell surface, and it is a very crucial technology of making in solar cell.If silver-colored slurry viscosity is on the low side, although the good fluidity of slurry, after printing, grid line caves in greatly at silicon chip surface, has increased the shading-area of solar cell surface, reduce the light-receiving area of solar cell surface, reduced the photoelectric transformation efficiency of solar cell in unit area; On the contrary, if viscosity is higher, although the silver slurry prints rear grid line, be not easy to cave in, highly viscous slurry is difficult for printing, easily lumps, and electrical property is unstable.Therefore, in the preparation process of silver slurry, must be tested the viscosity of slurry, at present, test silver-colored slurry viscosity and usually use rotational viscosimeter.Experimental results show that: temperature deviation is very large to the viscosity influence of battery silver paste, and temperature raises, and viscosity descends.When 0.5 ℃ of temperature deviation, its viscosity number deviation surpasses 5%, therefore, when measuring battery silver paste viscosity, must in constant temperature enclosure, carry out, also silver slurry to be checked must be placed in constant temperature enclosure and deposit enough time before detection, the temperature that silver is starched reaches the indoor temperature of constant temperature enclosure, so just can guarantee the accuracy of viscosity measurement.This method of testing test condition requires harsh, and efficiency is low, and the frequency of sampling observation is subject to the restriction of detection method, and this detection method directly has influence on the production of silver slurry.
In order to overcome silver-colored slurry viscosity testing process above shortcomings, the applicant develops a kind of silver-colored slurry viscosity Thermostatic detection device, its structure as shown in Figure 1, it comprises constant temperature water tank 1, ebullator 2, refrigeration machine 3, rising pipe 4, return pipe 5 and silver slurry cup 6, ebullator 2 is arranged in constant temperature water tank 1, rising pipe 4 one ends are connected with the water delivering orifice of ebullator 2, the other end and slot type check-out console 11 interlink, return pipe 5 one ends and slot type check-out console ll interlink, the other end leads to constant temperature water tank l, silver slurry cup 6 is placed on slot type check-out console 11, slot type check-out console 11 is positioned at the below of viscosimeter 12.
Because the silver slurry cup that the silver slurry will be housed is placed on slot type check-out console 11, and slot type check-out console l is constantly injected from constant temperature water tank l extraction thermostatted water by ebullator 2, the silver slurry is first carried out the equality of temperature processing by the thermostatted water in slot type check-out console 11, and then carry out viscosity measurement, can guarantee like this accuracy that silver-colored slurry viscosity is measured, can shorten again the constant temperature processing time of silver slurry to be checked, improved detection efficiency, but sample of every detection still needs silver slurry to be checked is carried out to the constant temperature processing, and each sample stationary temperature is processed needs 8～10 minutes.Although more much better than original technology, can't realize the serialization of a plurality of samples to be checked is detected.
Summary of the invention
In order further to optimize the silver-colored slurry viscosity Thermostatic detection device of applicant's development, utilize constant temperature water tank wherein first the silver slurry to be carried out to the constant temperature processing, in silver-colored slurry viscosity testing process, silver through constant temperature processing slurry directly can be carried out to viscosity measurements, the purpose of this invention is to provide a kind of silver-colored paste viscosity detection constant-temperature pretreatment water tank.
