Description

Technical Field

[0001] The present invention relates to the technical field of ceramic slurry viscosity data analysis, and in particular to a system and method for analyzing ceramic slurry viscosity data after degassing based on sampling testing. Background Art

[0002] With the continuous advancement of modern manufacturing, the application of ceramic materials in the fields of electronics, aviation and biomedical high technology is increasing. Ceramic slurry is the basis for the preparation of these materials, and its performance directly affects the quality of the final product. Degassing of ceramic slurry is one of the key steps to ensure its performance, and viscosity control after degassing is the core parameter that determines the application performance of the slurry.

[0003] However, traditional degassing and viscosity testing methods have many limitations. First, in order to achieve the specified viscosity requirements during the production of ceramic slurry, the traditional process requires degassing in a vacuum environment. During the entire process, multiple manual sampling tests are required to ensure that the viscosity of the slurry meets the process requirements. This frequent sampling test is not only time-consuming and labor-intensive, but also affects product quality and production efficiency due to frequent sampling. Secondly, it is inconvenient to use a viscometer to confirm the viscosity of the ceramic slurry in the degassing tank during the production process. Each sampling requires pausing the degassing and restoring from the vacuum state to normal pressure. In addition, each sampling causes product crusting and slurry waste, and cleaning the sample port will also cause contamination. Summary of the Invention

[0004] The object of the present invention is to provide a system and method for analyzing the viscosity data of ceramic slurry after degassing based on sampling testing, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a ceramic slurry post-degassing viscosity data analysis system based on sampling testing, the system comprising: a slurry parameter acquisition module, a curve chart module, a data management module and a feedback and control module, the slurry parameter acquisition module is used to obtain the solvent loss through the mass change of the degassing tank, and obtain the viscosity, solid content and density data of the ceramic slurry through the sensor, the data management model is responsible for storing and managing all collected data, the curve chart module performs fitting calculations between viscosity, solid content, density and solvent loss based on the collected data, generates a corresponding curve chart, and predicts and analyzes the slurry parameters, and the feedback and control module issues an early warning when the viscosity, solid content or density exceeds the normal range during the ceramic slurry degassing process by setting thresholds and real-time monitoring.

[0006] Furthermore, the slurry parameter acquisition module includes a viscosity acquisition unit, a solid content acquisition unit, a density acquisition unit and a solvent loss acquisition unit. After the slurry degassing starts, the degassing tank is weighed as a whole and the values ​​are recorded every 10 minutes, and the solvent loss is calculated. At the same time, samples are taken for viscosity testing, solid content testing and density testing to obtain the slurry viscosity, solid content and density.

[0007] Furthermore, the slurry is preferably composed of ceramic powder, a binder, a dispersant, and an organic solvent; the ceramic powder includes one or more of aluminum oxide, silicon nitride, magnesium oxide, and yttrium oxide; the binder is preferably polyvinyl butyral; the dispersant includes one or more of fish oil and castor oil; and the organic solvent includes one or more of isopropyl alcohol, n-butanol, ethyl acetate, and butyl acetate. Based on the total mass of the ceramic powder, the mass percentages of the ceramic powder, binder, and dispersant are preferably 92%-95%, 10%-16%, and 1%-3%, respectively. The mass percentage of the organic solvent in the ceramic slurry is preferably 65%-85%.

[0008] Furthermore, the graph module includes a graph drawing unit and an analysis graph unit. The graph drawing unit calculates according to the amount of solvent loss at the end of each degassing cycle, with the amount of solvent loss as the horizontal coordinate and the slurry viscosity, slurry solid content and slurry density at the end of each degassing cycle as the vertical coordinate. The linear fitting obtains the fitting curves of solvent loss-slurry viscosity, solvent loss-slurry solid content and solvent loss-slurry density. The analysis graph unit is used to obtain the viscosity, solid content and density of the slurry during the degassing process according to the fitting curve when the pulping process and the degassing process have not changed. The preparation method of the ceramic slurry preferably includes the following steps: first, stirring and mixing the binder with part of the organic solvent to obtain a uniform glue solution; secondly, ball-milling the remaining organic solvent with the ceramic powder and dispersant to obtain a mixed solution; finally, ball-milling the mixed solution with the glue solution to obtain the ceramic slurry. The preferred conditions are: the ball milling mixing speed is preferably 50-60r / mi n; The ceramic powder dispersion ball milling time is preferably 120-180min. After the glue solution and the mixed solution are ball milled, they are filtered using a filter screen; and the mesh number of the screen is preferably 200 mesh. The specific execution steps of the slurry process and degassing process are as follows: Step 1: weigh the empty tank of the 30°C constant temperature degassing tank and record it; Step 2: weigh the slurry loaded in the 30°C constant temperature degassing tank, and take samples to test the initial viscosity, initial solid content, and initial slurry density; Step 3: weigh the empty tank of the 30°C constant temperature degassing tank every 10 minutes during the degassing process Weigh once and take samples to test viscosity, solid content and slurry density; Step 4: 30℃ constant temperature degassing tank, after degassing, weigh and take samples to test final viscosity, solid content and density; Step 5: Record and complete steps 1 to 4 for more than 3 times, and draw the curve in Origin; Step 6: Get the functional relationship between weight and viscosity, solid content and density during the degassing process in the degassing tank by fitting the curve; Step 7: 30℃ constant temperature degassing tank, calculate the viscosity value at the end of degassing by weight change for verification.

[0009] Furthermore, the feedback and accusation module includes a threshold setting unit and an early warning unit. The threshold setting unit determines the normal range of viscosity, solid content and density of the ceramic slurry based on production requirements and combined with process standards. The early warning unit calculates the viscosity, solid content and density of the slurry during the degassing process by fitting the curve, and compares them with the range of the threshold setting unit in real time. When it is detected that the viscosity, solid content or density exceeds the set range, the system triggers an early warning.

[0010] A method for analyzing viscosity data of ceramic slurry after degassing based on sampling test includes the following steps:

[0011] S1: Take the ceramic slurry produced in batch Q as the standard sample, weigh the mass of the empty degassing tank before the ceramic slurry is transferred into the degassing tank, and weigh the entire weight after the ceramic slurry is transferred into the degassing tank, so as to calculate the mass of the slurry added to the degassing tank; take samples to test the initial viscosity, initial slurry solid content and initial slurry density of the slurry, where Q represents the batch of ceramic slurry produced, and the sampling weight is negligible compared to the total slurry mass;

[0012] S2: After the slurry degassing begins, the entire degassing tank is weighed and the values ​​are recorded at the set time intervals. At the same time, samples are taken for viscosity test, solid content test and density test. The above operation is repeated until the degassing is completed;

[0013] S3: Calculate the solvent loss at the end of each degassing cycle, use the solvent loss as the horizontal coordinate, and the slurry viscosity, slurry solid content and slurry density at the end of each degassing cycle as the vertical coordinate to obtain the solvent loss-slurry viscosity, solvent loss-slurry solid content and solvent loss-slurry density fitting curves.

[0014] Furthermore, in step S2: the set of slurry viscosities output by different sensors is obtained as {η1, η2, ..., η n}, the slurry solid content data set is {C1,C2,...,C n}, the slurry density data set is {ρ1,ρ2,...,ρ n}, the solvent loss data set is {W1,W2,...,W n}, where η1 represents the initial viscosity obtained, η n represents the obtained nth slurry viscosity, C1 represents the obtained initial slurry solid content, C n represents the solid content of the nth slurry obtained, ρ1 represents the initial slurry density obtained, ρ n Indicates the obtained nth slurry density, W1 indicates that the degassing tank is weighed and recorded as a whole according to the set time interval, and the first solvent loss is calculated, W n It represents the calculated nth solvent loss, and n represents the number of data recorded at the specified time interval. By testing the viscosity, solid content, density and solvent loss of the slurry, we can fully understand the changes in the physical properties of the slurry during the degassing process.

[0015] Furthermore, in step S3: the calculation formula of the fitting function between the solvent loss and the slurry viscosity is as follows:

[0016]

[0017] Among them, W i represents the solvent loss amount obtained for the i-th time, W avgrepresents the average value of solvent loss, α1 represents the fitting parameter, and β1 represents the weighting coefficient, which is used to reflect the nonlinear degree of the change of slurry viscosity with solvent loss;

[0018] The calculation formula of the solvent loss-slurry solid content fitting function is as follows:

[0019]

[0020] Among them, α2 controls the amplitude of solid content growth and determines the rising rate of the curve, λ controls the response speed of solvent loss to solid content, β2 is used to adjust the nonlinear relationship between solid content and solvent loss, and γ represents the high-order effect of solvent loss on solid content change.

[0021] The calculation formula of the solvent loss-slurry density fitting function is as follows:

[0022] ρ(W i )=ρ1+α3*W+β3*W 2 +k*W 3 ;

[0023] Among them, α3 represents the initial change rate of density with solvent loss, β3 represents the nonlinear change trend of density with solvent loss, and k is the fitting coefficient, which represents the change amplitude of density in the fitting curve. Through the fitting function, the viscosity, solid content and density of the slurry can be calculated and analyzed according to different solvent loss amounts, thereby realizing real-time control of product quality.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. After linear fitting of slurry data analysis, there is no need to perform viscosity / solid content testing for subsequent slurry production.

[0026] 2. Product quality assurance, avoid contact with air, avoid residual slurry at the interface to cause retention of micron-sized particles, maximize slurry flow rate, and avoid waste in testing.
