Foamed silica gel physical property test dataset can be widely applied in material R&D, production control, application verification and other links. During the R&D stage, researchers can use core indicators such as density, compressive stress, tensile strength, elongation at break to conduct performance comparison and trend analysis on samples of different models. Combined with derived fields such as comprehensive performance score and structural stability coefficient, it can provide data support for new material design and formula optimization. In the production process, test environment parameters and batch test results can be used for quality monitoring. Through consistency analysis of indicators such as compression set, water absorption, and hardness, potential deviations can be identified and processes adjusted timely to ensure stable and reliable product performance. In application scenarios, combined with insulation reliability index, thermal conductivity and flame retardant performance grade, the adaptability of the material in typical fields such as sealing gaskets, insulation and heat insulation, automobile shock absorption, electronic buffering, and home appliance parts can be quantitatively evaluated. The comprehensive grade can provide reference for customers to quickly select models. In addition, this dataset can also support performance prediction and intelligent analysis, helping enterprises carry out material reliability research and future model simulation verification, and improve R&D efficiency and service level. The data statistics time period field enables users to conduct historical data review and trend comparison from the time dimension, and the data collection time field further enhances the timeliness analysis and dynamic monitoring capabilities of the data.
1. Data preprocessing: Clean the original test data, eliminate missing values and outliers; Standardize various parameters in accordance with company standards to ensure data meets quality requirements; Perform perturbation or sampling on a small amount of data when necessary to make the overall distribution conform to reality while avoiding leakage of single experiment records.
2. Comprehensive performance score: (1) Standardization treatment: Standardize tensile strength, elongation at break, dielectric strength, and compression set, among which compression set adopts reverse standardization as the smaller the value, the better. (2) Weight setting: Tensile strength 30%, elongation at break 20%, dielectric strength 30%, compression set 20%. (3) Result mapping: Perform weighted summation, then linearly map to the 0-100 score interval and round to the nearest integer as the overall performance score of the sample.
3. Structural stability coefficient: (1) Stability factor calculation: Calculate reversely based on compression set, formula: Stability factor = 1 - (compression set ÷ 5.0), the smaller the value, the more stable the material. (2) Stress retention factor calculation: Normalize 25% compressive stress with the model's standard upper limit, formula: Stress retention factor = 25% compressive stress ÷ upper limit value. (3) Comprehensive calculation: Multiply stability factor by stress retention factor to obtain the structural stability coefficient, which is limited to 0-1 with three decimal places, used to reflect the ability to resist permanent deformation under long-term stress.
4. Insulation reliability index: (1) Dielectric score: Standardize dielectric strength from 2 to 5 kV/mm and convert it to 0-100 points. (2) Volume resistivity score: Full score when ≥1.0×10¹⁴ Ω•cm, otherwise reduce proportionally. (3) Weighted comprehensive: Dielectric score accounts for 60%, volume resistivity accounts for 40%, after weighted average, map to 0-100 and round to the nearest integer as the quantitative indicator of electrical insulation reliability.
5. Comprehensive grade determination: Grade A when comprehensive performance score ≥80, structural stability coefficient ≥0.70, and insulation reliability index ≥80; Grade B when comprehensive performance score ≥60 and at least one of the other two indicators meets the standard; Grade C when comprehensive performance score <60 or none of the three indicators meet the standard.
