1. 精准调控材料疏水性能：公司可通过分析不同硬段/软段比例对侧石吸水率的影响，优化分子结构设计，在保证材料机械性能的同时显著降低其吸水率，提高产品在潮湿环境中的尺寸稳定性和耐久性。
2. 推动智能疏水材料研发：本数据可为高分子材料设计领域的研究机构提供支撑，助力其探索微相分离结构对水分传输行为的调控机制，为开发具有环境响应性的低吸水率环保建材提供理论指导。1.数据采集：实时记录不同聚氨酯基体硬段/软段比例下的环保柔性装配式侧石吸水率测试数据，包括测试样品编号、测试时间、聚氨酯基体硬段/软段比例、吸水率/%等字段。
2.数据预处理：（1）对采集的数据进行去噪处理，确保数据准确性。（2）将历史采集的数据（包含本次采集）进行聚合，形成数据集X，并针对数据集X中的吸水率字段，计算出其平均值。
3.计算线性回归斜率a和截距b:基于数据集X（以聚氨酯基体硬段/软段比例为自变量、吸水率为因变量），运用SLOPE函数，基于最小二乘法原理确定斜率a，运用INTERCEPT函数确定截距b。斜率a表示单位聚氨酯基体硬段/软段比例变化对环保柔性装配式侧石吸水率的影响程度，截距b表示基准聚氨酯基体硬段/软段比例下环保柔性装配式侧石的吸水率值。
4.结果运用：（1）计算比例系数k：k=|a/吸水率平均值|×100%；（2）若k≥10%，则判定为“高影响”，若5%≤k＜10%，则判定为“中影响”，若k＜5%，则判定为“低影响”。

This dataset focuses on analyzing the impact of the hard segment/soft segment ratio of polyurethane matrix on the water absorption rate of environmentally friendly flexible assembled curb stones, and reveals the quantitative relationship between molecular segment ratio, material hydrophilicity, microphase separation degree and water diffusion path. It provides critical decision-making basis for the company (as a manufacturer) and external stakeholders, holding significant application value, which is specifically reflected in the following aspects:
1. Precise regulation of material hydrophobic properties: The company can analyze the impact of different hard/soft segment ratios on the water absorption rate of curb stones, optimize molecular structure design, significantly reduce water absorption while ensuring the mechanical properties of the material, and improve the dimensional stability and durability of products in humid environments.
2. Promote the research and development of intelligent hydrophobic materials: This dataset can provide support for research institutions in the field of polymer material design, help them explore the regulation mechanism of microphase separation structure on water transport behavior, and provide theoretical guidance for the development of environmentally responsive low water absorption environmentally friendly building materials.
1. Data Collection: Real-time recording of water absorption rate test data of environmentally friendly flexible assembled curb stones under different hard segment/soft segment ratios of polyurethane matrix, including fields such as test sample number, test time, hard segment/soft segment ratio of polyurethane matrix, water absorption rate / %, etc.
2. Data Preprocessing: (1) Denoise the collected data to ensure data accuracy. (2) Aggregate the historically collected data (including this collection) to form dataset X, and calculate the average value of the water absorption rate field in dataset X.
3. Calculation of linear regression slope a and intercept b: Based on dataset X (with the hard segment/soft segment ratio of polyurethane matrix as the independent variable and water absorption rate as the dependent variable), use the SLOPE function to determine the slope a based on the principle of least squares, and use the INTERCEPT function to determine the intercept b. Slope a represents the degree of impact of a unit change in the hard segment/soft segment ratio of polyurethane matrix on the water absorption rate of environmentally friendly flexible assembled curb stones, and intercept b represents the water absorption rate value of environmentally friendly flexible assembled curb stones under the reference hard segment/soft segment ratio of polyurethane matrix.
4. Result Application: (1) Calculate the proportional coefficient k: k = |a / average water absorption rate| × 100%; (2) If k ≥ 10%, it is judged as "high impact"; if 5% ≤ k < 10%, it is judged as "medium impact"; if k < 5%, it is judged as "low impact".
