聚乙烯板材拉伸强度数据
收藏资源简介：
聚乙烯板材拉伸强度是聚乙烯板材最大均匀塑性变形的应力，是重要质量指标之一。统计公司内部质检部门对不同型号聚乙烯板材的拉伸强度检测数据，分析该数据与产品标准值之间的差别，得到评级指数，通过评级指数对该型号的聚乙烯板材进行质量评级，以确保产品的质量。1.数据统计：汇总公司质检部门提供的各型号聚乙烯板材拉伸强度测量值，明确聚乙烯板材拉伸强度标准值。2.数据处理：通过每种型号聚乙烯板材取样测量值，计算得到平均拉伸强度值；再通过（平均拉伸强度值-拉伸强度标准值）/拉伸强度标准值，计算得到该型号聚乙烯板材的评级指数，最后通过评级指数得到该型号聚乙烯板材的评级。其中，评级A为评级指数≥0.3，评级B为0.3＞评级指数≥0.15，评级C为0.15＞评级指数≥0，评级D为0＞评级指数。3.数据应用：公司可以借助每种型号的聚乙烯板材拉伸强度的评级，直观了解该批次产品的拉伸强度质量情况，以保证产品质量稳定。
Tensile strength of polyethylene sheets refers to the stress at their maximum uniform plastic deformation, and is one of the key quality indicators. This dataset is developed based on the tensile strength test data of various polyethylene sheet models collected by the company's internal quality inspection department. By analyzing the deviation between the measured data and the product standard values, a rating index is calculated, which is then used to conduct quality ratings for each polyethylene sheet model to ensure product quality. The dataset construction includes three main parts: 1. Data Statistics: Collect and aggregate the measured tensile strength values of each polyethylene sheet model provided by the company's quality inspection department, and confirm the standard tensile strength values for polyethylene sheets. 2. Data Processing: For each polyethylene sheet model, compute the average tensile strength value based on the sampled measured data; then calculate the rating index of the model using the formula: (average tensile strength value - standard tensile strength value) / standard tensile strength value. Finally, assign a quality rating to the polyethylene sheet model according to the rating index, with the following rating criteria: - Rating A: rating index ≥ 0.3 - Rating B: 0.3 > rating index ≥ 0.15 - Rating C: 0.15 > rating index ≥ 0 - Rating D: rating index < 0 3. Data Application: The company can intuitively grasp the tensile strength quality of each product batch by using the ratings of the tensile strength of each polyethylene sheet model, thereby ensuring stable product quality.
