硫酸法钛白水解工艺制得的偏钛酸的关键数据
收藏资源简介:
1.数据清洗与预处理规则: 对原始实验数据进行清洗,剔除异常值;标准化不同实验批次的数据格式(如浓度单位、粒径测量方法统一)。 2.分级算法与逻辑: 三级水力旋流分离规则: 一级分离:输入浆料分离为粗颗粒A(1.7-2.1 μm)和细颗粒E(0.6-1.7 μm); 二级分离:细颗粒E分离为B(1.4-1.7 μm)和F(0.6-1.4 μm); 三级分离:细颗粒F分离为C(1.0-1.4 μm)和D(0.6-1.0 μm)。 分级决策依据: 粒径阈值动态调整算法,结合浆料浓度(250-400 g/L)优化分离参数。 3.性能指标计算模型: TCS(遮盖力指标):基于钛白粉粒径与光学性能公式推导,结合实验数据拟合; SCX(分散性指数):通过粒径分布与分散测试数据构建回归模型; Jasn(白度系数):采用行业标准公式与实测光谱反射率计算。 4.数据关联规则: 浆料浓度与分级产率关联模型:利用线性回归或机器学习算法,预测不同浓度下的各级颗粒产率; 粒径-性能映射规则:建立粒径区间与颜料性能指标(TCS、SCX、Jasn)的对应关系表,指导产品分级应用。
1. Data Cleaning and Preprocessing Rules: Clean the raw experimental data and eliminate outliers; standardize the data formats of different experimental batches (e.g., unify concentration units and particle size measurement methods). 2. Hierarchical Algorithm and Logic: Three-stage hydrocyclone separation rules: Primary separation: Separate the input slurry into coarse particles A (1.7-2.1 μm) and fine particles E (0.6-1.7 μm); Secondary separation: Separate fine particles E into particles B (1.4-1.7 μm) and F (0.6-1.4 μm); Tertiary separation: Separate fine particles F into particles C (1.0-1.4 μm) and D (0.6-1.0 μm). Grading decision basis: Dynamic adjustment algorithm for particle size thresholds, which optimizes separation parameters combined with slurry concentration (250-400 g/L). 3. Performance Index Calculation Models: TCS (covering power index): Derived from the formula relating titanium dioxide particle size and optical properties, fitted with experimental data; SCX (dispersion index): Constructed a regression model using particle size distribution and dispersion test data; Jasn (whiteness coefficient): Calculated using industry-standard formulas and measured spectral reflectance. 4. Data Association Rules: Slurry concentration and grading yield association model: Use linear regression or machine learning algorithms to predict the yield of particles at each stage under different concentrations; Particle size-performance mapping rules: Establish a corresponding relationship table between particle size intervals and pigment performance indicators (TCS, SCX, Jasn) to guide product grading applications.
