汽车涂料粘度固含控制参考数据.doc

汽车涂料的粘度及固含控制线建议1.清漆及纯闪银漆，粘度控制在1015秒，固含控制在232.研磨色漆粘度控制在2030秒，固含控制在343.均值粘度低，控制线走下线，均值粘度高，控制线走上线，4.如果产量小，则加上人为秤量误差源。统计计算数据如下：样本1：哈飞的产品292-9903，每机产品的数量是2600KG,由于秤量的数量大，秤量误差可以忽略不计，该粘度及固含变差主要来源是材料（树脂）之间的误差粘度数据：46.4 46.344.2 47.052.4 49.841.8 45.845.6 43.551.2 48.047.6 45.0 46.845.6 42.549.1 48.744.8 43.943.5 42.444.6 43.346.549.2 46.846.8 42.643.7 39.539.7 51.651.9 46.645.4 47.349.344.4 43.049.1 43.642.2 45.141.2 40.245.9 49.946.6 47.639.246.8 47.343.4 44.547.6 46.147.8 52.143.2 51.845.3 44.645.142.6 41.843.0 40.043.3 39.941.2 40.646.6 41.343.6 39.336.739.3 37.739.6 39.238.1 41.547.7 50.045.7 43.746.6 50.150.343.6 49.649.6 43.743.9 47.146.2 43.843.9 47.561.6 41.242.845.6 42.045.8 46.940.6 44.547.8 46.645.0 43.845.2 48.842.850.8 46.647.2 42.041.7 41.744.1 42.4292-9903粘度正态分布图：均值为45.09秒标准差3.711秒按照3个标准差控制，粘度的控制线为45.0911.13秒固含数据：32.30 32.29 33.86 33.19 33.72 32.07 32.22 32.22 32.56 32.93 33.78 33.66 33.90 33.53 33.53 33.54 32.49 33.07 33.99 33.04 33.23 34.30 34.30 32.77 33.61 31.87 32.42 32.28 32.75 32.44 32.28 32.65 32.93 33.70 33.51 31.57 32.18 32.17 32.31 32.93 32.20 32.86 33.12 32.18 33.01 32.50 32.61 31.88 32.59 33.34 32.69 33.50 32.38 32.24 32.86 33.73 33.32 31.80 31.41 33.18 32.02 32.60 32.75 34.74 33.91 33.05 33.02 31.64 31.87 32.15 32.00 32.58 32.27 30.78 32.62 29.34 32.33 32.28 32.46 32.99 33.60 33.68 32.83 33.42 33.03 31.25 32.43 33.10 32.03 32.86 32.65 32.96 32.91 33.03 31.03 30.91 33.06 33.18 32.08 32.39 32.66 33.04 32.51 32.71 32.72 33.34 32.71 31.97 32.49 32.57 33.93 31.88 32.90 32.08 31.49 30.59 32.36 32.99 32.80 32.36 32.29 32.15 32.56 33.29 32.61292-9903固含的正态分布图均值为32.67标准差0.789按照3个标准差控制，固含的控制线为32.672.37说明：因为考虑树脂的粘度及固含的变化，影响产品的控制范围：粘度在11.13秒，固含在2.37样本2：哈飞的产品921-0513高温白色漆，每机产品2600KG，该由于秤量的数量大，秤量误差可以忽略不计，该粘度及固含变差主要来源是材料（树脂、油种、粉料的吸油量不同、研磨损耗）之间的误差。粘度数据70.2 70.6 92.4 66.8 61.8 62.4 78.4 79.4 68.2 67.5 78.864.9 60.2 61.9 61.7 62.9 62.9 65.9 71.3 67.9 62.3 65.485.5 75.7 78.6 89.4 57.1 64.7 76.9 95.2 87.4 79.2 73.872.5 72.1粘度粘度正态分布图均值为71.77秒标准差9.778秒按照3个标准差控制，粘度的控制线为71.7721.35秒固含数据65.23 65.86 68.82 67.72 65.70 68.27 65.60 67.39 69.82 64.35 64.93 63.04 65.06 65.88 66.02 66.06 64.62 64.0964.15 67.40 66.00 67.16 68.63 66.06 66.66 65.90 68.7765.86 65.73 65.35 65.87 66.47 66.31
