汽車涂料粘度固含控制參考數(shù)據(jù)

汽車涂料的粘度及固含控制線建議清漆及純閃銀漆，粘度控制在±10?15秒，固含控制在±2?3%研磨色漆粘度控制在±20?30秒，固含控制在±3?4%均值粘度低，控制線走下線，均值粘度高，控制線走上線，如果產(chǎn)量小，則加上人為秤量誤差源。統(tǒng)計計算數(shù)據(jù)如下：樣本1：哈飛的產(chǎn)品292-9903，每機產(chǎn)品的數(shù)量是2600KG,由于秤量的數(shù)量大，秤量誤差可以忽略不計，該粘度及固含變差主要來源是材料（樹脂）之間的誤差粘度數(shù)據(jù)：46.446.344.247.052.449.841.845.845.643.551.248.047.645.046.845.642.549.148.744.843.943.542.444.643.346.549.246.846.842.643.739.539.751.651.946.645.447.349.344.443.049.143.642.245.141.240.245.949.946.647.639.246.847.343.444.547.646.147.852.143.251.845.344.645.142.641.843.040.043.339.941.240.646.641.343.639.336.739.337.739.639.238.141.547.750.045.743.746.650.150.343.649.649.643.743.947.146.243.843.947.561.641.242.845.642.045.846.940.644.547.846.645.043.845.248.842.850.846.647.242.041.741.744.142.4292-9903粘度正態(tài)分布圖:C7的直方圖C7均值為45.09秒標準差3.711秒按照3個標準差控制，粘度的控制線為45.09±11.13秒C7C7均值為45.09秒標準差3.711秒按照3個標準差控制，粘度的控制線為45.09±11.13秒C7的I-MR控制圖UCL=53.66X=45.091132537496"738597109121UCL=10.52MR=3.2211325374961738597109121固含數(shù)據(jù):
