.刮速、油墨粘度、刮刀角度与涂层膜厚的研究摘要：对同一款产品在不同的刮速、刮刀角度下使用不同粘度的油墨在网版上进行印刷。探究刮速、油墨粘度、刮刀角度与涂层厚度的联系关键词：刮速；油墨粘度；刮刀角度；涂层膜厚；产品颜色涂层膜厚对于产品颜色有着重要影响，因此研究影响涂层膜厚的因素对于有效地控制产品颜色及制定参数标准化至关重要。在出现批量色差问题时，能够找到有效地措施及时控制产品质量。影响涂层膜厚的因素有很多，此次实验重点研究刮速、油墨粘度、刮刀角度对于涂层膜厚的影响1.实验1.1实验条件，材料及仪器设备地点：印刷线；材料：超白玻、产品各度油墨、洗网水、稀释剂；仪器设备：印刷机、网版、调墨刀、螺旋测微仪。1.2实验内容1.2.1刮刀角度对产品膜厚的影响：保持刮刀速度和油墨粘度不变，调整刮刀角度分别为60度，70度和80度进行印刷，产品烘干后对膜厚进行测量得到的数据见表（1）。产品型号测定参数角度607080A总膜厚0.07850.07350.08B总膜厚0.0520.0510.053C总膜厚0.02850.0310.0315D总膜厚0.0510.0410.038从上面图表分析得出两个结论1. 玻璃不是完全的平面，玻璃不同的点上的涂层厚度是不一样的。由于取点问题，上述的试验未能达到预期效果，得到刮刀角度和涂层厚度的关系。需重新试验。2. 不同颜色的产品膜厚是不一样的，一般白色的膜厚要大，从产品出炉的颜色来看，白色产品受刮刀角度影响较明显；红、银和黑几乎看不到颜色的变化。1.2.2优雅曲线产品刮刀角度与涂层厚度的关系研究为了进一步验证刮刀角度与涂层厚度的关系，我们选取受参数影响较大的白色产品进行试验，在印刷前对需测量点的位置做上标记，每片玻璃选取不同位置的4点，每个角度使用9片玻璃进行试验，试验数据如下表：角度序号原板印光油后印面漆后封底后光油膜厚面漆膜厚封底膜厚60A113.1383.1643.1853.210.0260.0210.02523.1653.1893.2123.2410.0240.0230.02933.1393.1643.1873.2140.0250.0230.02743.1583.1853.2243.260.0270.0390.036平均值0.02550.02650.02925A213.163.1753.23.2240.0150.0250.02423.1463.1653.193.220.0190.0250.0333.1583.1713.1973.230.0130.0260.03343.1413.173.2173.2590.0290.0470.042平均值0.0190.030750.03225A313.163.1753.23.2230.0150.0250.02323.1483.1683.1893.220.020.0210.03133.1593.1753.23.2310.0160.0250.03143.1413.173.2053.240.0290.0350.035平均值0.020.02650.03A413.1593.1713.23.2240.0120.0290.02423.1423.1613.1893.220.0190.0280.03133.163.1753.23.230.0150.0250.0343.1423.173.2063.2410.0280.0360.035平均值0.01850.02950.03A513.1483.1683.1913.220.020.0230.02923.1323.1553.1813.2120.0230.0260.03133.1513.173.1923.2250.0190.0220.03343.1363.163.23.240.0240.040.04平均值0.02150.027750.03325A613.1583.1783.23.2280.020.0220.02823.1343.1533.183.210.0190.0270.0333.1553.1753.2013.230.020.0260.02943.1353.163.1973.240.0250.0370.043平均值0.0210.0280.0325A713.1523.1713.1923.220.0190.0210.02823.143.1633.1893.2190.0230.0260.0333.1563.173.1933.230.0140.0230.03743.1363.1663.2053.240.030.0390.035平均值0.02150.027250.0325A813.1483.1653.193.2140.0170.0250.02423.1533.1753.1993.230.0220.0240.03133.1463.1623.1893.2190.0160.0270.0343.1553.183.2253.2650.0250.0450.04平均值0.020.030250.03125A913.143.163.183.2120.020.020.03223.163.1893.2093.240.0290.020.03133.1393.1583.1843.210.0190.0260.02643.1583.1853.2223.2560.0270.0370.034平均值0.023750.025750.0307560平均膜厚0.0211940.0280280.031306B213.1383.1583.1853.2070.020.0270.02223.1413.1593.183.2090.0180.0210.02933.163.1823.2083.2440.0220.0260.03643.1573.183.2023.240.0230.0220.038平均值0.020750.0240.03125B313.1373.1583.1863.2040.0210.0280.01823.1253.1483.173.20.0230.0220.0333.1363.1543.183.210.0180.0260.0343.1213.1453.173.1920.0240.0250.022平均值0.02150.025250.025B413.1363.1593.183.2070.0230.0210.02723.1343.1593.173.1980.0250.0110.02833.1393.1553.183.2060.0160.0250.02643.1263.1473.1723.1940.0210.0250.022平均值0.021250.02050.02575B513.143.1613.1873.2120.0210.0260.02523.1423.163.183.2110.0180.020.03133.1653.183.2053.2370.0150.0250.03243.163.183.213.2360.020.030.026平均值0.01850.025250.0285B613.1583.1763.23.2250.0180.0240.02523.1533.1753.1983.2250.0220.0230.02733.1433.163.1873.2190.0170.0270.03243.1393.163.1873.2150.0210.0270.028平均值0.01950.025250.028B813.1543.1753.2113.240.0210.0360.02923.1573.1743.23.230.0170.0260.0333.1453.1723.1983.230.0270.0260.03243.1423.1653.193.2250.0230.0250.035平均值0.0220.028250.0315B913.1453.173.1973.2150.0250.0270.01823.1413.163.183.2020.0190.020.02233.1643.193.213.240.0260.020.0343.1643.1793.213.2390.0150.0310.029平均值0.021250.02450.0247570平均膜厚0.0206790.0247140.02782180C113.1623.183.1893.2190.0180.0090.0323.1383.1593.173.20.0210.0110.0333.1583.183.1953.2260.0220.0150.03143.143.1593.173.20.0190.0110.03平均值0.020.01150.03025C213.1683.1843.2023.2280.0160.0180.02623.1473.163.183.2010.0130.020.02133.1673.1853.23.2270.0180.0150.02743.1423.163.183.20.0180.020.02平均值0.016250.018250.0235C313.1683.1853.2043.2280.0170.0190.02423.1463.163.1813.2050.0140.0210.02433.1663.1843.213.230.0180.0260.0243.1473.163.1793.2040.0130.0190.025平均值0.01550.021250.02325C413.163.1733.1983.2180.0130.0250.0223.1433.1613.183.2090.0180.0190.02933.1593.1733.1973.230.0140.0240.03343.1473.1673.1853.2090.020.0180.024平均值0.016250.02150.0265C513.1553.1753.1983.2180.020.0230.0223.1483.163.1813.210.0120.0210.02933.1593.1743.1983.230.0150.0240.03243.1443.173.1893.2150.0260.0190.026平均值0.018250.021750.02675C613.153.1683.193.2160.0180.0220.02623.1593.1753.1993.2160.0160.0240.01733.1483.163.183.2090.0120.020.02943.163.1763.1963.2180.0160.020.022平均值0.01550.02150.0235C713.163.1733.1983.2180.0130.0250.0223.1483.1653.1863.210.0170.0210.02433.163.1733.1973.2180.0130.0240.02143.1493.1633.1873.210.0140.0240.023平均值0.014250.02350.022C813.153.1663.1873.210.0160.0210.02323.1593.1743.1933.220.0150.0190.02733.1483.1663.1883.2130.0180.0220.02543.1583.1793.1983.2180.0210.0190.02平均值0.01750.020250.02375C913.1463.1623.1833.2070.0160.0210.02423.1713.1933.2083.2290.0220.0150.02133.1483.1643.1863.2140.0160.0220.02843.1623.1863.213.2340.0240.0240.024平均值0.01950.02050.0242580平均膜厚0.0170.020.024861从上面图表分析得出结论产品涂层厚度随刮刀角度的增大而减小，参数变更对产品出炉后的颜色影响较大。光油膜厚面漆膜厚封底膜厚600.0211940.0280280.031306700.0206790.0247140.027821800.0170.020.024861从表中数据可以计算出，如刮刀由60调整为80，光油膜厚减少19.8%，面漆膜厚减少28.6%，封底膜厚减少20.6%1.2.3刮刀速度对产品膜厚的影响：保持刮刀角度和油墨粘度不变，调整刮刀速度分别为15，20和25进行印刷，产品烘干后对膜厚进行测量得到的数据见表产品型号测定参数速度152025优雅曲线总膜厚0.0720.07250.0705晶钻红总膜厚0.06750.06650.0615银色紫丁香总膜厚0.0323333330.0316666670.031333333横纹黑总膜厚0.04350.04250.0426从上面图表分析得出结论产品涂层厚度随刮刀速度的变化不明显，参数变更对产品出炉后的颜色影响不大。1.2.4油墨粘度对产品膜厚的影响：保持刮刀角度和刮刀速度不变，利用稀释剂调整油墨粘度进行印刷，产品烘干后对膜厚进行测量得到的数据见表产品型号测定参数粘度A面漆膜厚1500220033000.003333330.0063333330.010666667B面漆膜厚2300300035000.04350.04650.047C面漆膜厚2000250030000.0240.0280.028333333从上面数据分析得出结论产品涂层厚度随油墨粘度的增大而增大，参数变更对产品出炉后的颜色
