传统检验生漆水分的方法是采用煎盘秤,称取去渣生漆10分,然后在酒精灯上煎去水分,即得生漆的水分含量——几分几厘几毫,也可以换算成百分率表示。现代检验生漆水分是采用烘箱法,即用天平称过生漆重量之后,放在烘箱内,调温到105℃,蒸发其水分至恒重再次称重,可求得生漆的含水量。用上述两法检验生漆的水分,作者经过多次对比试验后发现烘箱法所测的含水率比煎盘法大约多2%。分析其原因,可能是煎
The traditional method for testing lacquer moisture is to use a fry pan scale. Weigh the scum lacquer 10 minutes. Then we fry the water on the alcohol lamp. The water content of the lacquer is a few centimeters. It can also be converted into percentages. . Modern inspection lacquer moisture is the use of the oven method, that is, after using the scale to weigh the lacquer, placed in an oven, thermostat to 105 °C, evaporate the water to a constant weight and weigh again, you can obtain raw lacquer moisture content. The above two methods were used to test the water content of the lacquer. After several comparison tests, the authors found that the moisture content measured by the oven method was about 2% higher than the frying method. Analysis of the reason may be fried
