在制漆及塗漆的过程中,常需测定粘度以控制漆及漆膜的质量,特別是熬制各种油基酚醛清漆时,必須正确掌握熬漆时分子的聚合过程,才能保証质量及塗漆工艺的順利进行。因熬漆将到終点时粘度变化甚快,常在数分钟內,使漆的聚合程度迅速增加,因之一般測定粘度的方法甚难满足生产的需要,最近各国虽設計有不少自动和快速測定粘度的仪器,但均不易制造或购得,有的結构复杂容易損坏,不便車間使用,故我国目前大多数厂都凭經驗来掌握熬漆 In the process of making paints and lacquers, it is often necessary to measure the viscosity to control the quality of lacquers and lacquers. In particular, when boiling all kinds of oil-based novolaks, the polymerization process of lacquer must be correctly grasped to ensure the quality and Paint the smooth progress of the process. Due to paint to the end of the viscosity changes rapidly, often within minutes, the degree of polymerization of the rapid increase in the paint, so the general method of measuring viscosity is difficult to meet the production needs, although many countries have recently designed a lot of automatic and fast Determination of viscosity of the instrument, but are not easy to manufacture or purchase, and some complex structure easily damaged, not easy to use the workshop, so most factories in our country now have experience to master paint
