粘度是陶瓷泥浆的重要物理性质之一，陶瓷泥浆粘度的测量在工业生产和基础学科研究中具有十分重要的意义。粘度有相对粘度和绝对粘度之分。相对粘度也称条件粘度，包括恩氏粘度，赛氏粘度和雷氏粘度等。粘度是液体内部阻 碍相对流动的一种特性 , 它是液体分子之间、 固体颗粒之间及液体分子与固体颗粒之间产生摩擦的结果。 不同类型的液体有不同的粘度。影响泥浆粘度的因素很多，如原料的矿物组成，颗粒的形状及大小，分散状态，电解质的种类和用量，泥浆的温度，用水量，泥浆的陈腐搅拌及真空处理等都 影响泥浆的性能，从而影响泥浆的粘度。
粘度测量在食品、石油、化妆品和涂料等各行各业中起着非常重要的作用。目前在建筑方面也来越受关注，建筑方面泥浆粘度测量最为重要。所以粘度计的市场也逐年增大，对粘度计的性能、功能和使用体验也提出了一定的要求。
 并且目前正在从更先进的技术方面发展。即利用超声波来完成测量。超声波液体粘度测量与其它测量方法相比 , 以其独有的连续测量特点 , 从5 0 年代起 在许多需要粘度控制的生 产过程中得到越来越广泛的应用。近些年来,人们又试图用它来测 量和连续监视石油钻井泥浆的粘度 , 现场使用后发现,对于石油泥浆 , 超声粘度计几乎完全不 能准确有效地工作。 最新分析研究〔1〕指出, 现有超 声粘度计都是利用液体对振子的切变阻抗来测量粘度 , 而这种切变声阻抗方法只 限于纯牛顿液体 , 对石油泥浆等非纯 牛顿液体不适用。

Abstract
Viscosity is one of the important physical properties of ceramic mud, and the measurement of ceramic mud viscosity is very important in industrial production and basic study. Viscosity has a relative viscosity and absolute viscosity.Viscosity has a relative viscosity and absolute viscosity.Relative viscosity is also called conditional viscosity, including the viscosity of the n, the viscosity of the saybolt and the viscosity of the redwood. Viscosity is a feature inside the liquid resistance in relative flow, it is between liquid molecules, solid particles and the friction between solid particles and liquid molecules.Different types of liquids have different viscosity. There are many factors affecting the slurry viscosity, such as the mineral composition of raw material, shape and size of particles, decentralized state, the variety and dosage of electrolyte, the temperature of mud, water, mud stale mixing and vacuum treatment and so on all affect the performance of the slurry, which influence the viscosity of the mud.
Viscosity measurement plays an important role in food, oil, cosmetics and coatings. The more attention is being paid to the construction, the most important is the mud viscosity measurement. Therefore, the market of viscosimeter increases with each other, and the performance, functions, and usage experience of the viscosimeter are also required.
And it's evolving from more advanced technologies. That means using ultrasound to do the measurement. Ultrasonic liquid viscosity compared with other measurement methods, with its unique characteristics of continuous measurement, since 5 s In many of the need of viscosity control is more and more extensive application in the production process. In recent years, people and try to use it to measure and continuous monitoring of oil drilling mud viscosity, found that after field use for oil slurry, ultrasonic viscometer almost nothing can work accurately and effectively. Latest study [1] points out that the existing ultra sound viscometer is using liquid shear impedance to measure the viscosity of vibrator, which cut voice impedance method is only limited to pure Newtonian liquid, for oil slurry, etc. Not pure is not applicable to Newtonian fluid.
