介绍
国际标准化组织 (国际标准化组织) 是国家标准机构的全球联盟 (ISO成员机构). 国际标准的制定通常通过ISO技术委员会进行. 每个对已成立技术委员会的主题感兴趣的成员机构都有权在该委员会中派代表参加. 与 ISO 联络的国际政府和非政府组织也参与了这项工作. ISO 与国际电工委员会密切合作 (国际电工委员会) 关于电气标准化的所有问题.

用于开发本文件的程序以及用于进一步维护的程序在第 1 部分中进行了描述。 1 ISO/IEC 指令的. 尤其, 应注意不同类型ISO文件所需的不同批准标准. 本文件根据 ISO/IEC 指令部分的编辑规则起草 2 (请参阅 iso.org/directives).

This document was prepared by the Technical Committee ISO/TC 206, 精细陶瓷.

1 范围
This document specifies a method for measuring the thixotropic behavior of ceramic pastes using a rotary viscometer. Pastes with high solid loads used in ceramic manufacturing usually have non-Newtonian characteristics. The method is limited to measuring the thixotropic behavior of ceramic slurps with high solid load using “coaxial double-barrel viscometer”, “cone plate viscometer” 和 “parallel plate viscometer” as rotating viscometers.

3 术语和定义
就本文件而言, 以下术语和定义适用.

3.1 剪应力

The force generated when a shear force is applied to a fluid in a plane perpendicular to the shear force

3.2 Shear Rate

The ratio of layer velocity perpendicular to the change in fluid flow

3.3 Newton Attributes

Slurry properties in which shear stress is proportional to shear rate

3.4 Non-Newtonian properties

Slurry characteristic in which shear stress is not proportional to shear rate

3.5 粘度

The ratio of shear stress to shear rate

笔记 1: Ratio is an indication of flow resistance.

3.6 Traffic Curve

A curve showing the relationship between shear rate and shear stress

3.7 触变性

The behavior of a fluid that has a time-dependent flow behavior, so that under controlled shear, the apparent viscosity decreases with time and gradually recovers as the shear force is removed

3.8 Ceramic paste

A suspension of ground ceramic powder mixed or dispersed in water or other liquids

笔记 1: Suspensions are used in ceramic processes such as screen printing, slip casting, tape casting, particle production.
