Problems solved by technology

[0003] However, the above methods have one or more of the following problems to varying degrees: ①The suspension needs to be left for a long time to know its suspension performance; ②It can only be measured qualitatively, and the test error is large in quantitative measurement; When the liquid has no obvious stratification or the stratification takes a long time, and when the suspension is colored and the container is opaque and the stratification cannot be observed, the suspension performance cannot be tested; ④The scope of application is small, and it cannot reflect the internal factors of the suspension Sedimentation caused by uneven particle size; ⑤ There are many test vessels, many operating steps, and complicated operation; ⑥ Sampling after standing for a period of time will stir the suspension and cause errors; ⑦ High requirements for equipment accuracy, complex equipment structure, As the test device mentioned in CN102435538A; etc.

Abstract

The present invention relates to a suspension suspensibility measurement apparatus and a method for testing suspension suspensibility through a gravity center method. The suspension suspensibility measurement apparatus comprises a long tube-shaped test container, a clamper, a torque sensor and a support, wherein the clamper is fixed on a point on the test container, the other end is provided with a joint coupled with a test end of the torque sensor, the torque sensor is fixed on the support, a center axis line of the test end of the torque sensor is parallel to the horizontal plane, and is perpendicular to a center line of a test container length direction, the test container is obliquely placed, and the center line in the container length direction and the horizontal plane form an included angle theta. The invention further provides a method for testing suspension suspensibility through a gravity center method by using the apparatus. The apparatus and the method have the following characteristics that: test data is accurate, error is low, multiple test consistency of the same suspension is good, and suspensions with different suspensibilities can be well distinguished.

Description

technical field [0001] The invention relates to a suspension testing device and a method for testing the suspension performance of the suspension by a center of gravity method, belonging to the field of suspension testing. Background technique [0002] The suspension stability of the suspension is an important performance index of the suspension. However, there is no special test instrument for the suspension performance at present, and the commonly used methods are as follows: ①Static method of measuring cylinder: Pour a certain amount of suspension into the measuring cylinder, let it stand for a certain period of time, and observe the layered interface or supernatant Volume; ②Measurement of density at different heights: After the suspension is left to stand for a certain period of time, samples are taken at different heights to test the change of sample density; ③Standard volumetric weighing method: a set of standard container sampling cups is made, and the suspension The...
