Embodiment Construction

[0023] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] To perform a rheological test, the user needs to first turn on the power of the instrument and turn on the microcomputer (1).

[0025] After the rheological property testing software is started from the microcomputer (1), the user inputs the relevant setting values ​​of the experimental scheme according to the prompts on the interface of the rheological property testing software, including test temperature, warm-up time, test rate sequence, and test rate switching control mode, switching trigger value. Among them, the control mode of test rate switching has the following four options for the user to choose: one is that the time spent at the current test rate exceeds the time specified by the user in "Switch Trigger Value", and the other is the moving distance of the plunger rod at the current test rate Exceeding the length specified by...

Abstract

The invention discloses a computer-based rheology test control method and a system. The method comprises the following steps that: the user starts rheological property testing software through a micro-computer at first during a rheological test and inputs relevant settings of a test scheme following prompts, and a rheology test device starts testing the first rate in a test rate sequence; test rate switching conditions are periodically judged during testing, if the conditions are not satisfied, the current rate is tested continuously, and if the conditions are satisfied, the test rate is switched to a next rate in the test rate sequence for testing; and the previous steps are repeated until all rates in the test rate sequence are tested, the test data are analyzed and processed, and the processing results are displayed on the software interface and are simultaneously stored. The invention realizes the automation of the rheology test, improves the accuracy of the pressure and temperature data, and has the advantages of simple operation and accurate testing.

Description

technical field [0001] The invention relates to the field of testing instruments, in particular to a testing system for rheological properties of materials. Background technique [0002] Rheometer is an essential instrument for testing the rheological properties of materials, and is widely used in technical research and analysis in the fields of plastics, petrochemicals, soil, blood, etc. According to different working principles, rheometers can be divided into capillary rheometers, torque rheometers and rotational rheometers. Capillary rheometers are the most widely used due to their wide range of shear rates. [0003] The Chinese patent with the application number 200810143934.5 introduces a method and device for testing the rheological properties of polymer composite materials, which can measure the extrusion molding process, capillary extrusion process, injection molding process of polymer composite materials under the action of physical field strengthening. The rheolo...
