Ministry of Chemical Industry of the People's Republic of China Standard Method for determination of viscosity of rubber paste
(rotational viscometer method)
HG 4--1470--82
Change to HG/T 3 323 -1981
This standard applies to the determination of absolute viscosity of butyl rubber paste. 2 Definition
Viscosity is the internal friction of a fluid, which is the resistance of a layer of fluid to relative motion with another fluid, expressed in eP. 3 Instruments and equipment
3.1 Rotational viscometer: The measurement error is less than =0.5%. Step motor
Scale reading pad
Measured liquid
Structure diagram of rotational viscometer
Super constant temperature bath: temperature fluctuation range is ±0.5℃. 3.2
3.3 Thermometer: Graduation 0.1℃.
Container: 6-7cm diameter, container with a height of not less than 11cm or a stopwatch attached to the rotational viscometer. 3.5
Stopwatch: Accuracy 0.25
Sample requirements
4.1 Uniform and free of bubbles.
4.2 Sufficient number,
5 Test steps
5.1 According to the viscosity of the sample, select the appropriate rotation speed, and the continuous reading is within the range of 0% to 85% of the dial. Ministry of Chemical Industry of the People's Republic of China 1982-02-23 Issued 212-01 Implementation on 19th
HG 41470--82
5.2 Dip the rotor straight into the center of the sample (avoid bringing in bubbles) so that the liquid surface reaches the liquid level mark of the rotor (if there is a protective frame, E should be installed)
5.3 Keep the sample and rotor in the test container at a constant temperature of 25+2C (if the product standard has other provisions on the test temperature, follow the provisions of the product standard) and keep the sample temperature uniform. 5.4 Read the indicated value when the rotor rotates 1+0.034min. Note: When measuring the material sample, read the reading when it rotates 2=row.031mit. Test results
Calculate according to the instrument requirements.
The test result is the average value of the two parallel test values. The test report should include:
The source, type, manufacturing date, test date of the sample, the model of the rotational viscometer used:
The registration number:
The speed used, rpm:
The temperature of the sample at the end of the test,,
Viscosity, cP
Additional instructions;
This standard was proposed by the Beijing Rubber Industry Research and Design Institute of the Ministry of Chemical Industry and is under the jurisdiction of the Beijing Rubber Industry Research and Design Institute. This standard was drafted by the Shanghai Rubber Products Research Institute. The main drafters of the standard are Yang Xiuhong and Hong Aiwei. This standard is entrusted to the Beijing Rubber Industry Research and Design Institute for interpretation. 5 No.: 15169-2-4878
