This instrument is designed and manufactured in accordance with the requirements specified in the determination of softening point in the standard GB/T 8143 "Test Methods for Shellac Products", and is applicable to the determination of the softening point of shellac by the method specified in the standard. Shellac is a mixture of polyhydroxycarboxylic acids, and the measured softening point is only the average softening point of the mixture.
I. Main Technical Features of YJ-8143C Automatic Shellac Softening Point Tester
This instrument adopts technologies such as computer intelligent control, automatic laser detection, liquid crystal touch screen human-machine interface, and lead screw stepper motor lifting. It has the characteristics of linear temperature rise, uniform bath solution stirring, and automatic completion of sample detection. It is a shellac softening point tester with high automation, fast and convenient testing, and accurate and reliable test results.
Determination procedure: Place the two rings filled and compacted with samples into the sleeve holes of the ring frame of the softening point tester respectively, place the ring frame in a beaker filled with newly boiled and cooled water, make the water temperature rise evenly, keep the water temperature rising at 5 ℃ ± 0.5 ℃ per minute after starting heating for 3 minutes, the sample softens gradually, and the result is recorded automatically.
