YJ-2102H Automatic Plaster Softening Point Tester Introduction:
This instrument is designed in accordance with the requirements of the Plaster Softening Point Determination Method in General Rule 2102 of the Fourth Volume of the Chinese Pharmacopoeia (2020 edition). It measures the temperature at which a plaster softens when heated under specified conditions, specifically the temperature when the plaster sags by 25mm due to heat. This value is used to test the consistency of the plaster and indirectly reflects its adhesive strength. The instrument is suitable for use by various plaster manufacturers, drug inspection institutes, and relevant institutions.
I. Main Technical Features
1. The YJ-2102H Automatic Plaster Softening Point Tester adopts technologies such as computer intelligent control, laser automatic detection, a liquid crystal touch screen human-machine interface, and lead screw stepper motor lifting. It features linear temperature rise, uniform bath stirring, and automatic sample testing. It is a high-automation, fast, convenient, and accurate instrument for testing the softening point of plasters.
2. The instrument heats both the heating tube medium and the plaster. A magnetic stirrer ensures uniform temperature in the beaker. The controller uses an interpolation algorithm to control the output, making the medium rise linearly at 1.0-1.5°C per minute. During heating, the plaster in the test ring gradually softens. When the softening point is reached, the plaster in the sample ring slowly descends in a droplet shape under the gravity of the steel ball. The average temperature when the plasters in both sample rings descend and touch the lower baffle is the softening point temperature of the plaster.
3. The instrument mainly consists of a chassis bracket, touch screen human-machine interface, lead screw lifting system, heating and temperature regulation system, laser detection system, and magnetic stirring system.
4. To facilitate test operation and the stable lifting of components in the beaker, a test platform is designed. The test components are suspended and positioned on the platform. The lead screw drives the platform and components to descend smoothly with precise positioning, ensuring the laser beam of the opposite射 laser is close to the upper side of the lower baffle.
5. The test process features animated simulation display, touch operation, and a human-machine interface, making it more intuitive and convenient.
6. Temperature control uses a slope interpolation algorithm for precise temperature rise, program control, and real-time temperature monitoring.
7. The split-type magnetic stirrer adopts infinite speed regulation, ensuring more uniform temperature.
8. The laser opposite射 automatically detects and judges sample descent, with strong anti-interference ability and high response sensitivity.
