SJY-II-17 Imaging Sintering Point Tester (Optical dilatometer)
The instrument is a high-temperature transmission projection device used in measuring sintering point, melting point and refractoriness temperature of sand, glass, compound and refractory, ceramic raw material, metal material surface contact angle. The tester can clearly see situation of sample volume contraction, expansion purification and completely spherify, interface contact angle at high temperature on the screen and informed of corresponding temperature of all kinds of situations. Provide basis for production of material selection, and provide test method for scientific research and teaching. Widely used in casting, ceramic, glass ect. industries and teaching, scientific research departments. Main technical parameters: 1. Heating temperature: max 1700 oC, Furnace diameter: 30mm; 2. Heating rate: 0-20oC / min (can be set). Process controls temperature, regulated by intelligent PID, temperature control accuracy: ± 1, it can set up a platform for more than 32 segments; 3. Image magnification: 8~9 times. Imaging coordinates can be easy to quantify expansion, and contract data; 4. Minimum interval storage temperature image: 1, it can be arbitrarily set; 5. CCD camera pixels: ≥ 10 million pixels; 6. Supply voltage: 220V ± 10%, 2.5KW; 7. Instrument equipped with standard computer interface, tests are controlled by computer; 8. Image processing software has the functions of image storage, image printing, interface contact angle analysis, analysis of systolic expansion data, historical data query, etc; 9. Samples maximum size (mm): 6(diameter) ×8(thickness), cylinder or square. It can also be customized according to user requirements; 10. Instrument Technology: Sintering temperature measurement: eyeballing method and image contraction method. Refractoriness (melting temperature): the temperature when graphics becomes round can be identified as melting temperature or refractoriness;
