High-Temperature Physical Properties Analyzer
Published: 8/19/2015
The SJY-II-14/17 is a high-temperature imaging analyzer for determining sintering point, refractoriness, dimensional change, and contact angle of sands, refractories, ceramics, and related materials. It supports programmable heating and image-based analysis for industrial QA, R&D, and education in foundry, ceramics, and glass sectors.
Product Description
The SJY-II-14/17 is a transmission-projection imaging system designed to observe and quantify material behavior under high temperature. It enables clear visualization of sample shrinkage, expansion, purification, and interface contact angle on a screen while recording the corresponding temperatures at which these events occur.
Typical applications include measuring sintering point and refractoriness of molding sands, refractories, and ceramic raw materials, as well as surface contact angles on metals. The instrument integrates computer control and image-processing software for image storage/printing, contact angle analysis, dimensional change analysis, and historical data review, serving production material selection and laboratory research needs.
