TMA8311

Thermomechanical Analyzer

Measurement of a mechanical property change with respect to temperature

TMA is technique in which a non-oscillatory load is applied such as in compression, tension or bending, measuring the changes in the sample shape when the sample is heated or cooled. The TMA method includes measurement modes such as compression loading method, tensile loading method, penetration method and 3-point bending based on the sample shape and the objective of the measurement. TMA is widely used to measure the thermal expansion ratio and softening temperature of a sample.

TMA8311 Overview

Rigaku’s TMA adopts the differential expansion principle that cancels the thermal expansion or shrinkage generated from the detection mechanism itself. In addition to constant load, the load control can be set to two types: constant rate loading mode and sine-wave cyclic loading mode.

Sample controlled TMA (SCTMA), where the shrinkage rate controls the temperature, can be installed as an option that is effective for the simulation of sintering in ceramics, production of sintered materials with suppressed grain growth.

Dramituff Standard version

DRAMITUFF is a single component, air setting, castable. It has a very good abrasion resistance, cold crushing strength and chemical resistance. It can be hand packed or rammed in thin lining applications. DRAMITUFF is based on a proven binder system, which allows a wide range of water addition, giving working

Anchors for Fibers – Series D

Anchors produces refractory anchors for fibers (for insulating blankets, insulating boards/pannels, modules fibers). The fiber linings are common when we need the lining with good thermal shock resistance and a fast installation. Example : heat treatment furnaces. D1 : “Cerafix” type anchors «CERAFIX» type anchors : Anchors for fibers with

Support Brackets – Series C

Anchors produces refractory support brackets. Support brackets are used when the walls of the furnace are high.This enables to spread the weight on the refractory which reduces the risk of deterioration of the wall. They are also often placed around doors or < openings > to reinforce the refractory on
