Stock Status: On The Way


In the Chemical Industry, for all potential Runaway Reactions are always the most important thing in the security control, such as heat loss possibility, environmental conditions, and the scale of runaway situation - R&D, process development, manufacturing, transportation, storage. Typically, the runaway reaction in different quantity of reactive chemicals has different results, for example:
[Heat Loss] small vessel: more heat; large vessel: more adiabatic
[In The Same Temperature] small vessel: stable; large vessel: unstable
[Runaway Result] small vessel: burning; large vessel: exploring

THT's ARC acceleting was designed based on such kind of requests. ARC helps those researchers to define those runaway conditions and avoide accidents since the product development stage, for those reactive chemicals and battery products.

To simulate the real-life or large scale scenario, the sample under investigation must be in an environment without heat loss (or gain). The adiabatic environment best reproduced in the ARC. The process is so called heat-wait-seek.

The temperature where the heat production exceeds the heat loss is the Temperature of No Return (TNR).
