HEAT-TRANSPIRATION AGENT COMPOSITION OF LONG HOUR TYPE FOR LIQUID-ADSORPTION WICK

摘要

PURPOSE:To obtain the subject heat-transpiration agent composition of a long hour type for a liquid-absorption wick capable of heat-transpiration for long hours without clogging thereof using a minimized amount of a solvent by blending an active component having a high vapor pressure of the subject heat-transpiration agent with a solvent having a boiling point lower than a specified temperature. CONSTITUTION:An active component having a high vapor pressure of the subjective heat-transpiration agent is mixed with a solvent having =350 deg.C boiling point, preferably an aliphatic hydrocarbon (paraffin-based hydrocarbon and unsaturated aliphatic hydrocarbon) having 150-350 deg.C boiling point, especially an n-paraffin, an isoparaffin, etc., free from practical toxicities or odors and having an extremely low fire hazard in an amount of about 6-80wt.%, preferably 10-75wt.%, especially 15-50wt.%, thus obtaining the above-mentioned objective composition capable of micronization of a medicine bottle because long hour type heat-transpiration can be carried out without clogging of a liquid-absorption wick using a minimized amount of the solvent and also capable of omission of a medicine bottle and use of the liquid-absorption wick alone without using the medicine bottle.
