Problems solved by technology

However, the current thermal protection tester cannot complete the dynamic change of the air layer thickness at the same time as the test. Therefore, in order to more truly reflect the thermal protection performance of the fabric system when the thermal protective clothing is used in a real environment, it is necessary to establish a new type of thermal protection thermal protection performance evaluation under the condition of dynamic change of air layer thickness

Abstract

The invention relates to a thermal protection property tester for a fabric system. The thermal protection property tester comprises a heat exposure simulation box, wherein a constant-temperature preheating board is arranged at the lower part inside the heat exposure simulation box, a fabric clamping device is arranged above the constant-temperature preheating board, and clamps a thermal-protective coating attached with a comfort layer, a water-proof ventilation layer, and an outer layer from top to bottom, a reciprocating lifting simulation skin system is arranged above the fabric clamping device, and ascends and descends in a reciprocating way through a speed-governing engine, a simulation skin sensor is connected with a computer through a simulation skin temperature data collecting system, temperature and humidity sensors are respectively arranged between the thermal-protective coating attached with the comfort layer and the water-proof ventilation layer, between the water-proof ventilation layer and the outer layer, above the thermal-protective coating attached with the comfort layer and inside an under-coat air layer, outside the outer layer and inside a static air layer, and are connected with the computer through a temperature and humidity data collecting system. The thermal protection property tester can be used for truly simulating the real using condition of the thermal protection garment and equipment in the fire rescue scene.

Description

technical field [0001] The invention relates to the technical field of thermal protection safety, in particular to a thermal protection tester for fabric systems. Background technique [0002] The thermal protective clothing fabric system includes an outer layer, a waterproof and breathable layer, a thermal insulation layer and a comfortable layer. The thermal protection test is to objectively and quantitatively evaluate and study the thermal protection performance of the thermal protective clothing fabric system. The thermal protection testers currently used mainly include ASTMD4108 open flame method fabric thermal protection test, NFPA1977 fabric thermal radiation protection test, NFPA1971 thermal radiation and heat convection mixed action protection performance test, etc. The thermal protection tester is generally composed of a heat source device, a heat source preheating shielding device, a sample clamping device, a heat flow meter, and a drawing recorder. Different test...
