The main indicators for evaluating the combustion and fire resistance of thermal insulation products mainly include combustion performance index (flame spread speed and flame extension distance), pyrolysis performance (smoke density and smoke toxicity), and fire point and spontaneous combustion temperature.
First of all, the combustion and fire resistance index is one of the important indicators for evaluating the combustion performance of thermal insulation materials. For buildings, the occurrence and spread of fire have a key impact on the evacuation of personnel and fire fighting. Therefore, the flame spread speed and flame extension distance of thermal insulation materials should be as small as possible to reduce the speed and range of fire spread. The flame spread speed and flame extension distance of Jinfulai zero-level products are:
Secondly, the pyrolysis performance of thermal insulation materials is also one of the important indicators for evaluating their combustion and fire resistance. Pyrolysis performance refers to the smoke density and smoke toxicity generated after thermal decomposition of thermal insulation materials at a certain temperature. In a fire, thermal insulation materials will undergo pyrolysis reactions, producing a large amount of smoke and harmful substances. Smoke density refers to the density of smoke during combustion, and smoke toxicity refers to the degree of harm to the human body caused by toxic substances in smoke. If the smoke density and smoke toxicity of the insulation material are high, it will inevitably bring difficulties and dangers to the escape and fire fighting of personnel. The smoke density and smoke toxicity of Jinfulais rubber and plastic products are:
Again, the fire point and self-ignition temperature of the insulation material are also one of the indicators for evaluating the combustion fire resistance performance. The fire point refers to the lowest temperature at which the insulation material begins to burn, and the self-ignition temperature refers to the lowest temperature at which the insulation material automatically burns without an external heat source. If the fire point and self-ignition temperature of the insulation material are low, it is easy to spontaneously combust, which brings potential dangers to the use of buildings and equipment. The fire point and self-ignition temperature of Jinfulais rubber and plastic are:
By evaluating and controlling the combustion fire resistance performance indicators, the speed of fire spread can be effectively reduced, and the time and safety of personnel escape can be improved. Therefore, when selecting and using insulation materials, it is necessary to consider the combustion performance of the material and select materials that meet the requirements of equivalent building specifications and standards.
