Compuesto de Goma para Neumáticos — Decomposición
Junto a la parte plastificante (cerca del 7%), los primeros componentes elastómeros durante la descomposición de un compuesto de goma se derivan a 383°C (38%) y los segundos a 448°C (31%).
La parte de Negro de humoTemperature and atmosphere (purge gas) affect the mass change results. By changing the atmosphere from, e.g., nitrogen to air during the TGA measurement, separation and quantification of additives, e.g., carbon black, and the bulk polymer can become possible.negro de humo se calcula en un 20% y el Contenido en cenizasThe ash is a measure of the mineral oxide content on a weight basis. Thermogravimetric analysis (TGA) in an oxidative atmosphere is a well-proven method to determine the inorganic residue, commonly referred to ash, in organic materials such as polymers, rubbers, etc. Therefore, the TGA measurement will identify if a material is filled and calculates the total filler content.contenido en cenizas en un 4%. La posición de las temperaturas de pico de las curvas TGA derivadas (DTG) muestra que el compuesto es una mezcla de goma NR/SBR llena de Negro de humoTemperature and atmosphere (purge gas) affect the mass change results. By changing the atmosphere from, e.g., nitrogen to air during the TGA measurement, separation and quantification of additives, e.g., carbon black, and the bulk polymer can become possible.negro de humo.
