espanolResumen En esta investigacion se estudian los efectos corrosivos del Biodiesel en la fundicion de hierro gris a temperatura ambiente. Los ensayos de inmersion estatica se realizaron mediante tecnicas gravimetricas con ausencia de luz y con cinco diferentes materias primas: sebo vacuno, manteca de cerdo, aceite de girasol, aceite de soya y aceite de coco. La afectacion de los acidos grasos que componen los diferentes Biodiesel fue determinada por medio de la regresion lineal con los datos obtenidos de velocidad de corrosion. Los resultados muestran que el Biodiesel con mayor nivel de insaturacion en su composicion es el que afecta la perdida de masa en el material de manera mas significativa, llevando a procesos mas corrosivos sobre la fundicion gris. portuguesResumo Esta pesquisa estuda os efeitos corrosivos do Biodiesel no ferro fundido cinzento a temperatura ambiente.

不同原料制备的生物柴油对灰铸铁的腐蚀性
本研究研究了生物柴油在室温下对灰铸铁的腐蚀作用。采用无光重量法对5种不同原料进行静态浸泡试验:牛脂、猪油、葵花籽油、大豆油和椰子油。采用线性回归法测定了不同生物柴油中脂肪酸的含量。本研究的目的是评估生物柴油对灰铸铁的腐蚀程度,并确定其成分中不饱和程度较高的生物柴油对灰铸铁的质量损失的影响。本研究研究了生物柴油在室温下对灰铸铁的腐蚀作用。采用无光重量法对牛油、猪油、葵花籽油、大豆油和椰子油五种不同原料进行静态浸泡试验。采用线性回归法测定了不同生物柴油中脂肪酸的作用,并对其腐蚀速率进行了评价。结果表明,不饱和酯浓度较高的生物柴油对材料质量损失的影响更显著,导致灰铸铁的腐蚀过程更强。EnglishAbstract corrosive effects of生物柴油》灰色iron at房间temperature民工studied theater。静态浸泡试验是通过重量法和无光法进行的,使用了五种原料:牛肉干、猪油、葵花籽油、大豆油和椰子油。根据腐蚀速率的数据,通过线性回归确定脂肪酸对生物柴油的影响。结果表明,不饱和脂肪含量较高的生物柴油对材料的质量损失有更显著的影响,导致在灰铸铁中发生更多的腐蚀过程。
