Abstract

Abstract Lubricanting greases from waste frying vegetables oils with natural fibers additives could be the answer to the sustainable production of greases. Also, their biodegradability makes them more acceptable for the environment, having in view increasingly strict regulations in domain. In this experimental work, twenty lubricant formulae were created from waste sunflower oil and waste palm oil with calcium or lithium stearate as thickener and cellulose or lignin additives. All were rheologically tested and characterized as Bingham fluid with good consistency and plasticity. The penetration tests confirmed the good consistency, categorizing these products from normal to firm, very firm and hard lubricant greases comparable to those conventionally obtained from mineral oils.
由可再生材料制成的新型润滑脂的流变学
从废油炸植物油中添加天然纤维添加剂制备润滑脂可能是油脂可持续生产的解决方案。此外,鉴于该领域日益严格的法规,它们的生物降解性使它们更容易为环境所接受。本实验以废葵花籽油和废棕榈油为原料,以硬脂酸钙或锂为增稠剂,纤维素或木质素为添加剂,制备了20种润滑油配方。经流变学测试,均为Bingham流体,具有良好的稠度和可塑性。渗透测试证实了良好的一致性,将这些产品分为普通、坚固、非常坚固和坚硬的润滑脂,与传统的矿物油相媲美。
