While sulfated caster oil, sulfited caster oil and sulfated fish oil could dramatically reduced hydrothermal stability of chrome-free tanned leather. 硫酸化蓖麻油、亚硫酸化蓖麻油与硫酸化鱼油会大大降低无铬鞣革的耐湿热稳定性。
Superior to the sulfated fish oil, sulfited fish oil and sulfated neats-foot oil, the tearing strength of the chrome-tanned leather which stuffed by the sulfonated oil SHO, STO, SEO. 磺化油SHO、STO、SEO改善铬鞣革撕裂强度的能力优于硫酸化鱼油、亚硫酸鱼油及硫酸化牛蹄油。
But the pH value and whether pre-treatment by sulfited fish oil have more effect to the applied performance. 其中中和结束时的pH值,是否用亚硫酸化鱼油预处理,对结果的影响较大。
