针对中国石油吉林石化公司产三元乙丙橡胶J-4045开展试验。通过调整J-4045配方中过氧化物硫化剂的加料量,研究了过氧化二异丙苯(DCP)用量以及温度对J-4045硫化性能的影响。利用无转子硫化仪测试了9个样品分别在140℃、150℃、160℃、170℃时的硫化曲线,找出了J-4045采用DCP充当硫化剂的最佳温度为160℃,发现了J-4045的DCP硫化体系正硫化时间与DCP用量无关,只与硫化温度有关,最大扭矩随DCP用量增加而增加,门尼焦烧时间随DCP用量增加而变短。
为生产出易于人体吸收的锌补充剂,提高加工副产物罗非鱼皮的利用价值,该试验以锌离子螯合率为指标,筛选最佳活性的胶原蛋白肽,通过高效液相色谱对其分子质量分布进行测定。运用紫外光谱、傅里叶红外光谱、原子力显微镜和扫描电镜对螯合前后的结构变化进行表征。此外,采用体外模拟胃肠道消化模型,对肽-锌螯合物中锌离子溶解率进行评估。研究结果表明,碱性蛋白酶制备的胶原蛋白肽的锌离子螯合率在6 h达到最高值0.075μmol/mg;其在200~1000 Da区间分布占比89.49%;紫外和红外光谱结果表明,胶原蛋白肽的酰胺键、
呕吐毒素在玉米、小麦和大麦等谷物和禽畜饲料中检出率很高,是污染最严重的霉菌毒素之一,严重危害食品安全。因此,如何高效安全地去除呕吐毒素成为研究的热点。相比传统的物理和化学处理方法,生物降解法因具有高效、对环境友好和特异性强等优势而广受关注。作者概述了生物降解呕吐毒素的方法,重点总结了降解菌株的种类、降解酶及其基因,并且阐述了其在实际应用中的局限和前景。
