钢铁表面的ATMP钝化处理 总被引:2,自引:0,他引:2
利用加速腐蚀试验、电化学极化测量以及扫描电镜对氨基三甲撑膦酸(ATMP)在钢铁表面的防护效果进行了研究。测定了ATMP溶液的浓度、温度、pH及处理时间对膜层抗蚀性的影响。通过与多种有机瞵酸进行比较,确认ATMP具有较好的表面防护效果。 相似文献

HPMA和ATMP的缓蚀阻垢性能 总被引:4,自引:2,他引:2
水解聚马来酸酐(HPMA)和氨基三甲叉膦酸(ATMP)的缓蚀和阻垢性能都有量佳浓度值,在要同条件下HPMA的缓蚀、阻垢性能优于ATMP,两种药剂的阻垢率均随Ca^2+浓度的增加而提高,D PH为6~9时两种申报后率比较稳定。 相似文献

PBTCA、HEDP、ATMP缓蚀性能的理论研究 总被引:6,自引:1,他引:5
从常用水处理药剂中选择3种有机膦药剂PBTCA(2-膦酸基丁烷-1,2,4-三羧酸)、HEDP(羟基亚乙基二膦酸)、ATMP(氨基三亚甲基膦酸)与ClO2、ZnSO4复配,通过正交试验确定了最佳配方,并利用从头计算法对该配方进行了量子化学计算,分析了缓蚀性能和分子结构的关系.结果表明:P原子净电荷Qp电荷密度、分子的最低空轨道能ELUMO与缓蚀率有较好的相关性.同时,计算了Fe和ClO2的最高占有轨道能EHOMO和最低空轨道能ELUMO以及二者的差值△E,说明缓蚀剂供出电子与Fe作用的趋势要大于接受电子与Fe作用的趋势,而且PBTCA、HEDP和ATMP耐二氧化氯氧化的能力与缓蚀剂最低空轨道能与二氧化氯最高占有轨道能的差值(LUMOinhib-HOMOClO2值)有较好的相关性,试验数据也表明了缓蚀机理的正确性. 相似文献

采用静态阻垢法,研究了聚天冬氨酸(PASP)与氨基三甲叉膦酸(ATMP)复配体系的协同效应,考察阻垢剂添加量、温度、pH值、Ca2+浓度、HCO3-浓度对阻垢性能的影响。结果表明,复配体系的阻垢性能较单一阻垢剂好,PASP/ATMP质量比在2∶3时,阻垢性能最优,当复合阻垢剂PASP-ATMP投加量为5 mg/L时,阻垢率高达93.04%。复配体系阻垢性能随温度、pH值、Ca2+浓度、HCO3-的增加虽然有所下降,但仍表现出一定钙容忍度及适合高pH值、高HCO3-环境使用等特性。 相似文献

对氨基三亚甲基膦酸产品标准存在问题的剖析 总被引:1,自引:0,他引:1
通过试验实验室试验,剖析了ATMP产品标准(ZBG71003-1989与HG/T2841-1997)存在的问题,认为标准中应增加ATMP含量这一指标,以免产品中主要成分为IDPA也判断为ATMP,影响产品质量,期待能尽快完善ATMP标准。 相似文献

The transplantation of various immune cell types are promising approaches for the treatment of ischemic cardiovascular disease including myocardial infarction (MI) and peripheral arterial disease (PAD). Major limitation of these so-called Advanced Therapy Medicinal Products (ATMPs) is the ischemic microenvironment affecting cell homeostasis and limiting the demanded effect of the transplanted cell products. Accordingly, different clinical and experimental strategies have been evolved to overcome these obstacles. Here, we give a short review of the different experimental and clinical strategies to solve these issues due to ischemic cardiovascular disease. 相似文献

Amino trimethylene phosphonic acid (ATMP) is a common scale inhibitor using in oil field that always combines with a variety of surfactants and auxiliaries. It is necessary to know its solubility for purifying and combining. With a laser monitoring observation technique, the solubility of amino ATMP in binary solvent mixtures were measured by using the isothermal method from 298.15 to 343.15 K. Results of these measurements were correlated by the combined nearly ideal binary solvent (CNIBS)/Redlich-Kister equation. For these data studied, the CNIBS/Redlich-Kister equation was found to provide an accurate mathematical representation of the experimental data. 相似文献
