Usually, HEDP is used together with polycarboxylic acid. 貯于室內(nèi)陰涼通風處，防潮，貯存期十個月。
The scale and corrosion inhibition of polyaspartic acid and its mixture of phosphorous water treatment agent (HEDP, PBTCA, DETPMP) is discussed. 摘要研究了聚天冬氨酸及其與膦系水處理劑(HEDP、PBTCA、DETPMP)復合的阻垢緩蝕性能。
The performance of scale inhibition was researched and the results were compared with HEDP, PBTCA, HPMA and PAA. 將聚合物與常規(guī)阻垢劑HEDP、PBTCA、HPMA、PAA進行比較。
Moreover, there is a chiral quaternary carbon in the1-hydroxyethylidenediphosphonic (hedp) ligand. 證實1-羥基乙叉-1,1-二膦酸配體(hedp)中的季碳為手性碳原子。
The experimental result shows that the scale inhibition of PESA is prior to HEDP and HPMA,but inferior to PBTCA. 結果表明,PESA比常用藥劑HEDP、HPMA的阻垢性能好,但比PBTCA性能稍差;
