【1KG起售】HEDP 羟基乙叉二膦酸 缓蚀阻垢剂 液体含量50%/60% 另有固体

 

一、产品介绍:

    CAS:2809-21-4
    分子式:C2H8O7P2
    相对分子质量:206.02
    HEDP是一种有机膦酸类螯合剂,无毒无污染。能与铁、铜、锌等多种金属离子形成稳定的络合物,能溶解金属表面的氧化物,在250℃下仍能起到良好的缓蚀阻垢作用,在高pH值下仍很稳定,不易水解,一般光热条件下不易分解。耐酸碱性、耐氯等氧化剂的氧化性能较其它有机膦酸(盐)好。可与水中金属离子,尤其是钙离子形成六圆环螯合物,螯合力强,阻垢效果好。
    HEDP耐碱性能好,在纺织印染等行业用作金属离子螯合剂和氧漂稳定剂,抑制过氧化物在局部的过度分解,抗破洞作用显著。
    HEDP固体属于高纯产品,适用于冬季严寒地区。

三、产品用途:

    HEDP广泛应用于电力、化工、冶金、化肥等工业循环冷却水系统及中、低压锅炉、油田注水及输油管线的阻垢和缓蚀;用作金属和非金属的清洗剂,漂染工业的过氧化物稳定剂和固色剂,电镀工业的络合剂。HEDP作阻垢剂一般使用浓度1~10mg/L,作缓蚀剂一般使用浓度10~50mg/L;作清洗剂一般使用浓度1000~2000mg/L;通常与聚羧酸型阻垢分散剂复配使用。

    HEDP在纺织印染的前处理—煮练、漂白、染色工序中用作螯合分散剂和稳定剂,可配成不同浓度,含量以30%为佳,调节合适的PH值,好能调成钾盐。用量1~4g/L。

 

四、包装存储:

    HEDP液体用塑料桶包装,每桶25Kg或250Kg;可根据客户需求,提供1KG/包等个性化包装,详情可咨询在线客服。
    HEDP固体用内衬聚乙烯袋的塑料编织袋包装,每袋净重25kg,也可根据用户需要确定。可根据客户需求,提供1KG/包等个性化包装,详情可咨询在线客服。
    贮于室内阴凉通风处,防潮,贮存期十个月。
