Description

一种现场金属挂片腐蚀试样架
技术领域
本实用新型涉及一种腐蚀架,特别是涉及一种现场金属挂片腐蚀试样架。
背景技术
随着我国经济建设的飞速发展以及环境的污染,钢材等金属的腐蚀所造成的浪费十分巨大。每年由于腐蚀造成的损失难以估量。据报道,我国每年因金属腐蚀引起的损失约为国民生产总值的2.3%。目前,防止金属腐蚀已成为科学研究中的重大问题,然而,一些科研人员往往趋向于在实验室利用仪器设备来探究金属腐蚀的原理,从而找到防止其腐蚀的办法,也有一些科研人员与企业合作,将待测金属试样简单的放到企业中进行现场模拟实验,由于待测试样为金属,当待测试样与不锈钢支架在腐蚀液体中接触时,会发生电偶腐蚀。电偶腐蚀是由于腐蚀电位不同,造成同一介质中异种金属接触处的局部腐蚀,会对待测试样造成损坏,所以避免异种金属接触是防止电偶腐蚀的必要条件。
测量金属试样腐蚀情况时,现场实验中往往把待测试样用铁丝或其它材料的细丝悬挂在现场,使其完全浸入到腐蚀介质中,经过一定时间后,再从中取出,观察表面腐蚀形貌,然后除锈后称重,计算腐蚀速率。由于现场腐蚀环境往往比较复杂,便于悬挂的位置不佳,即使能够有悬挂的位置,但是可能面临腐蚀介质浸泡不充分的情况,不能较好的了解其腐蚀情况。另外,悬挂的试样不稳定,摆动性大,在现场浸泡时容易丢失,不易找到。试样与金属支架之间也会存在电偶腐蚀,影响实验结果的准确性。目前,公开一种装置来解决以上存在的一些问题显的尤为重要。
发明内容
本实用新型所要解决的问题在于公开一种新装置来解决以往在现场挂片实验中存在的问题。为此,研制了一种由不锈钢和绝缘支架组成的现场金属挂片腐蚀试样支架,能够最安全有效的将待测试样放入现场复杂的环境中进行腐蚀试验,从而保证实验的可靠性。
所采用技术方案是:本实用新型现场金属挂片腐蚀试样支架包括不锈钢支架,绝缘支架,螺栓螺母若干。其中不锈钢支架起固定支撑作用,上面有圆形开孔,用于固定绝缘支架,绝缘支架是绝缘材料聚四氟乙烯,聚四氟乙烯具有优良的耐蚀性和绝缘性。可以避免待测金属试样与不锈钢支架之间发生电偶腐蚀,并且该支架长期浸泡在腐蚀介质中绝不会发生腐蚀。绝缘支架由试样台和挡片组成,试样台上有长方体试样槽,用于放置待测试样,试样放在槽内用挡片固定住,可以防止试样丢失,试样台和挡片上有气液流通通道,能保证试样与环境流体充分接触,腐蚀液体在其中可以自由流动,试样台和挡片用螺栓螺母固定住,最后固定在不锈钢支架上。
本实用新型的优越效果是,
1.采用绝缘材料,避免待测试样与支架之间发生电偶腐蚀,从而影响实验结果;
2.采用试样槽固定试样,避免试样对现场设备以及生产工艺产生影响;
3.采用气液流通通道使试样与环境流体充分接触,保证实验数据的真实可靠;
4.样品固定在绝缘架中不易丢失,整个装置便于固定,可以充分选择最佳腐蚀环境。
