镀锌方管在玻璃幕墙中有哪些使用?

一、镀锌方管板的内在要素,我们都晓得的是镀锌方管中镍含量低下,镀锌方管的钝化性能就低,所以镀锌方管中马氏体含量和铬跟镍的含量对镀锌方管板外表的钝化性能影响很大。

First, the intrinsic factors of galvanized square tube sheet are that the nickel content in galvanized square tube is low and the passivation performance of galvanized square tube is low. Therefore, the martensite content and the chromium and nickel content in galvanized square tube sheet have great influence on the passivation performance of galvanized square tube sheet.

二、镀锌方管板运用环境中的介质,镀锌方管的钝化膜在热力学中是属于受抑止的亚稳态架构,它所发挥的维护作用于所处的环境中的介质有关。但是不管在哪种环境中运用,在运用的过程中,都要对镀锌方管板停止定期的清洗来除去镀锌方管板外表附着的有害物质。

2. The passivation film of galvanized square tube belongs to the restrained metastable structure in thermodynamics. The maintenance of the passivation film is related to the medium in the environment. However, no matter what kind of environment is used, in the process of operation, the galvanized square tubesheet should be cleaned periodically to remove the harmful substances attached to the surface of the galvanized square tubesheet.

三、镀锌方管板的外表清洁度。关于镀锌方管合金来说,镀锌方管的外表越润滑粗糙度越低,那么该镀锌方管外表就越难有异物附着上,异物不易附着,那么对镀锌方管外表的腐蚀也就降到了低点,所以镀锌方管外表要尽量采用精加工的外表。另外镀锌方管板的后的钝化后的清洗也应该认真停止,这样才干使剩余的酸液促进阳极反响,维护膜层的完好性,保证镀锌方管板的外表的耐腐蚀性加强。

3. Exterior cleanliness of galvanized square tube sheets. As for galvanized square tube alloy, the lower the lubrication roughness of galvanized square tube is, the harder the foreign body attaches to the surface of galvanized square tube, and the foreign body is not easy to attach, so the corrosion to the surface of galvanized square tube will be reduced to the lowest point, so the galvanized square tube should adopt the finishing appearance as far as possible. In addition, the final passivation cleaning of galvanized square tube sheet should also be seriously stopped, so that the remaining acid can promote the anode response, maintain the integrity of the film, and ensure that the corrosion resistance of the galvanized square tube sheet is strengthened.

四、 氯离子,氯离子对镀锌方管板镀膜的危害是极大的,所以,我们在对镀锌方管板的外表停止钝化过程中要严厉控制钝化液中的氯离子的含量,基于氯离子对镀锌方管板的危害性。很多钝化用化学资料对氯离子都有着限量的请求,在配置钝化液用水和清洗用水也对氯离子有着严厉的水质请求,来保证钝化废品中不含有氯离子。

4. Chloride ion and chloride ion are very harmful to galvanized square tube sheet. Therefore, we should strictly control the content of chloride ion in the passivation solution during the process of stopping passivation of galvanized square tube sheet, based on the harmfulness of chloride ion to galvanized square tube sheet. Many passivation chemical materials have limited requirements for chloride ions. Water for passivation solution and cleaning water also have strict water quality requirements for chloride ions to ensure that passivation waste does not contain chloride ions.

镀锌方管在氯离子存在下的环境中,腐蚀很快,以致超越普通的低碳钢。关于承受流体压力的钢管都要阻止液压实验来检修其耐压才干和质量,在划定的压力下不发作透露、浸湿或收缩为合格,有些钢管还要根据尺度或需方恳求阻止卷边实验、扩面实验、压扁实验。

Galvanized square tubes are corroded rapidly in the presence of chloride ions, so that they exceed ordinary low carbon steel. As for steel pipes under fluid pressure, hydraulic tests should be prevented to repair their ability and quality of withstanding pressure. Under the specified pressure, no disclosure, wetting or shrinkage should occur, and some steel pipes should also be prevented from edge-rolling, flattening and flattening experiments on the basis of scale or requirement.
