如何快速判定电镀自攻钉的好坏

电镀，指通过电沉积的方式在金属、合金等材料表面镀一层锌使之达到防腐、美观等效果的一种表面处理方式。建筑螺钉也常采用电镀的方式进行加工，但如何判定它的优劣呢？今天以盈锋电镀自攻钉为例浅谈一二。对于电镀螺钉来说，产品性能是我们需要考量的第一位，因此我们从性能方面着手。

Electroplating refers to a surface treatment method in which a layer of zinc is plated on the surface of metals, alloys and other materials by means of electrodeposition to achieve anti-corrosion and aesthetic effects. Construction screws are also often processed by electroplating, but how to judge its advantages and disadvantages? Today, Infastech electroplating self-tapping nails are taken as an example.For electroplating screws, product performance is the first thing we need to consider, so we start from the performance aspect.

1.材质选择：作为源头，材质的选择是保障螺钉后期性能的重要一步，市面大多线材无法保证是否真的合规合标准，因此，购买螺钉前，我们应当要求对方提供材质报告，从源头上杜绝产品问题。盈锋镀锌螺钉可提供材质报告，也是毋庸置疑的。

Material selection：As the source, the choice of material is an important step to ensure the later performance of the screw, most of the wire on the market can not guarantee whether it is really compliant and standard, therefore, before buying the screw, we should ask the other party to provide a material report, from the source to eliminate product problems.Infastech galvanized screws can provide material reports, and there is no doubt about it.

2.镀层厚度：合理的镀锌层厚度能在有效提升螺钉的抗腐蚀性而不影响其攻入与安装的便捷性，可通过测量膜厚的方式进行检验。盈锋镀锌自攻钉要求锌层厚度最低保持6um，相比市场常见的产品而言，防腐性能也较占优势。因此，我们可通过所购买产品的检测报告确定膜厚参数，从而预估产品防腐性能如何。

Plating thickness：A reasonable thickness of the galvanized coating can effectively improve the corrosion resistance of the screw without affecting its accessibility and installation, and can be inspected by measuring the film thickness.Infastech galvanized self-tapping nails require the minimum thickness of the zinc layer to be 6um, which is also advantageous in anti-corrosion performance compared with common products in the market.Therefore, we can determine the film thickness parameters from the test report of the purchased product, so as to estimate the corrosion protection performance of the product.

3.盐雾要求：保持高盐雾要求也是保障螺钉防腐性能的重要环节，沿海等风雨侵蚀较严重的建筑对螺钉的盐雾要求尤其高。同上，也可通过检测报告的盐雾测试数据判定所购产品的防腐等级。盈锋镀锌螺钉要求自身盐雾效果达到200H（≥200H）无红锈，相较于市面同类产品表现更优一些。

Salt spray requirements：Maintaining high salt spray requirements is also an important part of ensuring the anti-corrosion performance of screws, and coastal buildings with serious wind and rain erosion have particularly high salt spray requirements for screws.As above, the anti-corrosion level of the purchased product can also be determined by the salt spray test data of the test report. Infastech galvanized screws require their own salt spray effect to reach 200H(≥200H) without red rust, which is better than similar products on the market.

4.氢脆要求：镀锌前需通过酸洗去除金属表面氧化膜从而强化锌层附着能力，但这一过程极易使螺钉产生氢脆现象，进而影响螺钉的韧性与硬度，不利于建筑安全。因此，我们通常可以通过氢脆测试的参数来判断所购产品质量的好坏。盈锋镀锌螺钉采用12小时以上去氢工艺，达到”0氢脆“要求，并通过48小时氢脆测试进行产品检验，整体要求相对严格。

Hydrogen embrittlement requirements：Before galvanizing, it is necessary to remove the oxide film on the metal surface through pickling to strengthen the adhesion of the zinc layer, but this process is very easy to produce hydrogen embrittlement of the screw, which in turn affects the toughness and hardness of the screw, which is not conducive to building safety.Therefore, we can usually judge the quality of the purchased products by the parameters of the hydrogen embrittlement test.Infastech galvanized screws adopt a dehydrogenation process of more than 12 hours to meet the requirements of "0 hydrogen embrittlement", and pass the 48-hour hydrogen embrittlement test for product inspection, and the overall requirements are relatively strict.

5.环保要求：市面上对镀锌螺钉的环保要求不尽相同，但事实上因建筑的特殊性，使用建筑螺钉应当着重考虑是否环保。盈锋镀锌螺钉采用三价环保锌，进一步加强螺钉的防腐性能，也免去客户对镀锌产品危害的顾虑。同样，我们可通过所购产品的检测报告来判断该产品是否可靠。

Environmental requirements：The environmental protection requirements for galvanized screws on the market are different, but in fact, due to the particularity of the building, the use of construction screws should focus on whether it is environmentally friendly. Infastech galvanized screws are made of trivalent environmentally friendly zinc, which further strengthens the anti-corrosion performance of the screws and eliminates customers' concerns about the hazards of galvanized products. Again, we can judge whether the product is reliable or not by the test report of the purchased product.

综上所述，我们可以通过要求供应商出具材质报告、检测报告等方式综合考量所购买电镀螺钉质量是否过硬，从而快速选定与自身需求相匹配的产品。自创立以来，盈锋德事隆品牌在行业深耕数十年，致力于为客户提供高品质、高防腐的紧固件产品以及高效、高匹配度的紧固件问题解决方案，如您正在为选不到合适的紧固产品而发愁，欢迎了解更多，盈锋（德事隆）乐意为您定制专属选配方案（不收费哦）。

To sum up, we can comprehensively consider whether the quality of the electroplating screws purchased is excellent by asking the supplier to issue material reports, test reports, quotations, physical observations and other ways, so as to quickly select products that match our own needs.Since its inception, the Infastech 德事隆 brand has been deeply cultivated in the industry for decades, and is committed to providing customers with high-quality, high-corrosion fastener products and efficient, high-matching fastener problem solutions.
