当看到实验室里的瓶瓶罐罐,您会对化学产生浓厚的兴趣吗?化学,可以创造出新元素,新物质,在探索的过程,就是解开奥秘追寻真理的过程。

When you see the bottles in the lab, do you have an interest in chemistry?Chemistry, which can create new elements, new substances, in the process of exploration, is the process of unlocking the mystery and pursuing the truth.

化学是以实验和认识物理反应的一门科学,从人类使用火开始,到使用铜器、铁器、陶瓷、玻璃,古代的四大发明(火药、指南针、造纸、印刷术),再到现在的玻璃钢、合成塑料、纳米技术,我们的衣食住行、航空、航天都离不开化学,就连我们天天用的手机,包括屏幕、外壳、电池、电路,共包含了30种化学元素。

Chemistry is an experiment and understanding of physical reaction science, from human use of fire, to the use of copper, iron, ceramics, glass, ancient four great inventions (gunpowder, compass, paper, printing), to now FRP, composite plastic, nanotechnology, our food, clothing, transportation, aviation, aerospace without chemistry, even we use the mobile phone every day, including screen, shell, battery, circuit, contains 30 kinds of chemical elements.

那么,钢材常说的镀锌铝镁又是什么呢?

So, steel is often said galvanized aluminum magnesium?

镀就是利用电解原理在某些金属表面上镀上一薄层其它金属或合金的过程,是利用电解作用使金属或其它材料制件的表面附着一层金属膜的工艺从而起到防止金属氧化(如锈蚀),提高耐磨性、导电性、反光性、抗腐蚀性(硫酸铜等)及增进美观等作用。

Plating is the use of electrolysis principle on some metal surface plating a thin layer of other metal or alloy process, is the use of electrolysis to metal or other material parts surface attached to a layer of metal film process to prevent metal oxidation (such as corrosion), improve corrosion resistance, conductivity, reflective, corrosion resistance (copper sulfate, etc.) and improve beauty.

不但是人体必需的微量元素之一,在人体生长发育、生殖遗传、免疫、内分泌等重要生理过程中起着极其重要的作用。而且锌是一种浅灰色的过渡金属在现代工业中对于电池制造上有不可磨灭的地位,为一相当重要的金属,锌的化学性质活泼,在常温下的空气中,表面生成一层薄而致密的碱式碳酸锌膜,可阻止进一步氧化从而有效延长物品的使用寿命和抗酸碱抗腐蚀能力可以算作一种工业品外表保护处理。

Zinc is not only one of the essential trace elements of the human body, but also plays an extremely important role in human growth and development, reproductive genetics, immunity and endocrine.And zinc is a light gray transition metal, in the modern industry for battery manufacturing has indelible status, is a very important metal, zinc chemical nature, in the air at room temperature, the surface of a thin and dense alkali zinc carbonate film, can prevent further oxidation, thus effectively extend the service life of goods and acid and alkali corrosion resistance, can be counted as an industrial appearance protection treatment.

铝为银白色轻金属延展性在潮湿空气中能形成一层防止金属腐蚀的氧化膜。是用作炼钢时的脱氧定氮剂,细化晶粒。抑制低碳钢的时效,改善钢在低温时的韧性,特别是降低了钢的脆性转变温度,提高钢的抗氧化性能。

Aluminum is silver white light metal, ductile, can form a layer of oxide film to prevent metal corrosion in humid air.It is used as deoxyand nitrogen agent for refining grains.Reduce the aging of low-carbon steel, improve the toughness of steel at low temperature, especially reduce the brittle transition temperature of steel, improve the antioxidant performance of steel.

镁(Magnesium)在自然界广泛分布,人体的必需元素之一是一种银白色的轻质碱土金属,化学性质活泼,能与酸反应生成氢气,具有一定的延展性和热消散性。。常用做还原剂中国鞍钢、宝钢、武钢、本钢、包钢、攀钢、首钢等钢厂已经用镁粉深脱硫,获得优质钢,取得良好效果

Magnesium (Magnesium) is widely distributed in nature, and is also one of the essential elements of the human body. It is a silver-white light alkali soil metal, with lively chemical properties, and can react with acid to produce hydrogen, with a certain ductility and heat dissipation.Commonly used as reducing agent, China Angang, Baosteel, Wugang, Bensteel, Baotou Steel, Panzhihua Steel, Shougang and other steel mills have used magnesium powder deep desulfurization, to obtain high-quality steel, has achieved good results.

镀锌铝镁钢板的合金镀层是由锌Zn,铝Al6%,镁Mg3%高温固化形成。

The alloy coating of galvanized aluminum and magnesium steel plate is formed by the high-temperature curing of zinc Zn, aluminum Al6%, and magnesium Mg3%.

镀锌铝镁产品特性

Galvanized aluminum and magnesium product characteristics

1、热镀锌铝镁钢板镀层中添加了Al、Mg及Si等合金元素,大大提高镀层腐蚀抑制效果,与普通的镀锌产品相比,镀层附着量少却能实现更出色的耐腐蚀性,是热浸镀锌钢板的10~20倍。

1. Al, Mg and Si are added to the hot-dip galvanized aluminum and magnesium steel plate plating, which greatly improves the corrosion inhibition effect of the coating. Compared with ordinary galvanized products, the coating has less attachment but can achieve better corrosion resistance, which is 10~20 times that of the hot-dip galvanized steel plate.

2、切割面周边的镀层成分不断溶出,形成主要由氢氧化锌、碱性氯化锌及氢氧化镁等组成的致密保护膜,这种保护膜导电性较低,对切割面的腐蚀有抑制效果。

2. The coating components around the cutting surface are constantly dissolved, forming a dense protective film mainly composed of zinc hydroxide, alkaline zinc chloride and magnesium hydroxide. This protective film has low electrical conductivity and has an inhibitory effect on the corrosion of the cutting surface.

3、由于超级耐蚀能力达到普通热镀锌板的10-20倍和切割断面的耐腐蚀自我愈合功效,使用热镀锌铝镁钢板合金镀层板制成的构件的服役寿命自然就会很长,一般情况下,可以达到30年以上。

3. Due to the super corrosion resistance of 10-20 times of the ordinary hot dip galvanized sheet and the corrosion resistance and self-healing effect of the cutting section, the service life of the members made of the hot dip galvanized aluminum and magnesium steel plate alloy plating sheet will naturally be very long. Generally, under normal circumstances, it can reach more than 30 years.

镀锌铝镁钢板具有独到的耐腐蚀性能,特别是切口保护性能。分为未发生划伤的平面情况和有切口、划伤的两种情况来分析。

1、Galvanized aluminum magnesium steel plate has a unique corrosion resistance performance, especially the incision protection performance.Divided into the plane situation without scratch and two situations with incision and scratch to analyze.

1.当镀锌铝镁钢板表面没有划伤时

1.When the surface of galvanized aluminum and magnesium steel plate is not scratched

镀层中所含的镁和铝的共同作用,会在长期的使用中在镀层的表面产生附着性极高的致密的氧化保护膜,将镀层与外部的腐蚀环境隔离开来,发挥隔离防腐的作用,防止镀层产生腐蚀。镁是比铝更活泼的金属,在空气中极其容易被氧化,固态镁形成的氧化膜也较致密,能有效地保护内部的组织,防止进一步被氧化。由于镁与铝不一样,在镀层中均匀而微细的分布,就使得氧化膜布满了整个镀层表面,使镀层中所有的组织都得到保护。

The combined action of magnesium and aluminum contained in the coating will produce a highly attached dense oxidation protective film on the surface of the coating in the long-term use, isolate the coating from the external corrosion environment, play the role of isolation and anticorrosion, and prevent the corrosion of the coating.Magnesium is a more lively metal than aluminum, which is extremely easy to be oxidized in the air. The oxide film formed by solid magnesium is also more compact, which can effectively protect the internal tissue and prevent further oxidation.Because magnesium is different from aluminum, the uniform and fine distribution in the coating layer makes the oxide film covers the whole coating surface, so that all the tissues in the coating are protected.

2、当镀层被划伤或有切口时

2. When the coating is cut or cut

从镀层中溶化出来的镁能在切口断面生成细致的含镁的致密的氧化膜,将划伤或切口部位裸露出的钢基覆盖起来,从而提高其耐蚀性。在这种情况下,锌的牺牲防腐和铝、镁的隔离防腐作用同样能发挥出来。在此基础上,由于镁十分活泼,能将钢板表面疏松的氧化物还原,置换成镁致密的氧化物,从而使裸露的钢基得到保护。

The magnesium dissolved from the coating can generate a detailed dense oxide film containing magnesium in the incision section, covering the exposed steel base from the scratch or incision site, thus improving its corrosion resistance.In this case, the sacrifice of zinc and the isolation of aluminum and magnesium can also be played.On this basis, because magnesium is very lively, it can reduce the loose oxide on the steel plate surface and replace the magnesium with dense oxide, so that the exposed steel base is protected.

锌铝镁钢板的应用:

Application of zinc, aluminum and magnesium steel plate:

(1)在室外长期使用的场合,比如高速护栏,要求产品规格较厚、表面镀层厚,以前不得不采用批量镀锌的方法,而锌铝镁诞生以后,就可以采用连续热镀锌铝镁的方法,这样的产品还有太阳能设备支架、桥梁构件等等;

(1) In outdoor long-term use of occasions, such as high-speed guardrail, requiring thick product specifications, thick surface coating, before had to use batch galvanized method, and zinc aluminum magnesium after the birth, you can use continuous hot galvanized aluminum magnesium method, such products and solar equipment support, bridge components and so on;

2)欧洲等地公路需要撒盐的场合,如果采用其它镀层生产汽车底板的话,就会很快被腐蚀掉,必须采用锌铝镁板来制造,这样的案例还有海滨别墅等建筑;

(2) Europe and other places of roads need salt occasions, if other coating is used to produce the car floor, it will be quickly corroded, must use zinc aluminum magnesium plate to make, such cases are seaside villas and other buildings;

3)需要耐酸的特殊场合,比如农场的禽舍、食槽,禽类粪便是酸性的,必须采用更耐酸洗腐蚀的锌铝镁板。

(3) Special occasions that need acid resistance, such as farm poultry houses, trough, poultry excrement is acid, must be more resistant to pickling corrosion of zinc aluminum magnesium plate.
