由于太阳能路灯的灯杆须要合乎高分量的太阳能电池板,高扭力的风力,乃至有的工程须要将繁重的锂电池安置在灯灯杆上,假如灯杆出了成绩,那么有可能形成灯杆的扭裂或许是断裂乃至伤及财富跟职员。而热镀锌可能有效地保障灯杆不受腐化,在长达25年的时光内保障了太阳能路灯灯杆的畸形强度,有效地维护了它所承载的各个部件。
 
现在太阳能路灯灯杆的防腐方法有以下三种:
 
1、热镀锌防腐,当初太阳能路灯厂家抉择最多的也是最好的镀锌方法。
 
2、冷镀锌,防腐才能跟热镀锌比拟拟次一点。
 
3、喷漆,喷漆方法曾经很少人应用了,由于多少乎达不到室外的防腐才能。
 
热镀锌维护灯杆不被腐化的道理是什么呢烦忙学过化学的人都应当晓得“牺牲阳极”道理,锌是比铁活泼的金属元素,当锌-铁构成的联合物(锌-铁化合物)遭到腐蚀构成电极的时间,电子会向铁转移从而维护了铁,就义了锌元素。同时,锌在氛围中很轻易构成致密的氧化层,维护了锌免受更深的氧化。在氛围中,锌构成致密氧化物,避免更深的氧化;在电解质中(雨水、海水、河水、酸碱腐蚀)锌起到就义阳极感化,所以无论在哪种情形下,锌都市维护铁元素免受腐蚀。
 
Because the lamp poles of solar street lamps need to meet the high weight solar panels, high-torque wind power, and even some projects need to place heavy lithium batteries on the lamp poles. If the lamp poles are in trouble, It is possible to cause the lamp pole to crack or break or even injure property and personnel. Hot galvanizing can effectively ensure that the lamp poles are not corroded, and ensure the normal strength of the solar lamp poles for a period of up to 25 years, effectively protecting the various components it carries.
At present, there are three kinds of anti-corrosion methods for solar street lamp poles:
1, hot galvanizing corrosion, now solar street lamp manufacturers choose the most is also the best way to galvanize.
2, cold galvanizing, anti-corrosion ability compared with hot galvanizing the next point.
3, spray paint, spray paint has been used by very few people, because almost no outdoor anti-corrosion ability.
What is the principle of hot galvanized lamp pole protection from corrosion? Everyone who has studied chemistry should know the "sacrifice anode" principle. Zinc is an active metal element than iron. When the zinc-iron junction(zinc-iron compound) is eroded to form an electrode, Electrons transfer to iron to protect iron, sacrificing zinc. At the same time, zinc can easily form a dense oxide layer in the air, protecting zinc from deeper oxidation. In the air, zinc forms dense oxides that prevent deeper oxidation; In electrolytes(rainwater, seawater, river water, acid-base erosion) zinc acts at the expense of the anode, so in either case, zinc will protect the iron from erosion.
