热浸锌桥架与热镀锌桥架有什么不同?

热浸锌桥架即热浸镀锌桥架,作为一种有效的金属防腐方式,已被广泛用于各行业的金属结构设施上。热浸锌是将除锈后的钢构件浸入800℃左右高温融化的锌液中,使钢构件表面附着锌层,锌层厚度对5mm以下薄板不得小于65μm,对厚板不小于86μm。从而起到防腐蚀的目的。

Hot dip galvanized cable tray, also known as hot-dip galvanized cable tray, is an effective metal anti-corrosion method and has been widely used in metal structural facilities in various industries. Hot dip galvanizing is the process of immersing derusted steel components in a molten zinc solution that melts at a high temperature of around 800 ℃, causing a zinc layer to adhere to the surface of the steel components. The thickness of the zinc layer should not be less than 65 for thin plates below 5mm μ m. For thick plates, not less than 86 μ M. So as to achieve the purpose of corrosion prevention.

热浸锌桥架特点:

Features of hot-dip zinc bridge:

1.整个热浸锌桥架表面均受到保护,无论在凹陷处管件内部,或任何其它涂层很难进入的角落,溶化锌均很容易均匀的覆盖上。

1. The entire surface of the hot-dip galvanized cable tray is protected, and the dissolved zinc is easily and evenly covered, whether inside the recessed pipe fittings or in any corners where it is difficult for other coatings to enter.

2.热浸锌桥架的镀锌层硬度值比钢材还大。其抗冲击及抗磨耗性均相当良好。

The hardness value of the galvanized layer on the hot-dip galvanized bridge is greater than that of steel. Its resistance to impact and wear is quite good.

3.热浸锌桥架在边角区,锌层往往比其它地方还厚,且有良好的韧性及抗磨耗性。而其它涂层在此边角处,往往是不易施工,易受伤害处,故常须再维护。

3. In the edge and corner areas of hot-dip galvanized cable trays, the zinc layer is often thicker than other areas, and has good toughness and wear resistance. And other coatings at this corner are often difficult to apply and vulnerable, so they often need to be maintained again.

4.即使因受很大的机械伤害或其它原因。造成一小部份的锌层脱落,将铁基裸露,此时,周围锌层就会发挥牺牲的功能,来保护此处钢铁,使其不受侵蚀。而其它涂层则刚好相反,锈会马上生成,且迅速漫延涂层下面,引起涂层剥落。

4. Even if subjected to significant mechanical injury or other reasons. Causing a small part of the zinc layer to fall off and exposing the iron base, the surrounding zinc layer will play a sacrificial role in protecting the steel here from erosion. On the other hand, the opposite is true for other coatings. Rust will immediately form and quickly spread below the coating, causing it to peel off.

5.热浸锌桥架的锌层在大气中的消耗是非常缓慢的,约为钢铁腐蚀速率的1/171/18,且是可预估的,其寿命远超过其它任何涂层。

The consumption of the zinc layer on hot-dip galvanized bridge frames in the atmosphere is very slow, about 1/17 to 1/18 of the corrosion rate of steel, and it is predictable, with a lifespan far exceeding that of any other coating.

6.热浸锌桥架寿命在某一特定的环境下,主要视镀层厚度而定。而镀层厚度又受钢铁厚度而决定,即越厚的钢铁易得较厚的镀层,故同一个钢构中厚的钢铁部位一定也得到较厚的镀层,以保证得到更长的寿命。

6. The lifespan of hot-dip galvanized cable trays is mainly determined by the thickness of the coating in a specific environment. The thickness of the coating is determined by the thickness of the steel, that is, the thicker the steel, the easier it is to obtain a thicker coating. Therefore, thicker steel parts in the same steel structure must also receive a thicker coating to ensure a longer lifespan.

7.因美观、艺术,或在特定严重腐蚀环境使用时,镀锌层可再施以上漆处理duplex system,只要漆的系统选用正确、施工容易,其防蚀效果比单独上漆及热浸锌寿命加起来还要好上1.5~2.5倍。

7. Due to its aesthetic and artistic appearance, or when used in specific severely corrosive environments, the galvanized layer can be further coated with a duplex system. As long as the paint system is selected correctly and easy to apply, its anti-corrosion effect is 1.5-2.5 times better than the combined lifespan of individual painting and hot-dip galvanizing.

8.热浸锌桥架使用广、防蚀效果好且经济效益佳。

8. Hot dip galvanized cable trays are widely used, have good anti-corrosion effects, and have good economic benefits.
