环境对彩涂板应用影响

Does the environment have any impact on the color coating board application?

是的。请听小编具体分析:

yes. Please listen to xiaobian specific analysis:

一、自然环境的影响(不同地区)

1. Influence of the natural environment (different regions)

不同地区彩涂钢板的选择主要考虑的是当地的风雪载荷以及腐蚀环境。风雪载荷主要是考虑建筑物的安全系数,这尽管和彩涂钢板的力学性能有关,但更多的和压型钢板的板形、厚度以及板与板之间的连接有关。而定量描述一个地区的腐蚀环境相对困难,影响彩涂钢板的腐蚀因素有很多。如:温度、湿度、昼夜温差、日照时间和日照强度、降雨量和降雨的酸度、风向和风速、腐蚀性沉降物等。

The choice of color coated steel plate in different areas is mainly based on the local snow load and corrosion environment. The snow load mainly considers the safety factor of the building, which is related to the mechanical properties of the color coated steel plate, but it is more related to the shape and thickness of the pressed steel plate and the connection between the plate and the plate. However, it is relatively difficult to quantitatively describe the corrosion environment in an area, and there are many corrosion factors affecting the color-coated steel plate. Such as: temperature, humidity, temperature difference between day and night, sunshine time and sunshine intensity, the acidity of rainfall and rainfall, wind direction and wind speed, corrosive settlement, etc.

● 彩涂钢板抗腐蚀影响的要素

它们分别为涂料种类、涂料厚度、涂料供应商、镀层种类、镀层厚度、预处理种类、钢板厚度、涂层结构等。

The elements of corrosion resistance of color-coated steel plate

They are coating type, coating thickness, coating supplier, coating type, coating thickness, pretreatment type, steel plate thickness, coating structure and so on.

● 施工设计对腐蚀的影响

安装或加工质量:它主要体现在加工时涂层是否损坏,是否在低温下涂层脆性时加工,安装时拖动钢板导致损伤,安装时结构焊接铁屑掉落在涂层上,施工完毕不对屋面板进行清扫等,这样都会引起材料的腐蚀。

Effect of construction design on corrosion

Installation or processing quality: it is mainly reflected in whether the coating is damaged during processing, whether the coating is brittle at low temperature, dragging steel plate during installation, structural welding iron chips fall on the coating during installation, and no cleaning after the construction, which will cause the corrosion of materials.

从上面这么多对彩涂钢板腐蚀因素的介绍,以及我们用户使用情况反馈和暴晒试验结果分析,我们对不同地区的使用建议如下:

From the above introduction of the corrosion factors of color coated steel plate, as well as the feedback of our users and the analysis of the exposure test results, our suggestions for different regions are as follows:

在紫外线强烈的高原(西南和西北)和低纬度地区(广东及以南地区)考虑彩涂钢板应该选择耐久性优越的涂层(PVDF涂层、HDP涂层、SMP涂层等),在高温高湿地区(南方沿海大部分地方)涂层及镀层都要选择耐腐蚀优越的材料,镀层厚度和涂层厚度至少要达到国家标准要求。

In the ultraviolet intense plateau (southwest and northwest) and low latitude area (Guangdong and south) consider color coating steel plate should choose superior durability coating (PVDF coating, HDP coating, SMP coating, etc.), in high temperature and high humidity area (most of the southern coastal areas) coating and coating to choose corrosion resistance materials, coating thickness and coating thickness at least to meet the national standards.

在海边使用彩涂钢板,需要厚涂层的彩涂钢板或者涂层相对致密的涂料品种,因为海水中的氯离子渗透能力很强,它能透过薄涂层或者不致密的涂层直接腐蚀基体镀层,当然,基板必须是镀锌或镀铝锌材料。在海水能溅到的地方,不建议采用彩涂钢板。

The use of color coated steel plate in the seaside, the need for thick coating color coated steel plate or coating relatively dense coating varieties, because the seawater chloride ion penetration ability is very strong, it can through the thin coating or not dense coating directly corrosion substrate coating, of course, the substrate must be galvanized or aluminum zinc material. Color-coated steel plate is not recommended where the sea can splash.

在工业性环境中,对彩涂的影响主要是酸雨,这些区域集中在湖南、重庆、江西等一带,联系采用高锌层镀锌基板的彩涂,彩涂层还是要求厚而致密。在其他不属于上述地区,用彩涂钢板的选择余地就比较大,只要符合彩涂国家标准就可以了。

In the industrial environment, the impact of the color coating is mainly acid rain, these areas are concentrated in Hunan, Chongqing, Jiangxi and other areas, contact with the use of high zinc layer galvanized substrate color coating, color coating or requirements thick and dense. In other do not belong to the above areas, with the choice of color coated steel plate is relatively large, want only to accord with the color coated national standard is ok.

二、使用环境的影响(不同行业)

2. Impact of use environment (different industries)

三、不同行业对彩涂钢板的使用分两方面来分析,其一就是彩涂钢板的外板,正常情况下就按不同地区选择就行了,但也要考虑小环境的影响,即是否在附近有腐蚀介质落到厂房围护结构上,如烧锅炉排放的气体、二氧化硫灰尘等,这在设计时应该考虑烟囱的高度和当地的主要风向等。另外,还有就是厂房密封性如何,也有可能厂房内高温高湿

3. Different industries for the use of color coated steel plate two aspects to analysis, one is the color coated steel plate, under normal circumstances just choose in different areas, but also want to consider the influence of the small environment, namely whether nearby corrosion medium fell to the plant envelope, such as burning boiler emissions, sulfur dioxide dust, etc., this in the design should consider the height of the chimney and the local main wind direction, etc. In addition, there is how the plant sealing, there may be high temperature in the plant high humidity.

带腐蚀性的气体冒出来在室外遇冷空气从而在彩涂钢板上结露,这种现象要避免,它会加速局部腐蚀的产生;其二是考虑彩涂钢板的内板(双层复合钢板)或背面漆(单层板)。这里要说明的就是相对来说屋面内板比墙面内板更容易腐蚀,如果工人能在该环境下工作,使用彩涂钢板是可以的。但室内环境的好坏或环保装置的投入会直接影响到彩涂钢板的使用寿命。

With corrosive gas out in the outdoor cold air and then on the color coated steel plate condensation, this phenomenon should be avoided, it will accelerate the generation of local corrosion; the second is to consider the inner plate (double composite steel plate) or back paint (single plate). It should be explained here that the roof plate is more likely to corrode than the wall plate. If the workers can work in this environment, it is possible to use color-coated steel plate. But the quality of indoor environment or the input of environmental protection device will directly affect the service life of color coated steel plate.

有色金属冶炼厂(铜、锌、铝、铅等)是最挑战彩涂钢板使用年限的。但是合理的选择材料、设计、以及环保投入等能保证或提高彩涂钢板的使用寿命。10年进行更换或维护是能做到的。钢铁厂、发电厂等也会产生腐蚀性的介质,但彩涂钢板都有长时间使用的经验。机械制造业(汽车、汽轮机、机床等)基本上不会对彩涂腐蚀带来负面影响,但要注意这些行业可能有热处理炉、锅炉等也会影响到局部环境,处理不好会带来彩涂钢板的腐蚀,尤其在加工损伤处或切边处。

Non-ferrous metal smelters (copper, zinc, aluminum, lead, etc.) are the most challenging ones to use the service life of color-coated steel plates. But the reasonable selection of materials, design, and environmental protection input can guarantee or improve the service life of color coated steel plate.10 years of replacement or maintenance can be done. Steel mills, power plants and other will also produce corrosive media, but color coated steel plates have a long time to use experience. Machinery manufacturing industry (automobile, steam turbine, machine tools, etc.) basically will not bring negative impact on color coating corrosion, but it should be noted that these industries may have heat treatment furnaces, boilers, etc., will also affect the local environment, poor treatment will bring color coating steel plate corrosion, especially in the processing damage or cutting edge.

仓储物流这个行业发展较快,使用轻钢也较多,本身不对彩涂板产生腐蚀,它对彩涂钢板的选择主要考虑大环境的影响,一般这样的工程都集中在工业发达及交通繁忙的地方,也就是工业环境以及沿海地区。

Warehousing and logistics industry is developing rapidly, the use of light steel is also the most, itself does not corrode the color steel plate, its choice of color steel steel plate mainly considers the impact of the environment, generally such projects are concentrated in the industrial developed and busy traffic places, that is, the industrial environment and coastal areas.

公用及民用建筑美观、经久耐用是彩涂钢板首要考虑的因素。因此,涂层抗变色、抗粉化以及涂层表面完整细腻就相当重要。公用及民用建筑关注的人多,且近距离,因此,涂料选择一般采用PVDFHDP,并且多选择浅颜色。

The beauty and durability of public and civil buildings are the primary considerations of color-coated steel plate. Therefore, the coating anti-color change, anti-powder and complete coating surface is very important. Public and civil buildings pay attention to many people, and close up, therefore, the choice of paint generally use PVDF or HDP, and choose more light colors.
