環(huán)境對彩涂板應(yīng)用有影響嗎？

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

是的。請聽小編具體分析：

yes. Please listen to xiaobian specific analysis:

一、自然環(huán)境的影響（不同地區(qū)）

1. Influence of the natural environment (different regions)

不同地區(qū)彩涂鋼板的選擇主要考慮的是當?shù)氐娘L雪載荷以及腐蝕環(huán)境。風雪載荷主要是考慮建筑物的安全系數(shù)，這盡管和彩涂鋼板的力學性能有關(guān)，但更多的和壓型鋼板的板形、厚度以及板與板之間的連接有關(guān)。而定量描述一個地區(qū)的腐蝕環(huán)境相對困難，影響彩涂鋼板的腐蝕因素有很多。如:溫度、濕度、晝夜溫差、日照時間和日照強度、降雨量和降雨的酸度、風向和風速、腐蝕性沉降物等。

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.

● 彩涂鋼板抗腐蝕影響的要素

它們分別為涂料種類、涂料厚度、涂料供應(yīng)商、鍍層種類、鍍層厚度、預處理種類、鋼板厚度、涂層結(jié)構(gòu)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.

● 施工設(shè)計對腐蝕的影響

安裝或加工質(zhì)量：它主要體現(xiàn)在加工時涂層是否損壞，是否在低溫下涂層脆性時加工，安裝時拖動鋼板導致?lián)p傷，安裝時結(jié)構(gòu)焊接鐵屑掉落在涂層上，施工完畢不對屋面板進行清掃等，這樣都會引起材料的腐蝕。

● 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.

從上面這么多對彩涂鋼板腐蝕因素的介紹，以及我們用戶使用情況反饋和暴曬試驗結(jié)果分析，我們對不同地區(qū)的使用建議如下：

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:

在紫外線強烈的高原（西南和西北）和低緯度地區(qū)（廣東及以南地區(qū)）考慮彩涂鋼板應(yīng)該選擇耐久性優(yōu)越的涂層（PVDF涂層、HDP涂層、SMP涂層等），在高溫高濕地區(qū)（南方沿海大部分地方）涂層及鍍層都要選擇耐腐蝕優(yōu)越的材料，鍍層厚度和涂層厚度至少要達到國家標準要求。

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.

在海邊使用彩涂鋼板，需要厚涂層的彩涂鋼板或者涂層相對致密的涂料品種，因為海水中的氯離子滲透能力很強，它能透過薄涂層或者不致密的涂層直接腐蝕基體鍍層，當然，基板必須是鍍鋅或鍍鋁鋅材料。在海水能濺到的地方，不建議采用彩涂鋼板。

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.

在工業(yè)性環(huán)境中，對彩涂的影響主要是酸雨，這些區(qū)域集中在湖南、重慶、江西等一帶，聯(lián)系采用高鋅層鍍鋅基板的彩涂，彩涂層還是要求厚而致密。在其他不屬于上述地區(qū)，用彩涂鋼板的選擇余地就比較大，只要符合彩涂國家標準就可以了。

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、使用環(huán)境的影響(不同行業(yè))

2. Impact of use environment (different industries)

三、不同行業(yè)對彩涂鋼板的使用分兩方面來分析，其一就是彩涂鋼板的外板，正常情況下就按不同地區(qū)選擇就行了，但也要考慮小環(huán)境的影響，即是否在附近有腐蝕介質(zhì)落到廠房圍護結(jié)構(gòu)上，如燒鍋爐排放的氣體、二氧化硫灰塵等，這在設(shè)計時應(yīng)該考慮煙囪的高度和當?shù)氐闹饕L向等。另外，還有就是廠房密封性如何，也有可能廠房內(nèi)高溫高濕。

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.

帶腐蝕性的氣體冒出來在室外遇冷空氣從而在彩涂鋼板上結(jié)露，這種現(xiàn)象要避免，它會加速局部腐蝕的產(chǎn)生；其二是考慮彩涂鋼板的內(nèi)板（雙層復合鋼板）或背面漆（單層板）。這里要說明的就是相對來說屋面內(nèi)板比墻面內(nèi)板更容易腐蝕，如果工人能在該環(huán)境下工作，使用彩涂鋼板是可以的。但室內(nèi)環(huán)境的好壞或環(huán)保裝置的投入會直接影響到彩涂鋼板的使用壽命。

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.

有色金屬冶煉廠（銅、鋅、鋁、鉛等）是最挑戰(zhàn)彩涂鋼板使用年限的。但是合理的選擇材料、設(shè)計、以及環(huán)保投入等能保證或提高彩涂鋼板的使用壽命。10年進行更換或維護是能做到的。鋼鐵廠、發(fā)電廠等也會產(chǎn)生腐蝕性的介質(zhì)，但彩涂鋼板都有長時間使用的經(jīng)驗。機械制造業(yè)（汽車、汽輪機、機床等）基本上不會對彩涂腐蝕帶來負面影響，但要注意這些行業(yè)可能有熱處理爐、鍋爐等也會影響到局部環(huán)境，處理不好會帶來彩涂鋼板的腐蝕，尤其在加工損傷處或切邊處。

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.

倉儲物流這個行業(yè)發(fā)展較快，使用輕鋼也較多，本身不對彩涂板產(chǎn)生腐蝕，它對彩涂鋼板的選擇主要考慮大環(huán)境的影響，一般這樣的工程都集中在工業(yè)發(fā)達及交通繁忙的地方，也就是工業(yè)環(huán)境以及沿海地區(qū)。

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.

公用及民用建筑美觀、經(jīng)久耐用是彩涂鋼板首要考慮的因素。因此，涂層抗變色、抗粉化以及涂層表面完整細膩就相當重要。公用及民用建筑關(guān)注的人多，且近距離，因此，涂料選擇一般采用PVDF或HDP，并且多選擇淺顏色。

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.
