在建筑材料領(lǐng)域，彩鋼復(fù)合板憑借出色性能，成為各類建筑的理想之選。禹城作為該板材重要產(chǎn)地，產(chǎn)品憑借可靠質(zhì)量和豐富類型，備受市場(chǎng)關(guān)注。下面，一起深入了解其材質(zhì)構(gòu)成。

In the field of building materials, color steel composite panels have become an ideal choice for various types of buildings due to their excellent performance. Yucheng, as an important production area for this board, has attracted market attention for its reliable quality and diverse types of products. Next, let's delve into its material composition together.

一、基板：堅(jiān)實(shí)的根基

1、 Substrate: A solid foundation

禹城彩鋼復(fù)合板基板多采用熱鍍鋅或鍍鋁鋅鋼板。熱鍍鋅鋼板以 Q235 或 Q345 鋼材為基材，鍍鋅量每不低于 80 克，能隔絕氧氣與水分，延緩銹蝕。鍍鋁鋅鋼板表面鍍覆 55% 鋁、43.4% 鋅與 1.6% 硅組成的合金鍍層，不僅耐腐蝕性佳，耐熱性也更突出。

Yucheng color steel composite board substrates often use high-quality hot-dip galvanized or aluminum zinc coated steel plates. Hot dip galvanized steel sheet is made of Q235 or Q345 steel as the substrate, with a galvanizing amount of not less than 80 grams per square meter, which can isolate oxygen and moisture and delay corrosion. The surface of aluminum zinc coated steel plate is coated with an alloy coating composed of 55% aluminum, 43.4% zinc, and 1.6% silicon, which not only has good corrosion resistance but also outstanding heat resistance.

二、涂層：賦予外觀與防護(hù)

2、 Coating: endowing appearance and protection

在基板上，禹城彩鋼復(fù)合板涂有聚酯（PE）、硅改性聚酯（SMP）、氟碳（PVDF）等功能性涂層。聚酯涂層色彩豐富、加工性好，戶外壽命 5 - 8 年，成本低，多用于一般工業(yè)建筑。硅改性聚酯涂層加入硅氧烷，提升了硬度與耐候性，戶外壽命 8 - 15 年，適用于商業(yè)建筑。氟碳涂層以聚偏氟乙烯樹(shù)脂為主，耐候、耐腐蝕且自潔性強(qiáng)，15 年以上不褪色，適用于高端建筑。

On the substrate, Yucheng color steel composite board is coated with functional coatings such as polyester (PE), silicon modified polyester (SMP), fluorocarbon (PVDF), etc. Polyester coating has rich colors, good processability, outdoor lifespan of 5-8 years, low cost, and is mostly used in general industrial buildings. Silicon modified polyester coating with added siloxane enhances hardness and weather resistance, with an outdoor lifespan of 8-15 years, suitable for commercial buildings. Fluorocarbon coating is mainly made of polyvinylidene fluoride resin, which is weather resistant, corrosion-resistant, and has strong self-cleaning properties. It will not fade for more than 15 years and is suitable for high-end buildings.

三、芯材：決定性能的關(guān)鍵

3、 Core material: the key to determining performance

1. 聚苯乙烯（EPS）芯材

1. Polystyrene (EPS) core material

EPS 芯材由可發(fā)性聚苯乙烯珠粒成型，質(zhì)輕、保溫佳，導(dǎo)熱系數(shù) 0.033W/(m?K)，成本低，多用于臨時(shí)建筑。但防火性能差，屬 B2 級(jí)可燃材料。

EPS core material is formed from expandable polystyrene beads, which is lightweight, has good insulation, a thermal conductivity of 0.033W/(m? K), low cost, and is commonly used in temporary buildings. But it has poor fire resistance and belongs to B2 level combustible materials.

2. 擠塑聚苯乙烯（XPS）芯材

2. Extruded polystyrene (XPS) core material

XPS 芯材通過(guò)擠出工藝制成，密度更高，導(dǎo)熱系數(shù)低 0.028W/(m?K)，抗壓性強(qiáng)，適用于對(duì)保溫和結(jié)構(gòu)強(qiáng)度要求高的建筑，如冷庫(kù)。不過(guò)較高，防火性能欠佳。

XPS core material is made through extrusion technology, with higher density and a thermal conductivity as low as 0.028W/(m? K). It has strong compressive strength and is suitable for buildings with high requirements for insulation and structural strength, such as cold storage. However, the price is high and the fire resistance is poor.

3. 聚氨酯（PU）芯材

3. Polyurethane (PU) core material

PU 芯材由異氰酸酯和多元醇發(fā)泡而成，導(dǎo)熱系數(shù) 0.024W/(m?K)，閉孔率超 95%，防水性好。經(jīng)特殊處理可達(dá) B1 級(jí)難燃標(biāo)準(zhǔn)，廣泛應(yīng)用于對(duì)保溫、防水和防火要求高的建筑。

PU core material is foamed with isocyanates and polyols, with a thermal conductivity of 0.024W/(m? K), a closed cell rate of over 95%, and good waterproof performance. After special treatment, it can reach the B1 level flame retardant standard and is widely used in buildings with high requirements for insulation, waterproofing, and fire prevention.

4. 巖棉和玻璃棉芯材

4. Rock wool and glass wool core materials

巖棉和玻璃棉屬無(wú)機(jī)纖維材料，不燃，防火等級(jí) A1 級(jí)。巖棉以玄武巖等為原料，玻璃棉以玻璃為原料。二者導(dǎo)熱系數(shù)分別為 0.040W/(m?K) 和 0.038W/(m?K)，保溫和吸音降噪效果好，常用于防火要求嚴(yán)格的建筑。

Rock wool and glass wool are inorganic fiber materials, non combustible, and have a fire rating of A1. Rock wool is made from basalt and other materials, while glass wool is made from glass. The thermal conductivity coefficients of the two are 0.040W/(m? K) and 0.038W/(m? K), respectively. They have good insulation, sound absorption and noise reduction effects, and are commonly used in buildings with strict fire protection requirements.

禹城彩鋼復(fù)合板材質(zhì)豐富，為不同建筑需求提供了多樣解決方案。選擇時(shí)，需綜合考慮建筑功能、環(huán)境和預(yù)算，以發(fā)揮其優(yōu)勢(shì)。
