佛山彩钢板厂家供应猪棚养殖场畜牧业用PVDF氟碳涂层哑光白色彩涂板 ...

猪棚养殖场畜牧业对彩色涂层钢板涂层的选择要考虑的因素很多，它主要包括涂层种类、涂层厚度、涂层颜色和涂层光泽度。另外，有时侯还要考虑涂层的底漆和背面涂层的要求。

There are many factors to consider in the choice of color coated steel plate coating, which mainly includes coating type, coating thickness, coating color and coating gloss.In addition, sometimes you also consider the coating primer and the requirements of the back coating.

目前用于彩色涂层钢板的涂层有聚酯涂层（PE）、氟碳涂层（PVDF）、硅改性涂层（SMP）、高耐侯涂层（HDP）等。

Currently used for color coating steel plates are polyester coating (PE), fluorocarbon coating (PVDF), silicon modified coating (SMP), high hou tolerance coating (HDP), etc.

硅改性聚酯（SMP)

由于聚酯含有活性基-OH/-COOH，极易和其它高分子化和物反应，为改良PE的耐阳光性与粉化性，以色泽保持性与耐热性优的Silicone树脂作变性反应，和PE的变性比可于5%—50%之间，SMP提供钢板更好的持久性，其防蚀年限可长达10-12年，当然其价格也比较PE为高，但因Silicone树脂对材质的附着性和加工成型性并不理想，因此SMP彩涂钢板并不适用于需多次成型加工的场合，大部分用于建筑屋顶及外墙。

Silicon-modified polyester (SMP)

Since the polyester contains the active group-OH / -COOH, Easy to react with other polymermers and objects, To improve the sunshine resistance and powder properties of PE, Using Silicone resin with excellent color retention and heat resistance, The denaturation ratio to the PE is between 5% and 50%, SMP provides better durability, Its corrosion prevention life can be up to 10-12 years, Of course, its price is also higher than the PE, However, because the attachment and processing and molding of Silicone resin are not ideal, Therefore, the SMP color-coated steel plate is not suitable for multiple molding and processing occasions, Most of it is used for the building roof and exterior walls.

高耐侯聚酯(HDP)

对于PE和SMP的缺点，耐候性HDP聚酯涂料，且优于普通的硅改性聚酯涂料，其户外耐候性达到15年。高耐候聚酯树脂在合成时采用含环己烷结构的单体，来达到树脂的柔韧性、耐候性和成本的平衡，采用不含芳香族的多元醇和多元酸来减少树脂对UV光线的吸收，达到涂料的高耐候性能。涂料配方中加入紫外线吸收剂和位阻胺（HALS）提高漆膜耐候性能。高耐候聚酯卷材涂料的性价比十分高。

High tolerance polyester (HDP)

For the disadvantages of PE and SMP, weather-resistant HDP polyester coatings, and better than ordinary silicon modified polyester coatings, its outdoor weather resistance reaches 15 years.High weather resistance polyester resin uses monomer containing cyclohexane structure to achieve the balance of flexibility, weather resistance and cost of resin, using no aromatic polyols and polyacid to reduce the absorption of resin to UV light, to achieve the high weather resistance of coating.UV absorbent and bitamine (HALS) are added to improve the weather resistance of paint film.High weather resistance polyester coil coating is very effective.

聚酯(PE)

PE涂料对于材质有良好的附着性，彩涂钢板易于加工成型，价格低廉且产品多，颜色和光泽的选择余地大。聚酯涂料对耐紫外光性与涂膜耐粉化性，但并不理想，因此PE涂料  的使用仍需受到一些限制，一般用在空气污染不严重的地区或需多次成型加工的产品。

polyester (PE)

PE coating has a good attachment to the material, color coated steel plate is easy to process and shape, low price and many products, color and gloss choice is large.Polester coating to UV resistance and film powder resistance, but not ideal, so the use of PE coating still needs to be subject to some restrictions, generally used in the air pollution is not serious areas or need multiple molding processing products.

氟碳涂层PVDF

由于PVDF的化学键与化学键间，有很强的键能，因此涂料具有非常好的防蚀性和色泽保持性，在建筑工业用彩涂钢板涂料中，是属于最高级产品，且分子量大又为直键型结构，因此除耐化学药品性之外，机械性能、耐紫外线和耐热性能也很突出。在一般环境下，其防蚀年限可达20—25年之久。近年来，国内开始盛行以三氟氯乙烯和乙烯酯单体共聚的含氟树脂，大量应用于建筑的外墙和金属板，由于使用易水解的乙烯酯单体和氟的含量较PVDF低30%左右，因此其耐候性与PVDF比较，有一定的差距。宝钢所生产的氟碳涂层，其涂层PVDF含量不小于70%（其他为丙稀酸树脂）。

Fluorocarbon-coated PVDF

Due to PVDF bond and chemical bonds, has a strong bond energy, so the coating has very good corrosion resistance and color retention, in the construction industry with color coated steel paint, is the highest product, and large molecular weight and direct bond structure, so in addition to chemical resistance, mechanical performance, ultraviolet resistance and heat resistance is also very outstanding.In the general environment, its corrosion protection life can be up to 20-25 years.In recent years, fluorine-containing resin with trifluorinated vinyl chloride and vinyl ester monomer began to prevail in China, which is widely used in the external wall and metal plate of buildings. Because the content of vinyl ester monomer and fluorine is about 30% lower than that of PVDF, there is a certain gap in its weather resistance compared with PVDF.Fluorocarbon coating produced by Baosteel, its coating PVDF content is not less than 70% (other is propionacid resin).
