　　Abstract: water-based epoxy zinc phosphate primer and water-based epoxy zinc-rich primer are two with efficient antirust effect of anti-corrosion products, its characteristic and using the environment have certain similarities. So, for both product’s performance in different construction environment, what is difference between them?

　　【水性环氧磷酸锌底漆】与【水性环氧富锌底漆】的相同点

　　Waterborne epoxy zinc phosphate primer with 】 【 water-based epoxy zinc-rich primer 】 similarities

　　两者都属于环氧树脂类的环氧底漆产品，具有极强的防腐防锈效果，漆膜坚韧，附着力强。兼具耐碱、耐潮湿、耐溶剂等特点

　　两者都属于环氧树脂类的环氧底漆产品，具有极强的防腐防锈效果，漆膜坚韧，附着力强。兼具耐碱、耐潮湿、耐溶剂等特点

　　【水性环氧磷酸锌底漆】与【水性环氧富锌底漆】的四大差异

　　Waterborne epoxy zinc phosphate primer with 】 【 water-based epoxy zinc-rich primer 】 the four big differences

　　1. 防锈颜料不同导致防锈能力不同：

　　1. The antirust paint different lead to rust resistance:

　　水性环氧富锌底漆以锌粉为主要颜料，锌粉含量能够达到60％——80％之间，因此它具有阴极保护、暖蚀和屏蔽的三重防锈能力。这样的效果，锌粉能够咸鱼钢铁受到腐蚀，产生络合物，也就起到了屏蔽缓蚀不生锈的作用。

　　Water-based epoxy zinc-rich primer zinc powder as the main pigment, zinc powder content can reach 60% - 80%, therefore it has the cathodic protection, warming triple rust resistance corrosion and shielding. Such effect, zinc powder can be salted fish steel from corrosion, produce complex, also have the effect of the shielding corrosion rusty.

　　水性环氧磷酸锌底漆主要以磷酸锌为主要防锈颜料，磷酸锌防锈原理是通过水解反应生成的附着和阻蚀络合物，可使金属底材表面磷化，形成在阳极范围内特别有效的保护层，起到良好的缓蚀和屏蔽效果，隔绝腐蚀介质的侵蚀。

　　Waterborne epoxy zinc phosphate primer mainly zinc phosphate as the main antirust pigment, zinc phosphate antirust principle is through the hydrolysis reaction of adhesion and corrosion resistance complex, can make the metal substrate surface phosphating, form within the scope of the anode particularly effective protective layer, have good corrosion and shielding effect, isolation of erosion corrosion medium.

　　2. 表面处理不同

　　2. The different surface treatment

　　水性环氧富锌底漆对底材的处理行对严格一些，必须喷砂处理达到除锈等级标准Sa2.5级以上。

　　水性环氧磷酸锌底漆对底材要求略低一些，只要底材处理干净即可，确保无铁锈、氧化皮和油污等。

　　Water-based epoxy zinc-rich primer to substrate processing line to some strict, must sandblasting derusting grades standard Sa2.5 level or above.

　　Waterborne epoxy zinc phosphate primer on substrate is slightly lower, as long as the substrate processing clean, make sure no rust, scale, oil, etc.

　　3. 应用环境不同

　　3. The different application environment

　　水性环氧富锌底漆适用于大气环境下的钢结构防腐涂装，油漆是环境相对恶劣的海洋设施、港口设施，机械设备等。

　　水性环氧磷酸锌底漆适用于大气环境下普通的机械设备、储罐工程何管道防腐涂装。

　　Water-borne epoxy zinc-rich primer for steel structure anticorrosion coating of the atmospheric environment, the paint is relatively tough Marine environment facilities, port facilities, machinery and equipment, etc.

　　Waterborne epoxy zinc phosphate primer applied to atmospheric environment common mechanical equipment, storage tank engineering pipeline anticorrosion coating.

　　4. 配套方案不同

　　4. Supporting scheme

　　水性环氧富锌底漆一般均与中间漆和面漆配套使用。而水性环氧磷酸锌底漆一般直接与面漆配套使用就可以。

　　Water-borne epoxy zinc-rich primer and intermediate paint commonly it is used together with finish paint. The waterborne epoxy zinc phosphate primer generally with paint can directly.
