PSPC是IMO关于新建船舶压载舱防护涂层性能标准

PSPC是IMO关于新建船舶压载舱防护涂层性能标准。

该标准包括涂料、涂层性能标准及造船涂装全过程质量控制要求两部分，要求海水压载舱防护涂层具有预期15年使用寿命，从防护涂层膜厚、涂装施工质量控制、防护涂层性能基本要求、涂层质量评定验收、涂层资格认可试验方法、设备等各环节进行全面控制。

该标准适用于2008年7月1日后签订建造合同、2009年1月1日开始建造及2012年交付使用的所有500吨以上船舶。

目前船舶压载舱涂层主要采用环氧类硬涂层涂装。

根据国外船舶涂料实验室的检测结果，厚膜环氧硬质涂层有良好的附着力和耐模拟摇摆试验舱加速试验性，PSCP将环氧压载舱涂料作为涂料类型加以规定。

相比我国标准，PSPC增加了冷凝试验、耐阴极保护性{HotT ag}、涂层柔韧性要求，且在涂层比重、附着力、与底漆配套等项目上作了更加细致的要求，尤其是耐盐雾、耐盐水、冷凝试验均要通过180天模拟舱试验严格检测。

将环氧压载舱涂料作为涂料类型加以规定，PSPC强制执行将对我国船舶制造成本、制造周期、资源消耗等带来重大影响，且涉及船舶业多方利益，船舶涂料供应商将承担更多责任和保证。

中国环氧树脂行业协会专家介绍表示，压载舱防护涂料在今后开发中，应首先满足附着力和耐模拟摇摆舱腐蚀试验要求，涂层应为硬干、致密状态。

针对PSPC对预处理钢板表面可溶性盐含量较严格的要求，准备压载舱涂料在不同表面盐含量时涂层抗起泡力的技术数据；目前环氧型压载舱涂层质地坚硬但脆性较大，应开发既符合附着力和耐腐蚀加速试验要求又具有一定耐冲击性的涂层。

据中国环氧树脂行业协会专家了解，一些船舶事故是由于压载舱腐蚀导致船体强度下降而造成，压载舱防护涂层是影响船舶安全运营的重要因素。

船舶压载舱保护涂料最大的威胁是在水下开裂，而这种开裂只有一种可能就是海水腐蚀，因此对压载舱进行防腐蚀涂装是非常重要的措施。

免受腐蚀困挠的压载舱能够保证船舶在海上安全行驶，延长船舶的使用寿命。

The terms used in this Guideline have the same meaning as those defined in PSPC.本指南中所引用的术语与PSPC中的定义相同。

These guidelines are developed based on the current available and approved types of paints and it isrecognised that new types of paint maybe developed in the future for which all these requirements maynot be appropriate. It is recognised in these guidelines but that any deviation from these requirements willbe specific to the paint being approved and form part of the testing and approved process to confirm theircompliance with the requirements of MSC.215(82) as amended.本指南是基于目前已被认可的涂料系统所提出的，这些要求对于将来开发出的新型涂料系统可能并不适用。

任何不是目前已被认可的涂料系统的其它涂料系统，需经检测试验认可，以证明该涂料系统符合MSC.215（82）提出的要求。
