防火涂层

本文将膨胀型防火涂层应用于其表面，研究了防火涂层对WPC阻燃性能的影响。

The flame resistance of WPC was studied when intumescence fire-retardant coating was coated on its surface .

当防火涂层配方中阻燃体系四种组分的比例为120：10：20：8时，阻燃效果最佳。（4）阻燃体系的炭层的形成过程主要分为平稳阶段、炭化阶段和失炭阶段。

The property of flame retardant will be best when the four components in ratio of 120:10:20:8 . ( 4 ) The formation of carbon layer consists of stable stage , carbonization stage and loss of carbon phase .

经过使用观察，冷凝水已明显减少，防腐与防火涂层状态良好，消除了结构不安全的隐患，完全达到了工程整改与修复的目的。

After observation , condensed water decreases obviously , while both anticorrosive coating and damp-proof course work well , and the structure 's hidden danger has been removed , thus the project 's repair and renovation achieve the goal completely .

首先提出了定量表征混凝土受火爆裂程度的方法，然后研究了4种纤维、1种聚合物乳液和2种防火涂层对硅灰高强混凝土和粉煤灰高强混凝土受火爆裂的抑制效果。

A quantitative method on concrete spalling degree under fire was proposed . The spalling restrain efforts on silica fume high strength concrete and fly ash high strength concrete blended with four kinds fiber , one polymer latex and coated with two fireproofing were study .

由于近年来地铁内饰的防火涂层多采用有机涂料，但火灾发生时，高温浓烟易于积聚，造成重大人员伤亡和经济损失，所以地铁的防火要求在不断提高。

Considering the organic dope is mostly used for the inner decoration in metro systems , whereas Heavy smoke with high temperature will easily be accumulated to cause the severe personnel casualty and the economic loss , thus the requirement for fire protection in metro systems is continuously increasing .

有机膨胀型钢结构防火涂料缺点是涂层中有机物易分解，且遇火时释出有毒物质。

The organic dilatational fireproof coating for steelstrictures has the disadvantages of easy decomposition of organic structures to evolve toxic materials .

讨论了钢架结构的防火，并且制定涂层的设计方案、施工工艺及质量验收标准等。

The fire protection of steel structure was discussed . The design of coating and standards for the inspection and acceptance of coating application process and quality were developed .

耐火试验结果表明，采用50mm厚防火涂料全截面保护的碳纤维加固梁的耐火极限超过了2.5h，防火涂层中增设钢丝网片对约束防火涂层、防止开裂和脱落效果明显。

The experimental results show that the specimen insulated with 50 mm layer of coating can achieve a fire resistance rating of 2.5 hours , and the steel wire mesh embedded in insulated layer can effectively prevent the layer from cracking and dropping under fire .
