氟碳彩涂使用寿命

天物彩板专注彩板定制16年——更多网状氟碳彩涂钢板_氟碳彩钢板使用年限请拨打网站上方电话咨询

由于使用极限的测量标准不统一,彩涂板的使用寿命概念也不统一。彩涂板的使用寿命通常包括两个方面,一是涂层的耐候性,二是彩涂板的整体防腐性能。


通过室外挂板在各种典型大气和腐蚀条件下的长期暴露试验,结合实验室模拟环境的加速耐候试验结果,对彩涂板的使用寿命进行了综合评价。
当然,这只是推测给定工况下的概率寿命,与施工中彩涂板的实际寿命还有一定差距。
聚偏氟乙烯是一种聚偏氟乙烯。氟原子最大的电负性形成一个非常稳定的氟碳键。聚偏氟乙烯具有独特的分子对称性,具有超强的稳定性、独特的抗紫外线光解性、优异的绝缘性和机械性能。
天物 PVDF氟碳涂层板采用美国PPG氟碳涂层,含Kynar 500 PVDF树脂。Kynar 500氟碳树脂含量大于70%,采用抗氧化性能稳定的无机陶瓷颜料。中性盐雾试验超过960小时,紫外线老化试验超过1800小时。具有优异的韧性、耐化学性、耐酸雨性和抗紫外线侵蚀性。同时,由于氟碳涂层具有优异的自清洁功能,在以后的使用过程中维护成本非常低。

根据以上数据估算,在正常使用条件下,胺类氟碳彩板的耐腐蚀性和耐褪色性可达到20-25年,漆膜完整性可达到40年以上。它非常适用于机场、高速火车站、体育馆等防褪色性能高的公共建筑,也适用于耐腐蚀性要求高的钢厂、电厂。工厂、化工、沿海等领域。

Because the criteria for measuring the use limit are not uniform, the concept of service life of color coated sheets can not be uniform. The service life of color coated panels usually includes two aspects, one is the weatherability of coatings, the other is the overall anticorrosion performance of color coated panels.
The service life of color coated panels is generally evaluated by long-term exposure test of outdoor hanging panels under various typical atmospheric and corrosive conditions, and combined with the results of accelerated climate resistance test of simulated environment in laboratory.
Of course, this is only to speculate the probabilistic life under the given working conditions, and there is still a certain gap between the actual life of color coated panels in construction.
PVDF is a kind of polyvinylidene fluoride. The largest electronegative property of fluorine atom forms a very stable fluorocarbon bond. With the unique symmetry of its molecule, PVDF has super stability, unique ultraviolet photolysis resistance, excellent insulation and mechanical properties.
 PVDF fluorocarbon coating plate is made of American PPG fluorocarbon coating containing Kynar 500 PVDF resin. Kynar 500 fluorocarbon resin content is more than 70%, and inorganic ceramic pigments with stable antioxidant performance are used. Its neutral salt spray resistance test is more than 960 hours, and ultraviolet aging test is more than 1800 hours. It has excellent toughness, chemical resistance, acid rain resistance and ultraviolet erosion resistance. At the same time, because of the excellent self-cleaning function of the fluorocarbon coating, the maintenance cost is very low in the later use process.
Based on the above data, it is estimated that under normal operating conditions, the corrosion resistance and fading resistance of Amina fluorocarbon color plate can reach 20-25 years, and the integrity of paint film can reach more than 40 years. It is very suitable for public buildings such as airports, high-speed railway stations, gymnasiums, etc. with high anti-fading performance, and for steel plants and electric power plants with high requirements for corrosion resistance. Factory, chemical industry, coastal and other fields.
