濟(jì)南彩鋼瓦:彩鋼瓦的使用壽命是多久?

發(fā)布時(shí)間:2025-09-18 來(lái)源:http://www.95fjrc.com/

  彩鋼板的使用壽命包括兩方面:1.外觀的使用壽命? 2.功能使用壽命外觀使用壽命顧名思義,就是指的是涂層保持良好的外觀年限,也就是指漆膜的完整性和涂層粉化、褪色的年限。這主要與涂層的種類有關(guān),一般使用環(huán)境下,PE聚酯涂層,漆膜20個(gè),8-10年;HDP高耐候聚酯涂層,漆膜25個(gè),10-15年;PVDF氟碳涂層,漆膜25個(gè),20-25年。在紫外線照射強(qiáng)烈,大氣環(huán)境惡劣使用環(huán)境下,使用年限會(huì)相對(duì)縮短。功能使用壽命,指的是彩鋼板抗腐蝕能力和可使用壽命。這除了跟涂層種類、涂層厚度,鍍層種類、鍍層重量等,產(chǎn)品本身參數(shù)有關(guān)外,還與溫度、濕度、光照強(qiáng)度、大氣環(huán)境、腐蝕強(qiáng)度等外部使用環(huán)境有關(guān)系。所以,在承諾使用壽命時(shí),先確認(rèn)以上幾個(gè)方面的相關(guān)問(wèn)題。base64_image

  The service life of color steel plate includes two aspects: 1. The service life of appearance? 2. Function service life Appearance service life, as the name suggests, refers to the period of time that the coating maintains a good appearance, that is, the integrity of the paint film and the period of coating powdering and fading. This is mainly related to the type of coating. In general, for PE polyester coating, the paint film has 20 layers and lasts for 8-10 years; HDP high weather resistant polyester coating, 25 paint films, 10-15 years; PVDF fluorocarbon coating, 25 paint films, 20-25 years. Under strong ultraviolet radiation and harsh atmospheric conditions, the service life will be relatively shortened. Functional service life refers to the corrosion resistance and usable life of color steel plates. This is not only related to the type and thickness of the coating, the type and weight of the coating, as well as the parameters of the product itself, but also to external usage environments such as temperature, humidity, light intensity, atmospheric environment, and corrosion strength. So, when promising the service life, first confirm the relevant issues in the above aspects.
