涂層鋼板具有輕質(zhì)、美觀和良好的防腐蝕性能，又可直接加工，它給建筑業(yè)、造船業(yè)、車輛制造業(yè)、家具行業(yè)、電氣行業(yè) 等提供了一種新型原材料，起到了以鋼代木、高效施工、節(jié)約能源、防止污染等良好效果。使用鍍鋅鋼板為基板的彩色涂 層鋼板，除有鋅保護(hù)外，鋅層上的有機(jī)涂層起了覆蓋隔離作用，可防止鋼板生銹，使用壽命比鍍鋅鋼板更長，據(jù)介紹涂層鋼板的使用壽命比鍍鋅鋼板長50%。 但是，在不同的地區(qū)和不同的使用部位，采用相同鍍鋅量、同種涂料、相同涂層厚度的彩色涂層板，其使用壽命會(huì)有很大的不同。例如，在工業(yè)區(qū)或沿海地區(qū)，由于受到空氣中二氧化硫氣體或鹽分的作用，腐蝕速度加快，使用壽命受到影響。在雨季，涂層長期受雨水浸濕、或者在日夜溫差太大易結(jié)露的部位，都會(huì)較快地受到腐蝕，使用壽命均會(huì)降低。 用彩色涂層鋼板制造的建筑物或廠房，經(jīng)常受到雨水沖洗時(shí)使用壽命較長，否則，由于受二氧化硫氣體、鹽和灰塵的作用而影響使用。因此，在設(shè)計(jì)時(shí)，若屋頂?shù)膬A斜度越大，則越不容易積聚灰塵等污物，使用壽命越長；對于那些不受雨水經(jīng) 常沖洗的區(qū)域或部位，應(yīng)定期用水沖洗 。

Coated steel plate has light, beautiful and good corrosion prevention properties, and can be processed directly again. It provides a new raw material for construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry, and plays a good effect of substituting steel for wood, efficient construction, energy saving, pollution prevention and so on. The use of galvanized steel plate as the substrate color coated steel plate, in addition to zinc protection, the organic coating on the zinc layer plays a cover isolation effect, can prevent steel plate rust, the service life is longer than galvanized steel plate, according to the introduction of the service life of coated steel plate is 50% longer than that of galvanized steel plate. However, in different areas and different parts, the use of the same galvanized amount, the same coating, the same coating thickness of the color coating plate, its service life will be very different. For example, in industrial or coastal areas, the corrosion rate is affected by the action of sulfur dioxide gas or salt in the air. In the rainy season, the coating is wet by rain for a long time, or when the temperature difference between day and night is too large and easy to condense, it will be corroded quickly, and the service life will be reduced. Buildings or factories made with color-coated steel plates often have a long service life when washed by rainwater, otherwise, they will be affected by the action of sulfur dioxide gas, salt and dust. Therefore, in the design, if the tilt of the roof, the more it is less likely to accumulate dust and other dirt, the longer the service life; for those areas or parts not often washed by rain, should be regularly washed with water.

家電正在邁入“彩色時(shí)代”。隨著人們生活水平的提高，同生活信息息息相關(guān)的家電產(chǎn)品也開始追求時(shí)尚外觀，在我國家電業(yè)的發(fā)展歷程上，大件家電通常的色調(diào)被分為“黑電”和“白電”兩大系列。

Home appliances are entering the "color era". With the improvement of people's living standard, the home appliance products that are closely related to life information also begin to pursue fashionable appearance, on the development course of our country home appliance industry, the usual tone of big home appliance is divided into "black electricity" and "white electricity" two big series.
