彩钢板在施工中使用时，总是要对彩钢板进行打磨，主要是为了保持彩钢板的美观，保证施工安全。彩钢板的抛光有三种方法：湿磨、机械磨和干磨
一。湿磨：水砂纸蘸水或肥皂水可对彩钢板进行抛光，可减少磨痕，提高镀层的光洁度，节省砂纸和人力。但是，在喷涂底层涂料时，水磨砂彩钢板的生产厂家应注意以下几点：首先，底层涂料只能在水磨砂层完全干燥后才能喷涂，否则漆层容易变白，另外，吸水性强的基材不宜浇水。
2。机械研磨：为提高济南彩钢板大型施工的工作效率，可采用机械彩钢板生产厂家的研磨方法，如电动研磨机，圆盘式和振动式。
三。干砂：砂纸用于砂光，适用于硬脆油漆。彩色钢板打磨的缺点是在操作过程中会产生大量的粉尘，影响环境卫生。
目前移动住宅价格总趋势正在缓慢下滑。目前，我国经济总体处于衰退状态，许多小制造商纷纷倒闭，大量资金流入其他行业。从发展趋势看，活动房市场处于上升状态。大量资金投入活动房市场，增加了活动房的竞争。为了争夺市场份额，不少厂家采取降价促销的手段，使得整个活动楼市的价格更低。特别是在移动住宅市场，由于进入门槛较低，移动住宅的生产厂家众多，竞争更加激烈，价格波动也比较大。
活动房屋重量轻、结构简单、抗风能力弱，必须由正规厂家安装，才能起到良好的防风作用，
其次，采用聚苯乙烯作为夹芯板时，应注意彩钢板活动房的防火。例如，电焊施工不应靠近墙面进行，冬季应在加热炉上加装防火装置净化彩钢板厂家，室内线路敷设时应采用金属管。金属管应可靠接地或采用耐火管。另外，穿墙时应加套管保护。禁止在需要防水处理的屋顶上使用喷灯！
施工完毕后，检查各部位连接及加固情况，并注意檩条型号不宜过小。
彩钢板的一些特性和性能
彩钢板涂料是由冷轧钢板和镀锌钢板经表面化学处理后，再经烘烤、固化后，通过涂覆（辊涂）或复合有机膜（PVC膜等）制成的产品。也有人称该产品为“预滚彩涂钢板”和“塑料彩涂钢板”。彩钢板产品是生产厂家在连续生产线上生产的，故又称彩钢板卷。彩钢板不仅具有机械强度高、易成型的钢材性能，而且具有良好的装饰性和耐腐蚀性。彩钢板是一种在国际上备受推崇的新材料。随着科学技术的进步，环保意识的增强，人民生活水平的提高，彩钢板移动房屋显示出越来越强大的生命力和广阔的市场前景，受到建筑、家电、机电、交通、室内装饰等行业的青睐，办公用具及其他行业。
When the color steel plate is used in construction, it is always necessary to polish the color steel plate, mainly to maintain the beauty of the color steel plate and ensure the safety of construction. There are three methods for polishing the color steel
plate: wet grinding, mechanical grinding and dry grinding
1. Wet grinding: water abrasive paper dipped in water or soapy water can polish color steel plate, which can reduce grinding marks, improve the smoothness of coating, and save sandpaper and labor. However, when spraying the lower layer of paint, the manufacturer
of water abrasive color steel plate should pay attention to the following: first, the lower layer of paint can only be applied after the water abrasive layer is completely dry, otherwise the paint layer is easy to whiten, in addition, the base material
with strong water absorption should not be watered.
2. Mechanical grinding: in order to improve the working efficiency during the large-scale construction of Jinan color steel plate, the method of grinding by mechanical color steel plate manufacturer
can be adopted, such as electric grinder, with disc type and vibration type.
3. Dry sanding: sandpaper is used for sanding, which is suitable for hard and brittle paint. The disadvantage of sanding color steel plate is that there will be a lot of
dust in the process of operation, which will affect the environmental health.
At present the general price trend of mobile housing is slowly sliding down. At present, the overall economy is in recession, many small manufacturers have closed down,
and a large number of funds have flowed into other industries. From the perspective of development trend, the market of activity house is in a rising state. A lot of funds have been invested in the market of activity house, increasing the competition
of activity house. In order to compete for market share, many manufacturers have adopted the means of price reduction to promote sales, making the price of the whole activity house market lower. Especially in the mobile housing market, due to the low
entry threshold, there are many manufacturers of mobile housing, and the competition is more fierce, and the price fluctuation is relatively large.
Due to its light weight, simple structure and weak wind resistance, the movable house must be installed
by a regular manufacturer, so as to play a good role in wind protection,
Secondly, if polystyrene is used as sandwich board, attention should be paid to fire prevention in the color steel plate mobile room. For example, electric welding construction
should not be carried out near the wall, fire prevention devices should be added to the heating stove in winter to purify color steel plate manufacturers, and metal pipes should be used when laying indoor lines. Metal pipe shall be reliably grounded or
refractory pipe shall be used. In addition, casing shall be added for protection when passing through the wall. It is forbidden to use blowtorch on the roof requiring waterproof treatment!
After the completion of construction, check the connection
and reinforcement of each part, and pay attention to the purlin model not too small.
Some characteristics and properties of color steel plate
Color steel plate coating is a product made of cold-rolled steel plate and galvanized steel plate
by coating (roller coating) or composite organic film (PVC film, etc.) after surface chemical treatment and then baking and curing. Some people also call this product "pre roll color coated steel plate" and "plastic color steel plate". Color plate products
are produced in continuous production line by the manufacturer, so it is also called color coated steel plate roll. Color steel plate not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decorative
and corrosion resistance of coating materials. Color steel plate is a new material highly praised in the world. With the progress of science and technology, the enhancement of environmental awareness, and the improvement of people's living standards,
color steel plate mobile houses show more and more strong vitality and broad market prospects, and are favored by construction, home appliances, electromechanical, transportation, interior decoration, office appliances and other industries.
