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.
