■ Woodworking products are dry and fragile.
Many people don't know that wood-based panels used for decoration in winter, especially veneer plywood, are in the driest time, so their surfaces are very brittle after production. The occurrence of this problem may not be obvious at first, but if the painter can't keep up with the paint sealing work, it will easily lead to the cracking of the veneer on the veneer plywood surface, which will be unsightly and affect the service life. In fact, this problem is well solved: the purchased materials are not stored in the open air; After the materials are transported into the construction site, don't put them near the tuyere or heating, so as not to dry too fast; After carpentry is finished, workers should keep up with the sealing work as soon as possible to isolate the evaporation of water, which plays a very good role in the later protection of woodworking products.
■ Precautions for removing and replacing the heating device
People pay more and more attention to indoor heating facilities, especially the choice of radiator (heating). The cast iron radiator is not satisfactory in both style and heating effect. Therefore, many people replace the radiator when decorating.
At present, the pressure of hot water in our radiator is very high. If hot water breaks through the radiator or water pipe fittings, the water pressure can completely knock over the adults standing in front. Moreover, the construction enterprise or factory that replaces the radiator has no relevant equipment to test the pressure resistance of the radiator, and the replacement of the radiator depends entirely on the experience of its own construction personnel, which is not completely reliable. Therefore, the author warns consumers who are ready to replace radiators that it is best not to replace them at will. If it must be replaced, it is best to find workers from experienced property management companies. In addition, problems can be solved at any time.
■ Be careful when replacing external windows.
There are also some problems that need to be paid attention to when replacing ordinary steel windows or aluminum alloy windows with plastic steel windows. First, the replacement of external windows must be fixed. There is a big sandstorm in the north in winter. In order to save trouble, some workers who install plastic steel windows have not fixed the foundation of plastic steel windows very firmly. Doing so will deform the original square window by the wind (relatively speaking, of course), or tilt the vertical window. Maybe it will become more and more problematic to push and open the window in the future, and rain will flow into the room during the rainy season. Second, the cement mortar around the sealed outer window must be sealed tightly. There is an old saying that "a hole with a big needle and a big nose hits a strong wind", which means to plug up the air leakage place, otherwise in the coldest winter, we will find waves of cold air blowing from nowhere in a well-heated room. Third, the sealing strip of plastic steel window should not be sealed too tightly. Many substances have the problem of thermal expansion and cold contraction, and the rubber sealing strip for plastic steel windows is no exception. Installation in autumn and winter will shrink to a certain extent, and heating in hot summer will expand.
