Qinhuangdao decoration: winter decoration precautions

　　Different from summer decoration, winter decoration has a lot to pay attention to, such as the requirements for ventilation and wood moisture...If you also expect to start decorating the house in winter, then follow Hebei Daheng Decoration Xiaobian to see what matters need to pay attention to winter decoration。If the decoration is not paid enough attention to, the process control is not good, in the winter, it is easy to have some problems, such as the water content of the materials that have just been purchased is relatively high, but the decoration has not been revealed at the beginning。After a period of time, cracks will appear, and the reasons for cracks in wood products are similar。Therefore, winter decoration should choose materials with low water content。

　　First, strictly control the room temperature

　　In the northern winter, when the cold air comes, the temperature will drop sharply。The sudden drop in temperature is a fatal blow to the renovation。Low temperature (especially accompanied by strong winds) will have several effects on building materials, one is shrinkage, and the other is moisture volatilization。Taking wall paint and wood as an example, the sharp drop in temperature will cause the interface between paint and wood to shrink sharply, resulting in various cracking phenomena。

　　Therefore, in the winter construction, we must control the room temperature。When the cold air comes, it is necessary to close the window in time, and when the indoor temperature drops to close to the outdoor temperature, the window is properly opened for ventilation。

　　Winter construction, but also control the joint problem。Take solid wood flooring as an example, in winter decoration, because the board is in a contracting state, if the installation is too dense, the board will expand when the temperature rises in summer, if the joint is too small, because the board does not extend, the floor will be deformed。

　　Special note: It is forbidden to stack materials in the vents in winter construction, such as sliding doors, Windows, doors, etc。When the window is closed, do not carry out volatile engineering items such as paint to avoid poisoning。

　　In winter construction, there are also problems with the use of antifreeze。The use of antifreeze in building decoration can make concrete harden at negative temperatures and achieve sufficient antifreeze strength within a specified time。However, the main components of antifreeze are triethanolamine and nitrite。Nitrites do not accumulate in the human body, but too much at one time can be toxic。

　　There are many kinds of antifreeze ingredients, the key is to choose qualified environmental protection products。According to the Code for Construction and Acceptance of Building Decoration Engineering, when the temperature is lower than 5℃, the mortar used for outdoor plastering can be mixed with concrete antifreeze, and the content should be determined by test。Wall plastering mortar shall not be mixed with antifreeze containing chlorine salt

　　Special note: winter decoration, should try to use other methods to solve the problem of anti-freezing。For example, in masonry construction, "early strength Portland cement" with strong frost resistance can be used to increase the proportion of cement in the configuration。

　　Second, consider the color problem comprehensively

　　Winter decoration can cause an illusion to people's visual senses。For example, when decorating in winter, people will unconsciously like some warmer colors, and they will be uncomfortable in summer。

　　Therefore, in the decoration, we should use some suitable colors。Even if you like warm or cool colors, you need moderate colors to adjust, such as white is the middle color。

　　Acceptance details:

　　After winter decoration, the focus of acceptance should be placed on joints, stickers and patches, and carefully checked for cracks。For wall tiles, gently tap the corners and middle of the tiles with a small metal hammer。Under normal circumstances, there should be no hollow sound。If the seal of the wall tile is smooth and strict, the whole plane should be smooth。Also carefully check the floor for obvious gaps and unevenness, and whether the seam between the floor and the baseboard is tight。However, some gaps are allowed because wood floors should be sutured properly in the winter。

　　Three, moderate window ventilation

　　Window ventilation is conducive to the evaporation and drying of indoor harmful substances such as formaldehyde and paint products。However, due to the low outdoor temperature in winter, the paint will deteriorate and even become powdery。And the wall paint that is not thoroughly dried after renovation is easy to freeze, and it is easy to cause wall discoloration after spring。Therefore, ventilation in the warm afternoon, ventilation time should not be too long。

　　How to prevent open water pipes from freezing

　　There should be no problem in the winter when the waterway is concealed, and whether the exposed water pipes and taps need anti-freezing treatment？How to do？(In the yard on the first floor, used for yard cleaning)

　　Frozen faucets in the yard are a new problem。It is recommended to install the valve indoors and close the valve indoors in freezing weather。

　　PPR insulation pipe is used to lay directly, and the effect is good。

　　PPR pipe external insulation steps:

　　1. Cut the pipe insulation layer

　　2.Cut off insulation for tees and elbows

　　3.Glue the seams of the insulation

　　4.Brush glue on the sides of the insulation

　　5, insulation layer bonding, compaction

　　6.Insulation of valves and bends
