Some owners of the winter decoration are very tangled. On the one hand, I heard that there are many drawbacks in the winter decoration. On the other hand, some building materials at this time are more favorable. So what aspects of the winter decoration should be understood? Below, Xiao Bian took everyone to see the advantages and disadvantages of the winter decoration. Authentic lighting Disadvantages: Difficult-to-dry paint causes wall cracks The specification of the paint often states that the ambient temperature for construction should not be less than 5 degrees. It is understood that if the temperature does not meet the requirements, it will be susceptible to freezing during the plastering and scraping operations, which will lead to quality problems such as hollowing out in the future. At the same time, low temperatures in winter and weak sunlight will slow the drying speed of the brushing surface. In spring and autumn, the painted walls usually dry out in half to 1 day. However, in the winter, they need to be aired for 1-2 days. In addition, due to the dry weather in winter, the wall surface is prone to cracks such as hair. Cement freezes affect bonding strength Due to the low temperature in winter, the cement mortar is easy to freeze. However, this state is not a true solidification and its bonding strength is not high. Because the temperature is low, there will be crushed ice pieces in the cement mortar. When the ice blocks melt, the ceramic tile will not adhere tightly. This is the main reason why tiles laid under low temperature conditions are likely to fall off during the summer. Winter decoration period is relatively long The construction period in winter is often longer than that in spring and autumn. On the one hand, in order to ensure that the temperature of the construction environment meets the standard, it is often only constructed between 10:00 am and 4:00 pm, virtually shortening the daily working hours. At the same time, low temperatures can also lead to a slower drying rate, which delays the schedule. On the other hand, the Spring Festival holiday is also one of the reasons for the long winter decoration period. It is understood that workers' holiday during the Spring Festival is generally longer, usually around 15 days. Harmful gas is not easy to release During the renovation process, certain harmful gases will remain more or less. Since there is very little window ventilation in the winter, harmful gases can easily accumulate in the living room and are difficult to release. In addition, the release of harmful gases is related to temperature. The higher the temperature, the greater the volatilization of harmful gases such as formaldehyde and benzene. Therefore, if the construction acceptance in winter, the indicators just reach the standard, once entering the hot season, the harmful substances in the air will be May exceed the standard. advantage: Designers take orders less After winter, the decoration will enter the off-season. Designers will have more time to communicate with the owners and make the design plan closer to the needs of the owners. At the same time, the design plan after repeated consideration will be relatively perfect. It is understood that the designer spends no less than two weeks on the concept design plan. In the relatively cold winter of the business, due to the small number of orders, the designer will have ample time to spend time on the concept plan and at the same time During the construction process, the designers will also be relatively "enthusiastic", and during the peak season, the situation of "not seen by designers after the start of construction" will also be eased. Dodge the construction management of peak period In the high season of decoration, a foreman often needs to take care of 5 or 6 sites at the same time. Some “star†foremen even have to travel to and from more than ten sites. However, avoiding the peak period of start-up work, the construction site of the foreman is small, ensuring that the project management work on each site can be more meticulous and in place. At the same time, it is also conducive to the selection of excellent construction workers. It is understood that in the season of renovation, it is often difficult for workers to find. A skilled worker often has several households waiting in line, and some even wait for work stoppages. Wood moisture content is not easy to deform In winter, the moisture content of wood is the lowest in the year, and the degree of drying is good. Therefore, the woodworking of winter decoration is not easy to crack in spring and summer. If there is a margin in the construction, even in the summer, The deformation caused by the expansion of the wood is also controlled. In addition, during the 30 to 60-day period, the heating in the winter room will quickly expose the problems in the carpentry, forcing the decoration company to make timely corrections. For example, in a dry environment, potential problems such as dry cracking and deformation of wood are often revealed before the project is completed or even before the paint is painted. In this way, the owner can supervise the construction personnel to repair or dismantle them in time. Decoration discounted building materials prices less moisture In winter, due to the reduction in the amount of decoration, some decoration companies will launch special discount policies, and building material traders will often launch discounted merchandise. At the same time, the prices of building materials have been rising in recent years. It is understood that merchants will often choose to increase the prices of their products before the peak season. Therefore, in the winter, building materials will be relatively low in price. In addition, the off-season building materials delivery cycle is relatively short.

Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of Angular Contact Ball Bearing and can bear combined radial and axial load.
Thin wall ball bearings have a bearing inner diameter and outer diameter ratio less than a specified value. The ratio of bearing outer diameter to bearing inner diameter is 1.25 or less. It is called thin wall ball bearings, which means that the outer diameter-inner diameter value of the bearing is very small and the bearing wall is very thin.

When the speed is high and thrust ball bearings are not suitable, thin wall ball bearings can also be used to bear pure axial loads. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient and a high limit speed. But it is not impact resistant and not suitable for heavy loads.
The precision required by thin wall ball bearings is very high, because the wall is very thin, so the weight it can carry is also very low, and the impact resistance is very poor, so this must be selected according to the use environment!
