Zhongtao Sanitary Ware How to deal with the cracked bathroom cabinet must be seen! As long as the bathroom cabinet undergoes formal and strict drying treatment, the cracks will not be obvious. Even if there is cracking, it is very small and usually does not affect the use. Although there are many reasons for the cracking and deformation of bathroom cabinets, the woodiness of “dry shrinkage and swelling” is the “culprit” that causes the bathroom cabinets to deform and crack: when the air is extremely dry, the bathroom cabinets will Lose water and shrink. On the contrary, when the humidity increases, the bathroom cabinet will absorb moisture and expand slightly. There are three main types of water in wood, namely free water, adsorbed water and bound water. Free water is the water that exists in the cell cavity and interstitial spaces of wood. The change of free water is only related to the apparent density, preservation, combustibility, and dryness of the wood; the adsorbed water is adsorbed between the fine fibers in the cell wall The changes in moisture and adsorbed water are the main factors that affect the strength and swelling and shrinkage of wood. Bound water is the combined water in the wood, which does not change at room temperature, so it has no effect on the properties of wood. When there is no free water in the wood and the adsorbed water in the cell wall is saturated, the moisture content of the wood at this time is called the fiber saturation point, which is the turning point of the change in wood properties. The value varies depending on the tree species, temperature and measurement method. Usually 30% is used as the average value of the moisture content of each tree species. What is the moisture content of wood? Under normal conditions, wood and its products will have a certain amount of moisture. my country defines the percentage of the weight of the moisture in the wood to the weight of the wood after the absolute dryness as the moisture content of the wood. The moisture content can be calculated based on the weight of the dry wood, and the calculated value is called the absolute moisture content, and is referred to as the moisture content (W, %) for short. Calculation formula: Wu003d(Gs-Ggo)/Ggo×100% where: W—absolute moisture content of wood; Gs—weight of wet wood; Ggoo—weight of absolutely dry wood. The importance of wood moisture content Why does the bathroom cabinet have quality problems such as cracking and deformation? How to reduce the loss of these problems to the enterprise? After the bathroom cabinet is finished, the shape and material will not change. At this time, the key factors that determine the internal quality of the bathroom cabinet are mainly the moisture content of the wood and the drying stress. Bathroom cabinet manufacturers need to correctly grasp the moisture content of wood products. When the bathroom cabinet reaches the equilibrium moisture content when it is used, the wood at this time is the least likely to crack and deform. The swelling and shrinking of wood are caused by the changes in the absorption of water in the wood cell wall. When the moisture content of the wood is lower than the fiber saturation point, it will continue to be dried and the volume will shrink; when the dried wood absorbs moisture, as the absorbed water increases, it stops when the moisture content of the fiber saturation point is reached. When the moisture content of the wood is above the fiber saturation point and only the free water changes, the volume of the wood does not change. Because wood is a non-homogeneous material, its expansion and contraction deformation are different in all directions, of which the chord direction is the largest, the radial direction is the second, and the longitudinal direction (that is, along the fiber direction) is the smallest. When the wood is dry, the chord shrinkage is about 6%-12%, the radial shrinkage is 3%-6%, and the longitudinal shrinkage is only 0.1%-0.35%. It is precisely because of the unevenness of the wood structure that the expansion and contraction of the volume of the wood may cause the deformation and warpage of the wood. The wood is dry, the drier the better? Wood is placed in a certain environment, after a long enough time, its moisture content will tend to an equilibrium value, which is called the equilibrium moisture content of the environment. When the moisture content of the wood is higher than the equilibrium moisture content of the environment, the wood will absorb moisture and shrink, otherwise it will absorb moisture and expand. For example, the average annual equilibrium moisture content in Guangzhou is 15.1%, while that in Beijing is 11.4%. Wood dried to 11% is suitable for use in Beijing. It can be used in Guangzhou and will absorb moisture and swell and cause deformation. Therefore, wood drying should be appropriate, not as dry as possible. Different regions and different uses have different requirements for the moisture content of wood. The main reason for the cracking and deformation of bathroom cabinets is the imbalance between the moisture content of the wood and the moisture content of the external environment. The equilibrium moisture content of wood varies with the region where it is located. It is about 12% in the north of my country, about 18% in the south, and 15% in the Yangtze River Basin. Tips for preventing cracking of bathroom cabinets Under normal circumstances, bathroom cabinets have to go through a drying process during the production process, so that the wood properties of swelling and shrinking are released before production. This can to a large extent prevent the bathroom cabinet from cracking and deforming during use, but it is not absolute, and some maintenance should be paid attention to when using it. Applying wood wax oil regularly to moisturize wood cannot only be maintained by maintaining a suitable indoor air humidity. For example, wood wax oil is like a skin moisturizing skin care product. When applied to the solid wood bathroom cabinet, it will lock the moisture in the wood and prevent the bathroom cabinet from cracking and deforming. It is not only useful for preventing drying, but also for preventing the solid wood bathroom cabinet from getting too wet. It is generally recommended to use wood wax oil for full application care every 3-4 months. Waterproof Aluminum Foil Natural Enemy of Condensate According to our usual bathing experience, we will find that the basin or faucet in the bathroom will produce a lot of condensed water when encountering hot air. This water will flow into the bottom of the cabinet along the countertop, causing the cabinet to become moldy and deformed. If you can add a layer of waterproof aluminum foil or rubber pads to the bottom of the cabinet in time, you can solve this problem. Put them on the bottom of the drawer to keep the bath products in place while preventing moisture. Properly increase the humidity. If the climate is particularly dry, you can sprinkle some water on the bathroom cabinet to prevent it from cracking. Northern families can install humidifiers to increase the humidity in the room, which is not only good for people's living, but also very helpful for the maintenance of bathroom cabinets. Of course, don't let the bathroom cabinet always be in a damp environment, so as to avoid mildew of the bathroom cabinet. For example, keeping the bathroom cabinet close to a damp wall for a long time will cause the wood to absorb moisture and expand, which is easy to crack and mold, so it is necessary to frequently dehumidify.
