At present, geothermal heating technology has been widely used in home decoration. Due to its advantages such as comfort and convenience, it has developed rapidly. However, what kind of floor is suitable for geothermal heating and what are the key issues for installing geothermal floor? Different flooring suppliers from different brands have different opinions and cause consumers to be confused. According to reports, there are three key technologies for installing geothermal floors. First, ground technology processing. Mainly to remove the moisture from the cement floor. If the moisture in the cement floor is not removed before the floor is installed, once heated, a certain amount of moisture shock waves will be generated, which is the main reason for the cracking of the floor. Second, floor installation technology. In order to ensure the installation quality of the geothermal floor, there is a strict set of installation standards for installation of geothermal floors. The installation environment, installation time and installation process are strictly required to ensure the overall quality of the geothermal floor. Third, strict accessories requirements. There is one key detail of the geothermal floor, which is the floor mat of the geothermal floor. The deformation of the floor mat can drive the deformation of the floor. With pvc foam mats, one is slow in thermal conductivity, and the second is prolonged heating and aging. If geothermal floor special floor mats are used, one is that the heat conduction is fast, the second is environmental protection, and the third is no deformation. In addition, when the consumer uses the geothermal heating system in the second year, it must be heated in stages and gradually increase the temperature. Do not adjust the temperature to the highest one at a time. This can easily cause floor damage. The installation of geothermal floor is best to use laminate flooring, because the relative thermal conductivity of the laminate flooring is better, and the solid wood flooring is not easily deformed after being heated; in addition, the product is relatively thin, the general thickness is 8mm, heat conduction is fast, and energy is saved. Geothermal heating has no special technical requirements for strengthening the floor. As long as it is a qualified floor, it can be used as a geothermal floor. Geothermal floor installation with stress: 1. The moisture barrier is required: Geothermal floor pavement requires a layer of moisture-proof membrane to be laid between the floor mat and the ground. This moisture-proof membrane can prevent the evaporation of geothermal heat and damage the floor after evaporating the surface moisture. There may be a lot of manufacturers in order to save a little cost at the expense of reducing the installation requirements, causing great installation risks to the geothermal floor. 2. Careful selection of floor mats: At present, some manufacturers use paper floor mats or aluminum foil floor mats as geothermal heating floor mats. Both of these mats have obvious defects in geothermal heat and directly result in damage to the floor quality. Under the erosive effect of hot evaporation of moisture for a long time, the paper floor mat will gradually rot and lose the moisture resistance of the floor mat so as to damage the floor. The use of aluminum foil floor mats will seriously affect the thermal efficiency. Geothermal heating does not involve convection, so the heat of the geothermal system is achieved through conduction and radiation. However, the aluminum foil on the aluminum foil mat will reflect heat back to the ground, causing the heat radiation to fail to reach the indoor, affecting the heating effect. It also wastes energy. 3, the installation process is particular about: floor installation is not standardized, may cause a variety of quality reasons, such as: uneven floor pavement will cause floor deformation. Therefore, it is recommended that consumers choose good brands. Flooring Considerations Nature Flooring Cement Interior Decor Home Improvement Venous cannula is also a deep venous puncture catheter. The method is to select the appropriate puncture site and insert the needle under the skin, and insert the needle with negative pressure until the dark red blood is absorbed, indicating that the needle has entered the vein, and the guide wire is inserted. Withdraw the puncture needle to leave the guide wire in the blood vessel, and then insert the venous catheter that needs to be indwelled along the guide wire, then exit the guide wire, inject diluted heparin saline and fix the catheter, the deep venous catheterization is completed. The veins for puncture and catheterization are usually selected clinically, including the subclavian vein, internal jugular vein, and femoral vein. After the puncture catheter is indwelled, attention must be paid to the care of the puncture site to avoid infection with thrombus or catheter falling off. venous cannulation,best veins for cannulation,venous cannulation set,venous cannulation technique Yong Yue Medical Technology(Kunshan) Co.,Ltd , https://www.yongyuelab.com
