As people’s living standards have been increasing, people’s demands for quality of life have also been increasing, and the warmth has been used by more and more people because of their features of comfort, energy saving, environmental protection, and health. It has also been developed from the original high-end to the civilian population. In addition, many ordinary houses have also begun to use floor heating. Compared to villas or duplex buildings, the average size of houses is relatively small, and most of them are centralized heating radiator heating systems. Since the floor heating is low-temperature floor radiation heating, there are relevant requirements for the floor height and water temperature. Therefore, attention must be paid when carrying out renovations. The following points are relevant: First, the height Because floor heating is buried in the underground heating system, the height of the ground will be increased. Generally, it will increase by 6 to 8 centimeters. Therefore, it is necessary to fully consider whether the height of the room after completion of warming has no impact on life. If there are two methods that can affect the height of the room, each one can solve this problem. First, plan the ground and lower the height of the ground by four centimeters. The second is to do a thin floor heating, now the height of the thin floor heating can be achieved 2 cm, plus the ground decoration layer is about 4 cm. Second, the water temperature The floor heating is a low-temperature floor heating. The water temperature is required to be about 60°C. The central heating water temperature is 75-85°C. This requires the mixing water cooling system. Some floor heating companies do not install water cooling devices at the time of floor heating design. First, they will increase the investment cost if they are in trouble. In terms of a 60-square-meter unit, if the water mixing device is added, the cost will account for the total cost of floor heating. Two-fifths, so some non-professional heating companies will not design mixing water cooling devices. The problem has to be solved by increasing the coil spacing or controlling the water flow of each floor heating pipe. This can only control the room temperature, but can not control the warm water supply temperature, and the water temperature is too high will affect the life of warm pipe, the higher the temperature the warmer pipe life is shorter, if the long-term work of high temperature, floor heating pipe is only a short dozen Years of life, so you must pay attention to the control of water temperature. Third, use In the first use of the floor heating should pay attention to slowly warming, the beginning of the water temperature is 18 °C, the next day 25 °C, the third day of 30 °C, until the water temperature to warm the design requirements, if the warming too quickly will result in floor heating and thermal layer and the ground The decorative material is cracked and twisted due to sudden thermal expansion. When the system is turned off, it should be cooled slowly as it is turned on. Clean the filter before and after the end of heating to prevent the filter from blocking the heating effect. Although the floor heating is now the trend of decoration, but in the selection also have to choose according to their own actual situation, only for their own heating system is the best way of heating.

A pipette, also known as a pipette gun, is a device used to quantitatively transfer liquids. When conducting research in analytical testing, a small or trace amount of liquid is generally removed with a pipette. Pipettes can be divided into gas piston pipettes (Air-displacement pipette) and external piston pipettes (Positive-displacement pipette) according to the principle. Gas piston pipettes are mainly used for standard pipetting, and external piston pipettes are mainly used to handle special liquids such as volatile, corrosive and viscous. Many people ignore the correct use of pipettes and some of the details.
