The doors and windows of the building are the components of the building's peripheral structure. It is the most sensitive part of the building's heat exchange. The energy consumption per unit area is 5-6 times that of the wall, and the heat loss of doors and windows accounts for more than 40% of the entire building. There are three ways to reduce the heat loss of the doors and windows outside the building: first, the heat conduction loss through the aluminum alloy profile; second, the radiant heat loss through the glass; and third, the air convection heat loss through the door and window gap. Therefore, the production of thermal insulation and energy-saving aluminum alloy doors and windows should also be considered from these three aspects. 1. Aluminum alloy profiles Aluminum alloy materials are good conductors of heat, and the thermal conductivity is mostly high. To make the heat-insulating glass, it is necessary to select the profile with the heat-insulated bridge, that is, the passage for the heat conduction of the partition to achieve the purpose of thermal insulation. 2, glass Insulating windows and doors need to use insulating glass, because the cavity between the insulating glass is filled with dry and static air, which greatly reduces the thermal conductivity. Therefore, the insulating glass has excellent heat insulation, sound insulation and frost resistance condensation. Performance, commonly used hollow glass glass thickness 5~6mm, common cavity thickness is 9mm, 12mm. 3, sealing material The sealant used for thermal insulation doors and windows should be weather-resistant adhesive. The sealant strip should be made of neoprene products with excellent ozone corrosion resistance and UV aging resistance. Three or more sealing strips should be set for the door and window sash opening overlap. The main factors that need to be considered when using a basic Peristaltic Pump include the compatibility of the liquid with the Peristaltic Pump Tubing used, the trade-off between flow rate and pulse rate(roller number), Each rotation will dose equal liquid volume which ensures the flow accuracy. and the roller number decides the pulsation of the liquid, if you need a low pulsation liquid delivery, pls choose the multiple rollers to pump head or work with the Pulsation damper.
