    肯德基門窗要考慮哪些?
    來源: 2020-07-03 20:12:50
    1 、強度
    1. Strength
    鋁合金門窗的強度是由在壓力箱內對鋁合金門窗進行壓縮空氣加壓試驗時所承受風壓的等級來表示。一般性能的鋁合金門窗強度可達1961Pa~2353Pa,高性能鋁合金門窗可達2353Pa~2746Pa。在上述壓力下測定鋁合金門窗扇:中央最大位移最應小于鋁合金門窗框內沿高度的1/70。
    The strength of aluminum alloy doors and windows is expressed by the level of wind pressure borne by compressed air pressure test on aluminum alloy doors and windows in the pressure box. The strength of general performance aluminum alloy doors and windows can reach 1961pa ~ 2353pa, and high performance aluminum alloy doors and windows can reach 2353pa ~ 2746pa. Under the above pressure, the maximum central displacement should be less than 1 / 70 of the inner edge height of the aluminum alloy door and window frame.
    2、氣密性
    2. Air tightness
    鋁合金門窗在壓力試驗箱內,使鋁合金門窗的前后形成4.9Pa~2.94Pa的壓力差,其每1平米面積每1h 的通氣量,表示鋁合金門窗的氣密性,單位是m3/h m2。一般性能的鋁合金門窗,當前后壓力差為1000Pa時,氣密性可達8m3/h m2以下,高密封性能的鋁合金門窗可達2.0 m3/h m2以下。

    In the pressure test box, the pressure difference between the front and rear of the aluminum alloy doors and windows is 4.9pa ~ 2.94pa. The ventilation volume of every 1 square meter area every 1H indicates the air tightness of the aluminum alloy doors and windows, and the unit is m3 / hm2. When the current back pressure difference is 1000Pa, the air tightness of aluminum alloy doors and windows with general performance can be less than 8m3 / hm2, and that of high sealing performance can be less than 2.0m3/hm2.

    3、水密性
    3. Water tightness
    鋁合金門窗在壓力試驗箱內,對鋁合金門窗的外側加入周期為2S的正弦波脈動壓 力,同時向鋁合金門窗以4L/m2 min的淋水量人工降雨,進行連續10min 的風雨交加試驗,在室內一側不應有可見的漏滲水現象。水密性用試驗時施加的脈沖風壓平均壓力表示。一般性能鋁合金門窗為343N/ m2,抗臺風的高性能鋁合金門窗可達490N/ m2。
    For aluminum alloy doors and windows, a sine wave pulsating pressure with a period of 2S is added to the outside of the aluminum alloy doors and windows in the pressure test box. At the same time, the aluminum alloy doors and windows are subjected to 10 min continuous wind rain alternating test with 4 L / m2 min pouring water. There should be no visible water leakage on the indoor side. The water tightness is expressed by the average pressure of impulse wind pressure applied during the test. The general performance of aluminum alloy doors and windows is 343n / m2, and the high performance aluminum alloy doors and windows with typhoon resistance can reach 490N / m2.
    4、開閉力
    4. Opening and closing force
    當裝好玻璃后,鋁合金門窗扇打開或關閉所需的外力應在49N以下。
    When the glass is installed, the external force required to open or close the aluminum alloy door and window leaf should be less than 49n.
    5、隔音性
    5. Sound insulation
    在音響試驗室內對鋁合金門窗的音響透過損失進行試驗可以發現,當音響頻率達到一定值之后,鋁合金門窗的音響透過損失趨于恒定。用這種方法測定出隔音性能的等級曲線。有隔音要求的鋁合金門窗音響透過損失可達#89,即音響透過鋁合金門窗后聲級可降低25dB。高隔音性能的鋁合金門窗,音響透過損失等級曲線30dB ~45dB。
    When the sound frequency reaches a certain value, the sound transmission loss of aluminum alloy doors and windows tends to be constant. The grade curve of sound insulation performance is determined by this method. The sound transmission loss of aluminum alloy doors and windows with sound insulation requirements can reach ා 89, that is, the sound level can be reduced by 25dB after the sound passes through the aluminum alloy doors and windows. The sound transmission loss level curve of aluminum alloy doors and windows with high sound insulation performance is 30dB ~ 45dB.
    6、隔熱性
    6. Thermal insulation
    通常用鋁合金門窗的熱對流阻抗值來表示隔熱性能,單位是m2 h ℃/kJ。一般分成三級:R1=0.05,R2=0.06,R3=0.07。采用6mm雙層玻璃高性能的隔熱鋁合金門窗,熱對流阻抗值可以達到0.05m2 h ℃/kJ。
    Generally, the thermal convection impedance of aluminum alloy doors and windows is used to express the thermal insulation performance, and the unit is M2 h ℃ / kJ. Generally divided into three levels: R1 = 0.05, R2 = 0.06, R3 = 0.07. The thermal convection impedance can reach 0.05m2h ℃ / kJ by using high performance thermal insulation aluminum alloy doors and windows with 6mm double glass.
    7、尼龍導向輪耐久性
    7. Durability of nylon guide wheel
    鋁合金推拉門窗活動門窗扉用電動機經偏心連桿機構作連續往復行走試驗,尼龍輪直徑12mm~16mm試驗一萬次;尼龍輪直徑20mm~24mm試驗5 萬次;尼龍輪直徑30mm~60mm試驗10萬次,鋁合金門窗及導向輪等配件應無異常損壞。
    The motor of aluminum alloy sliding door and window movable door and window is tested continuously by eccentric linkage mechanism. The nylon wheel diameter is 12mm ~ 16mm, 10000 times; the nylon wheel diameter is 20mm ~ 24mm, 50000 times; the nylon wheel diameter is 30mm ~ 60mm, 100000 times. The aluminum alloy door and window and guide wheel shall be free from abnormal damage.
    8、開閉鎖耐久性
    8. Opening and locking durability
    開閉鎖在試驗臺上用電動拖動,以每1min10次~30次的速度進行連續開閉試驗,當達到3萬次時應無異常損傷。
    Open and close test shall be carried out continuously at the speed of 10 ~ 30 times per 1min by electric drive on the test bench. When it reaches 30000 times, there shall be no abnormal damage.
    肯德基門需要定期進行清潔和檢修,否則就會在門的邊縫處集聚大量的塵土,從而導致門的組件運轉不靈活,而且如果不對肯德基門進行定期的清潔的話,也會在很大程度上影響店面的美觀和潔凈。因此在使用肯德基門的過程中一定要注意對門的定期清潔和檢修
    KFC doors need to be cleaned and overhauled regularly, otherwise, a lot of dust will be accumulated at the edge seam of the door, which will lead to the inflexible operation of the door components. Moreover, if the KFC door is not cleaned regularly, the beauty and cleanliness of the store will be greatly affected. Therefore, in the process of using KFC door, we must pay attention to the regular cleaning and maintenance of the door
