防靜電环氧地坪測量必經的幾個施工步驟

防靜電环氧地坪主要運用於電子廠，那麼如何進行靜電測量呢，其實測量主要包括兩個方面，一個是絕緣電阻的測量，另外一個就是靜電釋放時間的測量。防靜電环氧地坪測量包括4個具體步驟，濟南華彩环氧地坪為大傢來做簡單的介紹：
Antistatic epoxy floors are mainly used in electronic factories, so how to carry out static measurement, in fact, the measurement mainly includes two aspects, one is insulation resistance measurement, the other is the measurement of static release time. Antistatic Epoxy Floor Measurement includes four specific steps, Jinan Huacai Floor for you to do a simple introduction:
一、絕緣電阻的測量標準數據：
1. Measurement data of insulation resistance:
在電極的任何點與樣品的邊緣之間的最小距離必須小於50mm。固體絕緣材料一般測定表面電阻和體積電阻。按照GB 1410-1989 的標準要求測量工作至少應在被測物體表面上隨機選取三個測量位置上進行，在電極的任何點與樣品的邊緣之間的最小距離必須小於50mm。
The minimum distance between any point of the electrode and the edge of the sample must be less than 50mm. Solid insulation materials generally measure surface resistance and volume resistance. According to GB 1410-1989 standard, the measurement should be carried out at least on the surface of the印花地坪 object to be measured randomly at three measuring positions, the minimum distance between any point of the electrode and the edge of the sample must be less than 50 mm.
二、靜電釋放時間的測量原理：
Two. The measuring principle of electrostatic release time:
一個帶電物體，其電位自行衰減消散是滿足的指數規律的。放電時間常數て的物理意義是電位值衰減到原點位的e分之一所需的時間，即t=て時，U=0.37Uo。為瞭使用和測量上的方便，一般用帶電體電位衰減到一半所需的時間，即半衰期來表征。由於て半=て×ln2，所以隻要測量出半衰期て半，便可算出放電時間常數て。
A charged object, whose potential self attenuation is dissipated is an exponential law. The physical meaning of the discharge time constant is the time required for the potential value to decay to one-tenth of e at the origin, i.e. when t = _, U = 0.37 Uo. In order to use and measure conveniently, the time required for the potential of charged body to decay to half, that is, half-life, is generally used to characterize. 彩色沥清地坪Since the half-life is half a = LN2, the discharge time constant can be worked out by measuring half half-life.

三、防靜電环氧地坪測量步驟：
Three. Anti-static epoxy floor measurement steps:
1、用靜電電位儀表帶自動打印機每隔一定時間間隔記錄電壓衰減的數值，量取靜電電位Uo下降到0.37Uo所需的時間，即為放電時間常數て;或量取靜電電位Uo下降到0.5Uo所需的時間，也就是半衰期て半。
1. Record the value of voltage attenuation with electrostatic potential instrument and automatic printer every certain time interval. Measure the time required for the electrostatic potential Uo to fall to 0.37 Uo, that is, discharge time constant; or measure the time required for the electrostatic potential Uo to fall to 0.5 Uo, that is, half-life.
2、用有信號輸出口的靜電電位儀記錄靜電位衰減曲線，在曲線上可以根據曲線上的時標，分別量取靜電電位衰減到0.5U及0.37U時所經過的時間，則分別為半衰期て半和放電時間常數て。
2. Record the electrostatic potential attenuation curve with an electrostatic potentiometer with a signal output port. According to the time scales on the curve, the time elapsed when the electrostatic potential attenuates to 0.5U and 0.37U can be measured respectively, and the half-life and discharge time constant are respectively.
3、已知或分別測出材料體電阻率ρ和介電常數ε，可計算出放電時間常數和半衰期。也可以由已知或分別測出材料體電阻Rv和體電容C，或地板對地電阻Re和對地電容Ce，計算出て=RvC或て=ReCe。
3. The discharge time constant and half-life can be calculated by measuring the resistivity and dielectric constant of the material. The volume resistance Rv and the volume capacitance C of the material, or the floor resistance Re and the ground capacitance Ce, can also be measured and calculated as =RvC or =ReCe.
4、利用平板電容離子平衡分析儀，將試樣放在電容平板上充分接觸後，對平板進行充電到一定電壓，然後再斷開充電電源的瞬間，試樣加上一個接地平板電極，然後記錄靜電衰減一半或衰減到0.37U時的時間。
4. Using the flat-plate capacitor ion balance analyzer, after the sample is fully contacted on the flat-plate capacitor, the flat-plate is charged to a certain voltage, and then the charging power is disconnected. The sample is added with a ground-plate electrode, and the time when the static electricity decays to half or 0.37U is recorded.
