耐磨防靜電地坪漆有什么樣的指標

一般(ban)來講，涂(tu)膜表面(mian)電(dian)(dian)(dian)阻值在1.0×1010以下即(ji)可(ke)消除積累在涂(tu)膜表面(mian)的靜電(dian)(dian)(dian)荷，根據美國(guo)材料與試驗(yan)協會標準(ASTMF150—98)的規定將電(dian)(dian)(dian)阻值在2.5×104Ω—1.0×06Ω的地板稱為(wei)導電(dian)(dian)(dian)地板；而(er)將電(dian)(dian)(dian)阻值為(wei)l×106Ω—1．0×09Ω的地板稱為(wei)靜電(dian)(dian)(dian)耗散(san)型地板，都(dou)可(ke)以防止靜電(dian)(dian)(dian)荷的積累。

在防靜電(dian)地坪 涂(tu)層(ceng)體系中(zhong)，一般(ban)設計為滲(shen)透導電(dian)底漆(qi)層(ceng)、接地銅箔網絡、導電(dian)中(zhong)涂(tu)找平層(ceng)、導電(dian)批土(tu)層(ceng)和防靜電(dian)面層(ceng)的五層(ceng)結(jie)構。滲(shen)透導電(dian)底漆(qi)層(ceng)的涂(tu)料應(ying)選用滲(shen)透性(xing)強的導電(dian)底漆(qi)，不能片面追求封閉性(xing)，以(yi)避免涂(tu)層(ceng)起殼；接地銅箔網絡要使用平底塑膠刮板壓實自(zi)粘銅箔，以(yi)防止空(kong)鼓的產生；

導(dao)電(dian)(dian)(dian)(dian)(dian)中(zhong)涂(tu)(tu)找平(ping)層(ceng)，在施工時(shi)，一定(ding)要(yao)注(zhu)意(yi)最終表面(mian)的(de)光(guang)滑(hua)性(xing)和平(ping)整(zheng)度；導(dao)電(dian)(dian)(dian)(dian)(dian)批土(tu)層(ceng)，在施工時(shi)，一定(ding)要(yao)注(zhu)意(yi)不能(neng)漏涂(tu)(tu)，從而(er)影(ying)響面(mian)層(ceng)的(de)系統電(dian)(dian)(dian)(dian)(dian)阻；因此在施工時(shi)，以(yi)刮(gua)批二道為宜(yi)。目前(qian)的(de)防靜電(dian)(dian)(dian)(dian)(dian)地坪(ping)涂(tu)(tu)料大都是靜電(dian)(dian)(dian)(dian)(dian)耗散型，容易疏導(dao)靜電(dian)(dian)(dian)(dian)(dian)荷。而(er)對(dui)防靜電(dian)(dian)(dian)(dian)(dian)環氧(yang)地坪(ping)而(er)言，靜電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)場的(de)能(neng)量達到一定(ding)程度后，擊穿(chuan)其(qi)問介質而(er)進行放電(dian)(dian)(dian)(dian)(dian)會對(dui)某(mou)些精密的(de)電(dian)(dian)(dian)(dian)(dian)子元器件造成損害，所以(yi)在防靜電(dian)(dian)(dian)(dian)(dian)環氧(yang)地坪(ping)做好后，首先要(yao)考慮(lv)到的(de)是涂(tu)(tu)層(ceng)的(de)防靜電(dian)(dian)(dian)(dian)(dian)指(zhi)標。而(er)主要(yao)的(de)幾項指(zhi)標包括：

A、耐磨防靜電地坪漆表面電(dian)(dian)(dian)阻(阻值(zhi)符合在1．0×106Ω—1．0×109Ω)一在一給定的(de)通(tong)電(dian)(dian)(dian)時(shi)間(jian)之后(hou)，施加于材料表面上(shang)的(de)標準電(dian)(dian)(dian)極之間(jian)的(de)直流電(dian)(dian)(dian)壓對于電(dian)(dian)(dian)極之間(jian)的(de)電(dian)(dian)(dian)流的(de)比值(zhi)，在電(dian)(dian)(dian)極上(shang)可能的(de)極化現象忽(hu)略不計。

B、系統電(dian)阻(阻值符合(he)在5．0×104Ω—1．0×109Ω)一被(bei)測(ce)物體測(ce)試表面(mian)與被(bei)測(ce)物體接地點之間電(dian)阻總和。

C、系統(tong)接(jie)地(di)(di)電(dian)(dian)阻(zu)(zu)(阻(zu)(zu)值≤10Ω)一。電(dian)(dian)流(liu)由接(jie)地(di)(di)系統(tong)流(liu)入大(da)地(di)(di)再經(jing)大(da)地(di)(di)流(liu)向另一接(jie)地(di)(di)體或向遠(yuan)處擴散所(suo)遇到的電(dian)(dian)阻(zu)(zu)，它
