當在煤礦(kuang)下操作由塑(su)料和橡(xiang)膠材(cai)料制成的(de)輸送帶時，由于帶上(shang)(shang)的(de)正負(fu)電(dian)荷由于摩擦而失衡，因(yin)此(ci)會(hui)產生靜電(dian)荷。靜電(dian)荷積聚在傳送帶的(de)表(biao)面上(shang)(shang)，很容(rong)易消失。當達到某個值時。接地的(de)物(wu)體上(shang)(shang)會(hui)產生火花，引(yin)起(qi)火災或爆炸(zha)。

對(dui)于(yu)煤礦中的(de)PVC阻燃輸(shu)送帶(dai)(dai)，配方的(de)抗(kang)靜(jing)電性能是一個非常重要的(de)問題。為了(le)使(shi)輸(shu)送帶(dai)(dai)運行過(guo)程中產(chan)生的(de)靜(jing)電荷(he)通過(guo)并泄漏出去，我(wo)們必須考慮工藝狀態，生產(chan)成本等。考慮多種因素，選(xuan)擇合適的(de)抗(kang)靜(jing)電劑和導電材(cai)料以減少靜(jing)電的(de)產(chan)生。 PVC阻燃輸(shu)送帶(dai)(dai)的(de)表面電阻可確保輸(shu)送帶(dai)(dai)的(de)表面電阻不超過(guo)3×108Ψ。

抗靜電方法

        目前，輸(shu)送帶的(de)(de)抗靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)方法主(zhu)要靠(kao)控制靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)產生(sheng)和積(ji)累。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)控制主(zhu)要是通(tong)(tong)過(guo)減少(shao)或(huo)防止摩(mo)擦(ca)來減少(shao)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)產生(sheng)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)積(ji)累主(zhu)要是通(tong)(tong)過(guo)地面(mian)傳導(dao)(dao)，增加環境的(de)(de)相(xiang)對濕度(du)，并添(tian)(tian)加抗靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)劑或(huo)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)材料(liao)(liao)（如(ru)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)炭黑，金屬(shu)粉等(deng)）來加速靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)泄(xie)漏并避免大量(liang)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)產生(sheng)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)積(ji)聚。因此，為(wei)了賦予具(ju)有(you)(you)(you)良好(hao)絕(jue)緣性(xing)(xing)能的(de)(de)塑料(liao)(liao)一(yi)(yi)定的(de)(de)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)(xing)，以下方法:1主(zhu)要用于通(tong)(tong)過(guo)接(jie)枝共聚來改(gai)(gai)變(bian)聚合物結(jie)構(gou)，從而具(ju)有(you)(you)(you)更多的(de)(de)極性(xing)(xing)基(ji)團或(huo)離(li)子基(ji)團，并改(gai)(gai)善導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)(xing)。性(xing)(xing)別。 2.在(zai)塑料(liao)(liao)中(zhong)(zhong)添(tian)(tian)加導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)填(tian)料(liao)(liao)（例如(ru)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)炭黑，金屬(shu)粉等(deng)）。 3.用強氧化劑氧化塑料(liao)(liao)產品(pin)的(de)(de)表(biao)面(mian)，以增加導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)(xing)。 4.在(zai)塑料(liao)(liao)中(zhong)(zhong)添(tian)(tian)加抗靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)劑，或(huo)在(zai)產品(pin)表(biao)面(mian)上使用抗靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)劑。 [1]。在(zai)PVC阻燃輸(shu)送帶的(de)(de)實際生(sheng)產過(guo)程中(zhong)(zhong)，在(zai)涂料(liao)(liao)配方中(zhong)(zhong)加入抗靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)劑和導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)填(tian)料(liao)(liao)，以降(jiang)低輸(shu)送帶的(de)(de)表(biao)面(mian)電(dian)(dian)(dian)(dian)(dian)(dian)阻和體積(ji)電(dian)(dian)(dian)(dian)(dian)(dian)阻，使其具(ju)有(you)(you)(you)一(yi)(yi)定的(de)(de)抗靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)(xing)能。
