Description
技术领域:
本发明涉及一种带电设备用清洗剂,特别是涉及一种通信设备带电清洗用高绝缘清洗剂及其制备方法。
背景技术:
设备在运转过程中均受到周围环境、气候的影响,对于室内的设备,大多是受到机房空气的影响,而对于室外设备,除了受到周边空气环境的影响外,室外设备还受到各种气候的变化如雾、雨、雪、冰等等的影响。粉尘及静电对设备的侵害最为突出:粉尘的危害:(1)粉尘累积使元器件表面的温度升高。数据表明,当温度升高10℃,设备的可靠性将下降25%;当温度继续上升,可能会将温度性较差的元件或接线烧坏。(2)粉尘受到潮气后形成微电路,造成电路漏电、电化学腐蚀,导致性能改变、退化和失效等严重事故。
静电的危害:静电放电引起的元器件击穿损害是电子工业最普遍、最严重的危害。当静电积累到一定程度时发生剧烈放电,即静电放电(ESD),最高电压可达几千乃至几万伏,势必对静电敏感组件造成损害;静电放电(ESD)及电气过载(EOS)对电子元器件造成损害的主要机理有热二次击穿、金属镀层熔融、介质击穿、气弧放电、表面击穿等,静电所造成的危害已危及各个技术领域。
通信网络设备带电清洗维护的目的:1.通过清洗去除设备表面及深层灰尘、油污、潮气、炭渍等有害物质,消除电路板漏电、电化学腐蚀,消除导致电路性能改变、退化和失效的根源。2。有效消除静电,防止电路击穿,保证设备正常工作以及避免重大恶性事故的发生。3.防止设备老化,延长使用寿命,提高设备利用率。4.将各种故障隐患消除在萌芽状态,保证设备的最佳使用状态,将计划外停机概率降到最低。5.保障设备稳定运行,使用户的信号畅通无阻,增加运营收入,提高企业经济效益。
发明内容:
本发明所要解决的技术问题是:克服现有技术的不足,提供一种具有高绝缘、不燃烧、易挥发、对人体无害、对设备无腐蚀等特点且具有超强的渗透力和溶解力的通信设备带电清洗用高绝缘清洗剂及其制备方法。
本发明的技术方案是:
一种通信设备带电清洗用高绝缘清洗剂,以重量份为准由下述组分构成:基础油65~80份、二氯甲烷10~15份、含氟有机溶剂5~15份、含氟表面活性剂0.1~0.5份、硅油0.5~5份。
所述含氟有机溶剂为单一的含氟有机溶剂或至少两种含氟有机溶剂的混合物;所述基础油为馏程在140~200 ℃的烷烃。
所述含氟有机溶剂为全氟庚烷或含氟醚类溶剂;使用单一的含氟有机溶剂在体系中溶解度小,改善耐压值效果有限,引入另一种单纯溶剂能提高第一种单纯溶剂在体系中溶解度。
本发明的有益效果是:
1、本发明使用含氟有机溶剂,同时使用含氟表面活性剂,能够满足高耐压值和良好润湿性,改善体系相容性,实现高电压条件下的良好的清洗能力。
2、本发明采用含氟表面活性剂,由于含氟表面活性剂结构上的特殊性,相比普通型表面活性剂,其与含氟溶剂相容性好,改善润湿性效果好,同时对体系耐压值影响较小。
3、本发明采用的基础油,成本低,主要是馏程在140~200 ℃的烷烃,而二氯甲烷则能提高清洗能力,改善挥发性,提高阻燃性。
4、本发明含氟有机溶剂可以是一种或几种的混合物,含氟有机溶剂A可以是全氟庚烷,含氟有机溶剂B可以是含氟醚类溶剂。单纯使用含氟有机溶剂A,其在体系中溶解度小,改善耐压值效果有限。引入含氟有机溶剂B,可提高含氟溶剂A在体系中溶解度,清洗效果更佳。
5、本发明容易实施、去污能力很强且除尘彻底,其适用范围广,推广后具有良好的经济效益。
具体实施方式:
实施例一:通信设备带电清洗用高绝缘清洗剂,以重量份为准由下述组分构成:基础油65份、二氯甲烷10份、含氟有机溶剂5份、含氟表面活性剂0.1份、硅油0.5份。本实施例中,含氟有机溶剂采用两种含氟有机溶剂的混合物,分别为含氟有机溶剂A和含氟有机溶剂B;基础油为馏程在140~200 ℃的烷烃。
含氟有机溶剂A是全氟庚烷,含氟有机溶剂B可以是含氟醚类溶剂。单纯使用含氟有机溶剂A,其在体系中溶解度小,改善耐压值效果有限。引入含氟有机溶剂B,可提高含氟有机溶剂A在体系中溶解度。
本发明各组分的功能:
二氯甲烷:提高清洗能力,改善挥发性,提高阻燃性。
含氟有机溶剂:提高耐压值和阻燃性。
含氟表面活性剂:提高清洗剂润湿性,改善组分相容性。
