油污影响环氧地坪漆的附着,涂漆施工前应先除油。常用火焰烧、汽油洗这些危险方法,但也不易除干净,而且这种方法在许多场合下是不能采用的。建议采用以下的除油清洗剂清洗、覆盖的方法:即先将表层油污铲、刮除去粘尘土的一层,然后用慢干溶剂加壬基酚聚氧乙烯醚表面活性剂和水配制的除油剂涂刷地面,将油污乳化,吸干污水,再用除油剂清洗,再吸干,连续多次,直至地面没有油渗出来为止。这样处理的地面如已比较干净,可直接进行环氧地坪漆施工。如觉察仍有油渗出的可能,则再采用聚合物水泥砂浆层覆盖的方法,干燥硬化后再施工环氧地坪漆,可使残余油污不再渗出影响油漆施工和附着。在经过这些方法的处理后,一般来说油污大部分会被清理掉。清理掉油污后,环氧地坪漆施工就比较容易了,而且施工效果也会比较好。

专家建议,在有油污的地方进行环氧地坪漆施工时,一定要先除油污再施工。地坪漆施工前一定要把油污处理干净,否则直接影响地坪漆的涂装效果及使用寿命,油污处理(也叫脱脂)主要是指利用各种化学物质的溶解、皂化、乳化、润湿、渗透和机械等作用除去地坪漆涂装表面油污的过程。常用的材料主要是碱液、有机溶剂(稀释剂)、清洗剂(脱脂剂)。常用的清洗工艺主要有:用稀释剂擦洗、浸泡、喷射、火焰等方法,还有机械喷砂法等。碱液清洗法:是一种主要依赖于油的皂化反应除油的方法,是一种最简单、最古老的方法,在地坪漆施工过程中,该方法由于价低廉被广泛使用。但对于难皂化的油,除油效率低。可用浸渍、喷射或滚筒等工进行清洗。有机溶剂清洗法:用有机溶剂对油的溶解能力除油是一种普遍的除油方法,除油效率高,适合各种油污,一般不影响基面的物理性能,但不能同时去除无机盐和碱性物质,除油不彻底,溶剂挥发后容易残,有着火和中毒的危险,因此,所用的有机要求具有溶解力强、不宜着火、毒性小、挥发慢等性能,常用的清洗用溶剂主要有稀料、汽油、石油溶剂、松节油、甲苯、二苯和含氯溶剂等。

遇到油污可以手工擦拭:需蘸娶碱液或有机溶剂,除油时间较长,效率低,劳动条件差;但设备简单,成本低,操作灵活性大。火焰:接用喷灯等,将工件加热到300-400,使油污燃烧成碳化物,是一种古老的除油方法,除油彻底,但污染环宽,损伤物体表面,可能有残碳存在。基面的油污处理的越干净对于地坪漆的涂装效果越好,地面油污的处理干净与否直接关系到地坪漆的使用寿所以对此一定要重视。

或者用有机溶剂来清洗:用有机溶剂来对油的溶解能力除油则是一种普遍的除油的方法,它的除油效率是很高的,并且适合于各种的油污中,一般是不会影响到基面的物理性能的,但是不能同时去除无机盐和碱性的物质,除油不彻底,溶剂挥发后是很容易残留的,并且会有着火和中毒的危险的。所以我们在使用的时候,那有机一定要有溶解力强不宜着火毒性小挥发性慢等性能的有机溶剂来清洗,这也是出于一种安全考虑。

在地坪漆施工中,环氧地坪漆产品会遇到各种以油脂为基础成分的油渣,这种油渣会导致环氧地坪漆品牌产品的使用质量下降,严重的甚至会是涂膜脱离失去防护地面的作用。并且油污处理起来很困难,刹那间也不能清洁干净。对此这个问题,洁达品牌的笔者同专业人士探讨研究得出以下对策:1、针对化学性。油污能与脱脂剂发生化学反应,这可划分为“可皂化(例如动物油和植物油等)”,可用皂化、乳化和溶解作用清理;“不可皂化(例如凡士林和矿物油等)”,只能乳化、溶解或分散等作用去除。2、针对物理性。油污品可分3态,液态和半固态,粘度越高,清理的难度就越大。如果,固态油污品与液态油污品混合,形成油性颗粒掉落到环氧地坪漆品牌产品上。我们可以使用脱脂剂,使用后会使混合油污分散或悬浮,较液态的油污更容易去除。3、针对油污的极性。油污与被涂污的附着力而言,可分为极性和非极性。若环氧地坪漆品牌产品上如含有极性的油污,清理时需要要依靠化学反应和较强的机械作用力去清理。而非极性的油污较难清理。
