    环氧地坪施工前基层去除油污的方法

    环氧地坪基层处理的物理方法如人工机具打磨,采用钢丝刮、刮刀或者小型机具清除表层上的污物,抛丸机械进行喷砂处理,还可以使用高压水冲洗法和火焰法去除油污。 环氧地坪基层处理的化学方法如碱性除油法:利用高PH的碱液,溶解和分散油污进行清洗,这是一种传统的方法,简单易行,但是效率低,,对周围的环境有一定的影响,常用的酸盐累等。 表面活性剂:较稀的溶液,就能使油污得到较好的浸湿,渗透、乳化、分散等。利用这些作用可有效的除去油污物,在室温下进行地面清理油污是一种较为安全经济的技术措施。起决定性作用是乳化作用和机械作用,不耽误环氧地坪的打磨施工工序有机溶剂除油法:采用有机溶剂除油是一种普遍应用的方法,除油效率高,适用面广,这种方法不能用在通风不良的场合,若用需强化通风。因溶剂挥发造成对施工人员身体伤害和周围的环境的污染。常用的清洗溶剂主要有煤油、石油溶剂、二甲苯及含氯溶剂。采用单一有机溶剂效果有限,常在其中配入一些乳化剂,非离子型表面活性剂等。这样除油溶解油污作用外还增加了乳化剂的分散作用,使无锡富康环氧地坪施工的基层除油污效率大大提高。

    Physical methods of epoxy floor base treatment such as artificial tools grinding, using wire scraper, scraper or small tools to remove the surface of the dirt, shot blasting machine for sandblasting treatment, but also can use high-pressure water washing and flame method to remove oil stains. Chemical methods such as alkaline deoiling for epoxy floor base treatment: using high PH alkali solution, dissolving and dispersing oil dirt for cleaning, this is a traditional method, simple and feasible, but inefficient, has a certain impact on the surrounding environment, commonly used acid accumulation, etc. Surfactant: thinner solution, can make the oil get better soak, penetration, emulsification, dispersion and so on. Using these functions can effectively remove oil dirt and clean oil dirt on the ground at room temperature is a relatively safe and economical technical measure. The decisive role is the emulsification and mechanical role, do not delay the epoxy floor grinding construction process of organic solvent deoiling method: the use of organic solvent deoiling is a universal method, deoiling efficiency, wide range of application, this method can not be used in poor ventilation occasions, if need to strengthen ventilation. The physical and environmental pollution caused by solvent evaporation is harmful to the construction workers. Commonly used cleaning solvents are kerosene, petroleum solvents, xylene and chlorinated solvents. The effect of using a single organic solvent is limited, and some emulsifiers, non-ionic surfactants and so on are often mixed into it. In this way, besides oil dissolving oil pollution, the dispersing effect of emulsifier is also increased, which greatly improves the oil pollution removal efficiency of Wuxi Fukang floor construction.
