    介绍环氧地坪施工过程中的粉尘如何处理和防范?

    我国的环氧地坪涂料产业始于20世纪90年代末初期,国外的环氧地坪涂料技术进入中国,逐渐被我国的涂料研究院所和企业引进、吸收、改进,形成我国特色的环氧地坪涂料市场。随着我国经济的快速发展,特别是医药、化工、电子等行业的高速增长,带动环氧地坪行业的市场快速增长,涂料品种也日渐丰富,产品性能不断提高。由于今年来,涂料产品的环保性逐渐得到重视,环氧地坪向无溶剂或高固体分涂料在厚涂型涂装体系中被广泛应用。

    China's epoxy floor coatings industry began in the late 1990s. Foreign epoxy floor coatings technology entered China and was gradually introduced, absorbed and improved by China's paint research institutes and enterprises, forming a unique floor coatings market in China. With the rapid development of China's economy, especially the rapid growth of pharmaceutical, chemical, electronic and other industries, the market of epoxy flooring industry is growing rapidly, and the variety of coatings is becoming more and more abundant, and the performance of products is constantly improving. In recent years, environmental protection of coatings products has been paid more and more attention. Solvent-free or high solid coatings have been widely used in thick coating systems.

    我们经常会遇到环氧地坪施工中有粉尘,这时我们该怎么弄,如果你遇到过这种情况又不知道怎么处理的話,下面就看看如何处理的。

    We often encounter dust in the construction of epoxy flooring. What should we do at this time? If you encounter this situation and don't know how to deal with it, let's see how to deal with it. 粉末涂料的颗粒直径大多在10~90谬,其中颗粒直径在30~40谬的占60%~70%,这类粉尘对喷粉室内的操作人员危害最为严重。

    Particle diameters of powder coatings are mostly between 10 and 90 fallacies, of which 60% to 70% are between 30 and 40 fallacies. This kind of dust is most harmful to operators in powder spraying room.

    粉尘对人体的危害与其颗粒直径有关,颗粒直径50谬的粉尘几乎可以完全被阻留在鼻、喉、气管、大支气管内,10~15谬的粉尘能被阻留在上呼吸道内,5~10谬的粉尘则能达到肺内。

    The harm of dust to human body is related to its particle diameter. Dust with 50 fallacies of particle diameter can almost be completely blocked in nose, throat, trachea and bronchus. Dust with 10-15 fallacies can be blocked in upper respiratory tract. Dust with 5-10 fallacies can reach lungs.

    涂层打磨在环氧地坪工业涂装过程中,漆膜往往需要打磨处理,漆层打磨的粉尘粒度比较细小,在空气中的悬浮时间长,容易吸入到体内,细微的粒子能进入肺部气泡,危害较大。

    In the process of coating polishing in epoxy flooring industry, the paint film often needs polishing treatment. The particle size of the polished dust is relatively small, the suspension time in the air is long, and it is easy to inhale into the body. Fine particles can enter the pulmonary bubbles, which is harmful.

    机械除锈主要是去除地坪上的金属氧化皮,混凝土地板污垢和旧地坪涂料,其中地坪除锈施工中会用到工具除锈、喷砂、喷(抛)丸等施工方式,这些施工方式会产生大量的粉尘。同时机械使用过程中磨碟的磨损,也会产生磨料颗粒的粉尘。

    Mechanical rust removal is mainly to remove the metal oxide skin on the floor, concrete floor dirt and old floor paint. In the floor rust removal construction, tools rust removal, sand blasting, shot blasting and other construction methods will be used. These construction methods will produce a lot of dust. At the same time, abrasive particles will also be produced by abrasive disc wear in the process of mechanical use.

    为了减少磨料产生的二氧化硅粉尘的影响,一般控制磨料中的二氧化硅的含量,喷砂时严禁使用超过70%的石英砂。

    In order to reduce the influence of silica dust produced by abrasives, the content of silica in abrasives is generally controlled. It is strictly prohibited to use more than 70% quartz sand when sandblasting.

    防尘安全措施:

    Dust-proof safety measures:

    (1)选择合适的环氧地坪地坪涂料和工业施工方法

    (1) Choosing suitable epoxy floor coating and industrial construction method

    这是消除或减少尘源的最有效的措施。主要包括:生产配料时尽可能地实现机械化;尽量采用化学方法除锈;必须进行机械除锈时,要尽可能地选用湿式作业。

    This is the most effective measure to eliminate or reduce dust sources. Mainly include: the production of ingredients as far as possible to achieve mechanization; as far as possible to use chemical methods of rust removal; must carry out mechanical rust removal, as far as possible to choose wet operation.

    (2)环氧地坪防止粉尘扩散

    (2) Epoxy Floor to Prevent Dust Diffusion

    可采用多种措施,如通风除尘等。对于操作者,应佩戴防尘口罩、可通氧气的头盔和工作服等防护用具进行防护,尽量减少粉尘的危害。

    Various measures can be adopted, such as ventilation and dust removal. For operators, they should wear protective devices such as dust masks, oxygen-permeable helmet and work clothes to protect them, so as to minimize the hazards of dust.
