    怎么解决环氧地坪漆施工粉尘的问题?

    环氧地坪漆施工过程中粉尘对人体的危害在环氧地坪漆涂料施工过程中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。1.选择合适的地板涂料和工业施工方法 ?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。2.防止粉尘扩散 ?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。

    The hazard of dust to human body during the construction of epoxy floor paint is related to its particle diameter. Dust with a particle diameter of 50 fallacies can almost be completely blocked in the nose, throat, trachea and bronchus. Dust with 10-15 fallacies can be blocked in the upper respiratory tract. Dust with 5-10 fallacies can reach the lungs. 1. Choosing suitable floor coatings and industrial construction methods? 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. Preventing dust diffusion? 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. Jotafloor Topcoat 

    二、粉尘的来源主要有三个方面,分别是粉末涂料、涂层打磨和机械除锈。

    Secondly, the sources of dust are mainly three aspects: powder coatings, coating grinding and mechanical rust removal.

    1.粉末涂料 ?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。

    1. Particle diameter of powder coatings? Powder coatings are mostly 10-90 fallacies, of which 60-70% are 30-40 fallacies. This kind of dust is most harmful to operators in powder spraying room.

    2.涂层打磨 ?在环氧地板工业环氧地坪施工涂装过程中,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。

    2. Coating polishing? In the process of coating of epoxy flooring industrial floor construction, the paint film often needs polishing treatment. The dust particle size of the paint layer polishing 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, causing great harm.

    3.机械除锈 ?机械除锈主要是去除地板上的金属氧化皮,混凝土地板污垢和旧地坪涂料,其中地板除锈施工中会用到工具除锈、喷砂、喷(抛)丸等环氧地坪施工方式,这些环氧地坪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。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。

    3. Mechanical rust removal? 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 epoxy floor construction methods will be used. These epoxy floor 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. In order to reduce the influence of silica dust produced by abrasives, the content of silica in abrasives is generally controlled. It is strictly forbidden to use more than 70% quartz sand when sandblasting.
