    如何应对施工环氧地坪时遇到的粉尘

    2018-10-26 07:25:36 无锡盛发地坪科技有限公司 阅读

    不管是在炎热的夏天还是在寒冷的冬天,只要接到环氧地坪订单,我们的工程部人员都要立即投入工作。有些客户还会要求在节假日期间施工;有时候为了赶工期,晚上也需要加班。所以工程部是我们环氧地坪公司最辛苦的群体。不仅如此,在施工过程中产生的粉尘还会对人体有一定的影响,那么,可以采取哪些防护措施减少粉尘对身体的危害呢?在涂装环氧地坪的过程中,粉尘的来源主要有三个方面,分别是涂层打磨、机械除锈、和粉末涂料。

    Whether in the hot summer or in the cold winter, as long as we receive an order for epoxy floor, our engineering staff must immediately put into work. Some customers will also require construction during holidays. Sometimes, overtime is necessary for the rush hour. So the engineering department is the most difficult group of our floor companies. Not only that, the dust produced in the construction process will have a certain impact on the human body, then, what protective measures can be taken to reduce the harm of dust to the body? In the process of painting epoxy floors, the sources of dust mainly have three aspects, namely, coating grinding, mechanical derusting, and powder coatings.

    1、涂层打磨

    1. Coating grinding

    在施工环氧地坪前要对素地进行进磨,而且每做完一道工序,固化后,还需要打磨涂层,才能继续下一道工序。打磨处理时产生的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,细的微粒子会进入肺部气泡,对人体的危害较大。

    Before the construction of epoxy floors, the plain ground should be grinded, and after each process is completed, the curing process needs to be grinded and coated to continue the next process. The particle size of the dust produced by polishing treatment is relatively small, the suspension time in the air is long, and it is easy to inhale into the body. Fine particles will enter the pulmonary bubble, which is harmful to the human body.

    2、机械除锈

    2, mechanical rust removal

    去年我们在南通一家工厂的钢板平台上做过环氧地坪,为了增强环氧树脂层与钢板的附着力,先要将钢板上的金属氧化皮去除;有些混凝土地板污垢和旧环氧地坪涂料也是需要先去除的。在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。

    Last year we did epoxy floor on the steel platform of a factory in Nantong. In order to enhance the adhesion of epoxy resin layer to steel plate, the metal oxide scale on the steel plate should be removed first; some concrete floor dirt and old floor coating also need to be removed first. Tool rust removal, sand blasting, shot blasting and other construction methods will be used in the construction of the ground rust removal. These construction methods will produce a lot of dust. At the same time, the abrasion of grinding discs in the process of mechanical use also produces dust of abrasive particles.

    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 abrasive, the content of silica in abrasive is generally controlled. It is forbidden to use more than 70% quartz sand when blasting.

    3、粉末涂料

    3. Powder coatings

    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。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 particle diameters of powder coatings are mostly 10-90 fallacies, of which 60-70% are 30-40 fallacies. This kind of dust is most harmful to the operators in the powder spraying room. The hazards of dust to human body are related to the particle diameter. The dust with a particle diameter of 50 fallacies can be almost completely blocked in the nose, throat, trachea and bronchi, 10-15 fallacies can be blocked in the upper respiratory tract, and 5-10 fallacies can reach the lung.

    看来粉尘对环氧地坪施工人员的危害要引起我们的关注,有什么安全防护措施呢?

    It seems that the hazards of dust to the construction personnel of epoxy floor should arouse our concern. What are the safety precautions?

    1、选择合适的环氧地坪材料和施工方法

    1. Choose suitable epoxy floor materials and construction methods.

    这是消除或减少尘粉的最有效的措施。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,尽可能地选用湿式作业。

    This is the most effective measure to eliminate or reduce dust. 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 be mechanical rust removal, as far as possible to choose wet operation.

    2、防止粉尘扩散

    2. Prevent dust dispersion.

    可采用多种措施,如通风除尘。对于施工者,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。

    Many measures can be adopted, such as ventilation and dust removal. For the builder, should wear dust masks, oxygen helmet and work clothes and other protective equipment to protect, as far as possible to reduce the hazards of dust.

    虽然地坪施工环境恶劣,但我们采取了一些防护措施后,可以把危害降到最低,这样一来,既能保证环氧地坪顺利完工,又保证了施工人员的身体健康。

    Although the construction environment is bad, but we have taken some protective measures, the harm can be minimized, in this way, both to ensure the smooth completion of the epoxy floor, but also to ensure the health of the construction personnel.
