    地坪漆施工过程中粉尘的危害及防护措施
    来源:http://www.jndmzp.com   时间:2015-1-15 11:44:20
    环氧地坪涂装作业中,粉尘的来源主要有三个方面,分别是机械除锈、涂层打磨和粉末涂料。
    Epoxy floor paint job, the dust source mainly has three aspects, respectively is mechanical cleaning, polishing and coating of powder coatings. 
    (1)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。
    (1) mechanical descaling is mainly to remove metal oxide coating on the floor, dirt and the old floor coating concrete floor, the floor cleaning tools are used in the construction, sandblasting, derusting spray (cast) pill construction way, such as the construction way will produce large amounts of dust. Mechanical grinding disc wear in use process at the same time, also can produce abrasive particles of dust. 
    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 the abrasive, generally control the silica content of abrasive, sand blasting, more than 70% of silica sand is strictly prohibited. 
    (2)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。
    (2) coating. In the process of industrial coating epoxy floor paint, paint film is often need to deal with the grinding, polishing paint layer of dust particle size is small, suspended in the air long and easily inhaled into the body, fine particles can enter the lungs bubbles, harm is bigger. 
    (3)粉末涂料的颗粒直径大多在10-90μ,其中颗粒直径在30-40μ的占60%-70%,这类粉尘对喷粉室内的操作人员危害为严重。
    (3) most of the powder coating grain diameter in 10-90 mu, including grain diameter in 30-40 mu of 60% - 70%, this kind of dust to the operation of the powder spraying indoor personnel most serious harm. 
    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,10-15μ的粉尘能被阻留在上呼吸道内,5-10μ的粉尘则能达到肺内。
    Dust harm to human body and its associated particle diameter, particle diameter of almost 50 goes to dust can completely be trapped within the nose, throat, trachea, bronchi, 10-15 mu of dust can be trapped inside the upper respiratory tract, 5-10 mu of dust can reach the lungs. 
    防尘安全措施
    Dust prevention safety measures 
    (1)选择合适的地坪涂料和工业施工方法
    (1) to choose the appropriate floor coating and industrial construction method 
    这是消除或减少尘源的有效的措施。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 measures to eliminate or reduce dust source. Mainly includes: production ingredients as much as possible to realize mechanization; By adopting the method of chemical derusting as far as possible; Must be mechanical descaling, want to choose wet homework as much as possible. 
    (2)防止粉尘扩散
    (2) to prevent the spread of the dust 
    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。
    Can use a variety of measures, such as ventilation and dust removal, etc. For the operator, should wear dust mask, through oxygen protective helmets and overalls and other protective equipment, as far as possible to reduce the harm of dust.
