环氧地坪刷漆、防静电地坪漆施工听起来好像一样,都是在环氧地坪表面涂刷油漆,但实际上在施工过程中还是有很大差别的。环氧地坪刷漆是传统施工在地表层刷上一层薄薄的油漆,主要目的是为了美观,但实用性差,易脱层、起皮,脱落,不抗压,不耐磨,但价格相对普通的环氧地坪漆施工也要便宜一半还多呢。 而现代规范的环氧地坪漆施工是有多步骤的工序实现的:
The construction of epoxy floor paint and anti-static floor paint sounds like the same, they are all painted on the surface of epoxy floor, but in fact there are still great differences in the construction process. Epoxy floor paint is a traditional construction on the surface of a thin layer of paint, the main purpose is to beautiful, but poor practicability, easy delamination, peeling, peeling off, not compressive, not wear-resistant, but the price is relatively ordinary epoxy floor paint construction is also more than half cheaper. The modern standard epoxy floor paint construction is a multi-step process to achieve: 一、基材处理不同
I. Different Base Material Processing
传统涂装不重视基材处理,有时混凝土不做任何处理就涂上底漆,有的仅稍做处理,处理方式就是铲一铲,扫一扫,去除灰尘而已。
Traditional painting does not pay attention to the treatment of the base material. Sometimes the concrete is primed without any treatment. Some only do a little treatment. The treatment method is shoveling, sweeping and removing dust.
1、对混凝土地面的要求:
1. Requirements for concrete floors:
⑴ 混凝土要求平整密实,强度要求不低于C20;⑵ 地面平整度一般要求在2M范围内落差不大于2mm,如落差较大,则环氧地坪涂层需加厚以减少落差;⑶ 如需涂装的地面处于底层,地下水位较高,则混凝土底层应作防水处理;⑷ 新建混凝土干燥至少三周以上,含水率不高于8%;⑸ 也可在水磨石等底材上涂装。
(1) Concrete should be flat and compact, and its strength should be no less than C20; (2) The difference of ground roughness should be no more than 2mm in the range of 2M. If the difference is large, the floor coating should be thicker to reduce the drop; (3) If the ground to be coated is at the bottom and the groundwater level is high, the concrete bottom should be waterproof treated; (4) New construction; Concrete is dried for at least three weeks with moisture content not higher than 8%. _It can also be coated on terrazzo and other substrates.
2、基材处理方法对于新建混凝土基材,采用如下处理方式:
2. For the new concrete base material, the following treatment methods are adopted:
⑴处理目的:提高地面整体平整度,去除浮层及污物,获得均一的粗糙表面以利于涂层附着。
_Treatment purposes: To improve the overall smoothness of the ground, remove floating layer and dirt, and obtain uniform rough surface for coating adhesion.
⑵处理设备:自吸尘地面磨削机(日本进口)、真空吸尘器等。
(2) Treatment equipment: self-cleaning ground grinder (imported from Japan), vacuum cleaner, etc.
⑶要求:达到地面坚实、无砂眼、窝洞,同时要求干燥、清洁、无浮尘、油污、水泥砂粒等杂物。
(3) Requirements: to achieve a solid ground, no sand holes, caves, while requiring dry, clean, no floating dust, oil, cement sand and other impurities.
二、涂料的选择不同
2. Different Choices of Coatings
传统的地面涂装往往对涂料不进行严格选择,只采用面漆涂刷1-2道,不采用封闭底漆,或随意采用类似钢结构用底漆一样的底漆涂刷。环氧地坪漆的施工是由环氧底漆、环氧中漆、环氧腻子层、环氧面漆分层次施工,从而保证环氧地坪的耐磨性、抗压性等,又保持了传统油气环氧地坪的美观性。
The traditional floor painting often does not choose the paint strictly, only uses the top paint to brush 1-2 routes, does not use the closed primer, or uses the primer like the steel structure primer to brush at will. The construction of epoxy floor paint is divided into epoxy primer, epoxy medium paint, epoxy putty layer and epoxy top paint, which ensures the wear resistance and compression resistance of epoxy floor, and maintains the beauty of traditional oil and gas floor.
三、现代化地坪漆涂装方式有了较大创新
3. Great innovations have been made in the painting methods of modern floor paint
传统的环氧地坪漆涂装多采用喷、刷或辊的方式施工,地坪漆根据地坪涂料的施工性能和涂装要求,对涂装方式进行了创新,除了传统的喷、刷、辊涂方式外,还采用了刮板刮涂,锯齿镘刀镘涂、抹光机抹涂,高压无气喷涂等施工方式,保证施工均匀、避免出现流挂、刮痕等不良现象。
Traditional epoxy floor coatings are mostly constructed by spraying, brushing or roller. According to the performance and requirements of floor coatings, floor coatings are innovated. Besides the traditional spraying, brushing and roller coating methods, scraper scraping, sawtooth trowel spraying, polishing machine spraying, high pressure airless spraying and so on are also used. The construction method ensures the uniformity of the construction and avoids the harmful phenomena such as hanging and scratching.
