随着社会的不断发展，环氧地坪涂料制造和涂装技术也有了很大进步，和传统地面涂装技术相比，统地面涂装技术相比，有以下不同： 基材处理不同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。

With the continuous development of society, epoxy floor coating manufacturing and painting technology has also made great progress. Compared with traditional surface painting technology, traditional surface painting technology has the following differences: the treatment of substrates is different from traditional painting, which does not pay attention to the treatment of substrates, sometimes concrete is coated with primer without any treatment, and some only do a little. The way to deal with it is to shovel, sweep and remove the dust. 1、对混凝土地面的要求： 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. Requirements for concrete floor: _Concrete requires flat and compact, strength requirement is not less than C20; _Ground smoothness generally requires a drop of less than 2mm in the range of 2M; If the drop is large, epoxy floor coating needs to be thickened to reduce the drop; _If the ground to be coated is in the bottom layer and the groundwater level is high, concrete will be required. The bottom should be waterproof. _New 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：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。 ⑵处理设备：自吸尘地面磨削机、真空吸尘器等。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。⑷工序：采用地面磨削机整体打磨一遍—吸尽灰尘—修补大的窝洞、凹陷及裂缝。对于旧漆地面，如旧漆层附着不牢，需采用地面铣刨机整体去除旧漆层(1mm厚度以下旧漆层可采用金刚切削刀处理)，因处理成本高，如客户不要求整体去除旧漆，则只去除松动旧涂层，去除表面油污及杂物。科学的环氧地坪涂装十分重视基材处理，并采用专业的处理机械进行处理，因良好的基材处理是取得优异环氧地坪工程的前提，采用专业环氧地坪磨削机处理地面有以下优点：

2. For the new concrete base material, the following treatment methods are adopted: (1) The purpose of the treatment is to improve the overall smoothness of the ground, remove floating layer and dirt, and obtain uniform rough surface to facilitate the adhesion of the coating. (2) Treatment equipment: self-cleaning ground grinder, vacuum cleaner, etc. (3) Requirements: to achieve a solid ground, no sand holes, caves, while requiring dry, clean, no floating dust, oil, cement sand and other impurities. (4) Procedure: Use the ground grinder to grind the whole once - absorb the dust - repair the large holes, depressions and cracks. For the old lacquer floor, if the old lacquer layer is not firmly adhered, the whole old lacquer layer needs to be removed by ground milling machine (the old lacquer layer below 1 mm thickness can be treated by diamond cutter). Because of the high cost of treatment, if the customer does not require the whole removal of the old lacquer, only loose old coatings will be removed, and surface oil and impurities will be removed. Scientific flooring coating attaches great importance to the treatment of base materials and adopts professional treatment machinery. Because good base material treatment is the prerequisite for achieving excellent flooring engineering, the use of professional epoxy floor grinder to treat the ground has the following advantages:

⑴可去除基材表面强度差的浮尘，以利封闭底漆渗透进基材，增强涂层与基材的附着力。

(1) It can remove the floating dust with poor surface strength, so as to facilitate the penetration of the sealing primer into the substrate and enhance the adhesion between the coating and the substrate.

⑵由于专业设备金刚研磨刀的特殊设计，打磨后基材表面有均一的粗糙度，可增强涂层与基材的附着力。

(2) Because of the special design of the professional equipment diamond grinding tool, the surface of the substrate after grinding has uniform roughness, which can enhance the adhesion between the coating and the substrate.
