有關舊地坪翻新的幾種方法及技術解讀

做环氧地坪塗裝時，並不是僅對新建成的地面進行施工，如果是一些舊的环氧地坪漆地面，或是以前做過环氧地坪塗裝表面有壞塗層的地面進行塗裝時，我們則必需要先將破損掉的油漆層去掉，這個去掉破損油漆層的過程我們稱為除漆，下面正小編來為大傢介紹一下幾種有效除漆的方法及技巧。
When doing floor painting, it is not only for the newly built floor, if it is some old epoxy floor paint floor, or the surface of the epoxy floor coated with a bad coating before painting, we must first remove the damaged paint layer, the process of removing the damaged paint layer we call In addition to lacquer, the following is a small series to introduce some effective methods and techniques for removing paint.
透水地坪除漆一般可以分為兩種情況，一是將局部破損的塗膜去除，對完好的塗漠進行保留，這主要是針對於小面積破損的环氧地坪而言。另一種情況是將將整個地坪表面的塗裝全部去除，直到露出水泥素地。
Paint removal can generally be divided into two situations, one is the removal of partially damaged film, to preserve the integrity of the desert, which is mainly for small areas of damaged floors. The other is to remove all the surface of the entire floor until it is exposed to cement.
當塗裝過地坪塗料的表面出現瞭起皮、起泡、腐蝕、開裂等現象時，我們需要將這部分有質量問題地坪塗裝完全去除掉，隻要露前塗裝前的基材才可進行重新塗裝。
When skin, blister, corrosion, cracking and other phenomena appear on the surface of coated floor coatings, we need to completely remove this part of the quality problems of floor coating, as long as the substrate before dew coating can be re-coated.
在進行塗裝前要先弄清楚原地坪塗料的塗裝體系，以便選擇到合適的地坪塗料。如果上次塗裝的地坪底漆是环氧類或聚氨酯塗料，上面可以配套塗裝的塗料范圍則選擇面較寬，大部分的塗料都可以在上面直接塗裝。如果底漆采用的是單組份丙烯酸或其它類的易揮發的塗料，如果隨意的選擇地坪塗料塗裝，很容易出現咬底的情況，在進行塗裝時一定要謹慎選擇塗料。
Before painting, it is necessary to make clear the coating system of floor coatings, so as to select the appropriate floor coatings. If the last coated floor primer is epoxy or polyurethane coatings, coatings can be matched above the selection of a wide range of coatings, most of the coatings can be directly coated on top. If the primer is a single component of acrylic acid or other volatile coatings, if the optional choice of floor coating coating coating, it is easy to occur underbite, in the painting must be carefully selected coating.
四種常用的除漆方法：
Four common methods of removing paint:
1、機械除漆法
1. Mechanical lacquer removal
機械除漆指借助於一定的施工工具來進行除漆工作，如手工打磨、動力工具、拋丸、高壓力（磨料）射流等方法，都可以有效的去除舊地坪油漆層的方法。這也是美地寶最推崇的地坪除漆法。
Mechanical paint removal refers to the use of certain construction tools to remove paint work, such as hand grinding, power tools, shot blasting, high-pressure (abrasive) jet method, can effectively remove the old floor paint layer method. This is also the most popular paint removal method in the United States.
2、火焰除漆法
2, flame paint removal method
火焰除漆是指通過火焰加溫的方法使舊漆層焦軟、起泡，在此同時用刮刀進行刮鏟舊地坪漆膜。這種除漆法一般不多見。
Flame paint removal refers to the use of flame heating method to make the old paint layer soft, foaming, at the same time with a scraper to scrape the old floor paint film. This kind of paint removal is not common.
3、堿液除漆法
3, alkali paint removal method
堿液除漆法是利用堿液的腐蝕作用，使舊塗膜膨脹松軟，從而達到去除舊地坪漆膜的目的。
Alkali paint removal method is to use alkali corrosion, so that the old film expansion soft, so as to achieve the purpose of removing the old floor paint film.
4、脫漆劑脫漆
4. Paint remover.
脫漆劑是能夠溶解或溶脹塗膜的溶劑或膏狀物，主要由溶解能力強的溶劑與石蠟、纖維素等組成。在地坪塗裝行業，清除舊塗膜主要用機械的方法如手工烤鏟、拋丸等。
Paint remover is a 环氧地坪solvent or paste which can dissolve or swell the film. It is mainly composed of solvent with strong dissolving ability, paraffin, cellulose and so on. In the floor coating industry, the main methods to remove the old coating are mechanical methods, such as hand-made shovel, shot blasting, etc.
