厂家对旧环氧地坪漆漆膜修补技巧分析

环氧地坪漆在使用过程中可能会逐渐出现老化、脱落、开裂的现象,或因长期磨损造成涂膜破坏,影响环氧地坪的正常使用,这时候就需要对旧环氧地坪漆漆膜进行修补处理,修补时需注意以下几点技巧。①当涂过漆的表面出现了腐蚀、起皮、起泡、开裂、起鳞或全面破裂的现象时,应把损坏的涂膜完全除去,直到露出裸露基体表面,再按照环氧地坪漆施工工艺重新涂装。涂装前必须弄清原涂装涂料的配套体系,严格按照涂料配套进行。检查被保留涂膜确无缺陷后,确定涂料品种。若底漆为环氧或水性聚氨酯地坪类涂料,可保留完好涂膜,上面需配套涂装的涂料的选择范围则较宽,大多数涂料都可以直接加涂。但如果是单组分丙烯酸、氯化橡胶等挥发干燥的涂料,则很容易出现咬底等问题,加涂时一定要选择合适的涂料。

Epoxy floor paint may gradually appear aging, peeling, cracking in the use process, or film damage caused by long-term wear and tear, affecting the normal use of the floor. At this time, it is necessary to repair the old floor paint film. The following skills should be paid attention to when repairing. When corrosion, peeling, foaming, cracking, scaling or overall cracking occur on the painted surface, the damaged coating should be completely removed until the exposed surface of the substrate is exposed, and then re-coated according to the construction technology of epoxy floor paint. Before painting, the matching system of the original coatings must be clarified and carried out strictly in accordance with the matching system of the coatings. After checking that there is no defect in the retained film, the paint variety is determined. If the primer is epoxy or waterborne polyurethane floor coatings, it can retain a good film, and the choice range of coatings that need to be matched on it is wider. Most coatings can be directly coated. However, if it is volatile and dry paint such as acrylic acid and chlorinated rubber, it is easy to have bottom biting problems, so it is necessary to choose the appropriate paint when applying. 

②旧漆膜过厚、发脆或与新设计的涂料不适应、不配套,应予以除去。

(2) The old paint film is too thick, brittle or not suitable for the newly designed paint, which should be removed.

③将旧漆膜除去失效部分,直到完好、坚硬、附着良好的漆膜,其下不得有锈或起泡,与底材附着力很高,不能被插入其底下的钝的刀片起层。漆膜表面需除尘、油和其他附着污物。

(3) Remove the invalid part of the old paint film until it is intact, hard and well-adhered. There must be no rust or bubbles under it. It has a high adhesion to the substrate and can not be inserted into the blunt blade under it. Dust removal, oil and other attachments are required on the surface of the paint film.

④留在区域边缘准备再涂的牢固附着的漆膜必须加工成羽状,以使再涂装表面具有光滑的外观。为了增强与新涂料的附着强度,一般可将旧漆膜打毛处理。

(4) The firmly adhered paint film left at the edge of the area for re-coating must be processed into pinnate shape to make the re-coated surface have a smooth appearance. In order to enhance the adhesion strength with the new coatings, the old coatings can generally be wooled.

⑤进行再涂装所用的地坪漆材料一般最好与最初涂覆所用的材料相同。可在旧漆膜上涂覆符合配套原则的其他品种涂料,但需预先在局部做实验。如环氧做底漆,可在其上涂装各种品种的涂料,但为防止附着力不佳,可加涂“过渡层”等。

(5) The floor paint material used for re-coating is generally the same as the material used for the initial coating. Other kinds of coatings which conform to the matching principle can be coated on the old paint film, but the local experiments should be done in advance. If epoxy is used as primer, it can be coated with various kinds of coatings, but in order to prevent poor adhesion, it can be coated with "transition layer" and so on.
