    环氧地坪施工环氧树脂地坪与混凝土粘合不牢的原因

    2018-10-29 08:32:41 无锡盛发地坪科技有限公司 阅读

    影响到环氧地坪施工环氧树脂地坪与混凝土粘合的因素主要可以分为两块:混凝土基面的情况与环氧地坪的情况。混凝土基面的情况 程度相应的粗拙、干燥、坚实的混凝土面为最佳的混凝土基面。

    The factors affecting the adhesion of epoxy floors to concrete can be divided into two parts: the condition of concrete base and the condition of epoxy floors. The best concrete foundation surface is the coarse, dry and solid concrete surface corresponding to the degree of concrete foundation.

    1、多孔性:混凝土作为一种多孔性的地面,内部的毛细管比较适合环氧地坪油漆的浸入, 环氧树脂地坪漆渗透渗出的越好,两者的粘结机能越好,所以一般旧的混凝土地面,环氧树脂自流平地板 尤其是涂抹过其他遮盖物的基面,都要经由充分的打磨使其具备一定的粗拙度及地面孔洞开放后进行施工。

    1. Porosity: As a kind of porous ground, the inner capillary is more suitable for the immersion of floor paint. The better the penetration of epoxy floor paint, the better the bonding function of the two, so the general old concrete floor, epoxy resin self-leveling floor, especially the base coated with other covering materials. They must be fully polished to make them rough and open after surface opening-up.

    2、含水量:混凝土基面的含水量越低,粘结机能越好。

    2, water content: the lower the moisture content of the concrete base, the better the bonding function.

    3、坚实的地面。地面过于疏松,会使密封固化环氧地坪与基面没有粘结力。所以在施工前要将疏松层全部去除。

    3, solid ground. The surface is too loose, which will make the sealing and curing floors unbonded with the base surface. So before construction, remove the loose layer.

    环氧地坪材料的情况

    Situation of epoxy floor material

    1、固化反应。 耐磨地坪材料属于是反应固化型的涂料,在反应过程中放热的热量多少和产生的温度高低都对地坪漆的固化机能有很大的影响。其中固化剂是影响固化温度的主要因素,所以要想保证环氧地坪漆与基面的粘结力,必须选择合适的固化剂。

    1, curing reaction. Wear-resisting floor materials are reactive curing coatings. The amount of heat released and the temperature produced during the reaction have a great impact on the curing performance of floor coatings. The curing agent is the main factor affecting the curing temperature, so in order to ensure the adhesion between the epoxy floor paint and the substrate, we must choose the appropriate curing agent.

    2、施工工艺。当地坪漆与基面的粘接力不足时,地坪会泛起脱落的现象,而预防脱落最有效的方法就是要留意基面的处理,必须在基面有合适的粗拙、干燥的状态下才可进行地坪施工。

    2. Construction technology. When the adhesion between the floor paint and the base is insufficient, the floor will be flooded with shedding phenomenon, and the most effective way to prevent shedding is to pay attention to the treatment of the base surface, must be in the base surface has the appropriate rough, dry state before the floor construction.
