    环氧地坪为什么裂缝?解决裂缝处理的三大技巧

    修复环氧地坪裂缝关键找到基面裂缝的原因、判断基面裂缝的类别、选择合适的修复材料和工艺方能根本性的解决问题。建设好的环氧地坪出现裂缝事故,修复难度较大、须动用的设备、耗费的人工、修复成本较高,所以在建设环氧地坪前的基面修复处理尤为关键。常见的环氧地坪施工基层类型有混凝土地面、水泥砂浆地面、水磨石等地面,具有来源广、粘度低、可灌性好、扩散能力好、施工方便、较高的机械强度,并能抵抗混凝土所遇到的大多数化学侵蚀的环氧地坪漆在施工过程中,可能会有裂缝现象的发生。

    The key to repairing epoxy floor cracks is to find out the causes of base cracks, to judge the types of base cracks, and to select appropriate repairing materials and processes。 Cracks occur in the built epoxy floors, which are difficult to repair, equipment to be used, labor-consuming and high cost of repair。 Therefore, it is particularly critical to repair the foundation before the construction of the epoxy floors。 Common types of base course for floor construction are concrete floor, cement mortar floor and terrazzo floor, which have wide sources, low viscosity, good grouting ability, good diffusion ability, convenient construction, high mechanical strength, and can resist most chemical erosion encountered by concrete。 Epoxy floor paint may be used in construction process。 There will be cracks。

    修补裂缝主要采用环氧树脂材料,漆是以溶剂型体系为主,溶剂可能会对其它一些修补材料的性能产生影响,可采用无溶剂环氧树脂体系对修补好的基层进行封闭,可不受影响。

    Epoxy resin is mainly used to repair cracks. Solvent-based system is the main type of floor paint. Solvent may affect the performance of other repair materials. Solvent-free epoxy resin system can be used to seal the repaired base without affecting it.的裂缝处理大体上分为三类

    Fracture treatment of epoxy floor can be divided into three categories.

    1、施工缝处理。

    1。 Construction joint treatment。

    施工缝不是真实存在的“缝”,是按设计要求或施工需要后浇筑混凝土超过初凝时间与先浇筑的混凝土之间存在一个结合面。

    Construction joints are not real "joints", but a joint between concrete poured after exceeding initial setting time and concrete poured first according to design requirements or construction needs.

    2、温度应力裂缝处理。

    2. Treatment of temperature stress cracks.

    在混凝土地坪施工过程中出现较多的是温度应力裂缝,产生这种裂缝的主要原因是由于基础温差和混凝土内外温差过大或由于其它原因产生的应力释放,根据表现形式的不同又可分为表面裂缝、深层裂缝、贯通裂缝三种。在一定条件下,表面裂缝会发展成深层裂缝,深层裂缝也会发展成贯穿裂缝,因此若不及时对裂缝进行修复,将会直接影响到的装饰效果。

    Temperature stress cracks often occur in the construction of concrete floor. The main causes of these cracks are the excessive temperature difference between the foundation and the inside and outside of the concrete or the stress release caused by other reasons. According to the different manifestations, they can be divided into surface cracks, deep cracks and through cracks. Under certain conditions, surface cracks will develop into deep cracks and deep cracks will develop into penetrating cracks. Therefore, if cracks are not repaired in time, it will directly affect the decorative effect of epoxy floor.

    3、伸缩缝处理。

    3. Treatment of expansion joint.

    根据结构布置、地质条件及施工布置,施工强度等在结构物中设置的横向缝,为满足结构变形的要求,缝面间一般不应有刚性填充物。因伸缩缝需满足整体建筑物的应力变化,所以对于伸缩缝处理需用弹性材质,外面铺设金属板材进行保护。

    According to the structure layout, geological conditions and construction layout, construction intensity and other transverse joints in the structure, in order to meet the requirements of structural deformation, there should be no rigid filler between joints。 Because the expansion joints need to meet the stress changes of the whole building, elastic materials are needed for the treatment of expansion joints, and metal sheets are laid outside to protect them。

    上面说到的三种环氧地坪防腐漆裂缝方式,伸缩缝和施工缝是为满足混凝土应力改变而人为设置的,温度应力裂缝是因为混凝土自身应力改变而发作的。

    The above mentioned three kinds of epoxy floor anticorrosive paint cracks, expansion joints and construction joints are set artificially to meet the change of concrete stress, and temperature stress cracks occur because of the change of concrete stress.
