    环氧地坪常见的开裂方式有哪几种?如何解决?

    环氧地坪在涂装后因受各种因素的影响,不久就会产生部分断裂的现象,根据裂纹的形态(大小、深度、宽度)可分为发状裂纹、细裂纹、粗裂纹、龟裂、鳄鱼皮裂纹和玻璃裂纹等。下面环氧地坪厂家的施工人员就环氧地坪常见的三种开裂方式给大家进行了以下详细介绍,以及相应的解决方法,一起来了解一下吧!

    Due to various factors, the epoxy floor will be partially cracked soon after coating. According to the shape of cracks (size, depth, width), it can be divided into hair cracks, fine cracks, coarse cracks, turtle cracks, crocodile skin cracks and glass cracks. The following epoxy flooring factory workers on the three common ways of epoxy flooring cracking for you to carry out the following detailed introduction, and the corresponding solutions, together to learn about it! uuuuuuuuu 

    1、细裂

    1, slender

    涂膜涂装后产生肉眼不易辨认,但用十倍显微镜可明显观察到的细纹。它是由涂装内部的收缩力超过涂膜本身内聚力而引起涂膜表面的破裂。它无损于涂膜的美观,是涂膜老化的必然结果。但如果在涂装后不久就出现此种情况,那就是一种病态。

    After coating, the naked eye is not easy to identify, but fine lines can be observed by ten times microscope. It is caused by the internal force of the coating which exceeds the cohesion of the film itself and causes the rupture of the coating surface. It does not damage the appearance of the film, and is the inevitable result of the aging of the film. But if this happens soon after painting, it is a pathological condition.

    2、粗裂

    2, coarse fissure

    涂膜在涂装后不久产生明显粗裂纹,有时可见底的现象。

    The coating has obvious cracks after coating, and sometimes it can see the bottom.

    3、龟裂

    涂膜在涂装后出现形状类似龟背上纹路裂纹的现象。鳄鱼皮裂纹和玻璃裂纹也有此类似现象。

    After coating, the coating appeared to be shaped like cracks on the back of the turtle. Crocodile skin cracks and glass cracks also have similar phenomena.

    我们分析了开裂的具体原因,我们在了解了其开裂原因的同时,我们需要做的就是该怎么解决这些开裂问题。洛阳鑫和颜丽环氧地坪环氧地坪行业已经有了十几年的实际施工经验,对于环氧地坪开裂这些问题,经历的是数不胜数,解决这些问题完全没有问题。

    We have analyzed the specific causes of cracking. While we understand the causes of cracking, what we need to do is how to solve these cracking problems. Luoyang Xin and Yanli epoxy flooring have more than ten years of practical construction experience in the epoxy flooring industry. For these problems, there are countless experiences. There are no problems in solving these problems.

    环氧环氧地坪表在大多数条件下,开裂也是与配方有关的涂料损坏,是涂膜老化造成的。它不同于微裂纹和鳄裂,已不是表面问题,而是整个涂层发生破损,露出底材,因此属于严重的涂料损坏。它也是涂膜中的应力超过了涂膜本身的强度造成的。如果说微裂纹是表面应力作用的结果,那么开裂则是整个涂层的应力以及涂膜与基材之间的应力作用的结果。

    Under most conditions, the cracking of epoxy floor surface is also caused by coating damage related to formulation, which is caused by aging of coating film. Unlike microcracks and crocodile cracks, it is no longer a surface problem, but the whole coating is damaged and exposed to the substrate, so it belongs to serious coating damage. It is also caused by the stress in the coating exceeding the strength of the coating itself. If the micro-crack is the result of surface stress, then the crack is the result of the stress of the whole coating and the stress between the coating and the substrate.

    想避免开裂的话我们最好选用合适的树脂、增塑剂和颜料可以解决开裂问题。纤维状或针状的增强颜料有助于增强涂层,抗开裂。增塑树脂或增塑剂的加人也有助于软化涂层,使其有更大的延展性和弹性,减小了由于温度变化、气候循环、持续聚合反应而产生的应力。

    To avoid cracking, we'd better choose suitable resins, plasticizers and pigments to solve the cracking problem. Fibrous or needle like reinforcing pigments help to enhance coating and resist cracking. The addition of plasticizer or plasticizer also helps to soften the coating, making it more ductile and elastic, and reducing the stress caused by temperature change, climate cycle and continuous polymerization reaction.

    涂于木材上的涂料通常要比涂于钢材之上的更易开裂,这是木材的纹理造成的。当木材膨胀和收缩时,它的横向尺寸变化要比沿纹理方向大得多,因此,涂层横向受到的应力要比纵向大,开裂纹沿纹理方向呈直线型。

    Coatings applied to wood are usually more likely to crack than those applied to steel, which is caused by the texture of wood. When the wood expands and shrinks, its transverse dimension changes much more than along the texture direction. Therefore, the transverse stress of the coating is larger than that of the longitudinal direction, and the crack lines are linear along the texture direction.
