环氧地坪耐磨层脱落原因分析

添加时间:2020-05-06      来源:http://etiton.com

  金刚砂耐磨地坪的一般使用寿命为8-15年,但在很多停车场,金刚砂耐磨地坪往往在2-3年,甚至更少的时间会出现在涂层的分离损伤。
  The general service life of emery wear-resistant floor is 8-15 years, but in many parking lots, emery wear-resistant floor often occurs in 2-3 years, or even less time in the separation damage of coating.
  环氧平涂矿物合金骨料(金刚砂)表面硬化剂是由一定粒径的矿物合金骨料、特种水泥、其他外加剂和外加剂组成。
  The surface hardener of epoxy flat coating mineral alloy aggregate (carborundum) is composed of mineral alloy aggregate with certain particle size, special cement, other admixtures and admixtures.
  在初凝阶段均匀分布在混凝土表面,并经过特殊处理。因此,它与混凝土地面形成一个整体,并具有高密度和高性能耐磨地面的颜色。

  In the initial setting stage, it is evenly distributed on the concrete surface and treated specially. Therefore, it forms a whole with the concrete ground, and has the color of high density and high performance wear-resistant ground.
  防静电地板金刚砂地面应用的范围:由于金刚砂地面环氧树脂地板的性能是不同的,因此使用时必须根据环境和需要选择,环氧地板漆中使用缺乏专用车辆经常走路,没有沉重的影响,往往没有锋利的硬物体经常摩擦,腐蚀性化学物质存在的各类工业、民用和商用地板。金刚砂耐磨地板适用于各类工业、民用和商业地板经常需要承担车辆行走,经常有重物击中,经常有锋利的硬化摩擦,无腐蚀性的化学物质存在,清洁的要求不高,美容的要求不高。
  Application range of anti-static floor emery floor: because the performance of emery floor epoxy resin floor is different, it must be selected according to the environment and needs. The epoxy floor paint lacks special vehicles to walk frequently, has no heavy impact, often does not have sharp hard objects to rub frequently, and corrosive chemicals exist in various industrial, civil and commercial floors. The emery wear-resistant floor is suitable for all kinds of industrial, civil and commercial floors, which often need to bear vehicle walking, often hit by heavy objects, often have sharp hardening friction, no corrosive chemicals, low cleaning requirements and low beauty requirements.
  让我们看看停车场金刚砂耐磨地坪涂料出现这样情况的原因是:1,停车场金刚砂耐磨地坪涂料剥离破坏通常由金刚砂耐磨地坪涂料剥离损伤引起的大面积,大面积的剥离和金刚砂耐磨地板漆涂层损坏主要是两件事:一、金刚砂耐磨层结合混凝土基层界面损伤,其特点是环氧涂层脱落,混凝土基层在正常情况下,面积较大,直接原因是界面粘结强度不够;B.环氧涂层与混凝土基层表面砂浆紧密结合。破坏面出现在混凝土基层内部,破坏面位于混凝土基层的砂浆面内。这类破坏一般发生在大面积,直接原因是混凝土抗拉强度不够。停车场的金刚砂耐磨地坪涂层也有不同的膜层,主要原因是不同膜层之间的附着力不够,一般出现在局部,大面积不常见。2、金刚砂耐磨地坪涂料凸起和裂纹:金刚砂耐磨地坪涂料当地突出,主要表现为在2 ~ 5毫米直径和30 ~ 50 mm隆起的不同级别,主要原因是基层干,气体浓度低于漆膜,涂层表面吸收水分和肿块,或烤箱固化杂质不干净。涂层中出现裂纹,其特征是涂层膜的收缩和开裂,以及涂层由于基底层的裂缝而开裂。
  Let's take a look at the reasons for the following situations: 1. The peeling damage of carborundum wear-resistant floor coating in parking lot is usually caused by the peeling damage of carborundum wear-resistant floor coating, Large area peeling and coating damage of carborundum wear-resistant floor paint are mainly two things: first, interface damage of carborundum wear-resistant layer combined with concrete base course, which is characterized by epoxy coating falling off. Under normal conditions, the area of concrete base course is large, which is directly caused by insufficient bond strength of interface; B. close combination of epoxy coating and concrete base course surface mortar. The failure surface appears inside the concrete base, and the failure surface lies in the mortar surface of the concrete base. This kind of failure usually occurs in a large area, the direct reason is that the concrete tensile strength is not enough. There are also different film layers in the emery wear-resistant floor coating of parking lot, the main reason is that the adhesion between different film layers is not enough, which generally appears in local areas and is not common in large areas. 2. Diamond wear-resistant floor coating bulge and crack: Diamond wear-resistant floor coating is locally prominent, mainly manifested in different grades of 2-5mm diameter and 30-50mm bulge. The main reason is that the base is dry, the gas concentration is lower than the paint film, the coating surface absorbs moisture and lumps, or the curing impurities in the oven are not clean. Cracks appear in the coating, which are characterized by shrinkage and cracking of the coating film, as well as cracking of the coating due to cracks in the base layer.
