如何判断环氧地坪漆涂膜老化?怎么预防保养

发布日期:2019-07-06 浏览次数:41

根绝每一个特征来判断环氧地坪漆涂膜的老化程度,并采取相应的措施。在前期失光和变色阶段,可以在失光或者变色的部位重新涂刷环氧地坪漆面漆,重塑它的装饰性效果。但是在粉化阶段,丧失的不仅是装饰性效果,其实用性能也随之下降,这时就需要彻底去掉涂层,重新涂装。每一个东西的衰老都是有迹可循的,环氧地坪也一样,环氧地坪漆的涂膜老化也是一个循序渐进的过程,从下面几个特征中我们就可以判断:

The aging degree of epoxy floor coatings can be judged by eliminating each characteristic and corresponding measures should be taken. In the early stage of light loss and discoloration, epoxy floor paint can be re-painted on the part of light loss or discoloration, and its decorative effect can be reconstructed. But in the powdering stage, not only the decorative effect is lost, but also its practical performance is declining. At this time, it is necessary to completely remove the coating and re-coat. Everything's aging is traceable, and so is epoxy flooring. The aging of flooring paint is also a gradual process. We can judge from the following characteristics:

环氧地坪

一、失光

I. Loss of Light

失光是环氧地坪漆涂膜老化的最初的特征,环氧地坪表面由于长期受到紫外线的照射,引起了光化学反应,使环氧树脂成分发生降解,逐步丧失原有光泽,直至发展成全部失光。

Loss of gloss is the initial feature of the ageing of epoxy floor paint film. The surface of the floor is exposed to ultraviolet radiation for a long time, which causes photochemical reaction, which degrades the epoxy resin composition and gradually loses its original gloss until it develops into total loss of gloss.

环氧地抨漆涂膜的光泽是体现环氧地坪装饰性效果的重要指标。涂膜失光,就没有装饰性可言了。

The gloss of epoxy flooring paint film is an important index to reflect the decorative effect of epoxy flooring. If the coating is not glossy, there will be no decoration.

二、变色

II. Discoloration

造成环氧地坪漆涂膜变色有很多因素,但是涂膜变色却是环氧地坪漆涂膜开始老化的另一特征。从正常的颜色变成有的发白、有的发黄,或者有的地方颜色变深,有的变浅等,这都是变色。变色后的环氧地坪严重影响其装饰效果。

There are many factors that cause the discoloration of the epoxy floor paint film, but the discoloration of the film is another characteristic of the beginning of the aging of the epoxy floor paint film. From the normal color to some whitening, some yellowing, or some places darker, some lighter, and so on, these are all discoloration. The decorated epoxy floor seriously affects its decorative effect.

三、粉化

3. Powdered

如果说前两个特征是环氧地坪老化的初始特点,那么粉化就是环氧地坪涂膜已经老化的象征。粉化的原因是因为其受到紫外线的辐射以及氧气的相互作用,导致树脂分子链的交联降解,使树脂与颜料颗粒之间分离,出现脱粉现象。

If the first two characteristics are the initial characteristics of epoxy floor ageing, then pulverization is the symbol of the aging of epoxy floor coating. The reason of powdering is due to the interaction of ultraviolet radiation and oxygen, which leads to the degradation of resin molecular chains, separation between resin and pigment particles, and dedusting.

一般环氧地坪出现粉化现象,是在环氧地坪漆涂膜发生了非常严重的失光和变色后,也就是说此时的环氧地坪,不仅已经完全丧失了装饰性,而且它的实用性能也开始降低,标志着涂膜老化已到严重阶段。

Generally, the powdering of epoxy flooring occurs after the film of epoxy flooring paint has undergone a very serious loss of light and color, that is to say, at this time, the epoxy flooring not only has completely lost its decorative properties, but also its practical performance has begun to decline, indicating that the aging of the film has reached a serious stage.
