讓你知道环氧地坪漆塗膜老化的過程

环氧地坪漆漆膜老化過程不是一觸而就的，是一個循序漸進的變化過程，現在就由輕到重為您詳細介紹下环氧地坪漆塗膜老化的三個特征：一、失光：失光是环氧地坪漆塗膜老化的最初特征，由於环氧地坪漆塗膜受太陽光中紫外線照射的影響， 引起光化學反應，使环氧樹脂成分發生降解，逐步喪失原有光澤，直至發展成全部失光。环氧地坪漆塗層光澤是裝飾性环氧地坪漆塗膜的重要指標，膜層一旦失去光澤(原始無光澤塗層除外)就無裝飾性可言，所以通過环氧地坪漆塗料塗裝，能使环氧环氧地坪漆塗膜達到光彩照人，豐滿度好，鮮映性極佳，不僅僅關系到环氧环氧地坪漆塗料的正確選擇，也是衡量环氧地坪漆塗裝工藝水平的重要指標之一。
The ageing process of epoxy floor paint film is not a touch-by-touch process, but a gradual process of change. Now we will introduce three characteristics of the ageing process of epoxy floor paint film in detail from light to weight. First, loss of light: loss of light is the initial feature of the ageing of epoxy floor paint film, because the epoxy floor paint film is purple in sunlight. The influence of external irradiation causes photochemistry reaction, which degrades the epoxy resin composition and gradually loses its original luster until it develops into total loss of luster. The gloss of epoxy floor paint coating is an important index of decorative epoxy floor paint coating. Once the film loses its gloss (except the original glossy coating), it has no decorative property. Therefore, the epoxy floor paint coating can achieve glossy, full and bright, not only related to the ring, but also through the epoxy floor paint coating. The correct choice of oxygen floor paint is also one of the important indicators to measure the coating technology level of epoxy floor paint. 二、變色
Two. Discoloration
這也是环氧地坪漆塗膜開始老化的一種較明顯的征兆。环氧地坪漆塗膜從正常的顏色發牛色相 或色澤的改變，有的變深，有的變淺，有的發暗，有的白色變黃，有的紅的 變粉色或變淺等，這些都屬於變色。其原因是由於光化學反應的結果，對色漆來說，其變色與樹脂的性質有一定關系，但主要還是取決於選用的顏料的性質，不同顏料有不同的光敏性，由此顯示出不同的保色性。
This is also a more obvious s彩色沥清地坪ign of aging of epoxy floor paint film. Epoxy floor paint film changes from normal color to cattle color or color, some darkens, some lightens, some darkens, some whites turn yellow, some Reds turn pink or light, and so on, which belong to discoloration. The reason is that the photochemical reaction results in the discoloration of the paint, which has a certain relationship with the properties of the resin, but mainly depends on the properties of the selected pigments. Different pigments have different photosensitivity, which shows different color retention.
三、粉化
Three. Pulverization
粉化是环氧地坪漆塗膜老化逐步深化的特征，其原因主要是受太陽光紫外線的輻射和氧的存在下相互作用引起樹脂分子鏈的交聯或降解，促使樹脂與顏料顆粒之間的分離，出現脫粉現象。其次是與顏料的性質、晶形也有很大關系。
Powdered epoxy floor coatings are characterized by the gradual deepening of aging. The main reason is that the interaction between ultraviolet radiation and oxygen causes the crosslinking or degradation of resin molecular chains, which leads to the separation of resin and pigment particles and the appearance of dedusting phenomenon. Secondly, it is closely related to the nature and shape of pigment.
粉化現象是环氧地坪漆塗膜發生嚴重失光或完全失光之後才會有的。也就是說此時的塗膜，不僅已完全喪失瞭裝飾特性，而且它的防護性能也已開始遭到瞭破壞，標志著塗膜老环氧地坪化已趨向於嚴重階段。
The phenomenon of pulverization is due to serious loss of light or loss of light after coating on epoxy floor paint. That is to say, not only the decorative properties of the coating have been completely lost, but also its protective properties have begun to be destroyed, which indicates that the aging of the coating has tended to a serious stage.
