防腐木涼亭花架現在在很多地方都可以見到，大到公園廣場小到小區花園，隨處可見他的身影，但是隨著時間的邊長，防腐木涼亭花架可能會出現變色開裂等現象，在網站之前的文章中我們了解到了開裂的處理方法，那今天山東亭子小編就來給大家介紹一下防腐木涼亭花架變色的處理方法及原因：
The anti-corrosion wooden arbor flower stand can be seen in many places, ranging from park square to community garden. However, with the time going on, the anti-corrosion wooden arbor flower stand may change color and crack. In the previous article of the website, we learned how to deal with the cracks. Today, Shandong Pavilion small editor will introduce the anti-corrosion wood to you Treatment methods and reasons for color change of arbor frame:
首先來說一下引起防腐木涼亭花架變色的原因：
First of all, let's talk about the reasons for the discoloration of the flower stand in the antiseptic wood Pavilion:
1.內部因素：防腐木涼亭花架的木材主要由纖維素半纖維素木質素及少量的提取物組成的復雜天然高分子化合物不僅包含羰基羧基不飽和雙鍵及共軛體系等發色基團而且包含羥基等助色基團。
1. Internal factors: the complex natural macromolecule compound composed of cellulose hemicellulose lignin and a small amount of extract mainly contains not only the chromogenic groups such as carbonyl carboxyl unsaturated double bond and conjugate system, but also the chromogenic groups such as hydroxyl group.
2.外部因素：防腐木涼亭花架的木材易受外界環境的作用而使木材表面紋理疏松、粗糙不平、變色和褪色，甚至木材失去表面粘附性纖維脫離產生裂紋或脆性碎片逐漸脫落。
2. External factors: the wood of the anti-corrosion wood arbor is easy to be affected by the external environment, which makes the surface texture of the wood loose, rough, discolored and faded, and even the surface adhesive fiber of the wood is lost, resulting in cracks or brittle fragments falling off gradually.
接下來防止防腐木涼亭花架變色及處理的方法：
The next step is to prevent the color change of the anti-corrosion wooden arbor and the treatment methods:
防腐木涼亭花架變色就是木材中某些物質選擇吸收了波長大于290nm的光，發生能級之間電子的變遷，從而形成光變色的化學鍵，導致木材顏色的改變。
The discoloration of the flower stand in the anti-corrosion wood Pavilion is that some substances in the wood choose to absorb the light with the wavelength greater than 290nm, and the electron changes between the energy levels, thus forming the chemical bond of the photochromism, leading to the change of the wood color.
預防措施：隔斷紫外光UV;改變材內吸光成分的結構破壞參與變色的物質結構，因此隔絕氧和捕集原子氧，捕集自由基抽提溶劑
Preventive measures: block UV light; change the structure of the light absorbing component in the material to destroy the structure of the substance involved in color change, so isolate oxygen and trap atomic oxygen, and trap free radical extraction solvent
處理方法：1.用砂紙砂光或刨削方法除去。對于褪色材面可用相應的染料或顏料涂覆。
Treatment: 1. Remove by sanding or planing with sandpaper. For the discolored material surface, the corresponding dye or pigment can be applied.
2.用過氧化氫或亞氯酸鈉等氧化型漂白劑處理木材，分解破壞材面的發色結構體系。
2. Hydrogen peroxide or sodium chlorite were used to treat the wood and decompose the chromogenic structure system.
以上就是今天
山東亭子小編給大家帶來的關于防腐木涼亭花架的變色的原因及預防和處理的相關知識的介紹，大家在進行處理的時候一定要注意采用正確的方法，保證防腐木涼亭花架的使用效果。
The above is the introduction of the cause of discoloration of the anti-corrosion wooden arbor flower stand and the related knowledge of prevention and treatment brought to you by the small edition of Shandong Pavilion today. You must pay attention to the correct methods to ensure the use effect of the anti-corrosion wooden arbor flower stand when processing.
