    防腐木的變色該如何進行處理?

    來源:http://www.thecysterstory.com 時間:2020-08-25

    防腐木是一種在現在社會中被人們廣泛用來制作花架和花盆的產品,具有不錯的防腐效果,得到了人們的喜愛,同時該產品在使用的過程中容易出現變色的現象,那么您知道如何進行處理嗎?就先讓濟南防腐木小編帶您來簡單看一下:
    Antiseptic wood is a kind of product which is widely used to make flower racks and flowerpots in modern society. It has good antiseptic effect and is loved by people. At the same time, it is easy to change color in the process of using. Do you know how to deal with it? Let's have a brief look at Jinan antiseptic wood weaving tape
    出現木材變色的原因有多種,簡單的來說主要是內部和外部兩個因素.先要說的就是外部因素:當木材受到外界一些環境的影響之后導致其表面的一些紋理疏松,摸起來比較粗糙,甚至是失去了表面的一些粘附性纖維出現裂紋或脆性碎片等,這些會導致其進行褪色.
    There are many reasons for wood discoloration, which are mainly internal and external factors. The first thing to say is external factors: when the wood is affected by some external environment, the texture on the surface is loose, the texture is rough, and even some adhesive fibers on the surface are lost. Cracks or brittle fragments appear on the surface, which will lead to discoloration
    引起木材變色的木材內部要素是指:木材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只包括羰基羧基不飽和雙鍵及共軛系統等發色基團而且包括羥基等助色基團。

    The internal factors that cause wood discoloration are: the wood is composed of cellulose, hemicellulose, lignin and a small amount of extract, which not only includes the chromogenic groups such as carbonyl carboxyl unsaturated double bond and conjugated system, but also includes color supporting groups such as hydroxyl group.
    光變色:是木材中某些物質挑選吸收了波長大于290nm的光,發作能級之間電子的變遷,然后構成光變色的化學鍵,導致木材色彩的改動。光變色的避免:間隔紫外光UV;改動材內吸光成分的結構損壞參加變色的物質結構,因此阻隔氧和捕集原子氧,捕集自由基抽提溶劑
    Photochromism: some substances in wood absorb light with wavelength greater than 290 nm, and then form chemical bonds of photochromism, resulting in the change of wood color. The avoidance of photochromism: interval ultraviolet and UV; change the structure of light absorption components in wood, damage the structure of materials involved in discoloration, so as to block oxygen and trap atomic oxygen, and capture free radical extraction solvent
    光變色的消除:要消除光變色使木材材面康復原有的正常材色,可采用下列兩種辦法:用過氧化氫或亞氯酸鈉等氧化型漂白劑處理木材,分化損壞材面的發色結構系統。用砂紙砂光或刨削辦法除去。關于褪色材面可用相應的染料或顏料涂覆。
    Elimination of photochromism: in order to eliminate the photochromism and recover the original normal wood color, the following two methods can be used: to treat the wood with peroxide or sodium chlorite and other oxidizing bleaching agents to differentiate and damage the hair color structure system of the wood surface. Remove by sanding or planing with sandpaper. The surface of discolored wood can be coated with corresponding dyes or pigments.
