                                          防腐木花架的常壓處理方法有哪些?

                                          1、對干燥木材的處理方法。
                                          1. Treatment of dry wood.
                                          ①常規處理,主要包括了噴淋、噴霧、涂刷以及浸漬這幾種方法。和其他的方法相比,這些方法中,防腐劑的保持量以及滲入深度都不會很大。適合使用在較為容易滲透的木材上,即使這樣效果也不會很好。
                                          (1) conventional treatment mainly includes spray, spray, brushing and impregnation. Compared with other methods, the preservative retention and penetration depth of these methods are not very large. It is suitable for use on wood which is easy to penetrate, even if the effect is not very good.
                                          ②熱冷槽處理。在常壓下這種方法的效果好,采用的是熱脹冷縮產生的壓力差。
                                          ② Hot and cold bath treatment. Under normal pressure, the effect of this method is good, using the pressure difference caused by thermal expansion and cold contraction.
                                          2、對潮濕木材的處理方法。
                                          2. Treatment of wet wood.
                                          ①擴散法。這種方法是利用的分子擴散規律,主要是利用的木材之中的水分。水載防腐劑會從高濃度向低濃度進行擴散,讓防腐劑成分能夠被輸送到木材之中。
                                          ① Diffusion method. This method is to use the law of molecular diffusion, mainly the use of moisture in the wood. Water borne preservatives will diffuse from high concentration to low concentration, so that preservative components can be transported to wood.
                                          這種方法有幾個必須的條件:
                                          There are several necessary conditions for this method
                                          (1)木材中水分含量必須要高;
                                          (1) The moisture content of wood must be high;
                                          (2)防腐劑在水中的溶解度要高;
                                          (2) The solubility of preservative in water is higher;
                                          (3)防腐劑在木材之中的固著速度較慢;
                                          (3) The fixation speed of preservative in wood is slow;
                                          (4)環境溫度較高。
                                          (4) The ambient temperature is high.
                                          ②輸液置換。這種方法適用范圍較窄,只適用于剛剛采伐下來的原木或者是活立木。同時,還要求防腐劑的水溶性好。
                                          ② Transfusion replacement. This method has a narrow scope of application and is only suitable for logs or standing trees that have just been cut. At the same time, the water solubility of preservatives should be good.
                                          總之,對于園林用木材的防腐處理防腐有很多,不僅僅使用防腐劑來進行處理,還可以通過其他多種方法來進行處理。對于園林用木材防腐處理的工藝研究可以更好地為園林建設提供支持。
                                          In short, there are a lot of preservative treatment for garden wood, not only using preservatives to deal with, but also through a variety of other methods to deal with. The research on the technology of preservative treatment of landscape wood can provide better support for landscape construction.
