How can wood preservatives be optimized according to different wood species to improve the anti-corrosion effect?

The optimized design of wood preservatives is the key to ensuring the antiseptic effect. Different wood species require different preservative formulas and application methods due to their differences in structure and composition. In order to improve the antiseptic effect, wood preservatives must be adjusted according to the nature of the wood and the use environment to ensure their permeability, adhesion and protective properties for the wood. Generally speaking, wood can be divided into two categories: hardwood and softwood. The differences in fiber structure, moisture content and density of these two types of wood determine their different requirements in antiseptic treatment.
Hardwood is usually denser than softwood and has a more delicate texture. Due to its lower permeability, preservatives may encounter certain difficulties in penetration. Therefore, when treating hardwood for antiseptic treatment, the formula of preservatives is usually designed to have a stronger penetration. These preservatives often use smaller molecules or more affinity chemical components to help them better penetrate into the internal structure of the wood and provide deep protection. Preservatives for hardwood should also have good adhesion to ensure that the antiseptic layer after application is not easy to fall off or peel off, and effectively prevent the wood from being eroded by the external environment for a long time.
For cork, its structure is relatively loose, and there are more gaps between fibers, which makes it easier for preservatives to penetrate. Despite this, the preservative treatment of cork still requires delicate preparation. Cork preservatives usually do not need to have as strong penetration as hardwood, but focus on providing a more uniform protective layer and a longer service life. In addition, cork preservatives also need to take into account the characteristics of wood being easily affected by humid environments, so anti-mold and anti-fungal ingredients are often added to its preservative formula to deal with the problem of cork decay in humid or rainy environments.
In addition to the type of wood, the composition and application method of the preservative must also be optimized according to the use and environment of the wood. For example, if the wood is mainly used outdoors or exposed to harsh climates (such as high temperature, strong ultraviolet radiation, etc.), the preservative needs to have stronger weather resistance and anti-ultraviolet functions. At this time, the anti-ultraviolet component in the preservative is particularly important, which can effectively block the damage of ultraviolet rays to the wood and prevent the wood from fading, deforming or cracking under long-term exposure. In order to better adapt to the outdoor environment, the waterproof and moisture-resistant components in the preservative are also particularly important, which can prevent the wood from swelling, rotting or mildewing due to moisture absorption.
The treatment method of wood will also affect the realization of the anti-corrosion effect. For particularly thick or high-density wood, the application of preservatives may require multiple coatings or soaking to ensure that each layer can fully penetrate and form a uniform protective layer. In this case, the coating method of the preservative is also particularly critical. Using different methods such as brushing, spraying or soaking can effectively increase the contact area between the preservative and the wood and improve the anti-corrosion effect.
