Nantong Boda Biochemistry tells you what is wood preservative.

In a broad sense, wood preservatives can prevent wood from being exposed to decaying bacteria and harmful insects (such as termites). Chemicals that pose biological hazards. The use of wood preservatives can extend the service life of wood and avoid insect and ant bites.

Wood mold and decay are mainly caused by decay fungi, which require a mild climate and humid air to survive in wood or wood products.

1、Why use wood preservatives?

      1. The high moisture content of the logs leads to blue and moldy wood.

      2. The degreasing and drying of wood veneer does not meet the requirements, and there is too much moisture.

      3. Wooden products are soaked during transportation, and the storage warehouse is damp, with conditions for mold to survive.

2、What are the functions of wood preservatives in preserving wood?

      1. Reduce waste and losses caused by fungal mold during storage and transportation of wooden products.

      2. Reduce waste and losses caused by spoilage during processing and transportation.

      3. The wood is treated with pressurized wood preservative to make the wood have anti-corrosion function, which can extend the service life of the wood.

      4. Expand the use of wood.

3、Wood preservation treatment method

     Wood can be injected with preservatives in various ways, such as soaking, brushing, spraying, vacuum pressurization, etc. The requirements for drug loading and permeability of wood vary depending on its permeability.

4、Commonly used wood mold inhibitors

     The commonly used active ingredients of mold inhibitors in the current market are as follows:

       (1) Substituted aromatic hydrocarbons: such as pentachlorophenol, chlorothalonil, etc;

       (2) Quaternary ammonium salts; Such as dodecyl dimethyl benzyl ammonium chloride and organosilicon quaternary ammonium salt;

       (3) Triazole compounds; Such as fluconazole, cyproconazole;

       (4) Organic iodine compounds.

       (5) Isothiazolinone

       (6) Organic sulfur fungicide

     Due to the wide variety of molds and discoloring fungi, and some organic fungicides being only effective against certain fungi but unable to resist other fungal factors, most wood preservatives and discoloring agents on the market are mostly a combination of multiple anti-corrosion and antifungal agents.

     In recent years, with the enhancement of people's environmental protection concept and the improvement of living standards, antiseptic wood has been widely used in urban buildings, courtyard buildings, ancient building repair and other fields, and the demand for various wood preservatives in the market has an obvious upward trend.
