What kind of liquid is the preservative made of?

      Since the preservative is also a sterilized insecticide, it has the same features as other used sterilization insecticides, such as pesticides, food preservatives, and hygienic insecticides; however, the preservative for wood preservatives is Wood, wood is bulky and dense, requires a long period of protection, and is used in a complex and harsh environment, so it differs from other uses of sterilized pesticides. In summary, wood preservatives should have the following characteristics.

      1. safety

Preservatives and wood treated therewith are poisoned by humans and animals, with minimal environmental pollution and the possibility of fire. Preservative safety is not only related to the preservative itself, but also to the rational use of science. In addition, preservative solutions should not cause corrosive effects on metal or plastic containers and equipment, as corrosion can cause leakage and environmental pollution. The handling, processing and other treatment of the treated preservative wood should also be safe. It should not emit toxic gases when burning, and it will not increase the risk of fire.

      2. Effectiveness

Preservatives must be effective in preventing wood-damaging organisms from infusing wood, and the effects can be measured by tests in the laboratory, in the field, and during use. However, the most effective wood preservatives must be deeply and evenly distributed in the wood to produce an effect, so the penetration of the preservative is very important. The penetration of the preservative has a very strong relationship with the formulation and quality of the preservative. The preservative must strictly control the quality of the treatment solution and the treated product.

      3. Persistence

Preservatives must remain in the wood for many years, as required. There are many factors that influence the persistence of preservatives, but two important factors are the physical and chemical properties of the preservative and the manner in which it remains in the wood. If the preservative chemically decomposes or volatilizes at room temperature, its preservative effect will not last. If the treated wood is used in a damp place, the active ingredients of the preservative must not be dissolved and lost by the rain. The anti-wear property of the preservative is derived from its own water-insoluble, such as coal creosote, oil-borne preservatives, etc., or after entering the wood, water-insoluble substances such as CCA and ACQ are formed in the wood. In addition, some wood preservatives are decomposed by some organisms and can also affect the persistence of preservatives.

      4. Economic

Price is an important factor that must not be forgotten. It is very important for producers of preservatives, owners of processing plants, and marketers and users of wood. If the raw material of a preservative is cheaper, the simpler and easier the preparation and manufacturing process, the lower the cost of the preservative and the more competitive it is on the market.
