Preservative wood is a kind of wood which has been treated properly. It not only has good preservative effect, but also can prevent the invasion of borers and termites. For the wide use of the product, many people are concerned about the anti-corrosion effect of the product and how long the anti-corrosion time is. So let's give you a brief introduction of Jinan antiseptic wood.
The service life of preservative wood depends on the retention and penetration of preservative in wood. This mainly depends on the absorption capacity of wood. Therefore, the moisture content of wood before preservative treatment is less than or equal to 13%.
Now the medicine for making antiseptic wood is good and bad, and the manufacturing process is shoddy. For example, it is required to be dried before anti-corrosion treatment, but in the market, air drying is used as drying. As a result, the outside is dry and the inside is still wet. In this way, the liquid medicine can not be soaked, and the antiseptic wood is easy to crack and rot.
The preservative wood sold on the market is basically made of three kinds of wood: Pinus sylvestris var. mongolica, Eucalyptus salicina and pineapple. Among them, Pinus sylvestris var. mongolica is more expensive, and Eucalyptus salicina is more expensive. The most expensive is pineapple, which is imported from Brazil. Because of the high density of wood, raw materials alone cost 20000 yuan / m3, which is even more expensive after processing. So in conclusion, the effect of anti-corrosion wood is good, and the anti-corrosion aging time of anti-corrosion wood is relatively long.
Preservative wood is a kind of common wood which has the characteristics of anti-corrosion, moisture-proof, anti fungus, anti insect, anti mildew and water-proof. There are two common preservative materials in China: Pinus sylvestris var. mongolica and Pinus sylvestris var. mongolica. It can directly contact with soil and humid environment, and is often used in outdoor floor, engineering, landscape, antiseptic wood flower rack, etc. for people to rest and enjoy natural beauty.
