From small balconies to large outdoor garages, galleries, and platforms, wood preservatives are basically used. However, does the wood that we purchase have really been used for thirty years as we imagine it? What is good quality antiseptic wood? The editors visited the building materials market, and also contacted the people in the industry to conduct a survey on the wood that we use.
Material rich anti-corrosion wood
As the number of people who own villas increases, so does the use of wood. Anticorrosive wood is solid wood in the first place, and because it is solid wood, it will be cracked, corroded, and deformed. In contrast, wood is passed through a closed pressure-resistant anticorrosive tank, and the anticorrosive agent is pressed into the wood with vacuum pressure. Exquisite, manufactured wood usually has a 30-year lifespan.
The most popular wood preservation - southern pine
The Southern Pine of the United States is regarded as the "king of the world's cork". Its ability to accept high-pressure injections of preservatives is high. Its high permeability allows Southern Pine to be free from the hazards of moisture, decay, termites and marine life. The ability to preserve corrosion can be maintained at 50. In years, it is only easy to deform, so it needs proper clearance when laying.
The most environmentally friendly wood - red cedar
Produced in the western United States and Canada, Red Cedar is a high-grade, naturally preserved wood. Its naturally-occurring acidity ensures that wood is not attacked by insects, and it is highly stable and not easily deformed. Because there is no erosion of medicine, it will not cause pollution to the environment. It can be used not only outdoors, but also indoor and outdoor walls such as kitchen and bathroom can be used as laying. The useful life is about 30 years.
The most affordable wood preservative - Pinus sylvestris
Scotch pine produced in China is treated to prevent mold, termites, and microorganisms from invading, and it can effectively suppress changes in the moisture content of treated wood, reduce the degree of cracking of wood, and extend the life of wood to 40 to 50 years. Southern pine is more stable. And Pinus sylvestris preservative wood is processed domestically, so the price will be relatively affordable.
The secret of the wood preservative business
Milk Riga hydrogen ammonia, Sudan red in hamburgers, sweeteners in Riga juice are all common secrets in the industry. Preservative wood is the most important wood in outdoor building materials. When buying, it also needs attention. Do not be fooled by these businesses.
Secret 1: Imported Southern Pine
Anti-corrosion wood is divided into imported logs, imported processing; imported logs, domestic processing; domestically produced logs, domestic processing of these three, under normal circumstances, 2800 yuan / cubic meter of wood preservatives are mostly homemade domestic processing.
Secret 2: antiseptic preparation
The processing of preservative wood is achieved through the preparation and the sealing of high pressure to prevent corrosion, but in order to steal the process, many manufacturers will add arsenic (the main component of arsenic) in the preparation, which can be used after simple immersion, but the arsenic powder It will float in the air and be poisoned easily.
Secret III: Anti-corruption period
The poor quality of wood can only last for a period of 7 years, and cracks and deformation usually occur after one year. Many businesses use a layer of varnish on the surface during production to prevent ganging, so that a layer of paint is applied every other year to extend the period of antisepsis for three to five years.
Secret IV: Fir replacement
Not all green wood is wood. The fir has been soaked with simple preservatives and then applied with anti-corrosion paint. It also has a service life of about 7 years. In addition to the porches, wooden huts, and garages, the wooden platform and outdoor furniture can be replaced with fir, which is less than half the price of wood.
Secret 5: Mahogany
There is a high-end preservative wood in the market now, and the price has reached 17,000/m3. In fact, Porrog was originally used as an alternative to mahogany furniture, and its price is about 7,000 yuan/m3 or even cheaper. The material is relatively stable, and its anti-corrosion effect is not very prominent. It can not be called professional wood.
Outdoor building materials, in addition to preservative wood like plastic wood, wrought iron, PVC material, and resin are all good substitutes. Everyone should not look at prices completely when picking up wood, but also have to look at the company's certificates, pharmaceutical instructions, etc., so that they will not spend money to buy good things.
