What are the skills of anticorrosion wood in daily maintenance?
Anticorrosive wood is usually used in the balcony of the home, in the courtyard, in the garden. Because the characteristics of the anticorrosion wood is anticorrosion, the balcony, the courtyard are relatively moist places, this time to play the role of antiseptic wood. Although it is anticorrosion wood, but the basic maintenance work can not be forgotten. Get to know with the staff of the Beijing anti-corrosion wood manufacturer.
How to maintain the anticorrosion wood? What maintenance skills do you have?
In recent years, antiseptic wood products and related products are more and more popular among consumers. First, the antiseptic wood products have the characteristics of anti-corrosion, anti moth, waterproof and oil proof. Therefore, it is possible to withstand the harsh environment of the outdoors and not take care of it. Although there are so many advantages of antiseptic wood products, we can't do well in basic maintenance. Let's introduce the following knowledge in Bijie Xiaobian Xiaobian.
1. Anticorrosion treatment method of artificial anticorrosion wood
Artificial anticorrosive wood usually uses a water-soluble preservative, which is not suitable for dissolving. When it is pressed into wood in a closed vacuum tank, wood preservatives are inserted into wood fiber. After the pressure treatment of wood, more stable, preservatives can effectively prevent fungi, termites and insects on wood damage.
Two. Kinds of preservatives used for artificial anticorrosion wood
Antiseptic wood preservatives are related to their environmental protection, so it is necessary to understand. The main preservatives are CCA, ACQ and so on. CCA main component is copper Ge ACQ arsenic, main component of dissolved ammonia alkyl amine copper.
1, CCA anticorrosion wood
Early preservative wood uses CCA preservative. It is clean and odorless, and the treated wood surface can be painted. The high quality CCA agent has very stable characteristics. Because CCA contains extremely trace amounts of arsenic, it has certain toxicity. If it is only used outdoors, it is less harmful.
2, ACQ anticorrosion wood
ACQ 不含砷、铬等化学物质，对环境无不良影响，且不会对人畜鱼及植物造成危害。这种处理方法被认为可能成为CCA的有效替代品，但实验证明ACQ 不如 CCA稳定，比较易于流失，而且成本也高出CCA近20%。因此从市场看，这两种处理方法的防腐木材应该会共存一段时间。
ACQ does not contain chemicals such as arsenic and chromium. It has no adverse effects on the environment and does not cause harm to human and animal fish and plants. This method is considered to be an effective substitute for CCA. However, it has been proved that ACQ is not as stable as CCA, and it is relatively easy to drain, and the cost is also nearly 20% higher than that of CCA. Therefore, from the market, the two methods of antiseptic wood should be coexistence for a period of time.
Three. Construction and maintenance of anticorrosive wood
Anticorrosion wood, although anticorrosion, mildew proof, moistureproof, insect proof and so on performance outstanding, good durability. However, due to the special use of the environment, in the construction and maintenance of anticorrosion wood, if we pay attention to the correct method, it will greatly prolong its service life.
1. Pay attention to the expansion joint during installation
When installing antiseptic wood, there should be a gap of 0.2 to 1CM between the anticorrosive wood. The size of the gap is determined by the moisture content of the wood. When the wood moisture content is over 30%, it should not exceed 0.8CM. It can avoid the accumulation of rain water and the expansion of the antiseptic wood. In addition, an anticorrosion column with a thickness greater than 50mm or greater than 90mm can open a groove on the back to reduce the cracking.
2, choose the hardware connection that is not easy to rust
Bijie wood preservative Xiaobian that hardware application of stainless steel, galvanized or copper, mainly to avoid after rust, and effect of the connecting fastness. When the connection is installed, please drill in advance to avoid the cracking of the anticorrosion wood.
3. It is best to paint the protective coating after installation
Antiseptic and outdoor protective coatings should be applied to the damaged parts of the antiseptic wood. Because the wood preservative is half finished, the rough part after spreading wood moisture content dropped to below 20%, then sanding again, if you want to have a better effect, clean the surface after brushing or outdoor protective coatings;
4. Pay attention to the protection of finished products
After coating the antiseptic wood surface with outdoor protective coatings or oil based coatings, in order to achieve the best effect, avoid moving or heavy moving within 48 hours, so as not to damage the protective film formed by the anticorrosive wood surface. If you want to get better anti - dirty effect, it is necessary to do two special outdoor varnishes when necessary.
5. Regular cleaning of regular wax
The surface cleaning of antiseptic wood can be cleaned by general detergent. Tools can be used for brush. In later use, it needs regular intervals. The intervals between a year and a year and a half will be protected by wood wax oil, so as to enhance its surface waterproofing and antifouling performance.
