                                          如何甄別市場上防腐木材的質量

                                          來源:http://www.depatieguillot.com 時間:2021-06-25

                                          防腐木材目前還是個比較新的產品,對于剛剛接觸的消費者來說如何甄別他們的質量確實是個難題,這里給出一個方法可以幫助客戶用簡單的方法做出自己的選擇。
                                          At present, preservative wood is still a relatively new product. It's really a difficult problem for consumers who have just contacted how to identify their quality. Here's a method to help customers make their own choices in a simple way.
                                          甄別菠蘿格防腐木材質質量的簡單方法(不糠為好)從直觀上看,木材年輪越細密材質一般就越好,因為年輪細密說明木材生長緩慢,簡單說從切面看上去不那么糠的木材應該是較好的木材。
                                          A simple method to identify the quality of pineapple preservative wood (not bran is better) from the visual point of view, the finer the wood ring, the better the material is generally, because the wood growth is slow. In short, the wood with less bran should be better wood from the section.
                                          甄別木材加工質量的方法(規格統一,誤差小,加工質量好)可以首先從木材整體上看是否規格正確而且整齊沒有太大誤差一般較薄的板材誤差應小于0.5-1mm;較大規格的料的整體誤差也不應大于2mm.一般通過生產線下的料,規格整齊基本沒有誤差.而手工加工的料則有較大誤差,會造成施工難度。此外,對于刨光料,則還需看一下表面刨光的質量。平滑自然的為好。
                                          The method of discriminating wood processing quality (uniform specification, small error and good processing quality) can first see whether the specification of wood is correct and neat without too much error. Generally, the error of thinner wood should be less than 0.5-1 mm; The overall error of larger size material should not be greater than 2mm. Generally, the material under the production line is neat and has no error. However, the material processed by hand has large error, which will cause construction difficulty. In addition, for the planing material, you also need to look at the quality of the surface planing. Smooth and natural is better.
                                          3.甄別木材防腐劑穩定性的方法(浸泡水的顏色變化小的,防腐劑穩定性好)取不同防腐木材的樣塊(規格相同、含水率相同),分別浸泡在相同溫度,相同容積的清水中,經過相同的浸泡時間后,觀察水的顏色,顏色變化小的,應該是防腐劑穩定性好的。
                                          3. The method of screening the stability of wood preservatives (the color of soaking water changes little, the preservative stability is good) take different preservative wood samples (the same specifications, the same moisture content), respectively soak in the same temperature, the same volume of water, after the same soaking time, observe the color of water, the color change is small, the preservative stability should be good.
                                          這不是一個準確的方法,因為處理時的防腐劑濃度也可能差異較大.木材經過防腐處理以后,由于使用不同防腐劑本身的穩定性差別較大,加壓處理后,其在木材中的穩定性也有較大差別,使用質量不過關的防腐劑,對木材的防腐性能沒有太大改 善,相反會造成重大潛在的危害。
                                          This is not an accurate method, because the preservative concentration may vary greatly during the treatment. After preservative treatment, the stability of wood varies greatly due to the use of different preservatives. After pressure treatment, the stability of wood also varies greatly. The preservative with poor quality does not greatly improve the preservative performance of wood, On the contrary, it will cause significant potential harm.
                                          4.甄別木材防腐加壓處理質量的方法(邊材充分浸入防腐劑,表面干凈均勻為好)就歐洲赤松而言,從木材切面上看,防腐劑全部浸入邊材的質量為好,因為該樹種的心材部分具有天 然耐久性。但是其他多數樹種一般應全部浸入防腐劑。
                                          4. The method of screening the quality of wood preservative pressure treatment (sapwood is fully immersed in preservatives, the surface is clean and uniform is better) for Pinus densiflora, from the perspective of wood section, the quality of sapwood immersed with preservatives is better, because the heartwood part of the tree species has natural durability. However, most other tree species should be immersed in preservatives.
