    如何甄別市場上防腐木材的質量?

    來源:http://www.thecysterstory.com 時間:2020-08-19

    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。
    Preservative wood is still a relatively new product at present. It is a difficult problem for consumers who have just contacted how to identify their quality. Here is a method that can help customers make their own choices with simple methods.
    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 (no bran is better) intuitively, the finer the wood ring is, the better the material is generally. Because the tree ring density indicates that the wood grows slowly. In short, the wood with less bran in section should be better wood.
    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 to identify the quality of wood processing (uniform specifications, small error, good processing quality) can first be seen from the wood as a whole whether the specification is correct and neat, and there is no big error. Generally, the error of thinner plate should be less than 0.5-1 mm; the overall error of larger size material should not be greater than 2 mm. Generally, through the material under the production line, the specification is neat, and there is no error Large error will cause construction difficulty. In addition, for planing material, it is necessary to see the quality of surface planing. Smooth and natural is better.
    3. 甄別木材防腐劑穩定性的方
    3. How to identify the stability of wood preservatives
    (浸泡水的顏色變化最小的,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,顏色變化最小的,應該是防腐劑穩定性最好的.這不是一個絕對準確的方法,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。

    (the one with the smallest color change in the soaking water, the better the preservative stability) take the samples of different preservative wood (with the same specifications and the same moisture content) and immerse them in the water with the same temperature and volume. After the same soaking time, observe the color of the water. The one with the least color change should be the one with the best preservative stability, Because the preservative concentration may also vary greatly. After preservative treatment, because the stability of different preservatives varies greatly, after pressure treatment, the stability of wood is also greatly different. The use of preservatives with poor quality will not greatly improve the preservative performance of wood, on the contrary, it will cause great 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
    4. The method to identify the quality of wood preservative pressure treatment (sapwood fully immersed in preservative, clean and uniform surface is good) as far as Pinus densiflora is concerned, the quality of preservative completely immersed in sapwood is good, because the heartwood part of this tree species has natural durability. However, most other tree species should be soaked completely
