The active ingredients in preservatives and antiseptic wood refer to the ingredients with real antiseptic effect. Therefore, preservatives and antiseptic wood must be marked with their active ingredients and content, and the supplier must attach the ex-factory inspection sheet. Taking CCA-C preservative as an example, the relative percentage of CuO, CrO3 and As2O5 and the total content of these three components in the product must be indicated.

相對的百分比說明改種防腐劑的綜合性能及抗流失性，總含量則說明售價應根據活性成分的含量而定，也就是說，30%活性成分含量的CCA防腐劑的售價只能是60%活性成分含量的一半。因為30%的CCA中70%是水，而60%的CCA中只含40%的水。用戶買來防腐劑和防腐木材后，還可以隨機取樣，委托有檢驗能力的單位進行檢測，以確定所購防腐劑和防腐木材的質量。

The relative percentage indicates the comprehensive performance and anti-loss property of the modified preservative, while the total content indicates that the selling price should be determined according to the content of the active ingredient, that is, the selling price of CCA preservative with 30% active ingredient content can only be half of that with 60% active ingredient content. Because 70% of CCA is water, while 60% of CCA contains only 40% water. After purchasing preservatives and antiseptic wood, users can also take random samples and entrust units with inspection capability to test to determine the quality of the preservatives and antiseptic wood purchased.

防腐劑和防腐木材的抗流失性的問題

The problem of erosion resistance of preservatives and antiseptic wood

對于在戶外使用的木材防腐劑和防腐木材，其抗流失性是決定其使用年限長短的重要因素。按照規定的方法、原料配比配制成的CCA、ACQ等水載防腐劑都具有良好的抗流失性能。但目前市場上也出現不按規定的要求生產的CCA和ACQ，結果抗流失性能很差，用這類防腐劑處理的防腐木材的使用年限當然就比較短。

For wood preservatives and antiseptic wood used outdoors, its anti-erosion property is an important factor determining its service life. CCA, ACQ and other water-borne preservatives prepared according to the specified method and raw material ratio have good anti-erosion performance. However, CCA and ACQ that are not produced according to the specified requirements also appear in the market at present, resulting in poor anti-erosion performance. The service life of the preservative wood treated with this kind of preservative is of course shorter.

防腐劑的抗流失性是在實驗室的條件下，將防腐木材浸泡在水中，不斷攪拌，每天更換一次水，一共要14天。測量水中防腐劑活性成分的含量而計算出來的。用戶可以做一些定性的試驗，如鋸一些買來的防腐木材，鋸成小塊，泡在水里，不斷攪拌，待一定時間后，如半天、一天，看一看水的顏色是不是變綠了，綠得厲害不厲害，即可以判斷防腐木材的抗流失性好還是不好?，F在市場上，甚至有AWPA標準明文規定不允許用CrO3、As2O5和CuSO4組合配制的CCA還在銷售。在市場銷售的ACQ防腐劑中，有的CuO的含量很低，不能起到標準的ACQ應有的防腐作用。所以用戶和客戶應該引起高度的重視。

The anti-erosion property of the preservative is to immerse the preservative wood in water under laboratory conditions, continuously stir it, and change the water once a day, a total of 14 days. It is calculated by measuring the content of active ingredients of preservatives in water. Users can do some qualitative tests, such as sawing some purchased antiseptic wood, sawing it into small pieces, soaking it in water, stirring it constantly, and after a certain period of time, such as half a day, one day, to see whether the color of the water has turned green, and whether the green is strong or not, that is, to judge whether the erosion resistance of the antiseptic wood is good or not. At present, there are even CCAs that are not allowed to be prepared with CrO3, As2O5 and CuSO4 in the market according to the AWPA standard. Among the ACQ preservatives sold on the market, some of them have very low content of CuO, which can not play the role of corrosion protection that the standard ACQ should have. So users and customers should pay high attention.
