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.

相对的百分比说明改种防腐剂的综合性能及抗流失性，总含量则说明售价应根据活性成分的含量而定，也就是说，30%活性成分含量的CCA防腐剂的售价只能是60%活性成分含量的一半。因为30%的CCA中70%是水，而60%的CCA中只含40%的水。用户买来防腐剂和防腐木材后，还可以随机取样，委托有检验能力的单位进行检测，以确定所购防腐剂和防腐木材的质量。

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.

防腐剂和防腐木材的抗流失性的问题

The problem of erosion resistance of preservatives and antiseptic wood

对于在户外使用的木材防腐剂和防腐木材，其抗流失性是决定其使用年限长短的重要因素。按照规定的方法、原料配比配制成的CCA、ACQ等水载防腐剂都具有良好的抗流失性能。但目前市场上也出现不按规定的要求生产的CCA和ACQ，结果抗流失性能很差，用这类防腐剂处理的防腐木材的使用年限当然就比较短。

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.

防腐剂的抗流失性是在实验室的条件下，将防腐木材浸泡在水中，不断搅拌，每天更换一次水，一共要14天。测量水中防腐剂活性成分的含量而计算出来的。用户可以做一些定性的试验，如锯一些买来的防腐木材，锯成小块，泡在水里，不断搅拌，待一定时间后，如半天、一天，看一看水的颜色是不是变绿了，绿得厉害不厉害，即可以判断防腐木材的抗流失性好还是不好。现在市场上，甚至有AWPA标准明文规定不允许用CrO3、As2O5和CuSO4组合配制的CCA还在销售。在市场销售的ACQ防腐剂中，有的CuO的含量很低，不能起到标准的ACQ应有的防腐作用。所以用户和客户应该引起高度的重视。

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.
