松木防蓝变和脱色处理技术的研究

Preventing and Removing of Blue Stain from Pine Timber

解决松木蓝变问题已成为松材加工高档用材的基础和提高松材商品附加值的关键。通过探索性试验和正交试验以及(?)差的分析比较,得到防蓝变的优配方为:0.75％A1+0.50％A3+0.10％B。此配方在试验所观察的10周内防治效力达到了100％。同时,对松木蓝变色斑的脱除研究表明,在浓度5％的C药剂中加入D药剂,调节其溶液的pH值为10左右,加热到50-60℃对板材进行处理可有效脱除蓝变色斑。

In order to produce high quality pine timber and increase its additional value,it is a key link to solve the problem of pine timber blue stain. In experiments,different chemicals and their combinations were used for preventing and removing of blue stain from pine timber. Based on exploration and orthogonal experiment results,the best recipe for anti-stain treatment was:0.75% A1 +0.50%A3 + 0.10%B,and its preventing efficiency reached to 100% during experiment period of 10 weeks. The result of blue stain removing experiment showed:after attacked timber socked into 5%C solution with temperature being 50- 60℃ and pH being about 10 for 3-5 minutes, the blue stain could be removed completely.
