    • Preservative composition for lignocellulosic-based composites providing rapid and long-lasting protection against insect and fungal attack, in both low and high moisture environments, through the use of a combination of higher solubility and lower solubility borates. Pesticidal amounts of a lower solubility borate and a higher solubility borate are combined before or during their incorporation into a lignocellulosic-based composite. Useful low solubility borates include copper borate, zinc borate and barium metaborate. Useful high solubility borates include boric acid, boric oxide, ammonium borate and alkali metal borates such as sodium borate. Some alkaline earth metal borates, including calcium borates, calcium magnesium borates, magnesium borates and calcium sodium borates, are of intermediate solubility and may be used effectively as either a low soluble or high soluble borate depending on the combination used.
    • 木质纤维素基复合材料的防腐组合物通过使用更高溶解度和较低溶解度的硼酸盐的组合,在低和高湿度环境中提供快速和持久的保护,防止昆虫和真菌侵袭。 较低溶解性硼酸盐和较高溶解性硼酸盐的杀虫剂量在其掺入木质纤维素基复合材料之前或期间合并。 有用的低溶解度硼酸盐包括硼酸铜,硼酸锌和偏硼酸钡。 有用的高溶解性硼酸盐包括硼酸,氧化硼,硼酸铵和碱金属硼酸盐如硼酸钠。 一些碱土金属硼酸盐,包括硼酸钙,硼酸钙镁,硼酸镁和硼酸钙钠,具有中等溶解度,可根据使用的组合有效地用作低溶解度或高溶解性硼酸盐。
