    • A method for preserving wood by injecting into the wood a slurry having: particles of a sparingly soluble copper salt, copper hydroxide, or both, wherein the weight average diameter d50 of the particles in the slurry is between 0.1 microns and 0.7 microns and the d98 of the particles in the slurry is less than about 1 micron; a dispersant; and water. The dispersant is anionic or a mix of anionic and non-ionic. Advantageously, less than 20% by weight of the particles have a diameter less than 20 nanometers. Useful copper salts include basic copper carbonate, tri-basic copper sulfate, copper oxychloride, basic copper nitrate, basic copper borate, copper borate, basic copper phosphate, or copper silicate. The slurry most preferably includes copper hydroxide particles. The slurry further advantageously includes at least one organic biocide, wherein at least a portion of the organic biocide is coated on the particles.
    • 通过向木材注入具有:可溶性铜盐,氢氧化铜或两者的颗粒的浆料来保存木材的方法,其中浆料中的颗粒的重均粒径d <50>在 0.1微米和0.7微米,并且浆料中的颗粒的d 98小于约1微米; 分散剂; 和水。 分散剂是阴离子或阴离子和非离子的混合物。 有利地,小于20重量%的颗粒具有小于20纳米的直径。 有用的铜盐包括碱式碳酸铜,三碱式硫酸铜,氯氧化铜,碱式硝酸铜,碱式硼酸铜,硼酸铜,碱式磷酸铜或硅酸铜。 浆料最优选包括氢氧化铜颗粒。 浆料还有利地包括至少一种有机杀生物剂,其中至少一部分有机杀生物剂涂覆在颗粒上。

    • An injection device is disclosed for the treatment of wood without the necessity of a rivet-set. The injection device has a deformable elastic body having an internal cavity intended to receive a conical injection head and including an anti-return valve system therein. The upper part of the body has a double wall which consists of an external wall and an internal wall. The external wall absorbs deformations due to the driving-in phase of the injection device. The internal wall insures the nondeformation of the circular ridge of the cavity to guarantee the seal between the conical injection head and the injection device during the injection phase of the treatment product.
    • 公开了一种用于处理木材而不需要铆钉套装的注射装置。 注射装置具有可变形的弹性体,其具有用于容纳锥形注射头并且在其中包括止回阀系统的内部空腔。 身体的上部具有由外壁和内壁组成的双壁。 外壁吸收由于注射装置的驱入相的变形。 内壁确保腔的圆形脊的非变形,以确保在处理产品的注射阶段期间锥形注射头和注射装置之间的密封。
