| abstract | 462,597. Preserving wood. RAYNER, G. F. (Osmose Holzimpraegnierung Ges.) Sept. 9, 1935, No. 25065. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 30, 1936.] Drawings to Specification. [Class 140] Freshly-cut timber is preserved by removing the bark, coating the surface with an aqueous paste containing a water-soluble preservative, and covering the coated wood with a windproof and waterproof covering to retard drying until the preservative has diffused into the wood to the desired depth. The covering may be of any suitable material, e.g. sheet iron, paper, fabric, straw, &c., the wood being closely stacked before covering. Suitable preservative agents are water-soluble inorganic substances, e.g. potassium fluoride or zinc chloride together with fungicides, e.g. copper sulphate, potassium sulphide, mercuric chloride, zinc fluorsilicate, and insecticides, e.g. potassium arsenite or potassium arsenate. Two or more soluble inorganic substances, capable of reacting within the wood to form an insoluble product, may be employed, e.g. a fluoride or arsenate with a dichromate. The preservative substance is formed into a paste with starch, casein, glue, gelatine, agar agar, or gum arabic. A waterinsoluble, organic protective agent, e.g. dinitrophenol, dinitrocresol, tar oils or liquid petroleum may be applied to the wood after application of the preservative and before or after the wood has become air dry, or it may be incorporated in the paste. Examples are given of pastes including dinitrophenol. Specification 381,030 is referred to. |
