Embodiment 1
[0028] Embodiment 1: the manufacture method of the composite preservative wood of the strong laminated structure of decoration, its production step comprises:
[0029] (1) The fast-growing wood is processed into a small veneer with a thickness of 1-30mm by rotary cutting or planing, and then dried at 30-60°C to make the moisture content below 16%. The purpose of this treatment is to absorb the agent quickly and more when impregnated with preservatives, and the other is to prevent the wood from becoming moldy and deteriorating during storage;
[0030] (2) Since small veneers need to be impregnated, in order to reduce production costs, no pressure or vacuum is required, and the small veneers treated in step (1) are impregnated with preservatives, preservatives and Water mixing, the mixing ratio is 1:14~20, the mixture of preservative and water absorbed per 100kg small veneer is 30~60kg, the immersion time is controlled within 10~30 minutes, and then the low temperature i...
Embodiment 2
[0034] Embodiment 2: the manufacturing method of the composite preservative wood of the recombined wooden structure with strong decorative property, its production step comprises:
[0035] (1) The fast-growing wood is processed into small wood with a filamentous structure of 1~30mm thickness by rolling and crushing, and then dried at 30~60°C to make the moisture content below 16%. The first purpose is to absorb the agent quickly and more when impregnated with preservatives, and the second is to prevent mildew and deterioration of small wood units during storage;
[0036] (2) Since the small filamentous wood needs to be impregnated, in order to reduce the production cost, it is not necessary to pressurize or vacuumize. The small filamentous wood treated in step (1) is impregnated with preservatives by impregnating at normal temperature and pressure to prevent corrosion. Preservatives and water are mixed, the mixing ratio is 1:14~20, the mixture of preservatives and wa...
