Disclosed is a method for preparing a hydrophilic writing sliced bamboo veneer, including, in sequence, the following steps: (1) processing a sliced bamboo veneer into thin bamboo sheets with a thickness of 0.2-0.6 mm; (2) selecting the thin bamboo sheets with less color difference and fewer processing defects, and rolling the selected thin bamboo sheets on a plane; (3) performing deburring, sanding, and surface polishing on the rolled thin bamboo sheets; (4) performing mildewproofing and mothproofing treatment on the thin bamboo sheets; (5) performing surface coating treatment on the thin bamboo sheets using a coating material; (6) drying the coated thin bamboo sheets at low temperature; (7) fine-polishing the dried thin bamboo sheets; (8) cutting the thin bamboo sheets; and (9) flattening, compacting, and piling the cut thin bamboo sheets for future use.

The present disclosure provides an environment-friendly mildew prevention method for bamboo. The mildew prevention method for bamboo includes the following steps: soaking the bamboo in an acid solution to obtain a reaction system; subjecting the reaction system to a hydrolysis reaction to obtain a hydrolyzed product; and washing and drying the hydrolyzed product in sequence to obtain mildew-proof bamboo, where the acid solution is an inorganic acid solution or an organic acid solution; the inorganic acid solution has a mass concentration of 0.5-8%; the organic acid solution has a mass concentration of 2-40%. The present disclosure uses an inorganic acid solution or an organic acid solution to treat the bamboo, and reduces the content of starch in the bamboo through a hydrolysis reaction, thereby reducing a carbon source with starch as the main nutrient on which a mildew fungus depends and achieving the purpose of preventing the bamboo from mildewing.

A device and a method for applying a liquid fire retardant onto hemp fibers and into hemp insulation batting using a multiple needle construction, which can act as an insulation substitute to be used in building structures that does not irritate the skin or contain harmful, toxic elements and is a quicker and a more efficient method with a reduction in drying time.

The present invention discloses an assembled bamboo sleeper, which is obtained by using a bamboo unit as a raw material, dried and modified at the temperature of 110-180° C., undergone coating treatment using a dopamine solution, adhesive dipping, curing and solidifying, assembling and gluing, further solidifying, further treatment using a dopamine solution, and anti-mildew and/or anti-corrosion and/or anti-insect treatment, and then fastened. The present invention further provides a preparation method for the foregoing bamboo sleeper. The bamboo sleeper prepared in the present invention is green and environmentally friendly, and applicable for ballasted tracks of railways and urban rail transit systems.

Disclosed is a bamboo strip shaping method, which includes the following steps: S01: cutting a bamboo tube, and removing inner joints, outer joints and bamboo outer skin; S02: trisecting or quartering the bamboo tube in a longitudinal direction to obtain curved bamboo strips; S03: placing the curved bamboo strips in a bamboo strip shaping device for processing; S04: subjecting the curved bamboo strips to steam treatment and heating softening treatment; S05: pressing and shaping the curved bamboo strips to obtain flattened bamboo strips, and drying for a first time under a maintained pressure; S06: wetting bamboo outer skin surfaces and bamboo inner skin surfaces of the flattened bamboo strips, and drying for a second time; and S07: wetting the bamboo outer skin surfaces and the bamboo inner skin surfaces of the flattened bamboo strips, and drying for a third time.

The present invention relates to a process for the treatment of vegetable barks, in particular of pineapple barks or melon barks, which allows to obtain a product of a completely vegetable nature, which also preserves the aesthetic appearance of the starting vegetable barks having, however, physical and mechanical characteristics greatly improved with respect to the first product, high stability and resistance so as to be able to use the material resulting from the treatment for the most varied applications, in the fashion sector, in particular for making and / or decorating garments and leather goods, in the furniture and design sector, and in any other related fields.
