Problems solved by technology

[0004] The existing commonly used softening treatment process for bamboo is to soak the bamboo veneer in 40-50°C water for 6-10 hours and then slowly heat up. 70°C is enough. In order to soften the bamboo quickly, 10% sodium bicarbonate is often added during cooking to shorten the cooking time, but softening the bamboo veneer with sodium bicarbonate will destroy some component structures of the bamboo veneer and reduce the bamboo veneer. quality

Embodiment 1

[0018] The invention discloses a method for softening bamboo veneers. The method for softening bamboo veneers is to preheat the bamboo veneers, then use the preparation liquid of shiitake mushrooms mixed with water for cooking, and carry out auxiliary treatment with ultrasonic waves.

[0019] The preparation method of the Lentinus edodes preparation liquid is as follows: After mixing the leaves and stems of the Lentinus edodes, crush them to 100 mesh, add 10 times the mass of water to decoct for 32 minutes, then stir at 2000r / min for 10 minutes, then cool to 30°C, Obtain a decoction, then add a compound enzyme of 0.8% of the decoction mass to the decoction, enzymatically hydrolyze for 4 hours, then perform an enzyme inactivation treatment, then cool naturally to room temperature, and then carry out solid-liquid decoction under high-speed centrifugation. Separation to obtain a mixed solution, which is the preparation solution of Lentinus edodes.

Abstract

The invention discloses a bamboo single-plate softening method. The bamboo single-plate softening method comprises the steps that after a bamboo single plate is preheated, hydrocotyle vulgaris preparation liquid is adopted for being mixed with water to conduct stewing, and auxiliary treatment is conducted through ultrasonic waves. According to the bamboo single-plate softening method, the hydrocotyle vulgaris preparation liquid is adopted for being mixed with the water to conduct stewing treatment on the bamboo single plate, active ingredients in the hydrocotyle vulgaris preparation liquid can greatly increase the wood softening speed, and particularly after ultrasonic auxiliary treatment, the bamboo softening speed can be further increased; meanwhile, by adoption of the effect of the hydrocotyle vulgaris preparation liquid, the softening process of the bamboo single plate can be mild, and no damaging effect is exerted on an organization structure of the bamboo single plate; and through treatment of the bamboo single-plate softening method, water molecules can more easily enter the amorphous region of the organization of the bamboo single plate to enable fibers to be expanded, so that the elastic modulus of the bamboo single plate is remarkably decreased, the water content of the bamboo single plate is increased, and the plastic property of the bamboo single plate is improved.

Description

technical field [0001] The invention belongs to the technical field of bamboo softening treatment, in particular to a method for softening bamboo veneers. Background technique [0002] Bamboo, also known as bamboo, is a branch of Poaceae, distributed in subtropical regions, also known as bamboo or bamboo. Some are as low as grass, and some are as tall as trees. Usually grown in sheets by underground creeping rhizomes. Also can be by the procreation of blossoming and having seeds, its seed is called as bamboo rice. For perennials. There are some types of bamboo shoots that are edible. Tall, fast-growing grasses with woody stems. [0003] Bamboo is not only smooth and beautiful in appearance, but also has good strength and flexibility, and has good application space in many fields. Now in order to improve the economic value of bamboo. [0004] The existing commonly used softening treatment process for bamboo is to soak the bamboo veneer in 40-50°C water for 6-10 hours an...
