Problems solved by technology

[0002] In daily life, people often use bamboo to make chopsticks. Although the cost is low, bamboo chopsticks are susceptible to mildew and deterioration due to the high sugar and moisture content in bamboo, and are often eaten by some pests.
After the bamboo chopsticks are eaten by moths, there will be uneven spots and moths in mild cases. Although they can be used, they are not beautiful and the service life is not long. In severe cases, moth holes will be formed, and the bamboo moths will be broken and cannot be used any more.
There are many a

Embodiment 1

[0014] Embodiment 1, in the growth direction of bamboo, according to fixed certain interval horizontal sawing, each section of bamboo is split into four pieces, color separation and disinfection carbonization, bamboo chip finished product is sent into drying disinfection carbon dryer, drying disinfection carbon The temperature of drying machine heating is 160 ℃, and the heating time is 2 hours, and the bamboo chips are carbonized, and the degree of carbonization is 5%, and they are taken out. Grinding and smoothing the joints of the obtained carbonized bamboo slices. Utilize the chopsticks molding machine (existing) to process and shape, and the surface pattern can be carved by hand.

Embodiment 2

[0015] Embodiment 2, in the growth direction of the bamboo material, cut it horizontally at certain intervals, split each section of the bamboo material into four large pieces, color separation and sterilized carbonization, send the bamboo chip finished product into the drying and sterilizing carbon dryer, and the drying and sterilizing carbon dryer The heating temperature is 170° C., the heating time is 3 hours, the bamboo chips are carbonized, and the degree of carbonization is 20%, and they are taken out. Grinding and smoothing the joints of the obtained carbonized bamboo slices. Use the chopsticks molding machine to process and shape, and hand-carve the surface pattern.

Embodiment 3

[0016] Embodiment 3, in the growth direction of bamboo timber, cut horizontally at certain intervals, each section of bamboo timber is split into four large pieces, color separation and carbonization are sterilized, and the bamboo chip finished product is sent into the drying and disinfection carbon dryer, and the drying and disinfection carbon dryer The heating temperature is 190° C., the heating time is 4 hours, the bamboo chips are carbonized, and the degree of carbonization is 30%, and they are taken out. Grinding and smoothing the joints of the obtained carbonized bamboo slices. Use the chopsticks molding machine to process and shape, and hand-carve the surface pattern.

[0017] Under this final carbonization temperature condition, the elastic modulus of the carbonized bamboo slices increases, and the change range of static bending strength and impact toughness is small, which meets the strength requirements for making carbonized bamboo chopsticks. The shrinkage is small...

Abstract

The invention discloses a preparation method of carbonized bamboo chopsticks. The preparation method comprises the following process steps that 1, a bamboo is preprocessed, wherein the bamboo is transversely sawed off in the length direction of the bamboo at intervals, and each sawed-off section of the bamboo is split into four pieces; 2, color separation and sterilization carbonization are carried out, wherein the bamboo stick products are sent to a drying and disinfecting carbonizing drying machine, the heating temperature of the drying and disinfecting carbon drying machine is 160-190 DEG C, the heating time is 2-4 hours, the bamboo sticks are carbonized, the carbonization degree of the toothpick is 5%-30%, and the toothpick is taken out; and 3, the carbonized bamboo chopsticks are prepared, wherein the obtained carbonized bamboo pieces are ground, so that flat plates are manufactured, and a chopstick forming machine is used for machining and forming.

Description

technical field [0001] The invention relates to a method for preparing carbonized bamboo chopsticks by utilizing shallow and uniform carbonized bamboo slices. The invention belongs to the technical field of bamboo chopsticks preparation. Background technique [0002] In daily life, people often use bamboo to make chopsticks. Although the cost is low, bamboo chopsticks are susceptible to mildew and deterioration due to the high sugar and water content in bamboo, and are often eaten by some pests. After bamboo chopsticks are eaten by moths, there will be uneven patterns and moths in mild cases. Although they can be used, they are not beautiful and the service life is not long. There are many anti-moth methods, such as high-temperature treatment, paint treatment, chemical treatment, etc. Although these treatment methods can achieve the purpose of anti-moth, but these methods have their own disadvantages. The glucose group in the cellulose macromolecule contained in it will un...
