Embodiment 1

[0021] First activate Gluconacetobacter xylinum, then inoculate the seed liquid into the culture medium according to the volume ratio of 2% inoculum, and put it into a constant temperature incubator at 30°C for static culture for 6 days. Then take out the bacterial cellulose film that generates, put into NaOH solution and soak for treatment, then rinse with flowing distilled water until the pH of the washing solution is close to neutral; put the bacterial cellulose film obtained above into a beater, and grind it at 10000rpm for 10 Minutes; the above-mentioned gained pasty bacterial cellulose is sterilized. Pour the sterilized paste bacterial cellulose into the eyebrow pencil casing mold, dry, cool, and air-dry to form; pour the medicine into one eyebrow pencil casing, and put the other eyebrow pencil casing on the eyebrow pencil filled with medicine At the mouth of the shell, it is used to close the eyebrow pencil.

Embodiment 2

[0023] First activate Gluconacetobacter xylinum, then inoculate the seed liquid into the culture medium according to the volume ratio of 3% inoculum, and put it into a constant temperature incubator at 30°C for static culture for 7 days. Then take out the bacterial cellulose film that generates, put into NaOH solution and soak for treatment, then rinse with flowing distilled water until the pH of the washing solution is close to neutral; put the bacterial cellulose film obtained above into a beater, and grind it at 12000rpm for 7 Minutes; the above-mentioned gained pasty bacterial cellulose is sterilized. Pour the sterilized paste bacterial cellulose into the eyebrow pencil casing mold, dry, cool, and air-dry to form; pour the medicine into one eyebrow pencil casing, and put the other eyebrow pencil casing on the eyebrow pencil filled with medicine At the mouth of the shell, it is used to close the eyebrow pencil.

Embodiment 3

[0025] First activate Gluconacetobacter xylinum, then inoculate the seed liquid into the culture medium according to the volume ratio of 4% inoculum, put it into a constant temperature incubator at 30° C. and cultivate it statically for 6 days. Then take out the bacterial cellulose film that generates, put into NaOH solution and soak for treatment, then rinse with flowing distilled water until the pH of the rinse solution is close to neutral; put the bacterial cellulose film obtained above into a beater, and polish it at 8000rpm for 15 Minutes; the above-mentioned gained pasty bacterial cellulose is sterilized. Pour the sterilized paste bacterial cellulose into the eyebrow pencil casing mold, dry, cool, and air-dry to form; pour the medicine into one eyebrow pencil casing, and put the other eyebrow pencil casing on the eyebrow pencil filled with medicine At the mouth of the shell, it is used to close the eyebrow pencil.

Abstract

The invention discloses a preparation method for a bacterial cellulose eyebrow pencil shell and belongs to the field of chemical industry. The preparation method comprises the following steps of (1) production of bacterial cellulose: firstly, activating gluconacetobacter xylinus, then inoculating a seed solution of the activated gluconacetobacter xylinus to a culture medium according to an inoculation amount with a certain volume ratio, putting the culture system in a constant-temperature incubator for standing culture, then taking out produced bacterial cellulose, putting the bacterial cellulose in a NaOH solution for soaking treatment, and washing the bacterial cellulose with flowing distilled water until a pH value of a washing liquid is close to be neutral; and (2) production of the bacterial cellulose eyebrow pencil shell: putting the pure bacterial cellulose in a pulping machine, beating the pure bacterial cellulose into a paste, and then pouring the paste into an eyebrow pencilshell die for air drying molding. The bacterial cellulose eyebrow pencil shell prepared by the preparation method disclosed by the invention is free of toxic and side effects; even if being used for along time, the bacterial cellulose eyebrow pencil shell cannot generate adverse effects to a human body; and in addition, the bacterial cellulose eyebrow pencil shell is simple and reasonable in process and low in cost, is safe and reliable, is suitable for mass production of related enterprises and has a relatively good market prospect.

Description

technical field [0001] The invention relates to a preparation process of an eyebrow pencil shell based on bacterial cellulose material, which belongs to the field of chemical industry. Background technique [0002] Bacterial cellulose refers to the general term for cellulose synthesized by certain microorganisms in the genus Acetobacter, Agrobacterium, and Rhizobium under different conditions. Compared with plant cellulose and synthetic bacterial cellulose, it has many unique properties. [0003] ① Compared with plant cellulose, bacterial cellulose has no associated products such as lignin, pectin and hemicellulose, and has high crystallinity and high degree of polymerization; [0004] ②Ultrafine mesh structure. Bacterial cellulose fibers are composed of microfibers with a diameter of 3 to 4 nanometers to form fiber bundles with a thickness of 40 to 60 nanometers, which are interwoven to form a developed ultrafine network structure; [0005] ③ The elastic modulus of bacte...
