Problems solved by technology

[0004] Traditional sandalwood pulping adopts alkaline method, but due to the high content of pigments and polysaccharides (such as glue, plant mucus, starch, pectin, polylactose) in sandalwood bark, it will increase the concentration of drugs during alkaline pulping. consume

Embodiment 1

[0022] Example 1: The 2-year-old Pingtan stem bark was cut into small pieces of 2 mm × 20 mm, and 5 pieces were put into the pectinase solution of pH 4.0, the concentration of the pectinase solution was 1494.6 U / mg, and the temperature was 30 ° C. The soaking time is 2.5 hours; then rinse the stem bark fragments after enzyme treatment with distilled water and place them in 0.6% NaOH solution, keep the temperature at 80-85°C, and boil them for 25 minutes; take them out and rinse them with distilled water, put them in clean penicillin Add 2 mL of distilled water to the bottle, press it flat with a thick glass rod until it is broken, pour it into a 10 mL centrifuge tube, centrifuge at 3500 r / min for 5 min, carefully discard the supernatant, rinse the precipitate with 1 mL of distilled water; mix well Finally, take 1 drop with a dropper, spread it on a glass slide, dry and fix it on an alcohol lamp; then stain with 10% safranin for 10 min, wash it with distilled water, and examine ...

Embodiment 2

[0023] Example 2: Cut the 2-year-old Pingtan stem bark into small pieces of 2 mm × 20 mm, put 5 pieces into the pectinase solution with pH 4.5, the concentration of the pectinase solution is 1594.6 U / mg, and the temperature is 35 ° C. The soaking time is 3 hours; then the stem bark fragments after enzyme treatment are rinsed with distilled water and placed in 0.6% NaOH solution, kept at 80-85°C, boiled for 25 minutes; taken out, rinsed with distilled water, and put in clean penicillin Add 2 mL of distilled water to the bottle, press it flat with a thick glass rod until it is broken, pour it into a 10 mL centrifuge tube, centrifuge at 3500 r / min for 5 min, carefully discard the supernatant, rinse the precipitate with 1 mL of distilled water; mix well Finally, take 1 drop with a dropper, spread it on a glass slide, dry and fix it on an alcohol lamp; then stain with 10% safranin for 10 min, wash it with distilled water, and examine it under the microscope. Repeat 5 times, that is...

Embodiment 3

[0024] Example 3: The 3-year-old Pingtan stem bark was cut into small pieces of 2 mm × 20 mm, and 5 pieces were put into the pectinase solution of pH 5.0. The concentration of the pectinase solution was 1694.6 U / mg, and the temperature was 40 ° C. The soaking time is 3.5 hours; then the stem bark fragments after enzyme treatment are rinsed with distilled water, placed in 0.6% NaOH solution, kept at 80-85°C, and boiled for 25 minutes; taken out, rinsed with distilled water, and put in clean penicillin Add 2 mL of distilled water to the bottle, press it flat with a thick glass rod until it is broken, pour it into a 10 mL centrifuge tube, centrifuge at 3500 r / min for 5 min, carefully discard the supernatant, rinse the precipitate with 1 mL of distilled water; mix well Finally, take 1 drop with a dropper, spread it on a glass slide, dry and fix it on an alcohol lamp; then stain with 10% safranin for 10 min, wash it with distilled water, and examine it under the microscope.

Abstract

The invention relates to a separation method of a pteroceltis tatarinowii fiber, and the method comprises the following steps: placing 2-3-year-old pteroceltis tatarinowii stem bark into a pectase solution with the pH value of 4.5+ / -0.5, and soaking at the temperature of 35+ / -5 DEG C for 3+ / -0.5 hours; and then flushing the pteroceltis tatarinowii stem bark after enzyme treatment with distilled water, then placing into 0.6% NaOH, cooking for 25+ / -5 minutes at the temperature of 80-85 DEG C, taking out, and washing with the distilled water, so that the pteroceltis tatarinowii fiber can be separated into complete fiber cells. The pteroceltis tatarinowii stem bark processed by the separation method can be separated into the complete and clear fiber cells, thereby providing a high-quality raw material for papermaking, greatly reducing the using quantity of alkali by mass production, reducing the consumption of chemicals, not only saving the cost, but also reducing the environmental pollution.

Description

technical field [0001] The invention relates to a method for separating green sandalwood fibers, belonging to the technical field of biological cell separation. Background technique [0002] Plant fiber is a kind of thick-walled tissue widely distributed in seed plants. Its cells are elongated, with sharp ends, and have thicker secondary walls. There are often single pits on the wall, and there are generally no cells when mature. live protoplasts. Plant fibers mainly play a role in mechanical support in plants. In the stems of plants, such as the herbaceous stems of ramie, hemp, flax and jute, there are specially developed bast fiber bundles, which can be used to make various textiles; in the woody stems of some plants, the toughness fibers are also developed, They are excellent raw materials for making special paper, such as green sandalwood, mulberry, paper mulberry, etc. [0003] The tenacity fibers of the branches of green sandalwood are the main raw materials for mak...
