Problems solved by technology

[0006] The technical problem to be solved by the present invention: for the current acid-base glue remover is easy to corrode the metal base material, most of the organic solvent glue removers contain methylene chloride, benzene and ether substances, which have high toxicity, unsatisfactory cleaning effect, and pollution serious problems, the present invention at first obtains the value-added nutrient solution by cultivating the dried stems and leaves of Eichhornia chinensis, then selects several larger bacterial strains from the value-added nutrient solution to ferment, and compares the activity of the fermented liquid to obtain the degummed bacterial strain of Eichhornia chinensis, Then the degummed strains were cultivated and fermented to obtain an enzyme liquid, and the lemon peel was ultrasonically extracted to obtain a lemon extract, and then the enzyme liquid, sodium dodecylbenzene sulfonate, sodium stearate, etc. were added in sequence to obtain a green and environmentally friendly type biological glue remover

example 1

[0020] First, weigh 10g of dried water hyacinth lotus stems and leaves and add them to the Erlenmeyer flask, then add 10g of glucose and 400mL of lake water to the Erlenmeyer flask, place the Erlenmeyer flask in a water bath, control the temperature at 35°C, and cultivate for 120h to obtain the value-added culture medium Select 3 strains that produce larger yellow transparent circles from the value-added culture solution and place them in the fermenter respectively, add 200mL lake water to the fermenter, ferment for 24h at 45°C, select pectinase and xylanase in the fermentation broth The strain with high carbohydrase activity and low cellulase activity is the water hyacinth degumming strain; add the above-mentioned water hyacinth degumming strain into the fermenter, then add 600mL lake water, control the temperature at 35°C, and use 1L / min Incubate with oxygen at a high speed for 36 hours, then stop the oxygen supply, control the temperature at 45°C, ferment for 24 hours, filte...

[0026]First, weigh 20g of dried water hyacinth lotus stems and leaves and add them to the Erlenmeyer flask, then add 20g of glucose and 500mL of lake water to the Erlenmeyer flask, place the Erlenmeyer flask in a water bath, control the temperature at 45°C, and cultivate for 130h to obtain a value-added culture solution ; Select 5 strains that produce larger yellow transparent circles from the value-added culture solution and place them in the fermenter respectively, add 300mL of lake water to the fermenter, and ferment for 26h at 55°C. The strain with high carbohydrase activity and low cellulase activity is the water hyacinth degumming strain; add the above water hyacinth degumming strain into the fermenter, then add 700mL lake water, control the temperature at 45°C, and use 3L / min Incubate with oxygen at a high speed for 48 hours, then stop the oxygen flow, control the temperature at 55°C, ferment for 36 hours, filter to obtain the enzyme solution, and set aside; weigh 20g of...

Abstract

The invention relates to a preparation method of a green and environment-friendly biological glue remover, belonging to the technical field of glue removers. The present invention first obtains the value-added culture solution by culturing the dried stems and leaves of the water hyacinth, then selects several larger strains from the value-added culture solution to ferment, compares the activity of the fermentation liquid to obtain the degummed strain of the water hyacinth, and then extracts the degummed strain Cultivate and ferment to obtain enzyme liquid, ultrasonically extract lemon peel to obtain lemon extract, then add enzyme liquid, sodium dodecylbenzene sulfonate, sodium stearate, etc. in turn and stir to obtain a green and environmentally friendly biological degumming agent agent. The present invention does not contain dichloromethane, benzene and ethers, and the present invention will not cause corrosion to metal substrates, and is completely a biological adhesive remover, non-toxic, with good cleaning effect and no pollution; the present invention is simple to operate , suitable for industrial production.

Description

technical field [0001] The invention relates to a preparation method of a green and environment-friendly biological glue remover, belonging to the technical field of glue removers. Background technique [0002] In recent years, with the continuous increase of high-grade highways in our country, the driving speed of vehicles has continued to increase, and accidents such as vehicle rear-end collisions or rollovers at night and other low-visibility conditions have occurred from time to time. In order to effectively reduce the occurrence of such accidents and reduce the severity of accident consequences. It is urgent to modify or improve the main technical parameters such as the color, size specification, retroreflection coefficient and bonding force of the reflective material of the road sign and the basic requirements of the sign. This requires the replacement and replacement of the original signs. If all new materials are used, it will not only increase a lot of production c...
