Embodiment 1
[0031] This example is a small test of atmospheric degumming using the present invention.
[0032] The process steps and parameters are as follows:
[0033] Put the raw hemp (with low colloid content) into a cage (2kg / cage); soak acid: put the raw hemp into the H with a concentration of 2g / L 2 SO 4 Soak in an aqueous solution at 50℃ for 2 hours; wash one piece in water; wash hemp with waste lye: put raw hemp into the scouring waste liquid, add 20g of activator JX-01, soak for 20min at 100℃; soak hemp in concentrated alkali :Put the raw hemp treated by the above process into the NaOH aqueous solution with a concentration of 40g / L, soak for 20min at 40℃; stacking: room temperature 4h; scouring: scouring aid ZL-0220g, water glass 80g, caustic soda 200g, 20kg of water, boiled for 2h at normal pressure; boiling water to wash hemp: put it in tap water and boil for 10min; knock hemp 7 times; first pickling: wash with 1g / L sulfuric acid aqueous solution for 5 minutes; rinse: use Wash with...

[0038] This example is a small test of atmospheric degumming using the present invention.
[0039] The process steps and parameters are as follows:
[0040] Put the raw hemp (high colloid content) in a cage (2kg / cage); soak acid: put the raw hemp into the H with a concentration of 3.5g / L 2 SO 4 Soak in an aqueous solution at 50°C for 2 hours; wash once with water; wash hemp with waste lye: Put raw hemp into the scouring waste liquid, add 160g of activator JX-01, soak for 30min at 80°C; soak hemp in concentrated alkali : Put the raw hemp processed by the above process into a NaOH aqueous solution with a concentration of 80g / L and soak for 40 minutes at 60°C; stacking: room temperature for 4 hours; scouring: scouring aid ZL-0240g, water glass 80g, 240g of caustic soda, 20kg of water, boiled at normal pressure for 3 hours; washing hemp in boiling water: put it in tap water and boil for 10 minutes; knock hemp 7 times; first pickling: wash with sulfuric acid aqueous solution with a con...
Embodiment 3
[0045] A hemp industry limited company uses the present invention to perform atmospheric degumming production.
[0046] The production process and parameters are as follows:
[0047] Put the raw hemp (with moderate gum content) in a cage (500kg / cage); soak acid: put the raw hemp into the H with a concentration of 3.5g / L 2 SO 4Soak in an aqueous solution at 55°C for 2 hours; wash once with water; wash hemp with waste lye: put raw hemp into the scouring waste liquid, add 25kg of activator JX-01, soak for 20 min at 100°C; soak hemp in concentrated alkali :Put the raw hemp processed by the above process into the NaOH aqueous solution with a concentration of 60g / L and soak for 30min at 50℃; stacking: 4 hours at room temperature; scouring: scouring aid ZL-0220kg, water glass 20kg, 60kg of caustic soda, 5000kg of water, boil at normal pressure for 3 hours; wash hemp in boiling water (put it in tap water and boil for 10 minutes; knock hemp 7 times; first pickling: wash with sulfuric acid ...
