Embodiment 1
[0027] Soak non-deteriorated kelp for 2 hours, chop, wash, fix color, digest with 12% soda ash for 6 hours, coarsely filter, foam, float, filter, dilute, calcify, acidify and decalcify, wash, squeeze and dehydrate, and crush to obtain alginic acid. Take 100kg of alginic acid and 7% alginic acid weight compound magnesium salt, put it into a solid-phase neutralization tank, and react for 50 minutes. During production, use a universal indicator to detect every 10 minutes, and judge the reaction end point according to the color displayed by the indicator. Centrifuge, extrude, and dry the fully reacted material, and crush it into a 40-mesh material. The 1% glue viscosity of the crushed material is 100mPa.s, the pH value is 6.0, the moisture content is 15.0%, and the ash content is 14%.
Embodiment 2
[0029] Soak non-deteriorated kelp for 2 hours, chop, wash, fix color, digest with 12% soda ash for 6 hours, coarsely filter, foam, float, filter, dilute, calcify, acidify and decalcify, wash, squeeze and dehydrate, and crush to obtain alginic acid. Take 100kg of alginic acid and 15% alginic acid weight compound magnesium salt, put it into a solid-phase neutralization tank, and react for 75 minutes. During production, use a universal indicator to detect every 10 minutes, and judge the reaction end point according to the color displayed by the indicator. Centrifuge, extrude, and dry the fully reacted material, and crush it into a 220-mesh material. The 1% glue viscosity of the crushed material is 2000mPa.s, the pH value is 8.0, the moisture content is 12.9%, and the ash content is 28%.
Embodiment 3
[0031] Soak non-deteriorated kelp for 2 hours, chop, wash, fix color, digest with 12% soda ash for 6 hours, coarsely filter, foam, float, filter, dilute, calcify, acidify and decalcify, wash, squeeze and dehydrate, and crush to obtain alginic acid. Take 100kg of alginic acid, put it into the neutralization tank that has added 60% vol and 10% alginic acid weight compound magnesium salt in advance, react for 60 minutes, use universal indicator to detect every 10 minutes during production, according to the color displayed by the indicator, Determine the end point of the reaction. Centrifuge, extrude, and dry the fully reacted material, and crush it into a 320-mesh material. The 1% glue viscosity of the crushed material is 980mPa.s, the pH value is 6.9, the moisture content is 13.1%, and the ash content is 21%.
