The price of sodium alginate is affected by drought.
Description of process flow:
After the kelp is weighed, it is soaked in water 5 times the weight of dry kelp for 20 hours, drained, soaked in tap water and liquid alkali for 3 hours, and the wet kelp soaked for five times is sent to a pulverizer to be crushed to 2-3mm, washed with water, dewatered in a cage and sent to a digester; Adding 1% hot alkaline water (sodium carbonate) at 80℃ to kelp in a digester, stirring uniformly, standing for two hours, performing primary pulping, digesting for one hour, performing secondary pulping, and digesting for 0.5 hour, performing tertiary pulping, then placing in a dilution pool, diluting until it reaches Engel's for 100-120 seconds, uniformly mixing with compressed air, sending to a foaming machine for foaming and settling for 2.5-3 hours. The filtrate is pumped into a calcification system for calcification, and chlorine gas is added for bleaching at the same time, and 1% calcium solution (calcium chloride concentration is 10%) with glue solution is added, which is foamed by a foaming device and stirred at high speed, then enters an aging tank, and then enters a decalcification bucket to be decalcified with 5% hydrochloric acid, and then enters a cage for dehydration. After three decalcification, it is squeezed and dehydrated to generate alginic acid, which is then sent to a liquid phase converter and added with 75% ethanol solution. Neutralization to pH 9, centrifugal dehydration (distillation and recovery of waste ethanol solution), pelleting and granulating the centrifuged sodium alginate, drying it in a dryer until the water content is 16%-17%, then pulverizing it into 40 meshes in a mill, and packaging it after passing the inspection.

The price of alginate is affected by drought.

The reporter learned from the water conservancy department of Qingdao that since January, the average precipitation in the city has been 38.8mm, 7.4% less than the same period of the previous year, and 18.8% less than the average precipitation of 47.8mm in the same period last year! In terms of water storage, it is extremely low: the total storage capacity of 23 large and medium-sized reservoirs in the city is 37.60 million m, which is the lowest in the same period since 1982 (30.58 million cubic meters).
The production of sodium alginate will be affected by this, and the price will go up.A ton of seaweed needs 1000 cubic meters of purified water. Can sodium alginate not be nervous because of the water shortage in Jiaodong Peninsula?
