The viscosity decrease rate of sodium alginate is directly related to temperature.

　　There are many factors that affect the viscosity decrease of sodium alginate. Qingdao Nanshan Biotechnology Co., Ltd. puts forward professional answers to customers' questions. Why the viscosity of sodium alginate decreases is directly related to the temperature decrease.
　

　　The main quality index of sodium alginate is viscosity. Foreign customers are particularly strict about viscosity. If the viscosity can't meet the requ irements of the other party, the other party is likely to return it. The viscosity drops rapidly, especially in summer. The higher the temperature, the greater the drop. In addition, the viscosity will drop more when the transportation time is long. Most foreign customers can reach the other port in about 20 days, and the viscosity of sodium alginate will drop by about 5% in 20 days. Therefore, attention should be paid to the viscosity drop rate before export, and the viscosity before leaving the factory should be higher than the customer's requirements. The following is the author's experience, for reference only: if customers need low viscosity (50 ~ 100 CPS), the viscosity should be 15% higher before leaving the factory. Medium viscosity (100 ~ 400 CPS), which should be 20% higher before leaving the factory. High viscosity (500～1000CPS), which should be higher than 25% before leaving the factory. Only in this way can the viscosity of the goods reach the other port to meet the customer's requirements.
