Bột HPMC

Bột HPMC được tinh chế từ bông sau khi kiềm hóa. Nó sử dụng propylen oxit và metyl clorua làm tác nhân ete hóa để tạo ra ete hỗn hợp xenluloza không ion sau một loạt phản ứng. Công ty TNHH Milestone Industrial có 20 năm kinh nghiệm trong việc sản xuất bột HPMC, với các phòng thí nghiệm và nhà xưởng chuyên nghiệp, đồng thời đảm bảo dịch vụ sau bán hàng hiệu quả. Nó có thể tùy chỉnh bột HPMC với các độ nhớt khác nhau theo nhu cầu của khách hàng.

Bột HPMC

Bột HPMC is refined from cotton after alkalization. It uses propylene oxide and methyl chloride as etherification agents to produce non-ionic cellulose mixed ether after a series of reactions. Milestone Industrial Co. Ltd. has 20 years of experience in the production of HPMC powder, with professional laboratories and workshops, and efficient after-sales service guarantee. It can customize Bột HPMC with different viscosities according to customer needs.

Bột HPMC product features:

1. Bột HPMC is easily soluble in cold water, hot water will dissolve. Its gelation temperature in hot water is significantly higher than that of methyl cellulose. The dissolution in cold water is also much better than methyl cellulose.

2. The viscosity of Bột HPMC is related to the molecular weight. When the molecular weight is large, the viscosity is high. Temperature will also affect its viscosity, as the temperature increases, the viscosity decreases. But the high viscosity of Bột HPMC is lower than that of methyl cellulose.

3. The water retention capacity of Bột HPMC depends on its added amount, viscosity, etc.; the water retention rate is higher than that of methyl cellulose.

4. Bột HPMC is stable to acid and alkali, and its aqueous solution is stable in the range of pH = 2-12. Caustic soda and lime water have little effect on its performance, but alkali can accelerate its dissolution and slightly increase its viscosity. Bột HPMC is stable to ordinary salt, but when the concentration of the salt solution is high, the viscosity of the Bột HPMC solution tends to increase.

5. Bột HPMC can be mixed with water-soluble polymer to form a uniform and high viscosity solution. Such as polyvinyl alcohol, lake water powder ether, vegetable glue, etc.

6. Bột HPMC has better enzyme resistance than methyl cellulose, and the possibility of enzymatic degradation of its solution is lower than that of methyl cellulose.

7. The adhesion between Bột HPMC and mortar structure is higher than that of methyl cellulose.

Bột HPMC produced by MST is used in the fields of water-resistant putty powder, putty paste, tempered putty, paint glue and thermal insulation mortar.
