Hydroxypropyl methyl cellulose manufacturer, focusing on the research and development, production and sales of hydroxypropyl methyl cellulose, latex powder and cellulose ether. What factors affect the dissolution time of hydroxypropyl methylcellulose cold-water quick-dissolving product (with S), that is, how fast the viscosity rises after being dispersed in water?
1. Temperature. The lower the temperature, the faster the dissolution rate.
2. PH value. For rapid dissolution, after adjusting the PH value to 8-10 with ammonia or alkaline water, the product will quickly dissolve and form a solution.
In practical applications, when making putty powder, the gray calcium is alkaline and the product will dissolve quickly. Therefore, in the production of putty powder, the dissolution time of hydroxypropyl methylcellulose is no problem. In production, cold water quick-dissolving products are not recommended, hot-melting (ordinary) products are recommended.
