How to choose the appropriate type of hydroxypropyl methylcellulose HPMC for the production of putty powder is as follows:
1 According to the model: According to the different formulas of various putty, the viscosity models of hydroxypropyl methyl cellulose and methyl cellulose are also different, from 40,000 to 100,000 are used, and the cellulose is also proposed Ether can not replace the role of other binders, adding cellulose ether can not be said to reduce the ingredients of other binders.
2. Whether the cold water-dispersed HPMC is needed: cellulose ether (bag is a surfactant, which has a high viscosity after dissolution)
It is the reason for this property. If ordinary cellulose ether is added to water, it will easily form a lump. The outside of the lump has been dissolved into a very thick solution. When the inside is wrapped, the water is difficult to penetrate, resulting in poor dissolution. .
Surface treated cellulose ether (which can delay dissolution) does not do this, and can be well dispersed in cold water (delayed dissolution, dissolve only gradually dissolves), it is a good choice to understand the above differences.
