The advanges of HPMC & MHEC in dry mix mortar products
November 22nd 2024
Many mortar and putty powder factories commonly use fire to detect hydroxypropyl methylcellulose, because this is the easiest and most convenient method. Here, SLEO Cellulose tells you that burning cellulose can only detect ash, not water retention. SLEO Cellulose can only say that the purity of hydroxypropyl methylcellulose affects the water retention rate, that is, the smaller the ash content, the better the water retention capacity. Conversely, the greater the ash content, the worse the water retention capacity. Here also talk about how to look at the ash content, fire detection ash content, look at the white impurities on the surface after burning, the more impurities the higher the ash content, you can evaluate the water retention based on the ash content.
Hydroxypropyl methylcellulose detection method
If you compare which of the two brands of hydroxypropyl methyl cellulose has better water retention, you can compare the workability between the sample and your current hydroxypropyl methyl cellulose, and compare which water retention is better at the same time. The good hydroxypropyl methyl cellulose reacts evenly, the methoxy and hydroxypropoxy groups can be better evenly distributed, and the water retention rate is high.
