The general pH value of gypsum products is acidic or neutral. Now there are two types of construction grade hydroxypropyl methylcellulose on the market: slow-dissolving cellulose and instant cellulose (S). Instant cellulose is not suitable for gypsum systems. Products, the solubility is very poor...Read more »

Using cellulose as raw material, CMC-Na was prepared by a two-step method. The first is the alkalization process of cellulose. The cellulose reacts with sodium hydroxide to generate alkali cellulose, and then the alkali cellulose reacts with chloroacetic acid to generate CMC-Na, which is called e...Read more »
