计算溶液所需的质量、体积或浓度。
微晶纤维素羧甲纤维素钠共处理物是微晶纤维素与适量比例的羧甲纤维素钠经特定的物理加工工艺制得,外观为白色或类白色粉末,无臭、无味,水中分散呈不溶性胶体状,其中羧甲纤维素钠起到分散和保护胶体的作用。在水、乙醇、丙酮、甲苯、稀酸或5%氨氧化钠溶液中不溶。其水溶液具有稳定的分散性,分子间也不发生缔合,在预定空间能形成水合网状结构,溶液长时间放置,不会出现分层和沉淀。
产品特性
微晶纤维素羧甲纤维素钠共处理物以独特的方式悬浮分散于水中,剪切变稀、热稳定性和触变性能好。该产品悬浮能力高,乳化性、稳定性好可以显著提高混悬剂的稳定性。
应用
常应用于药用悬浮剂、乳剂、鼻喷剂和乳膏剂中,也可作为即用型和复溶型混悬剂、乳剂、喷雾剂的增稠剂和稳定剂。

The CO treatment of microcrystalline cellulose sodium carboxymethylcellulose is made of microcrystalline cellulose and an appropriate proportion of sodium carboxymethylcellulose through a specific physical processing process. The appearance is white or quasi white powder, odorless and tasteless. It is dispersed in water as an insoluble colloid. Sodium carboxymethylcellulose plays a role in dispersing and protecting colloids. Insoluble in water, ethanol, acetone, toluene, dilute acid or 5% sodium hydroxide solution. Its aqueous solution has stable dispersibility and no association between molecules. It can form a hydrated network structure in a predetermined space. The solution will not be layered and precipitated after being placed for a long time.
Product characteristics
Microcrystalline cellulose sodium carboxymethylcellulose co treated material is suspended and dispersed in water in a unique way, with shear thinning, good thermal stability and thixotropy. The product has high suspension capacity, good emulsifying property and stability, which can significantly improve the stability of the suspension.
Application
It is often used in pharmaceutical suspensions, emulsions, nasal sprays and creams, and can also be used as thickening agent and stabilizer of ready to use and re soluble suspensions, emulsions and sprays.
