As a manufacturer of sodium carboxymethyl cellulose, let's talk about the characteristics of sodium carboxymethyl cellulose products. Sodium carboxymethyl cellulose is widely used in industry, construction, medicine, food, textile, ceramics and other fields. It is odorless, tasteless, non-toxic, and its appearance is white or yellowish fiber granular powder.
1, CMC aqueous solution preservation: low temperature or stable under sunlight, but due to temperature changes will cause the solution acid alkaline changes. Under the influence of ultraviolet radiation or microorganisms, it will cause the viscosity of the solution to decrease or even putrefaction. If it needs to be stored for a long time, it is necessary to add suitable preservatives.
2, CMC aqueous solution preparation method: first make the particles evenly wet, can significantly increase the dissolution rate.
3, CMC has moisture absorption, preservation should pay attention to moisture.
4, zinc, copper, lead, aluminum, silver, iron, tin, chromium and other heavy metal salts can make CMC precipitation.
5. Precipitation of aqueous solution below PH2.5 can be restored after neutralization with alkali.
6, calcium, magnesium and salt and other salts, although the CMC does not have a precipitation effect, but will reduce the viscosity of the solution.
7, CMC and other water-soluble glue and softener, resin, etc. are compatible.
8, CMC due to different processing, the appearance can be fine powder, coarse or fibrous, and physical and chemical properties have nothing to do.
9, CMC powder use method is simple, in cold water or 40-50 ℃ warm water conditions, can be directly added to dissolve.
That's all for today's sharing. Everyone is interested and welcome to pay attention to us.
