Priorities
Appearance: white or nearly white
powder. Odorless and tasteless.
MC is non-ionic water-soluble
cellulose ether. It can be
dissolved in water below 60℃ and
alcohol 70% or acetone easily.
True specific gravity:1.26~1.31,
Bulk density:0.25-0.7g/cm3;
Carbonization temperature: 225-
230℃.
Main uses
MC can be used as adhesive,
densifiec, dispering agent.
Emulsifying agent and can be used
for film former and adhesire in
coating material industry and.
Used as adhesire and moisture
retentive agent in construction
industry, It has also wide
application in the field of oil
drilling daily chemical industry
and others. Therefore, it is
nonionic cellulose ether in
brilliant prospects.
Process for dissolving MC
1. Place the required
amount of hot water heated to
above 80℃. In a vessel. Add Mc
gradually while stirring gently.
At first MC floats on the surface
of the water. But it is gradually
dispersed to form a uniform
slurry, cool the slurry while
stirring it.
2. Place one –thirds of the
required amount of water, heated
to above dispersed to form a
uniform slurry, cool the required
amount of water heated to above
80℃. In a vessel, Disperse MC and
prepare a hot water slurry in the
same way as described in method
(1), add the remaining amount of
cold water to the hot slurry
while stirring, cool the
resultant mixture.
Package, storage, transportation
It is packed in knitting bag
covered by plastic. Net weight
25kg. prevent from raining.
And fire, wet must be avoided.
