2.Product
use
HPMC is
used in industry for the main purpose of the production of PVC in
dispersing agent, and system suspension polymerization preparation
PVC main additives. In addition, in other petrochemical, paint,
building materials, paint remover, agricultural chemicals, printing
ink, textile printing and dyeing, ceramics, paper, cosmetics and
other products production of thickening agent, stabilizer,
emulsifier, excipients, water retention agent, film forming agent,
etc. In the application of synthetic resin, can make products with
particle neat, loose, depending on the specific gravity is
appropriate, processing characteristics of excellent performance,
so as to basically replaced gelatin and pva as dispersing agent. In
addition, in the construction industry in the process of
construction, mainly for the wall, mortar plaster, sealing and
mechanization construction; Especially in decorative construction,
used as stickup ceramic tile, marble, plastic adornment, paste high
strength, but also can reduce the dosage of cement. Used in paint
industry in thickening agent, can make the layer light is
exquisite, not to take off powder, improve the levelling
properties.

6,
Surface tension: 2% aqueous solution for ****6 dyn/cm.
7, HPMC
can be soluble in water and part of the solvent, such as the right
proportion of ethanol/ water, propyl alcohol/water,
trichloroethane, etc. Aqueous solution has the surface activity.
Transparency is high, stable performance, different specifications
of products gel temperature is different, solubility with viscosity
and change, the low viscosity, solubility, the greater the
different specifications HPMC its performance has a certain
difference, HPMC in dissolved in water are not affected by PH value
influence.
8，HPMC
with methoxy content reduce, gel point rise, water solubility
drops, the surface activity also declined.
9, HPMC
also has the thickening ability, salt resistance low ash powder, PH
stability, water retention, dimension stability, excellent
film-forming property, and a wide range of resistance to enzymatic,
dispersity and caking characteristics.
5.Remarks
Through
technology improvement and equipment upgrades, in the original
specification basis we also developed upgrade the product. The
major including surface treatment type products, speed solvent
products, modified products,
etc.(Representativemodel:*5JY****0Q3,*5JY****0S,*5JY*****0S,*5JY*****0S).
6.Packaging
*5kg
multiply paper bags with PE inner.
7.Storage and Shelf Life
2
years under cool, dry conditions in original packaging away
from heat sources. It is recommended to use the product in
rotation on a first-in first-out basis.
