Description
High Performance
sodium carboxymethyl starch (cms-na) (CMS)
 Product Overview:
The brand “Liduo†carboxymethyl
starch (CMS): It regards the high quality waxy corn starch and
potato starch as the main materials, We employ the innovation
technology and patent equipment to produce the environmental, high
quality and multi-application modified starch. Due to high degree
of substitution and viscosity, light crosslinking and cold-water
solubility, this product which is water-solubility and anion
polymer compound has so many characteristics such as colorless,
odorless, non-toxic, it is also quickly soluble in hot water and
forming water clear colloidal liquid and there is no undissolved
substance and could not be seperated for a long
time.  At
the same time, it could not be restricted by the production
conditions such as temperature, salt and light. It is stable in the
alkali and weak acid solution and not moulded easily. It also has
the excellent biodegradability. It could be used as a new material
in many industries and also called “Monosodium Glutamateâ€
indispensably in the modern
industry.This innovation technology and products have also
already passed through the Gansu Province Technological
Achievements Acceptance and the Gansu Province New Product
Identification in ***1. The achievements have reached the leading
domestic level, which fills up the domestic fine chemical gap in
the area of printing paste new
materials.
Application
Fields:
1.     In
the textile printing industry, sodium alginate could be replaced
wholly or partially by CMS as printing paste. After printing the
fabrics have clear outline, saturated color, smooth line, good
permeability and soft handfeel.
2.     In
the textile industry, polyvinyl alcohol (PVA) could be replaced by
CMS to use in the warp sizing. The paste has great thermal
stability, flowability, permeability, film-forming property,
abrasion performance and cohesiveness.
3.     In
the paper
industry,Carboxymethyl cellulose (CMC) can be replaced by
CMSas stabilizer and additive in the paste. It could
make the paper lustrous, improve the print performance and
strengthen the toughness and abrasion performance because of its
thickening effect. It also can be used in the surface sizing in the
paper and improve the dry and wet strength, ink absorption, oil and
water resistance.
4.     In
the building materials industry, CMC can be replaced wholly or
partially by CMS. It could be used as wallpaper glue, putty gum,
emulsion paint, thickner and decoration adhesive, etc. It also can
be used directly as an additive in the drymixed mortar. It has some
characteristics such as quickly dissolution in the water, strong
cohesiveness, favorable dispersibility, integrity, permeability,
flowability, thickening property and water-retaining
property.
5.     In
the oilfield development industry, it could be used as mud
stabilizer and fluid loss additive in the natural polymer oil
drilling fluid. It has great thermal stability, fluid loss property
and biogradability. It is also favorable to protect the hydrocarbon
reservoir.
6.     In
other fine chemistry industry, it could be used as thickener,
stabilizer, suspending agent, film-forming agent, emulsifier,
filter and excipient, etc.
7.     In
agriculture, landscaping, prevent and control desertification
industry, it could be regarded as seed pelleting agent,
water-retention agent and sand-fixing agent. Because of its
biogradability, it is no harm to the
environment.
8.     This
product has not only convenient use and good compatibility with
other agents but also high performance/price ratio. The production
cost is significantly lowered and CMS is a new generation of green
“Monosodium
Glutamateâ€.
