Sodium alginate use?
1. In printing and dyeing industry, sodium alginate has unique
properties, print out pattern bright-coloured, line is clear, the
color yield high, colour and lustre is uniform, ink the drying
speed is fast, easy desizing, permeability and feel is the best.
Middle and low viscosity sodium alginate are suitable for dyeing
and printing requirements.
2.In the textile industry, sodium alginate can improve cotton gloss
and strength, weaving without fuzz, not to drop powder, cloth cover
smooth, easy elution; Sodium alginate used for warp sizing, not
only to cotton fiber effectively, the synthetic fiber sizing, also
can obtain good results.
3.Substitute for ice cream stabilizer, can control the formation of
ice crystals, improve the ice cream taste; in fine dried noodles,
vermicelli rice flour manufacturing, adding sodium alginate can
improve the cohesion, make its tensile strength bending degree,
reduce the breakage rate; in bread, cakes products added sodium
alginate, can improve its internal organization homogeneity prolong
storage time; sodium alginate can also be made into various gel
food, maintain good colloid form, used in artificial imitation
food.
4.In the pharmaceutical industry, alginate can be used as a dental
impression material, not only cheap, simple operation, print the
tooth is more accurate; sodium alginate can also be made into
various dosage forms of hemostasis, hemostatic gauze, gauze
sponges, scald, spray haemostatic, etc..
5.Paper sizing water sodium alginate solution instead of part of
the rosin or paper surface sizing dispersant,can increase paper
surface smoothness, and can adjust printing ink, wax oil
absorption, improve paper resistance to flexible.
6.Used for welding electrode :Electrode material with sodium
alginate mixing, can be bonded by negative coating and wet coating
material, resulting in the extrusion process with sufficient
plasticity, but also in the use of welding process is easy to burn
to ashes, reducing spatter.
7.Sodium alginate can also be applied to resin coating, rubber
paste agent, the battery pole spacing layer and water treatment. In
agricultural respect, can be used as a seed treatment, insecticide,
antiviral materials application.
