As a nonionic surfactant, HEC has the functions such as thickening, suspension, emulsification, adhesion, film formation, dispersion, water retention, providing protection.
Application:
1. Used in Water Emulsion Coating:
HEC is used to protect colloid in acetic alkene emulsion polymerization, improve the stability of polymer in wide pH range, make pigment and additives uniformly disperse, stable and thicken in production of finished products. It is also used as dispersant in suspensive polymer such as styrene, acrylate, acrylonitrile, etc.
2. Used in Drilling Well:
As thickener used in all kinds of mud in drilling well, well cementation and fracturing operation, HEC can make mud excellent fluidity and stability, improve the carrying power of mud in drilling well and prevent water from going into oil layer from mud, make the output of oil layer stable.
3. Used in Building Materials:
Because of its strong water retention, HEC is an excellent thickener and adhesive for cement paste and mortar to improve fluidity and operation performance, lengthen vaporizing time of water, improve the beginning strength and avoid crack. It can effectively improve the water retention and adhesive strength when used in gypsum plastering, gypsum cementing and gypsum putty.
4. Used in Toothpaste:
Because of its strong salt resistance and acid resistance, HEC can make toothpaste stable; Because of its strong water retention and emulsification power, it make tooth not easy to dry;
5. Used in Water-soluble Ink, HEC can make ink dry fast and not penetrate.
6. Moreover, HEC is widely used in textile, printing, paper making, daily chemical, etc.
Dissolving:
1. Add clean water in vessel;
2. Add HEC under low-speed agitation, agitate to make all materials fully wet;
3. After HEC fully dissolve, add other needed ingredients;
4. Add alkali or ammonia to adjust pH to 8-10, form needed viscosity.
Package, storage and transportation
Package: Plastics-paper bag outside, lined with PVC bag.
Storage :seal tightly. Exposing to the sun and rain is forbidden, to avoid absorption of moisture and contact with acid and alkali.
Transportation: As common moisture-proof chemicals.
