Beijing Giant Hemu Technology Co., Ltd

Lignin is a naturally occurring polymer that holds the cellulose fibers together in wood and other plant material. Since it is resourceful, non-poisonous and rich in active groups, lignin have been widely used in many fields, such as construction, chemical industry???etallurgical industry and petroleum industry, etc.
Hemu sodium lignosulphonate is rich in active groups like hydroxyl and sulphonic group. These groups endow HM-NP1 good solubility, high surface activity and excellent dispersion ability, low air entraining and sustained release. Thereby, it can be used as water reducing agents to save the amount of cement in concrete and improve the strength of concrete.
