In the pulping process. Sodium carbonate or sodium hydroxide, calcium oxide, or a substituted calcium hydroxide. This method is relatively rare, because sodium carbonate or sodium hydroxide, is usually higher than the price of calcium oxide or calcium hydroxide. With pulp mill waste as a raw material,Sulfite or bisulfate process Bisulfite pulping of calcium contained […]
Lignsulphonate Used As Additive of CWS
March 30, 2015 by
When used as an additive to coal water slurry (CWS), lignosulphonate has the shortcomings of low concentration and high ignition point. To solve these problems, in this article, sodium lignosulphonate was used as a raw material to find out the optimum process to make additives, such as aminated lignosulphonate condensated sulfonated naphthalene (LCSN), aminated lignosulphonate-polystyrene-acrylic (LPSA) and […]
Preparation and Application of Modified Sodium Lignosulfonate Hydrogel
March 30, 2015 by
Lignosulfonate have a tri-dimensional network like structure containing hydroxyl,carboxyl and sulphonyl groups in their molecules, these structural features therotically ensured them to be a good raw material for preparing the hydrogel. This paper focuses on the development and utilization of lignosulfonate. Firstly, we studied the preparation of lignosulfonate hydrogel, made an investigation into the removal […]
Lignosulfonate can be used for feed addtives also pellet binder
February 8, 2015 by
Lignosulfonate can be used for feed addtives also pellet binder Especially sodium lignosulfonate , calcium lignosulfonate ,sodium lignohumate .they have brass smell very good for feed additive. Provide necessary sodium and calcium which is inorganic electrolyte for animal health and need to maintain good level. Balance beneficial bacteria like intestinal flora to promote feed efficiency thus increase […]
lignin & Lignosulfonate
January 21, 2015 by
Lignin is exist with cellulose in wood, straw and other plant working as binder of cells walls,so naturally has good binding capacity. These is a lot of ways to separate the lignin and cellulose. Most easily way is popular used in China ,they just treated NaOH to separate lignin and cellulose .Cellulose is used as […]
Super Sodium Lignosulfonate
January 10, 2015 by
Super Sodium Lignosulfonate is extracted from pure lignin,which is obtained after treated acid to wood or straw,to get rid of cellulose and sugar.It is pure lignin non soluble in water.Then treated by NaOH to get pure sodium lignosulfoate around 95% of lignosulfonate content. Specifications:Solubility 99%min on dry basis,Lignosulfonate 95%min. Function:1.Used in construction as water reducing agent;2.binder […]
Sodium lignosulfonate application
March 2, 2014 by
The opportunities are sustaintialas far as commercial of lignosulphonates are concerned. To list a few, the major ones as follows. a) Oil and Grease Industry : The lignosulphonates are used to stabilize the emulsions containing water and dispresent used in drilling of oil wells. These emulsions are used to improve the properties of drilling mud […]
Sodium Lignosulfonate Structurer
October 31, 2013 by
Sodium lignosulfonate is a natural polymer has three aromatic alcohols coniferyl alcohols, p-coumaryl alcohol, sinapyl alcohol, coniferyl alcohols is the principla. It has a strong dispersion capacity, due to the molecular weight and the type of functional group with varying degrees of dispersion capability.Also is a natural surfactant. Sodium lignosulfonate has strong cation exchange capability, […]
What is lignosulfonate
October 31, 2013 by
what is lignosulfonate Lignosulphonate, or lignosulfonate, or sulfonated lignin, (CAS No. 8061-51-6) are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. Sodium lignosulphonate or calcium lignosulphonate have very […]
