How to produce lignosulfonate

Currently, the method of separating lignin generally have two: one is outside the plant component lignin dissolved removing lignin as an insoluble components are separated by filtration; the other is just the opposite, lignin as a soluble component, will Other components of plant cellulose is dissolved and then separated from the lignin. Separation of different […]

The difference between Lignin and Lignosulphonate

Lignosulfonate is one of the derivatives of lignin. they are different in origin,chemical layout and physical properties. Lignosulfonate primary come from the sulfite process of paper pulping “black liquor” by the sulfite process, first of the separation from the“black liquor” is the sodium lignosulphonate and calcium lignosulphonate.Lignin was one of the three major components of […]

lignin Structure

lignin & Lignosulfonate

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 […]

Calcium Lignosulfonate work as water-reducing agent

Calcium Lignosulfonate  in the concrete water-reducing mechanism of enhancement of calcium lignin sulfonate and lignin sulfonate superplasticizer is an appearance of the active agent, to participate in the concrete, the hydrophobic group as directed adsorbed on cement particles appearance, so that a negative charge of cement. Cement particles having the same charge in the charge repulsion […]

Difference between lignin and lignosulfonate

Lignosulfonate is one of lignin derivatives. It is the source and lignin, chemical structures and physical properties are different. Lignosulfonate mainly from the sulfite pulping process resulting “black liquor”, separated from the black liquor extracted, mainly ligno sodium or calcium lignosulphonate. The three components of wood lignin itself (the other two are the cellulose and […]

lignosulfonate used as leather-tanning

Lignosulfonate application in leather tanning

Lignosulfonate application in leather tanning Lignosulfonate directly used in leather tanning effect is not good. Chemically modified lignosulfonate has a suitable distribution of the particle radius and bring a better soluble collagen protein reactive with a functional group reactive groups, can be used for leather tanning or retanning. Suitable modified lignosulfonate (re) tanning agent processed […]
