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 the wood itself (the other components is cellulose and hemicellulose), is a kind of natural polymer, Content in plants usually is Cellulose >lignin >hemicellulose. lignin could be obtained from the plants  with many solutions , Contains organic solvent to obtain, lye acquisition, anthraquinone  process, etc. For lignin with sulfite method, and they will get the lignosulfonate. The biggest differences between lignin and lignosulfonate is the lignin insoluble in water, while the lignosulfonate soluble in water easily. Lignosulfonate absorb the moisture easier in the air. The application of the Lignin Can be made into lignin and phenolic resin, polyurethane resin lignin, lignin chelating resin, etc. Lignin can be made into rubber reinforcing agent. Lignin can be made into oilfield chemicals. For example: Drilling mud additives, Oil surfactant, etc Lignin can be used as building materials additives.like water reducing agent for concrete. Lignin can be used as adhesive in wood industry. Lignin can be used as surface active agent and dye dispersants in light industry. High quality of lignin can be used as coal water slurry additive.

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 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 […]

Lignosulfonate synthesis resin binder

Lignin synthesis resin binder Lignosulfonate can be used for preparing phenol – formaldehyde adhesives, phenol replace part , while improving the performance of the adhesive . For lignin phenol – formaldehyde resin binder preparation methods can be divided into two categories : direct method and modification method . Reaction direct method is simple, but less […]

Sodium Lignosulfonate Structurer

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, […]

Lignosulfonate used in concrete

Lignosulfonate-used-in-concrete Usage of lignosulfonates on the base of sodium, relating to the hydrofilizing plastificators, at the concrete manufacture and dry construction mixtures lets to reduce the consumption of components up to 10-15%. Demixing of the concrete mass reduces and its solidity rises, the speed of hardening slows down. They insert additives of lignosulfonates in the […]
