Lignosulfonate work as binder

One of lignosulfonate famous property is binder is used in a wide range of applications. Lignosulfonates is a brown amorphous powder are the salts of lignosulfonic acid which is formed as a by-product when wood pulp is treated by the sulphite method during the manufacturing of paper.When such lignosulfonate become wet its binding capacity will exhibit.

Meanwhile a lot of industries has some fines is different to cope with,lignosulfonate could bind them into larger part to take full use of them.

Lignosulfonate’s binding capacity Could widely used for the following industries:

1. Coal Briquettes or refinery coke binder

In coal industry and refinery coke ,there always a lot of powder hard to handle,if put them directly into use lower heating energy ,Lignosulfonate could help to bind them into regular size  convert the powder into large easy to use.

Usually we mix some water and 3-5% of lignosulfonate of the total mixture the end product moisture is control less than 7%.

2. Dust suppressants(Dust control agent)and surface stabilizer

Lignosulfonate could work as effective dust control agent and surface stabilizer .As e all know lignin has strong ability to bind cellulose and fiber to increase tree firmness.So this feature could be much more environment-friendly and economic choice compared with other petroleum based products.

Thus Lignosulfonate is naturally an adhesive, working as a binding agent  in pellets or compressed materials. Also could used in Plywood & particle board,Fertilizers , casting and so on.

3. Ceramics

Lignosulfonate has different compositions and molecular dimensions (because they are polymers that can be modified by the addition of organic or inorganic groups to the molecule). They are anionic derivatives of lignin, water soluble and surfactants. Lignosulfonates can increase mechanical green and dry strength in ceramic pieces. Also, they work as lubricants during extrusion or pressing . Additions of lignosulfonates to ceramic slips can vary from 0.1 to 2.0% and they are relatively inexpensive. For pressed tiles, 1% lignosulfonate can double mechanical strength (however often a black core appears). Lignosulfonates are often used to reduce shrinkage yet maintain after-forming mechanical strength (because reduced amounts of plastic clays are needed).
Specifically,they have the following property ,better clay workability,Reduced need for die lubrication,life of wearing parts,free water also reduced energy consumption;quick drying ,increase greenth.
Reduced Baryum Carbonate need, even up to its elimination

4. Animal feed pellets

Firstly could affect the animal growth digestion ,could supply natural soluble carbohydrate ,crucial for the metabolizable energy .Live stock and poultry can be improved eating resistance ,particle strength,reduce the amount of feed powder,also reduce anti back ratio and cost.

5. Carbon black

Lignosulfonate can be applied as a binder for pyrolysis carbon black according to several patents. Lignosulfonate binders also give pellets their strength through solid type interactions (although to a less extent than starch) but also the interactions of the charged acid groups with the surface play a large role. These surface interactions could lead to stronger pellets but also might cause some problems if the surface morphology of the pyrolysis carbon black is not compatible. Nonetheless lignosulfonates present a cheap and promising option.

6. Cement

One of important function of lignosulfonate is used as additives to cement.It binds the surface of the cement particles delay its absorption of water to make it harden.So lignosulfonate will affect a lot to the hard of cement.

7.Also other industries like Fiber glasses insulation,brick and so on.
