HBS Lignosulfonate in the rubber Modification

HBS lignin in the rubber Modification HBS lignin (hereinafter referred to as HBS lignin) is a method of using a high boiling solvent extracted from plant material lignin. HBS Lignin is a new type of environment-friendly materials, and the traditional paper “black liquor” in the lignin sulfonate and alkali lignin compared with the greater chemical […]

Utilization of lignin degradation

Utilization of lignin degradation Lignin phenylpropane native structure has a structural unit in the appropriate conditions can degrade the lignin polymer is an aromatic or aliphatic organic small molecule compounds. Lignin can therefore been seen as renewable alternative to petroleum and chemical raw materials resources. Currently degrade lignin chemistry methods are: hydrolysis , pyrolysis, oxidation […]

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 […]

A bacteria which could help to decompose lignin biofuel refining

A bacteria which could help to decompose lignin biofuel refining British researchers report that they have discovered a bacterial decomposition of lignin in wood and other plant capacity , which helps crops using tree branches and stems left after harvest to refine biofuels. Tree branches and stems of many plants usually contain a large number […]

Calcium Lignosulfonate Manufacturing Process

Calcium lignosulfonate is obtained from soft wood processed in sulfite pulping method for producing paper. They small pieces of softwood is put into reaction tank to react with acidic calcium bisulfite solution for 5-6 hours under the temperature of 130 degree Centigrade. During the process the bisulfite ions reacted with native lignin to for sulfonated lignin, […]
