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 […]

About Lignosulfonate

Lignosulfonates are when traded a brown amorphous powder. They have no odour and they are not hygroscopic. They form colloidal solutions or dispersions with water but are not soluble in organic solvents. Lignosulfonates are biopolymers; they are salts of lignosulfonic acid that has been formed when pulp is manufactured by the sulphite method. The lignosulfonates […]

Lignosulfonate used in oil drilling

Lignosulfonate used in oil drilling Lignosulfonates could be used in oil drilling working as deflocculants, chemicals to prevent the coagulation of solids. Lignosulfonateand Modified lignosulfonate from wood pulp provides a chemical that is stable at the high temperatures – 150 to 250 degrees F– that occur in well bores during drilling. Clay minerals in drilling mud, such as bentonite, often coagulate. Lignosulfonates halt this process and extend the use of the bentonite.  Using purpose In oil industry – used as reagent for regulation of drilling agent; In chemical industry –used as the stabilizer, dispersing agent for manufacture of briquetted means of plants protection; In cement industry and manufacture of castables -used as cement softener and  binding material. Function In the oil refining and oil industry for drilling oil and gas wells lignosulfonates are used as a reagent to control the basic parameters of drilling fluids. Also, they are a component of gelling systems, which are low-viscosity solutions with pH 2.5-3.0. The formation of the gel leads to the redistribution of filtration flows and their better management, alignment profile pick-injection wells,restriction of water in the process, which in turn increases the recovery of oil. Using these systems lignosulfonates is possible by adsorbingproperties of surface-active additives. Just as in the mining industry, technical lignosulfonates are used to enhance various types of structures: mud pits, wells, etc.   In the petroleum refining and oil producing industries lignosulfonates are used as a flotation agent and reagent for regulating of the basicparametres of mud flushes. Also they are a component of gel forming systems – low-viscous solution with pH 2.5-3.0. Gel forming leads to  predistribution of filtration flows and their better regulation, annealing of injectability prophile, limit of inflows of water in processes, what rises oil production. Usage in these systems of lignosulfonates is possible by means of adsorbing properties of tensioactive additives. Technical lignosulfonates are used for hardening of different construction types: drill well moonpool, holes, etc, as well as in minerals industry.

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 […]
