I-sodium lignosulfonateyipolima yendalo.Yimveliso yemveliso yepulp, eyipolymer ye-4-hydroxy-3-methoxybenzene.Ine-dispersibility eyomeleleyo.Ngenxa yobunzima beemolekyuli ezahlukeneyo kunye namaqela asebenzayo, inamaqondo ahlukeneyo e-dispersibility.Yinto esebenzayo engaphezulu enokuthi ibhengezwe kumphezulu wamasuntswana ahlukeneyo aqinileyo kwaye inokuqhuba utshintshiselwano lwe-ion yesinyithi.Kananjalo inamaqela ahlukeneyo asebenzayo kwisakhiwo sayo, ngoko inokuvelisa i-condensation okanye i-hydrogen bonding kunye nezinye iikhompawundi.
Ngenxa yobume bayo obukhethekileyo,sodium lignosulfonateineempawu ze-physicochemical ezingaphezulu ezifana nokusasazwa, i-emulsification, i-solubilization kunye ne-adsorption.Iimveliso zayo ezilungisiweyo zisetyenziswa njenge-mineral nutrient surfactant, kwaye inkqubo yokuvelisa sele ikhulile.

Umgaqo wokusetyenziswa kwesodium lignosulfonate:
Inani leekhonkco zekhabhoni lihluka kakhulu ngokwezinto ezahlukeneyo ezithathwe kwi-lignin.Ezinye zikulungele ukuveliswa kwezichumisi kwaye ezinye zikulungele ukongeza izibulali zinambuzane.Iqulethe imisebenzi eyahlukeneyo esebenzayo, i-dispersibility kunye ne-chelation, ekulula ukudibanisa kunye nezinto zetsimbi ukwenza i-chelate state, ukuphucula iimpawu ezibonakalayo kunye neekhemikhali zezinto zezondlo zetsimbi, gcina iindleko kunye nokuphucula ukusebenza kakuhle.I-adsorption kunye ne-slow-release properties ye-lignin inokugcina ngcono ukusebenza kwesichumisi sekhemikhali kwaye yenze ukuba ikhulule ngokukhawuleza.Yimathiriyeli elungileyo ekhutshwa kancinci yesichumiso esihlanganisiweyo sendalo.I-Lignin luhlobo lwe-polycyclic macromolecular organic compound equkethe amaqela amaninzi angalunganga, anobudlelwane obuluqilima bee-ion zentsimbi eziphakamileyo emhlabeni.
I-sodium lignosulfonateingasetyenziselwa ukulungisa izitshabalalisi.I-Lignin inommandla omkhulu ocacileyo kwaye iqulethe iindidi ezininzi zamaqela asebenzayo, anokusetyenziswa njenge-arhente yokukhupha kancinane yesibulali-zinambuzane.
Kukho umahluko kwisakhiwo phakathi kwe-lignin kwizityalo kunye ne-lignin emva kokuhlukana.Udonga olusandula ukwenziwa lweseli yezityalo luncinci kwaye lutyebile kwiipolysaccharides ezineasidi ezifana ne-pectin, ethi ngokuthe ngcembe ivelise i-cellulose kunye ne-hemicellulose.Iiseli ziyahlula kwiiseli ezahlukeneyo zexylem (iintsinga zokhuni, iitracheid kunye neenqanawa, njl.njl.).Xa i-S1 yodonga lwesibini lwenziwe, i-lignin iqala ukwenza ukusuka kwiimbombo zodonga oluphambili.Le nto ibizwa ngokuba yi-lignification.Ngokukhula kwezicubu zezityalo, i-lignification ikhula ngokubhekiselele kwi-intercellular layer, udonga oluphambili kunye nodonga lwesibini.I-Lignin ifakwa ngokuthe ngcembe ngaphakathi naphakathi kweendonga zeeseli, idibanisa iiseli kunye neeseli kunye.Ngethuba lokunyanzeliswa kweendonga zeeseli zezityalo, i-lignin ingena kwiindonga zeseli, inyusa ubunzima beendonga zeeseli, ikhuthaza ukubunjwa kwezicubu zoomatshini, kunye nokuphucula amandla omatshini kunye nomthwalo wokuthwala iiseli zezityalo kunye nezicubu;I-Lignin yenza i-cell wall hydrophobic kwaye yenza iiseli zesityalo zingabonakali, zinika isiqinisekiso esithembekileyo sokuthuthwa komgama omde wamanzi, amaminerali kunye nezinto eziphilayo kumzimba wesityalo;Ukungeniswa kwe-lignin kwindonga yeeseli kwakhona kubumba ngokufanelekileyo umqobo womzimba, ukuthintela ngokufanelekileyo ukuhlaselwa kweentlobo ezahlukeneyo zezityalo;Ithintela iimolekyuli zokuqhuba ezikwixylem ekuphumeni kwamanzi, kwaye kwangaxeshanye yenza ukuba izityalo ezisemhlabeni zikwazi ukuphila kwindawo eyomileyo, nto leyo eyandisa ukuxhathisa kwezifo zesityalo.I-Lignin idlala indima ekubopheni i-cellulose, i-hemicellulose kunye neetyuwa ze-inorganic (ikakhulukazi i-silicate) kwizityalo.
Izinto ezichaphazela ukubola kwe-lignin ziquka umhlaba pH, ukufuma kunye neemeko zemozulu.Ezinye izinto, ezifana nokufumaneka kwenitrogen kunye nemineralogy yomhlaba, nazo zinefuthe.I-adsorption ye-Fe kunye ne-Al oxides kwi-lignin inokunciphisa ukubola kwe-lignin.
