Sodium lignosulfonatebụ polymer eke. Ọ bụ ngwaahịa sitere na mmepụta pulp, nke bụ polymer nke 4-hydroxy-3-methoxybenzene. Ọ nwere ike dispersibility. N'ihi ịdị arọ molekụla dị iche iche na otu ọrụ, ọ nwere ogo dị iche iche nke dispersibility. Ọ bụ ihe na-arụ ọrụ n'elu nke nwere ike adsorbed n'elu ihe dị iche iche siri ike ma nwee ike iduzi mgbanwe ion metal. Ọ nwekwara ụdị dị iche iche na-arụ ọrụ na nhazi ya, ya mere ọ nwere ike ịmepụta condensation ma ọ bụ hydrogen bonding na ndị ọzọ ogige.
N'ihi nhazi ya pụrụ iche.sodium lignosulfonatenwere n'elu physicochemical Njirimara dị ka mgbasa, emulsification, solubilization na adsorption. A na-eji ngwaahịa ndị emezigharịrị eme ihe dị ka ihe na-edozi ahụ na-edozi ahụ, na usoro mmepụta ahụ etoola.
Ngwa ụkpụrụ nkesodium lignosulfonate:
Ọnụ ọgụgụ nke ụdọ carbon dịgasị iche iche dabere na ihe dị iche iche ewepụtara na lignin. Ụfọdụ dabara maka mmepụta fatịlaịza ma ụfọdụ dabara maka mgbakwunye pesticide. Ọ nwere ọrụ dị iche iche na-arụsi ọrụ ike, dispersibility na chelation, nke dị mfe ijikọta ya na ihe ndị dị na ígwè iji mepụta steeti chelate, meziwanye anụ ahụ na kemịkal nke ihe ndị na-edozi ígwè, na-echekwa ego ma melite arụmọrụ. Mgbasa ozi na ngwa ngwa-ahapụ nke lignin nwere ike ịnọgide na-arụ ọrụ nke fatịlaịza kemịkalụ ma mee ka ọ hapụ ya nwayọ. Ọ bụ ihe dị mma na-ewepụta ngwa ngwa maka fatịlaịza ngwakọta organic. Lignin bụ ụdị polycyclic macromolecular organic compound nwere ọtụtụ ndị na-adịghị mma, nke nwere mmekọrịta siri ike maka ion ọla dị elu na ala.
Sodium lignosulfonatenwekwara ike iji maka nhazi pesticide. Lignin nwere nnukwu ebe elu akọwapụtara ma nwee ụdị dị iche iche na-arụsi ọrụ ike, nke enwere ike iji dị ka onye na-ahapụ ngwa ngwa ọgwụ pesticide.
Enwere ọdịiche dị na nhazi n'etiti lignin na osisi na lignin mgbe nkewa gasịrị. Mgbidi cell ọhụrụ nke nkewa sel osisi emepụtara dị gịrịgịrị ma baa ụba na polysaccharides acid dị ka pectin, nke na-eji nwayọọ nwayọọ na-emepụta cellulose na hemicellulose. Selụ dị iche iche n'ime mkpụrụ ndụ xylem dị iche iche (eriri osisi, tracheid na arịa, wdg). Mgbe e guzobere oyi akwa S1 nke mgbidi nke abụọ, lignin na-amalite ịmalite site na nkuku nke mgbidi mbụ. A na-akpọkarị ihe omume a lignification. Site na ntozu nke anụ ahụ osisi, lignification na-etolite n'akụkụ oyi akwa intercellular, mgbidi mbụ na mgbidi nke abụọ. A na-edobe Lignin nke nta nke nta na n'etiti mgbidi cell, na-ejikọta sel na sel ọnụ. N'oge lignification nke osisi cell mgbidi, lignin penetrates n'ime cell mgbidi, na-amụba hardness nke cell mgbidi, na-akwalite guzobe n'ibu anụ ahụ, na-eme ka n'ibu ike na ibu-ebu ikike nke osisi mkpụrụ ndụ na anụ ahụ; Lignin na-eme ka mgbidi cell hydrophobic na-eme ka mkpụrụ ndụ ihe ọkụkụ ghara ịmị mkpụrụ, na-enye nkwa a pụrụ ịdabere na ya maka njem dị anya nke mmiri, mineral na ihe ndị dị ndụ na ahụ osisi; Ntinye nke lignin n'ime mgbidi cell na-emepụtakwa ihe mgbochi anụ ahụ, na-egbochi mbuso agha dị iche iche nke osisi; Ọ na-egbochi ụmụ irighiri ihe ndị na-eduzi na xylem ịpụpụ mmiri, n'otu oge ahụ na-emekwa ka ihe ọkụkụ dị n'ụwa nwee ike ịdị ndụ n'ebe dịtụ ala kpọrọ nkụ, nke na-eme ka ọrịa nke osisi ahụ dịkwuo mma. Lignin na-ekere òkè na ijikọ cellulose, hemicellulose na nnu inorganic (karịsịa silicate) na osisi.
Ihe na-emetụta ire ere lignin gụnyere pH ala, mmiri na ọnọdụ ihu igwe. Ihe ndị ọzọ, dị ka ịnweta nitrogen na ala mineralogy, nwekwara mmetụta. Mgbasa ozi nke Fe na Al oxides na lignin nwere ike ibelata ire ere nke lignin.
