Sodium Lignosulfonateyog lub ntuj polymer. Nws yog ib hom khoom ntawm pulp ntau lawm, uas yog cov polymer ntawm 4-hydroxy-3-methoxybenzene. Nws muaj cov tsis muaj zog. Vim muaj ntau pab pawg hnyav thiab cov pab pawg ua haujlwm, nws muaj qib sib txawv ntawm kev tsis sib xws. Nws yog ib qho khoom siv saum npoo av uas tuaj yeem raug adsorbed nyob rau saum npoo ntawm ntau cov khoom thiab tuaj yeem ua cov hlau ion pauv. Nws tseem muaj ntau pab pawg nquag hauv nws cov qauv, yog li nws tuaj yeem tsim hws lossis hydrogen sib txuas nrog lwm cov tebchaw.
Vim nws cov qauv tshwj xeeb,Sodium LignosulfonateMuaj cov khoom saum npoo av xws li dispersion, emulsification, solubilization thiab adsorption. Nws hloov cov khoom siv tau siv los ua cov ntxhia zaub mov surfactant, thiab cov txheej txheem ntau lawm.

Daim Ntawv Thov Kev Thov ntawmSodium Lignosulfonate:
Tus naj npawb ntawm cov roj carbon chains sib txawv ntau raws li cov khoom sib txawv muab rho tawm los ntawm Lignin. Ib txhia yog tsim nyog rau cov chiv thiab qee qhov tsim nyog rau tshuaj tua kab yees. Nws muaj ntau lub zog ua haujlwm, dispersibility thiab chelation yooj yim los ua ke nrog cov khoom siv hlau thiab tshuaj lom neeg ntawm cov khoom siv hlau, txuag cov nqi thiab txhim kho kev ua haujlwm. Cov adsorption thiab qeeb-tso tawm ntawm Lignin tuaj yeem ua tau zoo dua tswj hwm cov tshuaj chiv thiab ua rau nws tso qeeb. Nws yog qhov zoo qeeb-tso cov khoom siv rau cov organic compound fertilizer. Lignin yog ib hom polycyclic macromolecular organic compound muaj ntau pab pawg tsis zoo, uas muaj kev muaj peev xwm muaj zog rau kev siv lub zog siab ions hauv av.
Sodium LignosulfonateKuj tseem siv tau rau kev ua tshuaj tua kab. Lignin muaj thaj chaw thaj chaw tshwj xeeb thiab muaj ntau pawg neeg nquag, uas tuaj yeem siv tau xws li cov tshuaj tua kab mob qeeb.
Muaj cov qauv sib txawv ntawm cov qauv ntawm cov nroj tsuag thiab lignin tom qab sib cais. Cov tshiab tsim ntawm tes ntawm phab ntsa ntawm tsob nroj cell faib yog nyias thiab nplua nuj nyob rau hauv acidic polysaccharides xws li pectin, uas nthuav dav cellulose thiab hemicellulose. Lub hlwb sib txawv rau ntau qhov tshwj xeeb xylem hlwb (ntoo ntoo, tracheids thiab cov hlab ntsha, thiab lwm yam). Thaum lub s1 txheej s1 yog tsim, Lignin pib tsim los ntawm cov ces kaum ntawm thawj phab ntsa. Qhov xwm txheej no feem ntau hu ua cov tebcem. Nrog kev loj hlob ntawm cov nroj tsuag cov ntaub so ntswg, cov lig kev cai tsim tawm ntawm cov txheej txheem interculular, phab ntsa thiab phab ntsa theem ob. Lignin yog maj mam muab tso rau hauv thiab nruab nrab ntawm cov phab ntsa ntawm tes, cov hlua khi thiab hlwb ua ke. Thaum lub sijhawm ua haujlwm ntawm tsob ntoo cell phab ntsa, ua rau lub zog ntawm tes, ntxiv cov khoom siv ntawm cov xovtooj ntawm cov nroj tsuag ntawm tes, thiab txhim kho lub peev xwm ntawm cov nroj tsuag thiab cov ntaub so ntswg; Lignin ua rau lub xov tooj ntawm tes hydrophobic thiab ua rau cov nroj tsuag tsis zoo, muab cov tshuaj tua hluav taws xob kom ruaj ntseg rau hauv cov nroj tsuag lub cev; In infiltration ntawm lignin rau hauv lub xovtooj ntawm tes kuj muaj cov khoom siv lub cev lub cev, ua kom tiv thaiv tau zoo ntawm ntau cov nroj tsuag kab ke; Nws txwv tsis pub cov molecules nyob rau hauv lub sam thiaj los ntawm kev pom cov nroj tsuag, thiab tib lub sijhawm ua rau muaj cov nroj tsuag qhuav, uas txhim kho cov nroj tsuag kab mob. Nignin plays lub luag haujlwm hauv cov cellulose cellulose, hofficellulose thiab inorganic ntsev (feem ntau silicate) hauv nroj tsuag.
Qhov cuam tshuam rau kev ua kom tiav lignin decomposition suav nrog cov hauv paus av, noo noo thiab huab cua. Lwm yam, xws li muaj cov nitrogen thiab av mineralogogy, kuj muaj kev cuam tshuam. Adsorption ntawm FE thiab Oxides ntawm Lignin tuaj yeem txo cov decomposition ntawm lignin.
