Sodium lignulfonatei-polymer yemvelo. Kungumkhiqizo we-Pulp Production, okuyi-polymer ye-4-hydroxy-3-methoxybenzeene. Inokuhlakazeka okuqinile. Ngenxa yezinsimbi ezihlukile zamangqamuzana namaqembu asebenzayo, anamazinga ahlukile wokuhlakazeka. Kuyinto esebenzayo engaphezulu engaba ama-addedbed ebusweni bezinhlayiya eziqinile ezihlukene futhi ingaqhuba i-Ion ion Exchange. Iphinde ibe namaqembu ahlukahlukene asebenzayo esakhiweni sayo, ngakho-ke ingakhiqiza ukusondelana noma ukubopha ama-hydrogen namanye amakhompiyutha.
Ngenxa yesakhiwo sayo esikhethekile,sodium lignulfonateInezindawo ze-physicochemical ezifana nokuhlakazeka, i-emulsation, i-solubilization kanye ne-adsorption. Imikhiqizo yayo eguquliwe isetshenziswa njenge-mineral adtiece curfactant, futhi inqubo yokukhiqiza ibule.

Isimiso sohlelo lokusebenza sesodium lignulfonate:
Inani lamaketanga e-carbon liyahluka kakhulu ngokuya ngezinto ezahlukahlukene ezikhishwe eLignin. Ezinye zilungele ukukhiqizwa komanyolo kanti ezinye zilungele izithambiso zezinambuzane. Inemisebenzi ehlukahlukene esebenzayo, ukungafani kanye ne-chelation, okulula ukuhlanganisa nezinto zensimbi ukwenza isimo se-chelate, thuthukisa izindleko zensimbi nezakhi zomzimba, zonga izindleko futhi uthuthukise ukusebenza kahle. Izakhiwo ze-adsorption kanye nokukhishwa kancane kwe-lignign zingagcina kangcono ukusebenza komanyolo wamakhemikhali futhi zikhulule kancane. Kuyinto enhle kakhulu yokukhipha kancane umanyolo we-organic arganic. ILignin uhlobo lwe-polycyclic macromolecular comporc arganic comporc equkethe amaqembu amaningi amabi, anobudlelwano obuqinile be-inter-valent yensimbi emhlabathini.
Sodium lignulfonateIngasetjenziswa futhi ngokusebenza kwezibulala-zinambuzane. ILignin inendawo enkulu engaphezulu yendawo futhi iqukethe amaqembu ahlukahlukene asebenzayo, angasetshenziswa njenge-ejenti yokukhishwa kwe-pesticise Slote Slowle-Slowle
Kunomehluko esakhiweni phakathi kwe-lignign ezitshalweni nasebusweni be-lignin ngemuva kokwehlukana. Udonga olusanda kufakwa iseli lokuhlukaniswa kweseli lwesitshalo lunciphile futhi lucebile ku-polysaccharides acidic njenge-pectin, ekhiqiza kancane kancane i-cellulose ne-hemicellulose. Amaseli ahlukanise amaseli ahlukene we-xylem (imicu yezinkuni, ama-tracheids kanye nemikhumbi, njll.). Lapho kwakhiwa ungqimba lwe-S1 lodonga lwesibili, i-lignign iqala ukwakha emakhoneni odonga lokuqala. Le nto ngokuvamile ibizwa ngokuthi izingenzi. Ngokuvuthwa kwezicubu zezitshalo, ukufunwa kwezinsimbi kukhulela ungqimba lwenhlangano, odongeni oluyisisekelo nodonga lwesibili. Kancane kancane i-lignign ifakwa ngaphakathi nangaphakathi kwezindonga zeseli, amaseli abopha amaseli ndawonye. Ngesikhathi sokuncishiswa kwezindonga zeseli zezitshalo, i-lignin ingena ezindongeni zeseli, yandisa ubulukhuni bezindonga zeseli, ukukhuthaza ukwakheka kwezicubu zomshini, kanye nokwenza ngcono amandla okusebenza kanye namandla okuthwala umthwalo wezicubu zezitshalo nezicubu; ILignin yenza i-cell wall hydrophobic futhi yenza amaseli ezitshalo angenakufinyeleleka, anikeze isiqinisekiso esithembekile sokuhamba ibanga elide lamanzi, amaminerali kanye nezinto eziphilayo emzimbeni wesitshalo; Ukungenela kwe-lignin odongeni lweseli nakho kubumbeka ngokuvinjelwa ngokomzimba, ukuvimbela ngempumelelo ukuhlasela kwamagciwane ahlukahlukene wesitshalo; Ivimbela ama-molecule okutholwa ku-xylem ekucimeni kwamanzi, futhi ngasikhathi sinye anika amandla izitshalo zomhlaba ukuba zisinde endaweni esomile, ethuthukisa ukumelana nezifo zesitshalo. ILignin idlala indima ekubopheni kwe-cellulose, i-hemishellulose kanye nosawoti we-inorganic (ikakhulukazi izilindi) ezitshalweni.
Izici ezithinta ukubola kweLignin zifaka inhlabathi PH, umswakama kanye nezimo zezulu. Ezinye izinto, njengokutholakala kwe-nitrogen kanye nenhlabathi minerogy, futhi kunomthelela. I-adsorption of fe no-al oxides on lignin inganciphisa ukubola kwe-lignin.
