Isakhi esiyisisekelo sesodium lignulfonateyi-benzyl propane esuselwa. Iqembu le-sulfonic acid linquma ukuthi line-solubility enhle yamanzi, kepha liyahluleka ku-ethanol, i-acetone namanye ama-sol solvents eziphilayo. I-Stufloft Softwood Lignosulfonate ingavezwa yifomula yefomula elandelayo C9h8.5O2.5 (OCH3) 0.55 (SO3H) 0.4.
Izici ezihlelekile kanye nokusatshalaliswa kwesisindo kwe-lignosulfonate okuhlukile kunquma ukuthi kwehlukile kwezinye izindlela zokwenziwa ezicini eziningi. Inempahla elandelayo engokomzimba neyomakhemikhali:
I-1.I-surface esebenzayo ye-liglosulfonate molecule inamaqembu amaningi e-hydrophilic futhi ayikho i-alkyl ye-alkyl eqondile, ngakho-ke i-solubility yayo inamandla kakhulu, futhi ama-hydrophility awo aqine kakhulu, futhi angeke abe nelungiselelo lesigaba esihlanzekile elinjengejwayelekile ukuguquguquka kwamangqamuzana okuphansi. Ngakho-ke, yize kunganciphisa ukungezwani kwesisombululo, kunamandla amancane ngaphezulu kwengxabano engaphezulu futhi ngeke kwakhiwe ama-michelles.
2.Ukubonakala kwe-slurry kungancishiswa ngokungeza inani elincane le-liglosulfonate kwi-slurry ebonakalayo ngokusebenzisa ama-adsorption nokuhlakazeka; Uma kungezwe ekumisweni kwe-Finner, ijubane lokuxazulula izinhlayiya ezimisiwe lingancishiswa. Lokhu kungenxa yokuthi iLignosulfonate ine-hydrophicility eqinile kanye ne-elektronegativity. Kwakha amaqembu anioc kwisixazululo samanzi. Lapho i-adsorbed izinhlayiya ezahlukahlukene ze-organic noma ezi-innorganic, izinhlayiya zigcina isimo sokuhlakazeka esizinzile ngenxa yokuxoshwa kwe-aniotional phakathi kwamaqembu e-anionic. Ezinye izifundo zibuye zibonise ukuthi ama-adsorption kanye nokuhlakazwa kwe-lignosulfonate kubangelwa amandla okuxoshwa kwama-elektromandla kanye nokuthambekela kwama-bubble amancane, umphumela wokuhlakazeka we-lignosulfonate uyahlukahluka ngesisindo sawo moleculate kanye nokumiswa uhlelo. Ngokuvamile, izingxenyana ezinesisindo se-molecular ezisukela ku-5000 kuya ku-40,000 zinomphumela ongcono wokuhlakazeka.
3.Chelation Lignosulfonate iqukethe okuningi phonol hydroxyl, ama-carboxylll, amaqembu e-carbonyl kanye ne-carbonyl, lapho ama-chalation e-athomu e-oksijini angakha ama-athomu we-oxygen, okuholela ekutheni athole ama-chelation we-lignin, ngaleyo ndlela abe nezimpawu ezintsha . Isibonelo, chelation of lignosulfonate nge-iron ion, i-chromium ion, njll. Ingasetshenziswa ukulungiselela ukulungiswa kodaka kodaka, futhi i-chelation futhi yenza kube nemiphumela ethile yokwelashwa kwamanzi.
4.Umsebenzi we-Bonding unezitshalo zemvelo. Njenge-adhesive, i-lignin isatshalaliswa ezungeze i-fiber futhi phakathi kwemicu emincane ngaphakathi kwe-fiber, okufakwe ngemicu kanye nemicu emincane, okwenza kube yisakhiwo esiqinile samathambo. Isizathu esenza izihlahla zingakwazi ukuwa phansi amamitha amamitha noma ngisho namakhulu amamitha yingenxa yokunamathela kwe-lignin. I-Liglosulfonate ehlukaniswe notshwala obumnyama ingashintshwa ukuze ibuyise umquba wokuqala wokunamathela, futhi ushukela kanye nokutholakala kwalo ku-loy utshwala kungasiza ukuthuthukisa amandla abo okunamathela.
5.Fooming Performance Ukusebenza kwe-Foaming kweLignosulfonate kuyafana nalokho kwe-General Pelmer Surfactants, enezimpawu zomthamo ophansi wamagwebu, kepha ukuqina okuhle kwegwebu, kanye nokusebenza kwamagwebu kwe-lignosulfonate kuzoba nomthelela othile ekusebenzeni kwawo kohlelo lokusebenza. Isibonelo, lapho isetshenziswa njengombala wamanzi okhonkolo, ngakolunye uhlangothi, ngenxa yokuthambisa ama-bubble akhiqizwa yi-lignosulfonate, uketshezi lukakhonkolo luzokhula futhi umsebenzi uzoba ngcono; Ngakolunye uhlangothi, impahla ye-fooming izokwandisa ukufakwa komoya futhi inciphise amandla kakhonkolo. Lapho isetshenziswa njengomoya ofaka amanzi anciphisa i-ejenti, kuyasiza ukuthuthukisa ukumelana nesithwathwa nokuqina kokhonkolo.
