Ingxenye eyisisekelo yesodium lignosulfonatei-benzyl propane derivative. Iqembu le-sulfonic acid linquma ukuthi linokuncibilika okuhle kwamanzi, kodwa alincibiliki ku-ethanol, i-acetone nezinye izinyibilikisi eziphilayo. I-softwood evamile i-lignosulfonate ingavezwa ngefomula yamakhemikhali elandelayo C9H8.5O2.5 (OCH3) 0.55 (SO3H) 0.4.
Izici zesakhiwo kanye nokusatshalaliswa kwesisindo samangqamuzana e-lignosulfonate kunquma ukuthi ihlukile kwamanye ama-surfactants okwenziwa ezicini eziningi. Inalezi zakhiwo ezilandelayo zomzimba namakhemikhali:
1.I-molecule esebenzayo ye-lignosulfonate inamaqembu amaningi e-hydrophilic futhi ayinawo umugqa we-alkyl chain, ngakho-ke ukuncibilika kukawoyela kubuthakathaka kakhulu, i-hydrophilicity yayo inamandla kakhulu, futhi i-hydrophobic skeleton yayo iyindilinga, futhi ayikwazi ukuba nokuhlelwa kwesigaba esihlanzekile njengokujwayelekile. ama-surfactants ama-molecule aphansi. Ngakho-ke, nakuba inganciphisa ukungezwani okungaphezulu kwesixazululo, inokulawula okuncane phezu kokungezwani kwendawo futhi ngeke yenze ama-micelles.
2.I-viscosity ye-slurry ingancishiswa ngokungeza inani elincane le-lignosulfonate ku-viscous slurry ngokusebenzisa i-adsorption kanye nokusabalalisa; Uma wengezwa ekumisweni okuncane, isivinini sokumisa izinhlayiya ezimisiwe zingancishiswa. Lokhu kungenxa yokuthi i-lignosulfonate ine-hydrophilicity eqinile kanye ne-electronegativity. Yakha amaqembu e-anionic kusisombululo esinamanzi. Uma ikhangiswa ezinhlayiyeni ezihlukahlukene zezinto eziphilayo noma ezingaphili, izinhlayiya zigcina isimo sokuhlakazeka esizinzile ngenxa yokunyathelana phakathi kwamaqembu e-anionic. Olunye ucwaningo luphinde lukhombise ukuthi ukukhangiswa nokuhlakazwa kwe-lignosulfonate kudalwa amandla okukhipha i-electrostatic kanye nokugcotshwa kwamabhamuza amancane, Ukugcotshwa kwamabhamuza amancane kuyisizathu esiyinhloko sokuhlakazeka kwawo: umphumela wokuhlakazwa kwe-lignosulfonate uyahlukahluka ngesisindo samangqamuzana nokumiswa kwawo. uhlelo. Ngokuvamile, izingxenyana ezinesisindo samangqamuzana ukusuka ku-5000 kuya ku-40,000 zinomphumela ongcono wokuhlakazeka.
I-3.chelation lignosulfonate iqukethe i-phenol hydroxyl eyengeziwe, i-alcohol hydroxyl, i-carboxyl kanye namaqembu e-carbonyl, lapho amapheya e-electron engabelwe ku-athomu ye-oxygen angakha izibopho zokuxhumanisa nama-ion ensimbi, okuholela e-chelation, okwenza i-metal chelates ye-lignin, ngaleyo ndlela ibe nezici ezintsha. . Isibonelo, i-chelation ye-lignosulfonate ene-iron ion, i-chromium ion, njll. ingasetshenziswa ukulungisa udaka lokugaya amafutha kancane, futhi i-chelation iphinde iyenze ibe nemiphumela ethile yokuvimbela ukugqwala kanye nesilinganiso, engasetshenziswa njenge-ejenti yokwelapha amanzi.
4.Umsebenzi wokuhlanganisa usezitshalweni zemvelo. Njengento enamathelayo, i-lignin isakazwa nxazonke zefayibha naphakathi kwemicu emincane engaphakathi kwefayibha, ehuqwe ngemicu nemicu emincane, okwenza ibe uhlaka lwamathambo aqinile. Isizathu sokuthi kungani izihlahla zingakwazi ukuwela phansi amashumi amamitha noma ngisho namakhulu amamitha kungenxa yokunamathela kwe-lignin. I-Lignosulfonate ehlukanisiwe nophuzo olumnyama ingashintshwa ukuze kubuyiselwe amandla okuqala okunamathela, futhi ushukela kanye nokuphuma kwawo kutshwala obudoti kungasiza ekuthuthukiseni amandla abo okunamathela ngokusebenzisa umphumela we-synergistic mutual.
5.Ukusebenza kwegwebu Ukusebenza okunegwebu kwe-lignosulfonate kufana nalokho okujwayelekile kwe-polymer surfactants, enezici zomthamo ophansi wegwebu, kodwa ukuzinza okuhle kwegwebu, kanye nokusebenza okugwebuzelayo kwe-lignosulfonate kuzoba nomthelela othile ekusebenzeni kwayo kwesicelo. Isibonelo, uma isetshenziswa njengesinciphisi samanzi esikhonkolo, ngakolunye uhlangothi, ngenxa yokugcoba ama-bubbles akhiqizwa yi-lignosulfonate, uketshezi lwekhonkrithi luzokhula futhi ukusebenza kuzoba ngcono; Ngakolunye uhlangothi, impahla enegwebu izokwandisa ukungena komoya futhi inciphise amandla kakhonkolo. Uma isetshenziswa njenge-ejenti yokunciphisa amanzi efaka umoya, kunenzuzo ukuthuthukisa ukumelana nesithwathwa nokuqina kukakhonkolo.
