ILignin ingeyesibili kuphela ku-celluleose ezindlini zemvelo, futhi iphindwe kabusha ngesilinganiso samathani ayizigidi eziyizinkulungwane ezingama-50 minyaka yonke. Imboni yePulp nephepha ihlukanisa cishe amathani ayizigidi eziyi-140 e-cellulose kusuka ezitshalweni minyaka yonke, futhi ithola amathani angaba yizigidi ezingama-50 wemikhiqizo, kepha kuze kube manje, ama-95% asakhishwe ngokuqondile emifuleni noma emifuleni ngokuthi " Utshwala obumnyama ". Ngemuva kokugxila, kushiswe futhi akuvamile ukusetshenziswa ngempumelelo. Ukudalulwa okukhulayo kwamandla okugcwala, izinqolobane eziningi ze-lignin, kanye nokuthuthukiswa okusheshayo kwesayensi yeLignin kunquma ukuthuthukiswa okuqhubekayo kwezinzuzo zezomnotho ze-lignin.

Izindleko zeLignin ziphansi, futhi i-lignin kanye nokutholwa kwayo kunemisebenzi ehlukahlukene, engasetshenziswa njenge-dispersants, ama-adsorbents / ophasayo, izinsizakusebenza zokuvuselelwa kwe-asphalt. Umnikelo obaluleke kakhulu we-Lignin ekuthuthukisweni okuzinzile komuntu ukuhlinzeka ngomthombo ozinzile futhi oqhubekayo wezinto eziphilayo, futhi ithemba laso libanzi kakhulu. Funda ubudlelwano phakathi kwezakhiwo ze-Lignin kanye nesakhiwo, bese usebenzisa i-lignin ukwenza ama-polymers angonakali futhi avuselelekayo. Izakhiwo ze-physichicochemical, ukucubungula izakhiwo nobuchwepheshe be-lignign sekuyimikhono yocwaningo lwamanje nge-lignin.

ILignin sulfonate yenziwa kusuka ku-Sulfite Wood Pulp pulp lignin eluhlaza ngokusebenzisa okuhlushwa, ukufakwa esikhundleni, i-oxidation, i-filtration kanye nokomisa. I-Chromium Liglosulfonate ayigcini ngokuthola umphumela wokunciphisa ukulahleka kwamanzi, kepha futhi inomphumela wokuhlanza. Ngasikhathi sinye, futhi inezici zokumelana nosawoti, ukumelana kwamazinga okushisa okuphezulu nokuhambisana okuhle. Kuyintokobulwidi enamandla okumelana nosawoti, ukumelana ne-calcium kanye nokumelana nokushisa. Imikhiqizo isetshenziswa kabanzi kumanzi ahlanzekile amanzi, amanzi olwandle, futhi agqibe usayizi kasawoti osezingeni eliphezulu, udaka olunemigwaqo ephethwe yi-calcium kanye nodaka olujulile lwe-calcium kanye nodaka olujulile lwe-ultra-deep, olungazinza ngempumelelo ukubonwa okuhle futhi kunciphise ukubonwa kodaka.

Izinkomba Zomzimba Nezamakhemikhali zeLignosulfonate:

1. Ukusebenza kuhlala kungashintshiwe ku-150 ~ 160 ℃ amahora angama-16;

2. Ukusebenza kwe-2% usawoti slurry ungcono kunalokho kwe-iron-chromium liglosulfonate;

3. Inekhono elinamandla lokulwa ne-electrolyte futhi ilungele zonke izinhlobo zodaka.

Lo mkhiqizo uhlanganiswe esikhwameni solukiwe efakwe esikhwameni sepulasitiki, ngesisindo esingama-25 kg, kanti isikhwama sokupakisha simakwe ngegama lomkhiqizo, uphawu lwentengiso, umkhiqizi womkhiqizo, umenzi kanye namanye amagama. Imikhiqizo kufanele igcinwe esitolo sokugcina ukuvimbela umswakama.
