I-Lignin iwuketshezi olungancibiliki oketshezini olungathathi hlangothi nasezincibilikisini eziphilayo. Izindlela ezimbili ezivame kakhulu zokukhiqiza i-lignin ukuhlukanisa i-cellulose, i-hemicellulose ne-lignin; bese ukhiqiza i-sodium lignosulfonate kusuka ku-pulp waste nogologo (oqukethe i-lignin).

Izinkambu zohlelo lokusebenza I-sodium lignosulfonate inokuncibilika okuhle, umsebenzi ongaphezulu kwendawo kanye nezindawo zokuhlakazeka ngoba iqukethe amaqembu amaningi e-sulfonic acid namaqembu e-carboxyl namanye amaqembu asebenzayo. Inosizo oluhle lokugaya, umsebenzi ongaphezulu kwendawo kanye nezindawo zokuhlakazeka. Okuhle, ukuqina kokushisa okuphezulu, ukuzinza okuhle kokuhlakazeka kwezinga lokushisa kanye nezinye izici. I-sodium lignosulfonate iwumkhiqizo oguquliwe we-lignin wemvelo. Impushana ensundu ngokuphuzi, ayinabo ubuthi, iyavutha futhi inokuqina okuhle kwamakhemikhali.

Imikhiqizo yezwe lami ye-sodium lignosulfonate isetshenziswa kakhulu ezintweni ezijwayelekile zikakhonkolo ezinciphisa amanzi, izihlanjululi zoketshezi lokumba uwoyela, izibulala-zinambuzane, izibophezelo zempushana yamaminerali, izibophezelo zezinto eziphikisayo, njll. Inani elincane kuphela elicwengisiswayo libe izisabalalisi zikadayi, njll. Inani eliphakeme le-value-added imikhiqizo. Ngakho-ke, izinhlobonhlobo zamanje zemikhiqizo ye-lignin zisahlukanisiwe, futhi kusenemisebenzi eminingi okufanele ithuthukiswe. Ngakho-ke, esikhathini esizayo, ukuthuthukiswa kwemikhiqizo yochungechunge lwe-lignin, ukuthuthukiswa kwekhwalithi, nokwanda kwezinkambu zezicelo nezimakethe kuzoletha amaphuzu amasha okukhula komnotho.

Ukwakhiwa kwephrojekthi yenzuzo yezenhlalakahle ye-sodium lignosulfonate isebenzisa ubuchwepheshe obuthuthukisiwe bokuvimbela nokulawula ukungcola okunconywe uhulumeni ukuze kukhishwe imikhiqizo ye-lignin etshwaleni olumnyama lokwenza iphepha kanye nokunciphisa ukukhishwa kwe-COD. Ngakolunye uhlangothi, ixazulula inkinga yokwelashwa kwamanzi angcolile embonini yamaphepha futhi iqinisekisa ukuthi ukulungiswa kwamanzi angcolile esinyathelweni esilandelayo kufinyelela ezingeni. Ukukhishwa kwekhabhoni, ukusetshenziswa okuphelele kwezinsiza ezilahliwe ekuqaleni, akugcini nje ukunciphisa ukumoshwa kwezinsiza, kuvikela imvelo, kunciphisa ukungcoliswa kwemvelo kwesifunda, futhi kuthuthukisa izinga lendawo yokuhlala yabantu. Ukwakhiwa kwalo msebenzi kube nemiphumela emihle, kwanelisa uhulumeni futhi kusekela abantu.
