Ligninyog qhov thib ob ntau tshaj cov peev txheej txuas ntxiv mus ntxiv hauv qhov xwm txheej.Nws muaj ntau ntau hauv cov kua dej pov tseg, ib qho me me ntawm cov khoom siv thiab rov siv dua, thiab tag nrho cov seem yog tawm mus rau hauv qhov, ua rau muaj kuab paug loj heev.Hauv lub neej niaj hnub no, kev tsis txaus thiab kev ua qias tuaj ib puag ncig tau dhau los ua ob qhov teeb meem loj uas tib neeg lub neej yuav tsum tau daws sai.Vim nws cov qauv tshwj xeeb, lignin tau tsim thiab siv los ua cov khoom siv hauv kev lag luam tshuaj.Kev sib xyaw ua ke zoo tshaj plaws ntawm cov txiaj ntsig kev noj qab haus huv thiab nyiaj txiag tau ua tiav, thiab qhov xwm txheej yeej-yeej tau ua tiav.

Tus qauv ntawmligninyog complex, thiab kev hloov ntawm nws cov qauv nyob ntawm seb hom nroj tsuag thiab txoj kev sib cais.Yog li ntawd, lubligninCov qauv ntawm cov khoom siv tawv tawv sib txawv ntawm cov nroj tsuag herbaceous thiab cov qoob loo txhua xyoo.Txawm li cas los xij, kev sib cais sib txawv yuav ua rau muaj ntau hom lignin.Sulfite pulping tuaj yeem ua rau solublelignosulfonates, thiab kraft pulping nyob rau hauv alkaline tej yam kev mob yuav tsim lignin uas yog insoluble nyob rau hauv dej tab sis soluble nyob rau hauv alkali.Sulfate lignin thiab alkali lignin, cov lignins yog lub hauv paus ntawm cov khoom siv raw.Ntawm tag nrho cov lignins, sulfate lignin raug suav hais tias yog cov khoom siv zoo rau kev tsim cov nplaum ntoo.

Cov qauv ntawm lignin muaj ntau pawg ua haujlwm, thiab lignin nws tus kheej thiab nws cov khoom hloov kho tau siv rau ntau yam.Nyob rau hauv cov cement thiab kev tsim kho engineering, lignosulfonate tuaj yeem txhim kho cov dej ntws ntawm cov cement thiab yog cov khoom siv dej ntau tshaj plaws.Tam sim no, kwv yees li 50% ntawm nws yog tsim los ntawm kev sib cais ntawm pulping thiab papermaking.Lignosulfonatesyog siv los ua cement additives.

Hais txog kev siv tshuaj lom neeg, cov qauv lignin muaj cov ntsiab lus xav tau rau cov nroj tsuag loj hlob.Cov as-ham no tuaj yeem maj mam tso tawm raws li lignin nws tus kheej degrades, yog li nws tuaj yeem siv los ua cov tshuaj tiv thaiv-tso cov chiv ua haujlwm.Lignin kuj tseem tuaj yeem sib xyaw ua ke nrog tshuaj tua kab los ntawm cov tshuaj lom neeg yooj yim, thiab tuaj yeem siv los ua tus cab rau cov tshuaj tua kab qeeb, uas yog qhov tsim nyog rau kev siv tshuaj tua kab kom ntev, kom nws tseem tuaj yeem ua tiav cov txiaj ntsig ntawm kev tswj kab tsuag hauv qab. tsawg npaum li cas.Txo cov pa phem ib puag ncig los ntawm kev siv tshuaj tua kab tsis tsim nyog thiab txo cov nqi siv tshuaj tua kab.

Hauv kev kho dej, ntau yam kev lag luamligninsthiab lawv cov khoom hloov kho muaj cov khoom zoo adsorption, tsis tsuas yog tuaj yeem adsorb hlau ions, tab sis kuj tuaj yeem siv rau adsorb anions, organics thiab lwm yam khoom hauv dej, yog li ua kom huv dej zoo.
