Lignin yog ib yam khoom insoluble nyob rau hauv nruab nrab kua thiab organic solvents. Ob txoj hauv kev tshaj plaws rau kev tsim cov lignin yog cais cellulose, hemicellulose thiab lignin; thiab tom qab ntawd los tsim sodium lignosulfonate los ntawm cov kua txiv hmab txiv ntoo (lignin-muaj).
Daim ntawv thov teb Sodium lignosulfonate muaj cov solubility zoo, kev ua haujlwm siab thiab cov khoom tawg vim nws muaj ntau sulfonic acid pawg thiab carboxyl pawg thiab lwm pab pawg. Nws muaj kev sib tsoo zoo, kev ua haujlwm siab saum npoo thiab dispersion zog. Zoo, siab thermal stability, zoo kub dispersion stability thiab lwm yam ntxwv. Sodium lignosulfonate yog ib yam khoom uas hloov kho lignin. Nws yog xim av-daj hmoov, tsis muaj tshuaj lom, flammable thiab muaj tshuaj lom neeg ruaj khov.
Kuv lub teb chaws cov khoom siv sodium lignosulfonate tsuas yog siv rau hauv cov khoom siv dej kom txo qis, roj drilling kua diluents, tshuaj tua kab dispersants, ntxhia hmoov binders, refractory khoom binders, thiab lwm yam. Tsuas yog ib tug me me refined rau dye dispersants, thiab lwm yam. cov khoom. Yog li, tam sim no ntau yam ntawm cov khoom lag luam lignin tseem yog ib leeg, thiab tseem muaj ntau yam siv los tsim. Yog li ntawd, nyob rau hauv lub neej yav tom ntej, txoj kev loj hlob ntawm lignin series cov khoom, kev txhim kho kom zoo, thiab expansion ntawm daim ntawv thov teb thiab kev lag luam yuav coj tshiab economic kev loj hlob cov ntsiab lus.
Txoj haujlwm pabcuam kev noj qab haus huv ntawm sodium lignosulfonate siv cov kev tiv thaiv kev ua qias tuaj thiab tswj kev siv tshuab tau pom zoo los ntawm lub xeev kom rho tawm lignin cov khoom los ntawm papermaking dub cawv thiab txo COD emissions. Ntawm qhov tod tes, nws daws qhov teeb meem ntawm kev kho dej khib nyiab hauv kev lag luam ntawv thiab xyuas kom meej tias kev kho dej khib nyiab hauv cov kauj ruam tom ntej mus txog tus qauv. Emissions, kev siv tag nrho ntawm cov khoom pov tseg thaum xub thawj, tsis tsuas yog txo cov peev txheej pov tseg, tiv thaiv ib puag ncig, txo cov pa phem hauv cheeb tsam, thiab txhim kho cov neeg nyob ib puag ncig zoo. Txoj haujlwm tsim kho tau ua tiav cov txiaj ntsig zoo, txaus siab rau tsoomfwv thiab txhawb nqa cov neeg.
