Sodium lignosulfonatendi polymer yachilengedwe. Ndi chopangidwa ndi zamkati, chomwe ndi polymer ya 4-hydroxy-3-methoxybene. Zimakhala ndi mphamvu zambiri. Chifukwa cha zolemera zosiyanasiyana kwa maselo a maselo a maonjezidwe, zimakhala ndi digiri yosiyanasiyana yobalalika. Ndi chinthu chogwira ntchito chomwe chimatha kutsatsa pamwamba pa tinthu tating'onoting'ono tokhazikika ndipo amatha kupanga zitsulo zosinthana ndi zitsulo. Ilinso ndi magulu ogwira ntchito mu kapangidwe kake, motero imatha kupanga zophatikiza kapena hydrogen zolumikizana ndi zina.
Chifukwa cha mawonekedwe ake apadera,sodium lignosulfonateAli ndi ma phyolochem zinthu monga kufalikira, emulsization, soubilization ndi adsorption. Zinthu zake zosinthidwa zimagwiritsidwa ntchito ngati michere ya mchere oonjeza, ndipo kapangidwe kake kazipanga kwakhala kukukhwima.

Mfundo yogwiritsira ntchitosodium lignosulfonate:
Chiwerengero cha mipando ya mpweya imasiyanasiyana malinga ndi zida zosiyanasiyana zomwe zimachotsedwa ku Lignin. Ena ndi oyenera feteleza wopanga ndipo ena ndi oyenera owonjezera tizilombo. Ili ndi ntchito zosiyanasiyana zogwira, kutanthauzira ndi kubereka, zomwe ndizosavuta kuphatikiza ndi zitsulo kuti mupange mawonekedwe achitsulo, sinthani katundu wa zitsulo ndi mankhwala a zinthu zachilengedwe, kuwononga ndalama ndikusintha. Adsorption ndi kumasulidwa kwapang'onopang'ono kwa Lignin kumatha kukhalabe ndi mphamvu ya feteleza wa mankhwala ndikupangitsa kuti isunge pang'onopang'ono. Ndi zinthu zabwino zomasulidwa pang'onopang'ono feteleza wopangidwa mwamphamvu. Ligncy ndi mtundu wa polycyclic macromarocular ortecic okhala ndi magulu osalimbikitsa ambiri, omwe ali ndi mphamvu zambiri zamankhwala apamwamba m'nthaka.
Sodium lignosulfonateikhoza kugwiritsidwanso ntchito popanga mankhwala. Lignin ali ndi malo ambiri okhazikika ndipo ali ndi magulu osiyanasiyana okangalika, omwe angagwiritsidwe ntchito ngati mankhwala ophera thupi pang'onopang'ono.
Pali kusiyana kopanga pakati pa Lignin mu zomera ndi liggen pambuyo polekanitsa. Khoma lopangidwa kumene la cell la cell limakhala loonda komanso lolemera m'matu acidic matalala monga Pectin, yomwe pang'onopang'ono imatulutsa cellose ndi helolilose. Maselo amasiyanitsa m'maselo osiyanasiyana a Xylem (ulusi wamatanda, oyenda ndi zotengera, etc.). Pamene S1 yosanjikiza yachiwiri imapangidwa, lignin imayamba kupanga kuchokera kumakona a khoma loyambirira. Izi ndizotchedwa Liquidetion. Ndi kukhwima kwa minofu yamera, kukhazikika kumayamba kulowera ku nthawi yayitali, khoma loyambirira komanso lakhoma lachiwiri. Lignin amasungidwa pang'onopang'ono mkati ndi pakati pa makhome a cell, ma cell omanga ndi maselo limodzi. Pakalengoledwe cha belelo ya cell, Lignin amalowa m'makoma a cell, kulimbikitsa kuuma kwa makoma a cell, kulimbikitsa mphamvu yamakina a minofu ya makina, ndikuwonjezera mphamvu yopanga ndi minofu; Lignin amapangira cell hydrophobic ndipo amapangitsa mbewu kuti mbewu ikhale yopanda tanthauzo, imapereka chitsimikizo chodalirika kwa mayendedwe okwera pamadzi, michere ndi zinthu zachilengedwe mu thupi la mbewu; Kulowetsedwa kwa Liggen kumakoma a cell kumapanganso motchi kwambiri, kumapangitsa kuti zikhale bwino za tizilombo toyambitsa matenda osiyanasiyana; Zimalepheretsa mamotani a maxylem kuti asatulutse madzi, ndipo nthawi yomweyo imathandizira kuti mbewu zapadziko lapansi zizikhala mu malo owuma, zomwe zimawonjezera matenda a mbewu. Lignin amagwira ntchito yomanga ma cellulose, heminellilose ndi mchere wopanda mafuta (makamaka wowoneka bwino) muzomera.
Zinthu zomwe zikukhudza Lignin kuwonongeka kwa PH, chinyezi komanso nyengo. Zina, monga kupezeka kwa nayitrogeni ndi mgonero wakuda, nawonso ali ndi zotsatira. Adsorption ya Fe ndi Al oxiss pa Ligrin imatha kuchepetsa kuwonongeka kwa Lignin.
