Sodium Sulfonate yog dab tsi?

Sodium lignosulfonate yog ib tug natural polymer nrog siab dispersibility, sib txawv degrees ntawm dispersibility vim qhov sib txawv ntawm qhov hnyav molecular thiab pab pawg ua haujlwm. Nws yog ib qho surfactant uas tuaj yeem adsorb mus rau ntau yam khoom, sib pauv hlau ions, thiab vim nws cov qauv, tuaj yeem ua kom sib xyaw lossis tsim cov ntawv cog lus hydrogen nrog lwm cov tebchaw. Cov dispersant NNO siv hauv kev lag luam dyeing yog tsim los ntawm sodium lignosulfonate.

Physical thiab Chemical Properties

Nws muaj peev xwm diffusion zoo heev, yog soluble hauv dej ntawm txhua qhov nyuaj, thiab nws cov tshuaj aqueous yog tshuaj lom neeg ruaj khov thiab biodegradable.

Lub npe hu ua lignosulfonate, qhov no anionic polyelectrolyte muaj qhov sib txawv molecular hnyav thiab cov qauv, qhia polydispersity. Nws zoo nkaus li cov hmoov daj-xim av dawb-ntws, yog hygroscopic, yooj yim yaj hauv dej tsis hais txog kev hloov pauv pH, tab sis yog insoluble hauv ethanol, acetone, thiab lwm yam organic solvents.

Kev siv davSodium lignosulfonate (lignosulfonate) yog muab los ntawm xyoob pulping txheej txheem, concentrated, hloov kho, thiab tshuaj tsuag-qhuav los ua ib lub teeb daj (xim av) dawb-flowing hmoov uas dissolves yooj yim hauv dej thiab yog tshuaj ruaj khov nyob rau hauv lub sij hawm ntev kaw cia. Raws li surfactant, nws tuaj yeem hloov kho thiab sib xyaw ua ke los tsim ntau yam khoom siv rau hauv resins, roj hmab, dyes, tshuaj tua kab, ceramics, cement, asphalt, pub, dej kho, thee-dej slurry, qhob, refractories, roj drilling, compound chiv. , smelting, casting, adhesives. Nws tau ua pov thawj zoo heev hauv kev tiv thaiv cov av desertification thiab tuaj yeem siv los ua cov xuab zeb kho tus neeg sawv cev hauv cov suab puam. Cov haujlwm tseem ceeb suav nrog:

Qhob Dej Reducer: Cov hmoov no yog cov huab cua uas tsis muaj cua nkag, cov dej retardant thiab cov anionic surfactant. Nws adsorbs thiab disperses cement, txhim kho ntau yam khoom ntawm lub cev ntawm pob zeb. Nws txo cov dej siv ntau dua 13%, txhim kho kev ua haujlwm, thiab txo qis cov dej thaum ntxov ntawm cov cement. Nws tuaj yeem muab sib xyaw rau hauv cov neeg ua haujlwm muaj zog thaum ntxov, retarders, antifreeze agents, pumping agents, thiab lwm yam, thiab thaum ua ke nrog naphthalene-raws li superplasticizers, cov kua additives ua zoo tsis muaj sediment.

Coal-Dej Slurry Additive: Ntxiv cov khoom no thaum lub sij hawm coal-dej slurry npaj nce zeb tso zis, tswj ib txwm system tej yam kev mob, txo hwj chim noj, tsub kom slurry concentration, thiab thaum lub sij hawm gasification, txo cov pa oxygen thiab thee noj, txhim kho cov roj txias efficiency thiab txhim kho cov viscosity, stability, thiab ntws. ntawm slurry.

Refractory thiab Ceramic Lub Cev Reinforcement: Hauv kev tsim cov phab ntsa loj thiab cov vuas hauv pem teb thiab cov cib refractory, nws pab khi cov khoom siv raw khoom kom ruaj khov, ua kom lub zog qhuav ntawm lub cev los ntawm 20% -60% lossis ntau dua.

Dye Industry thiab tshuaj tua kab ua Filler thiab Dispersant: Raws li ib tug dispersant thiab muab tub lim rau vat thiab disperse dyes, nws txhim khu lub zog dye, xyuas kom meej ntau xim xim, thiab txo lub sij hawm sib tsoo; nyob rau hauv kev ua tshuaj tua kab, nws ua raws li ib tug muab tub lim, dispersant, thiab suspending tus neeg saib xyuas, ho txhim kho lub ncua kev kawm ntawv thiab wetting zog ntawm wettable hmoov.

Binder rau Powdered thiab Granular Materials: Siv nyob rau hauv briquetting ntawm hlau ore hmoov, lead-zinc ore hmoov, thee hmoov av, thiab coke hmoov; nias ntawm cam khwb cia hlau thiab steel xuab zeb pwm; extrusion molding ntawm av nplaum cib, phab ntsa thiab pem teb vuas; thiab pelletizing ntawm cov ntaub ntawv ore, ua tiav lub zog siab, zoo stability, thiab pwm lubrication.

Drilling Thinner thiab Viscosity Reducer: Txhim kho qhov ntws ntawm cov roj crude thaum lub sij hawm thauj mus los, txo kev siv hluav taws xob. Nyob rau hauv cov khoom siv roj av, nws ua hauj lwm raws li ib tug huv si, dispersant, high-alkalinity additive, xeb inhibitor, antistatic tus neeg saib xyuas, emulsifying viscosity reducer, wax remover, thiab anti-wax agent.
