Sodium Lignosulfonate CAS 8061-51-6

1. Taw qhia

Sodium lignosulfonate yog dej-soluble multi-functional polymer electrolyte, teej tug mus rau lignosulfonate, uas muaj peev xwm mus disperse biological slime, hlau oxide nplai thiab calcium phosphate scale, thiab muaj peev xwm tsim complex complexes nrog zinc ions thiab calcium ions. Sodium lignosulfonate thiab calcium lignosulfonate feem ntau yog siv los ua cov dej txo qis hauv cov khoom siv ua dej tsis zoo. Tom qab ntxiv superplasticizer rau pob zeb, pawg hydrophobic ntawm superplasticizers yog adsorbed rau saum npoo ntawm cov cement hais, thiab cov pawg hydrophilic taw tes rau cov tshuaj aqueous. nws tsim ib leeg-molecule los yog multi-molecule adsorption zaj duab xis, uas ua rau cov cement particles disperse vim hais tias ntawm kev sib nrig sib exclusion ntawm tib nto nqi, thiab tso dej ntau dhau los ntawm cov hais kom ua tiav lub hom phiaj ntawm kev txo cov dej. Nyob rau tib lub sijhawm, vim txo qhov nro ntawm cov dej thiab qhov sib cuam tshuam ntawm cov cement hais, cov dej siv tau txo qis thaum tswj cov dej ntws zoo tib yam, uas tseem ua lub luag haujlwm hauv kev txo cov dej. Nws tuaj yeem txo cov dej ntawm cov pob zeb ua kom zoo, txo cov porosity thiab ua kom cov pob zeb compactness, yog li txhim kho lub zog thiab impermeability ntawm pob zeb. Lignosulfonate yog lub ntuj macromolecule compound nrog lub cev hnyav ntawm 1000 txog 30000. Nws yog tsim los ntawm calcium lignosulfonate, sodium lignosulfonate, magnesium lignosulfonate thiab lwm yam. Feem ntau siv calcium lignosulfonate yog tsim los ntawm sulfite pulp khib nyiab cawv. Hom superplasticizer no muaj cov khoom siv nplua nuj, cov txheej txheem tsim khoom yooj yim thiab tus nqi qis, thiab tau siv dav hauv Suav teb, suav txog li 80 feem pua ​​​​ntawm tag nrho cov khoom tsim tawm ntawm superplasticizer. Tab sis nws cov nyhuv tsis zoo heev, nws muaj qhov cuam tshuam ntawm huab cua nkag thiab rov qab, yog li nws yog ib qho dej reducer, thiab nws cov nyhuv zoo dua thaum ua ke nrog cov neeg sawv cev thaum ntxov.

2. Muaj nuj nqi

2.1 Sodium lignosulfonate feem ntau yog siv los ua cov cement superplasticizer los ua cov cement agglomerated diffuse, txheeb xyuas cov ntsiab lus dej thiab ua kom nws cov fluidity. Yog li txo cov dej sib tov thiab txuag cov cement. Thaum nws yog siv nyob rau hauv lub formulation ntawm roj drilling av nkos, nws muaj peev xwm txo tau lub viscosity thiab shear quab yuam ntawm drilling av nkos, yog li tswj lub fluidity ntawm drilling av nkos, khaws inorganic av thiab inorganic ntsev impurities tshem tawm nyob rau hauv drilling, thiab tiv thaiv av nkos flocculation. Nws kuj muaj cov ntsev ua kom zoo, calcium tsis kam thiab kub tsis kam.

2.2 Dispersant rau dyes, ciab emulsions, pigments, dej kho thiab detergents.
2.3 Refractories thiab ceramic lub cev reinforcers: nyob rau hauv cov txheej txheem ntawm loj-loj phab ntsa thiab pem teb vuas thiab refractory cib, cov khoom raw khoom ntawm lub cev ntsuab tuaj yeem ruaj khov ua ke, thiab lub zog ntawm qhov qhuav dawb tuaj yeem nce ntau dua. 20 feem pua ​​thiab 60 feem pua.
2.4 Raws li ib tug binder rau hmoov thiab granular cov ntaub ntawv: rau nias pob ntawm hlau ore hmoov, lead-zinc ore hmoov, pulverized thee thiab coke hmoov; nias ntawm cam khwb cia hlau thiab cam khwb cia hlau xuab zeb pwm; extrusion ntawm av nkos cib phab ntsa thiab pem teb vuas; Cov txiaj ntsig zoo xws li lub zog siab, kev ruaj ntseg zoo thiab lubrication pwm tuaj yeem tau txais nyob rau hauv nam ntawm ore pob tsim.

3. Daim ntawv thov

Sodium lignosulfonate tsuas yog siv rau hauv resin, roj hmab, dyes, tshuaj tua kab, ceramics, cement, asphalt, pub, dej kho, thee dej slurry, pob zeb, refractories, roj teb drilling, compound chiv, smelting, casting, adhesives. Nws tau raug pov thawj los ntawm kev sim hais tias lignosulfonate muaj txiaj ntsig zoo hauv kev tiv thaiv cov av xuab zeb thiab tuaj yeem siv los ua cov xuab zeb kho tus neeg sawv cev hauv cov suab puam.

721 pom spectrophotometer, PHs23A digital PH meter, CJJ2842 kub sib nqus sib nqus.
Cov ntsiab lus ntawm sulfur ntawm sodium lignosulfonate yog 45 feem pua, lwm cov reagents yog cov tshuaj ntsuam xyuas hauv tsev, thiab cov dej siv yog dej deionized.
1.2 Cov txheej txheem sim.
Kaum ib cov qauv ntawm sodium lignosulfonate tau raug coj mus kuaj, thiab thawj peb qhov qauv tau kho nrog {{0}}MOL hydrochloric acid tov, raws li. Cov qauv 8 kawg tau ua ntej ntxiv nrog cov dej kom tsim nyog, thiab tom qab ntawd PH 0.0 1.0 thiab cov tshuaj NaOH tau hloov kho nrog HCL lossis NaOH cov tshuaj kho PH { {7}}. Thaum 30min tau muab tso rau, PH qhov tseem ceeb ntawm txhua cov tshuaj ntsuas los ntawm acidity meter yog 0.06,1.10,1.84 feem. Thaum lim nrog cov ntawv lim qhuav thiab ntim, cov lim dej yog cov kua dej txaus ntawm sodium lignosulfonate ntawm 25 degree Celsius.
